Abstract
This invention relates to inflatable sealed brake valve, which comprises gas cylinder, valve elements and control elements, wherein, the valve elements board is connected to the piston bar; the valve has symmetrical two parts with medium channel located. It is characterized by the following: the two parts medium channel sealed place are located with one ring concaved groove each; the ring concaved grooves are located with ring fixed ring and rubber sealed ring; the ring fixed ring is located in the bottom of the ring concaved groove and the rubber sealed ring is covered on the ring fixed ring outside; the ring fixed ring is located with gas channel connected to the control elements through gas holes and tubes.
Description
Technical field
The invention belongs to a kind of gate valve, be specifically related to a kind of gate valve that is used for switch mass transport passage in strength conveying solid substance particle or the powder model system that is installed in.
Background technique
Above-mentioned air-transport system has usability widely, is mainly used in the conveying of various materials, and hermetically sealed in the process of pneumatic transmission, nothing is leaked, and can be used for the mass transport of industries such as thermoelectricity, cement, chemical industry, plastics, grain and food.For example the heat power plant boiler flying dust generally adopts pneumatic conveying method to deliver to grey storehouse after capturing.Before the present invention made, prior art used the gas-filled type valve that is used for switch mass transport passage in strength conveying solid substance particle or powder model system to mainly contain butterfly valve class, ball valve class etc.Because the particularity of air-transport system working environment, there are defective respectively in existing gas-filled type butterfly valve and ball valve.
The butterfly valve class is because sealing pair all is positioned at transfer passage, be subjected to directly washing away of course of conveying high speed moving medium particle, sealing pair will soon lose efficacy because of wearing and tearing, so working life is very short, only be several months even tens days general working life, causes the whole system cisco unity malfunction.
The ball valve class is because the relation of structure exists the manufacturing assembly precision to require height, repair demolition trouble, the disadvantage that working life is short.
Summary of the invention
The object of the present invention is to provide a kind of gas-filled type dual face seals gate valve; this valve not only can substitute existing gas-filled type butterfly valve and ball valve is installed and used in strength conveying solid substance particle or powder model system; be used for switch mass transport passage; and the advantage with good seal performance has been filled up the blank of inflatable seal gate valve.
For achieving the above object, the present invention has adopted following technological scheme: mainly by cylinder, control unit, this gas-filled type dual face seals gate valve that valve component constitutes, valve plate in the valve component links to each other with piston rod, valve body divides left and right sides two-part of symmetry, valve body is provided with medium channel, its main points are: valve body medium channel sealing part respectively is provided with an annular groove in the left and right sides, be equipped with annular retainer ring and rubber seal in the annular groove respectively, the annular retainer ring is positioned at the annular groove bottom, rubber seal is nested with in annular retainer ring periphery, be provided with gas-entered passageway on annular retainer ring, gas-entered passageway is through inlet hole, suction tude communicates with the control unit transfer port.
The present invention's beneficial effect compared with prior art is: what butterfly valve class and ball valve class gas-filled type valve adopted is the form of single rubber seal sealing, sealing station is respectively a periphery or one-sided, exists respectively to be subject to that conveying material washes away or the dissatisfactory defective of sealing effect.The present invention is owing to adopted the technological means of dual face seals, the rubber seal of two inflations tightly is pressed in the valve plate both sides, inflation pressure is greater than line transportation pressure, form two sealings seal band very reliably, therefore the sealability of valve is fabulous in having the FLUID TRANSPORTATION of solid particle, is zero leakage.
Description of drawings
Accompanying drawing is the utility model embodiment broken section structural representation.
Embodiment
With gate valve shown in this case accompanying drawing 1 is embodiment.Mainly by cylinder 1, control unit 2, this gas-filled type dual face seals gate valve that valve component constitutes, valve plate 6 tops in the valve component link to each other with piston rod (among the figure draw in the end), 3 fens bilateral symmetry two-part of valve body, valve body 3 is provided with medium channel, its main points are: valve body medium channel sealing part respectively is provided with an annular groove in the left and right sides, be equipped with annular retainer ring 5 and rubber seal 4 in the annular groove respectively, annular retainer ring 5 is positioned at the annular groove bottom, and fasten by screw threads, rubber seal 4 is nested with in annular retainer ring 5 peripheries, be provided with gas-entered passageway on annular retainer ring 5, gas-entered passageway is through inlet hole 7, suction tude (among the figure draw in the end) communicates with the transfer port of control unit 2.Control unit 2 is made up of several pneumatic control function modules such as selector valve, regulators, external control signal is controlled valve event by it, control unit 2 links to each other with control signal and source of the gas, and control signal is by the open and close of control unit 2 control valves and the inflation and the exhaust of rubber seal 4 inside.
During work, during valve closing valve plate 6 move to two rubber seal 4 behind the position, the rubber seal 4 of two inflations tightly is pressed on two sides of valve plate 6, because inflation pressure is greater than line transportation pressure, formed two sealings seal band very reliably, therefore the sealability of valve is fabulous in having the FLUID TRANSPORTATION of solid particle, is zero leakage; When valve opening, valve plate 6 returns to valve pocket inside (piston rod drives on the valve plate 6 and moves), and two rubber seal 4 are shunk again under not having the inflation pressure situation and return in the protection groove.Under above-mentioned state, two rubber seal 4 and valve plate 6 not in the fluid passage, therefore, fluid by the time, wash away less than rubber seal 4 and valve plate 6, thereby protected sealing pair, prolonged the working life of valve.
