Abstract

The invention discloses a hydraulic drainage valve capable of being driven and controlled hydraulically through relatively small pressure. The hydraulic drainage valve is formed by installing a cavity, a piston, a pipe body M, a pipe body L, an exhaust pipe body, a water inlet pipe body, a switch valve inserting groove and a switch valve. When the hydraulic drainage valve needs to be opened, a switch handle is lifted to enable the piston to move upwards, a water valve water inlet hole is connected with a water tank water outlet port, so that a water valve is opened to realize drainage; when the hydraulic drainage valve needs to be closed, the switch handle is pushed downwards to enable the piston to move downwards, when the piston moves to the bottom end, the water valve water inlet hole is disconnected with the water tank water outlet port, so that the water valve is closed.

Description

technical field [0001] The invention relates to a drain valve device that can be driven and controlled by hydraulic pressure, especially a drain valve that can be driven and controlled by low pressure. Background technique [0002] At present, the drain valve of a large pool is subjected to huge pressure of water, so that the traditional water valve needs a lot of force to open or close the water valve when draining, making the drive control of the drain valve laborious and slow in response. Contents of the invention [0003] In order to overcome the disadvantage that the traditional drain valve is difficult to open and close after being subjected to high water pressure, the present invention provides a hydraulic drain valve, which can control the opening and closing of the drain valve under the hydraulic drive of a small pressure. [0004] The technical solution adopted by the present invention to solve the technical problem is: install the cavity of the hydraulic drain v...
