Abstract
The utility model relates to a valve capable of automatically closing at the instant for a pipeline, which can automatically closing when the pipeline encounters explosion or burst. A flow direction cut-off cover with a door sleeve is mounted at an inner included angle of a valve body, a wing-shaped support rod with a U-shaped reed is mounted at the other end thereof, and a pneumatic piston rod is mounted at the base part of the support rod to be connected with a gas transmitting hole on one side of the valve body. The width, the thickness and the installing angle of the wing-shaped support rod are calculated and determined according to different media. When the pipeline encounters the explosion or the burst, the flow rate in the pipeline increases suddenly, and the wing-shaped support rod floats upwards under the action of the force of fluid and is separated from the supported cut-off cover. The cut-off cover is closed at the instant under the action of the weight and the pressure of the fluid in the pipeline, thereby achieving the purposes of saving energy and chemical raw materials and reducing environmental pollution. The cut-off cover is reset by using a wrench through the door sleeve after the pipeline is maintained; and the wing-shaped support rod is reset and supported under the action of the reed. When in need of closing the valve artificially, the gas transmitting hole is used for gas transmission, and the pneumatic piston rod push the support rod open to close the cut-off cover.
Description
Technical field: the utility model relates to the pipeline moment automatic-closing valve that a kind of liquid, feed channel meet accident and can close automatically moment when explosion causes serious the leakage.
Background technique: existing liquid feed channel valve uses the manual rotary switch mode usually.When pipeline meets with blast or explosion, because the existing pipeline valve shut-in time is long, cause the interior water of pipeline, gas, the wet goods energy or chemical poisonous and harmful raw material to be gushed, not only cause a large amount of wastes of the energy etc. but also caused the severe contamination of environment.
Summary of the invention: at defective that exists in the prior art and deficiency, the utility model provides a kind of semiautomatic control switch valve.When the utility model utilization liquid feed channel meets with blast or explosion, the unit time flow increases suddenly, lifting the fluid mechanics principles such as covering the aerofoil profile strut of damming, cause the flow direction of the installing lid that dams to break away from and support moment and close automatically, to reach energy saving, to reduce technical purposes such as pollution with the tube wall angle.
Technical solution adopted in the utility model is: the flow direction that angle is installed a band door pocket in the valve body lid that dams, and at the other end aerofoil profile strut of a band U type reed is installed, and the transfer port of pneumatic piston rod connection valve body one side is installed at the strut base portion.According to different media, calculate the setting angle of determining aerofoil profile strut scantling and strut.When the liquid feed channel met with blast or explosion, flow increased suddenly in the pipeline, determined that according to calculating the aerofoil profile strut of installing upwards floats, and breaks away from the supported lid that dams under the fluid mechanics effect.Effect following moment of covering at pipeline inner fluid quality and pressure of damming closes.Behind the pipeline maintenance, with spanner by door pocket will dam the lid reset; Under the effect of reed, the support that resets of aerofoil profile strut.When the artificial throttle down of needs, can back down the aerofoil profile strut by pneumatic piston rod the lid that dams is closed from the transfer port gas transmission.
Effective effect of the present utility model is: at experiences such as transport pipe, pneumatic tube, water pipe or chemical pipeline demolitions or pipeline when explosion is seriously managed Lou voluntarily, the utility model energy moment automatic-closing valve, greatly energy saving, prevent the infringement of poisonous and harmful substance and the expansion of environmental pollution to have high economic benefit and social benefit to greatest extent.

Fig. 2 is an A-A sectional drawing of the present utility model
Fig. 3 is a B-B sectional drawing of the present utility model
Fig. 4 is the local figure of C of the present utility model
Among the figure: 1, valve body 2, dam cover 3, aerofoil profile strut 4, U type reed 5, transfer port 6, pneumatic piston rod 7, door pocket
Embodiment: in Fig. 2, when the liquid feed channel met with blast or explosion, flow increased suddenly in the pipeline, and lifting aerofoil profile strut (3) makes it to break away from the supported lid (2) that dams.The lid (2) that dams was closed in effect following moment of pipeline inner fluid quality and pressure.Behind the pipeline maintenance, reset by door pocket (7) lid (2) that will dam with spanner; Under the effect of reed (4), aerofoil profile strut (3) support that resets.When the artificial throttle down of needs, can back down aerofoil profile strut (3) by pneumatic piston rod (6) lid (2) that dams is closed from transfer port (5) gas transmission.
Claims (2)
1. a pipeline moment automatic-closing valve is made up of control switch, the body that dams, and it is characterized in that: the aerofoil profile they sup-port of a band U type reed the flow direction that the angle of band door pocket the installs lid that dams in the valve body.
2. pipeline moment automatic-closing valve according to claim 1 is characterized in that: the lid that dams becomes angle to install with tube wall.
