Abstract
The application relates to the technical field of maintenance tools, in particular to a sealing detection device which comprises an air pipe, an air inlet connector and a pressure gauge. The air inlet connector is communicated with the air pipe, the pressure gauge is connected to the air pipe, and the pressure gauge is used for detecting air pressure in the air pipe.

Description
Technical Field
The application relates to the technical field of maintenance tools, in particular to a sealing detection device.
Background
At present, the automatic transmission vehicle type in the field of passenger vehicles in China has an increasingly high ratio, which is over 70 percent. Meanwhile, due to the change of various automatic transmission technologies, the design life of the transmission is short to a certain extent, and the failure rate is high, so that the automatic transmission maintains abnormal fire and explosion in the market. In middle and large automatic transmission maintenance enterprises, equipment and special tools are quite complete, but in some small professional maintenance factories, 4S shops and comprehensive maintenance enterprises, hardware facilities are not quite complete. For the maintenance business of the automatic transmission, some are delivered to a professional factory, and some are maintained by themselves. During actual repair, the repair rate is also relatively high. The main reason is that the sealing test of various automatic transmission terminal elements is unreliable, or a traditional compressed air test method is adopted, and the specific method is that compressed air is introduced into a fluid passage of an element to be tested, and whether the element to be tested leaks air or not is judged by whether the compressed air can drive the element to be tested to execute action. Therefore, the detection can only find out whether the element executes the action correctly, the tightness of the element to be tested cannot be tested accurately, compressed air can still drive the element to be tested to execute the action when the element to be tested leaks slightly, and the reliability of the tested tightness result is not high.

The application provides a seal detection device which comprises an air pipe, an air inlet joint and a pressure gauge. The air tube is used for communicating with the fluid passage of the element to be measured. The air inlet joint is communicated with the air pipe and is used for communicating an air source. The manometer is connected on the trachea, and the manometer is used for detecting the atmospheric pressure in the trachea. When it is necessary to seal a component, the operator communicates the air tube with the fluid path of the component to be tested. The air inlet connection is then connected to compressed air as a source of air. At this time, the compressed gas enters the gas pipe from the gas inlet joint and then is introduced into the fluid passage of the element to be tested. At this time, the manometer detects the air pressure in the air pipe in real time.

Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, based on the examples herein, which are within the scope of the utility model as defined by the claims, will be within the scope of the utility model as defined by the claims.
Hereinafter, embodiments will be described with reference to the drawings. Furthermore, the embodiments shown below do not limit the summary of the utility model described in the claims. The whole contents of the constitution shown in the following examples are not limited to the solution of the utility model described in the claims.
Referring to fig. 1, the present embodiment provides a seal detection device including an air pipe 1, an air inlet joint 2, and a pressure gauge 3. The air pipe 1 comprises a connecting pipe 11 and a three-way pipe 12, the pressure gauge 3 is connected to a first air port of the three-way pipe 12, the air inlet joint 2 is communicated with a second air port of the three-way pipe 12, and a first end of the connecting pipe 11 is connected with a third air port of the three-way pipe 12.
When it is necessary to perform a seal test on a certain component, the operator communicates the first end of the connecting tube 11 with the fluid passage of the component to be tested. The inlet fitting 2 is then connected to compressed gas as a source. At this time, compressed gas enters the gas pipe 1 from the gas inlet joint 2 and then passes into the fluid passage of the element to be tested. At this time, the pressure gauge 3 detects the air pressure in the air pipe 1 in real time.
The operator first determines whether the device to be tested generates an execution action, if the device to be tested cannot generate the execution action, the device to be tested is damaged or leaked seriously. If the execution action can be generated, then the pressure gauge 3 is observed, if the reading of the pressure gauge 3 is unchanged or the variation range is small, the sealing performance of the element to be detected is good, and if the reading of the pressure gauge 3 is greatly reduced or the fluctuation is severe, the sealing performance of the element to be detected is poor, so that the sealing performance of the element to be detected can be detected more accurately. And the pressure gauge 3 is observed to control the pressure of the compressed gas, so that the damage of the element to be tested caused by the overlarge pressure is prevented.
As an alternative embodiment, it further comprises a test connector 4, wherein the test connector 4 is connected to the second end of the connecting pipe 11, and a conical surface is arranged on the outer side of the test connector 4. When the element to be tested is subjected to sealing detection, the conical surface on the outer side of the test joint 4 is abutted against the interface of the fluid passage of the element to be tested, so that the sealing performance between the test joint 4 and the fluid passage of the element to be tested is better, and the problem that the leakage between the test joint 4 and the fluid passage of the element to be tested is serious and the influence on the detection result is larger is prevented
In some embodiments, the test connector 4 is made of rubber, so that the sealing performance between the test connector 4 and the fluid passage of the device under test is better.
As an alternative embodiment, a gas valve 5 is also included, wherein the gas valve 5 may be a roller type mechanical valve. The air outlet of the air valve 5 is connected with a second air port of the three-way pipe 12. The air inlet connector 2 is communicated with the air inlet of the air valve 5. After the compressed gas enters from the air inlet joint 2, if the air valve 5 is in an open state, the compressed gas can enter the air pipe 1 through the air valve 5, and if the air valve 5 is in a closed state, the compressed gas is blocked by the air valve 5 and cannot enter the air pipe 1.
In this way, after the air valve 5 is put in the closed state, the air inlet joint 2 can be consistently kept connected with the air source. When a certain element needs to be sealed and detected, an operator communicates the first end of the connecting pipe 11 with the fluid passage of the element to be detected, then the air valve 5 is opened, compressed air can enter the fluid passage of the element to be detected after being introduced into the air pipe 1, and the air tightness of the element to be detected is detected. After the detection is finished, the air valve 5 is placed in a closed state again.
As an alternative embodiment, a first handle 6 is also included. An air passage is provided in the first handle 6 so as to penetrate in the longitudinal direction. The first handle 6 is connected to the air inlet fitting 2 such that the air inlet fitting 2 communicates with the first end of the airway. The first handle 6 is connected to the tee 12 of the trachea 1 such that the second end of the airway is in communication with the trachea 1. So that compressed air entering the air inlet fitting 2 can flow through the airway in the first handle 6 and into the air tube 1.
When a certain element needs to be subjected to sealing detection, an operator can hold the first handle 6 to press the test connector 4 connected to the air pipe 1 at the fluid passage interface of the element to be detected, so that force application is more convenient.
As an alternative embodiment, a second handle 7 is also included. A second handle 7 is attached to the side wall of the trachea 1. When a certain element needs to be subjected to sealing detection, an operator can hold the second handle 7 to press the test connector 4 connected to the air pipe 1 at the fluid passage interface of the element to be detected, so that force application is more convenient.
In some embodiments, both the first handle 6 and the second handle 7 are attached to the side wall of the trachea 1. And the first handle 6 and the second handle 7 are respectively positioned at two sides of the trachea 1. The operator can hold first handle 6 and second handle 7 respectively with both hands, and the application of force is more even effective in the both sides of trachea 1 respectively.
As an alternative embodiment, further comprising:
The pressure regulating valve 8 and the air inlet joint 2 are communicated with the air pipe 1 through the pressure regulating valve 8.
