Description
Technical field
The present invention relates to valve matched device field, is driven more particularly to a kind of valve pneumatic being used under more dust environments
Dynamic device.
Background technology
Pneumatic diaphragm control valve is a kind of regulation device in pneumatic unit combination instrument, is that production carry out process is adjusted automatically
One of important step in section system, it receives the output signal of regulation meter to close and Open valve, reached to pressure, temperature
The parameter such as degree, flow and liquid level automatically adjusts, can be widely applied to chemical industry, oil, metallurgy, electric power, light textile industry it is automatic
Regulation and remote control.With its application constantly expand, to its reliability requirement more and more higher.There are many valves
The area such as outdoor, special Beijing and Tianjin is installed on, often there is sandstorm, using existing valve pneumatic drive device, due to it
Anti-dust performance is poor, and the dust in air can be entered in the spring cavity of valve pneumatic drive device by passage, dust granule mill
Hinder diaphragm, cause diaphragm to damage.In the area of more sand and dust, when push rod bounces back, the dust on push rod can be brought into guide copper sleeve,
Guide copper sleeve is caused to damage, after particularly dust is embedded in softer copper sheathing, push rod can be worn, cause the damage that copper sheathing is bigger,
Even push rod occurs killing phenomenon with guide copper sleeve.Therefore it is badly in need of designing and developing the valve pneumatic driving with efficient dustproof performance
Device, to meet to use under more dust environments.
The content of the invention
The present invention solves the technical problem of a kind of valve pneumatic drive device being used under more dust environments is provided, have
Efficient anti-dust performance, performance is reliable, service life length.
In order to solve the above technical problems, one aspect of the present invention is：One kind is provided and is used for more dust environments
Under valve pneumatic drive device, including：Pneumatic diaphragm control valve executing agency, connection framework and push rod, the air bladder
Dust-proof silencer, the upper center processing of the connection framework are installed on the passage that the lower film of regulating-valve actuator covers
There is the guide holder with connection framework one, offer pilot hole in the middle part of the guide holder, the upper end of the push rod stretches to
It is fixedly connected in the pneumatic diaphragm control valve executing agency and with the pneumatic diaphragm control valve executing agency, the push rod
Lower end is connected by the pilot hole with valve rod.
In a preferred embodiment of the present invention, guide copper sleeve is installed in the pilot hole.
In a preferred embodiment of the present invention, it is coated with hard chrome wearing layer at the lower end guiding of the push rod.
In a preferred embodiment of the present invention, ZHM types are installed at the lower end guiding of the push rod and combine dust-proof poly- ammonia
Ester rubber seal.
In a preferred embodiment of the present invention, the ZHM types combine dust-proof polyurethane rubber seal circle positioned at guiding copper
The lower end tube port position of set.
The beneficial effects of the invention are as follows：The present invention is simple and reasonable, by pneumatic diaphragm control valve executing agency
Dust-proof silencer is installed on the passage of lower membrane cover, it is possible to prevente effectively from dust performs from passage into pneumatic diaphragm control valve
In mechanism, it is ensured that the use reliability of executing agency；Guide holder is set simultaneously, the lower end of push rod passes through the guiding in the middle part of guide holder
Hole, lubricating grease can be accommodated in the gap between push rod and pilot hole, reduce friction, improve product service life.
Brief description of the drawings
