Device for detecting ventilation quantity of ventilated material sample block of water feeding hole

Abstract

The invention discloses a device for detecting a ventilation quantity of a ventilated material sample block of a water feeding hole. The device comprises a detection box with an opening in one end, anupper top cover arranged in the detection box and driven by an air cylinder to move up and down, and a lower base matched with the upper top cover to form a test cavity; a partition plate for dividing an inner space of the detection box into an upper part and a lower part is arranged in the detection box; the lower base is mounted on the partition plate; a groove used for containing the ventilated material sample block is formed in the lower base; a through hole communicating with a lower space of the detection box is formed in the bottom of the groove; sealing gaskets with the sealing effects are arranged on the upper top cover and the lower base; the detection device further comprises a gas inlet mechanism used for introducing gas into the test cavity; and the upper top cover is furtherconnected with a ventilation quantity detector used for detecting the ventilation quantity of the ventilated material sample block. According to the device, the operation is simple and the sealing performance is good; the detection efficiency can be greatly improved; and the manpower and material resources are saved.

Description

technical field [0001] The invention relates to a device for detecting the air permeability of an air-permeable material sample block at an upper nozzle. Background technique [0002] At present, most of the upper water inlets are air-permeable upper water inlets, and the air flow rate needs to be tested before leaving the factory. However, the existing detection devices are cumbersome to debug during the process of connecting to the upper water inlets, and the sealing performance cannot be guaranteed, which is time-consuming and laborious. , greatly reducing the detection efficiency. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a device for detecting air flow of air-permeable material sample block at the upper nozzle. [0004] The technical solution of the present invention is: a device for detecting the air flow rate of the air-permeable material sample block at the upper nozzle, including a detection box with an o...
