Abstract
The mechanically sealed valve has inside the sealed cavity comprising the valve and the pipe wall one door hinged to the pipe wall, one stretched rod fixed to the door and one balance weight fixed to the end of the rod. Shaking the rod can swing the door inwards to seal the pipe or outwards to open the pipe. Normally, drawing the rod downward can seal the pipe, sucking upward can seal the pipe tightly, and sucking downward can open the door and the pipe.
Description
Technical field
The present invention relates to the pipeline logistics transmission field, be used for sealing the sealed valve of transmission pipeline.
Background technology
The sealed valve of transmission pipeline all needs circuit to cooperate master cock at present.
Summary of the invention
The invention provides a kind of sealed valve of pure physical construction.The present invention solves the method that its technical matters adopts: in an annular seal space of being made up of duct wall, in the pipeline of the side of vertical pipeline and duct wall be hinged one, have one and door is fixing and the bar that stretches out at hinge one end of door, fix a counterweight at the end of bar.Jack back can make door wave, salable inwards pipeline, but outwards wave opening conduits.Under the normality, under the gravity of counterweight, downward pull lever, driving gate waves inwards, and closed conduct when not using the branch pipe(tube) at this device place, is bled from the device top, makes seal for pipe joints tighter.When using branch pipe(tube), bleed from this device below, door-inhale to be opened, the transmission body passes through pipeline.
Description of drawings
Figure of description is the sectional structure chart of a kind of mechanically sealed valve among the present invention.
1 is branch pipe(tube) among the figure, the 2nd, and door, the 3rd, bar, the 4th, counterweight, the 5th, annular seal space, the 6th, blower fan, the 7th, axle, the 8th, duct wall, the 9th, transmission body.
The specific embodiment
As shown in FIG., in the annular seal space of forming by duct wall (5), there is door (2) to be connected by axle (7), and has a bar (3) to captive joint, fix a counterweight (4) at the end of stalk with door (2) with duct wall (8).Door can be swung around axle (7).During normality, under the action of gravity of counterweight (4), door (2) swings in the pipeline (1), and pipeline (1) is sealed.When other pipeline uses, upwards air draught, door (2) is inhaled tight more more.When using pipeline (1), blower fan (6) air draught, door is swing outwards, and pipeline (1) is opened, and transmission body (9) is by pipeline (1).Finished the process that a pipeline (1) is closed and opened.
Claims (2)
1. mechanically sealed valve is characterized in that: in an annular seal space, one and duct wall are hinged, and fix a bar on the door, and the other end of bar is fixed a counterweight.
2. a kind of mechanically sealed valve according to claim 1 is characterized in that: door is installed in the pipeline and is hinged with duct wall.
