What is the axle box for, what are its types, how is the

We are so accustomed to good things that we don’t even remember when the last time we saw an ordinary faucet in the kitchen or in the bathroom, but not a faucet. The device allows you to create the necessary power of water flow and temperature, increasing the comfort and convenience when using water supply. The main element of the mixer is the crane-box, the quality of which determines the period of use of the product without carrying out repairs.

Install it inside the structure and is used to open or block the water flow. Below we will talk about the crane-box in more detail, in particular, its types, selection, replacement and repair.

Kinds

In the plumbing market today, you can find two main types of such devices. Now let's see what the technical characteristics of the crankshaft are in each of them.

Ceramic

Below is a description of the crane axle box:

1. The product has a simple design.
2. It is made of two materials - ceramics and brass.
3. The mixer has 2 ceramic inserts with holes of the same shape:

• the first is mounted on the rod;
• the second is motionless.

1. To open the tap, turn the handwheel half a turn.

Tip: be sure to install a high-quality water filter in front of the ceramic faucet, as the product is very sensitive to water.

1. Even with long-term use, the device is not erased.

Specifications:

Worm

The rubber cock has a stem that retracts during a worm gear. Due to this, the valve seat is covered with a rubber gasket.

When the latter becomes unusable, the valve begins to resonate and create an unpleasant hum in the pipes. Make a gasket of various types of rubber, depends on its shelf life, if necessary, it can be easily replaced with your own hands.

Select the advantages of the inner core with a rubber cuff:

• low cost of the product;
• repair and replacement do not cause difficulties even for inexperienced craftsmen;
• This type of crane is a common component, so it will not be difficult to acquire it.

Tip: you can independently cut a rubber gasket to replace worn one.

The disadvantages of the worm type:

• short service life;
• when opening and closing, turn the handwheel 3-4 times. In the end, due to frequent friction, wear occurs, which causes the valve to be tightened every time.

Choosing a crane-axle box

1. When selecting a new part, it is necessary to take into account its dimensions, which may be 1/2 and 3/8.
2. Pay attention also to the manufacturer of the device, if the ceramic or rubber crane box:

• "Under the square" - the domestic industry;
• "Under the slot" - on top of the rod 20 or 24 slot - imported.

1. Valves are produced, respectively, "under the slot" and "under the square". They are made of metal or plastic.
2. Before you make a choice, we recommend measuring the length of the rod and the crane.

Tip: Take your old crane bush and valve with you to the store or to the market to make it easier to pick.

1. Since the valve and valve are of a different standard, we recommend trying on the flywheel right before purchasing the product in the store.. Just keep in mind that the retaining flywheel bolt may be with a different thread.
2. Independently make sure which crane is installed in the mixer.

To do this, scroll through its valve:

• half a turn - ceramic;
• 3-4 - rubber.

On average, the cost of ceramic parts will be almost 2 times higher than rubber. We recommend to pay attention to the last option, if you do not have a water purification filter installed, otherwise ceramics will quickly fail.

How to independently replace or repair

Prepare the necessary tools in advance, then during work you will not have to be distracted due to unrecorded trifles.

You'll need:

• figured and flat screwdrivers;

• wrenches of the appropriate size, as well as pipe wrench;
• electric drill with slotted nozzle;
• pliers;
• a new crane-box or part to replace an item that has become unusable.

The following is an instruction for the replacement or repair process:

1. Unplug the faucet from the water system before changing the faucet. To do this, close the valves under the sink, and, if not, at the entrance to the housing. You should not begin repair, without performance of this item.
2. Determine which part you need to dismantle.
3. Remove the flywheel by unscrewing the plastic cap with a screwdriver and unscrew the locking screw.. So you will open access to the stock and crane box.
4. Take the key 17 and remove the crane. Sometimes there are lock nuts in ceramic taps, they must first be released with a wrench.
5. Unscrew the anti-square crankshaft with a 7-wrench anti-clockwise wrench.

Tip: if the screw on the handle of the crane rusted with time and it is impossible to unscrew it, drill out its cap with a drill, and then unscrew it. When this does not help, lubricate the thread with a rust solvent, wait as indicated in the instructions, and remove the part.

1. Clean the threads and the flywheel after removing the crane from the corrosion of the brush on the metal, then it will fit snugly to it.
2. When tightening a new part, try not to overtighten it, at the same time it will also not be enough to endure. It will get out with the flywheel.
3. Turn on the water and check the connections for leakage.

Although the repair of this sanitary part is simple, its frequent production will be unpleasant for the owner of the mixer. Therefore, when buying the latter, we recommend that you carefully consider the process in order to purchase only a high-quality device. Do not act on the principle - "the miser pays twice."

Properly selected mixer for many years will save you from repairs and accidents. Do not forget to check the device operation before purchasing (so that the valve is not jammed). We hope you have already decided which faucet of the axlebox is best for your plumbing system.

Conclusion

We use the faucet in the bathroom and in the kitchen several times a day, so when choosing a device, take care of the process. The main element in it is a crankcase, which can be worm or ceramic. In the latter case, you must ensure the protection of the plumbing with a quality filter.

Otherwise, ceramics will quickly fail. Installing an element in the mixer is not difficult, and you can do it yourself in a short time.
