Description

With the air compressor of hand valve

Technical field

The utility model relates to a kind of valve, and more particularly, it relates to a kind of air compressor with hand valve.

Background technique

Traditional air compressor air outlet adopts ball valve to carry out on-off, although use ball valve technology maturation, when valve closing, favorable sealing property, but due to air compressor air pressure large, use in the presence of a harsh environment, ball valve is short for working life, and later maintenance is frequent, trouble, and market reaction is poor.

Therefore, need to develop a valve being exclusively used in air compressor, it is short to solve above-mentioned working life, the problems such as troublesome maintenance.

Model utility content

For prior art exist deficiency, the purpose of this utility model is to provide a kind of air compressor with hand valve, and structure is simple, practical, not only good seal performance, and safeguard, easy maintenance, use under being applicable to rugged environment.

For achieving the above object, the utility model provides following technological scheme: a kind of air compressor with hand valve, comprise body and air outlet, described air outlet is provided with hand valve, described hand valve comprises valve body and valve pocket, described valve body is tubular structure and has through medium channel, is provided with dividing plate in described medium channel, and medium channel is divided into left valve pocket and right valve chamber by described dividing plate;

Described valve pocket is sheathed on outside described valve body, the inwall of left and right valve pocket is equipped with the gas port with extraneous conducting, the inwall of described valve pocket is at least embedded with two seal rings, form seal space between two seal rings and valve outer wall, valve sleeving inner wall, and the axial distance between two seal rings is greater than the distance between two gas ports.

Further, the cylindrical shape of described valve pocket, and the longitudinal section of valve pocket is in " work " word shape structure;

The inwall of valve pocket is provided with the bulge loop for being embedded seal ring, and the high spot of valve pocket outer wall is provided with anti-skidding lines.

Further, described seal ring is " O " RunddichtringO, and the relative one side of two seal rings is equipped with annular opening;

And the surperficial distance to its center axis of valve outer wall increases gradually to both sides centered by dividing plate.

By adopting technique scheme, valve body is divided into two cavitys, when air compressor does not need to give vent to anger, valve pocket is pushed to the valve pocket side be connected with body, now, only be communicated with the gas port of a valve pocket in valve pocket, the pressurized air of discharging from this gas port is tightly sealed in valve pocket by two seal rings of valve pocket; When needs are vented, staff only need push valve pocket to centre, the gas port of left and right valve pocket is made all to be positioned at the passage of valve pocket, now, pressurized air just, another gas port inner by the gas port of valve pocket, this valve pocket, valve pocket and another valve pocket successively, realizes compressed-air actuated conducting.

Described air compressor adopts the mode of hand valve to replace traditional ball valve, structure is simple, practical, not only good seal performance, and safeguard, easy maintenance, be applicable to rugged environment.

Embodiment

Referring to figs. 1 through Fig. 3, the air compressor embodiment of the utility model with hand valve is described further.

A kind of for the air compressor with hand valve 3, comprise body 1 and air outlet 2, described air outlet 2 is provided with hand valve 3, described hand valve 3 comprises valve body 31 and valve pocket 32, described valve body 31 is tubular structure and has through medium channel 311, be provided with dividing plate 312 in described medium channel 311, medium channel 311 is divided into left valve pocket 313 and right valve chamber 314 by described dividing plate 312;

Described valve pocket 32 is sheathed on outside described valve body 31, the inwall of left and right valve pocket 314 is equipped with the gas port 315 with extraneous conducting, the inwall of described valve pocket 32 is at least embedded with two seal rings 321, form seal space between two seal rings 321 and valve body 31 outer wall, valve pocket 32 inwall, and the axial distance between two seal rings 321 is greater than the distance between two gas ports 315.

By adopting technique scheme, valve body 31 is divided into two cavitys, when air compressor does not need to give vent to anger, valve pocket 32 is pushed to the valve pocket side be connected with body 1, now, only be communicated with the gas port 315 of a valve pocket in valve pocket 32, the pressurized air of discharging from this gas port 315 is tightly sealed in valve pocket 32 by two seal rings 321 of valve pocket 32; When needs are vented, staff only need push valve pocket 32 to centre, the gas port 315 of left and right valve pocket 314 is made all to be positioned at the passage of valve pocket 32, now, pressurized air just, another gas port 315 inner by the gas port 315 of valve pocket, this valve pocket, valve pocket 32 and another valve pocket successively, realizes compressed-air actuated conducting.

Described air compressor adopts the mode of hand valve 3 to replace traditional ball valve, structure is simple, practical, not only good seal performance, and safeguard, easy maintenance, be applicable to rugged environment.

Further, the cylindrical shape of described valve pocket 32, and the longitudinal section of valve pocket 32 is in " work " word shape structure;

The inwall of valve pocket 32 is provided with the bulge loop 322 for being embedded seal ring 321, and the high spot of valve pocket 32 outer wall is provided with anti-skidding lines 323.

The cylindrical shape of valve pocket 32, convenient processing on the one hand, uniform force on the one hand, convenient for assembly and use, longitudinal section is in " work " word shape, and intensity is high, stable performance, the position of valve pocket 32 outside hub depression is applicable to staff and holds, operates, the structure at two, after being embedded seal ring 321, still can having enough thickness to ensure structural strength, bear compressed-air actuated impact and pressure;

The setting of anti-skidding lines 323 then prevents operator's hand sliding.

Further, described seal ring 321 is " O " RunddichtringO 321, and the relative one side of two seal rings 321 is equipped with annular opening 324;

And valve body 31 outer wall surface to the distance of its center axis increases gradually to both sides centered by dividing plate 312.

Adopt the sealing means of " O " RunddichtringO 321, used " O " RunddichtringO 321 and had the advantages that to do axially reciprocating and low-speed rotation, ensured in Long-Time Service process, the tightness of hand valve 3;

Meanwhile, the one side that two seal rings 321 are relative is equipped with annular opening 324, upper valve body 31 outer wall surface is coordinated to increase gradually to both sides centered by dividing plate 312 to the distance of its center axis again, the special construction of seal ring 321, compressed-air actuated immense pressure can be utilized, order about annular opening 324 place to increase, tightly conflict valve body 31 outer wall, increase sealing; The leaning structure of valve body 31 outer wall surface, especially when annular opening 324 increases, the reaction force of a side direction is provided, compressed air pressure is larger, seal tightr, while further improving sealability, also increase the resistance of valve pocket 32 movement, prevent valve pocket 32 because of the vibration produced during compressor operation autonomous.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.

It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
