Description
Technical field:
The utility model relates to valve, relates in particular to a kind of colliery anti-explosion electric valve.
Background technique:
According to the provisions of the relevant regulations issued by the State, the place that produces dust in the colliery or during other mining industry production operations all must be provided with automatic sprayer, and the auto spraying watering to be to eliminate dust, ensures that the healthy of operation field personnel and safety in production normally carry out.The valve that relies on electrical signal control is a vitals in the automatic sprayer, and under the control of electrical signal, electric valve is opened automatically, has the water of pressure to spray out the elimination dust from nozzle by electric valve in the pipeline.And when equipment stop operation or people's car when not needing spray sprinkler, under electrical signal control, electric valve will be closed automatically, does not allow press water pass through, thereby causes not spray sprinkler of nozzle.The electric valve of prior art in the industry of colliery, it is a kind of needle value that relies on electromagnetic actuation, this needle value is little because of its latus rectum, and easy reason because of aspects such as clamping stagnation, corrosion, grits causes malfunctioning, does not open in the time of this unlatching, when closing, this closes incessantly, hold the high hydraulic pressure of can't stand about 40 kilograms, the life-span is short, makes whole robot device ineffective, make enterprise suffer massive losses, safety in production also can not get ensureing.
The model utility content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of colliery anti-explosion electric valve is provided, can be because of clamping stagnation.Factor such as corrosion, grit causes malfunctioning.Use left and right sides limiting stopper realization tooth sector to do orderly motion, utilize direct current motor to increase the working principle that shuts down because of its internal current, the control direct current generator is done forward and reverse motion, and the realization ball valve is opened automatically, closed; The utility model can have explosive effect place use, and highly sensitive, it is big to bear pressure, long service life.
The purpose of this utility model is achieved in that a kind of colliery anti-explosion electric valve, include the rotation ball valve, direct current generator, gear drive and explosion-resistant enclosure are formed, rotating ball valve is fixed on the bottom of explosion-resistant enclosure with fixing frame, the valve rod that rotates ball valve upwards stretches in the explosion-resistant enclosure, the end of this valve rod installs a tooth sector, the most last gear engagement of this tooth sector and gear drive reduction gear train, this direct current generator connects the circuit board of electric valve, the first gear of this gear drive reduction gear train is meshed with driving gear on the direct current generator output shaft, on the left side that this tooth sector rotates, the limit on the right-right-hand limit position respectively is fixed with left limit piece and right limit piece, the position of this left limit piece and right limit piece respectively with the unlatching of the rotation ball valve of valve rod control, closed position is corresponding.
Said direct current motor, gear drive reduction gear train, tooth sector, left limit piece, right limit piece and electric valve circuit board all are fixed on the frame, this frame is fixed on the bottom end face of explosion-resistant enclosure, and all is contained within the inner chamber of explosion-resistant enclosure.Described gear drive reduction gear wheel is three grades of cylindrical gears trains.
A kind of colliery described in the utility model is as follows with the positive beneficial effect of anti-explosion electric valve: function of the present utility model is, adopted the spherical rotating valve of direct current motor control, when the needs spray sprinkler, under the control of electrical signal, direct current motor starts, and the running of driven gear reducing gear drives a fan tooth crop rotation direction operation at last, thereby drive the roating sphere opening of valves, press water goes out from nozzles spray by rotating ball valve; When not needing spray sprinkler, under action of electric signals, direct current motor drives tooth sector and turns round in the other direction, thereby the rotation ball valve is closed.
Originally the advantage that is model utility is: big because of rotating stimulating the menstrual flow of ball valve, avoided that the factor effects such as clamping stagnation, corrosion, grit of prior art needle value cause malfunctioning, the life-span short.Originally be another advantage of model utility, be that tooth sector is provided with left limit piece and right limit piece, make tooth sector do orderly motion, after tooth sector had been run into a limiting stopper at the volley, direct current motor shut down because of its inner electric current increases, when electrical signal is controlled the direct current motor action again, direct current motor will drive fan tooth crop rotation reversing motion, make to rotate ball valve and close, thus the utlity model has highly sensitive, the advantage of long service life.The 3rd advantage of the present utility model is to have explosion-resistant enclosure, can have the use of explosive operation place.The 4th advantage of the present utility model is the hydraulic pressure that can bear up to 80kg.
