Abstract
The utility model relates to a fire protection facility, particularly a hydrant which is arranged on the ground. The utility model has the main technical proposal that the upper part of a valve body is connected with a protective connecting pipe, a bolt body is arranged on the protective connecting pipe, a valve clack is arranged in the valve body, a valve rod is connected to the valve clack, and a transition middle section is arranged between the valve body and the protective connecting pipe. The lower part of the valve clack is connected with a sealing plate, the inner wall of the valve body corresponding to the sealing plate is provided with an inward retractile step, and the sealing plate and the step are matched for sealing. The step point of the valve body is provided with a sealing ring, the sealing plate and the sealing ring are matched for sealing, and the lower part of the valve body is connected with a water inlet bent pipe. When the hydrant suffers accident collision, the hydrant can avoid the problem of the serious leakage of fire protection water.
Description
Technical field
The utility model relates to a kind of fire fighting device, refers in particular to a kind of hydrant that is arranged at ground.
Background technology
In the prior art, the hydrant housing that is installed on ground is formed by integrated poured usually, and when being wound when having an accident bump, water for fire can be gushed, and causes a large amount of wastes of tap water, and the flood tide ponding in the road, can cause the interruption of communication accident.
Summary of the invention
The purpose of this utility model is to design a kind of impairment type post fire hydrant, when colliding to avoid hydrant to have an accident, the serious problem of leaking of water for fire takes place.
Its main technical schemes is that the connection protection is taken on valve body, on protection is taken over the bolt body is set, and flap is arranged in valve body, connects valve rod on flap.
Joint between valve body and protection adapter, being provided with excessively; Connection driving fit plate below flap is provided with the step of inside contraction, driving fit plate and step fitted seal corresponding to the position of driving fit plate on the inwall of valve body; Step place at valve body is provided with the driving fit circle, driving fit plate and driving fit circle fitted seal; Connection water inlet bend pipe below valve body.
The utility model has the advantages that since between valve body and bolt body, increased the lower protection of strength ratio take over excessively in save two parts, when the bolt that has guaranteed to be exposed to ground on structure design is experienced bump, the plane of disruption necessarily appears at protection adapter place, make other position avoid damaging, protected the higher parts of cost such as valve body, water inlet bend pipe and flap to sustain damage, during maintenance, only needing to change the lower protection of cost takes over, when also having avoided bump simultaneously, the problem that water for fire is gushed takes place; Secondly; with the installation position of valve rod from original bolt body move to valve body and excessively save between; this improvement has guaranteed when fracture is taken in protection; the driving fit plate still is close on the driving fit circle; still has excellent sealing performance; guarantee that water for fire can seepage and go out, saved water for fire effectively, and avoided causing traffic accident.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in the figure: the connection protection takes over 2 on valve body 6, takes on 2 in protection bolt body 1 is set, and flap 5 is arranged in valve body 6, connects valve rod 4 on flap 5.The top of bolt body 1 connects stopper, when the needs rotation valve rod, special tool can be inserted in stopper, is enclosed within on the connecting rod that is connected in the valve rod upper end; Side at the bolt body can connect delivery port, on delivery port seal cover must be set, in order to avoid water leaks, when needing fire fighting, flexible pipe is connected on delivery port.Other position of the strength ratio hydrant that protection is taken over is little, so that when bump takes place, fracture is earlier taken in protection, guarantees that other position is injury-free.Valve rod is used to connect flap, and flap is used to install the driving fit plate, and the driving fit plate is used for and driving fit circle fitted seal, and to guarantee hydrant time spent not, water can seepage.
Joint 3 between valve body 6 and protection adapter 2, being provided with excessively.Save in the whole height of regulating hydrant excessively.
Connection driving fit plate 7 below flap 5 is provided with the step of inside contraction corresponding to the position of driving fit plate 7 on the inwall of valve body 6, driving fit plate 7 and step fitted seal.After step is set, can guarantee that soft driving fit plate can play good sealing function.
Step place at valve body 6 is provided with driving fit circle 8, driving fit plate 7 and driving fit circle 8 fitted seal.The purpose that increases the driving fit circle is further to improve its sealing property.Connection water inlet bend pipe 9 below valve body 6 can connect the water inlet pipe of tap water, for hydrant provides water for fire on the water inlet bend pipe.
Claims (5)
1, impairment type post fire hydrant is characterized in that (2) are taken in the connection protection on valve body (6), takes on (2) in protection bolt body (1) is set, and flap (5) is arranged in valve body (6), goes up at flap (5) to connect valve rod (4).
2, hydrant according to claim 1, joint (3) in it is characterized in that between valve body (6) and protection adapter (2), being provided with excessively.
