Abstract

The utility model discloses a combined solenoid valve, which is suitable for the waste water flow control for the reverse osmosis water treatment. The combined solenoid valve comprises a magnet conduction ring, a spacer sleeve, a solenoid valve plug, a spring of the solenoid valve plug, an electromagnetic coil and a coil fixing rack, wherein a valve piston is arranged between a valve body liquid flowing-in cavity and a valve body liquid flowing-out cavity to be linked with the solenoid valve plug; meanwhile, a throttle valve is arranged between the valve body liquid flowing-in cavity and the valve body liquid flowing-out cavity; the throttle valve comprises a flow guide hole, a through hole and a valve plug, wherein the valve plug is a regulation valve which is arranged between the valve body liquid flowing-in cavity and the valve body liquid flowing-out cavity and is matched with the through hole; and the valve plug is provided with a seal ring. The combined solenoid valve is improved to change the valve plug of the throttle valve in the combined solenoid valve into the regulation valve with a thread; and the valve plug of the throttle valve is connected with the valve body liquid flowing-in cavity and the valve body liquid flowing-out cavity by the through hole; the valve plug is rotated by the thread; the size of the through hole is regulated so as to control the water flow amount; and therefore, the water flow is guaranteed by the combined solenoid valve to be constant and precise. The combined solenoid valve has the advantages of simple structure and strong practicality and is convenient to operate.

Description

Multifunctional electromagnetic valves

Technical field

The utility model relates to a kind of valve, and particularly a kind of multifunctional electromagnetic valves is applicable to the wastewater flow control that reverse osmosis water is handled.

Background technique

Solenoid valve is to utilize its spool to move the valve that flow was opened or blocked in control; And the occasion of regulating loine pressure and flow at needs; For example in reverse osmosis water was handled, it was not enough that solenoid valve is only arranged, in order to reach the purpose of regulating loine pressure and flow; Also need throttle valve and be connected in parallel in the pipeline, so multifunctional electromagnetic valves just occurred.China's utility model patent number is that 200520075268.8 multifunctional electromagnetic valves is throttle valve and electromagnetic valve group lumped together and is used for the current limliting voltage stabilizing; This multifunctional electromagnetic valves comprises magnetic guiding loop, separation sleeve, electromagnetic valve core and spring thereof, electromagnetic coil, coil stationary frame; Between valve body flow turnover die cavity, be provided with valve plug and electromagnetic valve core interlock; Between valve body flow turnover die cavity, be provided with throttle valve simultaneously, throttle valve comprises pod apertures, spool, and spool is a U type hollow tube.This model utility is to utilize the diameter of inner pipe of U type hollow tube self and the size that length is come the controlled water flow amount thereof; But under long-term water impact, U type hollow tube spool is worn and torn, and causes in real work; The effect of regulating the current size is bad; Be that the water flow of at every turn passing through solenoid valve changes simultaneously, make solenoid valve lose the effect of current limliting voltage stabilizing, cause unnecessary loss.

The model utility content

The utility model mainly solves existing multifunctional electromagnetic valves and receives structural limitations technical problems such as accurately controlled water flow is big or small, easy to wear, and a kind of long service life, current control is accurate, the current limliting voltage regulation result is given prominence to multifunctional electromagnetic valves are provided.

The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:

A kind of multifunctional electromagnetic valves; Comprise magnetic guiding loop, separation sleeve, electromagnetic valve core and spring thereof, electromagnetic coil, coil stationary frame, between valve body flow turnover die cavity, be provided with valve plug and electromagnetic valve core interlock, simultaneously; Between valve body flow turnover die cavity, be provided with throttle valve; Throttle valve comprises pod apertures, through hole and spool, it is characterized in that: described through hole is arranged on the valve body, and the connection flow advances die cavity and flow goes out die cavity; Spool is and the leakproof fit modulating valve of valve body liquid, in order to regulate the size of through hole.

Further, described spool is screwed modulating valve, through rotating regulation valve, regulates the size of through hole.

Further, be furnished with seal ring on the described spool, be used for sealed valve body flow turnover die cavity

The utility model is through to the improvement of multifunctional electromagnetic valves, makes the spool of the throttle valve in the multifunctional electromagnetic valves into screwed modulating valve, and through hole connects valve body flow turnover chamber; Utilize screw thread to screw or unscrew modulating valve, regulate the size of through hole, thus the size of controlled water flow amount; Make it guarantee that flow of water constant is with accurate; Simple in structure, easy to operate, practical.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation;

The A-A sectional view of Fig. 2 Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, the technological scheme of the utility model is done further bright specifically.

Of Fig. 1; The specific embodiment of the utility model is a kind of multifunctional electromagnetic valves; Comprise magnetic guiding loop 1, separation sleeve 2, electromagnetic valve core 5 and spring 3 thereof, electromagnetic coil 4, coil stationary frame 6; Between valve body 7 flows turnover die cavity, be provided with valve plug 8 and electromagnetic valve core 5 interlocks, between valve body 7 flows turnover die cavity, be provided with throttle valve 9 simultaneously, throttle valve 9 comprises pod apertures 91, through hole 92 and spool 93.Is furnished with seal ring 10 on the spool 93.

Through hole 92 is arranged on the valve body 7, and the flow that is communicated with valve body 7 is advanced die cavity and gone out die cavity, and promptly current advance die cavity through pod apertures 91 inflow flows, flow into flows through through hole 92 again and go out die cavity; Flow passes in and out between the chamber and the modulating valve that cooperates with through hole 92 spool 93 on the valve body 7 in order to be arranged on, and spool 93 is provided with regulatable screw thread, with valve body 7 liquid close fits, simultaneously, is furnished with seal ring 10 on the spool 93, further guarantees the sealing in flow turnover chamber.Through rotary spool 93, regulate the size of through hole 92, the spool 93 of screwing, then through hole diminishes; Unscrew spool 93, then through hole becomes big.Through the fluid flow that flow turnover chamber in through hole 92 regulation valve bodies 7 is passed through, reach the purpose of controlled water flow size.

Spool 93 must be screwed modulating valve, but does not receive the restriction of present embodiment, as long as modulating valve is involutory with valve body 7, and cooperates the control flow to pass in and out big or small the getting final product of current in chamber with through hole 92, and the diameter of spool 93 also can change according to actual needs.Because the identical material of spool 93 and valve body 7 employings, and directly involutory on the structure, make this multifunctional electromagnetic valves manufacturing, use and change all easily, not only practice thrift cost, also have practicability.

More than the novel a kind of multifunctional electromagnetic valves that provides of this use has been carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
