Description
Technical field
The utility model relates to the gas source valve in pneumatic transport equipment, specifically can prevent gas backflow and can become a kind of automatic suberization valve of bolt by self-choke.
Background technique
Geldart-D particle starts from 19 century Britain and utilizes pipeline that mail is done Geldart-D particle, and the Geldart-D particle application area expansion of 20th century, is widely used in industry and agricultural.In history, internal cover type Pneumatic conveyer has been invented by Germany, Switzerland releases by-pass pneumatic conveying device, and Britain develops pulse air-sword type feedway, Japanese invention pulsed and ball feedway.These inventions and innovation bring a brand-new stage into the Pneumatic Conveying Technology of bulk material.Current Pneumatic Conveying Technology is used more widely, but the not enough plugging problem of source of the gas occurred in extra long distance conveying, improve bleed pressure material rare source of the gas waste problem, never solved well.Such as there will be refluence phenomenon when pipeline internal air pressure is larger than bleed pressure, or in delivery line, there is no pressure and the gas in source of the gas is run off in a large number, cause energy waste.
Summary of the invention
The purpose of this utility model, is exactly for solving prior art Problems existing, and devises a kind of automatic suberization valve, efficiently solves high-altitude or buried under ground because of the not enough plugging of the long bleed pressure of fed distance, material very few source of the gas waste problem.
The technical solution of the utility model is: a kind of automatic suberization valve, comprise the gas that gas is arranged in power conveying on air supply pipe and have valve body, valve body top be provided with suction port, bottom is provided with air outlet, gas automatic suberization mechanism is provided with in described valve body, described automatic suberization mechanism comprises the piston assembly being arranged on valve inner, surrounds manual tune chamber, automatic suberization chamber and automatic anti-down chamber, be communicated with between each chamber by throttle pipe between described valve body and piston assembly; Described manual tune chamber is positioned at suction port place, is provided with the small piston of piston assembly in manual tune chamber, and small piston is connected with large piston by connecting rod; Described automatic suberization chamber is arranged on connecting rod place, and automatic anti-down chamber is arranged on the below of large piston; Be provided with main air vent between described connecting rod and valve body, main air vent is communicated with manual tune chamber and automatic suberization chamber; The below in described automatic anti-down chamber is provided with check valve, is air outlet below check valve.
In order to realize sealing, the lower end of described main air vent is provided with Sealing, Sealing and connecting rod fitted seal.
The lower surface of described small piston is provided with Sealing and can coordinates with valve body and sealed by main air vent.
The top active chamber of described large piston is provided with the relief tube be communicated with ambient atmosphere.
Be provided with spring in described manual tune chamber small piston is compressed.
The side in described manual tune chamber connects throttle pipe, and throttle pipe is provided with the throttling bolt of adjust flux.
Described check valve is provided with Returnning spring and spherical valve core.
The beneficial effects of the utility model draw by such scheme: owing to being provided with manual tune chamber, automatic suberization chamber and automatic anti-down chamber in valve body, can according to the pressure of each chamber, automatically regulated the gas output of pipeline by piston, under the pressure of each spring, go out air intake when being normally failure to actuate and be in closed condition.When conveyance conduit internal pressure increases, check valve spring action pressure increase advances spherical valve core close port, each chamber forms an airtight space, suction port increasing suction pressure is opened along with interior pressure increasing piston assembly is pushed ahead, when suction pressure is greater than check valve spring pressure, promotes spherical valve core and move and open valve port conveyance conduit is pressurizeed.When valve internal structural failure, the normal operation in order to equipment can be opened suction port temporarily by top handwheel and be maintained operation.The technical program can be more greatly put only gas backflow in delivery pipe internal pressure, and can when delivery pipe does not have material automatic suberization, reduce unnecessary gas waste, be conducive to economizing on resources, reduce shipment and delivery cost.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is manual tune chamber, and 2 is automatic suberization chamber, 3 is automatic anti-down chamber, and 4 is valve body, and 5 is pressure gauge, 6 is air outlet, and 7 is check valve, and 8 is Sealing, 9 is small piston, and 10 is connecting rod, and 11 is large piston, 12 is suction port, and 13 is main air vent, and 14 is relief tube, 15 is handwheel, and 16 is throttling bolt.
