Abstract
The invention provides a flat pneumatic four-way fluid control valve, which comprises a flat four-way valve body, a valve sealing component and an on-off control component. The invention is characterized in that the on-off control component consists of a front cover, a piston rod, a piston, a spacer, a cylinder barrel, a spring, a rear cover and a handle. The front cover and the rear cover are respectively connected with the front and the rear ends of the cylinder barrel in a sealing way; the front cover is provided with a compressed gas inlet and a compressed gas outlet communicated with the interior of the cylinder barrel, and is connected with the flat four-way valve body in a sealing way; the piston rod is arranged in the cylinder barrel, wherein, the end of the piston rod protruding out of the rear cover is provided with a handle, while the end in the flat four-way valve body is fixedly provided with the valve sealing component; the spring and the piston are arranged in sequence inside the cylinder barrel from up to down, wherein, the piston rod is sealed with the rear cover and the front cover; the piston is connected with the piston rod, and is connected with the interior wall of the cylinder barrel in a sealing way; the spacer is fixed on the piston and contacts with the piston rod in a sealing way. The invention has the advantages that air is adopted as the power source, therefore the power source can be easily accessed and is pollution-free; and the invention is capable of controlling the flow of a plurality of pipelines.
Description
Technical field
The present invention relates to a kind of Pneumatic plane four-way fluid control valve, belong to valve field.
Background technique
Plane four-way fluid control valve is widely used in industry manufacturing, Service Industrys such as washing, light industry, food, medical treatment, is to carry air, and the final controlling element of circulation mediums such as water is a modern industry gas, and fluid is controlled indispensable product.
Making service industry, use flowing medium-air, water, water vapor etc. in large quantities and gone to carry out powered, material mixes and stirs, work such as material cleaning, and the running of these needs of work timings, quantitative fixed cycle.Traditional plane four-way fluid control valve is the type hand valve, is made of valve body, valve and manual opening-closing device, and valve relies on the manual opening-closing device action, and valve body adopts with the manual opening-closing device and is threaded.Valve adopts screw and nut to be connected with the manual opening-closing device.Its shortcoming needs manual control, and inefficiency can not centralized control.
Summary of the invention
The purpose of this invention is to provide a kind of high working efficiency, can realize the plane four-way fluid control valve that automation is controlled.
In order to achieve the above object, technological scheme of the present invention has provided a kind of Pneumatic plane four-way fluid control valve, by plane four-way 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 protecgulum, piston rod, piston, spacer, cylinder barrel, spring, bonnet and handle are formed, protecgulum and bonnet are tightly connected with the cylinder barrel rear and front end respectively, before be covered with the pressurized gas that leads to cylinder barrel inside and import and export, and be connected with plane four-way formula valve seal, piston rod is located at the cylinder barrel middle part, its end that exposes bonnet is provided with handle, an end of being located in the plane four-way formula valve body is fixed with the valve seal parts, cylinder barrel inside is provided with spring and piston from top to bottom successively, be all sealing between piston rod and bonnet and the protecgulum, piston and piston rod fixed seal connection, and contact with inner wall of cylinder sealing, spacer is fixed on the piston and with rod seal and contacts.
Described bonnet inboard is provided with groove, and an end of described spring embeds in the described groove.
The present invention adopts the plane four-way form, be divided into normally closed, often open two kinds.When control cabinet sends signal, the pilot pressure source of the gas enters the keying implementation controller, open the valve seal parts, pipeline inner fluid medium begins to flow, and work finishes, and control cabinet sends signal once more, disconnect the pilot pressure source of the gas and enter the keying implementation controller, the valve seal parts are closed, the fluid that flows in the blocking-up pipeline, and a work cycle finishes.
The present invention has the following advantages:
1. adopting air is power source, takes conveniently, pollution-free;
2. may command multitube road circulation.
