Corrosion-resistant pipe valve structure

Abstract

The invention discloses a corrosion-resistant pipe valve structure. The corrosion-resistant pipe valve structure comprises a valve pipe. The bottom of the valve pipe is connected with a valve body. The valve body is communicated with the valve pipe. The outer side of the valve body is covered with a valve plate which is fixed to the valve body. A limiting plate is transversely arranged on the valve plate and connected to the valve body in a vertical sliding mode. A flange is arranged outside the valve plate. The flange and the valve body are integrally connected. An outer wrapping metal pipe is arranged on the lower surface of the flange and connected to the flange in a clamping mode. The lower surface of the outer wrapping metal pipe is connected with a corrosion-resistant plate. The bottom of the valve plate is arranged on the corrosion-resistant plate. The valve body penetrates through a protection plate to be connected with the corrosion-resistant plate. The corrosion-resistant pipe valve structure is high in corrosion resistance, not prone to damage, low in comprehensive chemical production cost, high in connection constitutive property, and capable of playing a good limiting role and avoiding reaction liquid leakage caused by the deflection phenomenon; meanwhile, the corrosion-resistant pipe valve structure has a certain steel constitutive property, and the service life of the corrosion-resistant pipe valve structure is prolonged.

Description

technical field [0001] The invention relates to a pipe valve structure, in particular to a corrosion-resistant pipe valve structure. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have a wide variety of varieties and specifications, and the valve materials are also various. Some use cast iron valves, some use cast steel valves, and some use stainless steel valves, which are used in chemical industry pipelines. Most of the valves in the country use metal valves. This kind of valve is widely used in the chemical industry because of its strong pressure resistance and high safety factor, but there are also certain defects, such a...

[0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have a wide variety of varieties and specifications, and the valve materials are also various. Some use cast iron valves, some use cast steel valves, and some use stainless steel valves, which are used in chemical industry pipelines. Most of the valves in the country use metal valves. This kind of valve is widely used in the chemical industry because of its strong pressure resistance and high safety factor, but there are also certain defects, such as poor self-regulation and low corrosion resistance. It acts as a limiter, and the combination between the valve and the valve body is poor, which leads to the limitation of use
