Description

Technical Field

[0001] The invention belongs to the technical field of truck gas path detection, and specifically refers to an adjustable pressure vehicle gas path simulation detector and a use method thereof. Background Art

[0002] In the field of truck transportation, the stable operation of the air system is a key factor in ensuring driving safety and vehicle performance. The truck air system is mainly composed of core components such as pumps, valves, and airbags. As the power source of the air circuit, the pump is responsible for compressing the external air and delivering it to the air system, providing continuous and stable air pressure for the entire system; the valve acts as the "traffic commander" of the air circuit, and achieves flexible adjustment of braking, suspension and other functions by precisely controlling the flow direction, flow rate and pressure of the gas; the airbag, as the execution and buffer component of the air system, assists in providing braking force when the truck brakes, and automatically adjusts the vehicle height and shock absorption effect in the suspension system according to road conditions and load. The three work together to maintain the normal operation of the truck air system.

[0003] However, the conventional barometers currently relied on for truck gas line inspections have obvious limitations. Existing barometers can only simply display the real-time air pressure value in the gas line. During the inspection process, when further adjustments to the gas line are required (such as adjusting the output pressure of the pump, changing the opening of the valve, etc.), the barometer cannot achieve independent and orderly switching of the detection and adjustment functions. This means that when inspectors are operating, it is difficult to intuitively distinguish whether the equipment is currently in the detection state or the adjustment state, which can easily cause confusion in operation. This not only reduces the efficiency of inspection, but may also cause abnormal pressure in the gas line system due to misoperation, causing safety hazards, and is difficult to meet the needs of efficient and accurate inspection and maintenance of modern truck gas line systems. Summary of the invention

[0004] In view of the above situation, in order to solve the problem that most of the existing pressure display heads and related detection equipment at the tested end have single functions and can only realize the detection function of the air pressure of the truck air circuit, and cannot independently and orderly switch to the air pressure regulation function while detecting the air pressure, the present invention provides an adjustable pressure vehicle air circuit simulation tester.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an adjustable pressure vehicle air circuit simulation tester, including a five-way pipe, a pressure display head of the measured end is installed on the side wall of the five-way pipe, an air outlet thread is installed at one end of the five-way pipe, a test tube is installed on the air outlet thread, one end of the main switch ball valve is installed at the other end of the five-way pipe, one end of the main switch ball valve is installed at the other end of the main switch ball valve, and the main air inlet joint is installed at the other end of the pressure regulating valve.

[0006] Furthermore, one end of a quick-release ball valve is installed through the top end of the outer wall of the five-way pipe, and a pressure-limiting valve is installed at the other end of the quick-release ball valve.

[0007] Further, a fine-tuning valve is installed through the bottom end of the outer side wall of the five-way pipe.

[0008] Further, an air pump is externally connected to the total air inlet joint.

[0009] This solution also discloses a usage method of the adjustable-pressure vehicle air circuit simulation detector, which mainly includes the following steps:

[0010] Step 1: Install the test pipe on the air circuit of the truck air circuit, externally connect an air pump to the total air inlet joint. At this time, close the total switch ball valve, and the pressure display meter at the measured end shows the actual air pressure of the truck air circuit at this time.

[0011] Step 2: Open the total switch ball valve, and obtain the adjusted air pressure by adjusting the pressure regulating valve; close the total switch ball valve, and the air pressure of the truck air circuit can be directly detected. Open the total switch ball valve, and the air pressure of the truck air circuit can be adjusted through the pressure regulating valve.

[0012] Step 3: Open the quick release ball valve. When the air pressure in the five-way pipe is too high, relieve the pressure through the pressure limiting valve to prevent damage to the pressure display meter at the measured end. The setting of the fine-tuning valve is used for manual pressure relief.

[0013] Adopting the above structure, the beneficial effects obtained by the present invention are as follows: The present invention provides an adjustable-pressure vehicle air circuit simulation detector, achieving the following beneficial effects:

[0014] (1) The test pipe is installed on the air circuit of the truck air circuit. When the total switch ball valve is closed, the actual air pressure of the truck air circuit can be directly and accurately displayed, facilitating the user to master the air pressure condition of the truck air circuit at any time.

[0015] (2) After opening the total switch ball valve, the air pressure of the truck air circuit can be flexibly adjusted to the required value through the pressure regulating valve. The operation is simple and can meet the diverse requirements of different scenarios for the air pressure of the truck air circuit.

[0016] (3) Closing the total switch ball valve can independently detect the air pressure, avoiding interference with the detection during the adjustment process; opening the total switch ball valve can perform air pressure adjustment, realizing independent and orderly switching between the detection and adjustment functions, and ensuring the operation stability.

[0017] (4) The quick release ball valve is set, and when the air pressure in the five-way pipe is too high, it can automatically relieve the pressure, effectively preventing damage to the pressure display meter at the measured end caused by too high air pressure, extending the service life of the equipment and reducing the maintenance cost.

[0018] (5) The fine-tuning valve provides an option for the user to manually relieve the pressure. In special cases where the automatic pressure relief mechanism fails or rapid air pressure reduction is required, manual operation can be performed to achieve rapid pressure relief, enhancing the emergency handling ability and operation flexibility of the device.

[0026] As Figures 1-3 shown, the present invention proposes an adjustable pressure vehicle air circuit simulation detector, including a five-way pipe 8. One end of the quick release ball valve 2 is installed through the top end of the outer side wall of the five-way pipe 8, and the pressure limiting valve 1 is installed at the other end of the quick release ball valve 2. One end of the fine tuning valve 7 is installed through the bottom end of the outer side wall of the five-way pipe 8.

One end of the five-way pipe 8 is installed with an outlet stud 4, and a test pipe 9 is installed on the outlet stud 4. One end of the main switch ball valve 3 is installed at the other end of the five-way pipe 8, and one end of the pressure regulating valve 6 is installed at the other end of the main switch ball valve 3. The other end of the pressure regulating valve 6 is installed with a main air inlet joint 10, and the main air inlet joint 10 is externally connected to an air pump.

[0027] During actual use, the test tube 9 is installed on the air circuit of the truck. The total intake joint 10 is externally connected to an air pump. At this time, the main switch ball valve 3 is closed, and the pressure display meter head 5 at the measured end shows the actual air pressure of the truck air circuit at this time. When the main switch ball valve 3 is opened, the required adjusted air pressure can be obtained by adjusting the pressure regulating valve 6; when the main switch ball valve 3 is closed, the air pressure of the truck air circuit can be directly detected. When the main switch ball valve 3 is opened, the air pressure of the truck air circuit can be adjusted through the pressure regulating valve 6. When the quick release ball valve 2 is opened, when the air pressure in the five-way pipe 8 is too high, the pressure is relieved through the pressure limiting valve 1 to prevent damage to the pressure display meter head 5 at the measured end. The setting of the fine adjustment valve 7 is used for manual pressure relief. The above is the overall working process of the present invention. Just repeat this step the next time it is used.
