Stage 1: When pressing and testing the water, is the heating valve open or close?
There is a centralized heating area in the north, and before heating, it is required to conduct a suppression and test water.
There are many areas, and they started to test the waters in early October, and some places began to test the waters in early September. It depends on the requirements of the local heating department.
For the heating at home, whether it is floor heating or radiator , when pressing and testing the water, everyone should follow the following requirements.
①. Do not open the valve when the pressure test starts
. At the beginning, do not open the heating valve entering the house, that is, the water supply valve and the return valve in the pipeline well.
At this time, try to fill the main pipe for supply and return water supply as much as possible. Let the heating water in the main pipe circulate back and forth. The purpose of this is to allow to circulate water and to take away the impurities precipitated in the pipe and rust.
Because the pressure test requires the pipe to be filled with water and then raised to the required pressure, for example to 0.6 kg.
After the pressure is stabilized, some impurities in the riser will slowly settle to the bottom.
②. Open the valve when the pressure is stable
How to determine the pressure stability? You can consult the duration of the pressure. , for example, it takes one day, or two days, which is different.
If the pressure test is only one day, it is recommended that you open the main heating valve at home in the afternoon.
If the pressure test is two days, I personally recommend that you open the main valve of the heating entering our house the next morning or afternoon.
The specific operation of opening the valve is also very simple.
We want to find the main pipe that enters the water supply and return water in the pipeline well, and then find two valves on it.
If it is a valve with wheels, we rotate it counterclockwise to the head. If it is with a handle, move the handle to the same direction as the water pipe.
③, Close the valve when the pressure is over
After the pressure trial is over, the water in the pipeline is in a state of pressure maintenance.
In other words, most heating companies will not leak out the water in the heating pipeline after being suppressed. In this way, the heating pipes are full of water.
After we confirm that there is no leakage in the floor heating or radiator at home, close the valves on the water supply pipes and return pipes that enter our home.
The specific operation of closing the valve is the opposite of our operation of opening the valve. For example, there is a handwheel, which rotates counterclockwise to the bottom; if there is a handle, it will move the handle perpendicular to the heating pipe.
The purpose of doing this is to ensure that the heating or floor heating in our home is in a stable state. Separated from the water phase in outdoor piping systems.
Phase 2: Formal heating, is the valve open or closed?
For centralized heating in the north, the heating time is different according to different areas. For example, in North China, most of the heating starts in mid-November.
So, we should all pay attention to the specific heating time. Then, according to the heating time, open or close the valve.
For the initial stage of heating and to the formal heating stage, I also specially consulted the heating master and gave the following operating suggestions.
①, early stage of heating
The so-called early stage of heating. It was the first few days when heating was started. For example, the heating starts on November 15th, so on November 15th and the following week are called the early stage of heating.
In the early stage of heating, I personally recommend everyone, and it is also recommended by the heating master, do not open the main valve at home. That is, the valves on the water supply and return pipes in the heating well should not be opened.
The reason why this suggests is mainly to consider the following issues:
First, in the early stage of heating, since the supply and return water began to circulate in the pipeline network, the impurities precipitated during this year began to circulate, so at this time, there were more impurities in the pipeline network.
Second, at the beginning of the cycle, impurities will enter the end. Like our home, we may enter radiators or floor heating. , and some of these impurities may be present in radiators or floor heating and cannot be taken away by the circulating masonry.
Third, the final result is that the filters in our home are seriously blocked. Another situation of is that there is no filter, and impurities may enter our radiator or floor heating, causing blockage of radiator or floor heating.
So, during the early stage of heating, if it is not necessary, you can not open the heating valve. Let the heating supply and return water circulate in the main pipe for a few days so that the impurities can be taken away as much as possible.
②, formal heating stage
The so-called formal heating stage is that after one week of heating trial operation, formal heating is basically carried out.
At this stage of formal heating, I personally recommend that you open the valve and conduct formal heating of our indoors. But pay attention to relevant operations.
One is to open the main valve to enter the house. This is what we want to open the pipeline well ourselves, find the total valve on the water supply and return water that enters our indoors, and then open it.
Second, we must observe the indoor conditions in a timely manner. focuses on checking whether there is any leakage. Because there are still differences between hot water and cold water. If you don’t leak when cold water, you may leak when hot water. So check for leakage.
Third, after there is no leakage, open the water supply and return water valves to the maximum, and then formally provide heating. so that the heating in our home will start to operate officially.
Fourth, it takes about a week to run the heating at home. It is recommended that you clean the filter once. of course, the premise is that we can clean it up by ourselves or find someone to clean it up. Because during this period of operation, many impurities may enter the filter.
It was not until the official operation was officially started and the filter was cleaned up, and the heating in our home was officially started.
Follow the above steps to basically ensure that the heating effect in our home is improved. Everyone thinks that heating at home is not effective, so you can follow these steps.
is written at the end of the article
Every time the heating season comes, everyone will find a problem, that is, some families are hot, while some families are not.
In fact, the reason for this problem is that many people do not take effective measures to deal with it in the early stage of heating. So in this article, I have shared the specific steps with you, and I hope everyone can understand it.
