Abstract

The utility model discloses a magnetic valve comprising a valve body, a valve cover, a diaphragm, an adjustment rod and an electromagnetic valve body, which is characterized in that a valve body made of non-metal materials is provided with screw holes; an opened water inlet port, a closed water inlet port and a balanced sealing port are embedded with the insertion components of metal components; an iron core in the inner cavity of the electromagnetic valve body is designed into a conical surface. Compared with the existing non-metal electromagnetic valves, the utility model has the advantages of good rigidity and long service life; compared with the existing copper alloy electromagnetic valves, the production cost is reduced.

Description

Electromagnetic valve

The utility model relates to valving, particularly a kind of electromagnetic valve with electric control boiling water and Guan Shui.

The water valve of existing commercially available charged magnet valve door, it comprises: assemblies such as valve body, valve gap, barrier film, adjustable lever and electromagnetic valve body.External product is generally the ABS duroplasts and makes for nonmetal entirely, and is easy to wear, is not durable.Home products is that Cuprum alloy is made, and the cost height, costs an arm and a leg.

The purpose of this utility model provides a kind of with electric control boiling water and Guan Shui, with the electromagnetic valve of metal and nonmetallic phase combination.And easy to use, cost is low, and durable.

For reaching above-mentioned purpose, the utility model is to realize that by the valve of following structure this valve comprises: valve body, valve gap, barrier film, adjustable lever and electromagnetic valve body.Described valve gap and barrier film are screwed on valve body, and its barrier film separates the entery and delivery port on the axis of the valve body that coexists.On the vertex of a cone of valve gap cylindrical slideway is arranged, by its screw thread secured adjusted bar, at the next door of adjustable lever Motionless electromagnetic valve body.Screw hole on the described valve body all studs with threaded metal backing member at internal layer; Between the water intake of valve body and water outlet, a partition is arranged, on flat mouthful of cutting off, be inlaid with circular metal backing member equally.Under the effect of adjustable lever, barrier film contacts with the inserter face and reaches sealing purpose also; On the valve body under the described electromagnetic valve, have one perpendicular to water outlet and with the hole that communicates, in the hole, also be inlaid with one for splitting the pipe of shape, as the balanced seal mouth, the gasket seal that links to each other with the solenoid valve iron core contacts, and opening, opening of it is to control by the upper and lower of electromagnetic core.Thus, reach purpose by electric control boiling water, Guan Shui.

Core design becomes the conical surface in the described electromagnetic valve body, increases the suction surface of contact, and is therefore, more steady.

The utility model electromagnetic valve is compared with the electromagnetic valve of prior art, has following advantage: compare with external complete nonmetal similar valve, be inlaid with the metal backing member on its critical component, and wear-resisting, prolonged working life; Compare with homemade full Cuprum alloy valve, reduce production costs, be convenient to promote, use.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the general structure schematic representation of electromagnetic valve.

Fig. 2 is three kinds of shape schematic representation of a, b, c of damascene part among Fig. 1.

Fig. 3 is a core structure schematic representation in the electromagnetic valve body.

Fig. 1 and Fig. 2 show the overall mode of embodiment of the present utility model.Be the valve body 1 of nonmetallic material, have the water intake 12 that is interconnected, water outlet 13; Barrier film 3 places between valve body 1 and the valve gap 2, by screw 17 three is fixed together, barrier film 3 is also connected with adjustable lever 8 by nut 16, adjustable lever 8 is fixed in the cylindrical guide of the vertex of a cone of valve gap 2, have the screw thread can regulate to put in the length of valve body 1,

damascene part

11,14,15 is embedded in respectively in screw hole 9, open and close water intake 7 and the balanced seal mouth 6 of valve body 1.Electromagnetic valve body 4 be screwed in valve gap 2 in the tapped hole of valve body 1 stable equilibrium sealed mouth 6, gasket seal 10 is fixed on the lower end of iron core 5, together puts into the inner chamber of electromagnetic valve body 4 with iron core 5, is subjected to its upper and lower moving of electromagnetic valve body 4 controls.

Fig. 2 (a) illustrates the shape and structure of the damascene part 11 of screw hole 9 internal layers, and purpose is to improve the defective of the easy slide fastener of nonmetal tapped hole, increases the service life; Fig. 2 (b) is the profile and the structural drawing of open and close intake-outlet damascene part 14, and reason is that metalwork easily reaches the surface finishment of sealing plane, is beneficial to barrier film 3 to cooperate, and makes better tightness; Fig. 2 (c) is the shape and structure figure of the damascene part 15 of balanced seal mouth 6, and its purpose is to improve the flatness and the soundness of the sealing edge of a knife, increases the number of times of opening, opening, and increases the service life.Three kinds of damascene parts shown in this Fig. 2, be generally be difficult for getting rusty, good, the low-cost metal of intensity and alloy, as copper, stainless steel and so on.

Fig. 3 is the cone structure schematic representation of iron core, is designed to cone structure, its purpose be than the area of the contact on plane greatly, more steady.
