Description
Technical field
Valve mounting technique field is the utility model is related to, more particularly to a kind of taper thread connecting length collocation structure.
Background technology
In compressor set design, the gas circuit of compressor, oil circuit and water route etc. are generally controlled by valve and sensor,
Therefore, the installation of a large amount of valves is related in the pipeline of compressor, and taper thread is the connected mode being commonly used, due to cone
The attribute of screw thread, screwing length are not certain, and it is influenceed very greatly, to cause to connect by accuracy of screw machining and dimensional uniformity
Line size can not be consistent with design afterwards.Conventional solution is first to install valve in erecting yard, then goes to survey
Take measurements, be finally processed again, even if in this way, also wanting repeated multiple times just can guarantee that correct installation dimension, especially more
Valve group is installed simultaneously in the case that, change number becomes more, both have impact on pipeline assembling is attractive in appearance and assembling progress, also increase
Assembly cost, the influence to high-volume order are more obvious.
Utility model content
To solve the above problems, the utility model provides a kind of taper thread connecting length collocation structure, meet valve and pipe
The connection request in road, improve efficiency of assembling.
To achieve the above object, taper thread connecting length collocation structure of the present utility model, the company for valve and pipeline
Connect, including the first pipe joint and the second pipe joint, one end of first pipe joint are provided with what is be connected with the valve
Taper thread, the other end are provided with straight thread；One end of second pipe joint be provided with the straight thread be connected in
Screw thread, the other end are connected with the pipeline.
Preferably, locking nut is additionally provided with first pipe joint, the locking nut connects with the straight thread screw thread
Connect.
Preferably, it is provided with gasket seal between the locking nut and second pipe joint.
Preferably, the inner surface setting of second pipe joint has the screw-in for the straight thread to first pipe joint
Depth carries out spacing interior step.
Preferably, it is respectively arranged with hexagonal boss on first pipe joint and the second pipe joint.
Preferably, second pipe joint is connected with the pipeline by anchor ear.
Taper thread connecting length collocation structure of the present utility model, adjust the straight thread and the second pipe of first pipe joint
The screwing length of the internal thread of joint compensates the rigging error of whole pipeline, meets different connection length between valve and pipeline
The installation requirement of degree, the uniformity of valve group installation dimension is ensure that, improves efficiency of assembling, be fully able to meet compressed air system
The installation requirements on road under the overall leadership.
Brief description of the drawings
Referring to the drawings, disclosure of the present utility model will be apparent.It is to be appreciated that these accompanying drawings are only schematic
, it is not drawn on scale and is also not intended to limit the scope of the utility model.In figure：
Fig. 1 is the schematic diagram of taper thread connecting length collocation structure of the present utility model；
Fig. 2 is that taper thread connecting length collocation structure of the present utility model is used for the schematic diagram that valve is connected with pipeline.
Embodiment
Specific embodiment of the present utility model is explained with reference to the accompanying drawings.
As illustrated in fig. 1 and 2, taper thread connecting length collocation structure of the present utility model, for valve 100 and pipeline 200
Connection, including the first pipe joint 1 and the second pipe joint 4, one end of first pipe joint 1 be provided with and the valve 100
The taper thread 11 of mating connection, the other end are provided with straight thread 13；One end of second pipe joint 4 is provided with and the straight spiral shell
The internal thread 43 that line 13 connects, the other end are connected with the pipeline 200.First pipe joint 1 and the second pipe joint 4 pass through straight thread
13 and internal thread 43 threaded connection screwing length, the connecting length between the valve 100 and pipeline 200 can be adjusted,
So as to compensate the rigging error between the valve 100 and pipeline 200.
Second pipe joint 4 can be designed to different types of attachment as needed from the connection of the pipeline 200, than
Such as conventional threaded connection, flange connection, welding, in embodiment of the present utility model, second pipe joint 4 and institute
Pipeline 200 is stated to connect by anchor ear 201.Connected for convenience of using anchor ear 201, fluted 44 set on second pipe joint 4,
For coordinating with the anchor ear 201.
The inner surface setting of second pipe joint 4 has deep for the screw-in of the straight thread 13 to first pipe joint 1
Degree carries out spacing interior step 41, and straight thread 13 can be prevented excessively to be screwed into, so as to ensure to adjust length.
Hexagonal boss 12,42 is respectively arranged with the pipe joint 4 of first pipe joint 1 and second, can facilitate and pacify in pipeline
Spanner operation is used when dress and length adjustment.
Locking nut 2 is additionally provided with first pipe joint 1, the locking nut 2 is threadedly coupled with the straight thread 13,
After length adjustment is completed, locking nut 2 is rotated to the end with second pipe joint 4 and is close to so as to lock, can be prevented
Pipeline loosens.Preferably, gasket seal 3, gasket seal 3 are provided between the locking nut 2 and second pipe joint 4
It is installed between the pipe joint 4 of locking nut 2 and second, it is ensured that connected between the pipe joint 4 of the first pipe joint 1 and second
Sealing.
Using taper thread connecting length collocation structure of the present utility model, when the connecting length of valve 100 and pipeline 200 needs
When adjusting, the screwing length of the internal thread 43 of the pipe joint 4 of straight thread 13 and second by adjusting first pipe joint 1 come
The rigging error of whole pipeline is compensated, the length of adjustment can be confirmed according to length of pipe and cooperation number.As long as so root
Adjustment length is provided according to different thread sizes, can be achieved with the purpose of compensation, so as to ensure that all pipelines can be pre-machined, directly
Tipping is matched somebody with somebody, while also ensure that the uniformity of valve group installation dimension, improves efficiency of assembling, is fully able to meet compressed air system
The installation requirements on road under the overall leadership.
As described above, exemplary embodiments of the present utility model are described in detail referring to the drawings.Should
Work as understanding, the utility model, which is not intended to, makes these details to form the limitation to scope of protection of the utility model.Not
