Description
Technical field
The present invention relates to a kind of Pneumatic two-position two-way fluid control valve, belong to valve field.
Background technique
Bi-bit bi-pass fluid control valve is widely used in industry manufacturing, Service Industrys such as washing, light industry, food, medical treatment, be to carry neutral gas or liquid, as the final controlling element of circulation mediums such as air, water, washing agent, be modern industry gas, fluid is controlled indispensable product.
Making service industry, using flowing medium in large quantities---air, water, water vapor etc. go to carry out powered, and material mixes and stirs, work such as material cleaning, and the running of these needs of work timings, quantitative fixed cycle.Traditional bi-bit bi-pass fluid control valve is manual operation, is unfavorable for realizing integrated automation control.
In addition, traditional bi-bit bi-pass fluid control valve is opened and closed and is carried out the controlling component formation by valve body, valve seal parts.The valve seal parts rely on the action of keying execution controlling component, and valve body is carried out the controlling component employing with keying and is threaded, and the valve seal parts adopt screw and nut to be connected with the keying power unit.Wherein opening and closing the cylinder body of carrying out controlling component is with metal.Its shortcoming is that metal cylinder barrel forms with machining, and is too heavy, and quality is difficult for guaranteeing.
Summary of the invention
The purpose of this invention is to provide a kind of light and handy bi-bit bi-pass fluid control valve that can realize automation control attractive in appearance.
In order to achieve the above object, technological scheme of the present invention has provided a kind of Pneumatic two-position two-way fluid control valve, by bi-bit bi-pass formula valve body, valve seal parts and keying are carried out controlling component and are formed, it is characterized in that described keying execution controlling component is by joint, piston, spacer, be provided with the cylinder barrel that pressurized gas is imported and exported, valve rod, pad, handle and spring are formed, cylinder barrel is fixedlyed connected with bi-bit bi-pass formula valve body by joint, valve rod is located at cylinder barrel and joint middle part, its end that is exposed at the cylinder barrel outside is fixedlyed connected with handle, an end of being located in the bi-bit bi-pass formula valve body is connected with the valve seal parts, be provided with pad in the cylinder barrel from top to bottom successively, spring and piston, seal between joint and the bi-bit bi-pass formula valve body, be all sealing between valve rod and cylinder barrel and the joint, piston and valve rod fixed seal connection, and contact with inner wall of cylinder sealing, spacer is fixed on the piston and with valve stem seal and contacts.
Described cylinder barrel is to be made by the engineering plastics mold pressing.
Described pressurized gas is imported and exported to be preferably and is had two, is located at the both sides up and down of cylinder barrel respectively.
The present invention adopts the bi-bit bi-pass form, be divided into normally closed, often open two kinds.When equipment control cabinet sends signal, the pilot pressure source of the gas enters keying of the present invention and carries out controlling component, the valve seal parts are opened (or closing), beginning conveyance fluid (or block fluid) treats that FLUID TRANSPORTATION finishes, control cabinet sends signal blocker pilot pressure source of the gas once more and flows into this product keying execution controlling component, the valve seal parts are closed (or unlatching), and medium fluid is blocked (or conveying), and (or conveying) stops to flow.
The present invention has the following advantages:
1. adopting air is power source, takes conveniently, pollution-free;
2. lightly attractive in appearance;
3. may command multitube road circulation.
