It should be noted that the working principle of the present invention is divided into a working principle of realizing current limiting and a working principle of realizing voltage limiting, which are specifically as follows:

the working principle of flow limitation is that when the water pressure flowing in from the water inlet of the longitudinal pipe part 10 is gradually increased, the top part 20 is pushed to move towards the hand wheel 24 by the pressure of water, because the lower end of the top rod body 200 of the top part 20 is fixed with the piston 21, the piston 21 can also move towards the hand wheel 24, and when the piston 21 moves, the axial water passing gap formed between the outer side wall of the piston 21 and the flow limiting inclined surface 1a is gradually reduced (namely the water passing sectional area is reduced), so that the flow limitation function is realized on the water flow; it should be noted that the pushing pressure of the top member 20 can be set within a range, which can be set by changing the elastic force of the spring 22, wherein the elastic force of the spring 22 can be compressed by operating the hand wheel 24 to rotate it downwards, and conversely, the hand wheel 24 is operated to rotate it upwards to relax the spring 22, in this process, fig. 3 is an open state diagram of the connection valve of the present application in normal use;

the working principle of pressure limiting is that, as shown in fig. 4, when the pressure at the water outlet end of the transverse pipe part 11 is set to be five kilograms, the closed state of fig. 2 appears; when the piston is closed, the pressure from the water outlet end of the transverse pipe portion 11 is still kept at five kilograms, no matter how much the water pressure entering from the water inlet end of the longitudinal pipe portion 10 increases; when the pressure at the water outlet end of the transverse pipe part 11 is lower than five kilograms, the spring 22 of the adjusting device 2 pushes the piston to open, and the longitudinal pipe part 10 and the transverse pipe part 11 are in a conducting state, so that the water flow is limited.

It should be noted that, in a normal use state, the hand wheel 24 and the threaded portion of the valve housing 23 are generally screwed together by about one turn, when the water outlet end of the transverse pipe portion 11 needs to be closed, a user needs to rotate the hand wheel 24 counterclockwise to separate the hand wheel 24 from the threaded portion of the valve housing 23, the spring 22 of the adjusting device 2 loses its elastic force, and then the top member and the piston 21 are pushed to move toward the hand wheel under the pressure of the water flow, so that the piston 21 is sealed on the inner cavity wall 100 of the longitudinal pipe portion 10 of the upper portion 1a of the flow-limiting inclined surface, thereby achieving the closing function of the connection valve of the present application, and this process is to manually close the connection valve of the present application, which can be referred to fig. 3 and. It should also be noted that: when the hand wheel 24 rotates clockwise, the pressure limiting pressure is increased, and the longitudinal distance of the rotation of the hand wheel 24 can be selectively changed according to actual needs.

As described above, the connection valve with the functions of limiting the flow and the pressure according to the present invention has the following advantages:

after the connecting valve with the functions of flow limiting and pressure limiting is utilized, compared with the prior art, the connecting valve has the advantages that due to the adoption of the structure, the flow limiting inclined plane is arranged on the inner cavity wall of the longitudinal pipe part, and the adjusting device is combined, the connecting valve has the functions of flow limiting and pressure limiting, so that water is saved; meanwhile, the connecting piece arranged at the end part of the transverse pipe part is not damaged by pressure, so that the service life of the connecting piece is long, and the connecting piece is convenient to replace and maintain.
