Product Description

Working principle

Vapor-liquid two-phase flow level regulator collects steam signal or liquid phase signal directly into the valve chamber according to the level level, and flows through the specific design of the throat after mixing with the drain. When the liquid level rises, the steam signal decreases, so the drainage flow increases; When the liquid level drops, the steam signal increases, reducing the effective throat flow area, and the drainage flow decreases, so as to effectively hinder the purpose of drainage. Based on the principle of "vapor-liquid two-phase flow", the shortcomings of traditional float ball, gas and electric type liquid level control equipment are abandoned, and the flow of liquid at the outlet of the container is automatically adjusted without energy consumption. When the water level in the heater rises, the water level in the signal tube correspondingly rises, resulting in the flow area of the sending steam body decreases, the flow of the vapor phase in the regulation pipeline decreases, and the flow of the liquid phase increases, resulting in the control valve throat steam flow area decreases, the effective flow area of the drainage increases, so that the drainage volume continues to increase, and finally the balance is established on the new drainage level height, and vice versa. Vapor-liquid two-phase flow device

Introduction

Its superior performance, advanced technology, excellent quality, accurate and maintenance-free water level control, low cost, is the preferred product to replace the traditional liquid level device. It can also be used in electric power, chemical industry, petroleum, printing and dyeing, iron and steel metallurgy and other industrial and mining enterprises, it is a new structure of equipment widely promoted in recent years.

Advantages

The new vapor-liquid two-phase flow regulator has the advantages of self-regulation, no energy consumption, accuracy, proper and free sensing, strong economy, minimal error rate, no need to overhaul, long life and so on.

Construction

The vapor-liquid two-phase flow device is composed of a sensing signal tube and a regulator. The regulator is composed of a shell, a connecting flange and a gradually shrinking and expanding spool. The central part is to regulate the steam inlet and its function is to control the size of the water drain.

Advantages

1, vapor-liquid two-phase flow device, with: self-regulation, no energy consumption, accuracy, proper sensing freely, strong economy, minimal error rate, no need to repair, long life and other advantages.
2, vapor-liquid two-phase flow device, the product without any moving parts, no mechanical and electrical transmission device, good reliability, free from external interference, strong anti-interference ability, high safety performance.
3, vapor-liquid two-phase flow device, vapor-liquid two-phase flow can achieve automatic continuous regulation, self-regulation ability is strong, the liquid level is relatively stable, no external force drive. The spool is made of high-quality stainless steel material, which is corrosion-resistant at high temperature, and can meet the long-term operation of the equipment. Once installed, there is basically no maintenance.
