Gas industry, chemical, enterprisesfor processing oil and oil products, gas pipelines and water pipes for domestic use are just some of the industries in which the ball coupler is most often used. This choice is not accidental, features of this particular type of crane allowed him to take a leading position in relation to other models.
Crane ball coupling - why exactly?
Such a tap is the best choice for thosePipeline systems that have a small diameter. The raw material, from which the brass ball brass clutch is made, is, as its name implies, brass. It is the most safe material used in pipeline systems. The nut, which is located under the handle, regulates the seal of the stuffing box. In the crane itself there are seals made of Teflon, which are movable elements with respect to the crane rod. If leakage occurs, simply tighten it (this will press the seal ring, and the normal operation of the crane will be restored). Due to the peculiarities of its design, the ball coupling valve easily withstands 2 tens of thousands of openings / closures. Another distinguishing feature of this model is its safety. This reputation was obtained due to the fact that the rod is in the body. Because of this, even if the nut is completely unscrewed or the working pressure is much higher than the standard, the rod can not fly out.
According to the shape of the shutter, the ball couplings are divided into the following types: a butterfly-handle and a long handle.
If the diameter of the crane is small, then it is usuallya butterfly gate is used. Opening the crane in this case does not require significant effort, and the design itself will look like a neat and compact. They are also good for those cranes that are close to each other.
A long handle is suitable for a crane of any diameter, however, with their close arrangement, such a handle can interfere.
Among the main advantages of a ball coupler:
If we consider its technical parameters,such a tap can be used in a pipeline supplying hot water, non-aggressive liquid, cold water, steam (provided that its temperature does not exceed 150 degrees Celsius). The valve stem and ball are made of brass, as is the case. The design works faultlessly at a pressure of 1.6 MPa.
The advantages of a ball valvemuff, are obvious. The simplicity of its design, ease of operation and safety of use explains the high popularity of this product (both in production and in residential buildings).
