Abstract

The invention discloses a straight-flow regulating valve which belongs to the technical field of valve manufacturing, aiming at solving problems that the passage of valve body of the existing regulating valve is winding, the resistance is great when liquid passes through, etc. The straight-flow regulating valve comprises a valve body, wherein a hollow cavity is formed in the valve body; a water inlet and a water outlet are respectively arranged at the left side and the right side of the valve body; a valve core is arranged in the valve body; the inner end of a valve rod is connected with the valve core, and an outer end stretches out of the valve body and is connected with a hand wheel; a connecting rod which is in threaded connection with the valve body is arranged on the valve core and is arranged along a connecting line between the water inlet and the water outlet of the valve body; the valve rod is vertical to the connecting rod, and a worm rod is arranged on the valve rod; a turbine which is meshed with the worm rod is fixedly connected in the valve body along an axial direction; and the turbine is fixedly connected with the connecting rod along a peripheral direction. The straight-flow regulating valve has the characteristics of low resistance and strong flowing ability when the fluid passes through the valve body.

Description

technical field

[0001] The invention belongs to the technical field of valve manufacturing, and relates to a regulating valve, in particular to a direct-flow regulating valve. Background technique

[0002] In the automatic control of modern factories, the regulating valve plays a very important role. By receiving the control signal output by the regulating control unit, the process parameters such as medium flow, pressure, temperature and liquid level are changed by means of power operation to achieve the correctness of the medium. distribution and control.

[0003] A regulating valve generally includes a valve body with a cavity inside, a valve core, a valve stem and a handwheel. , one side of the valve body is the water inlet, and the other side is the water outlet. The shape of the existing valve body is generally T-shaped or inclined. The fluid enters from the water inlet at the lower part of the valve body and flows through the valve core and valve core seat Then go o...
