(Summary description)Shut-off valve: In terms of appearance, it can be divided into straight type shut-off valve and angle type shut-off valve; that is, the straight valve and angle valve installed in front of the radiator, which are mainly characterized by simple flow path, dead zone and vortex The area is small, with the help of the flushing effect of the inner wall of the valve, it can effectively prevent the medium from clogging, that is, it has better self-cleaning performance; and the flow resistance is small, and the flow coefficient is larger than that of a single-seat valve, which is equivalent to the flow coefficient of a double-seat valve. .

Information

Heating in winter is mainly based on water heating in most areas, whether it is independent heating or central heating; the pipe fittings that control the heating system are still valves, and there are many types of valves, and there are no less than ten of them used in heating systems. Kind of, these are a bit far from our lives, but the valves that are closely related to our lives are the valves of the domestic heating system. Generally speaking, they can be divided into three types, one is the globe valve and the ball valve; let’s understand the relevant knowledge together. :

1. Cut-off valve: From the appearance, it can be divided into straight cut-off valve and angle cut-off valve; that is, the straight valve and angle valve installed in front of the radiator, which are mainly characterized by simple flow path and dead zone. The vortex area is small, and the inner wall of the valve can effectively prevent the medium from clogging, that is, it has better self-cleaning performance; and the flow resistance is small, and the flow coefficient is larger than that of a single-seat valve, which is equivalent to that of a double-seat valve. Flow Coefficient;

2. Ball valve: the valve core is a sphere, and there is a straight passage in the middle of the sphere. When we rotate this passage to the same direction as the heating pipe, the water flow can pass; and when we rotate the direction of the sphere core pipe When it is perpendicular to the heating pipe, the closed state is handled. Its main feature is that the switch has a short diameter, and we only need to rotate it 90 degrees to solve it; it has the characteristics of wear resistance, pressure resistance, strong airtightness, and long service life;

The above two kinds of valves are commonly used valves in household heating systems. They are very common in the market. Sometimes they are called differently. In fact, the principles are the same. In addition, there is a vent valve on the plug in the upper right corner of the radiator, which is also A kind of shut-off valve, which adjusts the size of the valve opening by rotating a bolt; in short, as long as we have a comprehensive understanding of the valve we use, we can avoid damage to it during use, and it can also be timely when there is a problem with the valve Effectively repair or replace it.
