There are many kinds of tank truck valves, and the common ones include explosion-proof manhole assembly, safety valve, breather valve and the like. According to the Periodic Inspection Rules for Road Transport Liquid Dangerous Goods Tank Vehicles with Metal Atmospheric Pressure Tank Body, the metal tank body carrying liquid dangerous goods needs to be periodically inspected according to the fixed inspection period. In addition to the routine inspection of the tank body itself, the most important thing is to perform functional and qualified testing on the various valves of the tank body, and the tank truck can continue to transport goods on the road only after the professional institutions and personnel have inspected and qualified and issued a certificate. The functional and qualified testing on the various valves of the tank body includes disassembly and re-inspection of the tank valves, such as sealing inspection of the explosion-proof manhole, pressure inspection of the safety valve, pressure inspection of the breather valve, etc. When performing inspection on the corresponding valves, various valves need to be removed and installed on the multiple devices of the special inspection institute for inspection. However, during actual detection, firstly, the tank truck needs to be sent to the special inspection institute, which is relatively cumbersome, especially when there are many vehicles to be inspected or when the distance to the special inspection institute is far, the process is time-consuming and laborious. Secondly, the valve inspection equipment of the special inspection institute needs to be compatible with various types of valves, so it is mostly fixed or has a large size. Therefore, even if the disassembled valves need to be sent to different departments for inspection at the special inspection institute, there is still some inconvenience. Therefore, the existing tank valve inspection is not convenient, has low inspection efficiency and poor practicality. Based on this, the utility model provides a multifunctional test bench for tank valve. UTILITY MODEL CONTENTS

[0022] like Figures 1-4 As shown, a multifunctional test bench for tank valves includes a main body 1. The main body 1 is equipped with a breather valve detection mechanism 2, a safety valve detection mechanism 3, and an explosion-proof manhole detection mechanism 4. The main body 1 is also equipped with a pressure detection device 5 that connects the breather valve detection mechanism 2, the safety valve detection mechanism 3, and the explosion-proof manhole detection mechanism 4. The pressure detection device 5 is connected to an operating device 6.

[0023] The breathing valve testing mechanism 2 includes a base 201, an L-shaped bracket 202 mounted on the upper end of the base 201, a rotating bearing 203 mounted on the end of the L-shaped bracket 202, and a breathing valve gas tank 204 mounted on the rotating end of the rotating bearing 203. The breathing valve gas tank 204 is connected to a pressure testing device 5 via a pipeline. During breathing valve testing, the breathing valve is first installed in the breathing valve gas tank 204. Then, the pressure testing device 5, activated by the operating device 6, vents air into the breathing valve gas tank 204 to test the opening pressure of the breathing valve. After the test, the breathing valve gas tank 204 can be flipped to tilt the breathing valve, thereby testing the breathing valve's anti-tipping leakage function.

[0024] The safety valve testing mechanism 3 includes a testing base 301, on which a positioning base 303 is mounted at the center of its upper end. The positioning base 303 is connected to the pressure testing device 5 via piping. Several rotary cylinders 302 are distributed around the outer circumference of the positioning base 303. A clamping block 304 is mounted on the output end of each rotary cylinder 302. The rotary cylinders 302 and the clamping block 304 together form installation fixture one, used to fix the flange-mounted safety valve 7. An internal thread is formed on the inner wall of the positioning base 303, forming installation fixture two, used to fix the threaded safety valve 7. When inspecting safety valve 7, installation fixture one and installation fixture two can be selected according to the thread and flange connection type of the safety valve 7 being tested. Then, the flange safety valve is placed on installation fixture one, and several rotary cylinders 302 are operated to tighten the flange of safety valve 7. Then, the pressure testing device 5 is vented to safety valve 7 under the activation of operating device 6 to start testing the opening pressure of safety valve 7. Threaded safety valve 7 can be directly threaded onto installation fixture two, and the pressure testing device 5 is vented to safety valve 7 under the activation of operating device 6 to start testing the opening pressure of safety valve 7.

[0025] The explosion-proof manhole inspection mechanism 4 includes a mounting base 401, which is connected to the pressure testing device 5 via a pipeline. The mounting base 401 is installed in a groove in the main body 1, and the groove is connected to a water tank via a water pipe for water lifting during airtightness testing. Several clamping cylinders 402 are circumferentially distributed along the outer edge of the mounting base 401. Clamping components 403 are installed at the working ends of the clamping cylinders 402 for fixing the explosion-proof manhole 8. During the inspection of the explosion-proof manhole 8, the manhole 8 is first placed on the mounting base 401. Then, the clamping cylinders 402 are activated, driving the clamping components 403 to press the manhole 8 tightly. Next, water from the water tank is filled into the groove, submerging the manhole 8. Finally, the pressure testing device 5, activated by the operating device 6, vents air into the explosion-proof manhole 8 to perform an airtightness test.
