Abstract
The utility model relates to a loose joint and plug stop type valve for fuel gas pipelines, which can control the on-off states of fuel gas in the fuel gas pipelines. A loose pipe 2 is sheathed and butted together with an inlet of a valve body 1 through a table 3, the loose pipe 2 and the valve body 1 are connected together by a hexagonal nut 9 through bayonet and screw thread, and the inlet part of the loose pipe 2 is provided with interconnect screw thread 5. In the utility model, a short pipe and an elbow pipe which are required in the original installation are removed, and interfaces at the loose pipe 2 are reduced, so that the external leakage of the fuel gas is reduced. The utility model has the advantages of material saving, fewer interfaces, convenient installation and operation, etc.
Description
The logical plug type check valve for gas pipeline that ends of control combustion gas in a kind of gas pipeline.
Gas pipeline in the past is connected the preceding bright valve that ends of traditional right-angle type that uses with table.Be connected and the logical effect that ends although this kind valve can play, because the place of connecing before it adopts fixed interface, connects the structure of short tube, Gu Er exist interface many, easily leak, materials take, by filling the shortcoming such as trouble.
Thereby the purpose of this utility model is to design a kind of novel valve that can reduce interface, be easy to install the minimizing materials.
Fig. 1 is a structural representation of the present utility model, also is that specification digest is with scheming.Each label is respectively among the figure: 1 valve body, and 2 live manages 3,4 cylindricals, 5 screw threads, 6 springs, 7 lids, 8 card circles, 9 hexagonal nuts, as shown in the figure, the utility model is made up of valve body 1, pipe 2 alive and hexagonal nuts 9, the pipe 2 of living is docking together by platform 3 and valve body 1 entrance suit, and is connected as a single entity by bayonet socket and screw thread with valve body 1 with the hexagonal nuts pipe 2 of will living, and there is interior even screw thread 5 pipe 2 porch of living.
When using the utility model, mode and gas meter that one termination is traditional join, in generation, have an end of the pipe 2 of living no longer to need to connect short tube, necessary accessory when using similar valve before the elbow etc., only need to have in original just generation externally threaded pipe joint directly to join by rotating the pipe 2 of living with the internal thread of the pipe 2 of living, and with hexagonal nuts the three is tightened to one and gets final product.
Claims (1)
1, the logical plug type check valve for gas pipeline that ends of control combustion gas in a kind of gas pipeline, formed by valve body 1, pipe 2 alive and hexagonal nuts 9, the pipe 2 that it is characterized in that living is docking together by platform 3 and valve body 1 entrance suit, and be connected as a single entity by bayonet socket and screw thread with valve body 1 with will live pipe 2 of hexagonal nuts 9, there is interior even screw thread 5 pipe 2 porch of living.
