Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cooling equipment for hot isostatic presses, specifically relating to a one-way valve cooling device for a gas compressor of a hot isostatic press. Background Technology
[0002] A hot isostatic press (HIP) is an advanced piece of equipment used in hot isostatic pressing (HIP) processes. It integrates mechanical, electrical, hydraulic, and thermal engineering disciplines, operating within a sealed container using nitrogen (or argon) as the pressure transmission medium. Under high temperature and high pressure (or ultra-high temperature and ultra-high pressure), the processed product is sintered, pressed, or densified. HIPs are primarily used for densification and forming of high-temperature materials, special ceramics, composite materials, and small to medium-sized parts. Since the operating pressure of a HIP is typically around 200 MPa, a gas compressor is required to output high-pressure gas at 200 MPa. However, the gas heats up during compression, especially at the high-pressure gas outlet near the check valve, where the temperature is even higher. Therefore, to protect the lifespan of the gas compressor's check valve and reduce the temperature of the high-pressure gas, the check valve needs to be cooled during compressor operation. Utility Model Content
[0003] The purpose of this invention is to provide a cooling device for a one-way valve in a hot isostatic press gas compressor, which aims to efficiently cool the interior of the one-way valve body.
[0004] This utility model is mainly achieved through the following technical solutions: A one-way valve cooling device for a hot isostatic press gas compressor includes a housing. A one-way valve body is disposed inside the housing. A transition cooling chamber is disposed on one side of the one-way valve body and the housing. Inlet cooling chambers and outlet cooling chambers, separated from each other, are respectively disposed at the upper and lower ends of the one-way valve body and the housing. Several sets of inlet and return water channels are disposed in the middle of the one-way valve body. The inlet cooling chamber is connected to the inlet water channels, and the inlet water channels are connected to the return water channels through the transition cooling chamber. The return water channels are connected to the outlet cooling chambers. The inlet cooling chambers and outlet cooling chambers are respectively connected to a cooling water inlet and a cooling water outlet.
[0005] To better realize this utility model, the housing further includes a first cover plate and a second cover plate, and the first cover plate and the second cover plate are respectively provided on both sides of the one-way valve body; a transition cooling cavity is provided between one side of the one-way valve body and the first cover plate; an outlet cooling cavity and an inlet cooling cavity are respectively provided at the upper and lower ends between the other side of the one-way valve body and the second cover plate, and the outlet cooling cavity and the inlet cooling cavity are separated.
[0006] To better realize this utility model, the two sides of the one-way valve body are further sealed to the first cover plate and the second cover plate by the first gasket and the second gasket, respectively.
[0007] To better realize this utility model, the second cover plate is further provided with a cooling water outlet and a cooling water inlet at its upper and lower ends, respectively.
[0008] To better realize this utility model, the transition cooling chamber, the inlet cooling chamber and the outlet cooling chamber are respectively arranged along the Y direction of the one-way valve body, and the inlet flow channel and the return flow channel are respectively arranged along the X direction of the one-way valve body.
[0009] To better realize this utility model, it is further characterized in that a set of inlet channels and return channels are respectively provided on both sides of the middle part of the one-way valve body; a first return channel and a first inlet channel are arranged sequentially from top to bottom on one side of the one-way valve body, and a second return channel and a second inlet channel are arranged sequentially from top to bottom on the other side of the one-way valve body.
[0010] To better realize this utility model, the diameters of the first return water channel and the first inlet water channel are respectively larger than the diameters of the second return water channel and the second inlet water channel; the length of the transition cooling cavity is respectively larger than the lengths of the inlet cooling cavity and the outlet cooling cavity.
[0011] The beneficial effects of this utility model are as follows: This invention features several sets of inlet and outlet water channels in the middle of the one-way valve body, all of which pass through the center of the valve body. This ensures more thorough and effective contact between the entire valve body and the cooling water, improving cooling speed and uniformity. Specifically, the invention has a simple structure. It connects cooling chambers on both sides of the cooling channels on the one-way valve body in series. Through the structural design of these cooling chambers, the axial cooling area of the one-way valve body is increased, slowing the flow rate of the cooling liquid within the channels. This effectively extends the residence time and cooling area of the cooling liquid, significantly improving the cooling effect and demonstrating good practicality. Attached Figure Description

Detailed Implementation
[0014] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] Example 1: A one-way valve cooling device for a hot isostatic press gas compressor includes a housing. A one-way valve body 1 is disposed inside the housing. A transition cooling chamber 5 is disposed on one side of the one-way valve body 1 and the housing. Water inlet cooling chambers 15 and water outlet cooling chambers 12 are respectively disposed at the upper and lower ends of the one-way valve body 1 and the housing. Several sets of water inlet channels and water return channels are disposed in the middle of the one-way valve body 1. The water inlet cooling chambers 15 are connected to the water inlet channels, and the water inlet channels are connected to the water return channels through the transition cooling chamber 5. The water return channels are connected to the water outlet cooling chambers 12. The water inlet cooling chambers 15 and 12 are respectively connected to a cooling water inlet 11 and a cooling water outlet 8.
[0018] In use, cooling water enters the inlet cooling chamber 15 through the cooling water inlet 11, passes through several inlet channels to reach the transition cooling chamber 5, and fully cools the one-way valve body 1 axially. Then, it passes through several return channels to reach the outlet cooling chamber 12, and finally flows out from the cooling water outlet 8. The transition cooling chambers 5 on both sides, the inlet cooling chamber 15, and the outlet cooling chamber 12 are used to cool the area around the one-way valve body 1, and the interior of the one-way valve body 1 is rapidly cooled through several sets of inlet and return channels.
[0019] This invention features several sets of inlet and outlet water channels in the middle of the one-way valve body 1, all of which pass through the center of the valve body 1. This ensures more thorough and effective contact between the entire one-way valve body 1 and the cooling water, improving cooling speed and uniformity. Specifically, this invention has a simple structure. It connects cooling chambers on both sides of the cooling channels on the one-way valve body 1 in series. Through the structural design of these cooling chambers, the axial cooling area of the one-way valve body 1 is increased, slowing down the flow rate of the cooling liquid inside the channels. This effectively extends the residence time and cooling area of the cooling liquid, significantly improving the cooling effect and demonstrating good practicality.
[0020] Example 2: A one-way valve cooling device for a hot isostatic press gas compressor, such as Figures 1-3 As shown, it includes a one-way valve body 1, a screw 2, a first cover plate 3, a first gasket 4, a transition cooling chamber 5, a second cover plate 6, a second gasket 7, a cooling water outlet 8, a first return water channel 9, a first inlet water channel 10, a cooling water inlet 11, an outlet cooling chamber 12, a second return water channel 13, a second inlet water channel 14, and an inlet cooling chamber 15.
[0021] The one-way valve body 1 has a first cover plate 3 and a second cover plate 6 on both sides. A transition cooling chamber 5 is provided between one side of the one-way valve body 1 and the first cover plate 3. A water outlet cooling chamber 12 and a water inlet cooling chamber 15 are provided at the upper and lower ends between the other side of the one-way valve body 1 and the second cover plate 6, respectively. A first return water channel 14 and a first inlet water channel 10 are provided sequentially from top to bottom on one side of the one-way valve body. A second return water channel 13 and a second inlet water channel 14 are provided sequentially from top to bottom on the other side of the one-way valve body.
[0022] The outlet cooling chamber 12 and the inlet cooling chamber 15 are separated to form a cooling water inlet and outlet chamber. Cooling water enters the inlet cooling chamber 15 from the cooling water inlet 11, passes through the first inlet channel 10 and the second inlet channel 14 to reach the transition cooling chamber 5, and then passes through the first return channel 9 and the second return channel 13 to reach the outlet cooling chamber 12. The first inlet channel 10, the first return channel 9, the second inlet channel 14, and the second return channel 13 can cool the center of the one-way valve body 1, resulting in better cooling effect. The volume of the outlet cooling chamber 12 and the inlet cooling chamber 15 can be increased according to cooling requirements. The number of channels on the one-way valve body 1 can be determined according to the actual cooling needs and the structure of the one-way valve body itself. A multi-channel design can make the cooling effect better and more uniform. In summary, the cooling area of the entire one-way valve body 1 includes an outlet cooling chamber 12 and an inlet cooling chamber 15, a first inlet water channel 10, a first return water channel 9 and a second inlet water channel 14, a second return water channel 13 and a transition cooling chamber 5.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
