Pneumatic Conveying Solution for Breath Valves & Pressure Relief Valves

Functions

Positive Pressure Air Release： During bin pump air intake, fluidization and feeding, internal bin pressure rises; the valve automatically exhausts air to stabilize pressure.

Negative Pressure Air Intake： When discharging materials and creating negative pressure, the valve automatically supplements air to prevent bin collapse and tank deformation caused by vacuum.

Sealed Dust Prevention： Built-in dust filter layer ensures dust-free exhaust and eliminates dust leakage.

Application Scenarios

Silos & bin pumps for fly ash, mineral powder, cement powder, lime powder, grain particles, chemical powder and lithium battery powder

Air replenishment and pressure balancing for silos in negative pressure suction conveying systems

Pressure balance for dust ash silos to avoid overpressure bulging and vacuum collapse

Scheme 1: Pneumatic Conveying System with Pressure Vessel Pump

Top of pressure vessel pump: Breather valve (pressure stabilization & dust prevention)

Side/top of tank body: Spring-loaded relief valve (overpressure safety protection)

Normal startup and shutdown rely on the breather valve to balance air pressure; the relief valve provides backup protection against abnormal overpressure, delivering dual safety safeguards.

Scheme 2: Large Ash Silo / Powder Raw Material Silo

Silo top: Breather valve (positive & negative pressure balancing + dust prevention)

Backup device at silo top: Weight-loaded safety relief valve

Scheme 3: Negative Pressure Pneumatic Suction Conveying System

Top of material silo: Negative-pressure breather valve (core function: air make-up to prevent silo collapse under vacuum)

Negative pressure pipeline: Low-pressure relief valve for balancing pipeline vacuum degree
