Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball valve technology, and in particular to a slotted high-temperature valve seat ball valve. Background Technology
[0002] A ball valve is a type of valve that controls fluid flow by rotating a ball with a hole. Its main characteristic is that the opening and closing element is a circular or spherical disc, which rotates 90° to achieve the valve's opening and closing function. In order to control fluids under high temperature, high pressure and complex working conditions, a grooved high-temperature seat ball valve is required.
[0003] High-temperature seated ball valves with grooves can be divided into several types, including metal seated ball valves, soft-seal seated ball valves, and movable grooved high-temperature seated ball valves. These different types of grooved high-temperature seated ball valves can meet different needs under high-temperature conditions and ensure the safety and efficient operation of the system. Among them, the movable grooved high-temperature seated ball valve: the valve seat is movable and adjusted by elastic elements (such as O-rings, springs, etc.), providing more flexible sealing capabilities.
[0004] Traditional ball valves typically rely on a simple contact seal between the valve core and the valve body, which has significant drawbacks, such as limited ability to withstand high pressures and prevent leakage. Furthermore, the simple structure of traditional ball valves makes them unsuitable for complex and harsh operating conditions, especially prone to seal failure at high temperatures. This design cannot maintain stability during prolonged and intensive operation; moreover, traditional ball valves, relying solely on valve core sealing, are susceptible to leakage and cannot effectively withstand high pressures. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a slotted high-temperature valve seat ball valve, which aims to improve the problem that ball valves are prone to leakage and cannot withstand high pressure because they only rely on valve core sealing.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a slotted high-temperature valve seat ball valve, comprising:
[0007] Valve body, which is used to support the whole;
[0008] The valve core is rotatably connected inside the valve body, and a handwheel is fixedly connected to the top of the valve core. The valve core is used to control the opening and closing of the valve body.
[0009] The rear valve seat and the front valve seat evenly seal the valve core;
[0010] A sealing ring, used to seal between the rear valve seat and the front valve seat.
[0011] As a further description of the above technical solution:
[0012] The outer wall of the rear valve seat is fixedly connected to the inside of the valve body, and a connecting ring is fixedly connected to the outer wall of the rear valve seat.
[0013] As a further description of the above technical solution:
[0014] A connecting ring two is fixedly connected to one end of the front valve seat, and the connecting ring two is fitted into the rear valve seat.
[0015] As a further description of the above technical solution:
[0016] The connecting ring 1 is fitted into the front valve seat.
[0017] As a further description of the above technical solution:
[0018] The rear valve seat has a second slot inside, and the front valve seat has a first slot inside.
[0019] As a further description of the above technical solution:
[0020] A sealing ring is provided between the rear valve seat and the front valve seat, and the sealing ring is fitted inside the first slot and the second slot.
[0021] As a further description of the above technical solution:
[0022] The outer wall of the valve core is in contact with the inner wall of the front valve seat.
[0023] This utility model has the following beneficial effects:
[0024] In this invention, the front valve seat is fitted into the rear valve seat via a connecting ring 2, and one end of the rear valve seat is embedded into the front valve seat via a connecting ring 1. At the same time, the rear valve seat and the front valve seat are fitted and sealed by a sealing ring. The sealing ring is fitted into a groove 1 on the front valve seat and a groove 2 on the rear valve seat to seal, thereby improving the sealing and connection strength. This solves the problem that ball valves are prone to leakage and cannot withstand high pressure because they only rely on valve core sealing, thus improving the practicality of the ball valve.
