Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a corrosion-resistant stop valve structure. Background Art

[0002] The stop valve, also known as the gate valve, is one of the most widely used valves. The reason why it is so popular is that the friction between the sealing surfaces during opening and closing is small, it is relatively durable, the opening height is not large, it is easy to manufacture and maintain, and it is suitable not only for medium and low pressures, but also for high pressures.

[0003] The stem of the stop valve can transmit external operating force, such as the manually rotating handwheel or the driving force of the actuator, to the valve disc to realize the opening and closing of the valve. In daily use, since part of the stem is usually exposed to the outside, external dew or water that penetrates the valve body can easily adhere to the exposed stem. At this time, it is necessary to manually clean the moisture on the stem. If the stem is not cleaned in time for a long time, the stem may rust, which will affect the use of the stem. Therefore, it is necessary to redesign a corrosion-resistant stop valve structure to address the above problems. Utility Model Content

[0004] The utility model aims to solve the problems in the background technology and proposes a corrosion-resistant stop valve structure.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A corrosion-resistant stop valve structure comprises a flange 1, a valve stem 10 is rotatably connected to the flange 1, a sponge 11 is sleeved on the outer wall of the valve stem 10, a runner 7 is fixedly connected to one end of the valve stem 10, a driving device is arranged on the outer wall of the runner 7, a mounting seat 2 is fixedly mounted on the upper end surface of the flange 1, the valve stem 10 passes through the mounting seat 2, and the bottom end of the sponge 11 is fixedly connected to the upper end surface of the mounting seat 2, a cleaning device is arranged on the upper end surface of the mounting seat 2, and the output end of the cleaning device is connected to the outer wall of the valve stem 10, and the sponge 11 is connected to the output end of the cleaning device, and a plurality of fixing blocks 5 are fixedly connected to the output end of the cleaning device.

[0022] The driving device includes a fixed plate 6, and the fixed plate 6 is fixedly installed on the outer wall of the rotating wheel 7. A push rod 12 is fixedly installed on the lower end surface of the fixed plate 6. A connecting ball 13 is rotatably installed on the end of the push rod 12 away from the fixed plate 6. It should be noted that: by rotating the rotating wheel 7, the fixed plate 6 can be rotated synchronously, and then the rotation of the fixed plate 6 can drive the push rod 12 to move, and the push rod 12 can push the fixed block 5 through the connecting ball 13.

[0023] The cleaning device is wrapped with a spring 3, and the spring 3 is fixedly mounted on the upper end surface of the mounting seat 2. One end of the spring 3 away from the mounting seat 2 is fixedly connected to a mounting plate 4, and the mounting plate 4 is slidably sleeved on the outer wall of the valve stem 10, and the upper end surface of the sponge 11 is fixedly connected to the lower end surface of the mounting plate 4, and a plurality of fixed blocks 5 are fixedly mounted on the upper end surface of the mounting plate 4. When the fixed block 5 is pushed by the push rod 12, the fixed block 5 can drive the mounting plate 4 to slide on the outer wall of the valve stem 10. The spring 3 and the sponge 11 can be compressed by the movement of the mounting plate 4, so that the moisture in the sponge 11 can be compressed out of the sponge 11, thereby keeping the sponge 11 dry.

[0024] The upper end surface of the mounting seat 2 is provided with a plurality of drainage grooves 9, and the bottom wall of each drainage groove 9 is inclined. It should be noted that such a design can ensure that the fluid in the sponge 11 can be better passed through the drainage groove 9 to the outside.

[0025] Both sides of each fixing block 5 are inclined. It should be noted that such a design can ensure that the connecting ball 13 can pass through the inclined surface of the fixing block 5 .

[0026] A plurality of anti-skid grooves 8 are provided on the outer wall of the rotating wheel 7 . It should be noted that the plurality of anti-skid grooves 8 can increase the friction between the palm of the operator and the rotating wheel 7 , which can facilitate the operator to twist the rotating wheel 7 .

[0027] When the utility model rotates the rotating wheel 7, the rotating wheel 7 can drive the valve stem 10 to rotate, and the valve stem 10 can be used to control the flow of the stop valve. At the same time, the rotation of the rotating wheel 7 can drive the fixed plate 6 to rotate synchronously, and the fixed plate 6 can drive the push rod 12 to rotate. The push rod 12 can drive the connecting ball 13 to slide on the fixed block 5. When the connecting ball 13 rolls to the end face of the fixed block 5 through the inclined surface of the fixed block 5, the fixed block 5 will be pushed. At this time, the fixed block 5 will compress the sponge 11 and the spring 3 through the mounting plate 4.

[0028] When the push rod 12 drives the connecting ball 13 to rotate between two adjacent fixed blocks 5, the spring 3 will be reset, and the reset of the spring 3 can drive the mounting plate 4 to move synchronously. At this time, the spring 3 can drive the mounting plate 4 to slide on the outer wall of the valve stem 10. At this time, the screen will be reset synchronously with the movement of the mounting plate 4. If there is moisture on the outer wall of the valve stem 10 at this time, the sponge 11 can absorb the moisture on the valve stem 10 to prevent the valve stem 10 from rusting.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
