Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a high-strength, lightweight valve casting. Background Technology

[0002] Existing valve castings are generally connected to water pipes via flanges. High-speed water flow will collide with the inner wall of the water pipe, causing the water pipe to vibrate. Since the valve casting is rigidly connected to the water pipe, the vibration of the valve casting will be amplified or even exacerbated through conduction. The vibration of the valve casting can easily lead to its damage, especially for lightweight valve castings.

[0003] To address this problem, this utility model was developed. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a high-strength lightweight valve casting with simple structure, high strength and shock resistance.

[0005] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a high-strength lightweight valve casting, including a valve body, a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are connected by a shock absorber, a socket block is provided on the first connecting plate, a fixing block is provided at the bottom of the valve body, a socket channel is opened on the fixing block, the socket block passes through the socket channel, and a fixing device is provided on the fixing block to prevent the socket block from disengaging from the socket channel.

[0006] A further improvement is that the fixing device includes a fixing rod that slides through the fixing block. One end of the fixing rod is located in the insertion channel, and the other end of the fixing rod extends out of the fixing block. The insertion block has a fixing channel, and the fixing rod slides through the fixing channel. The fixing block is provided with a backing device that abuts the fixing rod against the fixing channel.

[0007] A further improvement is that the abutting device includes an abutting block, the fixed block has a sliding channel, the fixed rod extends out of the sliding channel, the abutting block is disposed on the fixed rod and located inside the sliding channel, and a spring is sleeved on the fixed rod, one end of the spring resists the abutting block, and the other end of the spring resists the inner wall of the sliding channel.

[0008] A further improvement is that it also includes an adjusting screw, one end of which is threaded through the first connecting plate, and the other end of which is located on the socket block.

[0009] A further improvement is that: the first connecting plate is symmetrically provided with a first connecting ear, the second connecting plate is provided with a second connecting ear, and the two ends of the shock absorber are respectively hinged to the first connecting ear and the second connecting ear.

[0010] Further improvement is that the second connecting plate is provided with a plurality of through holes for expansion bolts.

[0011] Further improvement is that the fixing rod is provided with a pull plate.

[0012] By adopting the foregoing technical scheme, the high-strength light-weight valve casting has the advantages of simple structure, high strength and anti-shock.

[0013] The structure is simple, the strength is high, and the structure can resist earthquakes. When the valve is installed on the pipeline, the socket block and the fixing block are first connected into one. Then the valve is installed on the pipeline and the second connecting plate is abutted against the ground or the wall. When the valve receives a shock impact, the shock is transmitted to the shock absorber, and the shock absorber reduces the shock, so that the valve has an anti-shock function, reduces the shock force, and thus protects the valve body and prolongs the service life of the valve. The socket block and the fixing block are connected, and the shock absorbing part can be removed when not in use, so that the valve body does not occupy space, which is not only convenient for packaging of the valve body, but also convenient for transportation of the valve body.
