Description

[0002] Engine test fluid is the liquid used when the automobile engine is tested under a certain load, power and temperature before it is assembled and shipped out of the factory. During this process, it is necessary to check whether the engine has any errors or leaks and whether it can operate normally. The engine test fluid is also needed to cool the engine during operation to ensure the normal progress of the engine test. During the engine test, the flow and temperature of the engine test fluid will be monitored by a detection device to ensure the normal cooling capacity of the engine test fluid.

[0003] However, the existing engine test fluid detection devices are mostly set at the outlet of the engine test fluid circulation pipe, and the detection structure of the engine test fluid detection device is mostly arranged in the outlet of the circulation pipe, which affects the circulation efficiency of the engine test fluid in the circulation pipe. At the same time, the temperature of the engine test fluid detection device will be reduced under the continuous flushing of the engine test fluid, and the detection of temperature by the detection device is easily distorted. In order to solve the shortcomings of the prior art, we propose an engine test fluid detection device. Utility Model Content

The ends are connected, one end of the shunt pipe 9 is connected to one end of the engine test fluid circulation pipe, and one end of the output pipe 14 is also connected to the engine test fluid circulation pipe. Then, the screw rod 4 is rotated to drive the piston 3 to move upward in the detection device body 1 through the thread. The piston 3 no longer blocks the input pipe 2. The engine test fluid enters the detection device body 1 through the input pipe 2. After the engine test fluid enters the detection device body 1, it passes through the flow monitoring probe 7. The flow monitoring probe 7 monitors the flow rate of the engine test fluid when it enters the detection device body 1 and transmits it to the flow monitor 6 for display. The detection devices are separated, which does not affect the circulation efficiency of the engine test fluid in the detection device body 1.

[0023] like Figure 1 and Figure 3 As shown, a bend pipe 8 is detachably mounted on one end of the detection device body 1, a shunt pipe 9 is detachably mounted on one end of the bend pipe 8, a second valve slot is provided on one side of the inner wall of the shunt pipe 9, a spherical block 10 is slidably connected inside the second valve slot provided on the shunt pipe 9, a through hole is provided on one side of the spherical block 10, a connecting shaft 11 is detachably mounted on the top of the spherical block 10, a second rotating shaft 12 is detachably mounted on the bottom of the spherical block 10, a turntable 13 is detachably mounted on one end of the second rotating shaft 12, and the engine test fluid passes through the detection device body 1 The engine test fluid enters the bend pipe 8 and the shunt pipe 9, and then the engine test fluid is output to the engine test fluid circulation pipe through the shunt pipe 9 for circulation, and then the turntable 13 is rotated to drive the second rotating shaft 12 to rotate, and the second rotating shaft 12 drives the spherical block 10 to rotate until the through hole in the spherical block 10 is parallel to the inner wall of the shunt pipe 9, and the engine test fluid enters the output pipe 14 through the through hole of the spherical block 10. At this time, the engine test fluid enters the shunt pipe 9 from the bend pipe 8 and then shunted. The shunting detection of the engine test fluid does not affect the circulation.

[0025] How it works

[0026] It should be noted that the utility model is an engine test fluid detection device. When in use, first connect one end of the output pipe of the engine test fluid to one end of the input pipe 2, connect one end of the shunt pipe 9 to one end of the engine test fluid circulation pipe, and connect one end of the output pipe 14 to the engine test fluid circulation pipe. Then, rotate the same turntable 13 detachably installed on the top of the first rotating shaft 5. The rotation of the same turntable 13 drives the screw rod 4 to rotate. The rotation of the screw rod 4 drives the piston 3 to move upward in the detection device body 1 through the thread. The piston 3 no longer blocks the input pipe 2. The engine test fluid enters the detection device body 1 through the input pipe 2. After the engine test fluid enters the detection device body 1, it is monitored by the flow rate. Probe 7, flow monitoring probe 7 monitors the flow rate of the engine test fluid when it enters the detection device body 1 and transmits it to the flow monitor 6 for display. Then the engine test fluid enters the bend pipe 8 and enters the shunt pipe 9 through the detection device body 1. Then the engine test fluid is output to the engine test fluid circulation pipe through the shunt pipe 9 for circulation. Then the turntable 13 is rotated to drive the second shaft 12 to rotate, and the second shaft 12 drives the spherical block 10 to rotate until the through hole in the spherical block 10 is parallel to the inner wall of the shunt pipe 9. The engine test fluid enters the output pipe 14 through the through hole of the spherical block 10. At this time, the engine test fluid enters the shunt pipe 9 from the bend pipe 8 and then shunted, thereby achieving the purpose of shunting the engine test fluid without affecting the circulation.

[0027] The pressure of the engine test fluid entering the output pipe 14 after diversion is reduced for the first time, and then the engine test fluid entering the output pipe 14 is separated and blocked by the arc structure at the first baffle plate 17 and the second baffle plate 18, and the pressure of the engine test fluid in the output pipe 14 is reduced for the second time, so that the temperature monitoring probe 16 measures the temperature of the engine test fluid after the second weakening. The temperature monitoring probe 16 monitors the temperature of the engine test fluid in the output pipe 14 and transmits it to the temperature monitor 15 for display, thereby achieving the purpose of detecting temperature under normal conditions.
