To maintain a comfortable heat balance in the house at all times, an element such as a three-way valve on the heating system that distributes heat evenly to all rooms is included in the heating circuit. Despite the importance of this unit, it is no different in complex design. For the cong ty van cong nghiep this is a very important matter.
Three-way valve functions
The water that is supplied to the radiator has a certain temperature, which often cannot be influenced. The three-way valve regulates by not changing the temperature, but the amount of liquid. This makes it possible, without changing the area of the radiator, to supply the necessary amount of heat to the rooms, but only within the power limits of the system.
Separation and mixing equipment
Visually, the three-way valve looks like a T-piece but performs completely different functions. Such a unit, equipped with a thermostat, belongs to the valves and is one of its main elements. There are two types of equipment: separation and mixing.
The first is used when the coolant must be supplied simultaneously in different directions. The node is actually a mixer and forms a stable current with a set temperature. Mount it on the network that controls the heated air and water supply systems.
Products of the second type are used to combine the currents and their thermoregulation. Two openings are provided for inlet flows with different temperatures and one for their outlet. Apply them to the device of heat-insulated floors to prevent overheating of the surface.
Three-way valve and temperature controller are available separately on the market. For autonomous heating systems, the purchase of a thermostat design is considered a more rational and efficient solution.
The design of the three-way cranes
Due to construction design, the valves are divided into saddles and rotating. The operating principle of the former is based on the rhythmic movement of the rod vertically. The tuning saddle is the adjustment circuit. This type refers to mixing valves. The control is often carried out by an electromechanical drive.
A key element of the rotating structure is a rotating sector. During movement, the rod acts on the ball valve and the coolant is partially or completely cut off. This adjustment scheme is called a ball socket. These devices have high wear resistance. They are adapted to large temperature differences and are classified as valves. In private homes, where water is consumed in relatively small quantities, they can function as mixers.
A characteristic of the mixing valve is the presence of one outlet and two inputs. It is designed to control the temperature of the working fluid by combining high and low-temperature currents. With the right installation, the product can separate and separate the power. The three-way valve of the separating type is used when it is necessary to feed the hot coolant in different directions. All models of such cranes differ in some ways:
- Shutter mechanics – it can be exciting or filling up
- The shape of the stump – there are L, T, S-shaped
- Shutter type – found cylindrical, spherical, tapered
- Connection to the circuit – use of the coupling, flange, by welding, etc.
- Control method – automatic, semi-automatic, manual.
The mixing device is equipped with a rod placed in the middle. The ball valve in it is one. It blocks the shutter inlet at the right time.
