Abstract
A pneumatic plunger valve comprises a valve body. The valve body is provided with a valve. Valve cores are arranged in the valve body. The valve cores comprise a fixed valve core and a movable valve core. The fixed valve core is arranged at one end of the valve body. The movable valve core is of an annular hollow structure and is connected with an air cylinder. Under the action of the air cylinder, the movable valve core can move to enable the valve to be opened or closed. According to the pneumatic plunger valve, the movable valve core is of the hollow structure, so that the weight of the valve core is reduced; when the valve is closed, the air cylinder only needs to overcome the resistance, applied by media, on the annular section of the movable valve core, so that the diameter of the air cylinder can be greatly reduced. Consequently, the overall size of the valve body can be greatly reduced, reaction time is short, structure is simple, and cost is low.
Description
Technical field
The utility model belongs to hydrodynamic pressure pipeline technical field, relates to a kind of pneumatic plunger valve.
Background technique
Along with the development of industrial automation technology, need some equipment can adapt to the requirement of this development, the far distance automatic controlling of hydrodynamic pressure, needs one of problem solving exactly.
At present, the far distance automatic controlling of existing hydrodynamic pressure, adopts the less of pneumatic control, simultaneously, existing pneumatic control valve all exists cylinder volume excessive, pneumatic control power deficiency, and valve latus rectum is little, the problems such as the reaction time is long, selling at exorbitant prices, are restricting development and the application of pneumatic control valve.
Model utility content
The purpose of this utility model is to provide a kind of pneumatic plunger valve, has solved the cylinder volume existing in prior art excessive, the problem that the reaction time is long.
The technical solution of the utility model is, pneumatic plunger valve, comprise valve body, valve body is provided with valve, in valve body, be provided with spool, spool comprises fixed spool and movable spool, and fixed spool is arranged on one end of valve body, movable spool is annular hollow-core construction and is connected with cylinder, and under the effect of cylinder, movable spool is removable makes valve open or closes.
Feature of the present utility model is also:
The two ends of fixed spool connect by a valve rod, and one end of fixed spool is fixed on valve body, and the other end is socketed on moving valve in-core.
Movable spool is connected by flange with cylinder, and joint is provided with vent.
Between fixed spool and valve body, be provided with o RunddichtringO, between fixed spool and movable spool, be provided with Yx RunddichtringO.
Between movable spool exterior side wall and valve inner sidewall, be provided with Yx RunddichtringO, between movable spool end and valve interior wall, be provided with o RunddichtringO.
The utlity model has following beneficial effect:
1, the movable spool of the utility model is hollow-core construction, significantly alleviated the weight of spool, when valve closing, cylinder only need to overcome medium and be applied to the resistance on movable spool circular crosssection, therefore the cylinder diameter of cylinder can significantly reduce, thereby valve overall volume is greatly reduced, and the reaction time shortens.
2, the utility model is simple in structure, and cost is low.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Pneumatic plunger valve, referring to Fig. 1, Fig. 2 and Fig. 3, comprise valve body 1, valve body 1 is provided with valve, in valve body 1, be provided with spool, spool comprises fixed spool 2 and movable spool 3, and fixed spool 2 is arranged on one end of valve body 1, movable spool 3 is for annular hollow-core construction and be connected with cylinder 4, and under the effect of cylinder 4, movable spool 3 is removable makes valve open or closes.
Referring to Fig. 4, the two ends of fixed spool 2 connect by a valve rod 5, and one end of fixed spool 2 is fixed on valve body 1, and the other end is socketed in movable spool 3.
Between fixed spool 2 and valve body 1, be provided with o RunddichtringO 6, between fixed spool 2 and movable spool 3, be provided with Yx RunddichtringO 7.
Between movable spool 3 exterior side wall and valve inner sidewall, be provided with Yx RunddichtringO 7, between movable spool 3 ends and valve body 1 inwall, be provided with o RunddichtringO 6.
The utility model pneumatic plunger valve, the flow direction of fluid can be optional.During valve open, referring to Fig. 1, fluid can be smoothly via extremely outlet of import.When cylinder 4 piston rods are released, movable spool 3 is pushed forward, and the import of fluid and outlet are intercepted by movable spool 4 and o RunddichtringO 2, valve is in partition state, referring to Fig. 2, movable spool 3 compresses the o RunddichtringO on valve body 1, can prevent that valve closing is not tight.One end and cylinder assembly flange that movable spool 3 is connected with cylinder 4 are provided with vent, are beneficial to movable spool 3 flexible movements.
Between movable spool 3 and fixed spool 2, Yx RunddichtringO is installed, can prevents that dielectric leakage from arriving movable spool 3 inner chambers and the left chamber of valve body.Between fixed spool 2 and valve body 1, o RunddichtringO is housed, after this pneumatic plunger valve is connected with piping flange, o RunddichtringO is compacted, can prevent medium leakage.
