Abstract

The utility model relates to a valve core of a gas proportioning valve. The valve core comprises a valve core body, a valve core rubber gasket, an epithelium tray, an epithelium, a check ring, a magnetic base, a permanent magnetic magnet and a cover body, wherein the valve core body comprises a rubber gasket base, a rod part and a connecting post which is positioned on the end surface of the rod part, the valve core rubber gasket is arranged on the rubber gasket base, the connecting post passes through the epithelium tray, the epithelium and a connecting base of the magnetic base and then is clamped with the check ring, a containing cavity with an upper opening is formed in the upper end of the magnetic base, the permanent magnetic magnet is arranged in the containing cavity, and the cover body is buckled with the upper opening of the containing cavity and is detachably connected with the magnetic base. Because such a structure is adopted, the permanent magnetic magnet is put into the containing cavity, then the cover body covers the upper opening of the containing cavity and is abutted with the permanent magnetic magnet, and the cover body is detachably connected with the magnetic base by directly pressing the cover body. The valve core has the advantages of convenience in operation and firmness.

Description

A kind of spool of gas ratio valve

Technical field

The utility model relates to a kind of gas ratio valve, especially a kind of spool of gas ratio valve.

Background technique

Currently available technology, a kind of spool of gas ratio valve, comprise spool body, spool rubber cushion, epithelium pallet, epithelium, back-up ring, magnetic receiver and permanent magnetic iron, described spool body comprises rubber cushion seat, bar portion and is positioned at the attachment post on bar end surface, spool rubber cushion is arranged on rubber cushion seat, and attachment post engages with back-up ring through the connecting base of epithelium pallet, epithelium and magnetic receiver; There is the holding cavity of a upper shed described magnetic receiver upper end, and permanent magnetic iron is arranged in holding cavity.Existing problems are: permanent magnetic iron is fixing inconvenient.

Model utility content

The purpose of this utility model is: a kind of spool of gas ratio valve is provided, and it has permanent magnetic iron convenient fixing, and feature firmly.

The utility model is achieved in that a kind of spool of gas ratio valve, comprise spool body, spool rubber cushion, epithelium pallet, epithelium, back-up ring, magnetic receiver and permanent magnetic iron, described spool body comprises rubber cushion seat, bar portion and is positioned at the attachment post on bar end surface, spool rubber cushion is arranged on rubber cushion seat, and attachment post engages with back-up ring through the connecting base of epithelium pallet, epithelium and magnetic receiver; There is the holding cavity of a upper shed described magnetic receiver upper end, and permanent magnetic iron is arranged in holding cavity; Its special way is: also comprise a lid, the upper shed of described lid and holding cavity fastens, and lid can be connected with magnetic receiver in demolition.

The spool of described a kind of gas ratio valve, its special way is: on the outer circumferential surface of described magnetic receiver, have connecting base; On described lid, there is link; Link detachably coordinates with connecting base.

The spool of described a kind of gas ratio valve, its special way is: on described connecting base, have the hole clipping axially connecting along magnetic receiver;

Described link comprises bar portion and hook portion, and described bar portion is through hole clipping, hook portion and hole clipping end fastening.

The spool of described a kind of gas ratio valve, its special way is: jagged in the periphery of described rubber cushion seat, in the axial walls of described breach, there is annular protrusion perpendicular to axial direction;

On the center hole wall of described spool rubber cushion, have annular groove, spool rubber cushion is enclosed within the axial walls of breach, and annular protrusion and annular groove are chimeric; Axial one end of spool rubber cushion and the laminating of the radial wall of breach.

The spool of a kind of gas ratio valve of the utility model, owing to adopting such structure, permanent magnetic iron is put into holding cavity, then lid is covered holding cavity upper shed and with permanent magnetic iron laminating, directly press that lid just can be realized lid and magnetic receiver removably connects; Easy to operate, and firmly.
