Among the existing fire hydrants (such as: a kind of outdoor fire hydrant that automatically gets rid of residual water, public (announcement) number CN203303548U; a kind of novel ground fire hydrant, public (announcement) number CN204662558U; a kind of fire hydrant that can automatically decompress and stabilize the pressure, Publication (announcement) No. CN207633431U;) all adopt valve body or valve stem all are one-piece molding structure, can't fit and install and be applied to the fire hydrant outer cylinder body of different types, different size models, promptly a kind of valve body or valve stem can only Corresponding to one type of fire hydrant outer cylinder, it is obvious that the current integrated packaging structure of fire hydrants damages the valve body or valve stem. If other valve bodies or valve stems of different sizes are replaced, the corresponding model size needs to be replaced. The outer cylinder of the fire hydrant not only leads to unnecessary waste of fire hydrant equipment, but also inconvenient assembly and disassembly. Moreover, with the development of the Internet of Things technology becoming more and more popular, it is necessary to carry out intelligent transformation of the existing fire hydrants to realize the intelligent control of the network of fire hydrants.

The pressure measuring device is installed at the bottom of the valve stem;

or the pressure measuring device is mounted on the valve disc at the bottom end of the valve stem;

Alternatively the pressure measuring device is mounted on the valve seat located at the bottom end of the hydrant.

As a preference: the valve stem is provided with a height adjustment mechanism for adjusting the vertical height of the valve stem according to the outer cylinders of fire hydrants of different sizes. Among them, the upper and lower heights of the valve stem refer to: the effective height between the bottom end of the valve stem and its top end, or the effective height between the bottom end of the valve stem and the upper flange installed on the top of the outer cylinder of the fire hydrant.

As a preference: the intelligent integrated rod of a fire hydrant in the present invention also includes a lifting and pulling mechanism for pulling the valve rod to move up and down.

As a preference: the intelligent integrated rod of the fire hydrant in the present invention also includes a limiting mechanism for limiting the rotation of the valve rod. Wherein, "limit" refers to the limited movement of the valve stem or the adapter rod in the direction of circumferential rotation, excluding the limited movement of the up and down movement direction. Moreover, the position-limiting mechanism is independent of the outer cylinder of the fire hydrant, eliminating the need for snap-fit connections between the transfer rod and the guide groove on the inner wall of the outer cylinder of the fire hydrant in existing products.

The limit mechanism is used to limit the rotation of the transfer rod or the valve rod in the direction of its circumferential rotation, so that the transfer rod and the valve rod are always maintained during the movement of the transfer rod and the valve rod by the lifting traction mechanism. Move up or down without deflecting the adapter rod and valve stem.

As a preference: the intelligent integrated rod of a fire hydrant in the present invention also includes an upper flange, which is used to erect the valve stem in the outer cylinder of the fire hydrant; The installation hole of the outer cylinder; the smart cap is installed on the outer cylinder of the fire hydrant, and the smart cap is located above the upper flange.

At the same time, after the screw rod is effectively lengthened, it can also serve as a height adjustment function for the up and down height of the valve stem. By rotating the screw rod with a wrench to pull the valve stem up and down, the adjustment control of the up and down height of the valve stem is more fine and precise.

In this way, when the height adjustment mechanism is not accurate enough to regulate the height of the valve stem up and down, you can use an external force (such as a wrench) to turn the screw to pull the valve stem up and down to move up and down to realize the fine adjustment of the valve stem's up and down height, so as to realize the product of the present invention.
