Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a leak-proof hydraulically controlled water valve. Background Art

[0002] Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Currently, valves are used more and more frequently.

[0003] Sealing gaskets are usually used inside existing valves, but the sealing gaskets will wear out after long-term use, which can easily cause water leakage after the valve is closed, so the sealing gaskets need to be replaced. The sealing gaskets of existing valves are subjected to high pressure when in use, resulting in faster wear and shortened replacement time intervals for the sealing gaskets, consuming a lot of manpower. Utility Model Content

[0004] The purpose of the utility model is to provide a leak-proof hydraulically controlled water valve to overcome the above-mentioned defects in the prior art.

[0005] According to a leak-proof hydraulically controlled water valve of the utility model, it includes a connecting body, connecting seats are fixedly provided at both left and right ends of the connecting body, sealing gaskets are provided at the ends away from each other of the two connecting seats, the connecting seats are connected to the sealing gaskets and have evenly distributed connecting holes, a fixing block is fixedly provided in the connecting body, a detachable valve body is fixedly provided in the fixing block, a through cavity which passes through the left and right sides is provided at the valve body, a connecting cavity is connected between the two connecting seats and the connecting body, the connecting cavity is connected to the left and right sides of the through cavity, a rotating rod is rotatably connected to the connecting body, a guide sleeve is fixedly provided on the upper end part of the connecting body to slide with the rotating rod, and the rotating rod A rotating disk is fixedly provided at the upper end, and a circular disk is fixedly connected to the lower end of the rotating rod, and two left-right symmetrical baffles are fixedly provided at the lower end of the circular disk, and a ring-shaped sliding cavity is opened in the fixed block, and the baffle is slidably matched with the side wall of the sliding cavity, and two upper and lower symmetrical baffle rings are fixedly connected on the outer periphery of the baffle and between the upper and lower side walls of the through cavity, and the outer ends of the baffle rings are chamfered, and sealing rings are connected on the outer peripheries of the two baffles and at the ends away from each other of the two baffle rings, and the sealing rings abut against the peripheral side walls of the sliding cavity, and a cavity is opened between the connector and the fixed block, and the cavity is located at the upper end part of the circular disk, and a liquid detector is arranged in the cavity.

[0006] The beneficial effects of the utility model are:

[0007] By setting the chamfer at the outer end of the baffle ring, the flow rate of water between the two baffle rings is high, which can ensure that the baffle ring fits the upper and lower side walls of the through cavity, and the baffle ring arranged in an annular manner on the baffle plate makes the baffle ring fit the upper and lower side walls of the through cavity, thereby preliminarily realizing the sealing work for the water flow. The sealing effect is further improved by the sealing ring on the baffle plate, and the through cavity is blocked by two baffles. At the upper end of the disc, there is a cavity in the connecting body for leakage buffering, which can effectively prevent water from leaking from the pipe mouth. A liquid detector is provided at the upper end cavity of the disc to detect whether there is leakage between the baffle plate and the through cavity, thereby reminding the user to check and repair.

Two left-right symmetrical baffles 21 are fixedly provided at the lower end of the circular disk 15. A circular sliding cavity 19 is provided in the fixed block 16. The baffle 21 is slidably matched with the side wall of the sliding cavity 19. Two upper-lower symmetrical baffle rings 22 are fixedly connected on the outer periphery of the baffle 21 and located between the upper and lower side walls of the through cavity 20. The outer ends of the baffle rings 22 are chamfered. A sealing ring 23 is connected on the outer periphery of the two baffles 21 and located at the ends away from each other of the two baffle rings 22.
