Description

Technical Field

[0001] The utility model belongs to the technical field of compressors, and in particular relates to an air release component and a static scroll plate. Background Art

[0002] A compressor is a driven fluid device that boosts low-pressure gas to high-pressure gas. It's the heart of the refrigeration system and consists of a housing, a head cover, a fixed scroll, and an orbiting scroll. The fixed scroll consists of the fixed scroll body and a bleed assembly, which includes a bleed valve, a limit plate, and fasteners.

[0003] The air relief assembly is assembled on the back of the fixed scroll body. During assembly, the air relief valve plate is sandwiched between the fixed scroll body and the limit plate and then locked in place with fasteners. Since the back of the fixed scroll body is usually designed to be flat, the following problems arise:

[0004] 1. Because there is no positioning mechanism, it is difficult to position and install the air relief valve plate and the limit plate on a flat surface;

[0005] 2. During the tightening process, the limit plate and the relief valve disc are prone to relative displacement, and the position of the relief valve disc and the limit plate are offset, which can easily lead to poor sealing of the relief valve disc;

[0006] 3. The relief valve plate is in contact with the static scroll body, and the contact area is large. The relief valve plate is constantly opening or closing during operation. Due to the pressure difference and elastic deformation, the relief valve plate hits the static scroll body when closing, generating a lot of noise. Utility Model Content

[0007] The purpose of the utility model is to provide a deflation component, which utilizes the mounting cavity for positioning to install the deflation valve plate and the limit plate, so as to realize fast and accurate alignment and installation of the deflation valve plate and the limit plate, which not only improves production efficiency but also avoids relative displacement of the deflation valve plate and the limit plate; the mounting seat and the discharge seat are arranged at intervals to effectively reduce noise.

[0008] The purpose of the utility model is achieved through such a technical solution, a deflation component, comprising:

[0009] The valve seat includes a mounting seat and a drain seat, which are spaced apart. The mounting seat is provided with a mounting cavity on its surface, and the drain seat is provided with a through hole.

[0010] The air release valve plate includes a stopper and a mounting portion, wherein the mounting portion is mounted in the mounting cavity, the inner wall of the mounting cavity abuts against the side wall of the mounting portion, and the stopper is mounted on the valve plate seat and is used to open or close the through hole;

[0011] The limiting plate is installed on the upper side of the air relief valve plate, and the inner wall of the installation cavity abuts against the side wall of the limiting plate.

[0012] Preferably, a gap is provided between the side wall of the stopper and the inner wall of the installation cavity.

[0013] Preferably, the through hole is provided with a recessed groove along its circumference.

[0014] Preferably, the limiting plate is provided with a first fixing hole, the air relief valve plate is provided with a second fixing hole, and the mounting seat is provided with a third fixing hole. The fixing member passes through the first fixing hole, the second fixing hole and the third fixing hole to fix the air relief valve plate and the limiting plate on the surface of the mounting seat.

[0015] Preferably, it also includes an arc-shaped platform, which is installed on the side of the excretion seat.

[0016] Another object of the present invention is to provide a static scroll disk that utilizes an air release assembly. After the static scroll disk is installed in the compressor, it has stable and reliable performance, which not only improves product performance but also effectively reduces noise.

[0017] The fixed scroll includes a fixed scroll body and an air leakage component, which is installed on the back of the fixed scroll body.

[0018] Preferably, an exhaust port corresponding to the through hole is provided on the back side of the fixed scroll body.

[0019] Due to the adoption of the above-mentioned technical solution, the present invention has the following advantages: the mounting cavity is used to coordinate the installation of the relief valve disc and the limit plate, achieving self-positioning of the relief valve disc and the limit plate, allowing for quick and accurate installation of the relief valve disc and the limit plate; the mounting cavity restricts the movement of the relief valve disc and the limit plate, thereby preventing relative displacement of the relief valve disc and the limit plate; the mounting seat and the discharge seat are spaced apart, leaving a relatively large gap between them, reducing the direct contact area between the stop portion of the relief valve disc and the discharge seat, effectively reducing the adsorption force between the relief valve disc and the refrigeration oil adhering to the discharge seat or the surface of the fixed scroll body, making the opening and closing of the relief valve disc smoother and eliminating noise, thereby overall enhancing the operating performance and reliability of the compressor.

DETAILED DESCRIPTION

[0026] See also Figure 1 and Figure 2 , a deflation assembly comprising:

[0027] The valve disc seat 1 includes a mounting seat 11 and a drain seat 12, which are spaced apart. The mounting seat 11 is provided with a mounting cavity 111, and the drain seat 12 is provided with a through-hole 121. The air relief valve disc 2 includes a stopper 22 and a mounting portion 21. The mounting portion 21 is mounted in the mounting cavity 111, and the inner wall of the mounting cavity 111 abuts against the side wall of the mounting portion 21. The stopper 22 is mounted on the valve disc seat 1 and is used to open or close the through-hole 121. The limit plate 3 is mounted on the upper surface of the air relief valve disc 2, and the inner wall of the mounting cavity 111 abuts against the side wall of the limit plate 3. Preferably, the air relief valve disc 22 is a high-carbon steel thin plate with elasticity.

[0028] In the deflation assembly of the present invention, the depth of the mounting cavity 111 is approximately equal to the sum of the thickness of the deflation valve disc 2 and half the thickness of the limit plate 3. The shape of the mounting cavity 111 matches the shape of the limit plate 3 and the shape of the deflation valve disc 2. When assembling the deflation valve disc 2 or the limit plate 3, the deflation valve disc 2 and the limit plate 3 are self-positioned by utilizing the shape matching installation, making the installation easy and positioning accurate. The deflation valve disc 2 and the limit plate 3 can be quickly installed without the need for preparing special tooling, thereby reducing costs and improving production efficiency. After assembly, the side walls of the deflation valve disc 2 and the limit plate 3 are both in contact with the side walls of the mounting cavity 111, preventing relative displacement of the deflation valve disc 2 and the limit plate 3, and ensuring that the deflation valve disc 2 seals the through hole 121. A large gap is left between the mounting seat 11 and the drain seat 12 to prevent the air relief valve plate 2 from contacting the drain seat 12 over a large area, effectively reducing the adsorption force of the air relief valve plate 2 on the valve plate seat 1, making the air relief valve plate 2 run more smoothly when opening or closing the through hole 121, and reducing the noise generated when the air relief valve plate 2 is closed.

[0029] See also Figure 3Furthermore, a gap is provided between the stopper portion 22 and the inner wall of the installation cavity 111. Specifically, the stopper portion 22 is provided with a bend away from the inner wall of the installation cavity 111 at the junction with the installation portion 21. The installation cavity 111 is an incompletely enclosed groove, and its shape matches the shape of the limit plate 3 and the shape of the air relief valve plate 2. The installation portion 21 of the air relief valve plate 2 abuts the inner wall of the installation cavity 111, and there is a gap between the stopper portion 22 and the inner wall of the installation cavity 111, so that when the air relief valve plate 2 is installed, the air relief valve plate 2 and the installation cavity 111 maintain an appropriate matching gap. The air relief valve plate 2 only needs to be slid into the installation cavity 111 to be quickly and accurately installed in place. The air relief valve plate 2 and the limit plate 3 have the same shape. After the air relief valve plate 2 and the limit plate 3 are installed in place, the installation cavity 111 limits the movement of the air relief valve plate 2 and the limit plate 3 in the horizontal and vertical directions respectively. The air release valve plate overlaps with the limiting plate to ensure the sealing performance of the air release valve plate to the through hole 121 .

[0030] See also Figure 1 , further, the through hole 121 is provided with a recessed groove 122 along the circumferential direction. Preferably, a main through hole 121 and two auxiliary through holes 121 are provided on the drain seat 12, and the auxiliary through holes 121 are respectively provided on both sides of the main through hole 121, and the three through holes 121 are on the same straight line. The stopper 22 is provided with three stopper portions 22 corresponding to one main through hole 121 and two auxiliary through holes 121. The through hole 121 is provided with a recessed groove 122 along the circumferential direction, and the recessed groove 122 can reduce the direct contact area between the relief valve plate 2 and the drain seat 12, effectively reducing the adsorption force between the relief valve plate 2 and the refrigeration oil adhered to the drain seat 12, so that the relief valve plate 2 operates more smoothly when opening or closing the through hole 121, and reduces the generation of noise.

[0031] See also Figure 1 and Figure 2 Furthermore, the limiting plate 3 is provided with a first fixing hole 31, the relief valve disc 2 is provided with a corresponding second fixing hole 23, and the mounting base 11 is provided with a corresponding third fixing hole 112. The fixing member 4 passes through the first fixing hole 31, the second fixing hole 23, and the third fixing hole 112 to secure the relief valve disc 2 and limiting plate 3 to the surface of the mounting base 11. Specifically, the first fixing hole 31, the second fixing hole 23, and the third fixing hole 112 are installed in an overlapping and corresponding manner, and the fixing member 4 passes through the first fixing hole 31, the second fixing hole 23, and the third fixing hole 112 for securing. Preferably, the fixing member 4 is a screw or bolt.

[0032] See also Figure 1 and Figure 2 Furthermore, the arc-shaped platform 5 is installed on the side of the drain seat 12. In order to prevent the internal refrigerant oil from being directly discharged from the compressor along with the high-temperature and high-pressure gas when the compressor is working, the arc-shaped platform 5 can make the high-temperature and high-pressure gas collide with it when it is ejected until it condenses into oil droplets, and then the oil is returned, thereby increasing the amount of returned oil.

[0033] A fixed scroll includes a fixed scroll body 6 and an air release assembly. The air release assembly is mounted on the back of the fixed scroll body 6.

[0034] See also Figure 1 Furthermore, an exhaust port corresponding to the through hole 121 is provided on the back of the fixed scroll body 6 for gas discharge.

[0035] By adopting the above-mentioned technical solution, the present invention has the following advantages: The mounting cavity 111 is used to coordinate the installation of the relief valve disc 2 and the limit plate 3, achieving self-positioning of the relief valve disc 2 and the limit plate 3, allowing for quick and accurate installation of the relief valve disc 2 and the limit plate 3. The mounting cavity 111 restricts the movement of the relief valve disc 2 and the limit plate 3, preventing relative displacement of the relief valve disc 2 and the limit plate 3. Because the mounting seat 11 and the drain seat 12 are spaced apart, a relatively large gap exists between them. Furthermore, the through-hole 121 is provided with a recessed groove 122 along its circumference, which reduces the direct contact area between the stopper 22 of the relief valve disc 2 and the drain seat 12. This effectively reduces the adsorption force between the relief valve disc 2 and the refrigerant oil adhering to the drain seat 12 or the surface of the fixed scroll body 6. This allows the relief valve disc 2 to operate more smoothly when opening or closing the through-hole 121, effectively eliminating noise and thereby enhancing the overall performance and reliability of the compressor. The arc-shaped platform 5 is installed on the side of the drain seat 12 to prevent the internal refrigeration oil from being directly discharged from the compressor along with the high-temperature and high-pressure gas when the compressor is working, thereby increasing the oil return volume.
