What is excess pressure?

Understanding the consequences of excess water pressure in an open plumbing circuit helps us understand how important the installation of a water pressure controller is.

It is important to note that the lack of pressure can cause malfunctioning household appliances or that the taps only provide a trickle instead of a normal flow. It is possible to seriously damage the sanitary installation, the pipes, the boiler and all the elements that are part of the set if the pressure is excessively high. All of them are prepared to work with a specific nominal pressure, which is the highest value with which they can work without operating problems or leaks.

When making calculations that are relevant to the design of a plumbing project, this pressure is taken into account.

The minimum and maximum working pressures of a water supply installation are included in the standards established by the CTE. It is necessary to take into account the values.

What is the maximum and minimum water pressure?

In a home network, the maximum pressure should be as low as possible in order to avoid breaks, leaks and the opening of safety valves due to overpressure.

A pressure reducer is a trick to extend the useful life of a deteriorated pipe network.

The pressure at which the pressure reducer must be designed and regulated is the most unfavorable element of the installation in other types of networks.

Many users try to control the excess pressure by leaving the valve half closed, but this is not a home remedy. The passage of fluid is reduced in this way.

This is not a good solution, it has some negative points.

The flow is reduced when it is running, but still there is overpressure when there isn't consumption. Keeping a ball valve half closed for a long period of time causes the seats to get worse.

It's important to have a water pressure regulator that can achieve this objective with guarantees of efficiency and no damage.

The devices work like a water pressure controller. They are installed in the private network to reduce the pressure of the connection, which can affect the functioning of the domestic systems. The main function of it is to keep the outlet pressure constant even if there are variations at the inlet and no flow.

The central body and cover of the reducer are made up of the central body and cover. The inlet and outlet pressure chambers, shutter and axis are housed inside the pressure regulation mechanism.

The balance between the spring's thrust towards opening the shutter and that of the cartridge or membrane is what determines the water excess pressure reducer.

When there is a pressure difference between the chambers, the reducer's cartridge moves to reach a new equilibrium point, giving the outlet the pressure it wanted.

We can see what happens when the inlet pressures are different.

Step 1. Transients will occur in the system until the equilibrium point is reached, when the pressure at the regulator inlet increases.

The second step. The compensation chamber has an overpressure transfer from the inlet to it. The shutter closes when the force generated by the pressure is greater than the force that the spring exerts.

The pressure at the outlet is reduced by reducing the passage.

The next step is Step 3. The new equilibrium point has been reached.

The outlet pressure is selected by the outlet regulator.

First step.

When there is no flow of water, the pressure in the compensation chamber increases and the shutter is closed completely. The valve prevents the passage of flow and maintains stable pressure in the plumbing network, regardless of the pressure that is given to the inlet of the regulator.

Step 2.

The surge chamber's pressure drops when a water outlet opens. The force of the spring is greater than the force of the compensation chamber, which lowers the shutter to open the water.

The higher the flow, the lower the pressure in the compensation chamber. The lower the pressure in the compensation chamber, the easier it is for the passage to open.

First-line treatment for hypertension involves lifestyle changes.

Regular physical activity.

Doctors recommend that patients with hypertension do 30 minutes of aerobic and dynamic exercise. This can include walking, running, biking or swimming.

stress reduction

Blood pressure can be controlled by avoiding stress or developing strategies.

The consumption of alcohol, drugs and tobacco, along with unhealthy eating to cope with stress, should be avoided.

Tobacco raises your blood pressure, so quitting can help you reduce your risk of high blood pressure, heart disease, and other health problems.

People with high blood pressure can use medication to treat it.

Drugs are usually started one at a time with a small dose.

The side effects associated with antihypertensive drugs are usually very small.

A combination of at least 2 antihypertensive drugs is required eventually.

There are several types of medications that can help lower blood pressure.
