Description

[0003] Traditional water hammer eliminators are independent of the pipes of the water supply system and cannot connect two independent pipes. The water hammer eliminator has only one water inlet joint, which is vertically installed on the pipe of the water supply system through the water inlet joint. Therefore, the pipe is used to convey water flow, and the water hammer eliminator is only used to eliminate the water hammer phenomenon.

[0023] The inner wall of the left adjusting washer 16 and the inner wall of the right adjusting washer 17 are both coplanar with the inner wall of the water pipe 11 .

[0026] An annular auxiliary sealing groove 26 is disposed on the inner wall of the connecting hole 15 ; an auxiliary sealing ring 27 is disposed in the auxiliary sealing groove 26 and is set on the outer wall of the right end of the water pipe 11 .

[0027] The outer walls of the water inlet joint 2 and the water outlet joint 5 are both provided with a plurality of annular protrusions 28 evenly distributed axially; the outer wall of the end of the annular protrusion 28 away from the main body 1 is provided with a docking cone surface 29; the diameter of the docking cone surface 29 gradually decreases in the direction away from the main body 1.

[0028] The main body 1 is made of stainless steel or copper alloy.

[0029] The water pipe 11 is made of stainless steel or copper.

[0030] The method of using the utility model is as follows:

[0031] In order to facilitate the installation and distribution of the pipelines of the water delivery system, the pipelines can be braided tubes. The braided tubes are flexible and can be bent at will, which is more conducive to the layout of the pipelines. When the braided tubes are connected to the water inlet joint 2 and the water outlet joint 5, the clamping method can also be adopted. First, the water inlet joint 2 and the water outlet joint 5 can be respectively inserted into the corresponding ends of the braided tubes, and the outer walls of the water inlet joint 2 and the water outlet joint 5 are provided with a plurality of annular protrusions 28 uniformly distributed in the axial direction. The outer wall of the annular protrusion 28 away from the main body 1 is provided with a docking cone 29, and the diameter of the docking cone 29 is toward the end away from the main body 1. The direction gradually decreases. The existence of the docking conical surface 29 enables the water inlet connector 2 and the water outlet connector 5 to be quickly inserted into the corresponding braided tube ends. When the water inlet connector 2 and the water outlet connector 5 are inserted into the corresponding braided tube ends, the braided tube ends can be pressed from the outside to the inside by a special tool. At this time, the braided tube ends will be deformed under the action of external force, so that they are tightly stuck between adjacent annular protrusions 28, effectively realizing the connection between the water inlet connector 2 and the corresponding braided tube, and the connection between the water outlet connector 5 and the corresponding braided tube, and achieving the effect of quick connection and fixation.

[0032] The left pressing portion 7 is embedded in the left connecting groove 6 of the outer wall of the left connecting seat 3, effectively realizing the fixation between the left connecting seat 3 and the left end of the main body 1, and the left pressing portion 7 is formed by squeezing the left end of the main body 1 by pressure from the outside to the inside, and the right pressing portion 9 is embedded in the right connecting groove 8 of the outer wall of the right connecting seat 4, effectively realizing the fixation between the right connecting seat 4 and the right end of the main body 1, and the right pressing portion 9 is formed by squeezing the main body 1 by pressure from the outside to the inside. This connection and fixing method has great influence on the sizes of the left and right ends of the main body 1, the sizes of the left pressing portion 7, and the sizes of the right pressing portion 9. The size requirement is not high. You only need to insert the left clamping part 7 into the left end port of the main body 1 to complete the connection and fixation between the left end of the main body 1 and the left clamping part 7 by clamping. You only need to insert the right clamping part 9 into the right end port of the main body 1 to complete the connection and fixation between the right end of the main body 1 and the right clamping part 9 by clamping. The existence of the left sealing ring 23 can effectively ensure the sealing of the left end of the main body 1 and the left connecting seat 3 after being clamped and fixed. The existence of the right sealing ring 25 can effectively ensure the sealing of the right end of the main body 1 and the right connecting seat 4 after being clamped and fixed.

[0033] When the water inlet joint 2 and the water outlet joint 5 are respectively connected to the corresponding braided tubes, the water will flow into the water diversion joint 10 through the water inlet joint. At this time, the water flow will be divided into two parts. One part of the water will flow to the left into the water pipe 11 under the impetus of the subsequent water flow, and finally flow out through the water outlet joint 5 and enter the pipeline of the water delivery system to achieve the effect of conveying water flow, while the other part of the water will enter the space formed by the right side wall of the left connecting seat 3, the inner wall of the main body 1, the outer wall of the water diversion joint 10 and the left side wall of the buffer piston 13 through the water diversion hole 12. At this time, the right side wall of the buffer piston 13 and the right connecting seat The air pressure in the space between the left side walls of the left connecting seat 4 and the water pressure in the space enclosed by the right side wall of the left connecting seat 3, the inner wall of the main body 1, the outer wall of the water diversion joint 10 and the left side wall of the buffer piston 13 form a balance. When water hammer occurs, the water pressure rises suddenly. At this time, under the action of the water pressure, the buffer piston 13 will be pushed to the right. As the buffer piston 13 moves to the right, the distance between the right side wall of the buffer piston 13 and the left side wall of the right connecting seat 4 becomes smaller and smaller. The air pressure in the space between the right side wall of the buffer piston 13 and the left side wall of the right connecting seat 4 rises continuously, counteracting the suddenly rising water pressure and achieving the effect of buffering the water pressure.

[0034] When the main body 1 is actually pressed and fixed with the left connecting seat 3 and the right connecting seat 4, the length of the water pipe 11 itself can easily hinder the pressing and fixing process. At this time, the left adjusting washer 16 and the right adjusting washer 17 can use the elasticity of their own materials to automatically adjust the position of the water pipe 11. If there is a certain deviation in the length of the water pipe 11 itself, resulting in the water pipe 11 being slightly longer, as the left and right ends of the main body 1 are successfully pressed and fixed with the left connecting seat 3 and the right connecting seat 4 respectively, under the action of pressure, the left end of the water pipe 11 will squeeze the left adjusting washer 16 to the left, and the right end of the water pipe 11 will squeeze the right adjusting washer 17 to the right. The space vacated by the left adjusting washer 16 and the right adjusting washer 17 can just effectively accommodate the extra length of the water pipe 11, further reducing the difficulty of actual pressing and fixing the main body 1 with the left connecting seat 3 and the right connecting seat 4, and at the same time can effectively ensure the sealing of the left and right ends of the water pipe 11.

[0035] In summary, the utility model has both a water inlet joint 2 and a water outlet joint 5, and the water inlet joint 2 and the water outlet joint 5 can be interconnected through a water pipe 11, so different pipelines can be directly connected through the water inlet joint 2 and the water outlet joint 5, respectively, to connect two independent pipelines in the water delivery system together, thereby reducing the actual space occupied by the pipelines of the water delivery system, facilitating the distribution of the pipelines, and achieving the effect of water delivery at the same time. The water inlet joint 2 can be fixed to the left end of the main body 1 by the left connecting seat 3, and the water outlet joint 5 can be fixed to the right end of the main body 1 by the right connecting seat 4, effectively avoiding the situation in which the difficulty of component processing increases due to threaded connection, effectively improving the yield rate, and reducing production costs.

[0036] The inner walls of the left adjusting washer 16 and the right adjusting washer 17 are coplanar with the inner wall of the water pipe 11, effectively avoiding the existence of the left adjusting washer 16 and the right adjusting washer 17 to hinder the water flow through the water pipe 11, thereby ensuring the smoothness and stability of the water flow.

[0037] An inner sealing ring 19 matching it is provided in the inner sealing groove 18, and an outer sealing ring 21 matching it is provided in the outer sealing groove 20. The existence of the inner sealing ring 19 can effectively ensure the sealing between the inner wall of the buffer piston 13 and the outer wall of the water pipe 11, and the existence of the outer sealing ring 21 can effectively ensure the sealing between the outer peripheral surface of the buffer piston 13 and the inner wall of the main body 1, effectively avoiding air leakage and ensuring the stability of the gas in the space between the buffer piston 13 and the right connecting seat 4 when it is squeezed.

[0038] An annular auxiliary sealing groove 26 is provided on the inner wall of the connecting hole 15, and an auxiliary sealing ring 27 is provided in the auxiliary sealing groove 26 and is set on the outer wall of the right end of the water pipe 11. The existence of the auxiliary sealing ring 27 can effectively ensure the sealing between the outer wall of the right end of the water pipe 11 and the inner wall of the connecting hole 15.

[0039] The main body 1 is made of stainless steel or copper alloy, which ensures the strength of the main body 1 and facilitates extrusion of the end of the main body 1.

[0040] The water pipe 11 is made of stainless steel or copper, which can effectively ensure the strength and service life of the water pipe 11.
