Abstract
The utility model belongs to an elastic pneumatic electromagnetic valve which adopts an upper valve body and a lower valve body, wherein the upper valve body is connected with the electromagnetic valve into a whole. Elastic plunger plug connecting mechanisms are arranged in the valve bodies. When the valve bodies have certain pressure, a pulse controlling instrument sends out a pulse signal to the electromagnetic valve according to certain pulse width, and the elastic pneumatic electromagnetic valve synchronously controls the positive and negative pressure difference according to the signal to be turned on or off and then delivers air into an air jetting pipe so as to achieve the goal of cleaning dust in a cloth bag. The utility model has the characteristics of wide range of operating pressure, long service life, no need of lubrication, no need of maintenance in the period of service life, etc.
Description
The utility model relates to the matching used elasticity air-operated solenoid valve of a kind of and various pulse bag type dust collectors.

The electronic impulse valve that uses on dusting apparatus at present all adopts rubber membrane chip or metallic piston formula on its structure.Because all multifactor influences such as temperature, air pressure, dust concentration, medium purity, the work frequency in the dust removal process, the stifled phenomenon of diaphragm breakage or piston card is serious, cause equipment not run well, brought many troubles, thereby improved the operating cost of equipment greatly to maintenance.Therefore the utility model is for overcoming the problems referred to above, and designed a kind of elasticity air-operated solenoid valve of brand new.
The purpose of this utility model provides a kind of its inner elasticity air-operated solenoid valve that adopts elastic cylinder bulb stopper bindiny mechanism and closed circuit passage.
The utility model is to adopt such method to realize: the elasticity air-operated solenoid valve is two bodies up and down that adopt aluminum alloy to make, and is connected with following valve body by screw on upper valve body, and upper valve body is connected with solenoid valve and becomes one.On valve body, have closed circuit operation passage, and elastic cylinder bulb stopper bindiny mechanism is housed in valve body.When having certain pressure in the valve body, pulse control instrument sends pulse signal by certain pulse width to solenoid valve, and the elasticity air-operated solenoid valve to the air jet pipe conveying gas, thereby reaches the purpose that purifies reverse gas cleaning by the keying of signal synchronization control piston.
The utility model compared with prior art has:
1, range of working pressure is big, can realize low pressure operation, saves the source of the gas power consumption;
2, winding-up efficient height, ash-removal effect is good, can prolong life of bag filter;
3, the closed circuit moving row of controlled airflow has been stopped secondary pollution;
4, can under outdoor low temperature, move, not have dewfall, phenomenon freezes;
5, product is active in one's movements reliably, good stability, general, applicability is strong;
6, post bulb stopper mechanism need not to lubricate, and the life-span is long, need not carry out any maintenance in the Life cycle, has saved the accessory spending, has removed frequent maintenance from.
7, life of product and main frame are synchronous, have greatly improved the recovery rate of utilization rate, utilization ratio and the dust of equipment.
Concrete structure of the present utility model and embodiment are provided by the following drawings;
Fig. 1 is a general structure schematic representation of the present utility model;
