Description
Technical field
The utility model relates to a kind of hemispheric gas bag sealing laying-off valve, the quick laying-off valve of particularly a kind of hemispheric gas bag sealing coal dust.
Background technique
At present, the sealing means of existing valve mainly adopts mechanical sealing on the market, promptly mainly by the precision-fit between sealing surface or by flashboard carving of valve seat is made a concerted effort to keep the valve body sealing or is adopted flexible barrier materials such as nylon, teflon and rubber to keep sealing.But during owing to frequent unlatching of this type of valve and closure, the easy friction, Stamping Steel Ribbon, seal ring that the feasible flexible barrier materials such as nylon, teflon and rubber that adopted are made are prone to leakage.And the precision-fit between the mechanical sealing surface also the abrasion error can occur after repeatedly opening closure, makes the valve tightness descend.
Summary of the invention
The purpose of this utility model is to provide the sealing of a kind of employing gas bag, good seal performance, open and close is quick, reliability is high, the blanking quick laying-off valve of hemispheric gas bag sealing coal dust easily.
The utility model is by the valve body import, upper flange, the sealing hemisphere face, ring-type pressurising gas seal member, valve outlet and lower flange are formed, ring-type pressurising gas seal member bottom is a circumferential collar, described circumferential collar is provided with the O-ring seal that inside has the U-loop groove, the seal ring that has annular groove in the U-loop groove of described O-ring seal inside bottom being embedded with embeds ring, seal ring embeds the top of ring and leaves an annular pass that is used to inflate, the annular pass is provided with the access port that charges into gas on one side, and seal ring embeds the inner connection top annular passage of some importing gases and the passage of bottom annular groove of being provided with of ring.
Sealing hemisphere face of the present utility model is positioned at the middle part of valve body, and its top is provided with ring-type pressurising gas seal member, between pressurising gas seal member and the sealing hemisphere face uniform gap is arranged.
In order to strengthen the tightness of the utility model self, circumferential collar of the present utility model top is provided with annular contract mouth, is provided with therebetween to keep bubble-tight annular sealing strip between circumferential collar and the setting O-ring seal thereon.
Seal ring of the present utility model embeds inner being provided with along equally distributed 16 of girth of ring and is used to import the connection top annular passage of gas and the passage of bottom annular groove.
The utility model is owing to adopt pressurized gas compressing silicone rubber O-ring, thereby make seal ring be close to the structure that the sealing hemisphere face reaches sealing, make that the utility model sealability is good, and under nonexpondable situation, still can keep better seal, reliability height, of many uses.
The utility model is described in further detail below in conjunction with accompanying drawing:
