Therefore, need to provide a kind of equipment that can solve the asynchronous interchange issues of same specification valve installation size.
Model utility content
For prior art above shortcomings, the purpose of this utility model is to solve the one or more problems that exist in above-mentioned prior art.
For example, one of the utility model object is to provide a kind of and can solves in the different interchange issues of same specification valve installation size, realizes the equipment of the object that shortens the replacing time and reduce labor intensity.
The utility model provides a kind of thread type creeping flange.Described thread type creeping flange comprises the first flange plate, the second flange plate, the first telescopic pipe, the second telescopic pipe and connecting tube, and wherein, the first telescopic pipe has the one end being fixed on the first flange plate, and the other end being threaded with connecting tube; The second telescopic pipe has the one end being fixed on the second flange plate, and the other end being threaded with connecting tube; By described, be threaded, can make described the first flange plate and the second flange plate move axially along the center line of described screw thread.
According to thread type creeping flange of the present utility model embodiment, the outer circumferential face of the other end of the other end of described the first telescopic pipe and described the second telescopic pipe is provided with outside thread, and the inner peripheral surface of described connecting tube is provided with the internal thread coordinating with described outside thread.
According to thread type creeping flange of the present utility model embodiment, the helix direction of circling of described the first telescopic pipe and the second telescopic pipe is contrary.
According to thread type creeping flange of the present utility model embodiment, described screw thread is sealed pipe screw thread.
Thread type creeping flange of the present utility model can be realized the exchange of different installation dimension (length) valves of same specification, to pipeline, do not need cutting (or lengthening) to process, be conducive to shorten the replacing time, reduce labor intensity, and there is the features such as simple in structure, exchange is convenient; Can also be by controlling sealed pipe thread tolerance, select unlike material, the wall thickness of change the first telescopic pipe, the second telescopic pipe and connecting tube etc. is applicable on various pressure pipings it.
Accompanying drawing explanation
By the description of carrying out below in conjunction with accompanying drawing, above and other object of the present utility model and feature will become apparent, wherein:
Fig. 1 shows according to the schematic diagram of the first flange plate of the utility model exemplary embodiment and the first telescopic pipe and the second flange plate and the second telescopic pipe cooperating structure.
Fig. 2 shows according to the sectional view of the connecting tube of the utility model exemplary embodiment.
Fig. 3 shows according to the sectional view of the thread type creeping flange of the utility model exemplary embodiment assembling condition when changing valve.
Fig. 4 is the side view of Fig. 3.
Description of reference numerals is as follows:
1, the first flange plate 2, the second flange plate 3, the first telescopic pipe 4, the second telescopic pipe 5, connecting tube 5-1, right-handed thread 5-2, left-handed thread 5-3, tool withdrawal groove.
Embodiment
Hereinafter, in connection with exemplary embodiment, describe thread type creeping flange of the present utility model in detail.
Fig. 1 is according to the schematic diagram of the first flange plate of the utility model exemplary embodiment and the first telescopic pipe and the second flange plate and the second telescopic pipe cooperating structure.Fig. 2 is according to the sectional view of the connecting tube of the utility model exemplary embodiment.Fig. 3 is according to the sectional view of the thread type creeping flange of the utility model exemplary embodiment assembling condition when changing valve.Fig. 4 is the side view of Fig. 3.As shown in Figures 1 to 4, thread type creeping flange of the present utility model comprises the first flange plate 1, the second flange plate 2, the first telescopic pipe 3, the second telescopic pipe 4 and connecting tube 5.
Wherein, one end of the first telescopic pipe 3 is fixed on the first flange plate 1, and the outer circumferential face of its other end is provided with outside thread and described outside thread is right-handed thread.One end of the second telescopic pipe 4 is fixed on the second flange plate 2, and the outer circumferential face of its other end is provided with outside thread and described outside thread is left-handed thread.The inner peripheral surface of connecting tube 5 is provided with internal thread, and the internal thread of connecting tube is divided into two sections, one section of internal thread is wherein the right-handed thread 5-1 coordinating with described the first telescopic pipe 3 outside threads, another section of internal thread is the left-handed thread 5-2 coordinating with the second telescopic pipe outside thread, and is provided with tool withdrawal groove 5-3 in the joint of described two sections of internal thread 5-1,5-2.The first telescopic pipe 3 and the second telescopic pipe 4 are threaded with connecting tube according to corresponding rotation direction, and described the first telescopic pipe and the second telescopic pipe move forward and backward by rotation in connecting tube, thereby the first flange plate 1 and the second flange plate 2 can be moved axially along the center line of described screw thread.
While using thread type creeping flange of the present utility model, the first flange plate 1 is connected with pipeline with one of them in the second flange plate 2, another is connected with valve, when replacing valve runs into installation dimension (length) difference, can be by the pipe 5 that is rotatably connected, allow the first telescopic pipe 3 and the second telescopic pipe 4 precession or back-out in connecting tube, it is free-extension, thereby reach the object that regulates the distance between the first flange plate 1 and the second flange plate 2, realization is not cutting to pipeline the exchange that completes the different length of installation valves of same specification in the situation that (or lengthening) processing.In addition, when adjustment is installed, flange moves vertically, can guarantee that the flange connecting screw hole being connected with valve does not deflect.
