JBT swing air inlet valve

key word:Heat exchange element


Product description

JBT swing air inlet valve

 

1. Introduction

1.1. Purpose

JBT swing air permeable feeding valve is a supporting equipment of single pipe and multi pump pneumatic ash conveying system. It is installed on the top of bin pump and mainly controls the ventilation, feeding and conveying of bin pump.

1.2. Model meaning

JBT-200

J --- for feeding

B -- swing type

T --- with air vent

200 --- feed inlet diameter (mm)

1.3. Structural features

The valve is a valve integrating feed and air permeability. It opens the air passage while opening the feed port, so as to facilitate the loading of the bin pump. Valve plate and valve seat are made of high wear-resistant alloy. They are hard sealing mechanism with high wear resistance and long service life. The valve adopts double acting cylinder as power source, which can be opened flexibly. Because the valve plate adopts swing opening (closing) mode, and the compensation spring is installed inside the valve, so the contact between the valve plate and the valve seat is closer, and the sealing performance is good.

 

2. Main technical parameters

The main technical parameters of JBT swing type air permeable feed valve are shown in table 48-1.
