Technical field
The present invention relates to the spray valve that multichannel is provided with, in a kind of equipment that is applied in beneficiate material of more specifically saying so, the multichannel spray valve that the variation particle is accurately rejected fast with the air-flow that sprays.
Technical background
At present, both at home and abroad in the material sorting apparatus, air reservoir, solenoid valve, nozzle several sections be all as independent device, between adopt tracheae to be connected with joint flexible, constitute a structural type of overlapping separated.In order to improve the working efficiency of material sorting apparatus, an equipment need be provided with many this kind of group separated structure forms, this structural type is reducing equipment volume, simplified structure, is reducing cost, and reduce gas and decrease, shorten the response time, all be greatly limited thereby improve aspects such as sorting precision, raising functional reliability.
Along with the continuous development of modern science and technology, purity requirement civilian and industrial material improves constantly.As the material sorting apparatus, in to the sorting device miniaturization, the requirement that reduces air-flow loss in the gas circuit transmission course is more and more higher, and obviously, the separated structure setting can not be satisfied specific requirement.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology deficiency, a kind of integration multi-port spraying valve is provided, adopt integrated setting with the physical dimension of reduction equipment, reduce cost; Reduce gas by integrated setting simultaneously and decrease, to shorten the response time better, raising sorts precision, improves reliability.
Technical solution problem of the present invention adopts following technological scheme.
The structural feature of integration multi-port spraying valve of the present invention be with side by side, symmetrically arranged a pair of high speed electromagnetic pneumatic valve is one group of valve, there is n group valve arranged side by side, constitute the pneumatic valve array of 2 * n, above the pneumatic valve array, with the cylinder is substrate, collector plate is set, and is to walk abreast into row to be arranged in recessed road in the collector plate inwall with air-flow path that each pneumatic valve air outlet is communicated with, the top port in each recessed road respectively with corresponding position on, be arranged on the spout connection in the nozzle plate.
The structural feature of integration multi-port spraying valve of the present invention also is:
Corresponding to symmetrically arranged two-way pneumatic valve, be " eight " word front side collector plate and rear side collector plate are set, be on the collector plate on the corresponding side with air-flow path branch that the pneumatic valve air gate of two-way is communicated with respectively.
Cylinder is polygonal external form and inner chamber is set, and the air outlet is distributed in its both sides, and the shared gas-entered passageway in each air outlet is provided with two end caps at the two ends of cylinder, and rapid pipe joint is set constitutes suction port.
Each air-flow path that is arranged on front side collector plate and the rear side collector plate is staggered one by one on cross section place.
The spray angle of spout is adjustable arbitrarily, and the spout of nozzle plate comprises round mouth and flat mouth.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention will be sprayed the integrated setting of valve, dwindle physical dimension, the reduction equipment cost of equipment effectively.
2, the present invention is provided with the rigidity air-flow path for the spray valve, and the air-flow stroke is short, gas circuit is smooth and easy, can reduce gas greatly and decrease, can shorten the response time better, raising sorts precision, improves reliability, simultaneously, gas circuit structure is solid and reliable, can greatly reduce the gas circuit amount of maintenance.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, with side by side, symmetrically arranged a pair of high speed electromagnetic pneumatic valve 1 is one group of valve, has n group valve arranged side by side, constitutes the pneumatic valve array of 2 * n.
Fig. 2, shown in Figure 3 above the pneumatic valve array, is a substrate with cylinder 3, and collector plate is set, and comprises front side collector plate 4 and rear side collector plate 7.
Shown in Figure 4, be to walk abreast into row to be arranged in recessed road 13 in the collector plate inwall with air-flow path that each pneumatic valve air outlet 2 is communicated with, the top port in each recessed road respectively with corresponding position on, the spout 6 that is arranged in the nozzle plate 5 is communicated with.
Fig. 2, shown in Figure 3 corresponding to symmetrically arranged two-way pneumatic valve, is " eight " word front side collector plate 4 and rear side collector plate 7 is set, and is on the collector plate on the corresponding side with air-flow path branch that the pneumatic valve air gate of two-way is communicated with respectively.
In concrete the enforcement, the corresponding structure setting also comprises:
Cylinder 3 is a metal construction, adopts polygonal external form and inner chamber setting, and the air outlet is distributed in its both sides, and the shared gas-entered passageway 9 in each air outlet is provided with two end caps 8 at the two ends of cylinder 3, and rapid pipe joint 10 formation suction ports are set.Spray valve 1 is fixedly installed on the cylinder 3 by Cock screw 11 and pad 12, the keying of control spout,
The two-side current collecting plate is a non-metallic member, recessed road 13 correspondences as air-flow path in the collector plate inwall are connected between air outlet 2 and the spout 6, for the ease of arranging of each spout 6, each air-flow path that is arranged on front side collector plate 4 and the rear side collector plate 7 is staggered one by one on cross section place.
The spray angle of spout 6 can be provided with as required, in order to adapt to different materials, can comprise round mouth or flat mouth by changing nozzle plate 5 to obtain different spout forms.
In the working procedure, pressed gas enters cylinder 3 by rapid pipe joint 10, by the keying of spray valve control gas circuit.When normal material blanking, the high speed electromagnetic pneumatic valve cuts out, and pressed gas rests in the cylinder, and at this moment, device is in closed condition, the normal discharging of material; In case detect the signal that the variation granule materials passes through, the drive circuit output signal, the high speed electromagnetic pneumatic valve is opened, pressed gas sprays air-flow directive variation granule materials by collector plate rapidly in the spout of correspondence, along with blackout, the high speed electromagnetic pneumatic valve cuts out, and material recovers normal discharging.
