Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of valves, and particularly relates to a stainless steel high-temperature resistant ball valve. Background Art
[0002] A ball valve is a valve whose closing and opening member is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, shunt, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline.
[0003] The existing stainless steel high-temperature resistant ball valves on the market have the following problems when in use:
[0004] 1. When the traditional stainless steel high-temperature resistant ball valve is applied, since the ball valve is mostly used to control fluid transportation on the pipeline, the sealing performance at the connection between the ball valve and the pipeline is very important. However, the sealing structure at the connection of the existing ball valves on the market is relatively single, resulting in poor sealing performance at the connection.
[0005] 2. When most stainless steel high-temperature resistant ball valves are applied, since the ball valve is mostly controlled to open and close by a handle, however, the internal pressure of the ball valve is relatively large during fluid transportation, and it is not easy to close the control handle. Usually, it is necessary to increase the length of the force arm to reduce the force required for closing. And the connection part where the force arm extends is in a weak part, which is easily damaged after long-term use, and its protection for the force arm extension structure is relatively poor. Content of the Utility Model
[0006] The purpose of the utility model is to provide a stainless steel high-temperature resistant ball valve to solve the technical problems raised in the background art.
[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A stainless steel high-temperature resistant ball valve, including a valve body and a handle. Flange plates are provided on both the left and right sides of the valve body. A limit groove is opened on the outside of the flange plate. A sealing ring is arranged inside the limit groove. A fastening ring is fixedly connected to the outside of the sealing ring. A fastening block is welded to the outside of the fastening ring. A perforation is opened on the outside of the fastening block. A fastening bolt is inserted into the perforation. A sealing pipe is installed inside the flange plate.
[0008] Preferably, a sliding groove is opened on the side of the handle. A slider is inserted into the sliding groove. A reinforcing concave plate is fixedly connected to the outside of the slider. A fixing block is installed on the outside of the reinforcing concave plate. A slot is opened on the outside of the fixing block. An inserting block is inserted into the slot. An extension rod is fixedly connected to the side of the inserting block.
[0009] Preferably, a round hole is formed in the outer part of the handle, a shaft rod is inserted into the round hole, the shaft rod penetrates through the inside of the extension rod, a groove is formed in the outer part of the handle, and the extension rod is located inside the groove.
[0010] Preferably, a connecting block is welded to the outer part of the valve body, a threaded hole is formed in the outer part of the connecting block, and a fastening screw is threadedly connected to the threaded hole.
[0011] Preferably, a valve rod is installed on the top of the valve body, a valve seat is fixedly connected to the top of the valve rod, and a handle is installed on the top of the valve seat.
