Abstract
The utility model discloses a connector valve for fluid pipe, whose structure is that a connector valve for fluid pipe comprise a valve body, fluid outlet and inlet equipped on the valve body and a valve bar equipped inside the valve body, characterized in that the fluid outlet and inlet is equipped with a connecting pipe, the connecting pipe is equipped with a rotary connecting nut, and the connecting pipe is equipped with locating structure which limits the connecting nut to slide axially on the connecting pipe. The connector valve is manipulated simply when connecting with the end of the pipe, the comparative position between both is low, which can better adapt the actual equipping and manipulating demand.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of joint valve that being used on the fluid circuit connects different pipelines of being located at.
Background technique
Fluid is generally undertaken by 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 need to install some joint valves, 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 by flange with being connected generally of pipeline, and promptly at the end of pipeline welded flange, flange set on this flange and the joint valve achieves a fixed connection by 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, have certain requirement in the position that connects between the above two, this can make troubles in the install operation process of reality.
The model utility content
The purpose of this utility model is at the problems referred to above, provide a kind of simple in structure, easy for installation, pipeline and its when mounted between the two relative installation require low novel fluid pipe joint valve.
The purpose of this utility model can realize by following technical proposal: a kind of fluid circuit joint valve, comprise valve body, be located at fluid output and import on the valve body, be located at the valve rod in the valve body, it is characterized in that, outlet or inlet at fluid are provided with connecting tube, connecting tube is provided with rotating coupling nut, and connecting tube is provided with restriction coupling nut limit structure in axial sliding in connecting tube.This fluid circuit joint valve is when assembling with pipeline, need be provided with the externally threaded coupling head that has that matches with above-mentioned coupling nut in the end of pipeline, when realizing being connected between joint valve and the pipeline, the turn coupling nut makes coupling nut be with externally threaded coupling head to match with described.In order to guarantee both sealings after connecting, between the end of coupling head end and described connecting tube, also need to be provided with sealing gasket.
In this fluid circuit joint valve, described limit structure is to be located at the position limiting convex ring connecting tube end and that outwards protrude, inwardly is provided with convex shoulder on coupling nut.Position limiting convex ring is by stopping that convex shoulder limits coupling nut and skids off connecting tube.
In this fluid circuit joint valve, the exterior edge face of described position limiting convex ring is provided with the boss of ring-type.This boss after coupling nut is tightened in the coupling head, can roof pressure on the set seal ring in described coupling head and connecting tube end, make seal ring generation deformation, to increase sealing effect.
In this fluid circuit joint valve, described position limiting convex ring and connecting tube are connected as a single entity.Position limiting convex ring generally can make distortion back, connecting tube end form by the mode of punch process.
In this fluid circuit joint valve, described valve body is provided with the liquid feeding mouth that communicates with its inside.Added some lubricated wet goods liquid in the valve body by the liquid feeding mouth in the past.
Compared with prior art, the beneficial effects of the utility model are:
1, this joint valve is provided with coupling nut, and this coupling nut can be threaded with set coupling head on the pipeline end and realize fixedlying connected between pipeline and the joint valve, and attended operation is convenient between joint valve and the pipeline.
2, do not need to be provided with flange, this joint valve is simple in structure, when being connected with pipeline, has saved the contraposition to set hole on the flange, and is easy to operate.
3, 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.
Description of drawings
Fig. 1 is the structural representation of this fluid circuit joint valve;
Fig. 2 is the component scatter diagram of this fluid circuit joint valve.
Embodiment
See Fig. 1, Fig. 2, the structure of this fluid circuit joint valve comprises valve body 3, be located at valve pipe 1 and the coupling nut 11 on the valve body 3 and be located at valve rod 2 in the valve body 3.Be provided with the import and the outlet of fluid on valve body 3, described coupling nut 11 can be arranged on this import or export place.
Described coupling nut 11 is connected on the valve body 3 by a connecting tube 10, and an end of this connecting tube 10 is fixedly connected on the valve body 3 by the mode of welding.The other end of connecting tube 10 is provided with the ring-type position limiting convex ring 101 that protrudes its outer side surface, and inwardly is provided with the convex shoulder of a ring-type on the coupling nut 11 close end faces of connecting tube 10 1 sides.Coupling nut 11 is socketed in the connecting tube 10 with gap, and described position limiting convex ring 101 can be by stopping that described convex shoulder limits coupling nut 11 and slides in connecting tube 10.Coupling nut 11 is provided with internal thread, its can be located at the pipeline end and have externally threaded coupling head and be threaded.For the sealing after realizing this joint valve and pipeline being connected, between the end of described coupling head and connecting tube 10, also need be provided with sealing gasket.On the exterior edge face of described connecting tube 10, also be provided with an annular boss 102 that protrudes, when this joint valve is connected with the pipeline end, this annular boss 102 can be pressed on the sealing gasket, thereby make the sealing pad produce a certain amount of distortion, and then the sealing after helping improving this joint valve and pipeline being connected.Described position limiting convex ring 101 is formed in one with connecting tube 10, and position limiting convex ring 101 generally is that end by connecting tube 10 is through stamping forming.
Above-mentioned valve rod 2 passes valve body 3, and the outside of the extended valve body 3 of an end.In order to realize the sealing between valve rod 2 and the valve body 3, by interior Packing seat 6, filler 7, the filler screw 8 of being provided with successively outward, filler 7 is generally made by Expanded graphite in a side of valve body 3 the above valve rod 2 external part, and filler screw 8 is threaded on the valve body 3.After the preparation of this joint valve was finished, a cap 9 also can be threaded on valve body 3.
In the using process of reality, also need in valve body 3, to inject liquid sometimes as lubricant oil and so on, on valve body 3, also be provided with the liquid feeding mouth 5 that can communicate with valve body 3 inside, be connected with one silently 4 in the outside screw of liquid feeding mouth 5.
