Description

Technical Field

[0001] This utility model relates to the field of flat gate valve technology, and in particular to a flat gate valve installation structure. Background Technology

[0002] In industrial production and various fluid control systems, flat gate valves are widely used as a key fluid control device in many fields such as petroleum, chemical, power, and metallurgy. In their installation structure, the connection between the mounting flange and the external pipeline is a crucial link; the sealing performance and stability of this connection directly affect the normal operation of the entire valve system and the service life of the valve.

[0003] In traditional flat gate valve installation structures, the connection between the mounting flange and external pipeline is typically exposed to the external environment. However, in practical applications, especially under harsh conditions such as humidity and dust, this exposed structure reveals numerous problems. Moisture in humid environments and various corrosive media in dusty environments easily penetrate the connection between the mounting flange and the external pipeline. Moisture intrusion causes corrosion of the metal components at the connection point, reducing the metal's strength and toughness, thus affecting the connection's stability. Corrosive media such as dust may adhere to the connection point, further accelerating the corrosion process and potentially clogging gaps, affecting the valve's normal opening, closing, and sealing performance. These factors combined significantly shorten the valve's service life in harsh environments, increasing maintenance costs and replacement frequency, causing considerable inconvenience and economic losses for the company's production and operations.

[0004] Therefore, it is necessary to design a flat gate valve installation structure. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flat gate valve installation structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flat gate valve mounting structure includes a flat gate valve body. Mounting flanges are provided on both sides of the flat gate valve body. Each mounting flange is equipped with a protective mechanism. The protective mechanism includes two merging protective shells, arranged vertically. A fixing block is fixed to the side wall of the upper protective shell, and a connecting block is fixedly connected to the side wall of the lower protective shell. The side wall of the fixing block has a connecting groove that mates with the connecting block, and a snap-fit ​​component that mates with the connecting block.

[0008] As a further improvement of this utility model, a fixing plate is fixedly connected to the side wall of the mounting flange, a pin is fixedly connected to the side wall of the fixing plate, and a rotating sleeve is fixedly connected to the side wall of the protective shell, the rotating sleeve being rotatably sleeved on the pin.

[0009] As a further improvement of this utility model, two rubber strips are embedded in the inner wall of the protective shell.

[0010] As a further improvement of this utility model, the snap-fit ​​component includes a snap rod that passes through the side wall of the fixing block, the snap rod extending into the interior of the connecting groove, the snap rod being slidably connected to the fixing block, the side wall of the connecting block having a snap hole that mates with the snap rod, and a tension spring being sleeved on the side wall of the snap rod, one end of the tension spring being fixedly connected to the side wall of the fixing block, and the other end of the tension spring being fixedly connected to the side wall of the snap rod.

[0011] As a further improvement of this utility model, the end of the clamp rod located inside the connecting groove is provided with an inclined surface.

[0012] As a further improvement of this utility model, a pull rod is fixedly connected to one end of the clamping rod located outside the fixing block.

[0013] The beneficial effects of this utility model are:

[0014] The protective shells, set at the top and bottom, can be flipped and closed around the pin shaft to cover and protect the connection between the mounting flange and the external pipeline, effectively preventing corrosive media such as water vapor and dust from penetrating into the connection between the mounting flange and the external pipeline, and significantly improving the service life of the valve in humid and dusty environments.

[0015] Utilizing the interlocking design of the fixing block and connecting block, combined with the inclined guide structure of the locking rod and the automatic reset function of the tension spring, the protective shell achieves "one-press locking." When closing, simply bring the protective shell together; the thrust of the connecting block is converted into lateral displacement through the inclined surface of the locking rod. Once in place, the tension spring automatically rebounds and engages with the locking hole, requiring no tools throughout the process. To open, simply pull the lever with one finger for instant unlocking; operation is simple. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A flat gate valve mounting structure includes a flat gate valve body 1. Mounting flanges 2 are provided on both sides of the flat gate valve body 1. Each mounting flange 2 is equipped with a protective mechanism, which includes two merging protective shells 3, arranged vertically. A fixing plate 5 is fixedly connected to the side wall of the mounting flange 2, and a pin 6 is fixedly connected to the side wall of the fixing plate 5. A rotating sleeve 4 is fixedly connected to the side wall of the protective shell 3, and the rotating sleeve 4 is rotatably sleeved on the pin 6. Rotation of the rotating sleeve 4 on the pin 6 allows the protective shell 3 to rotate, facilitating its opening and closing. Two rubber strips 7 are embedded in the inner wall of the protective shell 3 to improve its protective tightness. A fixing block 8 is fixed to the side wall of the upper protective shell 3, and a connecting block 13 is fixedly connected to the side wall of the lower protective shell 3. The side wall of the fixing block 8 has a connecting groove 9 that mates with the connecting block 13, and a snap-fit ​​component that mates with the connecting block 13.

[0024] In this utility model, the snap-fit ​​component includes a snap rod 10 that passes through the side wall of the fixing block 8 and extends into the interior of the connecting groove 9. The snap rod 10 is slidably connected to the fixing block 8. The side wall of the connecting block 13 is provided with a snap hole 14 that mates with the snap rod 10. A tension spring 12 is sleeved on the side wall of the snap rod 10. One end of the tension spring 12 is fixedly connected to the side wall of the fixing block 8, and the other end of the tension spring 12 is fixedly connected to the side wall of the snap rod 10. The end of the snap rod 10 located inside the connecting groove 9 is provided with an inclined surface, and the end of the snap rod 10 located outside the fixing block 8 is fixedly connected to a pull rod 11.

[0025] In use, the flat gate valve body 1 is first connected to the external pipeline via the mounting flange 2. Then, the operator rotates the upper and lower protective shells 3 around the pin 6 until the two protective shells 3 merge to enclose the mounting flange 2 and the external pipeline. At this time, the connecting block 13 is inserted into the connecting groove 9 of the fixing block 8. The side wall of the connecting block 13 contacts the inclined surface of the locking rod 10 and applies a pushing force, forcing the locking rod 10 to overcome the elastic force of the tension spring 12 and slide outward towards the fixing block 8. When the connecting block 13 is fully inserted, the locking rod 10 rebounds under the action of the tension spring 12 and inserts into the locking hole 14 of the connecting block 13, achieving automatic locking. The protective shell 3 can protect the connection between the mounting flange 2 and the external pipeline. When it is necessary to open the protective shell 3, the operator pulls the pull rod 11 outward to drive the locking rod 10 out of the locking hole 14. At this time, the connecting block 13 is unlocked, and the two protective shells 3 can be fully opened by rotating them in the opposite direction.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
