Abstract
The utility model relates to a double-flux direct-action solenoid valve comprising a valve body which is equipped with a liquid inlet passage and a liquid outlet passage, wherein the liquid inlet passage includes two paths, the first liquid inlet passage is directly communicated with the liquid outlet passage, and a solenoid valve is arranged at the joint of the second liquid inlet passage and the liquid outlet passage. The utility model can realize two different flux of medium and guarantee efficiency and precision, and further, the utility model is simple and reliable in structure, saves manufacture cost ultimately, and has excellent economic application value.
Description
Technical field
The utility model relates to a kind of solenoid valve that use in coal analysis instrument field that is used for.
Background technology
In constant volume type calorimeter product, in need injecting the water of a constant volume among the bucket, guaranteeing normally carrying out of experiment, and utilize water level probe quantitatively in bucket water be exactly wherein a kind of mode.In the prior art, utilize a two-position two-way solenoid valve and an other throttling valve to realize the structure more complicated.
The utility model content
At the problem that prior art exists, it is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and can satisfy the requirement of precision, can improve the double fluid amount direct-acting electromagnetic valve of speed again.
The technical scheme in the invention for solving the technical problem is: a kind of double fluid amount direct-acting electromagnetic valve, it comprises valve body, on described valve body, be provided with feed pathway and liquid outlet channel, described feed pathway is a two-way, wherein first via feed pathway directly is communicated with described liquid outlet channel, the second tunnel feed pathway is provided with double-flow-rate electromagnetic valve with the place of connection of liquid outlet channel, and the second tunnel feed pathway is communicated with liquid outlet channel when this double-flow-rate electromagnetic valve energising.
Described double fluid amount direct-acting electromagnetic valve, described solenoid valve is the closed type solenoid valve.
Described double fluid amount direct-acting electromagnetic valve, described solenoid valve is a normal-open electromagnetic valve.
Described double fluid amount direct-acting electromagnetic valve, described first via feed pathway are communicated with the place with described liquid outlet channel bore is communicated with the bore at place with described liquid outlet channel less than described the second tunnel feed pathway.
Described double fluid amount direct-acting electromagnetic valve, described double-flow-rate electromagnetic valve comprises terminal box, coil, valve gap, described valve gap is arranged under the described coil, described valve gap is arranged on the described valve body, and seal by O-ring seal with valve body, described coil is connected with terminal box, is provided with static iron core, spring and moving iron core in described coil from top to bottom, described moving iron core is located in the described valve gap, and the lower end of moving iron core is against and the be communicated with place of the second tunnel feed pathway with liquid outlet channel.
Double fluid amount direct-acting electromagnetic valve of the present utility model, when solenoid valve is closed type, at the state that does not have energising, second feed pathway is in closed condition, medium flows to liquid outlet channel through first feed pathway, fix at system pressure one, the medium of this moment depends on the first feed pathway cross-sectional sizes through the flow of solenoid valve, and when solenoid valve is switched on, medium flows to liquid outlet channel from first feed pathway and second feed pathway simultaneously, and the flow of medium depends on the size of first feed pathway and the second feed pathway connection place cross section sum; And solenoid valve be open type in contrast.When we used, water inlet that can the big flow of first heavy caliber, and after water is injected into appropriate height just can utilize this method water inlet loop of automaticallying switch, and switches to small-bore water inlet, so both can satisfy accuracy requirement, and the requirement of the speed of having carried is arranged.
