Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a grooved gate valve with anti-leakage function. Background Technology

[0002] Grooved gate valves are industrial valves that use a grooved (clamp) connection, featuring quick installation, high safety and reliability, and no restrictions on installation site. Their structural design can solve displacement problems caused by misalignment and temperature differences in pipeline connections, and supports vibration and noise isolation performance. Based on the actuation method, they can be divided into rising stem gate valves and non-rising stem gate valves. Rising stem gate valves visually indicate their open / closed status through the exposed thread on the valve stem. These valves are widely used in fire protection, water supply and drainage, petrochemical, and coal mining fields. Materials are mostly corrosion-resistant materials such as ductile iron and stainless steel, and some products feature full-bore design and zero-flow-resistance characteristics.

[0003] Currently available grooved gate valves often only use a simple gate to cut off the flow of liquid. However, there may be gaps between the gate and the inside of the valve, which can lead to liquid leakage. This results in poor liquid blocking effect and poor practicality.

[0004] Therefore, a grooved gate valve with anti-leakage function is needed to solve the leakage problem. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a grooved gate valve with anti-leakage function. It achieves double anti-seepage through a hollow gate plate and two sealing plugs, completely solving the leakage problem and improving the practicality of the grooved gate valve.

[0006] To achieve the above objectives, the present invention proposes the following specific solutions:

[0007] A grooved gate valve with anti-leakage function includes a valve body. A flow-stopping groove is provided on the inner side of the valve body. Flow guide holes are symmetrically provided on the inner wall of the flow-stopping groove. Flow guide pipes are symmetrically fixed to the side walls of the valve body, communicating with the inner sides of the flow guide holes. A storage box is fixed to the center of the top surface of the valve body, communicating with the inner side of the flow-stopping groove. A sealing frame is fixed to the center of the top surface of the storage box, communicating with the inner side of the storage box. A rectangular hollow column is movably inserted into the inner side of the storage box. A column penetrates the sealing frame. A hollow gate plate is fixed at the lower end of the rectangular hollow column. The hollow gate plate is located inside the flow-stopping groove. The rectangular hollow column and the inner side of the hollow gate plate are connected. The inner wall of the hollow gate plate is symmetrically provided with moving holes. A partition is fixed in the middle of the bottom surface of the inner side of the hollow gate plate. Vertical plates are symmetrically provided on the inner side of the rectangular hollow column. A sealing plug is fixed at the lower end of the vertical plate. The sealing plug is located on both sides of the partition plate. The sealing plug penetrates the moving hole. One end of the sealing plug is movably inserted into the inner side of the guide hole.

[0008] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, a fixing plate is fixed on the outer wall of one side of the upper end of the rectangular hollow column, and the top surface of the fixing plate is provided with a threaded hole.

[0009] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, a screw is threadedly connected to the inner side of the threaded hole, and the screw passes through the threaded hole.

[0010] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, the lower end of the screw is fixed with a rotating shaft, and the lower end of the rotating shaft is fixed with a rotating disk.

[0011] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, a fixing block is fixed on the outer wall of one side of the upper end of the storage box, a rotating hole is provided on the top surface of the fixing block, the rotating shaft passes through the rotating hole, a rotating groove is provided through the lower end of the rotating hole, and the rotating disk is movably sleeved on the inner side of the rotating groove.

[0012] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, a connecting groove is provided in the middle of one side wall of the sealing block, a spring is fixed on the inner wall of one side of the connecting groove, and one end of the spring is fixed on the side wall of the partition.

[0013] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, a T-shaped plate is movably inserted into the inner side of the upper end of the rectangular hollow column, and the vertical plate is located on both sides of the T-shaped plate.

[0014] As a preferred technical solution of the grooved gate valve with anti-leakage function of this utility model, both the sealing frame and the sealing plug are made of elastic material.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model uses a hollow gate plate embedded in the inner side of the stop groove in the valve body. The elastic force of the spring pushes the sealing plug at the lower end of the vertical plate through the moving hole and inserts it into the inner side of the guide hole. The deformation of the elastic sealing plug tightly fits the inner wall of the guide hole. Under the double blocking of the hollow gate plate and the sealing plug, the leakage problem is completely solved and the flow interception capacity of the gate valve is improved.

[0017] The T-shaped plate of this invention is inserted into the inside of the rectangular hollow column, positioned between two vertical plates, preventing the two vertical plates from moving. This ensures that the sealing plug will not detach from the inside of the guide hole. By pulling out the T-shaped plate and moving the two vertical plates closer together, the two sealing plugs can be moved out of the inside of the guide hole. Then, by rotating the screw, the screw drives the fixing plate to move upward, which in turn moves the rectangular hollow column upward. The rectangular hollow column then moves the hollow gate plate upward, detaching it from the inside of the stop groove and storing it in the storage box, allowing the liquid to flow normally. The operation is simple and convenient. Attached Figure Description

The T-shaped plate 4 is inserted into the inner side of the rectangular hollow column 2 and is located between the two vertical plates 3, which can prevent the vertical plate 3 from moving and ensure that the sealing plug 31 is not easily moved out of the guide hole 121, thus improving stability.

[0032] The working principle and usage process of this utility model:

[0033] In use, the two guide pipes 13 are connected to the liquid conveying pipeline respectively. The hollow gate plate 23 is located inside the stop groove 12. The sealing plug 31 is pushed by the elastic force of the spring 312, passes through the moving hole 231 and is inserted into the inside of the guide hole 121. The two sealing plugs 31 seal the two guide holes 121 respectively, thereby blocking the flow of liquid. The T-shaped plate 4 is inserted into the inside of the rectangular hollow column 2 and is located between the two vertical plates 3, so that the two vertical plates 3 cannot move and prevent the sealing plug 31 from falling out of the inside of the guide hole 121.

[0034] When the gate valve needs to be opened, first pull out the T-shaped plate 4, grasp the two vertical plates 3 with one hand, bring the two vertical plates 3 close to each other, and drive the two sealing plugs 31 close to each other, compressing the spring 312. After the two sealing plugs 31 are separated from the inside of the two guide holes 121 respectively, turn the screw 22 with the other hand. The screw 22 rotates inside the threaded hole 211 on the fixed plate 21, driving the fixed plate 21 to move upward. The fixed plate 21 drives the rectangular hollow column 2 to move upward. The rectangular hollow column 2 drives the hollow gate plate 23 to move upward and separate from the inside of the stop groove 12, and move it into the inside of the storage box 11 for storage, so that the liquid can flow normally.
