Description
Technical Field
[0001] This utility model relates to the field of sensor detection technology, and in particular to a refrigerant poisoning and oil spraying test device. Background Technology
[0002] The background of the emergence of refrigerant monitoring systems is mainly due to the increasing demand for refrigerants in terms of energy efficiency optimization, environmental protection and energy utilization. With the global climate change and the increasing energy shortage, people's demand for energy efficiency optimization of heating and cooling systems has increased. At the same time, environmental protection regulations have put forward stricter requirements for the use of refrigerants. This system helps to evaluate the energy efficiency of refrigeration systems by monitoring and analyzing parameters such as refrigerant flow, pressure and temperature, and promptly identify and solve potential problems.
[0003] A common type of refrigerant poisoning and oil spraying test equipment has a relatively simple structure. Its test container is usually a well-sealed barrel, and the refrigerant sensor is also installed at the bottom inside. When putting the refrigerant sensor in or out before and after the test, the barrel lid needs to be opened frequently. The barrel lid is usually equipped with components such as an exhaust pipe, which makes it very inconvenient to put the refrigerant sensor in or out, resulting in a reduced user experience. Therefore, we propose a refrigerant poisoning and oil spraying test equipment. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies. A common refrigerant poisoning and oil spraying test device has a relatively simple structure. Its test container is usually a well-sealed barrel, and the refrigerant sensor is installed at the bottom inside. When taking the refrigerant sensor out before and after the test, the barrel lid needs to be opened frequently. The barrel lid is usually equipped with components such as an exhaust pipe, which makes it very inconvenient to take out the refrigerant sensor and reduces the user experience.

[0011] As a preferred embodiment of this utility model, the drawer and the test barrel are pull-out structures, and a sealing ring is bonded to the contact point between the drawer and the test barrel.
[0012] The technical advantage of adopting the above-mentioned further solution is that, through the pull-out structure of the box and the test barrel, the box can be quickly removed from the inside of the test barrel, which facilitates the handling of the refrigerant sensor and improves ease of use.
[0013] As a preferred embodiment of this utility model, a refrigerant sensor is installed inside the fixing groove and between the two clamping pieces.
[0014] The technical effect of adopting the above-mentioned further solution is that the refrigerant and lubricating oil mixture sprayed from the atomizing nozzle can be monitored and analyzed through the refrigerant sensor, thereby achieving the monitoring purpose.
[0015] As a preferred embodiment of this utility model, a lever is welded to the top of the clip.
[0016] The technical advantage of adopting the above-mentioned further solution is that by pushing the lever, the clamp can be pushed outward, thereby realizing the placement and removal of the refrigerant sensor and improving the ease of use.
[0017] As a preferred embodiment of this utility model, the top of the test barrel is threaded with a sealing cap, and an air inlet pipe and an air outlet pipe are installed sequentially from front to back on the top of the sealing cap.
[0018] The technical advantages of adopting the above-mentioned further solution are: fresh air can be introduced into the test tank through the air inlet duct, thereby diluting and detecting the mixture of refrigerant and lubricating oil; and the air inside the test tank can be discharged through the exhaust duct, which helps to improve the accuracy of the new round of monitoring work.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] In this invention, the design of the base and test chamber allows for the insertion of the refrigerant sensor into the fixing slot by pushing the lever outwards, and the clamping plate is held and fixed by the spring. This enables quick installation and fixation of the refrigerant sensor. The sensor can be sent into the test chamber by pushing the drawer, allowing it to be removed without opening the sealing cover. Compared with traditional installation methods, this greatly improves the convenience of use and effectively enhances the user experience. Attached Figure Description

[0029] Example 1
[0030] like Figure 1-3 As shown, this utility model provides a technical solution: a refrigerant poisoning and oil spraying test device, including a base 1, a test barrel 2 installed on the top of the base 1 near the left side, a control box 101 installed on the top of the base 1 near the right side, a controller 102 installed inside the control box 101, a bracket 103 welded to the top of the control box 101, a mixing tank 104 installed on the top of the bracket 103, a drawer box 201 installed on the left side near the bottom of the test barrel 2, a plurality of fixing slots 202 are equally spaced from left to right on the top of the drawer box 201 and inside the test barrel 2, clamping pieces 203 are symmetrically installed on the left and right sides inside the fixing slots 202, and springs 204 are fixedly connected between the outer side of the clamping pieces 203 and the inner wall of the fixing slots 202, a feed inlet 205 is opened on the right side of the test barrel 2, an electric valve 206 is installed inside the feed inlet 205, the electric valve 206 is electrically connected to the controller 102, and an atomizing nozzle 207 is connected to one end of the feed inlet 205 near the inside of the test barrel 2.
[0031] Example 2
[0032] like Figure 1-3As shown, the mixing tank 104 contains a mixture of refrigerant and lubricating oil. The bottom of the mixing tank 104 is connected to the inlet 205 via a hose. The refrigerant and lubricating oil mixture inside the mixing tank 104 can be transported to the inlet 205 via the hose and sprayed out through the atomizing nozzle 207. The drawer box 201 and the test barrel 2 have a pull-out structure, and a sealing ring is bonded at the contact point between the drawer box 201 and the test barrel 2. The pull-out structure of the drawer box 201 and the test barrel 2 allows the drawer box 201 to be quickly removed from the inside of the test barrel 2, facilitating the removal of the refrigerant sensor 2021 and improving ease of use. The refrigerant sensor 2021 is installed inside the fixing groove 202 and between the two clamps 203. The refrigerant sensor 2021 is electrically connected to the controller 102. The refrigerant sensor 2021 can monitor and analyze the refrigerant and lubricating oil mixture sprayed from the atomizing nozzle 207 to achieve the monitoring purpose. A lever 2031 is welded to the top of the clamp 203. By pushing the lever 2031, the clamp 203 can be pushed outward, thereby realizing the release and release of the refrigerant sensor 2021 and improving the ease of use. The top of the test barrel 2 is threadedly connected to a sealing cap 208. The top of the sealing cap 208 is sequentially equipped with an air inlet pipe 2081 and an air outlet pipe 2082. Fresh air can be introduced into the test barrel 2 through the air inlet pipe 2081 to dilute and detect the refrigerant and lubricating oil mixture. The air outlet pipe 2082 can exhaust the air inside the test barrel 2, which helps to improve the accuracy of the new round of monitoring work.
[0033] The workflow of this utility model is as follows: When installing and using the refrigerant sensor 2021 in a refrigerant poisoning and oil spraying test equipment, firstly, the drawer 201 is pulled out from the inside of the test barrel 2, and the lever 2031 is pushed outward, thereby causing the lever 2031 to move the clamping plate 203 to both sides, inserting the refrigerant sensor 2021 into the fixing slot 202. After releasing the lever 2031, the clamping plate 203 will be pushed by the spring 204 to clamp and fix the refrigerant sensor 2021. After the fixing of the refrigerant sensor 2021 is completed, the drawer 201 is pushed back into the test barrel 2 to complete the entire installation process. Compared with the traditional installation method, there is no need to frequently open the sealing cover 208, which greatly improves the convenience of use and effectively enhances the user experience.
