Feeding dome valve

key word:Heat exchange element


Product description

Feeding dome valve

 

1. Introduction

1.1. Purpose

The dome valve is the main supporting equipment of pneumatic ash conveying system. It is installed on the top of the bin pump and mainly controls the feeding and conveying of the bin pump.

1.2. Model meaning

DV- 100

DV -- Code of four top valve

100 --- feed inlet diameter (mm)

1.3. Structural features

The valve is a special valve which relies on compressed air to achieve tight sealing effect. It is suitable for handling dusty gas and abrasive bulk materials. The dome valve can pass through the static material column or the flowing material flow through the pressurized sealing, and realize the closing and sealing at the same time. The dome valve is made of wear-resistant material with excellent performance and high reliability.

 

2. Specification and performance

The specification and performance of the feed dome valve are shown in table 17-1.
