[0002] In industrial production, plug valves are a common type of valve used to control the flow of materials in pipelines. However, existing plug valves have some shortcomings. On the one hand, during the material flow process, the material may contain impurities, which can easily enter the plug valve. This can not only affect the normal operation of the plug valve, but also cause wear on the internal components of the plug valve, reducing its service life. On the other hand, existing plug valves do not perform well in terms of sealing, and are prone to material leakage. This can not only waste materials, but also pollute the production environment and even cause safety accidents.

[0003] To address this issue, a high-sealing plug is proposed. Utility Model Content

The filter frame has two sliders on its side wall. The filter screen is fixed inside the filter frame. The top of the filter frame has a limiting plate with a handle on its upper surface. The filter media is inserted into the filter box.

[0008] The feed inlet has a fastening groove on its side wall and a thread on its inner wall. The flange that contacts the feed inlet has a retaining ring on its side wall and a thread on its outer wall. When the filter is fixed at the feed inlet, the retaining ring is threaded into the fastening groove.

[0009] A sealing groove is provided on the side wall of the feed inlet, and a sealing ring is provided in the sealing groove. The diameter of the sealing groove is smaller than the diameter of the fastening groove.

[0010] The filter box and the feed inlet are equipped with sealing gaskets, which are annular in shape.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, a high-sealing stopcock includes a valve body 1, a valve core 7, and a valve cover 2. The valve body 1 has an inlet 12 and an outlet 11 on both sides. The valve body 1 is the basic support structure of the entire stopcock, providing installation positions for other components and forming a channel for material flow. The inlet 12 and outlet 11 on both sides are connected to external pipes to realize the input and output of materials. The indicator 13 on the front and back can intuitively indicate the flow direction of materials, which is convenient for operators to judge and operate.

[0022] The valve core 7 is located at the center inside the valve body 1. Rotating the valve core 7 controls the flow of material. The valve core 7 typically adopts a shape that matches the internal channel of the valve body 1. When the valve core 7 rotates to a specific position, the inlet 12 and outlet 11 are fully connected, allowing material to pass smoothly. When the valve core 7 rotates to another position, the inlet 12 and outlet 11 are disconnected, and the material stops flowing. The flow rate of the material can also be adjusted by precisely controlling the rotation angle of the valve core 7. The valve cover 2 is located on the top of the valve body 1 and is fixedly connected to the valve body 1 by bolts. The top of the valve cover 2 has a top cover 21, which is fixedly connected to the valve cover 2 by bolts. The valve cover 2 seals the interior of the valve body 1. The front and back of the valve body 1 are symmetrically equipped with indicator marks 13 to indicate the flow direction of the material. Operators can quickly and accurately determine the flow direction of the material by observing the indicator marks 13, improving the convenience and accuracy of operation.

[0023] The upper end of the valve core 7 is provided with a connecting handle 71, which is integrated with the valve core 7. The connecting handle 71 passes through the valve cover 2 and the top cover 21. The top of the connecting handle 71 is provided with a handle 6, which is engaged with the end of the connecting handle 71. The operator can rotate the handle 6 to drive the valve core 7 to rotate, thereby controlling the flow and flow of materials. A filter device is provided at the feed inlet 12, which is used to filter the materials at the feed inlet 12.

[0024] The filtration device includes a filter box with flanges 31 symmetrically arranged on both sides. The filter box contains two filter media, each comprising a filter frame 52 and a filter screen 54. Two sliders 53 are provided on the side wall of the filter frame 52, allowing the filter media to be inserted into the filter box via the sliders 53 for easy installation and replacement. The filter screen 54 is fixed within the filter frame 52. A limiting plate 5 is provided at the top of the filter frame 52, and a handle 51 is provided on the upper surface of the limiting plate 5. The filter media is inserted into the filter box, allowing operators to easily remove and insert the filter media via the handle 51.

[0025] The feed inlet 12 has a fastening groove 14 on its side wall and a thread on its inner wall. The flange 31, which is in contact with the feed inlet 12, has a retaining ring 32 on its side wall and a thread on its outer wall. When the filter device is fixed at the feed inlet 12, the retaining ring 32 is threaded to the fastening groove 14. This connection method is simple and reliable and can ensure a tight connection between the filter device and the feed inlet 12.

[0026] A sealing groove 15 is provided on the side wall of the feed inlet 12, and a sealing ring 16 is provided in the sealing groove 15. The diameter of the sealing groove 15 is smaller than the diameter of the fastening groove 14. When the filter device is connected to the feed inlet 12, the sealing ring 16 can play a sealing role to prevent material from leaking from the connection.

[0027] A sealing gasket 4 is provided at the filter box and the feed inlet 12. The sealing gasket 4 is annular, which further enhances the sealing between the filter device and the feed inlet 12.
