Longer, the bodily form and weight are larger.Application of the gate valve on pipeline is very extensive, suitable for being manufactured into large bore valves.Gate valve is generally used
In blocking fluid, regulation flow should not be used in.Because when gate valve is in half-open position, flashboard can by fluid erosion and impact and
Sealing surface is destroyed, can also produce vibration and noise.
Gate valve in the market, it includes valve body, bonnet, valve element, valve rod and handwheel with entrance point and the port of export,
Wherein entrance point and the port of export use hickey, when the entrance end of external pipe and gate valve connects, pass through raw material first
Band winding entrance point or the port of export, then external pipe and entrance end are tightened, because pipeline is nondirectional length, revolving
It is arduously time-consuming to turn rundown process, installation is inconvenient.
The content of the invention
The purpose of this utility model be to provide it is a kind of simple in construction, can with the silk that pipeline is quickly connected is outspoken connects lock
Valve.
The utility model is achieved through the following technical solutions：Silk is outspoken to connect gate valve, including valve body, and valve body is provided with entrance point
And the port of export；Bonnet, the bonnet are fixed on valve body；Valve rod, valve rod pass through the bonnet；Handwheel, positioned at the upper end of valve rod；
Valve element, positioned at the lower end of valve rod；The entrance point and the port of export at least one end are provided with quick connection structure, and the quick connection structure includes
Speed nut, rubber seal, plastic spacer, the speed nut is interior to have end face and internal thread, the rubber seal
It is arranged in valve body import end or the port of export, the speed nut is tightened with valve body import end or the port of export by hickey,
The plastic spacer is arranged between rubber seal bottom and speed nut end face.
Further, the footpath mouth of rubber seal described in the utility model tapers into from lower to upper.
Further, rubber seal cross section described in the utility model is taper.
Further, the bottom of rubber seal described in the utility model is provided with the flange part of outwardly convex.
Further, the inwall of entrance point and the port of export described in the utility model is inclined plane, the inclined plane and taper rubber
The outside fitting of glue sealing ring.
The utility model compared with prior art, has advantages below and beneficial effect：The utility model uses and connects spiral shell soon
Cap quickly connects the entrance end of the pipeline in the external world and valve body, and by rubber seal rings for seal, while coordinate plastic mattress
Piece plays speed nut rundown process, prevents rubber seal from and then rotating, and improves the sealing effectiveness after connection, has installation side
Just, the set-up time is saved, improves operating efficiency.
