Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a one-way soft-seal gate valve. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate. The direction of movement of the gate is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed, and cannot be used for regulation or throttling. Gate valves achieve sealing through the contact between the valve seat and the gate. Usually, metal materials are welded onto the sealing surface to increase wear resistance. There are rigid gates and resilient gates. Based on the different gates, gate valves are classified as rigid gate valves and resilient gate valves.

[0003] According to a one-way soft-seal gate valve disclosed in patent publication number CN 214305545 U, the device uses a mounting plate to install a buffer device inside the inlet end of the soft-seal gate valve body. When the soft-seal gate valve body is opened to allow fluid to flow, the fluid first rushes into the middle of the overflow plate and is blocked and slowed down by the deceleration cover. The filling material inside the deceleration cover reduces the fluid impact force, and then flows outward from the overflow hole. This reduces the fluid impact force when opening, solving the problem that the gate valve has a large impact force at the moment of opening, which can easily damage the gate valve and reduce its service life after long-term use. However, this device is not convenient for disassembling the filter screen, making it inconvenient for manual cleaning of the filter screen. After long-term use, the filter screen is prone to clogging, which affects the subsequent use of the device.

[0004] To address this issue, we propose a one-way soft-seal gate valve. Utility Model Content

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1

[0026] like Figure 1-6 As shown, this utility model provides a technical solution: a one-way soft-seal gate valve, including a valve body 1, an inlet pipe 2 connected to the lower part of the valve body 1, and a connecting assembly 3 between the valve body 1 and the inlet pipe 2. The connecting assembly 3 includes a disassembly and assembly mechanism 31 disposed inside the inlet pipe 2. A protective mechanism 32 is disposed outside the valve body 1. An outlet pipe is connected to the lower part of the valve body 1. The disassembly and assembly mechanism 31 includes an installation groove 311 opened inside the inlet pipe 2. An installation frame 312 is inserted into the installation groove 311. A filter screen 313 is fixedly connected to the inner wall of the installation frame 312. A sealing element is fixedly connected to the inner wall of the inlet pipe 2. The bottom outer wall of the inlet pipe 2 is provided with a groove 315. A sliding rod 316 is fixedly connected to the inner wall of the groove 315. A slider 317 is slidably connected to the outer wall of the sliding rod 316. A first spring 318 is fixedly connected to the inner wall of the groove 315. A limit rod 319 is fixedly connected to the outer side of the slider 317. The inner wall of the mounting groove 311 is provided with an inner groove 3110. A hollow column 3111 is fixedly connected to the inner wall of the inner groove 3110. A solid column 3112 is sleeved inside the hollow column 3111. A second spring 3113 is fixedly connected to the inner wall of the hollow column 3111. A top plate 3114 is fixedly connected to the outer end of the solid column 3112.

[0027] In this embodiment, the inner side of the limiting rod 319 is fitted to the outer side of the mounting frame 312, and one end of the first spring 318 is fixedly connected to the slider 317. Through the cooperation of the mounting groove 311, mounting frame 312, filter screen 313, sealing ring 314, sliding groove 315, sliding rod 316, slider 317, first spring 318, limiting rod 319, inner groove 3110, hollow column 3111, solid column 3112, second spring 3113, and ejector plate 3114, it is convenient for manual disassembly and cleaning of the filter screen 313, which can prevent the filter holes of the filter screen 313 from being blocked and affecting the subsequent use of the valve body 1.

[0028] Furthermore, there are two sealing rings 314, symmetrically distributed on both sides of the mounting frame 312, and the sealing rings 314 are located in the gap between the mounting groove 311 and the mounting frame 312.

[0029] Furthermore, one end of the second spring 3113 is fixedly connected to the solid column 3112.

[0030] When the filter screen 313 needs to be disassembled and cleaned, simply push the limiting rod 319 manually. Under the action of the sliding rod 316 and the slider 317, the limiting rod 319, which is fixedly connected to the outside of the slider 317, can move away from the outside of the mounting frame 312. Then, under the action of the second spring 3113, the solid column 3112 can drive the ejector plate 3114 to press the mounting frame 312 outward, thereby popping the mounting frame 312 outward. Then the filter screen 313 can be taken out, which facilitates manual cleaning of the filter screen 313 and prevents the filter holes of the filter screen 313 from becoming clogged, thus affecting the normal use of the device.
