Abstract
The utility model discloses a proportional valve which comprises a valve body; a valve core is installed inside the valve body; a channel is arranged in the valve core; and a spring is hitched on the valve core. The proportional valve is characterized in that a rubber gasket ring is arranged in the valve body; and when the valve core is pressed down to certain position, the rubber gasket ring can block the channel of the valve core. Making use of good elasticity of rubber and adopting rubber and plastic to seal, the proportional valve is improved in sealing effect, thereby reducing accessory precision requirements and installation precision requirements and enabling the production to progress smoothly.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of proportional valve that is used for aerosol products packing jar.
Background technology
Be used for the quantitative valve on the aerosol products packing jar, comprise valve body, spool is installed in the valve body, when pressing bottom spool, agent liquid in the valve body passes through the ejection of spool aperture, and spool lower end valve body is closed with a jar interior agent liquid interface channel simultaneously, thereby reaches each quantitatively purpose of ejection.But closing of traditional quantitative valve interface channel is the contact seal that directly utilizes between spool and the valve body, promptly seal by the plastics of making two parts, there is valve resilience difficulty when cooperating tension in this hermetically-sealed construction, and cooperates Song Shiyou to lose the shortcoming of quantitative function.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of proportional valve of good sealing effect.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of proportional valve comprises valve body, and spool is installed in the valve body, is provided with passage in the described spool, and valve core upper sleeve is equipped with spring, but it is characterized in that being equipped with in the described valve body rubber seal of shutoff valve core channel when spool presses to certain position.
As the utility model improvement of the technical scheme, an end of described spring is pressed on the rubber seal.
Be fixedly connected with fixing body on the above-mentioned valve body, be provided with outer washer in the fixing body.
The beneficial effects of the utility model are: the utility model is equipped with rubber seal in valve body, utilize the rubber better elastic,, improved the sealing effectiveness of proportional valve by rubber-plastic seal, thereby reduced requirement, production can be carried out smoothly product component and assembly precision.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, the disclosed a kind of proportional valve of the utility model, comprise valve body 1, be fixedly connected with fixing body 2 on the valve body 1, fixing body 2 is used for proportional valve is installed in the aerosol jar, in fixing body 2, be provided with outer washer 3, spool 4 is installed in valve body 1, wherein in spool 4, be provided with passage 5, be set with spring 6 on the spool 4, and but the rubber seal 7 of shutoff valve core channel 5 when spool 4 presses to certain position is installed in valve body 1, an end of spring 6 is pressed on the rubber seal 7, thereby utilizes the rubber better elastic, by rubber-plastic seal, improve the sealing effectiveness of proportional valve, reduce requirement, production can be carried out smoothly product component and assembly precision.
Claims (3)
