Abstract
The utility model provides a pneumatic automatic dust removing valve which comprises a valve body, a valve plate and an air cylinder. The valve plate is arranged in a valve cavity formed by the valve body. The air cylinder is connected and fixed with the valve body. A piston of the air cylinder is connected with a connection rod which is connected with the valve plate. Blowing holes are arranged in the valve body and nozzles are arranged at the blowing holes and connected with a blowing device. The blowing device comprises a single-direction valve, an electromagnetic valve and a gas source. The electromagnetic valve and the single-direction valve are sequentially arranged from the gas source and the nozzles. Multiple blowing holes are arranged in the valve body and respectively arranged on the circumference of the valve body so that air currents are blown in multiple directions and dust is removed at places where the valve plate passes by. The valve solves the problem that dust accumulates in the cavity body of the valve, enhances stability of a system at work, prolongs service life of the valve and modifies a working state of operation staff who do not need to detach the valve to remove accumulated dust in the cavity body of the valve.
Description
Technical field
The utility model relates to a kind of self ash-cleaning type valve, especially is a kind of air-transport system oneself
The ash-cleaning type valve.
Technical background
In air-transport system, in order to realize the conveying of malleation or negative pressure form, need to arrange the valves such as feeding valve, discharge valve, outlet valve, block clearing valve and switching valve in the system.In use, because it is inner at valve pocket that powder accumulates (or powder is compacted), the valve plate ON/OFF that valve often occurs is not in place, cause on the one hand the valve ON/OFF jitter that puts in place, cause the automatic fluctuation of service of air-transport system, increase operator's Maintenance and Repair workload, also cause certain environment to pollute; In addition, also can cause the shortening in working life of the unreliable and valve of air-transport system work.
For working stability, the reliability that improves air-transport system and the working life that prolongs valve, just must solve the problem of valve cavity inner product ash.
The model utility content
The utility model proposes a kind of self ash-cleaning type valve, not only solved valve cavity inner product ash problem, improve the working life of system works stability and valve, also improved operator's working state, operator generally no longer need to dismantle the dust stratification in the valve cleaning valve cavity.
For solving above technical problem, the technological scheme that the utility model provides is as follows: a kind of self ash-cleaning type valve, and described valve comprises valve body, valve plate and cylinder, described valve plate is arranged in the valve pocket of valve body formation, cylinder and valve body are connected and fixed, and cylinder piston connects connecting rod, connecting rod connection valve plate; Described valve body is provided with injection hole, and nozzle is installed at the injection hole place, and nozzle connects air jet system.
Further, described air jet system comprises one-way valve, solenoid valve and source of the gas, be disposed with described solenoid valve and one-way valve from source of the gas to nozzle, electromagnetic valve realizes the open and close of gas source feed, gas forms the savings of air pressure by one-way valve the time, in a single day one-way valve is opened, and forms jet-stream wind at the nozzle place, realizes highpressure deashing function.
Further, the quantity of injection hole is a plurality of on the described valve body, is separately positioned on the valve body circumference, makes the direction of air flow blowing different, reaches valve plate by the purpose of part free from dust.
This self ash-cleaning type valve that the utility model relates to, simple in structure, make easy for installationly, at valve blowing device is set, be provided with nozzle in valve pocket inside, be provided with air-flow check device one-way valve at gas pipeline, and pass into the source of blowing clearly.
Description of drawings
Fig. 1 is the utility model self ash-cleaning type valve mechanism front view;
Fig. 2 is self ash-cleaning type valve plan view;
Mark is expressed as follows among the figure: the 1-valve body; The 2-cylinder; The 3-nozzle; The 4-one-way valve; The 5-solenoid valve; The 6-source of the gas; The 7-valve plate; The 8-connecting rod.
Embodiment
Shown in Fig. 1-2, the material of self ash-cleaning type valve is antifriction metal (AFM) or pottery, and valve comprises valve body 1, valve plate 7 and cylinder 2, described valve plate 7 is arranged in the valve pocket of valve body 1 formation, cylinder 2 is connected and fixed with valve body 1, and cylinder 2 pistons connect connecting rod 8, connecting rod 8 connection valve plates 7; Described valve body 1 is provided with injection hole, and nozzle 3 is installed at the injection hole place, and nozzle 3 connects air jet system.
Air jet system comprises one-way valve 4, solenoid valve 5 and source of the gas 6,3 are disposed with described solenoid valve 5 and one-way valve 4 from source of the gas 6 to nozzle, solenoid valve 5 controls realize the open and close of source of the gas 6 air feed, gas forms the savings of air pressure by one-way valve 4 time, in a single day one-way valve 4 is opened, form jet-stream wind at nozzle 3 places, realize highpressure deashing function.
The quantity of injection hole can be separately positioned on valve body 1 circumference for a plurality of on the valve body 1, makes the direction of air flow blowing different, reaches valve plate 7 by the purpose of part free from dust.
In addition, the another kind of design attitude of nozzle is, shown in Fig. 1-2, opened 4 injection holes at valve body 1, is provided with in valve body 1 towards the nozzle 3 of different direction winding-up, and each nozzle 3 is introduced the source of the gas 6 of same road winding-up usefulness.When opening valve, 3 pairs of valve plates of nozzle the cavity position that will pass through blow clearly processing, avoid powder to accumulate or be compacted.
The position that nozzle 3 arranges should be able to effectively be blown clearly valve plate 7 and be moved the place, and preferably along the tangent direction setting of valve body 1, it is better to blow clearly effect.
On the gas circuit one-way valve 4 must be set, avoid powder to seal in the source of the gas 6.
Winding-up source of the gas 6 can be introduced separately into, and also can utilize valve control source of the gas.
This self ash-cleaning type valve that the utility model provides has been avoided the generation of valve ON/OFF situation not in place, has reduced artificial clear valve workload and has improved operating conditions, also so that prolonged the working life of valve.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
