Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the present invention provides an embodiment: the valve is characterized in that a continuous and deformable cavity is arranged between the valve body (1) and the valve seat (2), the valve seat (2) and the valve plate (3) are in clearance fit before air pressure is applied, the valve plate (3) is fixed through an upper valve rod (5) and a lower valve rod (4), the upper valve rod (5) and the lower valve rod (4) are coaxial with a shaft hole of the valve body (1), and an upper shaft sleeve (6) and a lower shaft sleeve (15) which are used for guiding are arranged on the inner peripheral surface of the valve body (1). The cylinder (12), the gas flow pressure regulating module (13) and the two-position five-way electromagnetic valve (14) are sequentially arranged from inside to outside, are tightly fixed by adopting an elastic gasket and an inner hexagon screw to form a pneumatic actuator together, and the valve plate (3) is in transmission connection with the cylinder (12) through the upper valve rod (5). The valve body (1) is tightly fixed with the air cylinder (12) through an outer hexagon screw (9), a spring gasket (10) and a gasket (11). The pneumatic valve is characterized in that air inlets are formed in two sides of the valve body (1) and are connected with pneumatic connectors of corresponding specifications, the pneumatic connectors connected with two sides of the valve body (1) are connected through 8mm air pipes, three-way pneumatic connectors are arranged in the middle of the 8mm air pipes, the upper ends of the three-way pneumatic connectors are connected with the pneumatic connectors on two sides of the valve body (1), and the left end and the right end of the three-way pneumatic connectors are connected with the pneumatic connectors on two sides of the valve body (1).
When the valve is closed: the external air source is communicated, air enters the air flow pressure regulating module (13) from the air inlet of the two-position five-way electromagnetic valve (14), the air flow and the pressure of the air are regulated by the air flow pressure regulating module (13), the pressure of the outlet air can be determined by the pressure gauge on the air flow pressure regulating module (13), and the regulated air enters the air cylinder (12) and the air pipe with the diameter of 8mm respectively. The valve enters a cylinder (12), and the upper valve rod (5) and the valve plate (3) are driven to rotate through the cylinder (12) so as to enable the valve plate to be closed; the gas entering the 8mm gas pipe through the gas outlet enters a continuous and deformable cavity of the valve body (1) and the valve seat (2) from two sides of the valve body (1) through the 8mm gas pipe, and extrudes the valve seat (2), so that the valve seat (2) and the valve plate (3) are extruded and sealed.
When the valve is closed: the two-position five-way electromagnetic valve (14) cuts off the air source, discharges air, discharges the air in the continuous and deformable cavity of the valve body (1) and the valve seat (2), the valve seat (2) loses the air pressure and recovers the original state, and is separated from the valve plate (3), and meanwhile, the air cylinder (12) drives the upper valve rod (5) and the valve plate (3) to rotate, so that the valve plate (3) is opened.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
