Description
Technical field
The utility model relates to valve technology field, particularly a kind of pneumatic emergency cut-off valve.
Background technique
Pneumatic emergency cut-off valve, it is the one of actuator in automatic system, be made up of many springs pneumatic diaphragn actuating mechanism or floating piston actuator and modulating valve, receive the signal of regulation meter, the cut-out of Controlling Technology fluids within pipes, connection or switching; Pneumatic emergency cut-off valve of the prior art in use often there will be the up and down state do not got stuck smoothly or on the way of flap; if there is the words of the similar situation that gets stuck of flap under some particular job situations; to likely there will be very large security incident; therefore be necessary very much to make certain improvement for this problem, thus avoid the potential safety hazard that may occur in similar product using process.
Summary of the invention
In order to realize background technique requirement, the utility model designs a kind of pneumatic emergency cut-off valve, and this product structure design is simple, uses to stablize secure, also extraordinaryly on flap gets stuck problem, has made corresponding improvement.
Pneumatic emergency cut-off valve, comprises valve body, flap, and described valve body is provided with support, and flap lower end is provided with clamping platform, and clamping platform is connected with spring; Described support is overall to be designed for cylindrical structural, the nose circle face, top of support and parallel coaxial identical with lower rounded end face size, frame bottom is three leg structure designs, three pin are evenly distributed on frame bottom, three pin of frame bottom and valve body vertical welding are connected and fixed, pedestal upper end designs for hook structure, hook structure number is three, be evenly distributed on pedestal upper end, this hook structure is connected with tripod grab, this tripod is grabbed central position and is provided with center hole, and this center hole is connected with flap; Described flap and valve body contact position are provided with seal ring, valve body is also bolted and is provided with cylinder fixed support, this cylinder fixed support is provided with cylinder, cylinder one end is provided with meltable device and gas-tpe fitting, the other end is connected with spanner and drive link, this spanner and drive link are connected with the push rod be arranged in valve body, and link position is provided with sealing cover, and sealing lid is fixedly connected on valve body.
The beneficial effect of this model utility is designed by supporting structure, because three of frame bottom pin are 360 ° of deciles, frame upper hook structure is also 360 ° of deciles, frame upper nose circle face and parallel coaxial identical with lower rounded end face size, three pin of frame bottom utilize instrument to make itself and valve body carry out vertical 90 ° and weld, ensure that pedestal upper end face is parallel with valve body sealing surface, frame upper hook shape is grabbed with tripod and is connected, make hook structure, tripod is grabbed, the center of circle of flap is in same point, make flap smoothly up and down, solve the problem that gets stuck on the way, add valve clack sealing ring and valve body sealing surface close contact, also solve seal leak problem simultaneously.
The meltable device that cylinder is arranged is running in fire or certain external high temperature situation and can melt, cylinder interior and the direct UNICOM of air, cylinder can lose efficacy and cannot work, in this case, the spanner be connected with cylinder and drive link will be positioned at the position propping up flap, flap also just cannot be opened, and the combustible material in valve body is just isolated with external environment, ensure that the further deterioration of field condition.
Can find out that this product structure design can well ensure that the stable effectively work of this pneumatic emergency cut-off valve in sum, the prerequisite of this stable effectively work adds the structural design of meltable device on upper cylinder, product, when running into external environment deterioration and may occurring potential safety hazard, also can well overcome the safety guarantee that may occur realizing in the environment of potential safety hazard field condition at high temperature or chance naked light etc. by the design of the meltable device on product.
