Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve sealing structure. Background Art

[0002] A valve sealing structure is a specific structure designed to ensure that the valve can effectively prevent the passage of fluid when closed, achieving a reliable seal. Valves play a key role in controlling the flow of fluid in various fluid systems. If the valve seal is poor, leakage will occur, which can lead to serious consequences. For example, in industries such as chemical, oil and gas, leaked hazardous substances may cause fires, explosions, environmental pollution, and even casualties. A good valve sealing structure can effectively prevent leakage and ensure the safe operation of the system. Existing valve sealing structures have poor installation and sealing practicality, and the device is not stable during use. Therefore, a valve sealing structure is needed.

[0003] The existing valve sealing structure cannot effectively improve the practicality of valve installation sealing during operation, cannot effectively improve the stability of device use, and cannot effectively prevent the problem of valve blockage. Therefore, a valve sealing structure is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a valve sealing structure to solve the problem that the existing valve sealing structure cannot effectively improve the practicality of valve installation sealing when in use, cannot effectively improve the stability of the device, and cannot effectively prevent valve blockage.

[0006] A valve clamping ring is installed at one end of the valve body, a connecting ring rod is installed at one end of the valve clamping ring, and a movable ring is installed at one end of the connecting ring rod.

[0007] A filter screen is installed at one end of the connecting rod, and a limiting hole is installed at one end of the filter screen.

[0008] Preferably, the turning handle forms a rotating structure with the valve body through a turning groove, and the valve stem is threadedly connected to the turning handle.

[0009] Preferably, the valve plug is engaged with the valve stem, and the valve plug forms a lifting structure with the valve body through the valve stem.

[0010] Preferably, the silicone sealing ring is engaged with the valve body through a limiting column, and the limiting column is symmetrically arranged with respect to the central axis of the valve body.

[0014] 1. The utility model is provided with a valve body, a turning handle, a valve stem, a limiting groove, a valve plug, a silicone sealing ring and a limiting column. When the turning handle is rotated, the valve stem drives the valve plug to move up and down in the valve body through the limiting groove to realize the opening and closing of the valve body. Silicone sealing rings are provided at the front and rear ends of the valve body. The silicone sealing ring itself has strong stability and poor thermal expansion and contraction performance, which can effectively seal the connection of the valve body. The limiting column prevents the movement of the silicone sealing ring during the installation of the valve body, which may affect the sealing effect, thereby improving the practicality of the valve installation and sealing.

[0015] 2. The utility model is provided with a valve body, a valve clamp ring, a connecting ring rod and a movable ring. The valve clamp ring is clamped on the valve body, the movable ring is clamped on the rear end of the pipe connection port and sleeved on the connecting ring rod. Bolts are used to fix the position of the movable ring, the valve clamp ring and the connecting ring rod, thereby preventing the problem of falling off caused by excessive pressure on the pipeline and valve, enhancing the connection strength of the valve body and improving the stability of the device.

[0016] 3. The utility model provides a valve body and a filter screen, and sets the filter screen inside the valve body.
