Abstract
The invention relates to a gas self-closing valve, with simple structure, easy installation and high reliability. The gas self-closing valve comprises a valve body which is respectively provided with an air inlet and an air outlet; the upper end of the air inlet is provided with a valve hole; the valve body is internally provided with a pulling rod which extends out of a valve cover and is connected with a leather film; the leather film divides the valve body into an upper part and a lower part, wherein, the lower part is a valve chamber; the leather film is connected with a movable iron sheet; a permanent magnet is arranged below the movable iron sheet; the permanent magnet is connected with a control rod; one end of the control rod is connected with a seal valve pad which is corresponding to the valve hole in the facing direction; and a fixed iron sheet which is fixed with the valve body is arranged below the permanent magnet.
Description
One, technical field:
The present invention relates to a kind of valve, especially relate to a kind of gas self-closing valve that is used for gas pipeline.
Two, background technique:
In the background technique, existing gas self-closing valve complex structure is installed difficulty, the cost height, and speed of response is slow, and closure effect is not good, and poor reliability easily causes potential safety hazard.
Three, summary of the invention:
The present invention provides a kind of gas self-closing valve in order to solve the deficiency in the above-mentioned background technology, and it is simple in structure, and the reliability height easily is installed.
For achieving the above object, the technical solution used in the present invention is:
A kind of gas self-closing valve, comprise valve body, be respectively arranged with suction port and air outlet on the valve body, it is characterized in that: be provided with valve port in the suction port upper end, be provided with the pull bar that stretches out valve gap in the valve body, pull bar is connected with epithelium, epithelium is divided into two-part up and down with valve body, lower half portion is a valve chamber, epithelium is connected with movable iron plate, and movable iron plate below is provided with permanent magnet, and permanent magnet is connected with controlling rod, controlling rod one end is connected with the sealing valve pad corresponding with the valve port forward, and the permanent magnet below is provided with the fixed iron piece of fixedlying connected with valve body.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
The present invention can be at air pressure under low excessively, the under-voltage and ultrahigh pressure situation effectively, the quick-make valve, simple in structure, have only a valve port, safe and reliable, easy to use, the reliability height has improved the Security that combustion gas is used greatly.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention;
Among the figure, the 1-valve body, the 2-valve gap, the 3-pull bar, the 4-epithelium, the 5-permanent magnet, the 6-fixed iron piece, the 7-valve chamber, the 8-controlling rod, the 9-suction port, the 10-valve port, 11-seals valve pad, the movable iron plate of 12-, 13-air outlet.
Five, embodiment:
Referring to Fig. 1, the present invention includes valve body 1, be respectively arranged with suction port 9 and air outlet 13 on the valve body 1, be stamped valve gap 2 on the valve body 1, be provided with valve port 10 in suction port 9 upper ends, be provided with the pull bar 3 that stretches out valve gap 2 in the valve body 1, pull bar 3 is connected with epithelium 4, and epithelium 4 two ends are fixed on the valve body 1, and epithelium 4 is divided into not connected two-part up and down with valve body, lower half portion is a valve chamber 7, epithelium 4 is connected with movable iron plate 12, and movable iron plate 12 belows are provided with permanent magnet 5, and permanent magnet 5 is connected with controlling rod 8, controlling rod 8 one ends are connected with the sealing valve pad 11 corresponding with valve port 10 forwards, and permanent magnet 5 belows are provided with the fixed iron piece 6 of fixedlying connected with valve body 1.
During real work, during proper functioning,, under the effect of suction between movable iron plate 12 and the permanent magnet 5, drive controlling rod 8 and valve port 10 is opened, make the stable output of gas with sealing valve pad 11 because effect epithelium 4 pressurizeds of air pressure are heaved.Because the suction between movable iron plate 12 and the permanent magnet 5 is greater than the suction between fixed iron piece 6 and the permanent magnet 5, so valve port 10 is kept open mode.Air pressure is crossed when low or under-voltage, because the pressure that epithelium 4 bears is less than the suction between fixed iron piece 6 and the permanent magnet 5, so under the effect of the suction between fixed iron piece 6 and the permanent magnet 5, drive controlling rod 8 and seal valve pad 11 close port 10.When ultrahigh pressure, because the pressure that epithelium 4 bears is greater than the suction between permanent magnet 5 and the movable iron plate 12, make epithelium 4 separate with controlling rod 8, this moment is because the effect of suction between permanent magnet 5 and the fixed iron piece 6 drives controlling rod 8 and sealing valve pad 11 close port 10.
