Abstract
The utility model relates to an air exhaust device for refrigeration compressors, comprising an air sucking silencing cavity and a cylinder seat. A valve plate assembly and a cylinder cover are sequentially connected. The air exhaust device for refrigeration compressors is characterized in that the valve plate assembly and the cylinder cover are provided with air vents. The cylinder seat is provided with an air exhaust groove. One end of the air exhaust groove is communicated with the air vents, and the other end is communicated with the air exhaust outlet of the sucking silencing cavity. An inner air exhaust connecting ring is arranged outside the air vent on the cylinder cover. An inner air exhaust pipe inlet system is arranged in the inner air exhaust connecting ring. The utility model solves the problem that a silencing cavity cover is not arranged when the air exhaust silencing cavity of the compressor is designed on the cylinder head, and thus the inner exhaust pipe is unable to be arranged. The air exhaust device for refrigeration compressors is particularly suitable for improving piston type refrigeration compressors.
Description
(1) technical field: the utility model relates to the improvement technology of compressor in the chiller plant, is a kind of refrigeration compressor venting gas appliance.
(2) background technique: at present, structural design generally adopts exhaust gas through entering system by being installed in the outlet pipe that inside exhaust pipe that silencing cavity covers connects on the compressor housing after the silencing cavity in the Piston Refrigerant Compreessor industry, but when the design of the exhaust noise silencing chamber of compressor is on cylinder head, do not had the silencing cavity lid, inside exhaust pipe can't be installed.
(3) summary of the invention: the purpose of this utility model is exactly will solve when the design of the exhaust noise silencing chamber of compressor is on cylinder head, there is not the silencing cavity lid, the problem that inside exhaust pipe can't be installed provides a kind of novel compressor air exhausting unit, makes gas enter system smoothly.
Concrete scheme of the present utility model is: the exhaust structure to existing refrigeration compressor improves, particularly: on valve board assembly and cylinder head, have exhaust port, have air vent on cylinder block, an end of air vent is communicated with above-mentioned exhaust port, and the other end is communicated with the relief opening of air-breathing silencing cavity; Exhaust fastener rings in being equipped with outside the vent ports on cylinder head has inside exhaust pipe to enter system with interior exhaust fastener rings tipping.
The connection of the exhaust port in the utility model on row's fastener rings and cylinder head is achieved in that in interior exhaust fastener rings both sides and adds washer sealing, adopts an external diameter to pass interior exhaust fastener rings and exhaust port spinning on cylinder block less than the screw of exhaust port.Its connection mode can also be bonding, welding, adopts screw to realize with multiple modes such as cylinder head are connected.
The utility model is ingenious have been solved when compressor does not have the silencing cavity lid, the problem that inside exhaust pipe can't be installed, and it is simple in structure, and is easy for installation.
(4) description of drawings:
Fig. 1 is the explosive view for the utility model general structure;
Fig. 2 is the linkage structure partial sectional view of exhaust fastener rings and cylinder head in the utility model, cylinder block.
Among the figure: 1-screw, exhaust fastener rings in the 2-copper washer, 3-, 4-inside exhaust pipe, 5-copper washer, 6-cylinder head, the air-breathing silencing cavity of 7-, 8-valve board assembly, 9-cylinder block, 10-air vent, 11-exhaust port.
(5) embodiment:
Referring to Fig. 1, the utlity model has the basic structure of prior art, include air-breathing silencing cavity 7, cylinder block 9, be connected successively with cylinder block 9 valve board assembly 8, cylinder head 6 are housed.Following improvement is arranged in the utility model: referring to Fig. 2, leave exhaust port 11 on cylinder head 6 and valve board assembly 8, leave air vent 10 on cylinder block 9, these air vent 10 1 ends are communicated with exhaust port 11, and the other end is communicated with the relief opening of air-breathing silencing cavity 7.Exhaust fastener rings 3 in loading onto outside the vent ports on cylinder head 6 then has inside exhaust pipe 4 to enter system with interior exhaust fastener rings 3 tippings and promptly constitutes the utility model.In the utility model, interior exhaust fastener rings 3 is to install like this: add copper washer 2 and 5 in interior exhaust fastener rings 3 both sides and seal, adopt external diameter to pass interior exhaust fastener rings 3 and exhaust port 11 less than the screw 1 of exhaust port, spinning gets final product on cylinder block 9.
Claims (2)
1. refrigeration compressor venting gas appliance, include air-breathing silencing cavity, and cylinder block, the valve board assembly of Lian Jieing, cylinder head successively, it is characterized in that: on valve board assembly and cylinder head, have exhaust port, have air vent on cylinder block, an end of air vent is communicated with above-mentioned exhaust port, and the other end is communicated with the relief opening of air-breathing silencing cavity; Exhaust fastener rings in being equipped with outside the vent ports on cylinder head has inside exhaust pipe to enter system with interior exhaust fastener rings tipping.
2. a kind of refrigeration compressor venting gas appliance according to claim 1 is characterized in that: interior exhaust fastener rings both sides add washer sealing, adopt an external diameter pass less than the screw of exhaust port in exhaust fastener rings and exhaust port spinning on cylinder block.
