Novel leak test valve

Abstract

The invention provides a novel leak test valve which comprises a valve body and a rotatable valve core, wherein, the valve core is arranged in the valve body; the valve body is equipped with threaded holes, exhaust vents and locating threaded holes; the first threaded hole is connected with an air compressor, the second threaded hole and the third threaded hole are respectively connected with a standard container and a container to be tested, and the fourth threaded hole and the fifth threaded hole are respectively connected with two ends of a pressure sensor; the valve body is equipped with inner circular grooves at the second threaded hole and the third threaded hole; the valve core is equipped with a pressurized shift, a pressure measurement shift, a balance shift and an exhaust shift; the circumference of the valve core is equipped with tanks along the corresponding axial positions of the shifts; a pressurized tank can enable the inner ends of the first threaded hole, the second threaded hole and the third threaded hole to be communicated together; two pressure measurement tanks can enable the inner ends of the fourth threaded hole and the fifth threaded hole to be communicated with the inner circular grooves at the corresponding sides of the threaded holes respectively; a balance tank can enable the inner ends of the fourth threaded hole and the fifth threaded hole to be communicated together; and two exhaust tanks are matched with two radial holes in a valve core and can enable the fourth threaded hole and the fifth threaded hole to be communicated with the corresponding exhaust vents respectively.

Description

technical field [0001] The invention relates to a gas leakage detection valve, which can efficiently and accurately measure the leakage situation. Background technique [0002] With the increasing complexity of products and strict requirements for safety assurance, gas leak detection technology has played an increasingly important role in production and life, especially in ensuring product quality and performance. In recent years, due to the high efficiency and practicability of leak detection technology, it has been widely used in various industries, so the requirements for corresponding leak technology are getting higher and higher, in order to be simple, fast and efficient. [0003] At present, domestic detection technologies are mainly divided into air pressure detection method, flow detection method, and inert gas detection method, but the air pressure detection method is commonly used in industry. Pneumatic detection methods are divided into direct pressure and differ...
