Description

Corrosion-resistant valve suitable for corrosive medium Technical Field The utility model relates to the technical field of corrosion-resistant valves, in particular to a corrosion-resistant valve suitable for corrosive media. Background The corrosion-resistant valve resists chemical corrosion through special materials or structural design, ensures the stability and the service life of the valve in a severe medium environment, is specially used for controlling a pipeline control device for the liquid flow of corrosive media such as chemical strong acid, and realizes the functions of diversion, stopping, adjustment and the like by changing the section or the direction of a flow channel. Through retrieving, chinese patent "a corrosion-resistant gate valve" authorizes bulletin number "CN221628884U" through fixed plate, extension spring, slide bar, handle, axis of rotation and fixture block mutually support, realized that the filter screen is installed in the gate valve body, and then made the filter screen filter the impurity in the fluid to can reduce their direct contact to the inside material of gate valve, improve the corrosion resistance of gate valve. In the above application, because the extension spring has elasticity, can produce vibration force in the flow of the fluid in the gate valve and transmit to the filter screen surface, lead to extension spring and fixture block to produce easily and rock, and then influence the stability of filter screen in the gate valve to influence the corrosion resistance to the gate valve inside. Disclosure of utility model Based on this, it is necessary to provide a corrosion-resistant valve suitable for corrosive media against the problem that the filter screen is unstable in the gate valve, thereby affecting the corrosion resistance inside the gate valve.
