Embodiment Construction

[0018] The micro-flow regulating valve of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0019] like figure 1 Shown is a tiny flow regulating valve, including the valve part and the actuator. The valve part is composed of a valve body 1 with an inlet and outlet and a flow channel, a valve seat 3, a valve core 27, a valve stem 28 and a valve cover 6 and the like.

[0020] to combine figure 1 and figure 2 As shown, the valve seat 3 is an independent component, embedded in the valve seat hole on the valve body 1, and the annular gap between the valve seat 3 and the valve body 1 is equipped with a flexible graphite composite gasket 2 for the valve seat as a sealing element. . The outer wall of the valve seat 3 is provided with an annular flange-shaped flange embedded in the stepped hole of the valve body 1, and the flange-shaped flang...

Abstract

The invention discloses a small flow regulating valve, which includes a valve body, a valve seat, a valve core, and an actuator, and is characterized in that: the valve seat is an independent component embedded in a valve seat hole on the valve body , The sealing element is installed in the annular gap between the valve seat and the valve body, and the flow channel and sealing surface are set on the valve seat. The regulating valve is easy to replace and maintain quickly, and has good sealing effect.

Description

technical field [0001] The invention relates to a regulating valve, in particular to a small flow regulating valve. Background technique [0002] The regulating valve is composed of the actuator and the valve part. The valve part is composed of the valve body, the valve seat and the valve core in the valve body, the valve cover, the valve stem and other components. The main part of the actuator is a cylinder. The piston rod of the cylinder and the valve The valve stems are connected by connecting parts. Use the air source to control the action of the cylinder piston to push the valve core to open and close to adjust the flow. [0003] At present, the small flow control valves used to control the small flow of extremely toxic, flammable, explosive, volatile, and corrosive media generally have problems such as large volume, high cost, inconvenient maintenance, large leakage, and poor sealing performance. defect. The specific performance is: [0004] (1) The valve seat is f...
