Problems solved by technology

In the prior art, the opening stroke of the spool is the maximum extension length of the valve stem, and there is no adjustment structure for the stroke of the spool. If the spool opening is too large, it will affect the flow balance in the pipeline, which can only be controlled manually. The opening degree of the spool is easy to cause misoperation
In addition, the dial on the handle in the prior art can only display the scale mark within one rotation, but for a balance valve with a large stroke, the scale mark of one circle obviously cannot completely record the rotation scale, which may easily lead to scale recording errors

Abstract

The invention provides a static balancing valve, which belongs to the technical field of valves and solves the problem that the conventional static balancing valves are easy to cause scale recording errors. The static balancing valve comprises a valve body, a valve rod, a valve core and a handle, wherein the valve core is positioned in the valve body; the valve rod is axially fixed in the valve body; the valve core is circumferentially fixed at a water-through cavity of the valve body and is in threaded connection with the inner end of the valve rod; the outer end of the valve rod is connected with the handle; and an adjustment mechanism capable of adjusting the travel of the valve core relative to the valve rod is arranged between the valve rod and the valve core.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a static balance valve. Background technique [0002] With the improvement of people's energy-saving awareness, the country vigorously promotes central heating. Many residential hot water supply pipe networks often supply heat to several buildings from a boiler room (or heat station), and the main pipe, several branch pipes, and each branch pipe are connected to the building. Composed of branch pipes connected to the inlet. Since each building is different from the heat source, if there is no effective equipment to eliminate the residual pressure in the near loop, the flow distribution will not meet the design requirements, resulting in overheating at the near end and overcooling at the far end, and the uniform distribution of heat sources cannot be guaranteed. [0003] The static balance valve is an adjustable valve with digital locking function. It adopts a direct-flow valve body ...
