[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Depend on Figure 1-6 The present invention relates to a bidirectional flow switchable shut-off valve, comprising a valve box 1, an inlet pipe 2 installed on one side of the valve box 1, a first outlet pipe 3 installed on the back of the valve box 1, a second outlet pipe 4 installed on the other side of the valve box 1, a water flow control component 5 installed inside the valve box 1, and a snap-fit ​​fixing component 6 installed on the top of the valve box 1.

A stop valve 502 is movably installed inside the valve chamber 501, and a flow valve 503 is installed at the top of the stop valve 502. The outer walls of both the stop valve 502 and the flow valve 503 are in close contact with the inner wall of the valve chamber 501. The flow valve 503 is at the same height as the inlet pipe 2. A flow element is installed inside the flow valve 503, including a central groove 504 located inside the flow valve 503. Three flow slots 505 are provided on the outer side of the central groove 504, with adjacent flow slots 505 set at a 90-degree angle. The height of the stop valve 502 is the same as the height of the flow valve 503. The internal height of the valve chamber 501 is equal to the height of the stop valve 502. The flow valve 503, which is three times the height of the pipe, has three flow channels 505. When two flow channels 505 are connected to the inlet pipe 2 and the first outlet pipe 3 respectively, water is introduced into the first outlet pipe 3. When the three flow channels 505 are connected to the inlet pipe 2, the first outlet pipe 3 and the second outlet pipe 4 respectively, water is introduced into the first outlet pipe 3 and the second outlet pipe 4. When two flow channels 505 are connected to the inlet pipe 2 and the second outlet pipe 4 respectively, water is introduced into the second outlet pipe 4. This facilitates switching the direction of water flow. When the stop valve 502 moves upward, the stop valve 502 closes the inlet pipe 2, the first outlet pipe 3 and the second outlet pipe 4, thereby facilitating the cutoff of water flow and the control of water flow.

[0028] The snap-fit ​​fixing assembly 6 includes a top cylinder 601 fixedly installed at the top of the valve box 1. Four lower snap-fit ​​grooves 602 and four upper snap-fit ​​grooves 603 are equally spaced on the inner wall of the top cylinder 601. The upper snap-fit ​​grooves 603 are located above the lower snap-fit ​​grooves 602. The distance between the lower snap-fit ​​grooves 602 and the upper snap-fit ​​grooves 603 is the same as the height of the stop valve 502. A longitudinal rod 604 is coaxially mounted on the top of the stop valve 502. The longitudinal rod 604 is located inside the top cylinder 601, and the longitudinal rod 604... The outer wall is tightly attached to the inner wall of the top cylinder 601. A top block 605 is fixedly installed at the top of the longitudinal rod 604. The top block 605 is located above the top cylinder 601. A movable groove 606 is opened inside the longitudinal rod 604. The top of the movable groove 606 extends into the interior of the top block 605. A guide rod 609 is horizontally installed inside the movable groove 606. Two movable plates 610 are symmetrically and movably installed inside the movable groove 606. The movable plates 610 are slidably connected to the guide rods 609. The bottom ends of the movable groove 606 are aligned with the inner wall of the top cylinder 601. The device has a lower rod groove 607. Two movable plates 610 are each equipped with a locking rod 612 on their opposite sides. The locking rod 612 is located inside the lower rod groove 607, and its end engages with the lower locking groove 602. Springs 611 are symmetrically installed between the two movable plates 610. Upper rod grooves 608 are symmetrically opened on both sides of the top of the movable groove 606, extending to the outer side of the top block 605. Push rods 613 are installed on the opposite sides of the two movable plates 610, passing through the upper rod grooves 606. On the outer side of the top block 605, a push block 614 is fixedly installed at the end of the push rod 613. Four lower slots 602 and four upper slots 603 are opened at equal angles on the inner wall of the top cylinder 601. When the flow valve 503 and the water inlet pipe 2 are at the same height, the locking rod 612 engages with the lower slots 602 to facilitate water flow. When the stop valve 502 and the water inlet pipe 2 are at the same height, the locking rod 612 engages with the upper slots 603 to facilitate water flow cutoff and valve body adjustment.

[0029] Working principle: In operation, initially, the two flow channels 505 are connected to the inlet pipe 2 and the first outlet pipe 3 respectively, and the other flow channel 505 is located near the front of the valve box 1. After water enters the inlet pipe 2, it flows out from the first outlet pipe 3. When the flow valve 503 is rotated 90 degrees clockwise, the three flow channels 505 are connected to the inlet pipe 2, the first outlet pipe 3, and the second outlet pipe 4 respectively. After water enters the inlet pipe 2, it flows out from the first outlet pipe 3 and the second outlet pipe 4. When the flow valve 503 is rotated 90 degrees counterclockwise, the two flow channels 505 are connected to the inlet pipe 2 and the second outlet pipe 4 respectively. The other flow channel 505 is located near the front of the valve box 1, so that after water enters the inlet pipe 2, it flows out from the second outlet pipe 4, thus facilitating the switching of the water flow direction.

[0030] When water flow needs to be stopped, pull the stop valve 502 upward, so that the flow valve 503 moves to the same height as the inlet pipe 2, the first outlet pipe 3, and the second outlet pipe 4, so that the stop valve 502 closes the inlet pipe 2, the first outlet pipe 3, and the second outlet pipe 4, thus completing the water flow stop.

[0031] When water flows, the lever 612 engages with the lower slot 602, so that the flow valve 503 and the inlet pipe 2 are at the same height, which facilitates water flow. When the water flow is blocked, the stop valve 502 moves upward so that the lever 612 engages with the upper slot 603.

[0032] During adjustment, press the two push blocks 614 close to each other, thereby pushing the two movable plates 610 close to each other, so that the locking rod 612 enters the movable groove 606. After adjustment, the movable plate 610 moves outward under the elastic force of the spring 611, so that the locking rod 612 is locked into the lower locking groove 602 or the upper locking groove 603, which locks and fixes the stop valve 502 and the flow valve 503 for easy adjustment.
