Abstract
The utility model relates to a honeycomb-shaped sliding valve plate used for the novel electromagnetic pulse valve using the sliding sheet (plate) to replace the rubber diaphragm as the switch element. The valve plate has a one-piece structure, and a honeycomb-shaped inner cavity, which has two hollow-out ends. An inner hole or a linear bearing, which is slidably cooperated with a hollow shaft on a valve cover, is disposed in the center of the inner cavity. A circular sliding ring is disposed on a side wall, and an end is provided with a plane sealing ring, besides, the other end is provided with a circular throttle hole. Compared with the prior arts, the utility model is made of metal and macromolecular material and has advantages of light weight, material saving, high strength, and good unity.
Description
Technical field
The utility model relates to the electromagnetic impulse valve field, especially relates to the cellular slip valve plate of a kind of employing sliding spool valve (plate) instead of rubber diaphragm as switching element.
Background technique
Electromagnetic impulse valve is the generating means of pulse blowing bag type dust precipitator deashing air-flow.The ash-removal effect of its performance and quality decision pulse blowing bag type dust precipitator.Traditional electromagnetic impulse valve adopts elastomer diaphragm as switching element.Realize the open and close of valve by the distortion that circumnutates of elastomer diaphragm.Because the aperture of rubber membrane plate valve is placed restrictions on, the cracking pressure rate of climb is difficult to improve, heatproof and decay resistance are restricted, Chinese patent ZL200820054769.1 and ZL200920077763.0 etc. disclose a kind of sliding spool valve that adopts metal or macromolecular material to make, and rolling valve plate substitutes the technology of traditional elastomer diaphragm.Sliding spool valve (plate) is divided into former and later two air chambers with the air cavity of electromagnetic pulse valve body, under the control of electrical signal, utilize the pressure difference of two air chambers and the effect of spring, slided in valve block (plate) front and back in the valve body air cavity, realize the opening and closing of electromagnetic impulse valve.Used sliding spool valve (plate) adopts sheet or two cavity tubes assembled, structurally has defective: 1. the requirement of strength height of sheet or cavity tube, up-to-standard rate is low.2. difficulty of processing is big, complex process.3. use the cost of material higher,, require further improvement and improve at the problem of above-mentioned existence.
Summary of the invention
The purpose of this utility model is exactly the cellular slip valve plate that a kind of in light weight, materials province, intensity height, good integrity are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cellular slip valve plate is characterized in that this slip valve plate is an integral structure, and inner chamber is a cellular structure, and top end face and bottom end face are Pierced structure, and the center of valve plate is provided with the hollow shaft sliding connection on a mesopore or linear bearing and the valve gap.
The slip annular groove is set on the described sidewall, is provided with slip ring in the slip annular groove, the top end face is provided with the torus knot discharge orifice, and the end face seal annular groove is set on the bottom end face, is arranged with end face sealing ring in this annular groove.
Compared with prior art, the utility model adopts metal and macromolecular material to make, and compares with the slip valve plate of original employing sheet or two tubular combinations, has advantages such as in light weight, materials province, intensity height, good integrity.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of cellular slip valve plate, its structure are shown in Fig. 1～3, and this cellular slip valve plate 14 is an integral structure, a linear axis is set in the center hole of valve plate holds 1, with the hollow shaft sliding connection on the valve gap 11.The inner chamber of slip valve plate is a cellular structure, top end face and bottom end face are Pierced structure and are provided with honeycombed support muscle 5, slip annular groove 2 is set on the sidewall of valve plate, be provided with slip ring 9 in the slip annular groove 2, the top end face is provided with torus knot discharge orifice 3, end face seal annular groove 4 is set on the bottom end face, is arranged with end face sealing ring 15 in this annular groove.
By the utility model as shown in Figure 4 as sliding spool valve (plate) the formula electromagnetic impulse valve of switching element.Linear bearing 1 on the cellular slip valve plate 14 is slidingly matched with the hollow shaft on the valve gap 11, and air chamber 19 and rear gas chamber 17 before the air cavity of electromagnetic pulse valve body 18 is divided into, elder generation's electrically conducting head 6 is located at the topmost part, set gradually vent hole 7 between elder generation's electrically conducting head 6 and the valve gap 11, guide's valve gap 8, valve block 10, valve block 10 outsides offer annular groove, slip ring 9 is set in the groove, the downside of valve gap 11 is provided with cushion pad 12, formerly under the state of electrically conducting head 6 dead electricity, valve block 10 is blocked rear gas chamber's exhaust port 16, the pressure of rear gas chamber 17 is blocked cellular slip valve plate 14 output terminal 20 of valve, and by end face sealing ring 15 reliable sealings in the end face seal annular groove 4, electromagnetic impulse valve is in closed condition.After electrical signal is connected first electrically conducting head 6, vent hole 7 venting, valve block 10 displacements, the gas of rear gas chamber 17 is discharged by exhaust port 16, rear gas chamber's 17 decompressions, the pressure of preceding air chamber 19 are moved after with cellular slip valve plate 14, leave the output terminal 20 of valve, gas is from output terminal 20 ejections of valve, and electromagnetic impulse valve is in opening state.
The electrical signal of electrically conducting head 6 disappears in the ban, vent hole 7 is closed, valve block 10 resets, block rear gas chamber's exhaust port 16, gas is inflated to rear gas chamber 17 by the torus knot discharge orifice 3 on the cellular slip valve plate 14, and the air pressure of rear gas chamber 17 is raise, under the acting in conjunction of the pressure of rear gas chamber 17 and built-in spring 13, make cellular slip valve plate 14 block the output terminal 20 of valve again, and by end face sealing ring 15 reliable sealings, electromagnetic impulse valve is in closed condition again.
