Description
Technical field
The utility model relates to a kind of electromagnetic valve structure with return-stopping function, specifically refers to, is applied in the water-drainage solenoid valve structure on pipeline of drinking machine.
Background technique
Common drinking machine has the dense water lines of row, and the dense water discharged filters from drinking machine equipment, and the water after filtration can not connect in tap water pipe line again, therefore this part dense water needs to be disposed in sewerage.Because the mounting distance of client's drinking machine often has certain distance with concentrated water discharge mouth, understand when drinking machine discharges dense water because pipeline distance, cause in dense water lines and have pressure, when drinking machine runs the dense water function of row, because water-drainage solenoid valve waterexit end exists backpressure, the dense water capacity easily from the water inlet of water-drainage solenoid valve waterexit end, then through solenoid valve main body from the water outlet of water-drainage solenoid valve feed-water end, thus cause equipment to break down and machine system leaks.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of electromagnetic valve structure with return-stopping function, can enter solenoid valve by anti-sealing in drainage procedure from waterexit end refluence.
The technological scheme that the utility model solves the problem is as follows:
With an electromagnetic valve structure for return-stopping function, comprise solenoid valve main body, described solenoid valve main body comprises feed-water end and waterexit end, and on described waterexit end, cover has waterproof grommet, it is characterized in that:
The outer circumferential face of described waterexit end has been threaded swivel nut working of plastics, chute is provided with in described swivel nut working of plastics, sealing working of plastics is installed in waterexit end, the front end edge circumferencial direction of described sealing working of plastics has flange, the spring being enclosed within sealing working of plastics is installed between described flange and swivel nut working of plastics, the tail end of sealing working of plastics stretches in chute, the side face of the tail end of described swivel nut working of plastics is provided with the end cap of hollow structure, the front end of described end cap is equipped with fast plug-in card, is provided with seal ring between the described sub-front end of fast plug-in card and end cap inwall.
Further, between the flange of described sealing working of plastics and waterexit end, waterstop sealing circle is installed.
As preferably, for being threaded between described end cap with swivel nut working of plastics.
The length that described fast plug-in card puts in end cap is 3/4ths of the sub-total length of fast plug-in card.
Principle of the present utility model is, when not intaking, the flange of sealing working of plastics and the inwall close contact of waterexit end, keep the sealing state of waterexit end; When after water-drainage solenoid valve water inlet, flow to the water jet propulsion sealing working of plastics of waterexit end, spring is compressed, the flange portion of sealing working of plastics and the inwall of waterexit end are separated, the gap that current are formed from the two is passed through, then flow to swivel nut working of plastics and end cap, finally flow out from fast plug-in card; When waterexit end exists directional pressure, water jet propulsion sealing working of plastics, under the elastic force of spring and the acting in conjunction of current, the flange of sealing working of plastics and the inwall of waterexit end fit tightly again, prevent aqueous reflux from entering in device systems.
To sum up, the utility model can, under waterexit end exists the situation of backpressure, effectively prevent aqueous reflux from entering in device systems, avoids causing equipment to break down and machine system leaks, thus decreases the maintenance cost of water machine, extends the working life of machine system.
