Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, and particularly relates to a pressure gauge pipeline connection assembly. Background Art
[0002] Water pipes are usually used to circulate media. In order to know the pressure of the media flowing in the water pipes, pressure gauge equipment is usually required. The pressure gauge can clearly understand the pressure value of the media flowing in the pipeline and display it through a pointer.
[0003] First, select the installation position. If the installation position is between two water pipes, the two pipelines can be directly connected through a tee fitting, and then the pressure gauge is installed on the top of the tee. When the media in the pipeline flows into the tee fitting, the pressure gauge can detect the pressure value of the media flowing in the tee.
[0004] If the pipeline at the installation position is integral, the pipeline needs to be cut open through a cutting tool, and then the two cut ends are connected through a tee fitting. And as described above, the pressure gauge is installed on the third end of the tee fitting.
[0005] In summary, the tee pipe, as a commonly used part for installing a pressure gauge for detecting the medium pressure between water pipes, is widely used. In order to achieve the effect of quick installation, some quick-connect components have also appeared on the market for quick installation between the end of the pipeline and the end of the tee.
[0006] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: Most of the connection components are assembled by means of threaded connection, and the end contact surface is sealed by adding a sealing rubber ring to increase the sealing performance. However, the impact force generated by the media flowing in the pipeline will cause the pipeline to vibrate. Especially in some common and civilian fields such as sprinkler water pipes and tap water pipes, the pipelines are mostly made of PVC material, and its fixing property is relatively poor. The vibration impacts the pipeline, increasing the amplitude of the pipeline shaking. And the shaking will cause the threaded connection to often become loose. Once the threaded connection is not tight, the extrusion force between the end of the tee and the pipeline will gradually decrease, and the sealing performance will also be greatly reduced. Once the sealing performance is reduced, the media will flow out from the gap. And the shaking plus the water flow impacting the gap will cause the gap to become larger and larger, resulting in a vicious cycle. Over time, at least, the pressure gauge will detect the pressure of the media flowing inaccurately, and the connection needs to be manually tightened frequently. At worst, the end of the pipeline will be deformed and damaged, and then reinstallation is required. Content of the Utility Model
[0007] The main purpose of the utility model is to provide a pressure gauge pipeline connection assembly, which can effectively solve the problems in the background art.
[0008] To achieve the above object, the technical solution adopted by the utility model is as follows:
[0009] A pressure gauge pipeline connection assembly includes pipeline pipe fittings. The number of the pipeline pipe fittings is two. A tee joint is provided before the pipeline pipe fittings. Connection assemblies are provided at one end of each of the pipeline pipe fittings close to the tee joint. The tee joint includes a tee pipe. A pressure gauge is connected to the top of the tee pipe. External thread teeth are provided on the outer wall of the tee pipe at one end close to the pipeline pipe fittings. Three sleeve through-pieces I are fixed on the outer wall of the tee pipe on one side of the external thread teeth. The connection assembly includes a connection cylinder, a limit claw and a sealing rubber ring. A clamping cylinder is provided at one end of the connection cylinder away from the tee joint. Internal thread teeth are provided on the inner wall of the connection cylinder at one end away from the clamping cylinder. Sleeve through-pieces II are provided on the outer wall of the connection cylinder at the position of the sleeve through-pieces I. Long screws are provided between the parallel sleeve through-pieces I and sleeve through-pieces II. Limit nuts are threadedly connected to the outer walls at both ends of the long screws.
[0010] Preferably, the pipeline pipe fittings are respectively inserted into the inner parts of the closer ends of the tee pipe.
[0011] Preferably, the connection cylinder, the clamping cylinder, the limit claw and the sealing rubber ring are respectively sleeved on the outside of the pipeline pipe fittings.
[0012] Preferably, the sealing rubber ring is located between the limit claw and the tee pipe, and the closer ends of the tee pipe and the limit claw are respectively in contact with the sealing rubber ring.
[0013] Preferably, the connection cylinder is threadedly connected to the external thread teeth on the outside of the end of the tee pipe through the internal thread teeth on the inner wall.
[0014] Preferably, the long screws respectively penetrate through and communicate with the sleeve through-pieces I and sleeve through-pieces II with matching positions, and the two limit nuts on the outer wall of the long screw are respectively located at the mutually remote ends of the sleeve through-pieces I and sleeve through-pieces II.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] The pipeline pipe fittings and the tee joint are assembled and spliced through the connection assembly, and then used in combination with the long screws and the limit nuts to achieve the effect of secondary limitation. This limitation can provide a stable connection effect when the medium flows and vibrates, so that the connection part will not have the problem of thread loosening, increasing the smooth passing of the medium flow between the pipeline pipe fittings and the tee joint, making the pressure value detected by the pressure gauge more accurate, and at the same time avoiding the problem of frequent manual tightening, and having better practical effects.

Specific embodiments
[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] As Figures 1-4 shown, a pressure gauge pipeline connection component includes pipeline pipe fittings 1, the number of pipeline pipe fittings 1 is two, a tee fitting 2 is provided before the pipeline pipe fittings 1, connection components 4 are provided at one ends of the pipeline pipe fittings 1 close to the tee fitting 2, the tee fitting 2 includes a tee pipe 21, a pressure gauge 3 is connected to the top of the tee pipe 21, external thread teeth 22 are provided on the outer walls of the tee pipe 21 close to one ends of the pipeline pipe fittings 1, three sleeve penetrating parts one 23 are fixed on the outer walls of the tee pipe 21 on one side of the external thread teeth 22, the connection component 4 includes a connecting cylinder 41, a limit claw 42 and a sealing rubber ring 43, a clamping cylinder 411 is provided at one end of the connecting cylinder 41 away from the tee fitting 2, internal thread teeth 412 are provided on the inner wall of the connecting cylinder 41 away from the clamping cylinder 411, sleeve penetrating parts two 413 are provided on the outer walls of the connecting cylinder 41 at the positions of the sleeve penetrating parts one 23, long screws 5 are provided between the parallel sleeve penetrating parts one 23 and sleeve penetrating parts two 413, and limit nuts 6 are threadedly connected to the outer walls of both ends of the long screws 5.
[0024] Specifically, the pipeline pipe fittings 1 are respectively inserted into the interiors of the relatively close ends of the tee pipe 21.
[0025] Specifically, the connecting cylinder 41, the clamping cylinder 411, the limit claw 42 and the sealing rubber ring 43 are respectively sleeved on the outside of the pipeline pipe fittings 1.
[0026] Specifically, the sealing rubber ring 43 is located between the limiting claw 42 and the tee pipe 21, and the ends of the tee pipe 21 and the limiting claw 42 that are close to the sealing rubber ring 43 are in contact respectively, forming the sealing performance after connection.
[0027] Specifically, the connecting cylinder 41 is threadedly connected with the external thread teeth 22 at the end of the tee pipe 21 through the internal thread teeth 412 on the inner wall, forming the first limit fixation.
[0028] Specifically, the long screw 5 penetrates through the first sleeve penetrator 23 and the second sleeve penetrator 413 with matching positions respectively, and the two limit nuts 6 on the outer wall of the long screw 5 are located at the ends of the first sleeve penetrator 23 and the second sleeve penetrator 413 that are away from each other respectively, forming the second limit fixation and ensuring the sealing stability.
[0029] Working principle: The limiting claw 42, the connecting cylinder 41, the clamping cylinder 411, and the sealing rubber ring 43 are respectively sleeved on the outside of the pipeline fitting 1. Then, the pipeline fitting 1 is inserted into the inside of the end of the tee pipe 21. The connecting cylinder 41 moves towards the end close to the tee fitting 2 and squeezes the limiting claw 42 to make it wrap the outer wall of the pipeline fitting 1. Then, the connecting cylinder 41 is rotated, and it is threadedly connected with the external thread teeth 22 through the internal thread teeth 412. At this time, the end of the limiting claw 42 and the end of the tee pipe 21 squeeze the sealing rubber ring 43 and keep the connection sealed. After this step of connection is completed, the first limit fixation is formed. At this time, after the position of the second sleeve penetrator 413 matches the position of the first sleeve penetrator 23, the long screw 5 penetrates through the first sleeve penetrator 23 and the second sleeve penetrator 413 at the matching positions. Then, the two limit nuts 6 passing through them are respectively screwed, thereby forming the second limit fixation. When there is shaking, due to the anti-torsion property generated by the cooperation of the long screw 5, the limit nuts 6 with the first sleeve penetrator 23 and the second sleeve penetrator 413, the situation of thread loosening does not occur between the connecting cylinder 41 and the tee pipe 21, ensuring that the tee pipe 21 and the end of the limiting claw 42 can tightly clamp the sealing rubber ring 43 and ensuring the sealing stability.
