Description

Inclined tube reservoir

Technical field

The present invention relates to a kind of reservoir, especially relate to a kind of inclined tube reservoir.

Background technology

Reservoir is widely used in various fields.For example, when being used for air-conditioning system, reservoir is an auxiliary element of compressor, it usually and compressor link together, the reservoir air inlet links to each other with evaporator outlet in the air-conditioning system, and escape pipe links to each other with compressor air suction.The air inlet of compressor enters reservoir from air inlet pipe, after being installed in the strainer filtering impurity on the filter screen bracket, enter the filter screen bracket lower cavity by the passage on the filter screen bracket, gas flow rate reduces in lower cavity, make the oil in the gas can be deposited on the reservoir bottom, flow back to compressor by spill port.The effect of reservoir is the storage liquid refrigerant, and when preventing that effectively compressor from moving under unsteady state, liquid refrigerant flows into compressor and causes liquid hammer, damages compressor pump.

In the design of existing reservoir, escape pipe bends 90 degree usually, thus fluid during through this bending angle fluid loss bigger.In addition, existing reservoir escape pipe is generally made by copper material, and the more cheap iron material of price is when carrying out bending process, because the material poor ductility, processing technology is very difficult, therefore is difficult to substitute copper pipe with cheap irony pipe in actual production.

Summary of the invention

The objective of the invention is to solve and improve the reservoir performance, reduce the reservoir cost simultaneously.

The invention provides a kind of reservoir, comprise: air inlet pipe, filter screen, filter screen bracket, escape pipe and housing, air inlet pipe stretches into and is opened in this housing from the top of housing, and escape pipe stretches into and is opened in this housing from lower part of frame, and the angle of escape pipe bending is less than 90 degree.

Beneficial technical effects of the present invention is, because the bending angle of escape pipe less than 90 degree, helps reducing the technology difficulty of bending, can substitute copper pipe with cheap irony pipe in actual production.In addition,, can significantly reduce the coefficient of partial resistance of pipeline, reduce fluid loss, improve the performance of reservoir owing to reduced the bending angle of escape pipe.

The specific embodiment

Present most reservoir is copper or iron cylindrical container, and structure comprises reservoir air inlet pipe 1, filter screen 2, support 3, escape pipe 4, housing 5 as shown in Figure 1.Wherein, air inlet pipe 1 is connected with the top of housing 5, and is opened in the housing 5.About 90 degree of escape pipe 4 bendings vertically stretch into the housing 5 with the bottom from housing 5, and are opened in the housing 5.Air inlet pipe 1 and escape pipe 4 centrally aligneds and longitudinally-spaced.Filter screen 2 and filter screen bracket 3 are arranged between air inlet pipe 1 opening and escape pipe 4 openings, are used for prevention system impurity and enter.Fluid flows into through reservoir air inlet pipe 1, after the through hole of filter screen 2, filter screen bracket 3 enters the reservoir inner chamber, flows out through escape pipe 4 again.

Fig. 2 represents reservoir internal structure schematic diagram of the present invention.Inclined tube reservoir of the present invention comprises air inlet pipe 1, filter screen 2, support 3, escape pipe 4 and housing 5.Wherein, air inlet pipe 1 stretches into the housing 5 from the top of housing 5, and is opened in the housing 5.Escape pipe 4 bending is less than 90 degree, stretching into the housing 5 from the bottom of shell body 5, and is opened in the housing 5.Since escape pipe 4 in vertical direction with an angle stretch in the housing 5, air inlet pipe 1 and escape pipe 4 in housing 5 along spaced, it is the center misalignment of air inlet pipe 1 and escape pipe 4, like this, air-flow can not flow directly in the escape pipe, guarantee oily separation effect, and made heavy impurity fall.Fig. 3 (a) and 3 (b) have represented existing reservoir escape pipe and reservoir escape pipe 4 of the present invention respectively, can clearly be seen that therefrom the escape pipe 4 of prior art has bent about 90 degree, and escape pipe of the present invention 4 bendings are less than 90 degree.Because the bending angle of escape pipe less than 90 degree, helps reducing the technology difficulty of bending, can substitute copper pipe with cheap irony pipe in actual production.In addition,, can significantly reduce the coefficient of partial resistance of pipeline, reduce fluid loss, improve the performance of reservoir owing to reduced the bending angle of escape pipe.

Since escape pipe 4 in vertical direction with an angle stretch in the housing 5, the escape pipe 4 of reservoir of the present invention is not to stretch into housing 5 in end cap 6 centers, but departs from end cap 6 centers.Therefore, the general spherical shape end cap shown in Fig. 4 (a) can not be applicable to the escape pipe 4 of reservoir of the present invention.In order to address this problem, the present invention has designed the end cap with local tabular surface, thereby makes escape pipe 4 non-ly centrally to be installed on the end cap 6, shown in Fig. 4 (b).

Filter screen 2 can be made multiple structural style satisfying under the condition of flow area, and this can select the easiest structure according to manufacture craft.Shown in Fig. 5 (a), the plain gauze support 3 of prior art is the air inlet screen support in even cloth hole.And in the present invention since escape pipe 4 in vertical direction with an angle stretch in the housing 5, a side of housing promptly is partial at the center that the opening of escape pipe 4 in housing 5 departs from housing 5.In order to prevent directly to enter into escape pipe 4 from the fluid that filter screen bracket 3 passes through, shown in Fig. 5 (b), filter screen bracket 3 of the present invention is designed to one-sided air inlet screen support.That is, the passage of filter screen 5 is arranged on a side relative with escape pipe 4 in housing, as shown in Figure 2.Like this, also prolonged path, improved the separating effect of gas, the performance of reservoir is provided with oil from passage to the air inlet mouth of pipe.

The above only is a preferred implementation of the present invention; but protection domain of the present invention is not limited thereto; any those skilled in the art is in technical scope disclosed by the invention; can change at an easy rate or change, and this change or variation all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
