Description
(1) technical field
The utility model relates to a kind of coal separation, the ore dressing ecp cover plate air-valve with jigging machine, particularly be the Zero-backpressure electronically-controlled pneumatic single cover plate air-valve of jigging machine modular, belong to the jigging machine parts.
(2) background technology
On the jigging machine that coal separation and ore dressing are used, the ecp air-valve is to be used to control jigging machine work with low-pressure air (blast is 0.02MPa--0.06MPa), makes the critical component of jigging machine generation work fluctuating flow.At present domestic what generally adopt is the ecp air-valve, the ecp list cover plate valve of the Ba Dake type jigging machine of producing as German KIID company, the box ecp cover plate of the x series jigging machine valve that coal separation designing institute in table mountain produces.Its formation comprises solenoid directional control valve, bellows, be located at cylinder (cylinder piston rod stretches in the bellows) on the bellows, be positioned at work cover plate, the air inlet that is located at bellows, exhaust outlet and rubber valve seat that bellows are fixed on piston-rod lower end.Several these valves are made in a length are about in 5m, 1m, the big bellows more than the 0.7m, not only bulky, the manufacturing cost height.And, when the work cover plate was closed exhaust outlet, bellows were only connected with air inlet, are full of the compressed air of 0.02MPa--0.06MPa in the bellows, before giving the Intake Cover plate valve unlatching of jigging machine air feed, back pressure is arranged on the cover plate, when cylinder is opened cover plate by piston rod, at first this back-pressure balance is fallen, this has just wasted the part merit, the cover plate breakdown action lags behind the electric-control system instruction, and is unfavorable to the service behaviour of jigging machine, damages the seal gasket of air inlet simultaneously easily.Cover plate is opened moment, and back pressure disappears and increases the cylinder piston motion inertia force, increases the piston deceleration burden, occurs hitting the cylinder phenomenon easily; Otherwise when air inlet operating valve cover plate was closed, back pressure occurred, and added the dynamics of large cover bump air inlet, can shorten the service life of related components.
In order to eliminate the back pressure on the cover plate, the ecp jig piston valve has been produced in the design of CHINESE COAL Ke Yuan Tangshan branch, the valve pocket that the work cover plate of cover plate valve is changed into the hollow cylinder spool of vertical installation, is slidingly matched with spool, spool is driven by cylinder piston rod and moves up and down, when spool circle mouth staggers with valve pocket circle mouth or overlaps, promptly realize air intake and air draft.Though the ecp jig piston valve has overcome the shortcoming that there is back pressure in the cover plate valve, because spool slides up and down in valve pocket, form fretting wear and gap between spool and the valve pocket is increased and cause and leak out, the jigging machine service behaviour is reduced.
(3) utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide that a kind of jigging machine modular does not have back pressure, volume is little, few, easy to maintenance, the no back pressure of parts, flexible, high, the long service life of reliability of switching, can according to jigging machine air chamber number what, neatly several these valves are combined into an integral body, the ecp list cover plate air-valve of the work low-pressure air of control jigging machine.
The purpose of this utility model is achieved in that it comprises the air-valve housing, open the installing hole on the air-valve case panel, be connected in the installing hole cover plate that covers installing hole on the air-valve case panel, be installed in the cylinder on the installing hole cover plate, place the plug that closes in the cylinder, one end with close the plug other end that links and stretch into piston rod in the air-valve housing by hole on the installing hole cover plate and installing hole, the work cover plate that in the air-valve housing, links with piston rod, close the solenoid directional control valve that the plug two ends are connected respectively with in the cylinder by two airducts that are flexible coupling, be connected to the compressed air hose on the solenoid directional control valve and in the air-valve housing, also have air inlet with work cover plate corresponding position, in housing, be connected to the work cover plate valve seat corresponding on the air inlet with the cover plate of working, the place is connected to air inlet pipe at housing external admission mouth, on housing, have the gas outlet, be connected to the escape pipe at place, gas outlet.
Compared with the prior art, advantage of the present utility model:
1. do not have back pressure when air-valve work cover plate is opened, and the amount of parts of using is few, reliability improves, and has prolonged service life.
2. the instruction of the switching of air-valve work cover plate and electric-control system is not leaked out after closing synchronously, has guaranteed jigging machine stable work in work, reliable, is in optimum state.
(4) description of drawings
Accompanying drawing is looked cross-sectional schematic for the utility model master.
(5) specific embodiment
Be described further below in conjunction with accompanying drawing, but be not limited only to this.
Referring to accompanying drawing, one of implementation of the present utility model comprises air-valve housing 10, open the installing hole 13 on air-valve housing 10 panels, be connected in the installing hole cover plate 11 that covers installing hole 13 on air-valve housing 10 panels, be installed in the cylinder 5 on the installing hole cover plate 11, place closing in the cylinder 5 to fill in 14, one end with close plug 14 other end that links and stretch into piston rod 6 in the air-valve housing 10 by hole on the installing hole cover plate 11 and installing hole 13, the work cover plate 7 that in air-valve housing 10, links with piston rod 6, by the airduct 3 that is flexible coupling, 4 close the solenoid directional control valve 2 that plug 14 two ends are connected respectively with in the cylinder 5, be connected to the compressed air hose 1 on the solenoid directional control valve 2 and in air-valve housing 10, also have air inlet 15 with work cover plate 7 corresponding positions, in housing 10, be connected to the work cover plate valve seat 8 corresponding on the air inlet 15 with the cover plate 7 of working, 15 places are connected to air inlet pipe 9 at housing 10 external admission mouths, on housing 10, have gas outlet 16, be connected to the escape pipe 12 at 16 places, gas outlet.
Operation principle of the present utility model is: when solenoid directional control valve 2 for normality (must not) time, compressed air by compressed air hose 1 through solenoid directional control valve 2, the airduct 3 that is flexible coupling enters cylinder 5 upper end air cavitys, piston rod 6 is descending, drive work cover plate 7 is descending, pushes down work cover plate valve seat 8, seals inlet gas, at this moment, the jigging machine work low-pressure air that comes from outside air supply pipe is blocked.When solenoid directional control valve 2 is worked (getting), compressed air enters the lower end air cavity of cylinder 5 through the airduct 4 that is flexible coupling, piston rod 6 is up, the 7 up unlatchings of drive work cover plate, the jigging machine work low-pressure air of outside air supply pipe 9 enters in the air-valve housing 10 through work cover plate valve seat 8, the escape pipe 12 that connects outside the gas outlet enters the jigging machine air chamber again, thereby has realized the no back pressure of jigging machine work low-pressure air is opened and blocking-up.Its characteristics are: when work cover plate 7 is sealed work cover plate valve seat 8 and stopped air feed, do not have compressed air in the air-valve housing 10, do not bear back pressure on the work cover plate 7.
