Abstract
The utility model provides a pipeline connector valve, which comprises a valve body, a valve rod, a valve pipe, a connecting pipe and a connecting nut. The valve body is provided with an inlet and an outlet of fluid, the valve rod is arranged in the valve body, the valve pipe is connected at the outside of the valve body, one end of the connecting pipe is fixedly connected with the valve body, and the other end of the connecting pipe is connected to the connecting nut. A limit convex ring protruding out of the outer side of the connecting pipe is arranged at one end of the connecting pipe connected with the connecting nut, and an annular inward protruding shoulder is arranged on the end face on one side of the connecting nut close to the connecting pipe. The pipeline connector valve can be fixed with a pipeline in threaded connection, and the connection between the connector valve and the pipeline is convenient to operate. A flange is not needed, thereby omitting aligning to a hole arranged on the flange and being convenient to operate during connection with the pipeline. The connection between the connector valve and the pipeline is achieved, and simultaneously the relative position between the connector valve and the pipeline is not required as long as the end portion of the pipeline can reach the position of the connecting nut, thereby facilitating connecting operation in practical process.
Description
Technical field
The utility model relates to the pipe joint valve.
Background technique
Fluid generally carries out through pipeline in the process of transmission; Some than the complex pipeline system in; As in the transfer conduit system of cooling liquid in the refrigeration industry, all some joint valves need be installed; Increase the Security of pipe-line system on the one hand, also made things convenient for the connection between the pipeline on the other hand.When existing joint valve was installed on the pipeline, it connected through flange with being connected generally of pipeline, i.e. the welded flange in the end of pipeline, and flange set on this flange and the joint valve achieves a fixed connection through clamping bolt.This Placement has its defective in the installation process of reality, at first, and complex structure, fitting operation difficulty; Secondly, owing on two flanges, be respectively equipped with the hole of mutual correspondence, the number in set hole can be not too many on each flange; The contrapositions in hole when mounted of two flanges require high, and after pipeline and joint valve linked together, relative position between the two had certain narrow limitation; Therefore; Realize being connected between pipeline and the joint valve, higher at the status requirement that connects between the above two, this can make troubles in the install operation process of reality.
Summary of the invention
The utility model technical problem to be solved is: a kind of pipe joint valve is provided, and it is simple in structure, easy for installation, can solve the problem that exists in the above-mentioned background technology.
The technological scheme that the utility model technical solution problem is adopted is: it comprises valve body, valve rod, valve pipe, connecting tube and coupling nut; Said valve body is provided with the import and the outlet of fluid; Said valve rod is located in the valve body; Said valve pipe is connected the valve body outside, and said connecting tube one end is fixedly connected with said valve body, and the other end connects said coupling nut; Said connecting tube is provided with the position limiting convex ring of its outer side surface of protrusion at this end that connects with said coupling nut; Said coupling nut is enclosed within the said connecting tube with gap, and said coupling nut is provided with inside ring-type convex shoulder on the side end face near said connecting tube.
When adopting technique scheme, the utility model also can adopt or combined is used following technological scheme:
Said connecting tube is provided with annular boss on its exterior edge face.
Said valve body is provided with the liquid feeding mouth, and said liquid feeding mouth is inner to be connected with said valve inner.
The beneficial effect of the utility model is: set coupling nut on the pipe joint valve that the utility model provided, can be connected with the form fix that is threaded with pipeline, and attended operation is convenient between joint valve and the pipeline; And the pipe joint valve arrangement of the utility model is simple, need not be provided with flange, when being connected with pipeline, has saved the contraposition to set hole on the flange, and is easy to operate.When realizing being connected between joint valve and the pipeline, as long as the end of pipeline can arrive the position of coupling nut, between the two relative position is not required, made things convenient for the attended operation in the real process.

Embodiment
With reference to accompanying drawing 1,2.
The utility model comprises valve body 1, valve rod 2, valve pipe 3, connecting tube 4 and coupling nut 5.Valve body 1 is provided with the import and the outlet of fluid, and valve rod 2 is in the valve body 1, and valve pipe 3 is connected valve body 1 outside, and an end of connecting tube 4 is fixedly connected with valve body 1, and the other end connects coupling nut 5; Connecting tube 4 is provided with the position limiting convex ring 41 that protrudes its outer side surface at this end that connects with coupling nut 5, and coupling nut 5 is enclosed within the connecting tube 4 with gap, and coupling nut 5 is provided with inside ring-type convex shoulder 51 on the side end face near connecting tube 4.
Connecting tube 4 can be fixedly connected on the valve body 1 through the mode of welding.Position limiting convex ring 41 fuses with connecting tube 4, and position limiting convex ring 41 can be processed through impact briquetting by the end of connecting tube 4.
The exterior edge face of connecting tube 4 is provided with annular boss 42, in the outside of annular boss 42 sealing gasket can be set.When being connected with exterior line, annular boss 42 can be pressed on the sealing gasket, and makes sealing gasket produce a certain amount of distortion, the sealing after helping improving this joint valve and pipeline being connected.
In the present embodiment, coupling nut 5 is socketed in the connecting tube 4 with gap, and the position limiting convex ring 41 in the connecting tube 4 can contact and block ring-type convex shoulder 51 with the ring-type convex shoulder 51 of coupling nut 5, thus the slip of restriction coupling nut 5 in connecting tube 4.On the coupling nut 5 internal thread is arranged, can be connected with the coupling head that externally threaded exterior line is arranged.
Valve rod 2 is located in the valve body 1, and an end of valve rod 2 outside that can stretch out valve body 1.In order to ensure the sealing between valve rod 2 and the valve body 1, the connection part of valve rod 2 and valve body 1 is by interior Packing seat 7, filler 8, the filler screw 9 of being provided with successively outward, and filler 8 is generally processed by Expanded graphite, and filler screw 9 is threaded on the valve body 1.After the pipe joint valve assembling of the utility model is accomplished, also can on valve body 1, install cap 10 additional, cap 10 is threaded with valve body 1.
