[0002] For traditional scroll compressors, when the compressor stops during operation, the pressure on the exhaust side is higher than the pressure in the scroll chamber. If the refrigerant returns, the compressor will reverse and produce very loud noises.
[0003] Traditional check valve design such as figure 1 and 2 The design shown is a single valve plate, and there is a greater risk of fracture when used on special models, which will lead to failure of the compressor

Embodiment Construction
[0031] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In order to achieve the object of the present invention, in some embodiments of a check valve and a scroll compressor including the check valve, such as Figure 3-5 As shown, the check valve includes:
[0032] The valve seat bottom plate 3, the valve seat bottom plate 3 is set at the exhaust port 1 on the back of the fixed scroll 2, and there are two bottom plate through holes 31 on the valve seat bottom plate 3, and the bottom plate through holes 31 communicate with the exhaust port 1 ;
[0033] The valve plate 4 is arranged between the valve seat bottom plate 3 and the valve seat 5. The valve plate 4 includes: a valve plate fixed connection portion 41 and two valve plate feet 42 connected with the valve plate fixed connection portion 41, the valve plate feet 42 The number is consistent with the number of bottom plate through holes 31, and t...

The invention discloses a check valve and a scroll compressor with the check valve. The check valve comprises a valve seat base plate, a valve block, a valve seat and fasteners, wherein the valve seatbase plate is arranged on an exhaust opening on the back side of a static scroll plate, at least two base plate through holes are formed on the valve seat base plate, the base plate through holes communicate with the exhaust opening, the valve block is arranged between the valve seat base plate and the valve seat, the valve block comprises a valve block fixed connection portion and at least two valve block feet connected with the valve block fixed connection portion, wherein the number of the valve block feet is equal to that the base plate through holes, one end of each valve block foot covers the corresponding base plate through hole, the valve seat is arranged on the valve block, the structure of the valve seat is matched with the valve block, and the fasteners are used for fixing thevalve seat base plate, the valve block and the valve seat to the static scroll plate. The check valve adopts design of multiple exhaust through holes, so that the communicating area can be effectivelycontrolled, and the check valve is suitable for different types and displacements of compressors; and valve block stress caused by a pressure difference when the compressor stops is effectively lowered, deformation of the valve block is reduced, and the service life of a valve body is greatly prolonged.
Description
technical field [0001] The invention specifically relates to a check valve and a scroll compressor including the check valve. Background technique [0002] For traditional scroll compressors, when the compressor stops during operation, the pressure on the exhaust side is higher than the pressure in the scroll chamber. If the refrigerant returns, the compressor will reverse and produce very loud noises. [0003] Traditional check valve design such as figure 1 and 2 The one shown is a single-valve design, and there is a greater risk of fracture when used on a special model, resulting in failure of the compressor. Contents of the invention [0004] In order to solve the above technical problems, the present invention proposes a check valve and a scroll compressor including the check valve. Compared with the traditional check valve, the check valve can greatly improve the service life, and is suitable for various There are different series of scroll compressors, which are u...
