Abstract
The utility model relates to a drowned pulse valve which is applied to environment protection industry. The utility model is composed of a valve seat, a small hard core, a large diaphragm, a large hard core, an electromagnetic valve, a small valve cover, a large valve cover, etc., wherein the valve seat is provided with a sealing ring, and the small hard core, the large diaphragm and the large hard core are riveted together by screw bolts and arranged on the valve seat; a conical spring is arranged in the large valve cover, and the large valve cover is covered and fixed by stainless steel screw bolts; the small valve cover and the electromagnetic valve are installed, and closed tubes between a large backpressure chamber and a small backpressure chamber are cast in the large valve cover. The utility model has high intensity, and the two backpressure gas chambers are connected in parallel, so no phenomenon of gas leakage exists; a gas pressure flow passage adopts drowned type, which has low pressure and large blowing quantity.
Description
The utility model relates to a kind of special-purpose jetting deashing device that is used for pulsed jet cloth filter in the environmental protection industry.
What at present, the environmental protection problem of domestic and international all trades and professions solved always is not ideal.Present most of industry is all generally selected pulsed jet cloth filter for use, because the pulse valve in the pulsed jet cloth filter is a critical component, and the structure of using now is to adopt the series connection of two back pressure air chambers, perforate on diaphragm, the back pressure air chamber of two diaphragms is not by the direct air feed of gas bag, reduced the pulse characteristic of winding-up like this, little back pressure air chamber gets gas generation interfered with each other from big back pressure air chamber, and the result causes big abrasive disc and little abrasive disc to press tight and leak gas; Adopt plain film formula structure in addition, diaphragm displacement is little, influences the aperture of pulse valve, and air will change three 90 degree bent angles just can enter winding-up pipe, has increased channel resistance, has increased the required pressure of winding-up, has strengthened energy resource consumption like this and has shortened service life of diaphragm.Therefore develop a kind of submerged pulse valve is scientific research task anxious to be solved both at home and abroad always.
The purpose of this utility model be exactly conceive the science novelty in order to provide a kind of, design is aesthetic in appearance, in light weight, simple for process, properties of product are reliable, cheap, intensity is high, submerged is adopted in two back pressure air chamber parallel connections, ne-leakage gas phenomenon, the runner of calming the anger, reduce channel resistance, low pressure, big winding-up amount, diaphragm displacement are big, reduce energy resource consumption, prolong the diaphragm submerged pulse valve in service life.
The purpose of this utility model is achieved in that whole device is made up of valve seat, bolt, little hard core, big diaphragm, big hard core, magnetic valve, little valve gap, volute spring, big valve gap, stainless steel bolt, sealing ring, sealing ring is installed on valve seat, little hard core, big diaphragm, big hard core are installed on the valve seat after being riveted together with bolt, volute spring is placed in the big valve gap, cover big valve gap and be fixed with stainless steel bolt, little valve gap and magnetic valve are installed, in big valve gap, are cast with the cross over pipe of big back pressure chamber and little back pressure chamber.Main points of the present utility model are its version and operation principle.Its operation principle and method of operating are: the back pressure air chamber of two diaphragms is all by the direct air feed of gas bag, i.e. two back pressure air chamber parallel connections, guaranteed the pulse characteristic of winding-up, adopt the submerged structure, the switching face of valve is positioned at gas bag substantially, and air can directly enter the winding-up pipe by gas bag, has reduced channel resistance, reduce the required pressure of winding-up, realized the purpose of low pressure, big winding-up amount.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
With reference to accompanying drawing, whole device is made up of valve seat 1, bolt 2, little hard core 3, big diaphragm 4, big hard core 5, magnetic valve 6, little valve gap 7, volute spring 8, big valve gap 9, stainless steel bolt 10, sealing ring 11, sealing ring 11 is installed on valve seat, little hard core 3, big diaphragm 4, big hard core 5 usefulness bolts 2 are installed on the valve seat 1 after being riveted together, volute spring 8 is placed in the big valve gap 9, covering big valve gap 9 also is fixed with stainless steel bolt 10, little valve gap 7 and magnetic valve 6 are installed, in big valve gap 9, are cast with the cross over pipe of big back pressure chamber and little back pressure chamber.
The submerged pulse valve compared with prior art, have design science novelty, the design aesthetic in appearance, In light weight, simple for process, properties of product are reliable, cheap, intensity is high, two back pressure air chambers Parallel connection, ne-leakage gas phenomenon, the runner of calming the anger adopt submerged, minimizing channel resistance, low pressure, big Winding-up amount, diaphragm displacement be big, reduce energy resource consumption, prolong the advantage such as diaphragm service life, will be extensively Be applied in the environmental protection industry.
