Problems solved by technology

[0004] However, the commonly used spherical valves often only have the function of shutting off in the water supply and heating systems. The spool structure of the spherical valves currently on the market is a circular diameter structure, although it can also be controlled by changing the valve opening. The flow capacity of the pipeline (that is, to control the flow), but the flow linearity of the spherical valve core is very poor, which cannot meet the purpose of adjusting the flow in the actual production process

Embodiment Construction

[0020] In order to clearly illustrate the technical features of the solution of the present invention, the solution will be further elaborated below in conjunction with the accompanying drawings and through specific implementation methods.

[0021] Such as Figure 1 to Figure 5 As shown in , a new type of spherical valve core is provided, which includes a spherical valve core body 1 as a whole, and the valve core body 1 has a through flow channel 1.1 and a groove 1.2 for installing the valve stem. It has openings at both ends and respectively has a V-like opening structure and a circular opening structure with a semicircular arc-shaped head.

[0022] In this embodiment, the flow channel 1.1 is a spherical hollow structure inside the valve core body 1, the central axis where the valve stem is located perpendicularly intersects the central axis of the flow channel 1.1, and the groove 1.2 and the valve core The flow channel in the body 1 is directly in an impermeable structure, ...

Abstract

The invention relate to a novel spherical valve element. The valve element comprises a valve element body (1) which is integrally spherical, the valve element body (1) is provided with a through flow channel (1.1) and a groove (1.2) used for installing a valve rod, and the flow channel (1.1) is provided with a V-like opening structure and a round opening structure which are provided with semi-arc-shaped heads and are provided with openings in the two ends respectively. The valve element has the advantages of good flow linear proportion, high mechanical strength, corrosion resistance and long service life.

Description

technical field [0001] The invention relates to the field of pipeline flow control, in particular to a flow control valve, in particular to a novel spherical valve core. Background technique [0002] In the existing water supply and heating system, more and more attention is paid to the solution of the hydraulic balance problem. The current relatively advanced solution is to install flow regulating valves on each branch pipeline to precisely control the flow distribution of each branch. At the same time, the flow regulation performance of the flow regulating valve installed on each branch pipeline is getting higher and higher. Since the regulating valve is installed on each branch pipeline, the quantity required for installation is relatively large, so the economical requirements for the valve Also getting higher and higher. [0003] During the installation process of the above-mentioned control valves, since most of them belong to technical transformation projects, the in...
