Description
Technical field
The utility model relates to a kind of single screw compressors with gas supplementary structure.
Background technique
Semi-enclosed single screw compressor, main motion parts are that main rotor and the star-wheel being arranged symmetrically in two sides turn
Dynamic component, belongs to positive displacement compressor.In order to improve the compressed capability of gas, gas supplementary structure can be generally added on the compressor,
To solve compressor excessive discharge temperature and the problems such as insufficient heating capacity under worst cold case；But traditional gas supplementary structure
Air compensation it is smaller, influence the effect of Gas-supplying enthalpy-increasing.
Utility model content
The purpose of this utility model is to provide a kind of single screw compressor with gas supplementary structure, structurally reasonable, energy
Enough effective increase air compensations, and the gas in compressor is prevented to flow backwards to blowdown pipe, to promote the effect of Gas-supplying enthalpy-increasing.
To achieve the above object, the technical solution of the utility model is to design a kind of single screw rod compression with gas supplementary structure
Machine, including casing, the first blowdown pipe, the second blowdown pipe, the first tonifying Qi connector and the second tonifying Qi connector；It is formed in the casing
Low pressure stage and intermediate pressure section, which is equipped with the first tonifying Qi port being connected to low pressure stage and second be connected to intermediate pressure section is mended
Gas port；The outlet end of first blowdown pipe is connect by the first tonifying Qi connector with the first tonifying Qi port, first blowdown pipe
It is equipped with the first check valve towards the first tonifying Qi port, the outlet end of second blowdown pipe passes through the second tonifying Qi connector and the
The connection of two tonifying Qi ports, second blowdown pipe are equipped with the second one-way valve towards the second tonifying Qi port.
Preferably, the shape of first tonifying Qi port and the second tonifying Qi port is round, ellipse or rectangle.
Preferably, the casing outer wall is equipped with several vertical bar shaped reinforcing ribs, and several vertical bar shaped reinforcing ribs are along casing
Circumferential setting, and single vertical bar shaped reinforcing rib is arranged along the axial direction of casing.
Preferably, the vertical bar shaped reinforcing rib and casing, which are integrally formed, is arranged.
Advantages and beneficial effects of the utility model lie in that by the first blowdown pipe and the second blowdown pipe respectively to compressor
Low pressure stage and intermediate pressure section carry out tonifying Qi and to increase air compensation promote the effect of Gas-supplying enthalpy-increasing.Also, pass through setting first
Check valve and second one-way valve, the gas effectively prevented in low pressure stage and intermediate pressure section are mended to the first blowdown pipe and second respectively
Tracheae is flow backwards.In addition, can effectively improve the intensity of casing by the way that vertical bar shaped reinforcing rib is arranged on the outer wall of casing.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1, a kind of single screw compressor with gas supplementary structure, including casing 1, the first blowdown pipe 2, second are mended
Tracheae 3, the first tonifying Qi connector 4 and the second tonifying Qi connector 5；It is formed with low pressure stage and intermediate pressure section in the casing 1, is set on the casing
The the second tonifying Qi port 7 for having the first tonifying Qi port 6 being connected to low pressure stage and being connected to intermediate pressure section；First blowdown pipe 2
Outlet end connect with the first tonifying Qi port 6 by the first tonifying Qi connector 4, first blowdown pipe 2 is equipped with the first tonifying Qi of direction
The outlet end of first check valve 8 of port 6, second blowdown pipe 3 is connected by the second tonifying Qi connector 5 and the second tonifying Qi port 7
It connects, which is equipped with the second one-way valve 9 towards the second tonifying Qi port 7.
Also, the shape of above-mentioned first tonifying Qi port 6 and the second tonifying Qi port 7 is round, ellipse or rectangle.
In addition, 1 outer wall of said machine casing is equipped with several vertical bar shaped reinforcing ribs, several vertical bar shaped reinforcing ribs are along casing 1
Circumferential setting, and single vertical bar shaped reinforcing rib is along the axial direction setting of casing 1.
Above-mentioned vertical bar shaped reinforcing rib and casing 1, which are integrally formed, to be arranged.
Advantages and beneficial effects of the utility model lie in that by the first blowdown pipe 2 and the second blowdown pipe 3 respectively to compression
The low pressure stage and intermediate pressure section of machine carry out tonifying Qi and promote the effect of Gas-supplying enthalpy-increasing to increase air compensation.Also, pass through setting the
One check valve 8 and second one-way valve 9 effectively prevent the gas in low pressure stage and intermediate pressure section respectively to 2 He of the first blowdown pipe
Second blowdown pipe 3 is flow backwards.In addition, can effectively improve casing 1 by the way that vertical bar shaped reinforcing rib is arranged on the outer wall of casing 1
Intensity.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
