Abstract

The invention discloses a hydraulic time delay valve. The hydraulic time delay valve comprises a pressing cap, a valve cover, a valve body, a cylinder cover, a piston with a connecting rod, a time delay ball, a cylinder barrel with an upper opening, a seat plate, a pressure spring, a sealing cover, a valve element assembly, a reset spring and a bottom cover, wherein the cylinder cover and the cylinder barrel are arranged in an oil pressure device cavity, an upper cavity of the cylinder cover extends out of the oil pressure device cavity, the pressure spring matches with a circular flange and the sealing cover, the valve rod is in sliding fit and liquid sealing with a valve rod hole of the sealing cover, the valve cover screws external threads of an oil pressure device cavity of the valve body, the upper cavity is in sliding fit with the valve cover, the two ends of the seat plate are embedded into clamping grooves in the upper end of the valve body, the piston divides the cylinder barrel into an upper oil storage cavity and a lower hydraulic oil cavity, and an internal thread seat of the pressing cap screws external threads of the upper cavity. Hydraulic time delay is formed by thecylinder barrel, the piston and the cylinder cover, water pressure time delay is formed by a movable seat and a bottom water pressure cavity, the delay time does not affected by water quality, and the delay time is long, and the service life is long.

Description

technical field [0001] The invention relates to a hydraulic delay valve. Background technique [0002] At present, in the existing technology, most of the time-delay spool springs on the market are controlled by water, and the time of delay is affected by the water quality, so that its service life is not long and it is easy to fail. The utility new technology is a kind of liquid control time-delay valve designed for the time-delay valve not to be affected by water quality. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic time-delay valve, which has the characteristics of not being affected by water quality, stable time and long service life. [0004] The present invention is achieved in this way: a hydraulic time-delay valve, which is special in that it includes a pressing cap, a valve cover, a valve body, a cylinder cover, a piston with a connecting rod, a time-delay ball, a cylinder with an upper opening, Seat plate, pr...
