Problems solved by technology

The problem is that the valve stem is integral. Once the fire hydrant is hit, the valve stem will bend and deform, which will lead to the phenomenon that the valve plate is not tightly sealed, and the self-closing anti-collision fire hydrant does not solve the problem of quick opening. The problem

Embodiment Construction

[0019] Describe in detail below in conjunction with accompanying drawing, as figure 1 , figure 2 , image 3 shown.

[0020] A quick-opening fire hydrant has an overall structure including a body 1 , a base 2 , a valve body 3 and a base 4 . The body 1 and the base body 2 are connected by connecting bolts 25 , and a sealing ring or gasket is provided between the body 1 and the base body 2 . The base body 2 and the valve body 3, and the valve body 3 and the base 4 are connected by connecting screws 30, and sealing rings or gaskets are also provided at the joints. In order to combine tightly and reliably, the joint surfaces between the body 1 and the base body 2 and between the base body 2 and the valve body 3 adopt non-uniform tongue-and-groove structures.

[0021] The valve body 3 is provided with a valve plate sealingly matched with the end surface of the medium flow port, and the axially movable valve stem connected with the valve plate protrudes from the body and is conn...

Abstract

The invention belongs to fire-fighting equipment, and relates to a quick opening hydrant which mainly achieves quick opening. The quick opening hydrant comprises a body, a valve body and a base, a valve plate in seal fit with a medium circulation port end face is arranged in the valve body, and a valve stem connected with the valve plate and capable of moving axially extends out of the body and is connected with a rotating structure arranged on the body. The quick opening hydrant is characterized in that a base body is connected between the body and the valve body through fasteners, the rotating structure comprises a ball which is arranged in a groove at the top end of the valve stem and partially protrudes over the groove, a cam is arranged in a cam chamber arranged at the upper end of the body and tightly pressed by a cover plate, a cam end shaft extends from a through hole in the cover plate, and a working surface of the cam keeps in contact with the ball constantly. The hydrant is capable of achieving quick opening and has functions of pressure regulating and pressure stabilizing, antifreezing and self closing after breakage.

Description

technical field [0001] The invention relates to fire fighting equipment, in particular to a quick opening fire hydrant. Background technique [0002] The traditional above-ground fire hydrant is an outdoor above-ground fire water supply facility. It is used to supply water to fire trucks or directly connect with hoses and water guns for fire extinguishing. It is a special facility for outdoor necessary fire water supply. The upper part of the utility model is exposed to the ground, the mark is obvious, and the utility model is convenient to use. The ground fire hydrant is a necessary fire-fighting equipment in the city, and it is widely installed in densely populated areas such as factories, mines, warehouses, docks, freight yards, high-rise buildings, and public places. The traditional fire hydrant structure is composed of parts such as valve body, valve stem, self-draining valve and interface base. The opening of the fire hydrant is by rotating the spiral valve stem to ...
