Description

Technical Field

[0001] This invention relates to the field of three-way seat valve technology, specifically to an electric three-way seat valve that is easy to connect. Background Technology

[0002] A three-way valve is a valve device with three ports, one inlet and two outlets. When using a three-way seat valve, the flow of the medium can be controlled by rotating the opening and closing parts.

[0003] Existing three-way seat valves can generally only control the flow of the medium and the flow rate by manually rotating the valve core. They are difficult to control electrically, and the flow regulation operation is not precise enough. In addition, the three-way valve is equipped with one inlet pipe and two outlet pipes, and the medium can enter from one end and exit from the other. It is difficult to switch to one inlet and one outlet, which makes it inflexible in use. Summary of the Invention

[0004] The purpose of this invention is to provide an electric three-way seat valve that is easy to connect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric three-way seat valve for easy docking, comprising a valve body, a sleeve penetrating the top of the valve body, a rotating shaft rotatably connected inside the sleeve, the rotating shaft penetrating the sleeve and connected to a block, a valve core movably connected inside the valve body, the block slidably connected to the top of the valve core, a through hole being provided on the valve core, a baffle being fixed to the bottom of the valve core, water outlet pipes being symmetrically fixed on both sides of the valve body, a water inlet pipe being fixed to the bottom of the valve body, docking pipes being fixed on the inner walls of the outer ends of the two water outlet pipes and the inner wall of the bottom of the water inlet pipe, an annular groove being provided on the outer side of the docking pipe, and a rubber ring being fixed inside the annular groove.

[0006] Preferably, brackets are symmetrically fixed on both sides of the top of the valve body, and a support box is fixed on the top of the two brackets. A worm gear is rotatably connected to the front side of the support box, and the worm gear passes through the front side of the support box and is connected to the knob.

[0007] Preferably, a motor is fixed on the rear inner wall of the valve body, and the output end of the motor is connected to the worm gear.

[0008] Preferably, a worm gear is meshed with one side of the worm, a support plate is fixed on one inner wall of the support box, the worm gear is rotatably connected to the bottom of the support plate, and the rotating shaft is fixed to the bottom of the worm gear.

[0009] Preferably, an electric telescopic column is fixed to the bottom of the support box, and the electric telescopic column passes through the bottom of the support box and is connected to the sleeve, the sleeve passing through the bottom of the support box.

[0010] Preferably, a collar is fixed to the top of the valve core, and the collar is rotatably connected to the outside of the sleeve.

[0011] Preferably, the top of the valve core is provided with a sliding groove, and the block is slidably connected in the sliding groove.

[0012] Preferably, air grooves are symmetrically provided on both sides of the two outlet pipes and both sides of the inlet pipe, and a piston is slidably connected in the air groove. The piston is connected to one inner wall of the air groove by a spring, and a movable block is fixed on the outside of the piston.

[0013] Preferably, the bottom of the water inlet pipe and the outer end faces of the two water outlet pipes are provided with a storage groove, and the movable block passes through the storage groove.

[0014] Preferably, an annular groove is formed in the side wall of the docking pipe, and the annular groove is connected to two air slots through two connecting pipes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This easy-to-connect electric three-way seat valve can achieve a firm connection. When connecting the external pipe to the inlet pipe or connecting the external pipe to the two outlet pipes, the moving block and piston are squeezed and moved. The rubber ring automatically expands and presses against the inner wall of the external pipe, achieving a locking effect. Then, the mounting ring can be fixed to the external pipe using external fasteners.

[0016] 2. This easy-to-connect electric three-way seat valve can achieve manual or electric control of the medium flow direction and flow rate. If one of the outlet pipes needs to be used, the knob can be manually rotated to drive the worm gear to rotate, or the worm gear, worm wheel, rotating shaft, square block and valve core can be rotated electrically to easily adjust the position of the through hole so that the through hole is aligned with the corresponding outlet pipe. The opening size of the through hole can be controlled by adjusting the rotation angle of the valve core, thereby controlling the flow rate.

[0017] 3. This easy-to-connect electric three-way seat valve can achieve flexible switching between one inlet and two outlets, or one inlet and one outlet, as well as control of unilateral flow. If two outlet pipes need to be used simultaneously, the sleeve, collar, and valve core move upwards, and the bottom of the valve core rises between the two outlet pipes, with both outlet pipes in the open state. The flow can be controlled by adjusting the rising height of the valve core. Subsequently, the position of the baffle can be adjusted by rotating the valve core to easily control the flow of the corresponding outlet pipe. This device can achieve flexible switching between one inlet and two outlets, or one inlet and one outlet. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8The present invention provides a technical solution: an electric three-way seat valve that is easy to connect, including a valve body 1, a sleeve 10 passing through the top of the valve body 1, a rotating shaft 9 rotatably connected inside the sleeve 10, the rotating shaft 9 passing through the sleeve 10 and connected to a block 13, a valve core 11 movably connected inside the valve body 1, the block 13 slidably connected to the top of the valve core 11, a through hole 15 opened on the valve core 11, a baffle 16 fixed at the bottom of the valve core 11, water outlet pipes 18 symmetrically fixed on both sides of the valve body 1, a water inlet pipe 19 fixed at the bottom of the valve body 1, and connecting pipes 27 fixed on the inner walls of the outer ends of the two water outlet pipes 18 and the inner wall of the bottom of the water inlet pipe 19, an annular groove 28 opened on the outer side of the connecting pipe 27, and a rubber ring 29 fixed in the annular groove 28.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, brackets 2 are symmetrically fixed on both sides of the top of the valve body 1, and support boxes 3 are fixed on the top of the two brackets 2. A worm gear 5 is rotatably connected to the front side of the support box 3, and the worm gear 5 passes through the front side of the support box 3 and is connected to the knob 4. When the knob 4 is manually rotated, the worm gear 5 can be rotated, thereby driving the corresponding component to rotate.

[0024] In this embodiment, as Figure 2 and Figure 3 As shown, a motor 6 is fixed on the rear inner wall of the valve body 1, and the output end of the motor 6 is connected to the worm gear 5. The worm gear 5 can rotate under the action of the motor 6, thereby driving the corresponding component to rotate.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, a worm wheel 7 is meshed with one side of the worm 5, and a support plate 8 is fixed on one inner wall of the support box 3. The worm wheel 7 is rotatably connected to the bottom of the support plate 8, and the rotating shaft 9 is fixed to the bottom of the worm wheel 7. The rotation of the worm 5 can drive the worm wheel 7 to rotate, thereby driving the rotating shaft 9 to rotate.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, an electric telescopic column 17 is fixed at the bottom of the support box 3, and the electric telescopic column 17 passes through the bottom of the support box 3 and is connected to the sleeve 10. The sleeve 10 passes through the bottom of the support box 3 and can move up and down under the telescopic action of the electric telescopic column 17, thereby driving the corresponding components to move up and down.

[0027] In this embodiment, as Figure 2 and Figure 7 As shown, a collar 12 is fixed to the top of the valve core 11, and the collar 12 is rotatably connected to the outside of the sleeve 10. When the sleeve 10 moves up and down, it can drive the collar 12 and the valve core 11 to move up and down as a whole.

[0028] In this embodiment, as Figure 7 and Figure 8 As shown, a groove 14 is provided on the top of the valve core 11, and the block 13 is slidably connected in the groove 14. When the sleeve 10 moves up and down, it drives the collar 12 and the valve core 11 to move up and down, and the block 13 slides in the groove 14. When the rotating shaft 9 rotates, it can drive the block 13 to rotate, thereby driving the valve core 11 to rotate, which facilitates the positioning of the through hole 15 and the baffle 16.

[0029] In this embodiment, as Figure 5 and Figure 6 As shown, air grooves 21 are symmetrically provided on both sides of the two outlet pipes 18 and both sides of the inlet pipe 19. A piston 23 is slidably connected in the air groove 21. The piston 23 is connected to one inner wall of the air groove 21 by a spring 22. A movable block 24 is fixed on the outside of the piston 23. When the two outlet pipes 18 and the inlet pipe 19 are connected to the external pipe by the connecting pipe 27, the movable block 24 is squeezed and moves, thereby driving the piston 23 to move, which facilitates the expulsion of air in the air groove 21. The spring 22 supports the piston 23 and helps the piston 23 to reset.

[0030] In this embodiment, as Figure 5 and Figure 6 As shown, a receiving groove 25 is provided at the bottom of the water inlet pipe 19 and on the outer end face of the two water outlet pipes 18. The movable block 24 passes through the receiving groove 25. When the movable block 24 is squeezed and moves, the piston 23 moves accordingly, and the movable block 24 eventually retracts into the receiving groove 25.

[0031] In this embodiment, as Figure 5 and Figure 6 As shown, an annular groove 28 is provided in the side wall of the docking pipe 27, and the annular groove 28 is connected to two air grooves 21 through two connecting pipes 26. The two connecting pipes 26 serve to connect the annular groove 28 and the two air grooves 21. When the movable block 24 and the piston 23 are squeezed and moved, the rubber ring 29 can automatically expand under the action of air pressure and press against the inner wall of the external pipe, so as to achieve a firm docking. Then, fasteners can be used to fix the two water outlet pipes 18 and the water inlet pipe 19 together with the external pipe.

[0032] The method of use and advantages of this invention: The working process of this easy-to-connect electric three-way seat valve is as follows: like Figures 1 to 8As shown: First, connect the two outlet pipes 18 and the inlet pipe 19 to the external pipe. The external pipe is placed on the outside of the connecting pipe 27. The movable block 24 is moved by the pressure of the external pipe, which drives the piston 23 to move. The rubber ring 29 automatically expands under the action of air pressure and presses against the inner wall of the external pipe, which can achieve a firm connection. Then, use external fasteners to fix the mounting ring 20 to the external pipe.

[0033] If the medium needs to flow in one direction, open one of the outlet pipes 18, manually rotate the knob 4 to drive the worm gear 5 to rotate, or use the motor 6 to electrically rotate the worm gear 5. The rotation of the worm gear 5 drives the worm wheel 7 to rotate, and the rotating shaft 9 rotates accordingly, thereby driving the block 13 and the valve core 11 to rotate, thus connecting the through hole 15 with the corresponding outlet pipe 18. By controlling the rotation angle of the valve core 11, the opening size of the through hole 15 can be controlled, thereby realizing the flow control. If the medium needs to flow to both outlet pipes 18 simultaneously, the electric telescopic column 17 extends, the sleeve 10 moves upward, thereby driving the collar 12 and valve core 11 to move upward. The bottom of the valve core 11 rises between the two outlet pipes 18, and both outlet pipes 18 are in the open state. The medium can flow to both outlet pipes 18 simultaneously. The position of the baffle 16 can be adjusted by rotating the valve core 11. After the baffle 16 is rotated to the beginning of either outlet pipe 18, the opening size of the baffle 16 can be controlled by controlling the rotation angle of the valve core 11, thereby controlling the flow rate of the corresponding outlet pipe 18.
