Description

Valve pipeline sealing structure

Technical Field

The utility model relates to the technical field of pipeline control valves, in particular to a valve pipeline sealing structure.

Background Art

Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. 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. Pipelines are mainly used to transport gases or liquids, such as water and natural gas. Common connection devices for pipelines and valves have simple structures and poor sealing performance, and are prone to dripping and pulling off. A sealing structure is required to seal the valve and the pipeline.

DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the embodiments:

Example 1

As shown in Figures 1-5, the utility model provides a valve-pipe sealing structure, a valve 1, a pipe 2 is detachably installed on the left side of the valve 1, a pipe 2 is detachably installed on the right side of the valve 1, a fixing unit is provided at the connection points on both sides of the valve 1, a sealing unit is provided inside the fixing unit, the fixing unit includes a clamping groove 22 provided on the outer surface around the connection ends of the pipes 1 and 2, a positioning hole 23 is provided on the inner bottom end of the clamping groove 22, a connecting sealing ring 11 is fixedly installed on the outer surface of the connection points at both ends of the valve 1, a fixing pin 13 is fixedly installed inside the surrounding of the connecting sealing ring 11, a sliding groove 132 is provided on the inner walls on both sides of the fixing pin 13, and a fixing pin 132 is fixedly installed on the upper and lower ends of the inner part of the sliding groove 132 There is a sliding vertical rod 133, and a positioning column 134 is movably provided on the bottom end of the fixed pin 13, and the bottom end of the positioning column 134 is movably inserted into the inside of the positioning hole 23, and a moving plate 135 is fixedly connected to the top of the positioning column 134, and sliding blocks 136 are fixedly connected on both sides of the moving plate 135. The sliding blocks 136 are slidably sleeved on the outer surface of the sliding vertical rod 133, and a piston column 137 is fixedly installed on the top of the moving plate 135. The other end of the piston column 137 passes through the top of the fixed pin 13, and the other end of the piston column 137 is fixedly connected to an extrusion plate 138. The top of the moving plate 135 is located on the outer surface of the piston column 137 and a return spring 139 is provided, and the other end of the return spring 139 is fixedly installed on the inner top of the fixed pin 13.

Furthermore, the pipe 1 2 and the pipe 2 3 are respectively engaged and connected on both sides of the valve 1. Since the outer surface of the pipe body connection is provided with a snap-in groove 22, when the pipe is inserted into the interior of the connecting sealing ring 11, the pipe can push the positioning column 134 to move, causing the positioning column 134 to shrink to the interior of the fixed pin 13, so that the moving plate 135 slides on the outer surface of the sliding vertical rod 133 to compress the reset spring 139. When the pipe and the inner wall of the connecting sealing ring 11 are tightly combined, the positioning column 134 is reset under the elastic force of the reset spring 139, and abuts against the interior of the positioning hole 23, so that the pipe and the valve 1 are fixedly installed. When disassembling, the extrusion plate 138 is lifted upward to cause the piston column 137 to drive the moving plate 135 to move upward, so that the positioning column 134 is separated from the positioning hole 23, and the connection can be released.

Example 2

As shown in Figures 1-5, on the basis of Example 1, the utility model provides a technical solution: preferably, the sealing unit includes a sealing groove 12 arranged inside the connecting sealing ring 11 at the connection between the two sides of the valve 1, and a sealing groove 2 14 is opened on the inner wall of the connecting end of the connecting sealing ring 11, and the connection between the pipe 1 2 and the pipe 2 3 is fixedly connected with a rubber sealing ring 21, and the rubber sealing ring 21 is movably clamped in the inside of the sealing groove 12, and a rubber ring 24 is fixedly sleeved on the outer surface of the pipe 1 2 and the pipe 2 3, and the rubber ring 24 is movably clamped in the inside of the sealing groove 2 14.

Furthermore, after the connection, the rubber sealing ring 21 at the front end of the pipe is engaged with the sealing groove 12, and the connection of the pipe is squeezed, causing the rubber sealing ring 21 to expand, thereby achieving the effect of sealing the gap. The rubber ring 24 on the outside of the pipe is engaged with the inside of the sealing groove 2 14, further sealing the outer connection gap.

The following is a detailed description of the working principle of the valve pipeline sealing structure.

As shown in Fig. 1-5, when in use, the pipe 1 2 and the pipe 2 3 are respectively engaged and connected on both sides of the valve 1. Since the outer surface of the pipe body connection is provided with an engaging groove 22, when the pipe is inserted into the inside of the connecting sealing ring 11, the pipe can push the positioning column 134 to move, causing the positioning column 134 to shrink to the inside of the fixed latch 13, so that the moving plate 135 slides on the outer surface of the sliding vertical rod 133 to compress the reset spring 139. When the pipe and the inner wall of the connecting sealing ring 11 are tightly combined, the elastic force of the reset spring 139 causes the positioning column 134 to move. 134 is reset and abuts against the inside of the positioning hole 23, so that the pipeline and the valve 1 are fixedly installed. When disassembling, the extrusion plate 138 is lifted upward to prompt the piston column 137 to drive the moving plate 135 to move upward, so that the positioning column 134 is separated from the positioning hole 23, and the connection can be released. After the connection, the rubber sealing ring 21 at the front end of the pipeline is engaged with the sealing groove 12, and the connection of the pipeline is squeezed to cause the rubber sealing ring 21 to expand, so as to achieve the effect of gap sealing. The rubber ring 24 on the outside of the pipeline is engaged with the inside of the sealing groove 2 14, so as to further seal the outer connection gap.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
