Embodiment Construction
[0026] Figure 1 to Figure 4 Shown is a pneumatic control valve with anti-clogging installed at the bottom, including a valve core 1, a valve seat 2, and a valve stem 3. The valve seat 2 is welded on the bottom of the container, and the lower end of the valve seat 2 is provided with a cylinder 4. The valve core 1 is fixed on the top of the valve stem 3 through the fastening flange 5 and the stop flange 6. The bottom end of the valve stem 3 is connected with the bottom cylinder 4 through the coupling 7, and the cylinder 4 moves up and down to push the valve stem 3 up and down. Movement and opening and closing of the valve core and the valve seat 2; the valve core 1 is in the shape of a truncated cone, and the valve core 1 is detachably installed on the valve stem 3, and the valve core 1 is made of soft silica gel or other polymer materials into; the valve seat 2 is a circular tubular structure, and the upper part of the nozzle of the valve seat 2 is an inclined downward groove ...

The invention relates to a pneumatic control valve with an anti-blocking plug installed at the lower portion. The pneumatic control valve comprises a valve element, a valve seat and a valve rod; the valve seat is welded to the bottom of a container, an air cylinder is arranged at the lower end of the valve seat, the valve element is fixed to the top end of the valve rod through a fastening flange and a stopping flange, the bottom end of the valve rod is connected with a bottom end air cylinder through a coupler, and the air cylinder vertically moves to push the valve rod to move up and down and pushes the valve element and the valve seat to be opened and closed. According to the pneumatic control valve with the anti-blocking plug installed at the lower portion, the valve element and the valve seat are installed in liquid, the valve seat is welded to the bottom of the container, the valve element is installed at the lower end of the valve rod, and the valve is opened and closed through vertical movement of the valve rod.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a valve for preventing clogging by reaction material sediment or crystallization. Background technique [0002] Valve is an indispensable component in chemical production and other industrial production. Its main function is to control the fluid. Especially in the production of hazardous chemicals, the quality of the valve has a great impact on safety production and production efficiency. In many cases, it is only because the valve switch is ineffective or stuck that it cannot be opened or closed, resulting in an explosion due to uncontrollable pressure. Therefore, the application field and production environment of the valve are very extensive, and it has a great effect on safety. [0003] Generally, the valves are installed outside the container, and the discharge pipe is connected to the valve through the flange. The sealing part between the valve core and the valve seat is of...
