Abstract
The utility model relates to a phosphorous removal pneumatic jet valve, belonging to the technical field of design and manufacturing of phosphorous removal pneumatic jet valves, and comprising upper and lower valve bodies, a piston cylinder arranged at the upper part of the lower valve body, wherein, the upper valve body is arranged at the upper part of the piston cylinder, a piston is arranged in the piston cylinder, and a valve core is connected with the piston. The phosphorous removal pneumatic jet valve leads the valve core to act as a piston rod and the valve core of the jet valve as the valve core is designed to be integrally combined with the piston, so that the height of the whole valve body is reduced to save space and manufacturing cost. The utility model is an ideal phosphorous removal pneumatic jet valve, which solves the problems of large occupied space, high manufacturing cost and non-compact structure of the existing products, and has the advantages of simple structure and artful design.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of dephosphorization gas control injection valve.
Background technique
At present, in industrial production, especially the gas control injection valve that in rolled plate dephosphorize by high pressure water system, uses of smelter, its cylinder portion is separated with the body cavity spool, make the whole injection valve position that takes up space too high, it is very complicated that structure seems, not only takes the space but also waste the production raw material, structure is not compact, the manufacture cost height.
Summary of the invention
The purpose of this utility model provides a kind of compact structure, and the gas control injection valve at the bottom of space and the manufacture cost is taken up an area of in saving, to separate the problem that existing product exists.
Structure of the present utility model is as shown in drawings: be made of upper valve body and following valve body.One piston cylinder is arranged at the top at following valve body.Upper valve body is arranged at the top at piston cylinder.Upper and lower valve body and piston cylinder are one by bolted on connection.One piston is arranged in piston cylinder.On piston, connect a spool.Bottom at spool has valve pocket, on the top of valve pocket guide pin bushing is once arranged.Valve core upper sleeve is adorned a lower clapboard below valve pocket.Top at spool has upper guide bush, has upper clapboard in the bottom of upper guide bush.In the bottom of upper clapboard one snap ring is arranged.Snap ring is once arranged in piston cylinder.Method of work of the present utility model is under the selector valve control of valve body outside, drives spool and moves up and down.Finish switch motion.Valve pocket on the spool and guide pin bushing play the leading role of valve core movement.The utility model makes spool both play the effect of piston rod owing to piston rod is designed to spool and piston becomes one, and plays the effect of injection valve spool again.Make whole valve body shorten height, not only saved the space but also reduced manufacture cost.It is a kind of desirable dephosphorization gas control injection valve.It is simple in structure, designs ingenious.
