Description

Technical Field

[0001] The utility model provides a valve, belonging to the technical field of valve equipment, and particularly relates to a valve with strong impact resistance. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

[0003] The valve is a connector in the pipeline, but when the flow of the object to be transmitted is too large, the connection may burst, causing the entire pipeline connection to collapse. At the same time, in this case, if there is an external impact that causes pressure on the side wall of the valve, it may cause uneven pressure from the outside to the inside, and there is also a risk of damage. Utility Model Content

[0011] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0012] The utility model provides a fixing device sleeved on the outside of the valve pipe, and uses a pressure plate that presses down the valve connecting piece to prevent the valve interior from being subjected to excessive impact force and pushing the valve connecting piece open. At the same time, the corresponding connection between the connecting rods on both sides of the pressure plate is used to strengthen the protective pressure on the valve connecting piece.

[0025] like Figure 1 and Figure 3 As shown, a valve with strong impact resistance includes a valve pipe 1, a fixing device 2 connected to the valve pipe 1 through a valve connector 11 located above the valve pipe 1 and sleeved on the outside of the valve pipe 1, and conical connecting pipes 12 are connected to both ends of the valve pipe 1, and a connecting ring 13 sleeved on the outside of the connecting pipe 12 is connected to the end away from the valve pipe 1, and the connecting ring 13 is provided with a plurality of connecting holes 14 evenly distributed and penetrating the connecting ring 13, the diameter of the internal pipe of the valve pipe 1 is larger than the diameter of the internal pipe of the connecting pipe 12, and the internal pipe of the connecting pipe 12 on the side close to the valve pipe 1 is provided with a gentle slope 16, and the fixing device 2 includes pressing plates 21 arranged on both sides of the valve connector 11 and on the upper and lower sides of the valve pipe 1, and corresponding connecting rods 22 are fixedly connected to both sides of the end of the pressing plate 21 away from the valve pipe 1.

[0026] In this embodiment, a fixing device 2 is provided which is sleeved on the outside of the valve tube 1, and a pressure plate 21 which presses down the valve connector 11 is used to prevent the valve interior from being subjected to excessive impact force and pushing open the valve connector 11. At the same time, the corresponding connection between the connecting rods 22 on both sides of the pressure plate 21 is used to strengthen the protective pressure on the valve connector 11. At the same time, the fixing device 2 is sleeved on the outside of the valve tube 1 to share the external impact of the valve tube 1 and stabilize the internal pressure and the connection.

[0027] like Figure 2As shown, the outer sleeve of the connecting rod 22 is provided with a spring 23 fixedly connected to the pressure plate 21, and the other end of the spring 23 is fixedly connected to a sliding fixing plate 24 penetrated by the connecting rod 22, and the side of the sliding fixing plate 24 away from the pressure plate 21 is provided with a limiting member 25 fixedly connected to the connecting rod 22 and having a diameter larger than the connecting rod 22, and a protective plate 26 corresponding to the valve connecting member 11 is provided above the pressure plate 21, and planar limiting surfaces 15 are provided on the left and right side walls of the valve pipe 1, and the internal shape of the sliding fixing plate 24 corresponds to the valve pipe 1 and the limiting surface 15.

[0028] In this embodiment, when the water flows through the inside of the valve tube 1, it first passes through the internal pipeline of the connecting tube 12, and then enters the inside of the valve tube 1 through the gentle slope 16. The increase in the internal diameter increases the water flow cross-section, thereby slightly slowing down the flow rate of the water flow, reducing the pressure on the valve connector 11, and at the same time, the gentle slope 16 plays a transition and buffering role to prevent the water flow from directly impacting the connection between the connecting tube 12 and the valve tube 1; when subjected to external impact, the sliding fixed plate 24 slides under the restriction of the limit surface 15, compressing the spring 23, and playing a certain buffering role; the protective plate 26 can act as a valve switch.

[0029] When in use, first, the valve of the utility model needs to be installed to a predetermined position. This involves connecting the valve tube 1 to the rest of the system through the valve connector 11 above it. Make sure that the valve connector 11 is correctly connected so that the subsequent steps can proceed smoothly; sleeve the fixing device 2 on the outside of the valve tube 1, and make sure that the pressure plate 21 is correctly placed on both sides of the valve connector 11 and the upper and lower sides of the valve tube 1. This helps to protect the valve connector from being pushed open by the impact force when the valve is impacted from inside and outside; install corresponding connecting rods 22 on both sides of the pressure plate 21, and sleeve a spring 23 on the outside of the connecting rod 22. The other end of the spring 23 should be fixedly connected to the sliding fixing plate 24, and make sure that the sliding fixing plate 24 is fixedly connected to the connecting rod 22 through the limiter 25. Such a setting helps to provide additional stability and buffering when impacted; set a protective plate 26 above the valve tube 1 to ensure that it is connected to the valve connector 11 to prevent damage caused by direct impact. At the same time, check whether the limiting surfaces 15 on the left and right sides of the valve tube 1 are in the correct position to facilitate the proper cooperation of the sliding fixing plate 24; after the system is started, the water first flows through the internal pipeline of the connecting tube 12, and then the water flows smoothly to the inside of the valve tube 1 due to the gentle slope 15 of the inclined surface provided inside the connecting tube 12. In this process, the increase in the internal diameter causes the water flow rate to decrease slightly, reducing the direct pressure impact on the valve connector 11, thereby protecting the entire valve structure. Through the above steps, the valve of the utility model can effectively reduce the impact pressure of the internal water flow on the valve itself during use, and at the same time provide additional protection measures against the impact force, ensuring the long-term stability and reliability of the valve.

[0030] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
