Description
Technical field
The utility model relates to the regulating valve field, especially relates to a kind of high-precision flow control valve.
Background technique
The like product of Chu Shouing in the market, all belong to from Japanese import, cost an arm and a leg, and big for maintenance and repair cost from now on, and inconvenient, for present domestic control circuit incompatibility, flow adjustment range is little, control accuracy is low, and can not get bigger raising on energy saving problem, has increased the cost of enterprise.
Summary of the invention
The purpose of this utility model is the above-mentioned shortcoming at prior art, and a kind of electromagnetic expanding valve is provided.
The technological scheme that realizes the utility model above-mentioned purpose is: electromagnetic expanding valve, valve body is provided with first electromagnetic coil and second electromagnetic coil all over the body, valve body lower portion is connected with valve seat, be provided with a valve pocket that is communicated with in valve body and the valve seat, the top is provided with a positioning seat in the valve pocket, below positioning seat, be connected with a spool, the spool top is connected with an electromagnet, the spool lower end is passed intercommunicating pore and is extended to and be connected with valve port in the valve seat, be connected with outer pipe under the valve port, valve seat one side is provided with inlet tube and links to each other with valve pocket.
Described electromagnetic expanding valve, spool include valve rod and needle, and valve rod adopts the outside thread inner hole structure, is provided with a needle spring in the hole, and the stem bottom riveted joint is connected with a needle.
Described electromagnetic expanding valve, second electromagnetic coil bottom is provided with spring clamp.
Described electromagnetic expanding valve, spool adopt with intercommunicating pore and are threaded.
The utility model has the advantages that: electromagnetic expanding valve can utilize first electromagnetic coil and second electromagnetic coil to produce forward and the counterrotating attraction force makes that the spool rotation is up and down, thereby regulate the size of valve port flow, electromagnetic expanding valve is to close sealing, high-precision flow control valve, be equipped with correspondent control circuits and can realize full-automatic closed loop debugging, it is big to have flow adjustment range, the control accuracy height, governing speed is fast, anti-fluorine point advantage, be mainly used in the control of highly pressurised liquid and gas, be specially adapted to the flow control system of air-conditioning and refrigeration plant, can realize the automatic adjusting of temperature, have energy saving, unloading starts, automatic defrosting, prolong the complete machine characteristics in working life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure, 1 is valve body, and 2 is first electromagnetic coil, and 3 is valve seat,, 4 is valve pocket, 5 is positioning seat, and 6 is spool, and 7 is needle, and 8 is intercommunicating pore, and 9 is valve port, and 10 is outer pipe, 11 is inlet tube, and 12 is the needle spring, and 13 is spring clamp, and 14 is electromagnet, and 15 is valve rod, and 16 is second electromagnetic coil.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
Electromagnetic expanding valve, valve body 1 whole body is provided with first electromagnetic coil 2 and second electromagnetic coil 16, valve body lower portion is connected with valve seat 3, be provided with a valve pocket that is communicated with 4 in valve body 1 and the valve seat 3, can allow spool 6 up and down in valve pocket 4 like this, the top is provided with a positioning seat 5 in the valve pocket 4, make the effect of playing the location when spool rotates to certain position, below positioning seat 5, be connected with a spool 6, spool 6 tops are connected with an electromagnet 14, the effect that can allow spool 6 be subjected to electromagnetic attraction is rotated, spool 6 lower ends are passed intercommunicating pore 8 and are extended in the valve seat 3 and be connected with valve port 9, valve port is connected with outer pipe 10 9 times, and valve seat 3 one sides are provided with inlet tube 11 and link to each other with valve pocket 4.Spool 6 is combined by valve rod 15, needle 7, and valve rod 15 adopts the outside thread inner hole structure, is provided with a needle spring 12 in the hole, and the riveted joint of valve rod 15 bottoms is connected with a needle 7, like this can be so that but needle 7 has certain elasticity do not come off.First electromagnetic coil, 2 energising backs produce and are rotated in the forward attraction force, second electromagnetic coil, 16 energising backs produce the counterrotating attraction force, make that spool forward or counterrotating are up and down, thereby the size of control valve port 9 flows, second electromagnetic coil, 16 bottoms are provided with spring clamp 13, can effectively block valve body, it is not dropped or produce displacement.Spool 6 adopts with intercommunicating pore 8 and is threaded, and can play positioning action like this, can play an effect of supporting spool 6 again.
