Description

Technical Field

[0001] This application relates to the technical field of valves, and in particular to a two-way valve. Background Technology

[0002] A two-way valve consists of one inlet pipe and two outlet pipes. Currently, the two-way valve uses the valve core to adjust the flow direction of the medium within the valve body, and also serves to cut, split, and merge the medium.

[0003] Depending on the valve core, two-way valves can be divided into T-type and L-type two-way valves. A T-type two-way valve can connect three orthogonal pipes or disconnect a third pipe, serving as a diversion or merging valve. An L-type two-way valve can only connect two orthogonal pipes and cannot simultaneously maintain the connection of a third pipe; it can only distribute water flow. However, both T-type and L-type two-way valves only allow simultaneous control of the inlet pipe and two outlet pipes; they cannot adjust each outlet pipe individually. Utility Model Content

[0004] In order to enable independent adjustment of the two water outlet pipes, this application provides a two-way valve.

The inner wall of the mounting ring is connected to the outer wall of the holding column, and the other end of the connecting plate is connected to the outer wall of the holding column. There are several connecting plates, which are spaced apart around the axis of the holding column. The mounting ring is provided with a connecting hole, which passes through the mounting ring along the axis of the mounting ring. The sliding rod is slidably embedded in the connecting hole, and the side wall of the sliding rod is in contact with the wall of the connecting hole. The limiting rod is slidably connected to the mounting ring, and the sliding direction of the limiting rod is perpendicular to the sliding direction of the sliding rod. The side wall of the sliding rod is provided with a first fixing groove, which is used for one end of the limiting rod to be embedded.

[0019] By adopting the above technical solution, the filter screen is connected to the mounting ring, and the inner side of the mounting ring is connected to a connecting plate and a gripping post, which facilitates the user to install and remove the mounting bracket by gripping the post. The sliding rod is embedded in the connecting hole to fix the mounting bracket and the second positioning ring relative to each other along the circumference of the inlet pipe. The limiting rod is embedded in the first fixing groove to fix the mounting bracket and the second positioning ring relative to each other along the axial direction of the inlet pipe, thereby realizing the installation of the filter screen, so as to filter the liquid entering the inlet pipe, reduce the possibility of impurities entering the outlet pipe and causing wear to the opening and closing components, and improve the service life of the two-way valve.

[0020] Preferably, the filtration mechanism further includes a rack, a gear, a second reset member, and a striking block. The gear is rotatably connected to the second positioning ring, and the rotation axis of the gear is perpendicular to the sliding direction of the slide rod.

The rack is slidably connected to the second positioning ring, and the sliding direction of the rack is parallel to the sliding direction of the slide rod. The rack meshes with the gear. One end of the slide rod is connected to the rack. The second reset member is connected between the rack and the second positioning ring, and the second reset member causes the filter screen to tend to move away from the second positioning ring.

[0021] By adopting the above technical solution, when the filter screen is clogged, the pressure on the side of the filter screen away from the second positioning ring increases. The liquid pushes the filter screen to slide towards the second positioning ring, which in turn drives the slide rod to slide, drives the rack to slide, drives the gear to rotate, drives the knocking block to rotate, and the knocking block strikes the filter screen to clean it, ensuring the normal use of the filter screen.

[0022] Preferably, the filtration mechanism further includes a third reset member, a fixing block, a fourth reset member, and a push block.

The push block has a second chamfer at one end away from the filter screen. The second chamfer is located on the side of the push block away from the rack and is used to abut against the fixing block.

[0023] By adopting the above technical solution, the slide bar is slidably connected to the rack. When the filter slides, it compresses the third reset member. When the filter continues to slide and abuts against the push block and the second chamfered fixing block, it pushes the fixing block away from the second fixing groove, thereby releasing the lock of the rack and the second positioning ring. The third reset member returns to the unforced state, pushes the rack to slide, drives the gear to rotate, drives the striking block to rotate, increases the force of the striking block hitting the filter, and improves the cleaning effect of the striking block.

[0024] Preferably, there are a plurality of connecting holes, which are circumferentially spaced around the axis of the mounting ring. The number of sliding rods, limiting rods, racks, gears, second reset components, third reset components, fixing blocks, fourth reset components, and push blocks is the same as the number of connecting holes and corresponds one-to-one. Each gear corresponds to two striking blocks, and the two striking blocks are symmetrically distributed along the rotation axis of the gear.

[0025] By adopting the above technical solution and setting multiple tapping blocks, the filter screen can be cleaned in various areas, ensuring that each area of ​​the filter screen can be used normally.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The number of opening and closing components is the same as the number of water outlet pipes, which makes it easy to control the on and off of the two water outlet pipes separately through two opening and closing components, so that the two water outlet pipes can be adjusted independently.

[0028] 2. When the filter screen is clogged, the pressure on the side of the filter screen away from the second positioning ring increases. The liquid pushes the filter screen to slide towards the second positioning ring, which in turn drives the slide rod to slide, drives the rack to slide, drives the gear to rotate, drives the knocking block to rotate, and the knocking block strikes the filter screen to clean it and ensure the normal use of the filter screen.

[0029] 3. The slide bar is slidably connected to the rack. When the filter slides, it compresses the third reset component. When the filter continues to slide and abuts against the push block and the second chamfered fixing block, it pushes the fixing block away from the second fixing groove, thereby releasing the lock of the rack and the second positioning ring. The third reset component returns to an unforced state, pushes the rack to slide, drives the gear to rotate, drives the striking block to rotate, increases the force of the striking block hitting the filter, and improves the cleaning effect of the striking block.

[0057] The implementation principle of a two-way valve according to an embodiment of this application is as follows: A sealing ring 27 is fitted into a sealing groove 251. A connecting rod 25 is then passed through a connecting hole 123, causing a fifth abutment ring 252 to be embedded in a fourth ring groove 128. A second connecting block 254 is embedded in a second connecting groove 262. A limiting block 261 is embedded in a limiting groove 1221. The rod of a fixing screw 28 passes through a fixing hole 263 and is threadedly connected to the connecting rod 25, thus fixing the handle 26 and the connecting rod 25 relative to each other. Then, a first sealing ring 21 and a ball core 24 are sequentially embedded into the outlet pipe 12. The first sealing ring 21 abuts against a first positioning ring 121, and the first connecting block 253 is embedded in a first connecting groove 241, thus fixing the ball core 24 and the connecting rod 25 relative to each other. The second sealing ring 22 is embedded in the groove 234, and the valve seat 23 is threaded into the outlet pipe 12. The second sealing ring 22 abuts against the outer wall of the ball core 24, and the first abutting ring 232 abuts against the bottom of the third step groove 126.

[0058] Press the unlocking pin 45 with your finger to insert the mounting ring 421 into the water inlet pipe 11. The slide rod 431 abuts against the wall of the connecting hole 4211 and is inserted into the connecting hole 4211. Release the unlocking pin 45 so that the limiting rod 441 is inserted into the first fixing groove 4311, thereby fixing the mounting bracket 42 and the slide rod 431 relative to each other.

[0059] During use, when the filter screen 41 becomes clogged, the pressure on the side of the filter screen 41 away from the second positioning ring 111 increases, pushing the mounting bracket 42 to slide closer to the second positioning ring 111, causing the slide rod 431 to slide. The slide rod 431 presses against the third reset member 436. The mounting ring 421 abuts against the push block 439, which is embedded in the third connecting groove 1114. The second chamfer 4391 abuts against the second guide block 4372, pushing the fixing block 437 to slide. When the fixing block 437 disengages from the second fixing groove 4322, the rack 432 slides, causing the gear 433 to rotate, which in turn causes the striking block 435 to rotate. The striking block 435 strikes the surface of the filter screen 41 near the second positioning ring 111, thus cleaning the filter screen 41. After the pressure on both sides of the filter screen 41 is balanced, the second reset member 434 pushes the rack 432 to slide, which in turn drives the slide rod 431 to slide, causing the mounting bracket 42 to slide away from the second positioning ring 111. The rack 432 abuts against the first chamfer 4371. When the second fixing groove 4322 is aligned with the fixing block 437, the fixing block 437 is embedded in the second fixing groove 4322, thereby fixing the rack 432 and the second positioning ring 111 relative to each other.
