Technical Field

The application relates to the technical field of valves, in particular to a torsional damping pre-adjusting method of an energy-saving water leakage circuit breaker.

Background

The general water purifier equipment is generally provided with a water leakage breaker so as to immediately detect when the water purifier equipment leaks or overflows, and avoid the occurrence of the phenomenon that water accumulation causes damage to floors, decoration and articles or causes a large amount of waste of water resources. The existing water leakage circuit breaker mostly achieves the blocking effect in a linear moving mode through the mutual matching of the valve body and the piston type valve rod and the utilization of a channel in which the valve rod can move relative to the valve body. However, the linear movement of the valve rod is liable to cause the failure of the actuation due to the too large water inlet pressure, and thus the water supply can not be cut off.

The patent of grant No. CN 108533779B, grant No. 2020.05.08, grant No. CN 8932B, discloses a water leakage breaker structure, which comprises a base, a valve rod assembly, a rotating buckle assembly and an expansion body, wherein the expansion body 40 of the above patent generates a volume expansion deformation after absorbing water, and further actuates the driven arm 32 to rotate and swing counterclockwise around the rotation center of the rotating buckle assembly 30 through the hard assembly 50, so that the buckle portion 31 is disengaged from the latch of the rotating arm 22. And the torsion applied to the rotary arm 22 by the torsion spring 23 will make the rotary arm 22 and the valve rod 21 rotate and swing clockwise together, at this time, the water inlet hole 211 rotates towards the direction far away from the water inlet joint 13, thereby achieving the blocking effect.

However, the above patents still have the following problems:

problem one, the expansion body is located obliquely below the valve stem assembly 20 and water leaking from the valve stem assembly 20 is not effectively absorbed by the expansion body. So that when the water absorbed by the expansion body is expanded enough, the water quantity leaked by the whole device is large.

Second, in the critical state of expansion of the expansion body (i.e., the state in which the hook 31 is disengaged from the cantilever 22), the expansion amount is constant, and thus more accurate adjustment cannot be performed.

The third problem is that the device is not intensive, the size of the whole device far exceeds the diameter of the valve rod assembly 20, and a large amount of space is occupied.

Fourth, the torsion of the torsion spring 23 to the rotating arm 22 is constant, and cannot be adjusted.

In order to improve the defects, a circuit breaker which is more energy-saving and environment-friendly needs to be designed.

Furthermore, the water inlet end of the horizontal water inlet pipe 12 and the water outlet end of the water outlet pipe body 21 are respectively connected with a pipeline a in a sealing manner.

The breaking method of the energy-saving water leakage breaker comprises the following steps:

step 1, sealing between the water inlet assembly 1 and the water outlet assembly 2 in a normal state:

in a normal state, the water outlet side holes 22 of the water outlet assembly 2 are aligned with the water inlet transverse pipe 12, and water flows from the water inlet transverse pipe 12 to the water outlet assembly 2 through the water outlet side holes 22;

meanwhile, a trace amount of water flow enters an annular chamber between the longitudinally-arranged slim tube 11 and the water outlet tube body 21, but water leakage is avoided due to the sealing effect of the sealing lantern ring 13 e;

step 2, automatic disconnection:

when the sealing of the sealing sleeve ring 13e fails, water flows through the sealing sleeve ring 13e and the inner ring 13d of the thick pipe and is absorbed by the expansion circular ring 13f, and the expansion circular ring 13f expands when encountering water;

the expansion ring 13f acts on the transmission rear ring 44 to drive the transmission kit 4 to move downwards relative to the water inlet assembly 1 until the limiting inserting strip 47 slides out from the lower part of the limiting groove 521c, and the rotational freedom degree of the transmission kit 4 is not limited by the stopping kit 5;

the torsion spring 38 drives the torsion spring insert ring 37, the rear lantern ring 34 and the lantern ring insert key 36 to rotate;

the lantern ring inserting key 36 drives the transmission longitudinal groove 43, the transmission sleeve 42, the transmission lantern ring 41, the transmission rear ring 44 and the transmission inserting key 46 to rotate;

the transmission inserting key 46 drives the water outlet pipe body 21 and the water outlet side hole 22 to rotate until the water outlet side hole 22 and the water inlet transverse pipe 12 are completely staggered, so that the circuit breaking is realized.

As a further embodiment, between step 1 and step 2, there is further step 3, where the sensitivity of the water leakage breaker is pre-adjusted:

the internal thread cylinder 522a is pushed forwards to move forwards against the elastic force of the second compression spring 522e, and the moving component 521 is driven to move forwards until the positioning lock groove 522d is separated from the positioning lock tooth 521e, so that the rotational degree of freedom of the rotating component 522 is unlocked;

meanwhile, the internal thread cylinder 522a is rotated while being pushed forward, and the internal thread cylinder 522a acts on the external thread cylinder 521f, the shaft moving collar 521a, the longitudinally arranged circular hole 521b and the limiting groove 521c to move in the front-back direction;

the internal thread cylinder 522a is moved backwards, the positioning locking groove 522d and the positioning locking tooth 521e are locked, the rotational freedom degree of the rotating assembly 522 is locked again to be recovered to a normal state, and the position of the limiting groove 521c in the front-back direction is adjusted in the normal state;

in the step 2, the expansion ring 13f expands to extrude the transmission sleeve 4 until the limiting inserting strip 47 slides out from the lower part of the limiting groove 521c, so that unlocking is completed and short-circuit action is completed;

therefore, the front and rear positions of the limiting groove 521c are adjusted, so that the expansion degree of the expansion ring 13f during the circuit breaking action of the circuit breaker, namely, the sensitivity of the circuit breaker can be adjusted.

Further, the angle of the central angle corresponding to the arc-shaped groove 45 is greater than the angle of the central angle corresponding to the water outlet side hole 22.

Further, the arc-shaped groove 45 has a corresponding central angle of 30 ° to 110 °.

Furthermore, the water inlet end of the horizontal water inlet pipe 12 and the water outlet end of the water outlet pipe body 21 are respectively connected with a pipeline a in a sealing manner.

A torsion damping pre-adjusting method of an energy-saving water leakage breaker comprises the following steps:

step 1, both ends of the torsion spring 38 are fixed in a normal state:

the front end of the torsion spring 38 is fixed on the front lantern ring 31, and the rear end is fixed on the torsion spring insert ring 37;

the second pressure spring 33 drives the front lantern ring 31, the torsion lock teeth 32 and the fixed lock teeth 13c to be locked and connected, and the front end of the torsion spring 38 is fixed;

the torsion spring insert ring 37, the rear lantern ring 34, the limiting snap ring 35 and the lantern ring insert key 36 are in transmission connection with the transmission longitudinal groove 43, the transmission sleeve 42, the transmission lantern ring 41 and the limiting insert 47, the limiting insert 47 is locked by the limiting groove 521c, and therefore the rear end of the torsion spring 38 is fixed;

step 2, before use, the torsion of the torsion spring 38 is adjusted:

the front collar 31 is pinched and pushed forwards, so that the twist lock teeth 32 are separated from the fixed lock teeth 13c, and the rotational freedom degree of the front collar 31 is unlocked;

the front lantern ring 31 is rotated to drive the front end of the torsion spring 38 to rotate;

the degree of freedom of pushing the forward collar 31 backward so that the twist lock teeth 32 come into contact with the fixing lock teeth 13c again to lock the forward collar 31;

the torsion amount and the torsion force of the torsion spring 38 in a normal state are adjusted;

step 3, when the circuit is automatically opened, the torsion for twisting the rotation of the water outlet component 2 is adjusted:

during automatic circuit breaking, the torsion spring 38 drives the torsion spring insert ring 37, the rear lantern ring 34, the limiting snap ring 35 and the lantern ring insert key 36 to rotate, so as to drive the transmission longitudinal groove 43, the transmission sleeve 42, the transmission lantern ring 41, the transmission rear ring 44 and the transmission insert key 46 to rotate, and further drive the torsion longitudinal groove 21a and the water outlet assembly 2 to rotate;

in step 2, the torsion of the torsion spring 38 is adjusted, that is, the torsion for twisting the rotation of the water outlet assembly 2 during the automatic circuit breaking is adjusted.

Further, three or four axial rear rods 51 are provided.

Furthermore, arc-shaped through holes 13f-1 which are longitudinally communicated are evenly distributed in the expansion ring 13f in the circumferential direction.

Thanks to the improved technical scheme, the arc-shaped through hole 13f-1 can offset the radial expansion of the expansion ring 13f after water absorption expansion to a certain extent, and reduce the deformation damage possibly caused by the axial extrusion stress of the expansion ring 13f to the thick pipe body 13a and the water outlet pipe body 21. But does not influence the expansion deformation of the expansion ring 13f in the axial direction, and effectively drives the transmission sleeve 4 to act.

Further, the expansion ring 13f is made of a water-absorbent expansion material.
