Description

Technical Field

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

[0002] Angle valve is an angle stop valve, which uses a spherical opening and closing part consistent with the ball valve. The spherical opening and closing part is rotated by the valve stem to open and close the angle valve, thereby controlling the water flow rate.

[0024] A seat plate 33 is provided below the left valve body 1 and the right valve body 2 ; through holes 34 matching the water inlet connector 3 are provided on the left and right sides of the seat plate 33 ; a locking portion 35 fitting with the upper surface of the seat plate 33 is provided on the outer wall of the water inlet connector 3 .

[0025] The method of using the utility model is as follows:

[0026] Since the left linkage arm 15 and the right linkage arm 16 are respectively arranged on the linkage seat 14 at the lower end of the handle 13, when the handle 13 is rotated, the left linkage arm 15 and the right linkage arm 16 rotate synchronously, and the left linkage arm 15 is stuck between the left limit plates 11 on the front and rear sides, and the right linkage arm 16 is stuck between the right limit plates 12 on the front and rear sides. When the left linkage arm 15 rotates, the left linkage block 9 will drive the ball-type opening and closing member 5 in the left valve body 1 to rotate synchronously through the valve stem 7 to realize the opening and closing of the left valve body 1. When the right linkage arm 16 rotates, the right linkage block 10 will drive the ball-type opening and closing member 5 in the right valve body 2 to rotate synchronously through the valve stem 7 to realize the right The opening and closing of the valve body 2, when the left valve body 1 is opened, the water inlet connector 3 of the left valve body 1 is connected with the water outlet connector 8 of the left valve body 1, so as to realize the water flow transmission of the pipeline connected with the left valve body 1; when the right valve body 2 is opened, the water inlet connector 3 of the right valve body 2 is connected with the water outlet connector 8 of the right valve body 2, so as to realize the water flow transmission of the pipeline connected with the right valve body 2. It can be seen that, by simply turning the handle 13, the opening and closing of the left valve body 1 and the right valve body 2 can be controlled at the same time, effectively ensuring the consistency of the opening and closing states of the left valve body 1 and the right valve body 2, thereby ensuring the consistency of the water delivery states of the pipelines respectively connected with the left valve body 1 and the right valve body 2, and ensuring the water delivery quality to the greatest extent.

[0027] A left guide slope 20 is provided on the left side wall of the lower part of the left limit head 18, and the lower end of the left guide slope 20 is inclined to the right. A right guide slope 21 is provided on the right side wall of the lower part of the right limit head 19, and the lower end of the right guide slope 21 is inclined to the left. The left guide slope 20 can slide downward along the upper edge of the right end surface of the left linkage block 9 when the left linkage arm 15 is inserted into the gap between the left limit plates 11 on the front and rear sides, which is beneficial for the lower end of the left linkage arm 15 to quickly pass downward through the gap between the left limit plates 11 on the front and rear sides to complete the card connection between itself and the left linkage block 9. The right guide slope 21 can slide downward along the upper edge of the left end surface of the right linkage block 10 when the right linkage arm 16 is inserted into the gap between the right limit plates 12 on the front and rear sides, which is beneficial for the lower end of the right linkage arm 16 to quickly pass downward through the gap between the right limit plates 12 on the front and rear sides to complete the card connection between itself and the right linkage block 10.

[0028] The front and rear side walls of one end of the valve stem 7 passing through the valve stem hole 6 are provided with symmetrical limiting planes 22, and the left side wall of the left linkage block 9 and the right side wall of the right linkage block 10 are both provided with a limiting hole 23 matching the end of the valve stem 7 passing through the valve stem hole 6, the end face of the valve stem 7 fits with the bottom of the limiting hole 23, and the limiting planes 22 on the front and rear sides of the end of the valve stem 7 fit with the inner walls on the front and rear sides of the limiting hole 23. This structural restriction can not only ensure that the left linkage block 9 and the right linkage block 10 can achieve synchronous rotation with the valve stem 7, but also facilitate the disassembly and assembly between the left linkage block 9, the right linkage block 10 and the valve stem 7.

[0029] A left pressing arm 24 is provided at the center of the lower end surface of the left linkage arm 15, and a right pressing arm 25 symmetrical to the left pressing arm 24 is provided at the center of the lower end surface of the right linkage arm 16. The existence of the left pressing arm 24 facilitates the application of force to the left linkage arm 15, and the existence of the right pressing arm 25 facilitates the application of force to the right linkage arm 16. When the left pressing arm 24 and the right pressing arm 25 approach each other, the left linkage arm 15 and the right linkage arm 16 are deformed, and the elastic spacing between the left linkage arm 15 and the right linkage arm 16 becomes smaller. At this time, the left limit head 18 at the lower end of the left linkage arm 15 can be detached from the lower surface of the left linkage block 9, and the right limit head 19 at the lower end of the right linkage arm 16 can be detached from the lower surface of the right linkage block 10, thereby realizing the separation of the handle 13 from the left linkage block 9 and the right linkage block 10.

[0030] A left card slot 26 is provided on the right side wall of the left pressing arm 24, and a right card slot 27 corresponding to the position of the left card slot 26 is provided on the left side wall of the right pressing arm 25. A fastener 28 is provided between the left pressing arm 24 and the right pressing arm 25. A support rod 29 is provided at the center of the right end face of the fastener 28. The right end face of the support rod 29 is pressed against the bottom of the right card slot 27. A threaded hole 30 is provided at the center of the left end face of the fastener 28. A screw rod 31 matching with it is threaded in the threaded hole 30. The left end of the screw rod 31 penetrates into the left card slot 26 to the left and presses against the bottom of the left card slot 26. A pressure portion 32 is provided on the outer wall of the screw rod 31 between the left pressing arm 24 and the fastener 28. The distance between the right end face of the screw rod 31 and the bottom of the threaded hole 30 is greater than the distance between the pressure portion 32 and the fastener 28, and the distance between the pressure portion 32 and the fastener 28 is greater than the distance between the groove of the left card slot 26. The existence of the screw rod 31 and the support rod 29 can form a support between the left pressing arm 24 and the right pressing arm 25, so that the left pressing arm 24 and the right pressing arm 25 are always kept in a tensioned state, thereby effectively avoiding the loosening of the left linkage arm 15 and the right linkage arm 16, and effectively ensuring the stability of the handle 13 when connecting the left linkage block 9 and the right linkage block 10 through the left linkage arm 15 and the right linkage arm 16. When it is necessary to remove the screw rod 31 and the support rod 29, it is only necessary to hold the fastener 28 and then turn the pressure applying portion 32 to realize the rotation of the screw rod 31, so that the screw rod 31 penetrates into the threaded hole 30 to the right. At this time, the left end of the screw rod 31 will move out of the left slot 26. Without the support of the screw rod 31 and the support rod 29, the left pressing arm 24 and the right pressing arm 25 can be easily pressed, and the left linkage arm 15 and the right linkage arm 16 can be quickly disassembled.

[0031] A seat plate 33 is provided under the left valve body 1 and the right valve body 2, and through holes 34 matching the water inlet joint 3 are provided on the left and right sides of the seat plate 33. The outer wall of the water inlet joint 3 is provided with a locking portion 35 that fits with the upper surface of the seat plate 33. The existence of the seat plate 33 can effectively ensure the stability of the water inlet joint 3 of the left valve body 1 and the water inlet joint 3 of the right valve body 2, thereby ensuring the stability of the handle 13 when opening and closing the left valve body 1 and the right valve body 2.
