Abstract
The utility model relates to a incubator relates to a circuit board machine table device, the is in machine table body a side is provided with a head cover, machine table body in corresponding relates to a circuit board machine table device, the is in machine table body a side is provided with a head cover, machine table body in corresponding relates to a circuit board machine table device pressure device pressure stable moreover pressure effect, cost, maintenance use also convenient.
Description
The utility model relates to incubation equipment, particularly the spraying pressue device of hatch machine.
The spraying pressue device of existing incubation equipment comprises water pump 2, pressurized tank 3, pressure switch 4 and relevant pipeline valve as shown in Figure 1, and water pump is water suction pressurized tank 3 from pond 1, reach certain pressure after water pump stop.Under the pressure of air, water enters sprayer unit 5 through pressure valve 4 in jar in pressurized tank, carries out spraying humidification in the hatch machine casing.When the jar internal pressure was lower than certain value, the pressure switch feedback signal of telecommunication was opened water pump, pressurizes to pressurized tank again.The shortcoming of this pressue device is, because pressurized tank internal pressure instability and pressure are on the low side, so atomizing effect is bad, and because the tonifying Qi that will often discharge water, so safeguard that use is relatively complicated, manufacturing cost is also than higher.
The purpose of this utility model provides a kind of new spraying pressue device, and this device has stable and higher hydraulic pressure power, safeguards to use simple and manufacturing cost is lower.
The purpose of this utility model is achieved through the following technical solutions: a kind of spraying pressue device of hatch machine, it is characterized in that by two double-acting cylinders, solenoid directional control valve, stroke signalling generator and collision block, check valve and air compressor constitute, the piston rod of two above-mentioned double-acting cylinders links together by collision block, be installed near the two-end-point of piston rod collision block motion with the stroke signalling generator of this collision block coupling, and be connected with solenoid directional control valve by circuit, the Air Compressor output channel is connected with the piston both sides of a double-acting cylinder by solenoid directional control valve, and the pipeline of drawing from the piston both sides of another cylinder is connected with pond and sprayer unit respectively by two pairs of opposite check valves of direction.
The operation principle of this device is, use compressed air as power, effect by solenoid directional control valve and stroke signalling generator and collision block, promote the piston move left and right of two-way cylinder, because the piston rod of this cylinder is connected by collision block with the piston rod of another cylinder, the piston of another cylinder is also with synchronous move left and right, when piston when a direction moves, water will be by a side that is inhaled into cylinder in the pond by a check valve, when piston when another direction moves, this check valve is in closed condition, and water will enter sprayer unit by another check valve.Because check valve is two groups, so no matter piston to which direction moves, water all will enter sprayer unit equably.
The utility model has the advantages that: one, since the pressure of air compressor in cylinder be uniformly and be higher than water-aspirator pressure, so this device can provide stable and higher hydraulic pressure power.Thereby improve spray effect, the 2nd, owing to cancelled the pressurized tank of prior art, do not need the tonifying Qi that discharges water, safeguard that use is all easier.
Description of drawings:
Fig. 1 is existing hatch machine spraying pressue device structural representation.
Fig. 2 is the utility model principle and structural representation.
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
The said spraying pressue device of present embodiment comprises air compressor 6, two-way cylinder 8 and 10, solenoid directional control valve 7, stroke signalling generator 11, collision block 9, check valve 12, the piston both sides of two-way cylinder 8 are connected by the air output channel of solenoid directional control valve 7 and air compressor 6, two-way cylinder 8 is connected by collision block 9 with 9 piston rod, two stroke signalling generators 11 are installed near two end points of collision block 9 side-to-side movements, the installation site should guarantee just to run into stroke signalling generator 11 when piston moves to the left and right sides endface position of cylinder, makes solenoid directional control valve 7 commutations so that send signal.In the two-way cylinder 8 compressed air is arranged, in the two-way cylinder 10 water is arranged then, also can be described as water vat, the piston left and right sides of this cylinder 10, there is pipeline to communicate with two groups of check valves 12 respectively, the other end of two check valves of first group communicates with the pond, and second group of check valve and first group are oppositely installed, and its other end is connected with sprayer unit.When the piston side-to-side movement of cylinder 8, the piston of cylinder 10 is side-to-side movement synchronously also, with the water at water source suck cylinder 10 not cracked ends check valve 12 flow into sprayer units.The cylinder body of the double-acting cylinder that present embodiment uses is of a size of Φ * L=50 * 140 (mm), and solenoid directional control valve nominal voltage 4V, stroke signalling generator adopt LX-028 type travel switch.
