Do you know what a Schroeder valve is?

The Schroeder valve is a device whose main function is to connect the parts of the refrigeration mechanism to the pipeline. Most often it is a filling hose or a manometric collector.

What is a Schroeder valve? Appointment

This mechanism serves mainly forevacuation of refrigerating circuits. This is necessary to remove old refrigerant particles, so that the filling proportion is observed and excess moisture is removed from the system. By the way, even the smallest moisture content can provoke a small freezing of the cavity of the refrigeration equipment parts or create a partial clogging. All this leads either to changes in the cycle of work, or to a complete breakdown and functionality of the refrigeration unit. Also, Schroeder's valve is very popular among repairmen of refrigerators.

Thanks to this element can be very fast andit is inexpensive to connect a manometric collector to the compressor. Most often after filling, the valve remains in place - this is necessary in order to subsequently monitor the slightest changes in the system. Of course, it is not left open on the spot, it is additionally put on a special protective cap.

Device

The Schroeder valve consists of several structural elements.

1. Housing. Most often this element is a brass part of a cylindrical shape. On the body there are two threads - internal and external. The first is assigned to fix the nipple device, and the second is used to connect the brass part of the valve to the manifold.
2. Cap. This element has in its design a small rubber sealant, which is able to maximally protect the circuit from a sudden "sucking", which is not uncommon for modern refrigerators. This phenomenon often occurs due to leakage of the air valve.
3. Valve. This is the main mechanism, which provides a one-way supply of refrigerant in only one direction.
4. Retraction. Most often, the bends are made of copper pipe. Its diameter is about a quarter of an inch. The length of the tap is 50 to 90 millimeters. The copper tube is used for flaring.

Manufacture of a valve and its sale in the Russian market

Most modern valve models,presented in the modern Russian market, are a product of Chinese manufacture. Such devices are characterized by a lower price, but as practice shows, their manufacturing quality is far inferior to our counterparts.

Naturally, there is a need for solderingconnections of the discharge pipe to the valve body. In this regard, many prefer the valves of domestic production. They are practically not inferior to the Chinese for the price, but they are more reliable and qualitative in use. Find them is not difficult - they are sold in any specialized store in the city.

So, we found out what the Schroeder valve is, what structural elements it consists of and what it is used for.
