Problems solved by technology
[0005] The purpose of the present invention is to provide a detachable filter structure for marine hydraulic valves to solve the problem that the existing filter screens are generally installed inside the valve body, and a large amount of sundries will be produced during the long-term use of the valve body. The surface of the filter screen is clogged, and it usually sticks to the surface of the filter screen during long-term use. During maintenance, it is necessary to remove the valve body, and then take out the protective screen inside the valve body to clean the protective screen, which will cause trouble in the use and maintenance of the valve body. Causes long downtime of the valve body

The invention discloses a marine hydraulic valve detachable filtering structure. The marine hydraulic valve detachable filtering structure comprises a hand wheel and a hydraulic control cylinder, the hydraulic control cylinder is arranged at the bottom end of the hand wheel, a transmission shaft is arranged at the bottom end of the hydraulic control cylinder, a valve body is arranged at the bottom end of the transmission shaft, and a water outlet is formed in the rear end of the valve body. When a filter screen needs to be installed, a filter screen sealing ring is aligned to the interior of a fixing groove, then a screw penetrates through fixing holes of fixing blocks of the filter screen and a water inlet, the fixing ring is placed on the surface of the screw, then a stress application rod is inserted into a fixing ring, the filter screen and the water inlet are fastened by the fixing ring through the stress application rod, and tight connection between the water inlet and the filter screen is guaranteed; and when the filter screen needs to be cleaned and maintained, the screw is taken down, the filter screen can be pulled out and cleaned, the filter screen can be rapidly installed without dismantling the valve body, it is guaranteed that the hydraulic valve can be continuously and normally used, and compared with a traditional hydraulic valve, the hydraulic valve can be rapidly maintained.
Description
technical field [0001] The invention belongs to the technical field related to hydraulic valves, and in particular relates to a detachable filter structure for marine hydraulic valves. Background technique [0002] The marine hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with the electromagnetic pressure distribution valve. It can be used to remotely control the on-off of the oil, gas and water pipeline system of the hydropower station. Commonly used in clamping, control, lubrication and other oil circuits. There are direct-acting type and pilot-operated type, multi-purpose pilot-operated type, components used to control liquid pressure, flow and direction in hydraulic transmission, among which the control pressure is called, the control pressure is called, and the control on-off and pressure is called The function of the hydraulic control valve (...
