Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

referring to fig. 1, a high-pressure duplex integrated instrument valve includes a valve body, and at least one control assembly is disposed on the valve body; the control assembly comprises a valve core, a valve rod, a packing box and a handle, one end of the valve rod is connected with the valve core, the other end of the valve rod penetrates through the packing box to be connected with the handle, the valve core is connected with the valve body in a matched mode, packing is arranged inside the packing box, and the packing and the valve rod are attached.

In this embodiment, be connected with valve-stem nut on the valve rod, valve-stem nut with the stuffing box cooperation is connected. The valve rod can be well rotated up and down through the valve rod nut, so that the valve rod can better drive the valve core to move up and down.

In this embodiment, the top end of the stuffing box is provided with a lock nut, and the lock nut is designed to well block the opening at the top end of the stuffing box.

In this embodiment, the top end of the valve rod nut is provided with a dust cover. The design of shield can block external dust well, can protect valve rod nut inside well.

In this embodiment, the handle is removably connected to the valve stem by a socket head cap screw. The disassembly and the assembly are convenient.

In this embodiment, the control assembly is provided with two, and respectively mutually symmetrical is connected with the valve body. The two pipelines are arranged, so that the control of the pipelines under various conditions can be well realized, and even if one of the pipelines is damaged, the other pipeline can be continuously used.
