Abstract
The utility model discloses a pneumatic control valve, which comprises a cylinder and a value body with an interface. The plunger-typed valve clack is connected with the cylinder through the handspike, and a value core is arranged in the channel between two interfaces. The end surface of the valve clack is fixed with an airproof cushion, and the valve clack moves in the value body, which can press the airproof cushion on the value core for obstruction.
Description
Technical field
The utility model relates to a kind of pneumatic control valve.
Background technique
The traditional, pneumatic control valve utilizes the straight line motion driven gear bar of cylinder, makes circular movement by gear bar driven gear again, thereby drives the rotation of butterfly valve flap, realizes that pneumatic valve cuts out, the conversion of breakdown action.Because the seal rubber pad of flap and valve body often rotates friction, make the seal rubber pad wearing and tearing, cause and leak.And traditional, pneumatic valve arrangement complexity, driving component is many, and it is unreliable to work.
Summary of the invention
The purpose of this utility model is for a kind of simple in structure, reliable operation, the pneumatic control valve of long service life are provided.
Main technical schemes of the present utility model is: this pneumatic control valve comprises cylinder, has the valve body of interface, flap in the form of piston links to each other with cylinder by push rod, in the passage between two interfaces spool is housed, the flap end face is fixed with seal rubber pad, the motion of flap in valve body, seal rubber pad can be pressed on the spool, passage is cut off.
Be the plane contact sealing between flap and the spool in the utility model, drive the push rod straight line motion, flap is pressed on the spool, realize closing by cylinder.This plane sealing form good sealing effect of the present utility model, seal rubber pad is not frayed, through using for a long time, does not have weeping.The utility model driving component is few, reliable operation, and it is fast to realize opening and closing conversion, and installation, maintenance is convenient, as a kind of cut-off device, can be widely used in the fields such as plumbing, sewage, chemical industry, feed channel.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is an embodiment's of the utility model a structural representation;
Fig. 2 is another embodiment's of the utility model a structural representation.
Embodiment
Embodiment one
As shown in Figure 1, present embodiment is one two a ventilation brake control valve, have two interface A, B communicating on its valve body 2, flap 5 in the form of piston links to each other with cylinder 1 by push rod 4, cylinder 1 can promote push rod 4, flap 5 to-and-fro motion in valve body 2, and the end of an interface B is equipped with spool 6, and flap 5 lower end surfaces are fixed with sealing gasket 7, the motion of flap 5 in valve body 2 can be pressed on seal rubber pad 7 on the spool 6, and the passage between interface A, the B is cut off.
Embodiment two
As shown in Figure 2, present embodiment is a threeway pneumatic control valve, have three interface A, B, C that communicate on its valve body 2, wherein the end of two interface B, C all is equipped with spool 6, can to-and-fro motion in valve body 2 at the effect lower Disc 5 of cylinder 1, its upper and lower end face all is fixed with seal rubber pad 7, and the to-and-fro motion of flap 5 makes when the seal rubber pad 7 when flap 5 lower end surfaces is pressed on the spool of an interface B end, other two interface A, C connections; When the seal rubber pad 7 of flap 5 upper-end surfaces was pressed on the spool of another interface C end, other two interface A, B were communicated with.When present embodiment can be controlled a pipeline fluid and opens, another pipeline fluid was closed, and had saved semi-automatic-controlled electrical apparatus element for control automatically, reached the effect of a valve dual-purpose.Other structure of present embodiment is identical with embodiment one.
Claims (1)
1, a kind of pneumatic control valve, comprise cylinder (1), have the valve body (2) of interface, it is characterized in that: flap in the form of piston (5) links to each other with cylinder (1) by push rod (4), in the passage between two interfaces spool (6) is housed, flap (5) end face is fixed with seal rubber pad (7), the motion of flap (5) in valve body (2) can be pressed on seal rubber pad on the spool (6), makes common partition.
