Description

Technical Field

[0001] The utility model relates to the technical field of valve installation structures, and particularly relates to a pipeline valve installation structure. Background Technique

[0002] Valves are one of the more common pipeline devices in the prior art. In the prior art, valves are often installed through the following installation methods. First, flange connection is one of the commonly used connection forms in valves. It mainly connects the flanges at both ends of the valve to the flanges on the pipeline through bolts to achieve the purpose of sealing and connection. The advantages of flange connection are firm connection and good sealing performance, and it is applicable to pipeline systems with various pressures and temperatures. During installation, it is necessary to ensure that the end faces of the two flanges are parallel and concentric, and the bolts should be tightened evenly to avoid the gasket from shifting or the valve body from deforming. Second, threaded connection is mainly used for the installation of small-diameter valves. It realizes the connection and sealing of the valve through the screwing of internal and external threads. During installation, it is necessary to ensure the integrity and cleanliness of the threads, and wrap hemp, apply lead paint or use polytetrafluoroethylene thread seal tape on the threads to enhance the sealing effect. The advantages of threaded connection are simple installation and convenient disassembly, but compared with flange connection, its sealing performance and pressure resistance may be slightly inferior.

[0003] However, the valves with flange connection in the prior art have the following drawbacks when in use. That is, when it is necessary to repair the valve plate and the sealing ring structure inside the valve, it is necessary to disassemble the connection flanges at both ends of the valve to have enough space for repairing the valve plate and the sealing ring. In this way, during disassembly and installation, since it is necessary to disassemble the connection flanges on both sides, the operation is relatively troublesome. Therefore, in view of this problem, a pipeline valve installation structure is needed for improvement. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pipeline valve installation structure to solve the problems raised in the above background technique.

A locking nut is movably screwed on the outer surface of the connecting screw through a thread. Through the locking mechanism, the first sealing ring and the second sealing ring can be quickly connected and fixed together.

[0007] Preferably, a notch is provided on the outer surface of the lower end of the second fixing ring. By inserting the connecting screw into the notch and then tightening the locking nut through the thread, the first fixing ring and the second fixing ring can be firmly fixed together by extrusion. At this time, the first sealing ring and the second sealing ring can be firmly clamped together by using the first fixing ring and the second fixing ring to ensure the connection tightness between the first sealing ring and the second sealing ring.

[0008] Preferably, sealing rings are provided on the surfaces of the first sealing ring and the second sealing ring close to each other. When the locking mechanism presses the first sealing ring and the second sealing ring together, the sealing rings can be used to ensure the tightness at the connection between the first sealing ring and the second sealing ring.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a pipeline valve installation structure, including a first connecting pipe 1, a second connecting pipe 2 is arranged on one side of the first connecting pipe 1, a first connecting flange 3 is fixedly arranged on the outer surface of the first connecting pipe 1, a second connecting flange 4 is fixedly arranged at one end of the second connecting pipe 2, a valve housing 5 is fixedly arranged on the outer surface of the first connecting pipe 1 through the first connecting flange 3, a sealing butterfly plate 6 is movably arranged inside the valve housing 5 through a rotating shaft, an operating component 7 is fixedly arranged at the upper end of the valve housing 5, and a maintenance mechanism for facilitating the maintenance of the inside of the valve housing 5 is arranged between the valve housing 5 and the second connecting flange 4. The maintenance mechanism includes a connecting hose 8, a first sealing ring 9, a connecting head 10, and a second sealing ring 11. The connecting hose 8 is fixedly arranged on the outer surface of the valve housing 5, a first sealing ring 9 is fixedly arranged at one end of the connecting hose 8, the connecting head 10 is fixedly arranged on the outer surface of the second connecting flange 4, and a second sealing ring 11 is fixedly arranged on the outer surface of the connecting head 10. A locking mechanism is arranged on the outer surfaces of the first sealing ring 9 and the second sealing ring 11.

[0021] The locking mechanism includes a first fixing ring 12, a second fixing ring 13, a connecting screw 14, and a locking nut 15. The first fixing ring 12 is arranged on the outer sides of the first sealing ring 9 and the second sealing ring 11. One side of the surface of the first fixing ring 12 is movably arranged with the second fixing ring 13 through a rotating shaft. The lower end of the first fixing ring 12 is movably arranged with the connecting screw 14 through a rotating shaft. The locking nut 15 is movably screwed on the outer surface of the connecting screw 14 through a thread. Through the locking mechanism, the first sealing ring 9 and the second sealing ring 11 can be quickly connected and fixed together;

[0022] A notch 16 is opened on the outer surface of the lower end of the second fixing ring 13. By inserting the connecting screw 14 into the notch 16 and then tightening the locking nut 15 through the thread, the first fixing ring 12 and the second fixing ring 13 can be firmly fixed together by extrusion. At this time, the first fixing ring 12 and the second fixing ring 13 can firmly clamp the first sealing ring 9 and the second sealing ring 11 together to ensure the connection sealing performance of the first sealing ring 9 and the second sealing ring 11;

[0023] Sealing rings are arranged on the surfaces of the first sealing ring 9 and the second sealing ring 11 close to each other. When the locking mechanism presses the first sealing ring 9 and the second sealing ring 11 together, this sealing ring can ensure the sealing performance at the connection of the first sealing ring 9 and the second sealing ring 11;

At this time, the weight of the valve housing 5 of this device and the weight of the first sealing ring 9 are borne by the connecting flange. In this way, it can be ensured that the connecting hose 8 bears little weight, and the sealing performance at the joints of the connecting hose 8, the first sealing ring 9, and the second sealing ring 11 can be guaranteed.

[0027] As the device is used, sundries may remain at the sealing part of the sealing butterfly plate 6. At this time, it will affect the closing of the butterfly plate. The traditional method can only remove multiple screws of the connecting flanges on both sides to perform maintenance on the valve body. After cutting off the water source of this device, the locking screw can be rotated through the thread so that the locking screw no longer locks the notch 16. At this time, the first fixing ring 12 or the second fixing ring 13 can be rotated through the rotating shaft, so that the first fixing ring 12 and the second fixing ring 13 are rotated and opened to remove the first fixing ring 12 and the second fixing ring 13. In this way, it is convenient and fast to open the first sealing ring 9 and the second sealing ring 11, and then the connecting hose 8 can be contracted, so that enough space can be opened to facilitate the staff to perform maintenance on the inside of the valve.

[0028] Moreover, when this device is used, the overall operation is convenient and fast. The sealing method in which the first fixing ring 12 and the second fixing ring 13 are pressed tightly to clamp the first sealing ring 9 and the second sealing ring 11 can be opened or closed conveniently and quickly, so as to further facilitate maintenance.
