Description

Technical Field

[0001] This utility model relates to the field of valve body casting technology, specifically an integral valve body casting. Background Technology

[0002] Molten metal is poured into a pre-prepared mold, and after it cools and solidifies, it is removed, thus producing a valve body casting with a specific shape and size. Valve body castings play a crucial role in fluid piping systems, and their main function is to control the fluid flow rate, pressure, flow direction, and liquid level within the system.

[0003] Chinese utility model patent CN220581785U discloses an integral casting of a ball valve body, including a valve body with a handle mounted on the top. External connecting pipes are located on the left and right sides of the valve body, and a fixing cylinder is located on the outer side of each external connecting pipe. A sealing ring is located inside the fixing cylinder. A lower fixing seat is located below the outer side of the fixing cylinder, and an upper fixing seat is located above the outer side of the fixing cylinder. A lower sealing gasket is located on the upper side of the lower fixing seat, and an upper sealing gasket is located on the lower side of the upper fixing seat. A lower protruding plate is located on the front of the lower fixing seat, and an upper protruding plate is located on the front of the upper fixing seat. A threaded rod is located on the top surface of the lower protruding plate. The lower fixing seat, upper fixing seat, upper protruding plate, threaded rod, and nut are configured to secure the pipe to the fixing cylinder from the outside after the pipe is inserted into the fixing cylinder, thus facilitating the connection and installation of the ball valve body with external pipes.

[0004] To facilitate the connection between the fixed cylinder and the pipeline, the one-piece casting of the ball valve body is provided with a lower fixed seat, an upper fixed seat, an upper convex plate, a lower convex plate, a threaded rod, and a nut. However, the one-piece casting of the ball valve body does not have the function of limiting the nut. In the pipeline system, the fluid may experience certain pressure fluctuations or vibrations. If the nut is not fixed, it may gradually loosen due to these external factors, causing the connection between the upper and lower convex plates to become unstable, reducing the sealing between the pipeline and the valve body, thereby increasing the risk of leakage. This will not only affect the normal operation of the pipeline system, but may also pose a threat to the environment and personnel safety. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integral valve body casting, comprising a valve body body, a handle provided on the top of the valve body body, an anti-slip sleeve provided on the outside of the handle, the anti-slip sleeve and the handle being bonded together, external connecting pipes fixedly provided on both sides of the valve body body, a fixing cylinder fixedly provided on the side of the external connecting pipe away from the valve body body, a lower fixing seat provided on the lower part of the opposite side of the fixing cylinder, an upper fixing seat provided on the upper part of the opposite side of the fixing cylinder, the upper fixing seat and the lower fixing seat being hinged together, an upper protruding plate fixedly provided on the front of the upper fixing seat, the middle of the upper protruding plate being movable The upper convex plate is equipped with a threaded rod, one end of which is fixedly fitted with a hexagonal nut. A rotating seat is movably mounted on one side inside the upper convex plate. The rotating seat is cylindrical and is rotatably connected to the upper convex plate. A sliding cavity is opened inside the rotating seat, and a square plate is movably mounted inside the sliding cavity. The square plate is slidably connected to the rotating seat. An L-shaped rod is fixedly mounted in the middle of the top of the square plate, and a return spring is fixedly mounted on the top of the square plate. The return spring is sleeved with the L-shaped rod. A protective shell is fixedly mounted on one end of the L-shaped rod, and the protective shell is movably inserted with the hexagonal nut.

[0007] Furthermore, the anti-slip sleeve is made of rubber, and the surface of the anti-slip sleeve is provided with anti-slip texture.

[0008] Furthermore, the bottom of the protective shell is provided with a hexagonal groove that matches the hexagonal nut.

[0009] Furthermore, the lower fixing seat has a lower convex plate on its front side, and the surface of the lower convex plate has through holes.

[0010] Furthermore, a sealing ring is provided on the inner wall of the fixed cylinder.

[0011] Furthermore, both the lower and upper fixing seats have sealing gaskets on their inner walls.

[0012] Compared with the prior art, this utility model provides an integral valve body casting, which has the following advantages:

[0013] 1. This integral valve body casting, through the setting of a hexagonal nut, protective shell, L-shaped rod, square plate, return spring, and rotating seat, after the upper and lower convex plates are tightly connected, pull the L-shaped rod away from the upper convex plate. The protective shell and square plate move accordingly, and the return spring deforms. When the bottom of the protective shell is higher than the top of the hexagonal nut, rotate the L-shaped rod. The L-shaped rod drives the square plate to rotate, and the rotating seat rotates inside the upper convex plate until the protective shell is directly above the hexagonal nut. Release the L-shaped rod. Under the elastic force of the return spring, the square plate drives the L-shaped rod and the protective shell to move, thereby allowing the hexagonal nut to be inserted into the hexagonal groove of the protective shell. This achieves the purpose of limiting the hexagonal nut, which helps to reduce the risk of the hexagonal nut loosening or falling off due to external factors such as vibration and pressure fluctuations. It ensures that the connection between the upper and lower convex plates is always stable, improves the safety and sealing of the equipment, and thus ensures the normal operation of the pipeline system.

[0014] 2. This integral valve body casting features an anti-slip sleeve with textured surface. This sleeve enhances the friction between the operator's hand and the handle, making the grip more secure and preventing slippage. This effectively reduces operational difficulty and improves work efficiency. Additionally, the rubber anti-slip sleeve provides some elasticity, acting as a buffer during prolonged gripping or frequent operation of the valve body, reducing the risk of hand injury and improving operator comfort.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model discloses an integral valve body casting, including a valve body body 1. A handle 201 is provided on the top of the valve body body 1, and an anti-slip sleeve 202 is provided on the outside of the handle 201. The anti-slip sleeve 202 and the handle 201 are connected by adhesive bonding. External connecting pipes 203 are fixedly provided on both sides of the valve body body 1. A fixing cylinder 204 is fixedly provided on the side of the external connecting pipe 203 away from the valve body body 1. A lower fixing seat 301 is provided at the lower part of the opposite side of the fixing cylinder 204, and an upper fixing seat 302 is provided at the upper part of the opposite side of the fixing cylinder 204. The upper fixing seat 302 and the lower fixing seat 301 are connected by a hinge. An upper protruding plate 303 is fixedly provided on the front of the upper fixing seat 302, and a threaded rod 304 is movably provided in the middle of the upper protruding plate 303. A hexagonal nut 305 is fixedly installed at one end of the threaded rod 304. A rotating seat 310 is movably installed on one side inside the upper convex plate 303. The rotating seat 310 is cylindrical and is rotatably connected to the upper convex plate 303. A sliding cavity is opened inside the rotating seat 310, and a square plate 308 is movably installed inside the sliding cavity. The square plate 308 is slidably connected to the rotating seat 310. An L-shaped rod 307 is fixedly installed in the middle of the top of the square plate 308. A return spring 309 is fixedly installed on the top of the square plate 308. The return spring 309 is sleeved with the L-shaped rod 307. A protective shell 306 is fixedly installed at one end of the L-shaped rod 307. The protective shell 306 is movably inserted with the hexagonal nut 305.

[0022] Specifically, the anti-slip sleeve 202 is made of rubber, and the surface of the anti-slip sleeve 202 is provided with anti-slip texture.

[0023] In this implementation plan, by setting an anti-slip sleeve 202, when the staff holds the handle 201, the anti-slip texture on its surface enhances the friction between the staff's hand and the handle 201, making the grip more stable and less likely to slip. At the same time, the rubber anti-slip sleeve 202 also has a certain degree of elasticity, which can reduce the risk of hand injury to the staff and improve the staff's comfort.

[0024] Specifically, the bottom of the protective shell 306 is provided with a hexagonal groove that matches the hexagonal nut 305.

[0025] In this embodiment, by setting a hexagonal nut 305 and a protective shell 306, the hexagonal nut 305 can be perfectly embedded in the hexagonal groove of the protective shell 306 to form a tight connection, thereby achieving the limitation of the hexagonal nut 305.

[0026] Specifically, the lower fixing base 301 has a lower protruding plate 401 on its front side, and the surface of the lower protruding plate 401 has a through hole.

[0027] In this embodiment, by setting a lower convex plate 401, the threaded rod 304 passes through the through hole of the lower convex plate 401, thereby realizing the connection between the upper convex plate 303 and the lower convex plate 401, which helps to enhance the overall strength and stability of the valve body casting.

[0028] Specifically, a sealing ring 402 is provided on the inner wall of the fixed cylinder 204.

[0029] In this embodiment, by setting a sealing ring 402, the sealing ring 402 can fill the tiny gaps between the external pipe and the inner wall of the fixed cylinder 204, providing a sealing effect and thus effectively preventing fluid leakage in these gaps.

[0030] Specifically, the inner walls of both the lower fixing seat 301 and the upper fixing seat 302 are provided with sealing gaskets 403.

[0031] In this embodiment, by setting a sealing gasket 403, the sealing between the pipeline and the valve body 1 can be further enhanced, thereby improving the safety of the equipment.

[0032] In use, insert the external pipe into the fixed cylinder 204, then rotate the lower fixed seat 301 and the upper fixed seat 302 until they are closed. Rotate the hexagonal nut 305, and the threaded rod 304 rotates within the upper convex plate 303, with one end entering the through hole of the lower convex plate 401. When the upper convex plate 303 and the lower convex plate 401 are tightly connected, pull the L-shaped rod 307 away from the upper convex plate 303. The protective shell 306 and the square plate 308 move accordingly, and the return spring 309 deforms. When the bottom of the protective shell 306... When the hexagonal nut 305 is above the top, rotate the L-shaped rod 307. The L-shaped rod 307 drives the square plate 308 to rotate, and the rotating seat 310 rotates within the upper convex plate 303 until the protective shell 306 is directly above the hexagonal nut 305. Release the L-shaped rod 307. Under the elastic force of the return spring 309, the square plate 308 drives the L-shaped rod 307 and the protective shell 306 to move, thereby allowing the hexagonal nut 305 to be inserted into the hexagonal groove of the protective shell 306, achieving the purpose of limiting the hexagonal nut 305, so as to improve the tightness of the connection between the pipeline and the valve body 1.

[0033] In summary, this integral valve body casting, through the arrangement of a hexagonal nut 305, a protective shell 306, an L-shaped rod 307, a square plate 308, a return spring 309, and a rotating seat 310, with the upper convex plate 303 and the lower convex plate 401 tightly connected, pulls the L-shaped rod 307 away from the upper convex plate 303, causing the protective shell 306 and the square plate 308 to move accordingly. The return spring 309 deforms, and when the bottom of the protective shell 306 is higher than the top of the hexagonal nut 305, the L-shaped rod 307 is rotated, causing the square plate 308 to rotate. The rotating seat 310 thus rotates within the upper convex plate 303 until the protective shell 306 is directly above the hexagonal nut 305. Releasing the L-shaped rod 307, under the elastic force of the return spring 309, causes the square plate 308 to move, driving the L-shaped rod 307 and the protective shell 306, thereby causing the hexagonal nut 305 to... Inserted into the hexagonal groove of the protective shell 306, the hexagonal nut 305 is limited, which helps to reduce the risk of the hexagonal nut 305 loosening or falling off due to external factors such as vibration and pressure fluctuations. This ensures that the connection between the upper convex plate 303 and the lower convex plate 401 remains stable, improving the safety and sealing of the equipment and thus ensuring the normal operation of the pipeline system. By setting the anti-slip sleeve 202, the anti-slip sleeve 202 with anti-slip texture can enhance the friction between the operator's hand and the handle 201, making the grip more stable and less prone to slipping, effectively reducing the difficulty of operation and improving work efficiency. At the same time, the rubber anti-slip sleeve 202 also has a certain degree of elasticity. When holding for a long time or frequently operating the valve body 1, the anti-slip sleeve 202 can play a buffering role, reducing the risk of hand injury to the operator and improving the operator's comfort.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
