Multi-station air tightness detection equipment for low-temperature stop valve

Abstract

The invention discloses multi-station air tightness detection equipment for a low-temperature stop valve. The multi-station air tightness detection equipment comprises a mounting bottom plate, a placement unit, a conveying unit and a detection unit. A mounting frame is arranged in the middle of the lower surface of the mounting bottom plate, foot pads are arranged at the four corners of the bottom of the mounting frame, a mounting vertical plate is arranged on the rear side of the upper surface of the mounting bottom plate, a mounting top plate is arranged at the top of the mounting vertical plate, and three symmetrically-distributed reinforcing ribs are arranged in a vertical included angle formed by the rear side face of the mounting vertical plate and the upper surface of the mounting bottom plate. Two symmetrically-distributed guide plates are arranged in the middle of the upper surface of the mounting bottom plate, and a touch sensor is arranged at the right end of the front side face of the guide plate at the rear end. The placement unit corresponds to a sliding groove formed between the upper surface of the mounting bottom plate and the two guide plates in position. The conveying unit is arranged on the front side of the upper surface of the mounting bottom plate and corresponds to the placement unit in position. The multi-station air tightness detection equipment for the low-temperature stop valve can improve the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of air tightness detection of low temperature cut-off valves, in particular to multi-station air tightness detection equipment of low temperature cut-off valves. Background technique [0002] Air tightness testing is applied to the rigorous integrity assessment of airtight components such as aircraft, automobile casings, and valves. It is a quality control application developed for the transportation sector, military sector, and basic industries to improve the airtightness of vehicles, aircraft, and ships. Put the ultrasonic transmitter inside the container. Due to the characteristics of ultrasonic waves, these waves can penetrate small holes. Using an ultrasonic inspection system outside the container, inspectors can quickly find out the source of defects, which may become potential water leaks or wind. Noise, low temperature globe valve refers to the valve in which the closing member (disc) moves along the...

Problems solved by technology

Since the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, This type of valve is very suitable for cutting off or regulating and throttling. The low temperature globe valve needs to be tested for air tightness after the production is completed. Traditional air tightness testing equipment requires operators to put them into the equipment one by one. Observe the pressure change. Such a detection method is not convenient to find the cause of the leaking parts, and the detection efficiency is low. Therefore, in order to solve such problems, we propose a multi-station air-tightness detection equipment for low-temperature globe valves.
