The first straight line is arranged in the left-right direction, and one end of the first straight line is fixed to the front end of the valve housing 100. The first arc segment is coaxially disposed with the valve housing 100, and one end is connected to the other end of the first straight line segment. The pull rod 411 is provided with a pull groove. The outer end of the pull rod 411 is slidably mounted in the pull groove, and when the valve body 200 rotates along the preset direction, the pull rod 411 slides from the first straight line segment to the first arc segment, so that the change speed of the increment of the stretching extension of the pull rod 411 is gradually increased, the downward movement resistance of the pull rod 411 to the lower stopper 330 is gradually increased to match the continuously increased water pressure, and simultaneously, the increment speed of the downward movement resistance of the lower stopper 330 is gradually increased, so that the initial stage of the lower stopper 330 is faster and slower.

The pressing rod 421 is slidably mounted in the sliding groove, and is used for enabling the pressing rod 421 to penetrate through the valve housing 100 and then to be in sliding fit with the second limiting plate 422, so that the pressing rod 421 and the pull rod 411 work more stably.

With the above embodiments, the usage principle and the working process of the present invention are as follows: when in use, the water inlet pipe 110 is connected with hot water. After the temperature of the external environment is reduced, the air in the sealing cavity contracts to drive the rotary disc 520 to rotate along the counterclockwise direction, the rotary disc 520 rotates to drive the valve body 200 to rotate from the water sealing position to the water passing position, and under the driving of the valve body 200, the water guide plates 340 rotate around one ends hinged on the valve shell 100, so that the space between the two water guide plates 340 is enlarged, at the moment, the flow sectional area of the valve body 200 is increased, the water passing groove 210 is gradually communicated with the water passing opening, the water flow flux starts to be enlarged, according to the hydromechanics, the smaller the flow rate of the fluid sectional area is, the smaller the water pressure is, the lower stop block 330 is gradually increased by the water pressure, and the lower stop block 330 moves downwards. In the process from attaching to moving away from each other, the increment of the space between the two water deflectors 340 is changed more and more.

Therefore, during the period from the initial stage of the valve body 200 rotating from the water-sealing level to the water-passing level to the valve body 200 rotating to forty-five degrees, the first straight line segment of the pull rod 411 and the first stopper plate 412 slides to the first circular arc segment. In this process, the change speed of the increment of the stretching extension of the pulling rod 411 is gradually increased, so that the downward movement resistance of the pulling rod 411 to the lower stopper 330 is gradually increased to match the continuously increased water pressure, and the increment speed of the downward movement resistance of the lower stopper 330 is gradually increased, so that the downward movement speed of the lower stopper 330 is faster and slower at the initial stage. In this process, the increment of the speed of the lower stopper 330 pushed by the water flow and moving downward is gradually reduced to compensate the water flow flux between the two water guide plates 340 through the water passing port just when the valve body 200 rotates to the water passing position.

In the process that the valve body 200 rotates from the forty-five degree position to the ninety degree position, the pull rod 411 slides into the first arc section from the first straight section, the length is not changed any more, and the press rod 421 slides to the second straight section from the second arc section. In this process, the speed of change of the increment of the compressed amount of the pressing rod 421 is gradually decreased, so that the downward movement resistance of the pressing rod 421 to the lower stopper 330 is continuously increased to match the continuously increased water pressure, and simultaneously, the speed increment of the downward movement of the upper stopper 310 driven by the lower stopper 330 is gradually increased. In this process, the lower stopper 330 is pressed by the water flow to move down and drives the upper stopper 310 to move down to change the speed of stopping the water through opening from slow to gradually fast, so as to reduce the water flow passing through the water through opening between the two water deflectors 340 at the middle and later stages of the rotation of the valve body 200. Through the use of the pressure rod 421 and the pull rod 411, the water flux passing through the water passing port is uniformly increased during the rotation of the valve body 200 at the water passing position, so that the opening degree of the device of the invention is uniformly changed along with the temperature change.

Further, when the water pressure is higher, the pressing block 610 is more pressed downwards by water flow, so that the pressing ring 620 drives the first wedge block 630 and the second wedge block 640 to move downwards more, the initial amount of extension of the tension spring by the first wedge block 630 and the initial amount of compression of the compression spring by the second wedge block 640 are larger, the average flux of the flow flux of water passing through the water opening after adjustment by the stabilizing device is smaller, and the opening degree of the device is further reduced, so that the indoor temperature change is not too violent.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
