Description
(1) technical field
The utility model relates to the block clearing device on a kind of powder conveying pipeline that is applicable to industries such as being installed in flour mill, cement plant, relates to a kind of electromagnetism fast-discharge valve with block clearing function that is installed on the powder conveying pipeline specifically.
(2) background technique
The outlet valve of prior art mostly is piston cylinder operator; in order to prevent piston generation stuck phenomenon, need at work often to its moving element filling lubricant oil, because the adding amount of lubricant oil is wayward; unnecessary lubricant oil regular meeting follows gas and sprays together, causes the pollution of fed sheet of a media.For addressing this problem, mostly prior art is to adopt the method that installs oil sprayer additional to solve pollution problem.But also brought complexity that its rate of fault increase, maintenance cost are strengthened thus because of structure.
In addition, the piston cylinder operator outlet valve of prior art is in its working procedure, and the powdery medium in the pipeline also inevitably can enter in the piston cylinder, not only can increase the weight of wearing for piston, influences its working life, also can directly have influence on outlet valve explosive force.
(3) summary of the invention
The purpose of this utility model provide at above-mentioned deficiency of the prior art just a kind of simple in structure, cheap for manufacturing cost, rate of fault is low, exhaust is fast, explosive force produces the electromagnetism fast-discharge valve of pollution by force and not.
The purpose of this utility model can realize by following measure:
Electromagnetism fast-discharge valve of the present utility model comprises valve body, described valve body comprises the hollow cylindrical exhaust cavity, around the air-inlet cavity of exhaust cavity setting, the air inlet mouth of pipe that is connected with air-inlet cavity, the communications ports of described air-inlet cavity and exhaust cavity is pressed with a seal isolation diaphragm by valve gap, be provided with the diaphragm stage clip in the balance air cavity that is made of jointly seal isolation diaphragm and valve gap, the seal isolation diaphragm is provided with the vent that is communicated with air-inlet cavity and balance air cavity; Be processed with the counterbore that is used to install seal membrane on the last plane of described valve gap, in this counterbore, be processed with air flue that is communicated with the balance air cavity and the air outlet flue that is connected with atmosphere; Described seal membrane is fitted in the counterbore by upper press cover, upper press cover is provided with spring chamber and is communicated with the relief hole of spring chamber, one solenoid valve is installed on the relief hole, at the spring chamber that is positioned at above the seal membrane diaphragm stage clip is housed, offers the vent that is communicated with spring chamber with air flue opposite position place at seal membrane.
The diaphragm of seal isolation described in the utility model is imitative disc structure, its intermediate portion that is similar at the bottom of the dish is the sandwich structure that has hard material, this part matches with the annular top surface of exhaust cavity, constitutes sealing pair, and its dish edge partly seals on the annular top surface that is pressed in air-inlet cavity.
Two air flue and air outlet flues that are connected with atmosphere that are positioned at the counterbore center position that are communicated with the balance air cavity about being processed with in the described counterbore; Seal membrane with about an air flue opposite position place in two air flues offer the vent that is communicated with spring chamber; The seal isolation diaphragm is provided with a vent that is communicated with air-inlet cavity and balance air cavity.
Working principle of the present utility model is as follows:
The air inlet mouth of pipe in the utility model is connected with gas holder, and exhaust cavity is connected with conveyance conduit by the adpting flange of its lower end.Gas holder is inflated to air-inlet cavity by the air inlet mouth of pipe during work, because the air pressure in the gas holder is lower than the pressure of diaphragm stage clip, seal isolation diaphragm (big diaphragm) can not be backed down, a spot of gas then enters the balance air cavity that is positioned at seal isolation diaphragm top by the vent of the connection air-inlet cavity that is provided with on the seal isolation diaphragm and balance air cavity, after forming certain pressure, gas will enter in the spring chamber by the vent on air flue on the valve gap and the seal membrane (Small diaphragm-piece) and form certain pressure, the epicoele of (big diaphragm) and seal membrane (Small diaphragm-piece) sealing surface is all greater than the cavity of resorption of sealing surface because the seal isolation diaphragm, under the effect of the gentle pressure of diaphragm stage clip, make air-inlet cavity, balance air cavity and spring chamber three chambeies are in pressure balance all the time, that is to say that outlet valve is in closed condition (normally off) all the time.
When the needs exhaust, open solenoid valve, make pressure release in the spring chamber, make between spring chamber and the balance air cavity and produce pressure reduction, be arranged in the pressurized gas of balance air cavity then by two air flues about processing on the valve gap this moment, overcome the pressure of diaphragm stage clip, wash seal membrane (Small diaphragm-piece) open and by being positioned at the air outlet flue pressure release in the middle of two air flues, make between balance air cavity and the air-inlet cavity and produce pressure reduction, the pressurized gas that are positioned at air-inlet cavity then can overcome the pressure of diaphragm stage clip, wash seal isolation diaphragm (big diaphragm) open, moment is communicated with exhaust cavity, and, form impact force by the exhaust pipe mouth discharge, realize removing the purpose of powder obstruction in the pipeline.Close solenoid valve afterwards, make outlet valve return to normally off.
The utility model not only has advantage simple in structure, easy to manufacture, with low cost, long service life compared to existing technology, and has characteristics such as sealability is strong, rate of fault is low, exhaust is fast, explosive force is strong.
