How Do vacuum pressure regulator Works

A vacuum regulator is a mechanism used to control and maintain the desired vacuum pressure of a vacuum system. The function of the vacuum pressure regulator is to maintain the drainage system vacuum at a preset value in response to fluctuating air intakes into the system. There are different types of vaccum control valve regulators, but the mechanical vacuum regulators discussed here work on the principle of balanced force. They are used in a variety of applications and industries such as airflow control, pressure stabilization, industrial fluid flow optimization, pump control, altitude simulation, deposit control, food packaging, fuel cell efficiency, and medical and dental equipment.


How does a vacuum regulator work?

A vacuum regulator controls pressure with inlet and outlet ports that allow higher pressure air to enter or exit a system as needed. The air flow at the outlet of the vacuum pressure regulator is at a lower pressure than the air that is introduced into the vacuum pump. When the set process vacuum pressure is reached, the vacuum regulator closes, blocking additional flow from the vacuum supply line. If the system pressure is higher than desired, the valve opens and allows air to escape. Vacuum breakers, another vacuum control device discussed later, and vacuum flow regulator works on similar principles, the main difference being that a regulator will not allow air into a system’s process line and a vacuum breaker will.

The negative pressure regulator  should be placed near or directly on the vacuum reserve tank. They have to be sensitive to react quickly to changes in the vacuum. Absolute vacuum pressure cannot go below zero, so it must be managed. It can be managed more efficiently with a vacuum regulator than with the traditional seats of a valve. The vacuum pressure regulator features a spring-loaded diaphragm mechanism that adjusts airflow from an external ambient air pump or source to better regulate internal pressure. Adjustable vacuum regulators allow the operator to ensure the system is operating at optimal pressure at all times without the need for regular manual intervention.

What types of vacuum control are there?

The two main types of vacuum controllers are digital vacuum regulators and vacuum breakers.

Vacuum regulators work by regulating the flow between the vacuum pump and the system to control the pressure level. This type is also known as a back pressure regulator because the regulated pressure is at the inlet port (back of the regulator). The vacuum pressure regulator closes to increase the absolute pressure of the system or decrease the vacuum level. Large vacuum regulators are often referred to as vacuum control valves

Another type of vacuum regulator is the vacuum breaker. It allows ambient air to enter the vacuum system to control vacuum pressure. Also called vacuum regulator. These regulators are a type of pressure reducer as the pressure is regulated via the outlet port. The regulator opens and admits more air to increase the absolute pressure of the process or decrease the vacuum level.

Vacuum breakers typically use a spring diaphragm with atmospheric pressure on top and process vacuum pressure on the bottom. The spring pulls the diaphragm up to create the preset pressure level. If the vacuum is too high, the piston pushes the valve seat down, allowing more outside air into the process. When the vacuum pressure increases to the standard level, the piston rises again, restricting the flow of incoming air.
