Description

Technical Field

[0001] The invention relates to the field of safety valve detection devices, and in particular to a safety valve detection device. Background Art

[0002] At present, safety valves are often used for pressure control in pressure vessels or pipelines of power plants to prevent accidents such as explosions due to excessive pressure in pressure vessels or pipelines. Safety valve inspection is generally a periodic behavior. When maintenance personnel detect that the spring of the safety valve has exceeded the safety range, it will be replaced. The current safety valve inspection requires a single safety valve to be installed on the operating table, and then an air pump is used to inflate the installed valve for inspection, which is time-consuming. Summary of the invention

[0003] In view of the above problems, the present invention proposes a safety valve detection device, which solves the defect that the existing safety valve detection requires a single safety valve to be installed on an operating table, and then an air pump is used to inflate the installed valve for detection, which is time-consuming.

[0004] The technical solution adopted by the present invention is as follows:

The semicircular grooves of the pair of fixed plates are assembled together to form a mounting hole for fixing the safety valve. A cross bar is provided at the outer end of the fixed plate, and a vertical bar is provided at the end of the cross bar. A first magnetic piece is installed on the vertical bar. The air outlet pipe is externally connected to a fixed tube, and a pair of second pistons are arranged in the fixed tube. A spring is arranged between the inner end of the fixed tube and the second piston, and a cavity between the pair of second pistons is connected to the air outlet pipe; the cavity between the inner end of the fixed tube and the second piston is a liquid storage cavity, and soapy water is stored in the liquid storage cavity. The pair of liquid storage cavities are connected by a side liquid outlet pipe, and a liquid outlet pipe is connected to the middle of the side liquid outlet pipe; the liquid storage cavities are respectively externally connected to a liquid inlet pipe, and the liquid inlet pipe is externally connected to a liquid storage tank storing soapy water, and a liquid pump is installed on the liquid inlet pipe;

[0006] A second magnetic piece is installed on the outer side of the second piston, and the opposite surfaces of the first magnetic piece and the second magnetic piece are attracted to each other. A first clip is provided on the mounting surface of one of the fixed plates, and a second clip is provided on the mounting surface of the other fixed plate, and the first clip and the second clip are used to fix a pair of fixed plates together; a rotatable rotating rod is installed between a pair of support columns at the rear end, and a plurality of spray heads are installed on the rotating rod; a branch pipe is provided in the rotating rod to connect the plurality of spray heads, and the liquid outlet pipe is connected to the branch pipe.

The existing detection device cannot confirm whether the safety valve is correctly facing the detection hole on the operating table.

Since the opposite surfaces of the first magnetic member and the second magnetic member are mutually adsorbed, the first magnetic members on the pair of vertical rods move away from each other synchronously, so that the first clip and the second clip of a pair of fixed plates are separated from each other, so that the installation valve is placed in the detection hole. The pair of second pistons move in opposite directions to each other, so that the soap water in the fixed cylinder enters the branch pipe of the rotating rod through the liquid outlet pipe, and then passes through the spray head, and the spray head sprays soap water. The sprayed soap water rebounds after the liquid gathering reflector plate and gathers on the outer surface around the safety valve, and flows downward along the outer surface of the safety valve.

[0015] (III) Beneficial effects

[0016] 1. The present invention provides multiple sets of gas injection and pressurizing mechanisms in combination with an assembly kit for fixing safety valves. The assembly kit can install and fix multiple safety valves at one time and is placed on the gas injection and pressurizing mechanisms, thereby realizing batch detection of multiple safety valves and saving detection time.

[0017] 2. In the present invention, the assembly kit can install and fix multiple safety valves at one time. It is placed on the operating table, and the installation valve on the installation hole on the assembly kit is opposite to the detection hole; the driving component drives the lifting and inflating head to move downward, and the gas flowing out of the air pump enters the lifting and inflating head connected to the pipeline built into the driving component through the air inlet pipe, and the air pressure passing through the safety valve is detected by the air pressure detection device on the operating table to judge the sealing of the installation valve.

[0018] 3. In the present invention, as the lifting and inflating head moves downward, the side rod and the piston rod are driven to move downward, so that the air pressure in the compression cylinder increases, and enters the cavity between the pair of second pistons through the side air inlet pipe, further pushing the second pistons in the fixed cylinder away from each other, and the second piston drives the second magnetic member to move. Since the opposite surfaces of the first magnetic member and the second magnetic member are mutually adsorbed, the first magnetic members on the pair of vertical rods move away from each other synchronously, so that the first clip and the second clip of the pair of fixed plates are separated from each other, so that the installation valve is placed in the detection hole. The pair of second pistons move in opposite directions to each other, so that the soapy water in the fixed cylinder enters the branch pipe of the rotating rod through the liquid outlet pipe, and then passes through the spray head, and the spray head sprays soapy water. The sprayed soapy water rebounds through the liquid gathering reflector plate and converges on the outer surface around the safety valve, and flows downward along the outer surface of the safety valve. When the safety valve is not correctly facing the detection hole on the operating table, a gap appears, and the airflow will overflow through such a gap to blow soap bubbles, and the operator can intuitively observe the generation of soap bubbles.

[0019] 4. The width of the liquid reflection plate of the present invention gradually decreases from the end close to the lateral baffle to the end away from the lateral baffle, which is conducive to the soapy water rebounding to the outer surface of the safety valve away from the spray head.
