Abstract
The utility model relates to an F25B refrigerator, refrigerating equipment or a refrigerating system on International Patent Classification (IPC), in particular to a suction end seat of a refrigerating screw compressor with a check valve. According to the technical scheme, the suction end seat comprises a suction end body (1). The suction end seat is characterized in that an end body sealing surface (2) is arranged on the suction end body (1), and the check valve (3) is arranged on the end body sealing surface (2). The suction end seat has the advantages that 1, the check valve arranged in the compressor replaces an external pipeline check valve, so that blow-by of high and low pressure sides of the compressor is effectively prevented, a suction pipeline in the design of the compressor is simplified, connecting components for external pipelines are reduced, and refrigerant gas leakage points are reduced; and 2, by adopting the structural design of the flap check valve, a filter of the compressor can be conveniently overhauled and cleaned, so that the suction resistance can be effectively reduced and the refrigerating quantity of the compressor is improved.
Description
Technical field
The present invention relates to F25B refrigerator on International Classification of Patents (IPC) through retrieval, and chiller plant or system's classification especially belong to the refrigeration helical-lobe compressor suction end base with safety check.
Background technique
high-speed rotary by twin-screw during helical-lobe compressor work transfers compression refrigerant gas, and the compression of gas produces a large amount of heats, the type of cooling of helical-lobe compressor is mainly leaned on the screw rod of the cooling High Rotation Speed of lubricant oil and is reduced delivery temperature, after compressor shutdown because there are larger pressure reduction in helical-lobe compressor exhaust side and suction side, on high-tension side like this lubricant oil will be forced into suction side and even be pressed onto in suction line, the phenomenon that will cause oil to hit when compressor starts next time, this phenomenon is very large to compressor harm, for prevent this phenomenon usually externally pipeline safety check is installed, but effect is bad, and inconvenience is installed.
Summary of the invention
The object of the present invention is to provide a kind of refrigeration helical-lobe compressor suction end base with safety check, collaborate to reach effective prevention compressor high and low pressure side, and reduce the effect of SCREW COMPRESSOR parts and leakage point.
The technical solution used in the present invention is: it comprises suction end body (1), it is characterized in that: be shaped with end body sealing surface (2) on described suction end body (1), on end body sealing surface (2), safety check (3) be housed.
Beneficial effect of the present invention is: 1, the present invention adopts the built-in safety check of compressor to replace the exterior line safety check, has effectively stoped the compressor high and low pressure side to be collaborated.Suction line is simplified more, reduced the connected element of exterior line, reduce the refrigerant gas leakage point; 2, owing to adopting the flap valve structural design, the compressor filter is cleaned in convenient maintenance, can effectively reduce inhalation resistance and improve compressor refrigerating capacity.
Description of drawings
Fig. 1 is principle of the invention figure
Wherein: 1, suction end body 2, end body sealing surface 3, safety check 31, non-return flap 32, flap fixing pin 33, spring 34, valve clack sealing surface.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Be illustrated in figure 1 as principle of the invention figure, the present invention comprises suction end body (1), it is characterized in that: be shaped with end body sealing surface (2) on described suction end body (1), on end body sealing surface (2), safety check (3) be housed.
Safety check described in the present invention (3) is to be connected with flap fixing pin (32), spring (33) respectively by non-return flap (31), and flap fixing pin (32) be connected with spring (33) form.Be shaped with valve clack sealing surface (34) on described non-return flap (31), and valve clack sealing surface (34) is flexibly connected with end body sealing surface (2).This design has reached between valve clack sealing surface (34) on non-return flap (31) and end face seal face (2) and need not gasket seal, directly adopts metal and metal can carry out plane sealing.
Claims (2)
1. refrigeration helical-lobe compressor suction end base with safety check, it comprises suction end body (1), it is characterized in that: be shaped with end body sealing surface (2) on described suction end body (1), on end body sealing surface (2), safety check (3) be housed.
2. the refrigeration helical-lobe compressor suction end base with safety check according to claim 1, it is characterized in that: described safety check (3) is to be connected with flap fixing pin (32), spring (33) respectively by non-return flap (31), and flap fixing pin (32) be connected with spring (33) form; Be shaped with valve clack sealing surface (34) on described non-return flap (31), and valve clack sealing surface (34) is flexibly connected with end body sealing surface (2).
