The model utility content
The purpose of this utility model is at above-mentioned deficiency, provides a kind of simple in structure, and cost is low, and is easy to use, safe and reliable automatic closed control valve.
The technological scheme that realizes the utility model purpose is:
This automatic closed control valve can be made of with the tubular valve body that pipeline flexibly connects two ends, and characteristics are to be provided with billiard table shape piston in valve body, are fixedly connected with the taper valve port on the valve body below piston; The piston rod of piston upper end and be fixedly connected between the garland on the valve body and be provided with piston spring; Be connected with the escapement that contains metal on the valve body of the billiard table place correspondence of piston, be provided with the escapement spring between escapement and the valve body; The outside at valve body is provided with controlling magnet.
Good seal when making billiard table shape piston fall in the taper valve port, the bulb diameter of billiard table shape piston and the tapering of taper valve port are complementary.
In order to make billiard table shape piston up and down flexible operation, non-migration, accurately in valve body, on the valve body of piston rod correspondence, be fixedly connected with guide ring.
Can control escapement accurately in order to make controlling magnet, can take different control methods and structure, for example can on controlling magnet, be provided with pull bar, pull bar passes the pilot hole on 2 guide plates that are located at the valve body outside, on pull bar, be provided with locating stud, make controlling magnet up and down, and can accurately be parked in the outside at escapement place along the valve body outside; Also can be provided with the sign that shows the escapement position on valve outer wall, the people is the sign place that controlling magnet is moved to or leave the escapement position; Or adopt other controlling method and structure.
The utility model is simple in structure, can select spare parts in common use such as raw material such as existing plastics and spring, magnet for use, and adopts conventional processes to make, and implements easily.
During work, valve body is serially connected on the supply channel.When the pipeline normal water supply, hold the escapement that contains metal with controlling magnet and leave billiard table shape piston, the thrust that overcomes piston spring under pressure that supplies water and floating function is opened the taper valve port with billiard table shape piston jack-up, and water flows through valve body smoothly; After water flow through valve body smoothly, controlling magnet was mentioned or is left the escapement position, and the metal escapement is upspring under the escapement spring action; When pipeline stops to supply water when losing the pressure of water supply, the thrust of piston spring is pushed billiard table shape piston to the taper valve port at once, the sealing intake tunnel, and meanwhile the metal escapement is upspring under the effect of escapement spring, and is stuck in the billiard table place of billiard table shape piston; When pipeline once more during normal water supply, because the effect of metal escapement makes billiard table shape piston can not leave the taper valve port, thereby seals supply channel effectively, the phenomenon that can not occur again metalling run out takes place.Supply water if desired,, make controlling magnet hold the metal escapement and leave billiard table shape piston, can resume water supply again as long as controlling magnet is moved to place, escapement position.
The utility model enforcement simple in structure, easy, cost is low, easy to use, be quick on the draw, safe and reliable, solved effectively because the water tap of cutting off the water when being in open mode, suddenly the water resource waste problem that causes of water.This automatic closed control valve also can be applicable to and carries other flowing mediums, in the pipeline as oil, industrial chemicals etc., prevents evaporating, emitting, dripping or leaking of liquid or gas.Can be used for each family, also applicable to public places such as school, factory, station, offices, application area is very extensive, has practical and popularizing value.
