Black water coking-preventing impact-resistant shockproof regulating angle valve special for coal chemical industry

Abstract

The invention relates to a regulating angle valve, in particular to a black water coking-preventing impact-resistant shockproof regulating angle valve special for the coal chemical industry, and belongs to the field of fluid control valves. The black water coking-preventing impact-resistant shockproof regulating angle valve comprises a diffusion tube and a valve body, wherein the lower end of the valve body is connected with the diffusion tube through a bolt. An inlet flowing channel is arranged in the valve body, an outlet flowing channel is arranged in the diffusion tube and is communicated with the inlet flowing channel, and the inlet flowing channel is perpendicular to the outlet flowing channel. A valve carrier base is arranged in the outlet flowing channel and is clamped through the diffusion tube and the valve body, and a valve carrier is arranged in the valve carrier base. The black water coking-preventing impact-resistant shockproof regulating angle valve is simple in structure and novel in design, can effectively solve the technical problems that a traditional black water regulating angle valve is easy to coke, poor in impact resistant performance, undesirable in shockproof effect and the like in a use process, is widely applied in sites of customers, and effectively lowers production operation cost of the customers.

Description

technical field [0001] The invention relates to a regulating angle valve, in particular to an anti-coking anti-shock and anti-vibration regulating angle valve for black water special for coal chemical industry, which belongs to the field of fluid control valves. Background technique [0002] The black water regulating angle valve is one of the key equipment in the coal chemical production gasification device, mainly used in the flash evaporation and water circulation system of the gasification section. The medium black water controlled by this type of valve has complex components and contains a large number of solid particles; the medium usually contains corrosive media such as chloride ions, ammonia, potassium salt, hydrogen sulfide or phosphoric acid, and the pressure difference between the front and back of the valve is relatively large, and the working conditions Extremely harsh.

AI Technical Summary

Problems solved by technology

The medium black water controlled by this type of valve has complex components and contains a large number of solid particles; the medium usually contains corrosive media such as chloride ions, ammonia, potassium salt, hydrogen sulfide or phosphoric acid, and the pressure difference between the front and back of the valve is relatively large, and the working conditions extremely harsh

[0003] The traditional black water regulating angle valve usually has the following problems during use: 1. The internal parts of the valve are affected by various factors such as erosion, flashing or cavitation, and the parts are easily damaged and the service life is short. From March to June, the production and operation costs of users have been increased

2. The surface of the valve stem is easy to coke. Coking on the surface of the valve stem will cause the valve to jam, malfunction, and cause leakage at the sealing packing of the valve, which seriously affects the adjustment performance and safety of the valve; 3. The valve works under high pressure differential conditions. , prone to resonance, poor dynamic stability of the valve

4. In the traditional black water regulating angle valve, when the medium flows through the valve, a high-speed eddy current will be generated, which will easily cause the valve core and valve stem to rotate relative to each other; under the double influence of resonance factors, it will easily lead to the loosening or even breaking of the connecting thread of the two.
