Abstract

The invention discloses a multifunctional mini-resistance integrated protection device used for a fan outlet side. The device comprises a shell (1), wherein one end of the shell (1) is provided with an air inlet (2), and the other end of the shell (1) is provided with an air outlet (3). The multifunctional mini-resistance integrated protection device is characterized in that a check valve (4) is installed in the shell (1); the shell between the inner end surface (6) of the air inlet (2) and the air outlet (3) is provided with an outlet (7) shared by pressure relief and evacuation; and the outlet (7) is provided with a pressure relief and evacuation pile-up valve (8). The multifunctional mini-resistance integrated protection device simultaneously has all functions of a pressure release valve, the check valve and an unloading valve, can be independently used, has small installation land occupation and is convenient to install, installing and debugging time can be shortened, and the installation auxiliary attachments of the traditional valve are omitted.

Description

technical field [0001] The invention relates to a fan attachment, especially a fan protection device for voltage stabilization, venting, anti-backflow and noise reduction used in conjunction with a Roots blower, specifically a protection device that integrates various protection devices A micro-resistance multifunctional integrated protection device is used on the outlet side of the fan in a small casing. Background technique [0002] At present, the Roots blower system at home and abroad is mainly composed of imported air filters, imported mufflers, Roots blowers, power equipment, flexible joints, outlet mufflers, pressure relief valves, T-shaped pipes for pressure relief valves, pressure gauges, check valves, Vent electric or pneumatic butterfly valve, vent valve T-tube and vent muffler etc. [0003] The gas delivered by the Roots blower is oil-free, and its main functional part is the impeller. There are small working gaps between the impeller and the impeller, the impe...
