Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting gate valves, in particular to a fire-fighting gate valve which is convenient for inspection and disassembly. Background Art

[0002] Fire gate valves are key components used in fire protection systems. They can control the on / off flow of water to ensure that water can be quickly provided in an emergency. Fire gate valves are usually installed in fire protection pipe networks to connect to fire hoses or other fire protection equipment.

[0003] Since fire gate valves are a key part of fire protection facilities, regular maintenance of fire gate valves is an important part of daily work. Regular maintenance of fire gate valves helps to understand their usage and avoid the fire gate valves being unable to open and use in the event of a fire.

[0004] However, most of the existing fire gate valves are integrated structures. Although this structure can effectively increase the overall strength, the integrated structure has blind spots for maintenance, leaving hidden dangers for safety. In addition, the detachable structure of the existing fire gate valve body is installed and fixed with multiple bolts, which is particularly inconvenient during disassembly.

[0005] Therefore, the utility model proposes a fire gate valve which is easy to inspect and disassemble. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a fire gate valve that is easy to repair and disassemble.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a fire gate valve that is easy to inspect and disassemble, comprising an adjusting mechanism, an upper gate valve seat and a lower gate valve seat, wherein the upper gate valve seat is arranged on the top of the lower gate valve seat, the adjusting mechanism passes through the upper gate valve seat and is arranged between the upper gate valve seat and the lower gate valve seat, a clamping assembly is provided at the connection between the upper gate valve seat and the lower gate valve seat, and connecting assemblies are provided on both sides of the lower gate valve seat;

[0008] The connecting assembly includes a rotating seat, which is connected to the lower gate valve seat. A rotating limiting groove is provided on the rotating seat, and a flange connecting cylinder is rotatably connected to the rotating limiting groove.

[0009] As a preferred embodiment, a rotating sleeve is provided on one side of the flange connection tube close to the rotation limiting groove, and the flange connection tube is rotatably connected in the rotation limiting groove through the rotating sleeve.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the flange connecting cylinder is rotatably connected in the rotating limit groove through the rotating sleeve, so that when the lower gate valve seat is docked with other connecting pipes, there is no need to adjust other objects to align the docking holes of the two connecting flanges, and the flange connecting cylinder can be directly rotated. This method is convenient and fast and is suitable for use in environments with narrow operating space such as fire cabinets.

[0011] As a preferred embodiment, a sealing rubber sleeve is embedded in the flange connection tube, the other end of the sealing rubber sleeve is located inside the rotation limiting groove, and the length of the sealing rubber sleeve is greater than the length of the flange connection tube.

[0012] The beneficial effect of adopting the above further scheme is: by sealing the connection between the sealing rubber sleeve, the flange connecting tube and the rotation limit groove, water seepage and leakage due to the rotational connection between the rotation limit groove and the flange connecting tube during use can be prevented.

[0013] As a preferred embodiment, the clamping assembly includes a clamping seat, and there are two clamping seats in total, and the two clamping seats are respectively arranged on both sides of the connection between the upper gate valve seat and the lower gate valve seat.

[0014] The beneficial effect of adopting the above-mentioned further scheme is: replacing the traditional bolt installation with the clamping assembly is not only convenient and quick, but also saves disassembly time. By clamping the two clamping seats at the connection between the upper gate valve seat and the lower gate valve seat, the upper gate valve seat and the lower gate valve seat are limited to prevent the upper gate valve seat and the lower gate valve seat from separating up and down during use.

[0015] As a preferred embodiment, both sides of the two engaging seats are provided with engaging limit plates, and two adjacent engaging limit plates are slidably connected to limit covers.

[0016] The beneficial effect of adopting the above-mentioned further scheme is: by mutually engaging and limiting the limit plate and the limit cover, the engaging seat cannot be displaced to both sides under the action of the limit cover, and cooperates with the upper gate valve seat and the lower gate valve seat to pull to both sides, further limiting the limit cover, and preventing the limit cover from being easily removed from the engaging limit plate.

[0017] As a preferred embodiment, a limiting pin penetrating the limiting plate is inserted into the limiting cover.

[0018] The beneficial effect of adopting the above further solution is: the limit cover is limited by the limit pin inserted on the limit cover. Since the limit pin passes through the clamping limit plate, the limit cover and the clamping limit plate can be prevented from separating during use, thereby improving the stability of the device.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] 1. In the utility model, the flange connection cylinder is rotatably connected in the rotation limit groove by a rotating sleeve, so that when the lower gate valve seat is docked with other connecting pipes, there is no need to adjust other objects to align the docking holes of the two connecting flanges. The flange connection cylinder can be directly rotated. This method is convenient and fast, and is suitable for use in environments with narrow operating space such as fire cabinets, thereby improving the work efficiency during disassembly and maintenance.

[0021] 2. In the present invention, the traditional bolt installation is replaced by a clamping assembly, which is not only convenient and fast, but also saves disassembly time. By clamping the two clamping seats at the connection between the upper gate valve seat and the lower gate valve seat, the upper gate valve seat and the lower gate valve seat are limited to prevent the upper gate valve seat and the lower gate valve seat from separating up and down during use. The limit cover is limited by a limit pin inserted on the limit cover. Since the limit pin passes through the clamping limit plate, the limit cover and the clamping limit plate can be prevented from separating during use, thereby improving the convenience during disassembly and maintenance.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-4 As shown, the utility model provides a technical solution: a fire gate valve that is easy to repair and disassemble, including an adjusting mechanism 1, an upper gate valve seat 11 and a lower gate valve seat 12, the upper gate valve seat 11 is arranged on the top of the lower gate valve seat 12, the adjusting mechanism 1 passes through the upper gate valve seat 11 and is arranged between the upper gate valve seat 11 and the lower gate valve seat 12, a clamping component 2 is provided at the connection between the upper gate valve seat 11 and the lower gate valve seat 12, and a connecting component 3 is provided on both sides of the lower gate valve seat 12; the connecting component 3 includes a rotating seat 31, the rotating seat 31 is connected to the lower gate valve seat 12, and a rotating limit groove 32 is provided on the rotating seat 31. A flange connection tube 33 is rotatably connected to the limiting groove 32, and a rotating sleeve is provided on the side of the flange connection tube 33 close to the rotation limiting groove 32. The flange connection tube 33 is rotatably connected to the rotation limiting groove 32 through the rotating sleeve. The flange connection tube 33 is rotatably connected to the rotation limiting groove 32 through the rotating sleeve, so that when the lower gate valve seat 12 is docked with other connecting pipes, there is no need to adjust other objects to align the docking holes of the two connecting flanges. The flange connection tube 33 can be directly rotated. This method is convenient and fast, and is suitable for use in environments with narrow operating space such as fire cabinets, and solves the technical problem of inconvenient connection of the lower gate valve seat 12.

[0032] A step further, such as Figure 2 - Figure 3 The two locking plates 22 are respectively provided on both sides of the connection between the upper gate valve seat 11 and the lower gate valve seat 12, and the two locking plates 22 are slidably connected to the limiting covers 23. The locking assembly 2 replaces the traditional bolt installation, which is not only convenient and fast, but also saves disassembly time. By clamping the two locking seats 21 at the connection between the upper gate valve seat 11 and the lower gate valve seat 12, the upper gate valve seat 11 and the lower gate valve seat 12 are limited to prevent the upper gate valve seat 11 and the lower gate valve seat 12 from separating up and down during use. The limiting cover 23 is limited by the limiting pin 24 inserted on the limiting cover 23. Since the limiting pin 24 passes through the limiting plate 22, the limiting cover 23 can be avoided from separating from the limiting plate 22 during use, thereby solving the technical problem of the split disassembly of the fire gate valve.

[0033] The above solution still has the problem of sealing the connection between the rotation limit groove 32 and the flange connection cylinder 33. Figure 4 As shown: In this solution, a sealing rubber sleeve 34 is embedded in the flange connection tube 33, and the other end of the sealing rubber sleeve 34 is located inside the rotation limit groove 32. The length of the sealing rubber sleeve 34 is greater than the length of the flange connection tube 33. The connection between the sealing rubber sleeve 34, the flange connection tube 33 and the rotation limit groove 32 is sealed to prevent water seepage and leakage due to the rotational connection between the rotation limit groove 32 and the flange connection tube 33 during use.

[0034] The above solution still has the problem of separation between the limit cover 23 and the clamping limit plate 22, such as Figure 3 As shown: In this solution, a limit pin 24 is inserted on the limit cover 23 and passes through the clamping limit plate 22. The limit cover 23 is limited by the limit pin 24 inserted on the limit cover 23. Since the limit pin 24 passes through the clamping limit plate 22, the limit cover 23 can be prevented from separating from the clamping limit plate 22 during use, thereby improving the stability of the device.

[0035] Working principle:

[0036] like Figure 1-4 As shown, first, the regulating mechanism 1, the upper gate valve seat 11 and the lower gate valve seat 12 are assembled, and then the snap-fit ​​seat 21 is snap-fitted on both sides of the connection between the upper gate valve seat 11 and the lower gate valve seat 12, and the two limit covers 23 are slidably connected to the snap-fit ​​limit plates 22 on both sides to limit the two snap-fit ​​seats 21, and then the two limit pins 24 are respectively inserted into the limit covers 23 to limit the limit covers 23. After the installation is completed, the fire gate valve is fixed in the specified position, and then the connecting pipe is aligned with the flange connecting cylinder 33, and the flange connecting cylinder 33 is rotated according to the position of the flange hole on the connecting pipe to align the mounting holes on the two sets of flange parts. After alignment, the installation can be completed by fixing with bolts.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
