Abstract
The utility model provides a mining gas butterfly valve which comprises a valve body, a valve rod, a valve plate, a rubber seal and an electric actuator. The valve rod and the valve plate are arranged in the valve body. The valve rod is fixedly connected with the valve plate as a whole. The top end of the valve rod is connected with the electric actuator which is a mining flame-proof type valve electric actuator. The rubber seal is a fluorine rubber seal, and is fixed on the valve plate. The mining gas butterfly valve is controlled automatically, has the advantages of anticorrosion, static electricity proof, being less prone to aging, double-directional pressure bearing and double-directional sealing.
Description
Technical field
The utility model relates to valve field, refers to the special-purpose butterfly valve of a kind of gas in mine especially.
Background technique
Existing reed valve generally adopts rubber seal or metal hard-sealing.The caulking gum of rubber seal butterfly valve is easily aging, and anti-corrosive properties are poor, and easily produce static; And metal hard-sealing butterfly valve collides the generation spark easily when switch valve.The high corrosion in the gas place, under the high explosion environment, all there is potential safety hazard in these defectives.Existing gas valve is generally Hand-operated butterfly valve because of security needs, can't realize automation control.
The model utility content
The utility model proposes a kind of gas in mine butterfly valve, solved the automation control of can't realizing of the prior art, and the high corrosion in the gas place, under the high explosion environment, there is the problem of potential safety hazard.
The technical solution of the utility model is achieved in that a kind of gas in mine butterfly valve, comprise valve body, valve rod, valve plate, rubber seal and Electric actuator, described valve rod and valve plate place in the valve body, described valve rod and valve plate are connected to one, the top of described valve rod is connected with Electric actuator, and described Electric actuator is the flame-proof mine electric device for valve; Described rubber seal is the fluorine rubber sealing, and described rubber seal is fixed on the valve plate.
Comprise that further also be provided with filler between described valve body and the valve rod, described filler places the joint of valve rod and Electric actuator.
Comprise that further described valve rod and valve plate are connected to one by pin.
Comprise that further described valve body and valve plate are to be made by spheroidal graphite cast iron, described valve rod is to be made by stainless steel.
Beneficial effect: the utility model has solved the defective that exists in the background technique, is modified to fluorine rubber sealing by the sealing that will have now, makes the special-purpose butterfly valve of gas have corrosion protection, antistatic, is difficult for aging, bidirectional bearing, advantage such as two way sealed.Be equipped with the flame-proof mine electric device for valve again, solved the needs of valve automation control.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is an embodiment's of the utility model structural representation;
Wherein: 1, valve body; 2, valve rod; 3, valve plate; 4, rubber seal; 5, filler; 6, Electric actuator; 7, pin.
Embodiment
As shown in Figure 1, a kind of gas in mine butterfly valve comprises valve body 1, valve rod 2, valve plate 3, rubber seal 4, filler 5, Electric actuator 6, pin 7; Wherein Electric actuator 6 is the flame-proof mine electric device for valve, and rubber seal 4 is fluorine rubber sealings.
The fluorine rubber sealing is adopted in the sealing of the special-purpose dish valve of gas in mine, possesses anticorrosion, antistatic, is difficult for aging, bidirectional bearing, characteristics such as two way sealed; And being equipped with the flame-proof mine electric device for valve, the flame-proof mine electric device for valve of configuration has solved the demand of valve automation control.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
