Description
Technical Field
The utility model relates to a balance valve core assembly, and belongs to the technical field of balance valves.
Background
The balance valve is a valve with special functions, and the valve is not special in itself, but only in the difference between the use function and the place. In some industries, because of the large pressure or flow difference of the medium (various flowable substances) in each part of the pipeline or the container, in order to reduce or balance the difference, a valve is arranged between the corresponding pipelines or the containers to adjust the relative balance of the pressures at two sides or achieve the balance of the flow by a flow dividing method, and the valve is called a balance valve.
The patent application number cn201811403228.X discloses a balancing valve comprising: the valve comprises a valve body, a valve seat, a plug, a stop valve core, a steel ball, a first spring, a first check ring, a reversing valve core, a second spring, a spring seat, a control valve core, a second check ring, a third spring and a proportional electromagnet. According to the balance valve provided by the embodiment of the utility model, energy is saved, and a pilot handle and a hydraulic control proportional multi-way valve are not needed. However, in the action process, the balance valve core is easy to shake due to uneven stress, and the action stability is affected.
Therefore, a balanced valve element assembly is needed to improve the motion stability.
Disclosure of Invention
The utility model aims to solve the technical problems that: in order to overcome the defects in the prior art, the balance valve core assembly for improving the action stability is provided.
The utility model solves the problems by adopting the following technical scheme: a balance valve core assembly comprises two valve rods which are fixedly connected, wherein the two valve rods are coaxially and symmetrically arranged;

Preferably, the oil passage is provided coaxially with the valve stem.
Preferably, the number of the oil inlet holes and the oil outlet holes on the same valve rod is four.
Preferably, the four oil inlet holes and the four oil outlet holes are uniformly distributed circumferentially with the axis of the valve rod as the center.
Preferably, the two valve stems are of an integrally formed structure.
Preferably, the aperture of the oil inlet hole is 8mm.
