Description

Balancing valve

Technical Field

The utility model relates to the technical field of balance valves, in particular to a balance valve.

Background

The balance valve is a valve with special functions, has no special character, is suitable for large pressure difference or flow difference in each part of the pipeline or the container, and is arranged between the corresponding pipelines or the containers for reducing or balancing the difference, so as to adjust the relative balance of the pressure at two sides or achieve the balance of the flow by a flow dividing method. At present, the balance valve on the market can't carry out corresponding regulation according to the pressure of pipeline inside fluid in the use, and when the impact force of balance valve inside was insufficient, the valve body inner chamber would produce pressure differential for inside fluid will receive the influence, and fluidic mobility is just also followed to diminish, thereby leads to unable demand that satisfies the use.

The self-operated balance valve comprises a valve body, wherein a T-shaped cavity formed by combining a longitudinal cavity and a transverse cavity is arranged in the valve body, the lower end of the longitudinal cavity forms a water inlet, the right end of the transverse cavity forms a water outlet, a valve core capable of sliding in the longitudinal cavity is arranged at the junction of the transverse cavity and the longitudinal cavity, the upper end of the valve core is connected with a driving rod axially arranged along the longitudinal cavity, the driving rod penetrates through a through hole formed at the upper end of the valve body to be connected with an elastic component, and the elastic component is arranged at the upper end of the valve body. According to the novel self-operated balance valve, the elastic component is arranged outside the valve body, so that unstable water flow caused by direct contact of water flow can be avoided, the elastic component is not in direct contact with water, and parts with relatively low cost such as iron materials can be used; the cavity is arranged in a T shape, so that a water inlet and a water outlet can be conveniently formed respectively, and the driving valve rod can be conveniently installed. However, when the T-shaped cavity is subjected to overlarge or undersize fluid in the pipeline, the internal impact force is changed along with the change, so that the balance of the fluid in the cavity cannot be maintained, the fluidity of the fluid in the cavity is affected, and the smooth state of the fluid cannot be met.
