Abstract

The invention relates to a fixture which is used on a filter material test desk. The fixture comprises an upstream sampling port, a downstream sampling port, an upstream airflow port, a fixture sealing port and a filter material. The fixture is characterized in that the fixture sealing port is arranged at two ends of the fixture and the fixture sealing port comprises a fixture sealing surface, a plurality of sealing lines are arranged on the fixture sealing surface, the upstream sampling port is arranged on the upper end of the fixture, the downstream sampling port is arranged at the lower end of the fixture, the filter material is arranged in the middle part of a fixture cavity, and the upstream airflow port is arranged at the other upper end part of the fixture.

Description

【Technical field】 [0001] The invention relates to a fixture, in particular to a fixture for testing filter materials. 【Background technique】 [0002] In the prior art, it is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. Also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamp...
