Problems solved by technology

[0002] Ordinary valves are affected by high temperature, and different materials have different expansion coefficients, which makes it difficult to seal the valve body. At the same time, due to the difference in expansion coefficients of different materials, even if it works well at room temperature, the operation and sealing state are completely changed at high temperatures. , its tightness cannot be guaranteed, and its reversing action cannot even be carried out. The existing two-valve group may expand and cause the valve plate to be stuck in a high-temperature environment, and its service life will not be very long.

Abstract

The invention relates to an anti-corrosion high-temperature-resistant corrugated pipe two-valve set which comprises a valve body, a first control valve and a second control valve. The valve body is ofa disc structure, a first port and a second port are arranged in the round outer end of the valve body, the first port and the second port are vertical to each other, the first control valve and thesecond control valve are correspondingly installed to the first port and the second port, and therefore the axis of the first control valve is vertical to the axis of the second control valve; and thesurface of the valve body is coated with an anti-corrosion high-temperature-resistant coating which is composed of a component A and a component B according to the mass ratio being 3:2. The anti-corrosion high-temperature-resistant corrugated pipe two-valve set has the good high temperature resistance and corrosion resistance, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a corrosion-resistant and high-temperature resistant corrugated pipe with two valve groups. Background technique [0002] Ordinary valves are affected by high temperature, and different materials have different expansion coefficients, which makes it difficult to seal the valve body. At the same time, due to the difference in expansion coefficients of different materials, even if it works well at room temperature, the operation and sealing state are completely changed at high temperatures. , its tightness cannot be guaranteed, and its reversing action cannot even be carried out. In the high temperature environment, the existing two valve groups may cause the valve plate to be stuck due to expansion factors, and the service life will not be very long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a corrosion-resistant and high-temperature resistant bellows two-valve...
