Abstract

The invention discloses an air pressure visible air valve which comprises a connector. An adjusting button is rotationally arranged at the top of the connector. An adjusting rod is fixedly connected to the adjusting button. A display window is formed in the side face of the adjusting rod. An air pressure identification block is arranged in the display window and slides in the display window. An air pressure quantity indicator lamp is further arranged on the side face of the adjusting rod. The display window is a narrow closed window. Due to the fact that the narrow display window is formed in the side face of the adjusting rod of the air pressure visible air valve and the sliding block capable of sliding according to the magnitude of the air pressure is arranged in the window, when the air pressure in a pipeline is changed, the position of the sliding block is changed, the change of the air pressure in the pipeline can be visually seen, and use of the air valve is greatly facilitated.

Description

The visual air valve of a kind of air pressure

Technical field

The present invention relates to a kind of air valve, or rather, is the visual air valve of a kind of air pressure.

Background technique

Air valve is the significant components on compresser cylinder, and it is responsible for suction and the discharge of gas.Traditional air valve is made up of valve seat, valve block, spring, lift limiter, bolt etc.

The air valve generally used at present intuitively can not arrive the change of gas in pipelines pressure in control body when gas flow, it is convenient not to use.

Summary of the invention

The present invention mainly solves the technical problem existing for prior art, thus provides a kind of and intuitively can observe the visual air valve of the air pressure of internal gas pressure.

Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:

The visual air valve of a kind of air pressure, comprise a connecting head, an adjusting knob is provided with rotationally at the top of described connecting head, described adjusting knob is fixedly connected with an adjustable lever, a display window is provided with in the side of described adjustable lever, in described display window, be provided with an air pressure home block, described air pressure home block slides in described display window.

As preferred embodiment of the present invention, the side of described adjustable lever is also provided with amount of gas pressure tutorial light.

As preferred embodiment of the present invention, described display window is the airtight window of thin-and-long.

Because the visual air valve of air pressure of the present invention to be provided with a long and narrow display window in the side of the adjustable lever of valve, a slide block that can slide according to air pressure size is provided with in window, when pipeline internal air pressure changes time, the position of slide block can change, can the change of very intuitively pigging road internal air pressure, thus greatly facilitate the use of air valve.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the perspective view of the visual air valve of air pressure of the present invention;

Fig. 2 is the perspective view of the visual air valve of air pressure in Fig. 1, is now another visual angle.

Embodiment

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

The invention provides and a kind ofly intuitively can observe the visual air valve of the air pressure of internal gas pressure.

As shown in Figure 1 and Figure 2, the visual air valve 1 of a kind of air pressure, comprise a connecting head 21, an adjusting knob 22 is provided with rotationally at the top of described connecting head 21, described adjusting knob 22 is fixedly connected with an adjustable lever 3, be provided with a display window 4 in the side of described adjustable lever 3, be provided with an air pressure home block 5 in described display window 4, described air pressure home block 5 slides in described display window 4.

As shown in Figure 1 and Figure 2, the side of described adjustable lever 3 is also provided with amount of gas pressure tutorial light 6.

As shown in Figure 1 and Figure 2, described display window 4 is the airtight window of thin-and-long.

The visual air valve of air pressure of this invention is provided with a long and narrow display window in the side of the adjustable lever of valve, a slide block that can slide according to air pressure size is provided with in window, when pipeline internal air pressure changes time, the position of slide block can change, can the change of very intuitively pigging road internal air pressure, thus greatly facilitate the use of air valve.

Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.

The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
