Technical Field

The invention belongs to the technical field of pressure tank valves, and particularly relates to a novel anti-repeated filling valve for a pressure tank.

Background

In a closed water circulation system, the pressure tank can balance the water quantity and the internal pressure of the system, and can avoid frequent opening of a safety valve and frequent water supplement of an automatic water supplement valve; however, in actual work, all valves need to be controlled to achieve the above effects, and particularly, the matching relationship between the safety valve and the automatic water replenishing valve is well coordinated; because the pressure limited by the safety valve is a fixed pressure value rather than a pressure range in actual work, when the pressure in the tank is lower than a set value, the automatic water replenishing valve can be controlled by the system to work, so that the phenomenon of frequently and repeatedly replenishing water in the pressure tank is easy to occur, and the service life of the related valve is greatly reduced; similarly, when the pressure tank works, the air pressure supplement in the expansion tank also needs to be controlled; therefore, in order to solve the above problems, we have devised a new type of anti-refilling valve for pressure tanks.

an adjusting seat 305 is welded on one surface of the controller 301, and the adjusting bolt 2 extends into the adjusting seat 305 and is rotatably matched with the adjusting seat 305; a plurality of electromagnets 3051 are adhered to the inner side surface of the adjusting seat 305, a plurality of permanent magnets 201 are adhered to the peripheral side surface of the adjusting bolt 2, the electromagnets 3051 are electrically connected with the resistance-variable tube 303, and the electromagnets 3051 and the permanent magnets 201 are matched with each other;

the electromagnet 3051 is electrified and magnetized, and the electromagnet 3051 has magnetism and then magnetically repels the opposite surface of the permanent magnet 201; meanwhile, the magnetism of the electromagnet 3051 increases along with the increase of the current, and the repulsive force of the permanent magnet 201 to the electromagnet 3051 also increases gradually;

the other surface of the controller 301 is welded with the power supply 306, and one surface of the power supply 306 is welded with the spiral coil 3061, and the spiral coil 3061 is electrically connected with the pressure guide rod 304 through the pressure plate 3041; a supporting spring 307 is adhered between the pressure plate 3041 and the flow pipe 302, so that the pressure guide rod 304 can be reset quickly; the pressure plate 3041 is an insulating plate structure to avoid the internal fluid from contacting the pressure guide rod 304 and causing short circuit; the connection between the flow pipe 302 and the valve pipe 1 is opened with a communication port, and the opening position of the communication port is lower than the position of the pressure plate 3041.

Preferably, a plurality of return springs 202 are welded between the circumferential side surface of the adjusting bolt 2 and the inner side surface of the adjusting seat 305; when the magnetism of the electromagnet 3051 is gradually restored along with the reduction of the current, the adjusting bolt 2 is quickly reset under the action of magnetic repulsion and spring elasticity; a sealing rotary structure is arranged between the adjusting bolt 2 and the valve tube 1.

Preferably, a ball valve sleeve 203 is welded on one end face of the adjusting bolt 2, and the ball valve sleeve 203 extends into the valve pipe 1; the ball valve sleeve 203 and the valve tube 1 are in a closed structure in the reset state of the adjusting bolt 2, that is, the valve tube 1 is in a closed structure in the normal state.

when the valve for preventing repeated filling is used, after the valve is installed, when the fluid volume or pressure in the pressure tank is sufficient, the resistance value of the resistance-variable tube 303 connected to the circuit is minimum, the current is maximum, the electromagnet 3051 and the permanent magnet 201 repel each other, and the whole valve keeps a closed structure; meanwhile, the one-way valve 101 and the pressure plate 3041 both ascend to the highest position, and the whole valve is in a closed state; when the amount of fluid or the pressure in the pressure tank is gradually reduced, the pressure plate 3041 drives the pressure guide rod 304 to be reduced, so that the resistance value of the resistance-variable tube 303 connected to the circuit is gradually increased, the current is reduced, and the magnetism of the electromagnet 3051 is gradually reduced; at this time, when the pressure tank is filled with materials, the adjusting bolt 2 needs to be rotated by means of external force, and the permanent magnet 201 and the electromagnet 3051 with reduced magnetism are mutually attracted, so that the ball valve sleeve 203 can be opened, and the materials enter the pressure tank through the one-way valve 101;

it should be further noted that when the valve actually works, an alarm control device is arranged in the controller 301, that is, when the resistance value of the access circuit is maximum, the current is minimum, and the magnetism of the electromagnet 3051 is minimum, the controller 301 enables the external force for controlling the adjusting bolt 2 to start, so as to open the valve and perform automatic water replenishing.
