Deng, in compressor operating, in motor cavity substantial amounts of lubricating oil can follow refrigerant enter refrigeration pipeline in, the refrigerant of circulation
Band oil mass is excessive, this will influence the performance of refrigeration system.
Utility model content
In order to solve the problems in the existing technology, the utility model provides a kind of oil level of Semi-closed piston compressor
Control device, can solve the problems, such as that existing refrigerant band oil mass is big during compressor operating.
The technical solution of the utility model is as follows：
A kind of oil level control device of Semi-closed piston compressor, including case partition, valve body and activity template, compressor
Motor cavity and shoe cream room are located at case partition both sides, and the through hole of a connection motor cavity and shoe cream room, valve body installation are set on partition plate
The through hole of shoe cream room side, through hole set an activity template close to shoe cream room side, and stent plays position-limiting action to activity template, works as storage
When the oil level of oil pocket is higher than motor cavity, activity template is located at valve body lowermost end, and activity template is by between motor cavity and shoe cream room at this time
Passage is shut, and lubricating oil will not flow into motor cavity from shoe cream room；When the oil level in motor cavity is higher than shoe cream room, in motor cavity
Lubricating oil flows into shoe cream room after activity template is pushed away valve body bottom, and the one-way flow of lubricating oil, oil storage are realized by activity template
The lubricating oil of chamber will not flow direction motor chamber, the refrigeration oil of motor cavity can flow to shoe cream room, only be had in such motor cavity a small amount of
Lubricating oil, refrigerant band oil mass is very low during compressor operating.
Wherein, the stent that position-limiting action is played to activity template is provided with the valve body.
Wherein, the stent both sides are provided with sealing ring, prevent the oil stream in shoe cream room from entering motor cavity.
Wherein, the top that the valve body is located in shoe cream room is provided with baffle ring, and a certain number of perforates are provided with baffle ring.
Wherein, the valve body is disposed in proximity to the position of shoe cream room bottom, and small more than zero degree with the formation of shoe cream room base
The angle of Yu Jiushi degree.
The utility model has the advantages that：
1st, the utility model can solve the problems, such as that existing refrigerant band oil mass is big during compressor operating.
2nd, the utility model is simple in structure, is easy to dismount.
Brief description of the drawings
Fig. 1 is the sectional structural map of the oil level control device of the utility model Semi-closed piston compressor.
Reference numeral is expressed as in figure：
1- valve bodies, 2- stents, 3- baffle rings, 4- activity templates, 5- sealing rings, 6- shoe cream rooms, 7- motor cavities, 8- case partitions.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of oil level control device of Semi-closed piston compressor, including case partition 8, valve body 1 and activity
Piece 4, the motor cavity 7 and shoe cream room 6 of compressor are located at 8 both sides of case partition, a connection motor cavity 7 and oil storage are set on partition plate 8
The through hole of chamber 6, valve body 1 install the through hole of 6 side of shoe cream room, and through hole sets an activity template 4 close to 6 side of shoe cream room, works as storage
When the oil level of oil pocket 6 is higher than motor cavity 7, activity template 4 is located at 1 lowermost end of valve body, and activity template 4 is by motor cavity 7 and shoe cream room 6 at this time
Between passage shut, lubricating oil will not from shoe cream room 6 flow into motor cavity 7；When the oil level in motor cavity 7 is higher than shoe cream room 6,
Lubricating oil in motor cavity 7 flows into shoe cream room 6 after activity template 4 is pushed away 1 bottom of valve body.
Preferably, the stent 2 that position-limiting action is played to activity template 4 is provided with the valve body 1.
Preferably, 2 both sides of stent are provided with sealing ring 5, prevent the oil stream in shoe cream room 6 from entering motor cavity 7.
Preferably, the top that the valve body 1 is located in shoe cream room 6 is provided with baffle ring 3, and certain amount is provided with baffle ring 3
Perforate.
Preferably, the valve body 1 is disposed in proximity to the position of 6 bottom of shoe cream room, and is formed with 6 base of shoe cream room and be more than zero
Angle of the degree less than 90 degree.
The use process of the utility model：
Referring to Fig. 1, case partition 8, the storage of case partition 8 are provided with the motor cavity 7 and shoe cream room 6 of compressor housing
6 side of oil pocket is provided with valve body 1, activity template 4 is housed in valve body 1, stent 2 plays position-limiting action to activity template 4, when the oil of shoe cream room 6
