The invention relates to the technical field of valve equipment, in particular to a straight-stroke black water angle valve. The straight-stroke black water angle valve comprises a valve body, a valveelement assembly, a diffusion pipe, a valve seat sleeve, a pressure reduction pore plate and a bushing, wherein a first accommodating cavity, a second accommodating cavity and a third accommodating cavity which communicate with one another in sequence are formed in the diffusion pipe; the valve seat sleeve is assembled in the valve body and the first accommodating cavity, a first valve seat is arranged in the valve seat sleeve, and a first valve cavity is formed in the first valve seat; the pressure reduction pore plate is arranged in the third accommodating cavity, a through hole allowing the second valve seat to penetrate through is formed in the middle of the pressure reduction pore plate, and the second valve seat is provided with a second valve cavity; and the bushing is arranged inthe second accommodating cavity, and the two ends of the bushing correspondingly abut against the first valve seat and the second valve seat to form a pressurizing channel. The high-pressure difference of media in front of and behind the first valve seat can be reduced, scouring of the media to a valve element and the first valve seat is weakened, the service life of the first valve seat and the service life of the valve element are prolonged, the high-pressure difference part of fluid is transferred to the front and back of the second valve seat, and the second valve seat is convenient to disassemble and assemble and easy to maintain and replace.
Description
technical field [0001] The application relates to the technical field of valve equipment, in particular to a straight stroke black water angle valve. Background technique [0002] At present, the angle valve is the angle globe valve. Its structure and characteristics are modified from the ball valve. The difference from the ball valve is that the outlet of the angle valve is at a 90-degree right angle to the inlet. [0003] In the related technology, the black water angle valve is widely used in the field of coal chemical industry, especially in the coal chemical gasification device for the black water and gray water medium of the coal water slurry gasification process, and the powder medium of the dry coal powder gasification process. working conditions. [0004] However, due to the long-term operation of the black water control valve in the medium of high temperature, high pressure and three-phase flow of gas, liquid and solid, the internal parts of the valve are frequent...
