That is to say, if the liquid leaks between the side wall 102 of the aforementioned main body 1 and the outer surface of the outer joint ring 121 of the pipe joint 12, it actually advances in a straight line, such as figure 2 In the direction of the arrow, there is no resistance. Therefore, the greater the flow pressure of the liquid in the pipeline, the greater the probability of the flow pressure attacking and destroying the O-ring. As long as the O-ring is aging, leakage will occur immediately Therefore, the user must pay attention to and replace the oil joint 1 or the O-ring in it at any time, and check whether the shell is loose from time to time, otherwise, once leakage occurs, it will cause damage and increase Cost of pipeline setup

Embodiment Construction
[0030] In this way, in order to fully understand the structural features of the present invention, it is now explained as follows based on the drawings of the specification:
[0031] The valve or joint structure of the present invention may be suitable for applications such as Figure 4 and 5 2 embodiments of the oil optional connector shown, such as Figure 7 The ball valve 2a embodiment shown or as Figure 8 An embodiment of a check valve 2c is shown. However, it is not limited to the use of the foregoing three embodiments, and all the joint components belonging to the liquid pipeline are applicable. The present invention is only explained by the foregoing three more general embodiments. The valve or joint structure of the present invention at least includes:
[0032] Body 20, where the oil is connected to 2 (such as Figure 4 and 5 Shown), ball valve 2a (e.g. Figure 7 Shown) or check valve 2c (as Figure 8 The body structure shown) is different, but the difference belongs to ...

The invention relates to a valve or connector structure. The valve or connector structure at least comprises a body, a casing and a pipe body connector, wherein a circulation hole is formed in the body, so that a liquid can flow through the inside of the body; a positioning wall surface is formed on the inner wall of the circulation hole of the body, and an inner combination surrounding part is formed at the outer side end of the positioning wall; an external thread part is formed in the body and combined with the casing in a fastening manner; internal threads are formed in the casing and combined with the external thread part of the body, and a clamping surrounding part is formed in the casing; and an outer combination surrounding part is formed in the pipe body connector and has an appropriate thickness, so that the outer combination surrounding part is matched with the clamping surrounding part. When the casing and the pipe body connector are combined into a whole of the body, the clamping surrounding part of the casing is used and clamped at the outer combination surrounding part of the pipe body connector; an inner combination surrounding part is formed in the front end of the outer combination surrounding part of the pipe body connector; and the inner combination surrounding part of the pipe body connector and the inner combination surrounding part of the body are combined, so that the body and the pipe body connector are stably combined, the body and the pipe body connector is guaranteed to be tightly combined and cannot shake, the casing can be prevented from being loosened, and liquid leakage is avoided.
Description
Technical field [0001] The present invention relates to a valve or joint structure, in particular to a wall setting on the inner wall of the circulation hole of the body of the oil-free joint, ball valve or check valve, and forming an inner joint ring on the outer end of the positioning wall , And then set the inner joint ring on the pipe body joint. In this way, the inner joint ring of the pipe body joint can be combined with the inner joint ring of the body, and the body and the pipe body joint can be more firmly combined. To ensure that the connection between the main body and the pipe body joint is free of gaps, never shake, and has the advantages of preventing the shell from loosening and avoiding liquid leakage. Background technique [0002] Existing valves or joints, such as figure 1 and 3 Shown is an oil-free connector 1, such as image 3 It is a kind of ball valve 1a, the aforementioned oil joint 1 or ball valve 1a contains: [0003] The body 10, of course, the body struc...
