When the pressure of the fluid is relieved, the first spring and the second spring are reset respectively, and finally the sliding block and the piston are reset

Preferably, a first sealing ring is arranged inside the first groove, the first sealing ring is fixedly connected with the piston, and the size of the first sealing ring is matched with that of the groove.

By adopting the technical scheme, the sealing ring plays a role in sealing the groove, so that fluid is prevented from flowing out of the groove, and the pressure of the fluid is ensured to be larger and larger.

Preferably, flanges are arranged on the outer sides of the water outlet and the water inlet.

By adopting the technical scheme, when the water outlet and the water inlet are both connected with the water pipe, the two flanges can ensure that the two water pipes are respectively fixed with the water outlet and the water inlet.

Preferably, a second sealing ring is fixedly arranged on the inner wall of the upper end of the water inlet, and the push rod is located inside the second sealing ring.

Adopt above-mentioned technical scheme, the fluid of water inlet upper end can be avoided to sealing washer two and the gap department outflow from push rod and water inlet outer wall to ensure that whole inside rivers pressure can be bigger and bigger.

Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1 to 2, a combined regulating valve comprises a valve body 1, a water inlet 3 is formed in one side of the valve body 1, a water outlet 4 is formed in the other side of the valve body 1, and flanges 2 are arranged on the outer sides of the water outlet 4 and the water inlet 3. When the water outlet 4 and the water inlet 3 are both connected with water pipes, the two flanges 2 can respectively fix the two water pipes with the water outlet 4 and the water inlet 3.

3 upper end both sides of water inlet have all set firmly supporting shoe 5, have all seted up logical groove 8 on two supporting shoes 5, are equipped with piston 6 between two supporting shoes 5, and the recess is seted up to water inlet 3 is inside, and the recess is linked together with water inlet 3 and delivery port 4 respectively, and 6 bottoms of piston are located inside the recess, and a recess is inside to be equipped with sealing washer 11, and sealing washer 11 is fixed connection with piston 6, and the size and the recess of sealing washer 11 cooperate.
