AI Technical Summary
The existing gate valve structure results in a large volume and increases the number of steps and difficulty in processing the valve seat.
The valve core mounting hole is set at a preset angle with the fluid channel. The rod part of the sealing component is threaded to the valve core, and the sealing part abuts against the end of the mounting hole for sealing. Combined with the annular sealing ring and counterclockwise thread structure, production costs are reduced.
This reduces the size of the shut-off valve, simplifies the processing steps and complexity, and improves the sealing effect and dustproof performance.

[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.
[0032] As Figures 1 to 12 shown, an embodiment of the present application provides a shut-off valve, which includes a valve seat 10, a valve core 20 and a plugging member 30. The valve seat 10 is provided with a fluid passage 11 and a mounting hole 12, and the fluid passage 11 and the mounting hole 12 are communicatively arranged. The extension direction of the mounting hole 12 is arranged at a preset angle with the extension direction of the fluid passage 11. The valve core 20 is installed in the mounting hole 12, and the valve core 20 is provided with a connecting hole 21. The connecting hole 21 is provided with a first internal thread. The plugging member 30 includes a rod body part 31 and a covering part 32. The rod body part 31 is provided with a first external thread matched with the first internal thread. The rod body part 31 is threadedly connected with the connecting hole 21. The covering part 32 is arranged at the end of the rod body part 31. The covering part 32 is arranged protruding from the end of the mounting hole 12, so that the covering part 32 abuts against the end of the mounting hole 12.
[0033] After the valve core 20 is installed in the mounting hole 12, the rod body part 31 of the plugging part 30 is inserted into the valve core 20 and is threadedly connected with the valve core 20, and the covering part 32 is abutted against the end of the mounting hole 12 to cover and seal and prevent dust from the end of the mounting hole 12 through the covering part 32. The above structure is simple to manufacture, does not need to occupy extra space, and does not greatly increase the occupied volume of the stop valve.
[0034] In the embodiment, the end of the mounting hole 12 has a first sealing plane, the covering part 32 is a cover plate, the cover plate has a second sealing plane, and the first sealing plane and the second sealing plane are oppositely arranged. Specifically, the first sealing plane and the second sealing plane can be attached to seal the mounting hole 12 and improve the sealing effect.
[0035] Specifically, the stop valve in the embodiment further includes a sealing part 40 arranged between the end of the mounting hole 12 and the covering part 32. With such a structure, the sealing effect can be improved.
[0036] In the embodiment, the sealing part 40 is an annular sealing ring sleeved on the rod body part 31. With such a structure, the compactness of the structure can be effectively improved, and the sealing effect can be better improved. In addition, the end face can also be sealed and dustproof under a smaller torque.
[0037] In the embodiment, the plugging part 30 is made of a plastic material. With such a structure, the production and manufacturing cost can be effectively reduced.
[0038] Specifically, the covering part 32 in the embodiment is a circular cover plate or a polygonal cover plate. Specifically, the polygonal cover plate can be a triangular cover plate, a rectangular cover plate, a pentagonal cover plate, or a hexagonal cover plate, etc. With the polygonal cover plate, external force can be easily applied to the cover plate to facilitate the operation of the covering part 32.
[0039] In the embodiment, the first internal thread and the first external thread can both be counterclockwise thread structures. With such a structure, the first internal thread and the first external thread are both reverse thread structures, so that counterclockwise rotation causes the snap ring to be limited (as shown in Figure 6 the valve core 20 cannot be removed, and the rod body part 31 is tightened, and the thread fastening force causes the end face of the rod body part 31 to be firmly attached to the end of the mounting hole, thereby playing a dustproof role. Alternatively, the first internal thread and the first external thread can both be clockwise thread structures.
[0040] Specifically, the connecting hole 21 in the embodiment includes a first hole section 211 and a second hole section 212 connected with each other, the first internal thread is located at the first hole section 211, the second hole section 212 is located at a side of the first hole section 211 away from the cover part 32, and the second hole section 212 has a hexagonal hole structure in cross section. With such a structure, the valve core 20 can be conveniently installed by setting the second hole section 212 as a polygonal hole structure. Specifically, the polygonal hole can be used to close or open the valve port of the stop valve. The second hole section 212 is arranged at the side of the first hole section 211 away from the cover part 32, so that the installation of the plugging part 30 can be facilitated. Preferably, the polygonal hole structure can be a hexagonal hole structure or a quadrangular hole structure.
[0041] In the embodiment, the included angle between the extension direction of the fluid passage 11 and the extension direction of the mounting hole 12 is less than or equal to 90°.
[0042] Specifically, the valve core 20 is provided with a second external thread in the embodiment, the mounting hole 12 is provided with a second internal thread matched with the second external thread, and the valve core 20 is threadedly connected with the valve seat 10. With such a structure, the installation of the valve core 20 can be facilitated.
[0043] The stop valve in the embodiment further includes a connecting pipe 50 connected with the valve seat 10.
[0044] As can be seen from the above description, the above-mentioned embodiments of the present application achieve the following technical effects: the occupied volume of the stop valve is reduced, and the machining steps and machining difficulty of the valve seat are reduced.
