DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] A large flushing volume adjustable drain valve, such as Figure 1-Figure 7 As shown, it includes a valve seat 1 and a valve body 2. The valve seat 1 is sealed and connected to the bottom opening of a water tank (not shown). The valve body 2 is supported on the valve seat 1. The valve seat 1 is opened and closed by the valve body 2. When opened, water in the water tank flows out from the opening. When closed, the water tank stores water. Among them, the valve body 2 includes a cylinder body 21, and the cylinder body 21 includes a partition 212 with a through hole. The partition 212 separates the water tank 22 from the float chamber 23. A full pull rod 24 is arranged in the through hole to guide movement. A float 25 is arranged at the lower end of the full pull rod 24. A bottom valve 26 is arranged at the lower end of the float 25. The bottom valve 26 opens or closes the opening of the valve seat 1; a bypass hole 211 connected to the float chamber is arranged on the side wall of the cylinder body 21, and the bypass hole 211 is an axially extending waist-shaped hole. A baffle 27 is slidably arranged on the side wall of the cylinder body 21, and an adjustment hole 271 is arranged on the baffle 27. The adjustment hole 271 is connected to the bypass hole 211, and the discharge volume is adjusted by adjusting the height of the adjustment hole 271.
[0024] In one embodiment, if Figure 1-Figure 7 As shown, two guide bars 213 are protruding from the side wall of the cylinder body 21, and the guide bars 213 are arranged on both sides of the bypass hole. The baffle plate 27 is in a long strip shape, and first guide grooves 275 cooperating with the guide bars 213 are arranged on both sides of the baffle plate 27. The guide bars 213 are slidably connected with the first guide grooves 275. The baffle plate 27 is guided to move up and down through the first guide grooves 275 and the guide bars 213, thereby realizing the adjustment of the height position of the adjustment hole 271.
[0025] In one embodiment, if Figure 1-Figure 7 As shown, a second guide groove is formed between the guide bar 213 and the cylinder body 21, and the side wall 272 of the first guide groove is located in the second guide groove, and the two guide each other, so that the baffle 27 can move stably.
[0026] In one embodiment, if Figure 1-Figure 7 As shown, the first guide groove 275 is tightly matched with the guide bar 213, so that the movement between the baffle plate 27 and the cylinder body 21 has damping to prevent the baffle plate 27 from sliding down; at the same time, the baffle plate 27 is closely attached to the surface of the bypass hole 211 to play a sealing role.
[0027] In one embodiment, if Figure 1-Figure 7 As shown, a stopper 214 is provided at the upper end of the guide bar 213, and the stopper 214 is used to limit the upper limit position of the upward movement of the baffle 27 to prevent the baffle 27 from moving beyond the stroke.
[0028] In one embodiment, if Figure 1-Figure 7 As shown, a shift block 272 is convexly provided on the baffle plate 27, which is convenient for the user to hold to control the baffle plate 27 to move up and down.
[0029] In one embodiment, if Figure 1-Figure 7As shown, the lower end of the guide bar 213 is extended to be provided with a positioning tooth groove 215, and the lower end of the baffle 27 is extended to be provided with a positioning block 273. When the baffle 27 is fixed, the positioning block 273 is clamped in the positioning tooth groove 215. It can effectively ensure the current position of the adjustment hole 271. Among them, the baffle 27 is usually plastic, and there is toughness between the positioning block 273 and the baffle 27, that is, the positioning block 273 has the ability to move toward the positioning tooth groove 215.
[0030] In one embodiment, if Figure 1-Figure 7 As shown, a limit block 216 is protruding from the cylinder body 21, and a limit portion 274 is provided on the baffle 27. The limit block 216 cooperates with the limit portion to limit the lower limit position of the baffle 27 moving downward.
[0031] When the utility model is used, Figure 1-Figure 7 As shown, the full pull rod 24 is pulled, the bottom valve 26 is pulled away from the closed position, and the water in the tank flows out from the opening of the valve seat 1. When the water in the water tank is lower than the bypass hole 211, the full pull rod 24 will fall, and the bottom valve 26 will close the valve seat 1. When the water discharge volume needs to be adjusted, the baffle 27 is moved by the shift block 272, and the positioning block 273 is pushed outward and falls into another positioning tooth groove 215. The utility model realizes small-amplitude adjustment, and the guide bar 213 and the first guide groove 275 are tightly matched, so that the baffle 27 has damping when moving, which facilitates the baffle 27 to move in a small amplitude.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should be included in the scope of protection of the claims of the present invention.
