Is it okay to open the exhaust valve to discharge water without closing the floor heating inlet pipe

No way. After the return pipe of the floor heating system is turned off, the water in the floor heating pipeline cannot be circulated normally, and the exhaust valve can only be used to discharge the air, and the continuous circulation of hot water cannot be realized, and the floor heating system pipeline has no heating effect. If the air in the floor heating is not clean, you need to close the return valve and open the air release valve at the same time.

The part of the main floor heating pipe entrance main pipe connected with the water separator.

The main pipeline generally uses aluminum-plastic composite pipes that need to be insulated, because this section of the pipeline often increases the heat loss in transit, which is easy to oxidize the pipeline; In underfloor heating systems with smaller units; The supervisor uses very little, and the direction is simple. However, in the larger floor heating systems such as villas or duplexes, a large amount of supervisors requires a professional designer to design the direction of the supervisor, and the installation requirements of the supervisor are also relatively strict, horizontal and vertical.

No. The user needs to open the air release valve on the water inlet pipe of the water separator, and the floor heating cannot be released during the operation. If the water in the system is to be drained, it must be without underfloor heating.

Close all valves, leaving only the water supply valve open. The valve is open when it is parallel to the direction of the pipeline, and it is closed when it is perpendicular to the direction of the pipeline. Remember the direction that is with which the valve is located in the pipe.

The branch valve is subject to the branch road, and the pipeline valve is subject to the pipeline where it is located. Unscrew the deflation valve on the water supply pipe of the separator and perform the first deflation. Until the water flow no longer contains large bubbles, becomes a water column, and then closes.

If the air in the floor heating is not clean, you need to close the return valve and open the air release valve at the same time. Floor heating main pipe, main entrance main pipe and water separator.

For the connected part, the main pipeline is generally made of aluminum-plastic composite pipe, which needs to be insulated, because this section of the pipeline often increases the heat loss in transit, which is easy to oxidize the pipeline; In underfloor heating systems with smaller units;

The supervisor uses very little, and the direction is simple. However, in the larger floor heating systems such as villas or duplexes, a large amount of supervisors requires a professional designer to design the direction of the supervisor, and the installation requirements of the supervisor are also relatively strict, horizontal and vertical.

It is also OK to vent floor heating without closing the main valve of water inlet and outlet, but the effect is not as good as closing the main valve of water outlet, but the main valve of water inlet and outlet cannot be fully closed, so that there is no pressure in the radiator, and the air cannot be discharged; Let's learn about the detailed steps of floor heating exhaust:

First of all, when deflating, you should first find the air release valve, which is generally on the water collector, at the other end of the inlet and outlet pipe interface, there is a thin copper pipe on it, and there is a round handle on it, which is the air release valve;

Second, find a hose with one end connected to the outlet of the release valve and the other end inserted into the sewer;

Then, gently rotate the round handle counterclockwise with your hand and listen for a squeaky sound to stop;

Finally, when you see a steady stream of heating water flowing out, turn the handle clockwise and close the air release valve to complete the air deflation.

In short, when we deflate, we must pay attention to safety; The water outlet must be connected with a hose to prevent the heating water from splashing out and scalding us when deflated; In addition, in central heating, due to the high water pressure, if the hose is not connected, opening the air release valve will splash the heating water far away, causing unnecessary damage to the walls and floors.

It is better to install it on the return pipe.

Press on the water inlet pipe, if the circulating water has gas, it will be backwater, referring to the high fire. That's not scientific! If there is a circulating pump on the furnace.

Circulating pumps. and pipes have little impact. It's best to have an exhaust valve, and the saddle you buy must be matched with the saddle, not bad for a few dollars, right?

It's still good to have an exhaust valve!

Summary. Dear, hello, the floor heating exhaust water is put into the water valve, the water is actually the air release, at this time you need to open the water inlet pipe, and the exhaust valve should also be opened. The gas inside is expelled first, and then the water comes out.

In general, after each heating operation, the water needs to be drained.

Dear, hello, the floor heating exhaust water is put into the water valve, the water is actually the air release, at this time you need to open the water inlet pipe, and the exhaust valve should also be opened. The gas from the vertical object inside is exhausted first, and then the water comes out. Under normal circumstances, after each heating is over, the water in it needs to be cleaned.

Open the door of the Zhongnian water supply valve, and the valve is in a parallel state, which means that it is open, and if it is perpendicular to the pipeline, it means that it is closed. Next, unscrew the exhaust valve on the water separator until there is water flowing out of it, and there are no large number of bubbles, and then sell Bi Sleepy to close the water inlet valve. According to the same method, the exhaust valves on all the geothermal pipes should be opened in turn, and all the gas in the pipes should be drained, indicating that the water in the floor heating pipes has been discharged.

Underfloor heating water separator.

There is no small valve in the upper return branch, and the main return pipe.

There is no valve, which means that the exhaust is discharged with the water from the floor heating. Floor heating water separator is the control center of the whole indoor geothermal heating, it has the function of diversion and pressure distribution, when the heat medium flows into the room, after the multi-functional filter enters the water separator this debate combustion main bar, this link filter filters out the impurities in the heat medium to prevent the impurities from entering the underground pipe network to block the pipeline.

The main bar is installed horizontally, so that the heat medium is evenly distributed to the branch pipes by using the principle of equal pressure at the same height, and after the heat exchange system, each branch pipeline flows back to the main bar for water collection, and then flows into the heating system from the return port. In addition, there is a water mixing device in the self-heating, that is to say, after the heat exchange, the temperature of the heat medium (water) is still very high, and after the water mixing system, it flows into the main bar of the water separator to continue circulation, so that energy can be saved while heating.

The floor heating inlet pipe is exhausted with regret wisdom.

It has to be vented. If there is air in the pipe, it will hinder the circulation and cause the problem of not heating, affecting comfort, and wasting energy, so the air release valve of the water inlet pipe must be opened before the geothermal use to discharge the excess air inside. It is advisable to contact a professional for exhausting.

Introduction

1. Floor heating contains a large amount of air, and air will enter the pipeline when used for a long time, which will affect the hot water circulation and reduce the heating capacity. In addition, oxygen can also corrode pipes, so it is necessary to schedule the drainage.

2. In winter, prevent the pipeline from freezing and freezing in cold weather, resulting in low water in the pipeline, and heating expansion and squeezing the pipeline, which may lead to the rupture of the pipeline, so do not turn on the floor heating in winter, remember to discharge the water in the floor heating pipe in time.

3. Avoid blockage after the heating period, if the heating is not drained in time, it is easy to form scale and block the pipeline, which will affect the heating effect in the future.

Summary. Hello! Dear, I'm glad to answer for you!

Hello, the floor heating inlet valve and the return valve are all closed, if the main pipeline of the inlet and return valves are closed, the release valve has water, that is the pipeline, there is a flow of gas, a long time has not been discharged, open the air valve, there will be water out, until the gas is discharged, there is water out.

Hello! Dear, I'm glad to answer for you! Hello, the floor heating inlet valve and the backwater hall Yanzheng valve are all closed, if the main pipeline of the inlet and return valves are closed, there is water in the gas release valve, that is the pipeline, Zaoqing has the circulation of gas, there is no discharge for a long time, open the air valve, there will be water out, until the gas is discharged, there is water outflow.

If the valve is not closed tightly and the water is leaking, just close it again. If there is air in the floor heating pipe, it will also cause the air release valve to leak, open the valve, and the shirt pin will exhaust the air inside. If the valve plate of the air release valve is displaced, just tap it gently to return the valve plate to its position.

After stopping the use of heating, then it is necessary to drop the temperature inside the radiator mold collapse, which will also lead to thermal expansion and contraction, if it is found that there is a leak at the pipe connection, if the situation is not very serious, you can use a towel to wrap it, if it is more serious, you must contact the relevant personnel to repair it. When the floor heating is used for a long time, it is also necessary to clean the filter screen, which is also to prevent some stains from blocking the filter screen, which will also cause the blockage of the pipeline, so that it will cause a relatively large impact in the later stage.
