Description
Technical Field
The utility model belongs to the pulse valve field, concretely relates to electromagnetic pulse valve that can manually open and close.
Background
The pulse valve is a special valve for bag type dust collector, and is firstly a diaphragm valve, and is generally called as an electromagnetic pulse valve because the actuating mechanism is of a solenoid pilot driving type. The pulse valve is divided into a submerged type, a right-angle flange type, a straight-through type and a right-angle type with a nut according to the structure. The right-angle pulse valve with the nut is convenient to install, and the sealing ring is screwed and compressed by the nut to seal the connecting pipeline, so that the right-angle pulse valve is widely applied to the pulse bag type dust collector.
Fig. 3 is a schematic structural view of a conventional electromagnetic pulse valve.
As shown in fig. 2, the conventional electromagnetic pulse valve mainly includes a pilot tube assembly 1', a coil assembly 2', a small valve cover 3', a small spring 4', a small diaphragm assembly 5', a large valve cover 6', a large spring 7', a large diaphragm assembly 8', and a valve body 9 '. The pilot tube assembly 1 'is connected to the small valve cover 3' through a screw, the coil assembly 2 'is installed on the pilot tube assembly 1' through a snap spring, the small valve cover 3 'and the small diaphragm assembly 5' are connected to the large valve cover 6 'through screws, the small spring 4' is arranged between the inner wall of the small valve cover 3 'and the small diaphragm assembly 5', the large valve cover 6 'and the large diaphragm assembly 8' are connected to the valve body 9 'through screws, and the large spring 7' is arranged between the inner wall of the large valve cover 6 'and the large diaphragm assembly 8'.
The small diaphragm assembly 5 'and the large diaphragm assembly 8' are utilized to balance pressure to form sealing, compressed gas can reach cavities above the diaphragm assemblies through the throttling holes, pressure difference is caused due to the existence of pressure receiving area difference, the sealing surface of the small diaphragm assembly 5 'is tightly pressed on the sealing seat inside the large valve cover 6', and the sealing surface of the large diaphragm assembly 8 'is tightly pressed on the sealing seat inside the valve body 9' to form sealing.
When the electromagnetic pulse valve needs to be opened, a winding coil of the coil assembly 2' is electrified to generate magnetic field force through an electric signal of the pulse control instrument, the magnetic force overcomes the gas pressure, the spring force and the dead weight which are borne by a movable iron core of the pilot tube assembly 1' to suck the movable iron core, the small membrane assembly 5' moves upwards, at the moment, the vent hole in the large valve cover 6' is communicated with the rear air chamber above the large membrane assembly 8', the gas in the rear air chamber is rapidly discharged, because the gas supplementing speed of the throttling hole in the large membrane assembly 8' is lower than the gas releasing speed of the vent hole, the rear air chamber is rapidly decompressed, the large membrane assembly 8' is pushed upwards by the air pressure in the gas supply bag, the channel at the inner sealing seat of the valve body 9' is opened, the electromagnetic pulse valve is also opened, and the compressed gas in the gas supply bag can be sprayed out from the outlet end of the valve body 9', so as to form instant spraying.
When the electromagnetic pulse valve needs to be closed, the electric signal of the pulse control instrument enables the coil winding of the coil assembly 2 'to lose power, the magnetic field force disappears, the movable iron core of the pilot tube assembly 1' resets under the action of the small spring 4', the small diaphragm assembly 5' also resets and cuts off the communication between the air vent and the rear air chamber, at the moment, compressed air in the air supply bag enters the rear air chamber through the throttling hole in the large diaphragm assembly 8', the pressure of the rear air chamber recovers, the large diaphragm assembly 8' resets under the action of the large spring 7', a channel at the sealing seat in the valve body 9' is closed, and the electromagnetic pulse valve is also closed.
Because the electromagnetic pulse valve is opened and closed by the magnetic field force generated after the coil assembly 2' is electrified, when a maintainer overhauls and maintains on site, if the electric signal cycle period of the pulse controller does not damage the electromagnetic pulse valve to be checked or the pulse controller, the electromagnetic pulse valve cannot be opened and closed, and the maintainer cannot judge the site condition to maintain.
