Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a soft-sealed gate valve which is convenient for replacing the gate valve. Background Art

[0002] Soft-sealed gate valve, industrial valve, the opening and closing parts of the soft-sealed gate valve are the gate disc, the movement direction of the gate disc is perpendicular to the direction of the fluid, the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

[0003] When the gate of a soft-sealed gate valve is damaged during use and needs to be replaced, it is extremely troublesome. This requires disassembly of the top and then replacement of the gate. Generally, the valve cover is fixed with bolts, and when replacement is required, the bolts need to be rotated. However, long-term use of the bolts will cause thread slippage, which is not conducive to disassembly and replacement. Utility Model Content

[0026] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0027] Reference Figure 1-3 , Figure 1 It is a schematic diagram of the structure of the valve body of some embodiments of the utility model; Figure 2 It is a structural schematic diagram of the top of the connecting pipe of some embodiments of the utility model; Figure 3 It is a schematic structural diagram of the valve cover of some embodiments of the utility model.

[0028] The utility model provides a soft-sealed gate valve which is convenient for replacing the gate valve, comprising a gate valve body 1, wherein the gate valve body 1 comprises a connecting pipe 2, a valve cover 3 is arranged on the top of the connecting pipe 2, sliding grooves 21 are arranged on both sides of the top of the connecting pipe 2, and blocks 31 matching the sliding grooves 21 are arranged on the two sides opposite to the sliding grooves 21 at the bottom of the valve cover 3.

[0029] The connecting pipe 2 on the valve body 1 is provided with a detachable valve cover 3, which is connected with the block 31 through the sliding slot 21, and then the valve cover 3 is rotated to make the block 31 stuck in the sliding slot 21 to complete the connection. When it needs to be replaced, the valve cover 3 can be taken out by rotating it in the opposite direction to replace the gate. In this way, it is easy to disassemble without bolts, and it will not be difficult to disassemble due to thread slippage. Generally, the top of the gate is controlled up and down by a threaded rod, so the valve cover 3 can be disconnected from one end of the top of the threaded rod, or it can be threadedly connected, or it can be rotated to remove the valve cover 3 for replacement.

[0030] According to some embodiments of the utility model, the connecting pipe 2 is optionally provided with connecting grooves 22 on the other two sides, the valve cover 3 is provided with through grooves 32 at positions opposite to the connecting grooves 22, and the through grooves 32 are connected to the connecting grooves 22 through the connecting block 4. The connecting block 4 is inserted from the through groove 32 and slid into the connecting groove 22, but the length of the connecting block 4 will not exceed the total length of the connecting groove 22 and the through groove 32, and this can prevent the valve cover 3 from accidentally rotating to cause water leakage, and can perform a limiting role. At the same time, if the length does not exceed, it can also prevent others from taking it away easily.

[0031] According to some embodiments of the utility model, optionally, an annular groove 23 is provided at the top of the connecting pipe 2, and a sealing ring 24 is provided in each of the annular grooves 23. The annular groove 23 is arranged at the innermost part of the top of the connecting pipe 2, and then a sealing ring 24 is added thereto to increase the sealing between the connecting pipe 2 and the valve cover 3 to avoid water leakage.

[0032] According to some embodiments of the utility model, optionally, a rotating rod 33 is provided on both sides of the valve cover 3. In this way, the valve cover 3 can be rotated better to replace the gate later.

[0033] According to some embodiments of the utility model, optionally, the surface of the rotating rod 33 is provided with an anti-skid cover 34. The anti-skid property of the rotating rod 33 is increased, so that the rotating rod 33 can be rotated well without slipping.

[0034] According to some embodiments of the utility model, optionally, a threaded hole 41 is provided on the top of the connection block 4. Because the length will not exceed the total length of the connection groove 22 and the through groove 32, the connection block 4 will not protrude, but it needs to be taken out to rotate the valve cover 3, so a threaded hole 41 is provided to take it out with the help of a matching threaded rod connection.

[0035] It should be understood that the embodiments disclosed in the present invention are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features understood by ordinary technicians in the relevant field. It should also be understood that the terms used herein are only used for the purpose of describing specific embodiments and are not meant to be limiting.

[0036] The "embodiment" mentioned in the specification means that the specific features or characteristics described in conjunction with the embodiment are included in at least one embodiment of the present utility model. Therefore, phrases or "embodiment" appearing in various places throughout the specification do not necessarily refer to the same embodiment.

[0037] In addition, the described features or characteristics may be combined in one or more embodiments in any other suitable manner. In the above description, some specific details, such as thickness, quantity, etc., are provided to provide a comprehensive understanding of the embodiments of the utility model. However, those skilled in the relevant art will understand that the utility model can be implemented without one or more of the above specific details or can also be implemented using other methods, components, materials, etc.
