Abstract
The utility model relates to an electromagnetic pulse valve with a plurality of orifices in a valve body, which comprises the valve body, wherein an output port is arranged in the valve body; a valve cover is arranged on the valve body; an electromagnetic guide head is arranged on the valve cover; a movable iron core is arranged in the electromagnetic guide head; a big air cavity positioned in the valve body and the valve cover is divided into a front air chamber I and a back air chamber I through a membrane; a small air cavity positioned in the valve cover is divided into a front air chamber II and a back air chamber II through a small membrane; and when the electromagnetic pulse valve is closed, compressed air enters into the back air chamber II through an orifice II in the small membrane. The electromagnetic pulse valve is characterized in that at least two orifices I are formed in the valve body, when the valve is closed, the compressed air enters into the back air chamber I through the orifices I. According to the electromagnetic pulse valve, the two or more orifices are formed in the valve body to increase the passage area of the orifices, speed up the speed of building back air chamber pressure, and avoid the situation that a switch of the pulse valve is out of control as the orifices are blocked by dust particles in the compressed air.
Description
Technical field
The utility model relates to a kind of electromagnetic impulse valve, relates in particular to a kind of electromagnetic impulse valve that throttle orifice is set at valve body.
Background technique
Electromagnetic impulse valve is the generating means of pulse blowing bag type dust precipitator deashing air-flow, and it opens and closes, and is to change to realize by the pressure that changes diaphragm two sides, and throttle orifice on valve body or the diaphragm sets up and the pressure of the rear side of diaphragm is by being located at.
As shown in Figure 1, air chamber 1 and rear gas chamber 1 before diaphragm 1 is divided into the atmosphere chamber of electromagnetic impulse valve, air chamber 25 and rear gas chamber 26 before Small diaphragm-piece 4 is divided into little air cavity, when connecting compressed air gas source, pressurized air enters rear gas chamber 1 and rear gas chamber 26 respectively by the throttle orifice 1 on the diaphragm 1 and the throttle orifice 28 on the Small diaphragm-piece 4, because of vent hole 1 and vent hole 2 12 all by shutoff.The pressure of rear gas chamber 1 makes diaphragm 1 be close to delivery outlet 9, and electromagnetic impulse valve is in " closing " state.
As shown in Figure 2, when the electrical signal of pulse jet controller moves electromagnetic pulse valve actuation iron core 10, vent hole 1 is opened, rear gas chamber's 26 rapid decompressions are moved behind the Small diaphragm-piece 4, and vent hole 2 12 is opened, rear gas chamber's one 3 rapid decompressions, move after the pressure of preceding air chamber 1 makes diaphragm 1, pressurized air is by delivery outlet 9 winding-ups, and electromagnetic impulse valve is in " unlatching " state.
The electrical signal of pulse jet controller disappears, and electromagnetic pulse valve actuation iron core 10 resets, vent hole one 11 shutoff, and Small diaphragm-piece 4 reaches, vent hole 2 12 is by shutoff, and rear gas chamber's one 3 pressure raise, and make diaphragm 1 be close to delivery outlet 9, and electromagnetic impulse valve is in " closing " state.
This shows that throttle orifice is the passage of setting up the air-flow of rear gas chamber's pressure, electromagnetic impulse valve is closed.Vent hole is the passage that discharges rear gas chamber's air-flow, makes the electromagnetic pulse opening of valves.Prior art arranges throttle orifice at electromagnetic impulse valve two kinds of modes.A kind of being arranged on the valve body only arranges a throttle orifice.Another kind is arranged on the diaphragm, and one or more throttle orifices can be set.Shortcoming for a throttle orifice that is arranged on valve body is: it is slower that rear gas chamber's pressure is set up speed, and it is corresponding fast to make electromagnetic impulse valve to make.
Summary of the invention
The purpose of this utility model provides a kind of air chamber pressure and sets up speed electromagnetic impulse valve faster.
In order to achieve the above object, the technical solution of the utility model has provided a kind of electromagnetic impulse valve that a plurality of throttle orifices are set at valve body, comprise valve body, in valve body, be provided with delivery outlet, valve gap is located on the valve body, be provided with the electromagnetic pilot head at valve gap, in the electromagnetic pilot head, be provided with moving iron core, the atmosphere chamber that will be positioned at valve body and valve gap by diaphragm is divided into preceding air chamber one and rear gas chamber one, the little air cavity that will be positioned at valve gap by Small diaphragm-piece is divided into preceding air chamber two and rear gas chamber two, when closing, pressurized air enters rear gas chamber two by the throttle orifice two on the Small diaphragm-piece, it is characterized in that: be provided with at least two throttle orifices one at valve body, when closing, pressurized air enters rear gas chamber one one by one by throttle orifice.
When the utility model arranges two or more throttle orifices at valve body, increase the throttle orifice aisle spare, accelerate the speed that rear gas chamber's pressure is set up, and prevent that grit in the pressurized air from stopping up throttle orifice and the sentinel valve switch is out of control.

Embodiment
For the utility model is become apparent, now with preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figures 3 and 4, a kind of electromagnetic impulse valve that a plurality of throttle orifices are set at valve body that the utility model provides, comprise valve body, in valve body, be provided with delivery outlet 9, valve gap is located on the valve body, be provided with the electromagnetic pilot head at valve gap, in the electromagnetic pilot head, be provided with moving iron core 10, the atmosphere chamber that will be positioned at valve body and valve gap by diaphragm 1 is divided into preceding air chamber 1 and rear gas chamber 1, the little air cavity that will be positioned at valve gap by Small diaphragm-piece 4 is divided into preceding air chamber 25 and rear gas chamber 26, is provided with at least two throttle orifices 1 at valve body.
When connecting compressed air gas source, pressurized air enters rear gas chamber 1 and rear gas chamber 26 respectively by the throttle orifice 28 on throttle orifice 1 and the Small diaphragm-piece 4, because of vent hole 1 and vent hole 2 12 all by shutoff.The pressure of rear gas chamber 1 makes diaphragm 1 be close to delivery outlet 9, and electromagnetic impulse valve is in " closing " state.
When the electrical signal of pulse jet controller moves iron core 10, vent hole 1 is opened, rear gas chamber's 26 rapid decompressions, move behind the Small diaphragm-piece 4, vent hole 2 12 is opened, rear gas chamber's one 3 rapid decompressions, and the pressure of preceding air chamber 1 moves after making diaphragm 1, pressurized air is by delivery outlet 9 winding-ups, and electromagnetic impulse valve is in " unlatching " state.
The electrical signal of pulse jet controller disappears, and electromagnetic pulse valve actuation iron core 10 resets, vent hole one 11 shutoff, and Small diaphragm-piece 4 reaches, vent hole 2 12 is by shutoff, and rear gas chamber's one 3 pressure raise, and make diaphragm 1 be close to delivery outlet 9, and electromagnetic impulse valve is in " closing " state.
