This ball valve adopts the screwed pipe to link to each other with the pipeline, simple to operate, and among the opening and closing process, sealing performance is high, and the security performance is better, but wide application in the natural gas, heating system, municipal pipeline transformation, reform transform on old city management way.
Description
Technical field
This utility model relates to a kind of ball valve, is specifically related to one and is applied to natural gas, heating system, the threaded weld access valve of municipal administration pipeline transformation.
Background technology
Fast development along with urban renewal, natural gas line, heating system, a large amount of layings of heating system, the demand of controlled valve is more come, especially demand and prescription thereof to ball valve is more and more higher, the ball valve of prior art is in welding and package assembly thereof, standard is the highest, during for needing bearing pressure bigger pipeline, security performance is the highest, and prior art ball valve, the moment that switch closes needs is bigger, operation inconvenience, and the sealing property of the ball valve of prior art is the highest, when installing connecting line, sealing property is the highest, security performance is the highest.
Therefore, necessary on the basis of prior art, a kind of reasonable in design of design research and development, switching manipulation is convenient, installation connecting line is convenient, and sealing is high, can be widely applied to natural gas, heating system, municipal administration pipeline transformation, the welding ball valve of old city pipeline transformation etc..
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, R & D design one reasonable in design, switching manipulation is convenient, installation connecting line is convenient, sealing is high, can be widely applied to natural gas, heating system, municipal administration pipeline transformation, the threaded weld access valve of old city pipeline transformation etc..
Technical scheme: in order to realize object above, the technical scheme that this utility model is taked is as follows:
A kind of threaded weld access valve, it includes: valve body, it is welded on valve body left, the Thread valve pipe of right both sides, it is arranged on the spheroid of valve inner, inside described Thread valve pipe, near ball position, seal receptacle is installed, sphere installation is on seal receptacle, near ball position, support ring is installed on seal receptacle, butterfly spring and packing ring it is sequentially installed with outside described support ring, described spheroid top connects valve rod, stem outer circumference is provided with valve stem sleeve, described valve stem top has been connected by screw hands handle, described valve stem sleeve top is provided with sealing gland, the junction, top of described valve rod and valve stem sleeve is provided with packing ring and O RunddichtringO, the junction, bottom of described valve rod and valve stem sleeve is provided with packing ring.
