Description
Technical Field
The utility model is used for the compressor field especially relates to a jet check valve structure, scroll compressor and the thermoregulation device that increases the enthalpy.
Background
At present, in order to satisfy the demand of scroll compressor to the operating mode, usually can be equipped with for the compressor and spray the enthalpy system that increases, through control system's control with the refrigerant direct injection to the middle vortex compression chamber that constitutes by fixed scroll dish and motion scroll dish, the compressor carries out the secondary compression to it, like this alright furthest utilize the effective volume of compressor, improve compressor system mass flow to reach the purpose that improves the system heating volume. Meanwhile, the injected refrigerant is directly injected into the middle vortex compression cavity, and the refrigerant can play a role in cooling the vortex plate and reducing the exhaust temperature, so that the reliability of the compressor is also improved. However, after the air injection enthalpy-increasing pipe is added, particularly when refrigerant does not need to be injected under partial working conditions, the internal pressure of the compression cavity is always in a changing state, and the refrigerant in the pipe moves back and forth between the compression cavity and the air injection enthalpy-increasing pipe along with the pressure change of the compression cavity, so that the air injection enthalpy-increasing pipe vibrates greatly, the piping is likely to break due to long-time vibration, and the reliability cannot be guaranteed. At present, a manufacturer generally uses a silencer and a configuration hose when designing a system, and a plurality of devices for fixing pipelines are added to reduce the vibration of the pipelines, but the damping effect is general, and the cost is high during batch production. Therefore, some compressor manufacturers add a structure of a one-way valve in an injection enthalpy-increasing system of the compressor, so that the pressure pulsation of a refrigerant in an injection enthalpy-increasing pipe in the operation process of the compressor is reduced, and the vibration of the injection enthalpy-increasing pipe is reduced.
In the prior art, most of injection enthalpy-increasing compressors with one-way valves adopt a straight hole formed in a fixed scroll as an injection hole, and a wing plate is connected with an injection pipe, a check valve and a return spring. The check valve and the small hole on the contact surface of the end surface of the lower end of the wing plate are used as a circulation hole of the refrigerant, when the injection is started, the check valve can be opened, and the refrigerant flows to the injection hole on the fixed scroll plate through the small hole on the check valve, so that the refrigerant is injected into the compression cavity to realize the injection enthalpy increase of the compressor. However, such a structure has the following disadvantages:
1. because the internal pressure of the compression cavity is always in a changing state, the refrigerant in the pipe can move back and forth between the compression cavity and the air injection enthalpy increasing pipe along with the pressure change of the compression cavity, when the air injection is started, the valve plate is pressed to be opened, the air flow passes through the small hole of the valve plate and flows into the compression cavity, the pulsation generated by the pressure change of the air flow at the moment can drive the valve plate to vibrate, the vibration of the valve plate can be aggravated, the abrasion of the valve plate is aggravated, the failure of the valve plate and the spring can be possibly caused, and the service life of the valve plate and the spring is short;
2. because the position of the opening on the check valve plate is positioned at the joint of the valve plate and the lower end face of the wing plate, the position and the size of the opening are limited to a certain extent;
3. the size of the opening is limited, so that the adhesion force reduction space between the check valve plate and the lower end face of the wing plate is limited, the reduction space of the injection resistance is limited, and the movement flexibility of the check valve is influenced;
4. the holes formed in the check valve sheet can also cause the overall strength of the check valve to be low, and the failure of the check valve can be caused by vibration aggravation due to the fact that the overall strength of the check valve is low under the condition that the air flow pulsation causes pulsation of the check valve sheet. And the check valve plate is perforated to increase the processing steps and the processing cost.
