Problems solved by technology

[0004] However, in some cases, when the scroll compressor stops, the valve plate may be affected by the adhesion of lubricating oil or the pressure difference on both sides of the valve plate is not enough to quickly close the valve hole downwards, resulting in reverse rotation noise at shutdown And bring the risk of wear and damage to parts; in addition, when the scroll compressor is working, the valve plate may not be able to maintain the upper open position stably, resulting in working noise and affecting the reliability of the scroll compressor

Embodiment Construction

[0035] The following descriptions of various embodiments of the present disclosure are merely exemplary, and by no means limit the present disclosure and its application or usage. The same reference numerals are used to denote the same components in the respective drawings, and thus the configurations of the same components will not be described repeatedly.

[0036] In addition, in the following description, the structure of the check valve according to the present disclosure will be described by taking the application of the check valve in a scroll compressor as an example. However, it can be understood that the one-way valve structure according to the present disclosure is not limited to the scroll compressor, and it can be applied to any applicable application.

[0037] The following will refer to Figure 1-3 A check valve 100 according to a comparative example will be described, in which, figure 1 An exploded perspective view of a one-way valve 100 according to a compara...

Abstract

The present disclosure provides a one-way valve and a scroll compressor. The one-way valve comprises a valve seat in which a valve hole through which a fluid passes is formed, a valve plate which is disposed above the valve seat and is set to selectively open or close a valve hole, a valve block which is arranged above the valve plate and fixedly connected to the valve seat and comprises a stop part for limiting the maximum displacement range of the valve plate and a guide part for guiding the valve plate to move, and a flow guide piece set to guide the fluid flowing through the one-way valveto control a force applied to the valve plate by the fluid. According to the one-way valve, the flow guide piece is used for controlling the flowing direction of the fluid such that the purposes of reducing the working noise and the shutdown noise of the scroll compressor and improving the efficiency and the working reliability of the scroll compressor are achieved.

Description

technical field [0001] The present disclosure relates to a one-way valve and a scroll compressor including the one-way valve. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] In the field of scroll compressors, in order to prevent the scroll compressor from reversing when it is shut down, a check valve is usually installed in the scroll compressor. This one-way valve includes a valve seat formed with a valve hole, a valve plate capable of opening or closing the valve hole, and a valve stopper that limits the displacement range of the valve plate and guides the movement of the valve plate. When the scroll compressor is working, the fluid discharged from the valve seat below the valve plate acts on the valve plate to move it upward, thereby opening the valve hole to allow fluid flow through the one-way valve. When the scroll compressor stops, the val...
