Technical Field

The utility model relates to a fire hydrant technical field, concretely relates to slot connection formula underground fire hydrant.

Background

The outdoor fire hydrant is a water supply facility arranged on a fire-fighting water supply pipe network outside a building, is mainly used for a fire truck to take water from the municipal water supply pipe network or the outdoor fire-fighting water supply pipe network to put out a fire, can also be directly connected with a water hose and a water gun to discharge water to put out a fire, and is one of important fire-fighting facilities for putting out a fire; general structure says, and it rotates the valve rod through the hand wheel, makes case, valve clack relative movement to open the passageway, at the water inlet kneck installation water inlet elbow of valve body, at water outlet department installation fire control interface, nevertheless there are multiple connected modes in water inlet elbow mouth of a river department, like ring flange butt joint, ditch slot type connection, easily at the during operation, there is unmatched phenomenon with fire fighter's fire hose nipple, needs to improve.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical defect, the utility model provides a following technical scheme:

slot connection formula underground fire hydrant, including the fire hydrant body, the below of body is provided with into water interface, and the top of body is provided with the delivery port, and the outer end of delivery port is provided with the fire control interface that is used for connecting the fire hose, and it is provided with into water elbow to intake interface outer end, and the position of adjacent end portion sets up the ring flange on the return bend of intaking to open annular groove at the tip of the return bend of intaking, and set up the clamp on the return bend of intaking at the ring flange back.

The fire hydrant integrates flange connection and groove connection, and is more convenient to use.

Furthermore, an annular fixing band is arranged on the water inlet bent pipe on the back of the flange plate, one side of the fixing band is provided with a groove, and a clamp is placed in the groove.

Because of this fire hydrant is placed outdoors, and the groove connection needs the clamp cooperation, and the clamp generally is by bolt fastening, wets for a long time, like under the condition such as drenching, and the bolt easily rusts, consequently holds the bolt with the fixed band fluting to facilitate the use.

Furthermore, the device also comprises an end cover, wherein the outer wall of the end cover is provided with a threaded section, and the inner wall of the corresponding fixed belt groove is provided with a threaded section.

For the leakproofness of further improvement clamp, add the end cover to the end cover cooperation fixed band forms the sealed chamber that holds the clamp, avoids it to expose under sunshine or rainwater for a long time.

Furthermore, the end cover is provided with a convex column.

The force is applied conveniently, and the end cover is convenient to unscrew.

Further, the clamp comprises an upper portion and a lower portion, the end portions of the upper portion and the lower portion are fixed through bolts, and the clamp is practical in structure and convenient to use.

Furthermore, the water inlet elbow is connected with the water inlet interface by a groove.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the fire hydrant integrates the flange and the groove into a whole, is convenient to butt and is convenient to use.

Drawings
