Abstract
This invention relates to one wind sealed valve, which opens gas hole on wall connected to one gas source, wherein, there is one connection door on tube channel with door area larger then tube section area; the door can rotate around axis; the tube wall seals door and axis inside tube; under normal status and self gravity, the door is vertical down tightly sticking to open clamped at tube open; the sealed back door and bottom have one inclination angle A larger than zero and less than ninety degrees.
Description
Technical field
The present invention relates to the sealed valve of master-slave pipeline changing in the pipeline logistics transmission field.
Background technique
The master-slave pipeline changing of present logistics transmission field adopts commutator, and its complex structure is realized trouble, the rate of fault height.
Summary of the invention
In order to overcome complex structure in the existing logistics transmission field master-slave pipeline changing, realize trouble, the problem that rate of fault is high the invention provides a kind of Pneumatic air-tight valve, and it has realized the opening and closing of pipeline, thereby can realize the conversion of master-slave pipeline.
The present invention solves the scheme that its technical problem adopts: have pore above tube wall, pore is opened after door is picked up from the pore air draught time, on the tube wall of the stationary axle the other end top of door.Have one and the door that is hinged of tube wall in pipeline, the area of plane of door is greater than the pipeline section area, and door can rotate around the axis, tube wall with door and shaft sealing in pipeline.Door vertically downward, is close to pipeline tapping during normality under the self gravitation active force, and edge is stuck on the pipeline tapping, with seal for pipe joints.There is an angle of inclination A sealing back door and pipeline bottom surface, and angle A is greater than 0 degree, less than 90 degree.Can be during from the pore air draught with door-inhale, the pipeline conducting, conveying barrel can pass through.
Description of drawings
Fig. 1 is the main sectional view of Pneumatic air-tight valve among the present invention.
Fig. 2 is the right elevation of Pneumatic air-tight valve among the present invention.
Fig. 3 is the plan view of Pneumatic air-tight valve among the present invention.
In the drawings, the 1st, pore, the 2nd, tube wall, the 3rd, door, the 4th, axle, the 5th, pipeline tapping, the 6th, edge, the movement locus of arrow 7 expression doors, the 8th, the included angle A that door and pipeline lower wall form during seal for pipe joints.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, have pore (1) in tube wall (2) top, pore (1) can an external source of the gas.Tube wall (2) is sealed in door (3), axle (4) in the pipeline.Door (3) and tube wall (2) are hinged by axle (4), and door (3) can rotate up and down around axle (4), the movement locus of arrow 7 expression doors.During normality, door (3) vertically downward, is close to pipeline tapping (5) under the self gravitation active force, and edge (6) is stuck on the pipeline tapping (5), with seal for pipe joints.The included angle A (8) that door and pipeline lower wall form is spent less than 90 greater than 0 degree.When needs conducting pipeline, source of the gas is from pore (1) air draught, and door (3) moves along the movement locus of arrow 7, and door (3) is picked up, the pipeline conducting, and conveying barrel can pass through pipeline.Thereby utilize wind-force to realize the conducting and the sealing of pipeline.
Claims (2)
1. Pneumatic air-tight valve, it is characterized in that: in pipeline the top be provided with the door and tube wall be hinged, and on top have pore and link to each other with source of the gas, less than 90 degree, the area of plane of door is long-pending greater than pipeline section greater than 0 degree for the included angle A that door forms with tube wall under the deadweight effect.
2. Pneumatic air-tight valve according to claim 1 is characterized in that: door is installed in the pipeline, is hinged with tube wall.
