Description
Technical field
The utility model relates to the air valve in a kind of pulse bag formula deduster deashing injection system, especially a kind of electromagnetic impulse valve with the big flow of two diaphragms.
Background technique
The electromagnetic impulse valve of using in the present pulse bag formula deduster jetting deashing system, structurally, mainly constitute by main valve body, main valve seat, valve gap, big diaphragm, Small diaphragm-piece and solenoid valve, big diaphragm and Small diaphragm-piece are divided into primary pressure chamber with sentinel valve respectively, main counter balance pocket and secondary stress chamber, secondary counter balance pocket, the action of electromagnetic valve Small diaphragm-piece, the action of Small diaphragm-piece causes big diaphragm action again, thereby finishes pressurized air by the process of intake duct to the air outlet channel ejection.China's utility model patent CN2158475Y specification has been done detailed disclosure to structure, the principle of above-mentioned electromagnetic impulse valve.This class electromagnetic impulse valve has the gas port that the pressure chamber that makes the diaphragm both sides and counter balance pocket communicate on big or small diaphragm, when sentinel valve place stand-by state, the Pneumatic pipe cleaner of diaphragm both sides air cavity is crossed gas port and is in the identical state of equilibrium of pressure.Because diaphragm reaches under the spring action on the diaphragm greater than its compression area at pressure chamber at the compression area of counter balance pocket, diaphragm sealing valve port, sentinel valve place closed condition.
Yet, this class electromagnetic impulse valve, in the moment of driving valve, the gas port that the pressurized gas of primary pressure chamber pass on the big diaphragm rushes at atmosphere, its hole wall is subjected to very big surge pressure, under frequent pulsating pressure effect, the gas port on the diaphragm is very easily tired, and tenacity descends, its aperture increases with diaphragm both sides air cavity pressure reduction and becomes big, cause in opening the valve process, the pressure reduction of diaphragm both sides air cavity can't reach the threshold values of diaphragm action, and valve can't be opened, perhaps diaphragm produces vibration, the diaphragm stroke reduces, and winding-up tolerance reduces greatly, thereby shortens dramatically the working life of sentinel valve.
The model utility content
At above-mentioned existing in prior technology problem, the gas port that the utility model is to solve on the big diaphragm is tired easily, and its aperture increases with diaphragm both sides pressure reduction and enlarges, and causes opening short problem of valve, working life.
The utility model is to realize like this, a kind of electromagnetic impulse valve, it comprises a main valve body, a main valve seat, a little valve body, a little valve gap, their end face connections successively, there is its periphery to be fixed on the big diaphragm of main valve seat and main valve body joint between this main valve seat and the main valve body, protection pad on the big diaphragm can get lodged on the intake duct and the valve port between the air outlet channel of main valve body, form principal pressure air cavity that big diaphragm communicates with intake duct on the main valve body and the main balance air cavity between big diaphragm and the main valve seat, between principal pressure air cavity and the main balance air cavity gas port that is communicated with is arranged; Also there is its periphery to be fixed on the Small diaphragm-piece of their joints between little valve body and the main valve seat, secondary stress air cavity between formation Small diaphragm-piece and the main valve seat and the secondary balance air cavity between Small diaphragm-piece and the little valve body, the secondary stress air cavity is communicated with main balance air cavity, this Small diaphragm-piece can be pressed in the secondary stress air cavity and be located on the valve port between the exhaust port of main valve seat, between secondary balance air cavity and the secondary stress air cavity gas port that is communicated with is also arranged; Secondary balance air cavity of may command and the extraneous logical solenoid valve that closes are housed on little valve gap, the gas port that is communicated with between described principal pressure air cavity and the main balance air cavity have be located at reach on the main valve seat wall on the main valve body wall interpenetrate, air guide duct that its two ends communicate with principal pressure air cavity and main balance air cavity respectively.
As further improvement of the utility model, the gas port that is communicated with between described secondary balance air cavity and the secondary stress air cavity have be located on main valve seat wall and the little valve body wall interpenetrate, an air guide duct that its two ends are communicated with secondary balance air cavity and secondary stress air cavity respectively, in this air guide duct, be combined with a removable capillary tube.
Improve as the utility model is another kind of, solenoid valve by be connected an electromagnetism valve head containing sleeve pipe, coil and moving iron core on the little valve gap, at an air chamber that is communicated with secondary balance air cavity between little valve body and the little valve gap, this air chamber vent hole that is located on the little valve body that communicates with the external world is constituted, moving iron core front end plug in the described electromagnetism valve head passes little valve gap and puts in the described air chamber, can be pressed on the described vent hole aperture.
After adopting the utility model structure, because having on the main valve of being located at body wall and the main valve seat wall, the gas port that the principal pressure air cavity is communicated with main balance air cavity interpenetrates, the air guide duct that its two ends are communicated with principal pressure air cavity and main balance air cavity respectively, this duct is in the main valve body and main valve seat that metallic material makes, its pore size in use can remain stablize constant, thereby avoided the prior art gas port to open big diaphragm at rubber material, its aperture enlarges with the increase of both sides pressure reduction after repeatedly using, the phenomenon that causes driving valve takes place, and has prolonged the working life of big diaphragm and sentinel valve; Because having, the gas port that Small diaphragm-piece both sides air cavity is communicated with is located on little valve body wall and the main valve seat wall air guide duct of interpenetrating, communicating with Small diaphragm-piece both sides air cavity respectively, and be combined with removable capillary tube in this duct, thereby Small diaphragm-piece only need be born the keying work of valve port, can loosen the requirement to its material; During closing valve, because of the pressurized gas of secondary stress air cavity flow to secondary balance air cavity from the air guide duct that connects rapidly, Small diaphragm-piece can not produce when close port and flutter, and it is stable to close valve performance; Adopt the capillary tube of different inner diameters, can be fit to different working pressures and response time, enlarged application area.
