What should I do if the floor heating exhaust valve leaks, and what is the reason why the water inle

Property, exhaust valve leakage for what floor heating. Or you didn't make it clear.

If you are looking for a property, they should have the previous construction party**, contact them to see if there is an exhaust valve of the same model, and buy one. Generally, the floor heating is done by the professional floor heating installation team recruited by the contractor, and the property is not contacted, so you can ask the developer.

Look at whether there is a manufacturer's brand or ** on the water separator, it really can't work, just look for it in the market yourself.

If the leak is more serious, then you should consider the heating, be careful that the water leaks downstairs for a long time.

solutions to underfloor heating leaks;

1) The location of the leakage point should be detected first (each loop is subjected to a pressure test, the pressure state is observed to be normal, and the loop where the leakage point is located is determined).

2) After determining the loop where the leakage point is located, check the specifications of the geothermal pipe (such as PE-RT PB pipes, which can be treated by hot melt welding (the technology is mature, PEX can be treated with copper joints.

3) The maintenance of floor heating pipes involves tools such as hot melt machines, peeling machines, and connecting pipe fittings, and the maintenance personnel must have excellent skills.

Spend some money yourself and go directly to the building materials market to find a special floor heating. Let them fix it. It is estimated that it must not be cheap.

Negotiate with the property first, and if it doesn't work, you can only consider changing it yourself.

Whoever installed the floor heating consulted whomever it was. Changing the valve is, of course, to manage the heating.

Take a picture**. There are many types of exhaust valves. Need to be sure.

This situation is mainly caused by a clogged exhaust hole, and we can shine a flashlight on this hole to see the blockage. Generally speaking, if the situation is not serious, you can just poke it with a needle for sewing clothes, and the water can be discharged from the pin burial tank. However, at this time, the fitting cannot be screwed back immediately, and its inlet valve needs to be exhausted, and it can be finished after the exhaust.

There are several reasons why the exhaust valve of floor heating return water does not come out of water, as follows:

The first is the main return pipe used.

Carry out water discharge. At this time, all the circuit branch valves are all opened, if the water cannot be released at this time, the reason is that the entire return pipeline is blocked or the valve is not opened. Because at this time, the water supply and return water in the entire pipeline are placed, if the return water does not come out, it can only mean that the valve in our home is not fully opened or the valve is damaged, because of the water collector at this time.

The heating pipe is hot, but the return pipe is cold, so the water can't come back. At this time, the key check is whether the valves of each circuit are open and damaged.

The second case is the release of backwater in a single circuit. At this time, we must first confirm that the water supply valve and the return valve of this circuit are open, if the return water can not be released at this time, then the loss of Tong means that the single circuit pipe has been blocked. At this time, the method of high-pressure flushing can be used to flush the single circuit, so that the blockage in the pipeline can be dredged to solve the situation that no water can be released in the single circuit.

How to release water if the return pipe is not hot?

First, close the return main valve (pulled perpendicular to the pipe) to prevent water from being released from the return pipe. Then, place the water separator in the home.

Only one of the liquid chains is left open, and the other is closed. Next, connect a water pipe to the return water exhaust valve, unscrew the exhaust valve, and use a small basin to connect the water flowing out of the water pipe. Finally, repeat the second step to close one of the pipelines that have been drained and open the other one. And so on until the hot water enters the underfloor heating pipes.

The reason why the floor heating exhaust valve is open and there is no water is that the pressure of the floor heating system cannot reach the state of water supply.

The solution is as follows: if the pressure of the floor heating system cannot be reached, you can contact the floor heating company in time to overhaul the pressure of the floor heating system, which can solve the problem that there is no water when the exhaust valve is opened.

The exhaust valve is usually installed at the highest point of the system, mainly because the solubility of the air in the water will gradually decrease due to the increase of water temperature, then the water will gradually separate the air in the operation of the underfloor heating system and gradually rise, and finally concentrate at the highest point of the system. Valves used to release air pockets generated in heating systems and water supply pipes are widely used in water separators and radiators. I conceal it.

Solution: 1. The exhaust valve is not tight enough.

If the heating automatic exhaust valve is leaking because the exhaust valve is not tight enough, we can simply tighten the exhaust valve.

2. The air in the exhaust pipe is not clean.

If the air in the exhaust pipe of the heating is not clean, it will also cause the automatic exhaust valve to leak, we can use the method of venting in stages, unscrew the exhaust valve, let the air slowly discharge, and then tighten it and open it again until all the air in the pipe is discharged.

3. The exhaust valve is rusty.

Because the heating has not been used for a long time, there is rust in the exhaust valve, which causes the valve to rust, so as soon as the heating is delivered, the pressure will become larger, which will cause the automatic exhaust valve to leak, we can remove the exhaust valve, clean the rust at the exhaust valve port, and solve the problem of water leakage.

4. The valve plate in the exhaust valve is displaced.

If the valve plate in the heating automatic exhaust valve is displaced, it will cause the pressure in the pipe to decrease when the exhaust valve is deflated, resulting in water leakage.

5. Aging of rubber gaskets.

If the rubber gasket inside the automatic exhaust valve is aging, it will also lead to water leakage, and we need to replace it with a new rubber gasket to solve the water leakage.

You need to close it again and tighten it with a tool. If the valve of the exhaust valve is not closed tightly enough, it may cause the exhaust valve to leak.

There is also a possibility of leakage of the exhaust valve, that is, the air in the exhaust pipe is not clean, and there is a large amount of air in the floor heating pipe, which will also cause the exhaust valve to leak. At this time, we can exhaust in stages, unscrew the valve a little, do not open it all, drain the air and screw it, and then drain it again after a while, until all the air in the pipe is discharged, and the water is discharged into the pipe, and it will be discharged, so that the exhaust valve will not leak.

Most of the reasons for the leakage of the automatic exhaust valve are that the valve plate inside is not closed tightly. Here's how to fix it:

1. When the exhaust valve is discharged, the pressure inside is reduced, and the leakage is small, and the pressure inside is large when the water is not released, and it will leak badly.

2. The exhaust valve is copper, you can unscrew the base completely, and then twist it around two circles of waterproof tape or hemp rope to see, and it will generally not leak.

3. The exhaust valve is dismantled, and there are small parts connected together with springs, and the springs are ribbed and screwed. There are rubber pads the size of a grain of rice inside. Take it down, rub it, and then install it.

Pay attention to the direction of the white plastic block structure, pay attention when dismantling, and don't make a mistake when installing. If the water leakage is not serious, poke it a few more times, and the general situation can be solved.

Due to the process of water injection and pressure test, air will enter part of the pipeline, worried that this will affect the heating effect, and unscrew the exhaust valve to release the air, but because the internal connection of the exhaust valve is thin, it is easy to break if it is not operated properly, resulting in water leakage. Don't panic at this time, you can find a round chopstick, use the chopsticks as a wedge and nail it into the leak, and then ask a professional to repair it.

You can find the company you installed after-sales to see if it can be repaired The exhaust valve is a separate accessory, if it can't be repaired, just replace it.

We are Pengchengda water separator, and the exhaust valve leakage can only be replaced. But it's hard to change it yourself. It is recommended that you find a professional person to change. What does an exhaust valve look like? I can give you one if it's appropriate.

You can change an exhaust valve, the quality of the water separator you bought is not good, and it is good to change it to Gada or Weijia.

You can change a drain valve, generally the manufacturers who sell water separators have separate leak valves, Gada, Xinfan are good.

The exhaust valve is a small copper valve, generally one to two pieces of one, just buy one and replace it, and some special, depending on the type of radiator you have, if the general place is not sold, go to the place where you sell your radiator to buy and replace it, before changing, turn off the water valve, and use the basin to connect half a plate of water, just replace it.

Under normal circumstances, it will not leak.

In this case, it is first necessary to clarify the main situations of the leakage of the exhaust valve: the pipeline system is not flushed as necessary, or the flushing is not thorough, and the impurities and dirt in the pipeline enter the automatic exhaust valve and hinder the action of the floating device, so that the exhaust port cannot be closed; The automatic exhaust valve does not participate in the water pressure test, and after installation, the test is not carried out, resulting in the existing radiator exhaust valve can not bear the load of water; After installation, the installation adjustment was not carried out, and the exhaust valve was not screwed into the appropriate position, which hindered the operation of the floating device in the valve.

Hello answer, I have seen your question and am sorting out the answer, please wait a moment Hello, I have seen your question and am sorting out the answer, please wait a moment Ask?

But after exhausting, it is not leaky.

Question: When the water came out when it was deflated, the screws were loose, and the water kept coming out, is it normal to take a large basin of water.

Question: The screws are tightened without leakage.

Asked how much water to put in the right amount, I took a large basin.

It's that the float in the exhaust valve is not ticketed, and it should be hit a few times with a hammer, pay attention not too hard, so hahahaha.

It is better to buy an Italian or brand heating exhaust valve.

Is the gasket broken? It is best to find a professional to solve it.

If the return valve can drain water, it means that the pipe is unobstructed.

If the inlet valve does not drain, it should be that the valve is blocked.

Because of the water quality, the heating hot water contains a lot of magazines, so it is easy to cause blockage, and if the inlet valve is broken, you can only wait for the heating period to pass before replacing it.

When the air release valve is opened, the water is not out of the water, and the water is returned.

If the pipe is hot and the water cannot be discharged, it may be that the exhaust valve is blocked, so you close the main valves for both the inlet and return water, and remove the exhaust valve to see.

If you can't release water, it may be blocked by dirt, you open the sewage valve, find a steel wire and poke it in, and it may come out with water.

When ventilating the floor heating, we must first be clear about the heating method, which can generally be divided into two ways: central heating and self-heating

1. Central heating: for central heating, the pressure is relatively large, and it has no effect on whether the main valve of the return water is closed when deflated, and it can be deflated;

2. Self-heating: For self-heating, it is circulated by the circulating pump in the wall-hung furnace, so if we do not close the main return valve, it is easy to suck the air into the floor heating pipe, resulting in more air volume and air blockage; Therefore, it is necessary to close the main return valve before it can be deflated.

Looking for a property, draining the water yourself is to open the inlet valve, close the return valve, and then open the exhaust valve, but it will not appear in the situation you said.

If you don't understand it yourself, just look for a property. They have to take care of it, and they have to pay the property fee to solve the problem.
