Description

Technical Field

[0001] The utility model relates to a water hammer valve, in particular to a single-handle linkage water hammer valve. Background Art

[0002] A water hammer valve refers to a valve equipped with a water hammer eliminator. The water hammer valve is used on the pipeline in the water supply system. During the water supply process in the pipeline, if the water flow rate suddenly changes due to some external reasons, water hammer will occur. This phenomenon is called water hammer. The water hammer eliminator can effectively eliminate the shock wave caused by the water hammer phenomenon. The existence of the water hammer valve can effectively ensure the stability of the water supply system during water supply.

[0003] Due to the complexity of the water delivery system, more water hammer valves are often installed in the water delivery system to control different pipelines in the water delivery system. During the delivery process, two pipelines are often required to deliver water at the same time, and a water hammer valve can only control a single pipeline. If two pipelines need to deliver water at the same time, it is necessary to hold the handles of the two water hammer valves at the same time and open the two water hammer valves at the same time. Although this opening method can eventually enable both pipelines to deliver water, there will inevitably be differences in turning the handles on different water hammer valves, and the movements cannot be completely consistent. The ball-type opening and closing parts in the water hammer valves rotate synchronously with the handles. Once the handles of the two water hammer valves rotate inconsistently, the rotation angles of the ball-type opening and closing parts in the two water hammer valves will also be different, which will eventually affect the water delivery flow of the two water hammer valves and cannot guarantee the water delivery quality. Summary of the invention

[0004] The utility model aims to solve the existing technical problem and provide a single-handle linkage water hammer valve, which can control two water hammer valves at the same time through one handle to achieve synchronous opening and closing of the two water hammer valves, thereby effectively ensuring the consistency of water delivery states of two different pipelines and effectively ensuring the water delivery quality.

[0028] The method of using the utility model is as follows:

[0029] Since the left threaded head 12 has a left cutout 14 in the middle that matches the valve stem 5 on the left valve body 1, and the right threaded head 13 has a right cutout 15 in the middle that matches the valve stem 5 on the right valve body 2, when completing the connection between the valve stem 5 on the left valve body 1 and the valve stem 5 on the right valve body 2, the left threaded head 12 and the right threaded head 13 can be vertically moved from top to bottom through the linkage seat 11, so that the valve stem 5 on the left valve body 1 can be smoothly inserted into the left cutout 14, and the valve stem 5 on the right valve body 2 can be smoothly inserted into the right cutout 15. This connection method can quickly complete the connection between the valve stem 5 on the left valve body 1 and the valve stem 5 on the right valve body 2 after the positions of the left valve body 1 and the right valve body 2 are fixed. At the same time, the existence of the left limiting nut 16 can effectively prevent the right end of the valve stem 5 on the left valve body 1 from being inserted from the left cutout 14. 4 is disengaged, and the existence of the right limiting nut 17 can effectively prevent the left end of the valve stem 5 on the right valve body 2 from being disengaged from the right cutout 15, thereby ensuring the stability of the valve stem 5 on the left valve body 1 and the valve stem 5 on the right valve body 2 when they are connected, and the left thread head 12 used for connecting the valve stem 5 on the left valve body 1 and the right thread head 13 used for connecting the valve stem 5 on the right valve body 2 are both arranged on the linkage seat 11. When the handle 18 drives the linkage seat 11 to rotate, under the action of the clamping plane 10, the valve stem 5 on the left valve body 1 and the valve stem 5 on the right valve body 2 both rotate, thereby realizing the simultaneous rotation of the spherical opening and closing members 4 in the left valve body 1 and the right valve body 2, thereby realizing the effect of one handle 18 controlling the opening and closing of the two water hammer valves at the same time, effectively ensuring the consistency of the water delivery state of the two different pipelines, and effectively ensuring the water delivery quality.

[0030] A lower screw hole 19 is provided at the center of the upper surface of the linkage seat 11, a lower screw portion 20 screwed into the lower screw hole 19 is provided at the center of the lower end surface of the handle 18, a spherical handle head 21 is provided at the upper end of the handle 18, an upper screw hole 22 is provided at the center of the lower surface of the handle head 21, and an upper screw portion 23 screwed into the upper screw hole 22 is provided at the center of the upper end surface of the handle 18. This fixing method facilitates the disassembly and assembly of the handle 18 and the handle head 21. When the handle 18 and the handle head 21 are damaged, they can be quickly replaced. The diameter of the handle head 21 is larger than the diameter of the handle. This structural design facilitates the user to better grasp the handle through the handle head 21 and apply force to the linkage seat 11 through the handle 18.

[0031] The outer walls of the left limit nut 16 and the right limit nut 17 are both provided with a number of evenly distributed anti-slip protrusions 24. The presence of the anti-slip protrusions 24 can effectively increase the friction between the user's hand and the outer walls of the left limit nut 16 and the right limit nut 17, making it easier for the user to rotate the left limit nut 16 and the right limit nut 17.

[0032] The inner diameters of the left limiting nut 16 and the right limiting nut 17 are both larger than the diameter of the valve stem 5. The front and rear sides of the end of the valve stem 5 that passes through the valve stem hole 6 are provided with mutually symmetrical limiting steps 25. The left end face of the left thread head 12 fits with the limiting step 25 on the valve stem 5 that passes through the valve stem hole 6 on the left valve body 1, and the right end face of the right thread head 13 fits with the limiting step 25 on the valve stem 5 that passes through the valve stem hole 6 on the right valve body 2. The distance between the left limiting nut 16 and the left valve body 1 is greater than the thickness of the left limiting nut 16, and the distance between the right limiting nut 17 and the right valve body 2 is greater than the thickness of the right limiting nut 17. When the positions of the left valve body 1 and the right valve body 2 are fixed, the distance between the right end face of the valve stem 5 on the left valve body 1 and the left end face of the valve stem 5 on the right valve body 2 cannot be changed, and the above fixing method can make the left limiting nut 16 smoothly disengage from the left thread head 12, and make the right limiting nut 17 smoothly fall off the right thread head 13 when the valve stem 5 on the left valve body 1 and the valve stem 5 on the right valve body 2 are both fixed, thereby realizing the rapid separation of the left thread head 12 and the right end of the valve stem 5 on the left valve body 1, and realizing the rapid separation of the right thread head 13 and the left end of the valve stem 5 on the right valve body 2.

[0033] A seat plate 26 is provided below the left valve body 1 and the right valve body 2, a left connecting hole 27 matching the water inlet connector 7 at the lower end of the left valve body 1 is provided on the left side of the seat plate 26, a right connecting hole 28 matching the water inlet connector 7 at the lower end of the right valve body 2 is provided on the right side of the seat plate 26, a locking portion 29 fitting with the upper surface of the seat plate 26 is provided on the water inlet connector 7, the existence of the seat plate 26 can connect the water inlet connectors 7 on the left and right sides, thereby effectively ensuring the stability of the left valve body 1 and the right valve body 2.

[0034] The seat plate 26 is composed of a left connecting plate 2601 and a right connecting plate 2602. The left connecting plate 2601 is located on the left side of the right connecting plate 2602. The left connecting hole 27 is provided on the left connecting plate 2601, and the right connecting hole 28 is provided on the right connecting plate 2602. The left connecting plate 2601 has symmetrical left fixing parts 30 on the upper and lower sides of the right end, and the right connecting plate 2602 has symmetrical right fixing parts 31 on the upper and lower sides of the left end. The left side wall of the right fixing part 31 is in contact with the right side wall of the left fixing part 30. The left fixing part 30 is provided with a plurality of evenly distributed left through holes 32, and the right fixing part 30 is provided with a plurality of evenly distributed left through holes 32. The fixing portion 31 is provided with a plurality of right through holes 33 corresponding to the positions of the left through holes 32. A fixing screw 34 passes through the left through hole 32 and the right through hole 33 to the right in sequence and is screwed with a nut 35 that fits with the right side wall of the right fixing portion 31. The right side wall of the head of the fixing screw 34 fits with the left side wall of the left fixing portion 30. As the seat plate 26 is divided into a left connecting plate 2601 and a right connecting plate 2602, the seat plate 26 no longer restricts the positions of the left valve body 1 and the right valve body 2. The water inlet joints 7 on the left and right sides can be connected after all the assembly of the left valve body 1 and the right valve body 2 is completed.

[0035] The spherical opening and closing component 4 is provided with an opening and closing hole 36 which runs through the front and back thereof. The center of the upper surface of the spherical opening and closing component 4 is provided with an auxiliary hole 37 which is connected with the opening and closing hole 36. The auxiliary hole 37 and the opening and closing hole 36 are perpendicular to each other. The front end opening of the opening and closing hole 36 is connected with the water outlet joint 8, and the auxiliary hole 37 is connected with the water hammer arrester 9. When the spherical opening and closing component 4 is rotated forward ninety degrees driven by the valve stem 5, the water hammer arrester 9 is connected with the water inlet joint 7 through the opening and closing hole 36, and the opening and closing hole 36 is connected with the water outlet joint 8 through the auxiliary hole 37, thereby finally realizing the opening of the left valve body 1 and the right valve body 2.
