Blasting experiment device for injection hose assembly of wheeled fire extinguisher

Abstract

The invention belongs to the technical field of product detection and particularly relates to a blasting experiment device for an injection hose assembly of a wheeled fire extinguisher. The blasting experiment device comprises an explosion-proof chamber, a worktable, a water pressurizing mechanism, a display PLC (Programmable Logic Controller) and a warmer. The blasting experiment device is characterized in that a table type worktable is arranged inside the explosion-proof chamber; a sample clamping and fixing structure of the injection hose assembly of the wheeled fire extinguisher is arranged on the worktable; the water pressurizing mechanism is communicated with a fire extinguisher head of a sample; a water sensor and an injection valve switch spanner opening / closing mechanism are arranged at the injection barrel end of the sample; the warmer and an air conditioner which are used for adjusting the indoor temperature as well as an indoor temperature sensor for detecting the indoor temperature are also arranged in the explosion-proof chamber. The blasting experiment device disclosed by the invention has the beneficial effects that the operation by persons is reduced; the degree of automation is high; the accuracy of detection results is improved, the reliability is improved, and body health of an operator is protected.

Description

technical field [0001] The invention belongs to the technical field of product testing, and in particular relates to a blasting experiment device for a spray hose assembly of a cart-type fire extinguisher. Background technique [0002] Cart-type fire extinguishers are commonly used fire extinguishing equipment and play a vital role in fire extinguishing operations. The cart-type fire extinguisher is equipped with a spray hose, the length of which is not less than 4m, and a spray control valve is installed at the end of the spray hose to facilitate intermittent spray operation and interrupt the spray of fire extinguishing agent at any time. The connection between the injection hose and the injection control valve should be reliable, and the requirements for use should be met within the operating temperature range. The injection hose assembly should be subjected to a burst test at (20±5)°C, and its burst pressure should not be less than the working pressure of the cart-type fi...
