Abstract

The utility model discloses a solenoid valve, which mainly comprises a valve body, a valve cover equipped on the valve body; a coil bobbin is fixedly mounted on the valve cover, and the coil is arranged on the coil bobbin; springs and a movable core rod are equipped inside of the coil bobbin, and the lower end of the movable core rod is fixed with films which are arranged between the valve body and the valve cover; the film is positioned on the upper part of a valve port, and a regulating rod is movably equipped on the valve body; one end of the regulating rod is contacted with the film. By using the solenoid valve of this structure, users only need to adjust the position of the regulating rod for adjusting the closing state of a main valve, with convenient use.

Description

Solenoid valve

Technical field

The utility model relates to a kind of solenoid valve.

Background technique

Solenoid valve is widely used on the pipelines such as liquids and gases, is used for realizing the automatic on-off to pipeline.The structure of traditional electrical magnet valve mainly comprises: valve body, valve gap is installed on the valve body, on valve gap, be installed with coil rack, coil is installed on the coil rack, be provided with spring and active iron core bar in the coil rack, the lower end of active iron core bar is fixed with diaphragm, and diaphragm is installed between valve body and the valve gap, and diaphragm is positioned at the valve port top; Its working principle is: when coil gets when electric, form magnetic field in the coil active iron core bar is sucked back in the coil rack, diaphragm is just opened valve port, makes main valve form path; Behind coil losing electricity, under the effect of spring, the active iron core bar promotes diaphragm and covers on valve port, main valve is formed open circuit---and be that main valve is closed.When the solenoid valve with said structure is used for some special occasions---as the pipeline of combustion gas or Oil-burning range on the time because cooking stove in use needs to keep in a fire---stay promptly that a bit little fire therefore just can not be with the pipeline Close All so that rekindle cooking stove; And the solenoid valve of above-mentioned conventional construction can not be accomplished this point, usually also need be between the import of solenoid valve and outlet tiny pipeline in parallel, to reach the not purpose of Close All of combustion gas or fuel pipe.The inconvenience of so not only complex structure, and installation has also increased potential leakage point.

Summary of the invention

At the problems referred to above, the utility model will provide a kind of solenoid valve that can regulate the main valve closed condition.

For achieving the above object, the technical solution adopted in the utility model is: described solenoid valve, mainly comprise valve body, valve gap is installed on the valve body, is installed with coil rack on valve gap, and coil is installed on the coil rack, be provided with spring and active iron core bar in the coil rack, the lower end of active iron core bar is fixed with diaphragm, and diaphragm is installed between valve body and the valve gap, and diaphragm is positioned at the valve port top; Also be movably set with adjustable lever on valve body, an end of adjustable lever can contact with diaphragm.

The further technological scheme of the utility model is: the mounting type between adjustable lever and the valve body is: fixed block is installed on valve body, and adjustable lever is installed in the tapped hole on the fixed block by screw thread.

The utility model has the advantages that: use the solenoid valve of described structure, as long as suitably adjust the position of adjustable lever, the closed condition that just can regulate main valve is used very convenient.

Description of drawings

Fig. 1 is the structural representation of the buttoned-up status of solenoid valve described in the utility model;

Fig. 2 is the structural representation of the non-buttoned-up status of solenoid valve described in the utility model.

Mode of execution

Below in conjunction with the drawings and specific embodiments technological scheme described in the utility model and working principle thereof are further described.

As shown in Figure 1, solenoid valve described in the utility model, mainly comprise valve body 8, valve gap 5 is installed on the valve body 8, is installed with coil rack 3 on valve gap 5, and coil 2 is installed on the coil rack 3, be provided with spring 1 and active iron core bar 4 in the coil rack 3, the lower end of active iron core bar 4 is fixed with diaphragm 6, and diaphragm 6 is installed between valve body 8 and the valve gap 5, and diaphragm 6 is positioned at the top of valve port 7; Also be movably set with adjustable lever 9 on valve body 8, an end of adjustable lever 9 can contact with diaphragm 6.In the present embodiment, the mounting type between adjustable lever 9 and the valve body 8 is: fixed block 10 is installed on valve body 8, and adjustable lever 9 is installed in the tapped hole on the fixed block 10 by screw thread.Solenoid valve described in the utility model, the principle that its diaphragm 6 opens and closes valve port 7 is identical with the solenoid valve of conventional construction, repeats no more; Its difference is: when needs are not exclusively closed main valve, as long as adjust adjustable lever 9, as shown in Figure 2, with diaphragm 6 tops from valve port 7, concrete top from distance can determine according to actual needs, like this, just can reach the purpose of incomplete throttle down and pipeline.Otherwise, they are not contacted or just contact but do not push up as long as leave adjustable lever 9 under order diaphragm 6 from valve port 7, just can equally with the solenoid valve of ordinary construction use.

In order further to guarantee safety, also can be on adjustable lever 9 suit seal ring 12, gland nut 11 is pressed on the seal ring 12, gland nut 11 is installed on the fixed block 10 by screw thread.

Claims
