Hard seal safety valve detection equipment

Abstract

The invention discloses hard seal safety valve detection equipment. The equipment comprises a base, the top of the base is fixedly connected with a pressurizing device, a pressurizing container and adetection pipe, the top of the pressurizing container is fixedly connected with an outer butt joint opening, the top of the outer butt joint opening is fixedly connected with a safety valve body, anda pressure relief opening is formed in the right side of the safety valve body. A guide pipe is arranged in the pressure relief opening, a piston is arranged in the detection pipe, a push rod extending out of the detection pipe is fixedly connected to the top of the piston, a connecting plate is fixedly connected to the top of the push rod, a fixing block is fixedly connected to the left side of the connecting plate, and a gear is arranged in the fixing block; and the front face of the gear is fixedly connected with a rotating shaft, and the outer side of the rotating shaft is fixedly connected with a rotating disc. The hard seal safety valve detection equipment is convenient to operate, can visually judge whether the air tightness of the safety valve reaches the standard or not, and improves the safety valve air tightness detection efficiency.

Description

technical field [0001] The invention relates to the technical field of safety valve testing equipment, in particular to a hard-sealed safety valve testing equipment. Background technique [0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . [0003] When the safety valve is tested for tightness, two detection methods are usually used: the bubble count method and the leakage volume detection method. The safety valve is judged by manually counting the number of bubbles generated within one minute or calculating the volume of gas leaked within one minute. Whether the airtightness of the safety valve is up to the standard, these two methods have disadvant...

[0003] When the safety valve is tested for tightness, two detection methods are usually used: the bubble count method and the leakage volume detection method. The safety valve is judged by manually counting the number of bubbles generated within one minute or calculating the volume of gas leaked within one minute. Whether the airtightness of the safety valve is up to the standard, these two methods have disadvantages such as inconvenient operation and low efficiency, and it is impossible to intuitively judge whether the airtightness of the safety valve is up to the standard
