Abstract
The invention provides an electromagnetic pulse valve adopting a rolling valve plate, which comprises a valve body; the rear part of the valve body is provided with a throttle orifice; the rear side of the valve body is connected with a valve cover of which the rear part is provided with a vent hole; and an electromagnetic head is arranged in the vent hole. The electromagnetic pulse valve is characterized in that: the rolling valve plate is arranged at the output end of the valve body, and divides the valve body into a rear gas chamber and a front gas chamber; a small membrane is arranged between the vent hole and the rear gas chamber; and the rolling valve plate and the rear side of the small membrane are respectively provided with a first pressure spring and a second pressure spring. The structure of the electromagnetic pulse valve is improved, so the electromagnetic pulse valve increases jetting amount, reduces volume, can resist high temperature and corrosion, and improves servicelife greatly.
Description
Technical field
The present invention relates to a kind of electromagnetic impulse valve that adopts rolling valve plate to substitute diaphragm, belong to the electromagnetic impulse valve technical field.
Background technique
The electromagnetic impulse valve that in pulse bag type dust collector, uses at present, as shown in Figure 1, be the electromagnetic impulse valve structural representation that in pulse bag type dust collector, uses at present, described electromagnetic impulse valve is by Electrical heads 1, second holddown spring 2, Small diaphragm-piece 3, rear gas chamber 4, preceding air chamber 5, vent hole 6, output terminal 7, elastomer diaphragm 8, throttle orifice 9, valve gap 10, the valve body 11 and first holddown spring 18 are formed, valve body 11 rear portions are provided with throttle orifice 9, valve body 11 rear sides connect valve gap 10, valve gap 10 rear portions are provided with vent hole 6, be provided with Electrical heads 1 in the vent hole 6, elastomer diaphragm 8 is located at the output terminal 7 of valve body 11, and valve body 11 is divided into rear gas chamber 4 and preceding air chamber 5, be provided with Small diaphragm-piece 3 between vent hole 6 and the rear gas chamber 4, elastomer diaphragm 8 and and the rear side of Small diaphragm-piece 3 be respectively equipped with first holddown spring 18 and second holddown spring 2.
When electromagnetic impulse valve was ventilated, pressurized air entered rear gas chamber 4 through throttle orifice 9, air pressure compressing elastomer diaphragm 8 displacement forward of rear gas chamber 4, and the output terminal 7 of the sealing gasket shutoff valve on the diaphragm 8 is closed electromagnetic impulse valve.
When the control electrical signal drives Electrical heads 1, the venting that is opened of the vent hole 6 of rear gas chamber 4, rear gas chamber's 4 rapid decompressions are moved after making elastomer diaphragm 8, and sealing gasket is the output terminal 7 of shutoff valve no longer, makes the electromagnetic pulse opening of valves.
Because elastomer diaphragm 8 outer ring parts are clipped between valve gap 10 and the valve body 11 and are fixed, core is under the effect of gas pressure, the back displacement before death of the elastomeric products of dependence rubber realizes the opening and closing of pulse, therefore the aperture of valve is restricted, the winding-up amount of valve can't be improved, and boundary dimension can't be dwindled.Because electromagnetic impulse valve needs frequent switch, elastomer diaphragm is deflection repeatedly several times to tens times in one hour, and was subjected to the erosion of temperature and chemical gas very easily to cause damage.
Summary of the invention
The purpose of this invention is to provide that a kind of winding-up amount is big, volume is little and high temperature resistant and corrosion protection, long service life, the electromagnetic impulse valve of brand new.
In order to achieve the above object, technological scheme of the present invention provides a kind of electromagnetic impulse valve that adopts rolling valve plate, comprise valve body, the valve body rear portion is provided with throttle orifice, the valve body rear side connects valve gap, the valve gap rear portion is provided with vent hole, be provided with Electrical heads in the vent hole, rolling valve plate is located at the output terminal of valve body, and valve body is divided into rear gas chamber and preceding air chamber, be provided with Small diaphragm-piece between venting and the rear gas chamber, rolling valve plate and and the rear side of Small diaphragm-piece be respectively equipped with first holddown spring and second holddown spring, it is characterized in that, be provided with the guiding ball between described rolling valve plate and the rear gas chamber's sidewall, the rolling valve plate middle part is provided with coupking shaft, and coupking shaft is connected with the linear bearing of being located at rear gas chamber's rear sidewall.
The present invention adopts the rolling valve body to substitute original elastomer diaphragm, rolling valve plate adopts aluminum alloy or macromolecular material to make, the center is provided with joining shaft and is inserted in linear bearing, the valve plate limit is provided with the guiding ball, guarantee rolling valve plate scroll forward and backward under the effect of air-flow, realize the opening and closing of electromagnetic impulse valve.Because the displacement of rolling valve plate is without limits, guarantee the enough apertures of electromagnetic impulse valve of all size, spray volume is big, its boundary dimension of electromagnetic impulse valve that adopts rolling valve plate with adopt diaphragm 3 " valve is the same when big or small, " the winding-up amount of diaphragm valve that can reach 4.Size of valve that the winding-up amount of the electromagnetic impulse valve of employing rolling valve plate is equivalent to adopt diaphragm electromagnetic impulse valve 3 " during the winding-up amount, its boundary dimension has only the diaphragm of employing electromagnetic impulse valve 2 " therefore more adapts to the supporting needs that large-scale long bag pulse bag type dust collector develops.The heatproof of rolling valve plate and the raising of Corrosion Protection simultaneously, also improve greatly working life, and be 1,000,000 the working life of high-quality diaphragm, and can reach more than 5,000,000 times the working life of rolling valve plate.
Description of drawings
The electromagnetic impulse valve structural representation of Fig. 1 in pulse bag type dust collector, using at present;
Fig. 2 is for adopting the electromagnetic impulse valve structural representation of rolling valve plate;
Fig. 3 is the enlarged view of rolling valve plate.
Embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
As shown in Figure 2, for adopting the electromagnetic impulse valve structural representation of rolling valve plate, described electromagnetic impulse valve is by Electrical heads 1, second holddown spring 2, Small diaphragm-piece 3, rear gas chamber 4, preceding air chamber 5, vent hole 6, output terminal 7, rolling valve plate 12, throttle orifice 9, and valve gap 13, valve body 14, joining shaft 15, linear bearing 16, guiding ball 17 and first holddown spring 18 are formed.
Valve body 14 rear portions are provided with throttle orifice 9, valve body 14 rear sides connect valve gap 13, valve gap 13 rear portions are provided with vent hole 6, be provided with Electrical heads 1 in the vent hole 6, it is characterized in that, rolling valve plate 12 is located at the output terminal 7 of valve body 14 and valve body 14 is divided into rear gas chamber 4 and preceding air chamber 5, is provided with Small diaphragm-piece 3 between vent hole 6 and the rear gas chamber 4, rolling valve plate 12 and and the rear side of Small diaphragm-piece 3 be respectively equipped with first holddown spring 18 and second holddown spring 2.
