Hydraulic valve with liquid level being convenient to observe

Abstract

The invention discloses a hydraulic valve with the liquid level being convenient to observe. The hydraulic valve comprises a valve body, a flashboard, wedges, observing frames, supporting rods, a valve cover, a threaded rod, a rotary disc and a valve hole, wherein connecting flanges are fixedly connected to the two ends of the valve body correspondingly; mounting holes are formed in the positions,close to the edges, of the connecting flanges; the rotary disc is fixedly connected to the top end of the threaded rod; the flashboard is in threaded connection with the periphery of the lower end ofthe threaded rod; a hole is formed in the flashboard; a seal board is fixedly connected to the middle of the interior of the valve hole; a rubber seal ring is fixedly connected to the upper surface of the seal board; the observing frames are fixedly connected to the positions, on the two sides of the valve hole, of the valve body correspondingly; the wedges are connected to the positions, close to the lower ends, of the interiors of the observing frames in a sleeved mode; the supporting rods are fixedly connected to the upper surfaces of the wedges; and the top ends of the supporting rods penetrate through the upper surfaces of the observing frames. The observing frames are fixedly connected to the positions, on the two sides of the valve hole, of the valve body, the wedges are connectedto the lower ends of the interiors of the observing frames in a sleeved mode, and the supporting rods are fixedly connected to the two sides of the top ends of the wedges correspondingly, so that theindexes of the water levels on the two sides of the valve body are more conveniently observed during usage.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a hydraulic valve for convenient observation of liquid levels. Background technique [0002] The hydraulic control valve is a valve controlled by water pressure. The hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes, functions and places, it can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc. A filter should be installed before the hydraulic control valve, and it should be convenient for sewage discharge. This type of valve should generally be installed horizontally in the pipeline. The prior art has many defects such as: [0003] Due to the defects of the structure of the existing technology in the ...

AI Technical Summary

Problems solved by technology

[0003] Due to the defects of the structure of the existing technology in the early stage, it is difficult to observe the water level inside the valve body, and it is difficult to control the water flow when it is used, so it cannot meet the needs of the existing technology.

[0004] In the prior art, the gates of the valves in use have the effect of blocking and sealing, but the weight of the gate itself is too large, which makes it very troublesome to operate, so it cannot meet the requirements of the prior art. need
