Description

Technical Field

[0001] The utility model relates to the technical field of valves, and particularly relates to a valve casting which is convenient to install. Background Art

[0002] A valve is a pipeline accessory used to open and close a pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. A casting is a metal formed object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction, or other casting methods, and after cooling and subsequent processing means such as grinding, an object with a certain shape, size, and performance is obtained.

[0003] The Chinese utility model patent with the authorization announcement number CN221145657U discloses a valve casting which is convenient to install, including a valve casting body and a connecting clamp. The device is tightened by screwing a connecting knob with a connecting head. When disassembling, the connecting knob can be unscrewed in the reverse direction. The device has a novel structure and fast installation, and is suitable for popularization.

[0004] The above solution solves the technical problems proposed in its background art, but there are still certain defects in actual application. For example, the above device realizes the rapid socket connection of the water pipe and the valve casting by embedding a water pipe connecting block into the clamping groove of the connecting clamp, and realizes sealing through the mutual extrusion of the water pipe connecting block and the sealing ring in the clamping groove of the clamp. However, due to the poor connection stability between the water pipe body and the valve casting, when the valve casting is affected by external vibration or water hammer for a long time, the connection between the water pipe body and the valve casting may become loose, thereby reducing the sealing performance between the water pipe body and the valve casting. Content of the Utility Model

[0005] The purpose of the utility model is to provide a valve casting which is convenient to install, so as to solve the problems proposed in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A valve casting which is convenient to install, including a valve body, both sides of the valve body are integrally formed with connecting pipes, and fixing plates are fixed on the pipe bodies of the connecting pipes;

[0007] An annular groove is opened on one side of the connecting pipe, and a first elastic member is fixed in the groove;

[0008] A fixing shaft is fixed on the side surface of the fixing plate, and a clamp is arranged on the shaft body of the fixing shaft.

[0009] Preferably, two second elastic members are fixed at the end of the connecting pipe.

[0010] Preferably, the clamp includes a top clamp and a bottom clamp. Hinge blocks are fixed to the opposite ends of one side of the top clamp and the bottom clamp, and the hinge blocks are movably connected to the fixed shaft;

[0011] The opposite ends of the other side of the top clamp and the bottom clamp are connected by a connecting portion;

[0012] Circular bumps are fixed to the inner circles of the top clamp and the bottom clamp.

[0013] Preferably, the connecting portion includes a top U-shaped block and a bottom U-shaped block. A screw is movably connected to the side surface of the bottom U-shaped block through a pin shaft, and a nut is movably screwed on the rod body of the screw.

[0014] Preferably, the circular bump is made of rubber material.

[0015] Preferably, both the first elastic member and the second elastic member are rubber pads.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] For the valve casting that is convenient to install, a first elastic member, a second elastic member and a clamp are provided. During installation, the nut is rotated, and the circular bump is pressed against the slope on the outside of the circular block. Under this pressing force, the pipeline and the circular block move towards the valve body until the plug is pressed against the first elastic member and the side surface of the circular block is pressed against the second elastic member. Since the pressing force between the circular bump and the slope on the outside of the circular block always exists, and the first elastic member and the second elastic member always have a rebounding force, the circular block and the connecting pipe are stably connected together, thereby improving the sealing performance and connection stability between the pipeline and the valve body.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 - 3 shown, the present utility model provides a technical solution: a valve casting that is convenient for installation, including a valve body 1. Connecting pipes are integrally formed on both sides of the valve body 1. A fixing plate 101 is fixed on the pipe body of the connecting pipe. An annular groove is formed on one side of the connecting pipe, and a first elastic member 102 is fixed in the groove. Two annular second elastic members 103 are fixed at the end of the connecting pipe. In this solution, both the first elastic member 102 and the second elastic member 103 are made of rubber material.

[0024] A fixing shaft 201 is fixed on the side surface of the fixing plate 101, and a clamp 2 is arranged on the shaft body of the fixing shaft 201. As Figure 2 and Figure 3 shown, the clamp 2 includes a top clamp 202 and a bottom clamp 203. Annular protrusions 209 made of rubber material or metal material are fixed on the inner circles of the top clamp 202 and the bottom clamp 203. Hinge blocks 204 are fixed at the relative ends of one side of the top clamp 202 and the bottom clamp 203, and the hinge blocks 204 are movably connected to the fixing shaft 201. In this way, when the top clamp 202 and the bottom clamp 203 are rotated in opposite directions, the top clamp 202 and the bottom clamp 203 rotate around the shaft body of the fixing shaft 201. At this time, the top clamp 202 and the bottom clamp 203 are in an "open" state, so as to facilitate the placement of the pipeline 3.

[0025] The relative ends of the other side of the top clamp 202 and the bottom clamp 203 are connected through a connecting part. Among them, the connecting part includes a top U-shaped block 206 and a bottom U-shaped block 205. A screw rod 207 is movably connected to the side surface of the bottom U-shaped block 205 through a pin shaft, and a nut 208 is movably screwed on the rod body of the screw rod 207. When the pipe body of the pipeline 3 is placed between the top clamp 202 and the bottom clamp 203, when the top clamp 202 and the bottom clamp 203 "close", the screw rod 207 is rotated to be perpendicular to the bottom U-shaped block 205, and then the nut 208 is rotated to fix the pipeline 3.

[0026] For the supplement of this solution, place the pipe 3 between the top hoop 202 and the bottom hoop 203, and move the pipe 3 forward until the insertion block 302 is inserted into the annular groove. Rotate the screw 207 until it is perpendicular to the bottom U-shaped block 205, and then rotate the nut 208. The two top hoops 202 and the bottom hoop 203 move towards each other. At this time, the annular convex block 209 is squeezed against the slope 303 on the outer side of the annular block 301. Under this squeezing force, the pipe 3 and the annular block 301 move towards the valve body 1 until the insertion block 302 is squeezed between the first elastic member 102 and the side surface of the annular block 301 is squeezed against the second elastic member 103. Since the squeezing force between the annular convex block 209 and the slope 303 on the outer side of the annular block 301 always exists, and the first elastic member 102 and the second elastic member 103 always have a rebound force, the annular block 301 and the connecting pipe are stably connected together, thereby improving the sealing performance and connection stability between the pipe 3 and the valve body 1.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
