Abstract
The utility model discloses a suction belt multipurpose check valve for a compressor, which comprises a valve body and a valve rod, wherein the valve body is provided with the valve rod; the left end of the valve rod is provided with a valve guide rod; the valve guide rod is embedded in the valve rod; the left end of the valve guide rod is provided with a check valve; the periphery of the valve rod and the middle valve guide rod of the check valve is provided with a check spring; the left side of the check valve is provided with a check valve gasket; the left side of the check valve gasket is provided with a pipeline connector; the upper end of the valve body is provided with a multipurpose connector; and the lower end of the valve body is provided with a compressor suction connector. According to the suction band multipurpose check valve for the compressor, the phenomenon that partial high-temperature and high-pressure gas in the compressor is not leaked into an evaporator is avoided when the compressor is under the halt state, and the refrigeration coefficient is improved.
Description
Technical field
The utility model relates to a kind of compressor air suction band non-return and uses valve more.
Background technique
Compression-type refrigerating system is by vaporizer, compressor, condenser; Parts such as expansion valve are formed cooling cycle system, and the groundwork process is that liquid refrigerant absorbs after the external heat in vaporizer, is vaporized into low-temperature low-pressure refrigerant gas; This gas machine that is compressed enters condenser after sucking and being compressed into high temperature and high pressure gas, and the medium that in condenser, is cooled (water or air) heat release is condensed into highly pressurised liquid, after expansion valve throttling step-down, is the refrigeration agent of low-pressure low-temperature; And get into vaporizer heat absorption vaporization once more; Reaching the beginning duplicates cold circulation, and in problem: after compressor shutdown, the part high temperature and high pressure gas in the compressor can leak in the vaporizer through valve; Can increase the load of compressor when working once more, reduce coefficient of refrigeration.
The model utility content
The utility model provides a kind of compressor air suction band non-return to use valve more, has overcome after compressor shutdown, and the part high temperature and high pressure gas in the compressor can leak in the vaporizer through valve, can increase the load of compressor when working once more, reduces coefficient of refrigeration.
For overcoming above-mentioned shortcoming, the technological scheme of the utility model is:
A kind of compressor air suction band non-return is used valve more, comprises valve body and the valve rod that is installed in the valve body; One end of described valve rod is equipped with the valve guide rod, and the valve leader casing is contained in the valve rod; On the valve guide rod check valve is installed, the check valve sealing gasket is installed on the check valve; Be set with check spring on the described valve guide rod; In the valve body of described check valve one side pipe joint is installed; Described valve body lower end is equipped with the compressor air suction interface.
Described valve body upper end is equipped with multi-purpose interface.
The beneficial effect of the utility model is: the utility model provides a kind of compressor air suction band non-return to use valve more; After compressor shutdown; Can make the refrigeration agent in the vaporizer constant in saturation state; Part high temperature and high pressure gas in the compressor is leaked in the vaporizer through valve, improve coefficient of refrigeration; In addition, because compressor air suction band non-return is used the non-return effect of valve, can make the pressure rising in the compressor reach parastate more, reduce compressor starting torque, energy efficient increases the compressor life-span.

Fig. 2 is the structural representation of the utility model working state.
Embodiment
Below in conjunction with accompanying drawing a nearly step being done in the enforcement of the utility model describes in detail.
Like Fig. 1, shown in Figure 2, a kind of compressor air suction band non-return of present embodiment is used valve more, comprises valve body 1 and the valve rod 2 that is installed in the valve body 1; Described valve rod 2 one ends are equipped with valve guide rod 3, and valve guide rod 3 is sleeved in the valve rod 2; Check valve 5 is installed on the valve guide rod 3, check valve sealing gasket 6 is installed on the check valve 5; Be set with check spring 4 on the described valve guide rod 3; In the valve body 1 of described check valve 5 one sides pipe joint 8 is installed; Described valve body 1 lower end is equipped with compressor air suction interface 7.Described valve body 1 upper end is equipped with multi-purpose interface 9.
A kind of compressor air suction band non-return of present embodiment is used valve more, and when compressor was in running order, valve rod 2 promoted valve guide rod 3; Check spring 4 is compressed; Valve guide rod 3 promotes check valve 5 and sealing gasket 6, makes sealing gasket 6 seal up pipe joint 8, and safety check is in closed condition; Refrigeration agent gets in the compressor through compressor air suction interface 7, discharges through multi-purpose interface 9 again; When compressor was started from outage state, when valve rod 2 left valve guide rod 3, check spring 4 was under the effect of elastic force; Push check valve 5 and sealing gasket 6 to pipe joint 8; Make sealing gasket 6 seal up pipe joint 8, this moment, safety check was in running order, can make the refrigeration agent in the vaporizer constant in saturation state; Part high temperature and high pressure gas in the compressor is leaked in the vaporizer through valve, improve coefficient of refrigeration; In addition, because compressor air suction band non-return is used the non-return effect of valve, can make the pressure rising in the compressor reach parastate more, reduce compressor starting torque, energy efficient increases the compressor life-span.
Claims (2)
