Description
Technical field
This utility model relates to test analysis apparatus field, is a kind of nozzle rainfall distribution characteristics test device electromagnetic valve.
Technical background
Nozzle is widely used in the industries such as metallurgy, chemical industry, environmental protection, electronics, weaving, pharmacy, play cooling, dedusting, coat, the effect such as cleaning.The rainfall distribution characteristics of nozzle is one of important quality index of nozzle, the water smoke field of its reflection nozzle ejection water distribution situation in the plane.Method of testing is by how many water yields of unit are top nozzle ejection in measurement certain time weighs whether nozzle rainfall distribution characteristics meets design requirement, its test device has various ways, a large amount of electromagnetic valve need to be used to carry out discharging water and handover measurement for realizing automatization, currently used finished product electromagnetic valve the most all also exists some shortcomings.
The test of nozzle rainfall distribution characteristics has the features such as many, data tired, the test period length of process of measurement point, the most triformed measurement apparatus, and two of which uses electromagnetic valve for draining and measurement switching:
1, measure the water yield in each collector pipe with graduated cylinder, carry out artificial data process.This method measures time length, anthropic factor greatly, and cannot realize automatization, not electromagnetic valve.
2, pressure transducer and drain solenoid valve are installed bottom each collector pipe, measure each pressure sensor data by computer data acquisition system, then be converted into the water yield.This method cost is higher, every difficult consistent, calibration complexity of pressure transducer zero point terminal, and numerous pressure transducer and drain solenoid valve concentrate on bottom of device structure complexity, volume difficulty reduces.
3, each collector pipe connects independent switching solenoid valve, led by valve again or pipeline UNICOM is to a pressure transducer, draining uses independent electromagnetic valve, measure computer-chronograph measurement system and open switching solenoid valve one by one, the collector pipe water yield of correspondence, then draining one by one it is converted into after detection pressure sensor signal.This method automaticity is higher, and cost is relatively low, but device volume is big, connecting leg is many, structure is complicated owing to using independent electromagnetic valve to cause test, and is difficult to reduce unit catchment area, thus affects the segmentation degree of test.
Summary of the invention
The purpose of this utility model is that a kind of volume is little, easy for installation, cost is low, integrate the compound electric magnet valve measuring switching with draining for the test device offer of nozzle water distribution, simplify apparatus structure, reduce manufacturing cost, and precision and the concordance of nozzle water distribution test can be improved, reduce measuring unit area increase way.
For realizing above-mentioned target, this utility model provides following technical scheme:
A kind of nozzle water distribution test device compound electric magnet valve, including: a valve body and multiple spool, spring, solenoid, the plurality of electromagnetic valve moving component of screw composition；Multiple internal thread interface is arranged at described valve body top, can be connected with collector pipe；Valve body lower portion has multiple discharge outlet；The left and right portion of valve body is respectively arranged with a measured hole, can be connected with pressure transducer；Plurality of electromagnetic valve moving component and inner passage on valve body realize multy-way switching measurement when nozzle water distribution is tested and the big function of draining two.
Further, described valve inner has certain passage, valve body upper-part centralized aquaporin to be connected with antero-posterior pathway respectively, and prepass is connected to passage and measured hole with left and right in inside with the gap between valve body by switching spool；Rear passage is connected with drainage channel and discharge outlet in inside with the gap of valve body by drain plug.With solenoid energising, power-off controls the gap between spool and valve body has, nothing.
Further, the prepass being connected with measured hole is less than the rear passage being connected with discharge outlet.
Further, the number of collector pipe way can be realized by the increase and decrease of the increase and decrease of described body length and solenoid movement parts.

Accompanying drawing marks: 1, valve body；2, switching spool；3, switching solenoid；4, drain plug；5, draining solenoid；6, internal thread interface；7, collecting channel；8, rear passage；9, drainage channel；10, discharge outlet；11, prepass；12, left and right is to passage；13, measured hole；14, spring；15, screw.
Detailed description of the invention
Referring to the drawings embodiment of the present utility model is described further.
Reference Fig. 1, this utility model relates to a kind of nozzle water distribution test device compound electric magnet valve, valve body 1 and some groups of switching spools 2, switching solenoid 3, drain plug 4, draining solenoid 5, spring 14, screws 15 form compound electric magnet valve entirety.Switching solenoid 3, draining solenoid 5 power-off before measuring, switches spool 2, drain plug 4 under action from the spring 14, makes switching spool 2, drain plug 4 and valve body gapless, and collecting channel 7 is the most obstructed with discharge outlet 10 and measured hole 13.Nozzle spray, the collector pipe water receiving being connected with internal thread interface 6, after certain time, it is energized to a road switching solenoid 4, the high stress of the water connect passes through prepass 11, switching spool 2 and valve body gap, left and right is to passage 12, measured hole 13 is delivered to the pressure transducer being attached thereto, gathered data reduction by computer measurement system and become the water yield, complete a road measure of water, hereafter this road switching solenoid 4 power-off, it is energized to again next road switching solenoid 4, the high stress of this road water is by transmission, gather, conversion, it is switched to next drive test amount again, until the water yield in all collector pipes is measured；Being energized to the draining solenoid 5 of all ways, the water in collector pipe, by drain plug 4, drain plug 4 and valve body gap, is discharged from discharge outlet 10, completes the test of primary nozzle water distribution.
For reducing bubble and the impact on certainty of measurement of the zero-bit water level, the prepass 11 for pressure transmission is less than the rear passage 8 for draining.
Actually used proof, the compound electric magnet valve that the present embodiment makes is used in nozzle water distribution test device, making test apparatus structure is simple, volume reduces, unit are attenuates, way increase, certainty of measurement and concordance preferable, and low cost, easily install, easily debug.
