Description
Technical field
The utility model relates to a kind of light-duty plate valve, particularly a kind of plate valve that is loaded with pneumostop on built-in flat board.
Background technique
At present, the light-duty plate valve that generally adopts in biopharmaceutical industry comprises upper valve body, following valve body, valve body suction flange, valve outlet flange, valve plate, piston rod, wherein, piston rod is connected by bolt, nut with valve plate, the contacting point of piston rod and valve body seals with Stuffing box, filler and Gland, manual, the electronic and pneumatic three kinds of modes of the normal employing of its opening and closing, the gate valve of this structure is applicable to the material of liquid or solid medium; But for gas medium, when valve plate was in closed condition, because there is a glade plane space cavity inner surface connecting part of the upper valve body of valve plate and flange inlet, gas medium can let out by the packing seal of this gap from flange outlet and piston rod; In addition, also reinforce sealing because the mating face between the upper and lower valve body is the plane, so its sealability is relatively poor by packing ring, bolt, nut; Moreover, when light-duty plate valve is the horizontal position installation, that is this installation is when being horizontal valve plate, in the unlatching or pass closed procedure of valve plate, because valve plate is subjected to the influence of the gravity of own wt generation, valve plate can offset downward to contact with the cavity inner surface of flange outlet port valve body and produce friction, thereby influence the normal unlatching of valve plate, and the while is also damaged valve plate easily.
Summary of the invention
The purpose of this utility model is to provide a kind of light-duty plate valve of pneumatic extruding of good airproof performance.
The purpose of this utility model is achieved in that the light-duty plate valve of a kind of pneumatic crush seal, it comprises: upper valve body, following valve body, described upper and lower valve body surrounds the cavity of a sealing, the valve plate that is connected with the piston rod of piston-cylinder is installed in this cavity, and described upper and lower valve body is provided with the flange that is connected with the cavity both sides; Wherein, the flange import of described flange and flange outlet lay respectively at the both sides of described upper and lower valve body, have the through hole that is complementary with described flange inlet/outlet on the described valve plate away from the piston rod connecting end, it is characterized in that: the internal surface of all upper valve bodies of described flange import ring is provided with the annulus rectangle groove, has and the vertical inlet hole that communicates of described annulus rectangle groove, suction port on the outer surface of all upper valve bodies of described flange import ring; Be placed with seal ring in the described annulus rectangle groove.
The internal surface of described upper valve body is directly dug or be welded on to above-mentioned annulus rectangle groove.
The bottom of above-mentioned seal ring and described annulus rectangle groove is provided with an air chamber.
The sidewall of above-mentioned annulus rectangle groove is provided with a step, and described air chamber is formed on the bottom of this step and described annulus rectangle groove.
Above-mentioned inlet hole, suction port are provided with along described valve plate movement direction, and are positioned at the both sides of described flange import.
Above-mentioned seal ring is an O type rubber seal.
Above-mentioned valve body down is provided with the sterilization hole.
For good seal performance between the upper and lower valve body that makes the light-duty plate valve of pneumatic extruding, the mating face between upper valve body described in the utility model and the following valve body is made as step surface.
When light-duty plate valve is a horizontal position when installing, for the friction of the cavity inner surface that can eliminate valve plate and flange outlet port valve body, prolongation valve plate working life, the internal surface of the valve body in the described flange of the utility model outlet port is provided with gusset.
Above-mentioned gusset is arranged on the movement direction of described valve plate.
Above-mentioned gusset is two or more.
The utility model is owing to be provided with an annulus rectangle groove on the internal surface of flange inlet valve body cavity, and corresponding valve outer surface have with described annulus rectangle groove vertical communicate advance, intakeport; Settle a rubber seal in the described annulus rectangle groove, and leave a space and form air chamber naturally, this air chamber also can be formed by the step of the sidewall setting of annulus rectangle groove and the bottom of described annulus rectangle groove; After valve plate is closed, the pressurized air that produces by the air compressor that is communicated with the suction port pressurization of in described annulus rectangle groove, ventilating, rubber seal in the groove is pressed against valve plate and fits tightly with it under the effect of gas pressure, form pneumatic crush seal therefrom, thereby blocked gas medium by the gap between valve body cavity inner surface and the valve plate, intercepted gas effectively and let out from the packing seal of flange outlet and piston rod; When opening valve plate, only need rubber seal to be separated with valve plate from the intakeport pressure release of bleeding, drive piston rod and valve plate by piston-cylinder then and move and get final product.
Annulus rectangle groove described in the utility model can directly be dug on the internal surface of described flange import ring week upper valve body, also can process the relevant position that is welded on the upper valve body internal surface behind the annulus rectangle groove in addition; After pressurized air enters the annulus rectangle groove by suction port, through air chamber (malleation) O type rubber seal is pushed and to press to valve plate and form sealing, when bleeding (negative pressure) from intakeport, O type rubber seal is left valve plate, return in the groove, air chamber exists all the time, helps the advance and retreat of O type rubber seal.
The sterilization hole that the utility model is provided with on described valve body down is used for the cavity of valve body is reached the sterilization of the follow-up equipment that is communicated with the flange outlet.
The utility model is owing to be respectively arranged with the step that matches each other on the upper and lower valve body at the joining portion of described upper and lower valve body, this step makes the mating face of described upper and lower valve body become a step surface, when upper and lower valve body being reinforced sealing with packing ring, bolt, nut, this step surface can stop the leakage of medium effectively, thereby plays good seal action.
The internal surface of the valve body in the described flange of the utility model outlet port is provided with two or more gusset, setting can overcome effectively like this: the utility model adopts when making the installation that its valve plate is horizontal, the valve plate bottom contacts the frictional force that produces with the cavity inner surface of flange outlet port valve body, thereby guarantee the normal opening and closing of valve plate, also prolonged the working life of valve plate simultaneously.
