Description
Technical Field
The utility model relates to a heat preservation formula electromagnetic pulse valve belongs to pulse jetting bag collector and uses electromagnetic pulse valve technical field.
Background
The working principle of the electromagnetic pulse valve (double diaphragms) is as follows: the main diaphragm 1 divides the big air cavity of the electromagnetic pulse valve into a first front air chamber 2 and a first rear air chamber 3, the auxiliary diaphragm 4 divides the small air cavity into a second front air chamber 5 and a second rear air chamber 6, and after the electromagnetic pulse valve is connected with the air distribution box (air bag), compressed air enters the first rear air chamber 3 and the second rear air chamber 6 through a first throttling hole 7 and a second throttling hole 8 respectively, and the second air release hole 11 and the first air release hole 12 are blocked. The pressure in the first rear chamber 3 presses the main diaphragm 1 against the output port 9 and the electromagnetic pulse valve is in the "closed" state, as shown in figure 1a.
The armature 10 of the electromagnetic pulse valve is moved by the electric signal of the pulse injection controller, the second vent hole 11 is opened, the second rear air chamber 6 loses pressure rapidly, the auxiliary diaphragm 4 moves backwards, the first vent hole 12 is opened, the first rear air chamber 3 loses pressure rapidly, the pressure of the first front air chamber 2 moves backwards the main diaphragm 1, the compressed gas is injected through the output port 9, and the electromagnetic pulse valve is in an 'open' state, as shown in fig. 1b.
The electric signal of the pulse injection controller disappears, the armature 10 of the electromagnetic pulse valve resets, the second vent hole 11 is blocked, the auxiliary diaphragm 4 moves forwards, the first vent hole 12 is blocked, the pressure of the first rear air chamber 3 rises, the main diaphragm 1 is enabled to be tightly attached to the output port 9, and the electromagnetic pulse valve is in a closed state.
Therefore, when the electromagnetic pilot head armature is driven by an electric signal, the opening or closing state of the pulse valve is determined by the movement of the electromagnetic pilot head armature, and the blowing performance of the pulse valve is determined by the action sensitivity of the armature.
The electromagnetic pulse valve is a generator of the dust cleaning air source of the pulse blowing bag type dust collector, and the electromagnetic pulse valve is controlled by the electric signal output by the pulse blowing controller to blow compressed air to clean the filter bag. The electromagnetic pulse valve is driven by an electric signal to make the pilot armature move. The air release hole is opened, and the pressure difference between two sides of the diaphragm is changed to open or close the pulse valve. The movement of the armature iron is one of the main conditions for realizing the opening and closing of the pulse valve, and the action sensitivity of the armature iron is the guarantee of normal ash removal of the dust remover. However, in cold regions, the armature can not work normally due to condensation and freezing, and in order to be used in the cold regions, the armature (sliding iron core) of the pilot part of the electromagnetic pulse valve can be prevented from being condensed and frozen, so that the electromagnetic pulse valve can not be opened and closed normally. In the prior art, the electromagnetic pilot valve 9 and the pulse valve 23 are separately arranged, a group of electromagnetic pilot valves 29 (installed on the same gas separation tank) of the pulse valves are centrally heated and insulated in the electromagnetic pilot valve controller, and the centrally insulated electromagnetic pilot valves 29 are connected with the corresponding pulse valves 23 by nylon gas pipes (i.e., connecting gas pipes 25), as shown in fig. 2.
As shown in fig. 3, two ends of the connecting air pipe 25 are connected with the electromagnetic pilot valve 29 and the pulse valve 23 through the insertion-type air pipe joint 22, the electromagnetic pilot valve controller casing 27 is wrapped on the outer side of the electromagnetic pilot valve 29, the heating element 28 is further arranged in the electromagnetic pilot valve controller casing 27, the end of the electromagnetic pilot valve 29 is further provided with an electromagnetic pilot valve air vent 26, and the pulse valve 23 is provided with an injection pipe 21 and an air distribution box (air bag) 24.
In order to prevent armature from condensing and freezing, the electromagnetic pilot valve 29 is subjected to centralized heat preservation, a device is added between the original product combining the electromagnetic pilot valve 29 and the pulse valve 23, namely the pulse valve and the electromagnetic pilot valve are separately arranged, so that not only are installation devices and workload increased, the cost is increased, but also the possibility of failure is increased, and more importantly, when the electromagnetic pilot valve 29 and the pulse valve 23 are separately arranged, the electromagnetic pilot valve 29 and the pulse valve 23 must use a connecting air pipe 25, as shown in fig. 3. However, the connecting air pipe 25 enlarges the volume of the rear air chamber on the pulse valve 23, increases the time for the rear air chamber to blow and release compressed air, lags behind the opening and closing of the pulse valve 23, and influences the blowing performance of the pulse valve 23.
