Abstract
The utility model relates to a phosphorous removal pneumatic control lowest liquid level valve, which belongs to the technical field of designing and manufacturing lowest liquid level valves. The phosphorous removal pneumatic control lowest liquid level valve is composed of a valve body and an upper cover. A valve seat is arranged in the valve body, and a valve core is arranged on the valve seat. The lower portion of the valve body is provided with a cylinder jacket, and a piston is arranged in the cylinder jacket. The piston is provided with a piston rod. The bottom of the valve body is provided with a lower valve pocket. One side of the cylinder is provided with a change-over valve. The phosphorous removal pneumatic control lowest liquid level valve is an important component in a rolled sheet steel high pressure water phosphorous removing system. The phosphorous removal pneumatic control lowest liquid level valve is installed between an accumulator and a pump, and an air supply is connected with the change-over valve. The phosphorous removal pneumatic control lowest liquid level valve has simple structure and rational design. Since the cylinder is provided, pneumatic control is realized. A hydraulic control system is saved. Actions become rapid and sensitive. Once a main pipe is broken or decompressed in the system due to other reasons, the valve can be closed instantly, and other accidents can be prevented. The phosphorous removal pneumatic control lowest liquid level valve has simple structure and rational design, and is an ideal lowest liquid level valve.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of minimum level valve.
Background technique
The minimum level valve that uses in metallurgical industry rolled plate dephosphorize by high pressure water system at present is hydraulic control minimum level valve.The structure of this hydraulic operated valve is comparatively complicated, and action sensitivity is poor.In addition, it is the power with hydraulic pressure, needs equipment such as configuration hydraulic station, and manufacture cost is very high.Use hydraulic oil to waste energy again.The equipment failure rate height, thus influence is produced.Therefore say that the present minimum level valve that surges in use is not very desirable.
Summary of the invention
The purpose of this utility model provides a kind of low cost of manufacture, corollary equipment is simple and sensitive minimum level valve reliably, to solve the practical problem that existing product exists.
Structure of the present utility model is as shown in drawings: be made of valve body and loam cake.On the top of valve body one loam cake is arranged.One valve seat is arranged in valve body, have spool on the valve seat, between spool and valve gap, have spring.On the top of spool one upper valve sleeve is arranged.There is a copper sheathing upper valve sleeve inboard.Bottom at valve body has cylinder liner, and a piston is arranged in the cylinder liner.Have piston rod on the piston.In the valve body bottom one lower valve sleeve is arranged.Lower valve sleeve is connect with valve body mutually by bolt.On a side of cylinder, have selector valve.The utility model is the vitals in the rolled plate dephosphorize by high pressure water system.Be installed between accumulator and the pump, source of the gas is connected with selector valve.Its method of work is: air enters cylinder, promotes piston and piston rod drive spool and moves up and down.Finish the connection of medium and block.Last lower valve sleeve plays guiding to piston rod.Spring plays the effect of accumulation of energy compression.The utility model is simple in structure, and is reasonable in design, owing to have cylinder, realizes pneumatic control.So action is quick sensitive.When in case be responsible for break or because of the other reasons system in decompression, can instantaneously close, prevent the generation of other accidents.The utility model is simple in structure, and is reasonable in design.It is a kind of desirable minimum level valve.
