Technical Field

[0001] The invention relates to the technical field of valve bodies, and in particular to a labor-saving two-way valve. Background Art

[0002] The two-way valve is a valve with compact structure and excellent control performance. It uses a ball as the opening and closing part and realizes fluid control by rotating the ball. The large two-way valve is mainly composed of a ball, a valve seat, a valve stem and a transmission device. Its structure is simple but its function is powerful.

[0003] Publication No. CN113357405A is a secondary filtering three-way two-way valve. When operating a manual two-way valve with a larger size, or a manual two-way valve that has not been used for a long time, dust, dirt or rust may accumulate inside, resulting in increased operating resistance, or the sealing performance of the two-way valve is too strong, the sealing gasket is too tight, and the resistance during switching is increased.

[0028] like Figure 1-Figure 5 As shown, a labor-saving two-way valve includes a valve body, including:

[0029] The handle 1 is connected to the valve body switch in a transmission manner. The handle 1 is provided with a first limit notch 11. The handle 1 is also provided with two first moving through grooves 12 that penetrate the handle 1 in a mirror-symmetrical manner.

[0030] A mounting plate 13, fixedly connected to the top of the handle 1, the mounting plate 13 is provided with a second limiting notch 14, the mounting plate 13 is provided with two second movable through grooves 15 that penetrate the mounting plate 13 in a mirror-symmetrical manner, and the two second movable through grooves 15 correspond to the two first movable through grooves 12;

[0031] An auxiliary sliding sleeve 2 is slidably connected to the two first movable through grooves 12 and the two second movable through grooves 15;

[0032] The rebound assembly 3 is transmission-connected between the mounting plate 13 and the auxiliary sliding sleeve 2 .

[0033] In this embodiment, when the two-way valve is difficult to rotate, the auxiliary sleeve 2 is pulled to lengthen the force arm of the handle 1, making it easier to rotate the two-way valve according to the lever principle. After the two-way valve is rotated, the auxiliary sleeve 2 is stored on the handle 1 through the rebound assembly 3, reducing the space occupied by the auxiliary sleeve 2.

[0034] As an optional implementation, Figure 2 , 3 As shown, the auxiliary sliding sleeve 2 includes two movable sliders 21 respectively slidably matched on the two first movable through grooves 12 and the two second movable through grooves 15, and a sleeve 22 is slidably matched on the handle 1, and the upper and lower ends of the two movable sliders 21 are respectively fixedly connected to the upper and lower ends of the inner side of the sleeve 22;

[0035] In this way, the sleeve 22 can slide back and forth on the two first moving through grooves 12 and the two second moving through grooves 15 .

[0036] As an optional implementation, Figure 3 , 4 As shown, a fixing block 23 is fixedly connected to one end of the top of the sleeve 22 away from the valve body, and a handle 24 is rotatably connected to the fixing block 23;

[0037] In this way, when opening and closing the two-way valve, the user can always hold the handle 24, which is convenient for operation.

[0038] As an optional implementation, Figure 3 , 4 As shown, the handle 24 is pear-shaped and narrow at the top and wide at the bottom;

[0039] In this way, the shape of the handle makes it more comfortable for the staff to hold.

[0040] As an optional implementation, Figure 1 , 5As shown, the rebound assembly 3 includes a limiting slide plate 31 slidably connected in the first limiting groove 11, and also includes two connecting members 32 fixed on the top of the mounting plate 13 close to one end of the valve body and the limiting slide plate 31, the connecting member 32 includes a round buckle 33, a rotating member 34 is rotatably connected to the round buckle 33, a tension spring 35 is arranged between the two rotating members 34, the two ends of the tension spring 35 are respectively fixedly connected to the two rotating members 34, a transmission plate 36 is fixedly connected to the round buckle 33 away from the valve body, and the transmission plate 36 is fixedly connected to the sleeve 22;

[0041] In this way, after the sleeve 22 is pulled out, the two rotating members 34 are moved closer to each other under the action of the tension spring 35 , thereby driving the sleeve 22 to retract toward the handle 1 .

[0042] As an optional implementation, Figure 3 , 5 As shown, the bottom end of the handle 1 is fixedly connected to a limiting circular block 37, and the front end of the bottom of the sleeve 22 is rotatably connected to a torsion spring shaft 38, and a fastener 39 is fixedly connected to the torsion spring shaft 38. The fastener 39 includes a hook edge 391 on one side of which is in contact with the limiting circular block 37, and the bending direction of the hook edge 391 is toward the valve body side;

[0043] In this way, the torsion spring shaft 38 normally makes the hook edge 391 point to the limiting circle 37. When the sleeve 22 is pulled out, the back end of the hook edge 391 passes by the limiting circle 37, and the limiting circle 37 contacts the hook edge 391, but the limiting circle 37 does not restrict the hook edge 391 from continuing to move backward. After the hook edge 391 passes the limiting circle 37, the torsion spring shaft 38 returns to its original position. After the force pulling the sleeve 22 to extend is released, when the tension spring 35 pulls the sleeve 22 back to the handle 1, the hook edge 391 will hook the limiting circle 37 to prevent the sleeve 22 from automatically retracting toward the handle 1, thereby facilitating the sleeve 22 to be extended.

[0044] As an optional implementation, Figure 3 As shown, the fastener 39 further includes a shifting edge 392 fixedly connected to the fastener 39, and the shifting edge 392 is provided with an anti-slip texture;

[0045] In this way, when the two-way valve is switched, the dial edge 392 is pushed to rotate the torsion spring shaft 38, and then the hook edge 391 is separated from the limiting round block 37, so that the sleeve 22 is automatically retracted by the spring tension;

[0046] As an optional implementation, Figure 3 As shown, the hook edge 391 is separated from the locking edge 392 of the limiting round block 37 and bent toward the sleeve 22;

[0047] In this way, the hook edge 391 can be released from the locked state of the limiting round block 37 by only pushing the pushing edge 392, so that the sleeve 22 can be reset.

[0048] Those skilled in the art should understand that the discussion of any of the above embodiments is only exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
