Abstract

The utility model provides a magnetic valve which belongs to the field of valves, and comprises a valve body; an isolation cover is fixed on the valve body; a protective cover is arranged on the isolation cover; a valve rod is sleeved in the isolation cover; a magnetic column is fixed on the upper end of the valve rod, and the lower end of the valve rod is connected on a valve seat; a membrane is arranged below the valve seat; the edge of the membrane is fixed between the valve body and the isolation cover; the lower part of a pressure rod with the upper part exposed outside the protective cover is provided with a magnetic ring; and the lower surface of the inner side of the isolation cover is a conical surface. Because the lower surface of the inner side of the isolation cover is the conical surface, the magnetic valve improves the up-and-down moving scope of the valve rod, so that the magnetic valve not only can be used for controlling natural gas and liquefied gas pipelines, but also can be used for controlling fuel pipelines, and has wide scope of application.

Description

A kind of magnetic valve

Technical field

The utility model provides a kind of valve, especially a kind of valve that utilizes magnetic force.

Background technique

Magnetic valve is contactless interlock valve, can effectively prevent from during use to leak.In the present magnetic valve solenoid valve is arranged, but using process needs power supply.The magnetic valve that also has a kind of need to rotate with handwheel, complex structure, and unlatching, closing motion are slow, and using effect is relatively poor.Someone has designed a kind of magnetic and has pushed away valve, but the inboard lower surface of its shielding can is a plane, and the scope that valve rod moves up and down is little, therefore is mainly used in rock gas, liquid gas etc., can not be used for the control of fuel line.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of magnetic valve, to improve the scope that moves up and down of valve rod.

The utility model is to realize like this, a kind of magnetic valve, it has valve body, is fixed with shielding can on the valve body, and protective housing is installed above the shielding can, be set with valve rod in the shielding can, valve rod upper end is fixed with the magnetic post, the lower end is connected on the valve seat, diaphragm is arranged below the valve seat, and diaphragm edge is fixed between valve body and the shielding can, the bottom that top is exposed at the depression bar of protective housing outside is equipped with magnet ring, and the inboard lower surface of described shielding can is a conical surface.

Adopt the magnetic valve of said structure, because the inboard lower surface of shielding can is a conical surface, thereby has improved the scope that moves up and down of valve rod, makes this magnetic valve both can be used for the control of rock gas, liquefied gas pipeline, also can be used for the control of fuel line, applied range.

Description of drawings

Fig. 1 is the schematic representation of the utility model structure.

Fig. 2 is the schematic representation of extension bar and depression bar annexation.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.

As shown in drawings, a kind of magnetic valve of the utility model, it has valve body 8, is fixed with shielding can 3 on the valve body, and protective housing 2 is installed above the shielding can, be set with valve rod 9 in the shielding can, valve rod upper end is fixed with magnetic post 5, the lower end is connected on the valve seat 11, diaphragm 7 is arranged below the valve seat, and diaphragm edge is fixed between valve body and the shielding can, the bottom that top is exposed at the depression bar 1 of protective housing outside is equipped with magnet ring 4, and the inboard lower surface 31 of described shielding can 3 is a conical surface.

It is identical that the working principle of this magnetic valve and existing magnetic push away valve, no longer describes in detail.

Lining net 71 is arranged in described diaphragm 7.The lining net can be plastic wire or wire netting.Can improve the working life of diaphragm like this.

On described depression bar 1 extension bar 12 is installed, extension bar upper end is fixed with bow 13, between the bottom of magnet ring 4 and shielding can 3 spring 6 is arranged.The shape of bow and the bottom shape of kitchen range adapt.This magnetic valve can be used on the fuel channel of kitchen tools, and when kitchen range such as pot were placed on the kitchen tools, kitchen range were depressed depression bar by extension bar, and magnetic valve is opened.When kitchen range break away from kitchen tools, no longer push down extension bar.Depression bar is upspring under the effect of the elastic force of spring, and magnetic valve cuts out automatically.Can improve the convenience of use like this.

The valve rod lower end can be connected on the valve seat 11 by extension spring 10.
