Description

Spherical valve port pad

Technical Field

The utility model relates to the technical field of gas pressure regulators, in particular to a spherical valve port pad.

Background

The gas pressure regulating valve is a straight rod type and lever type pressure difference feedback control pressure regulating device. In the development process of a gas pressure regulator, the closing pressure of the pressure regulator is an important index for checking the performance of the pressure regulator.

At present, due to the limitation of processing precision, the parallelism between the valve port pad and the valve port cannot achieve an ideal effect, and therefore the closing pressure of the pressure regulator is too high.

Disclosure of utility model

The utility model provides a spherical valve port pad, which aims to: the parallelism of the valve port pad can be adjusted, and the pressure regulator closes the pressure.

The embodiment of the utility model is realized by the following technical scheme:

The utility model provides a spherical valve port pad, includes valve port and valve rod, the valve rod passes the valve port is connected with spherical valve port pad and valve port pad base, the valve port is located spherical valve port pad top, be provided with spherical concave surface on the spherical valve port pad one side, be provided with spherical convex surface on the valve port pad base, convex surface sliding connection is inside the convex surface.

Further, an annular groove is formed in the valve port pad base, and a sealing ring is installed in the annular groove.

Further, a pressing block is arranged on the valve rod and is abutted against one side, far away from the valve port pad base, of the valve port pad.

Further, the shape of the pressing block is cone-shaped.

Further, the end part of the valve rod penetrates through the spherical valve port pad to be connected with the spherical valve port pad in a sliding mode, and the end part of the valve rod is fixedly arranged in the valve port pad base.

The technical scheme of the embodiment of the utility model has at least the following advantages and beneficial effects:

The spherical concave surface is arranged on the spherical valve port pad, the spherical convex surface is arranged on the valve port pad base, and the convex surface is slidably connected inside the convex surface, so that the spherical valve port pad can rotate on the valve port pad to finely adjust the parallelism of the valve port pad and the valve port, and the condition of overhigh pressure of the pressure regulator is avoided.
