Abstract
The utility model discloses an anti-collision outdoor above-ground hydrant which is mainly composed of a body, a valve seat and a safety bolt. The utility model is characterized in that the strength of the safety bolt by which the body and the underground part of valve seat are tightly fixed is lower than the strength of the body and the valve seat. The utility model has the advantage of convenient maintenance. By experiment, when the utility model is impacted, the safety bolt is broken and the body and the valve seat are not damaged. Thus, only the safety bolt is replaced, and then the utility model can be reused, so the utility model saves time and labor.
Description
Technical field:
The utility model relates to a kind of fire-fighting equipment, relates in particular to the outdoor post fire hydrant of a kind of crash-proof.
Background technology:
Post fire hydrant is damaged after being knocked down by vehicle, and maintenance needs to change body, valve seat, even is embedded in the bend pipe of deep under ground, and the maintenance cost height is wasted time and energy.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, adopts the outdoor post fire hydrant of a kind of crash-proof.
To achieve these goals, it is the outdoor post fire hydrant of a kind of crash-proof that the utility model solves the technical scheme that its technical problem adopts, and mainly is made up of body, valve seat, breaker bolt, is characterized in; Body and the fastening breaker bolt of underground part valve body, intensity is lower than body and valve seat.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect.This practicality is easy to maintenance, is skillfully constructed.Through evidence, when bolt was subjected to colliding, the weakest local stress was the most concentrated, breaker bolt fracture, and body, valve seat all can't harm.Apart from screw thread partly about 8mm, the 8mm section is polygonal or flat pattern through the most weak fracture section of design safety bolt strength, can easily residual bolt in the screw be unloaded after making fracture, and breaker bolt also can just not design polygonal or the flat pattern section to twisting.Can reuse as long as change breaker bolt, time saving and energy saving, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is another kind of structural representations of the present utility model;
Accompanying drawing 3 is the part drawing of breaker bolt in the accompanying drawing 1;
Accompanying drawing 4 is the part drawing of breaker bolt in the accompanying drawing 2.
The specific embodiment
Valve body 3 referring to Fig. 1, Fig. 2, body 1 and under ground portion is fastening by breaker bolt 2.Referring to Fig. 3, breaker bolt 2 is in the polygonal or flat pattern section 4 at distance threaded portion 8 millimeter places, and design has fracture section 5.Referring to Fig. 4, to the breaker bolt of twisting then equally design fracture section 5 is arranged.Through evidence, when bolt was subjected to colliding, the weakest local stress was the most concentrated, the breaker bolt fracture, and body and valve body all can't harm.And after the breaker bolt fracture, can easily residual bolt in the screw be unloaded, after the breaker bolt fracture of twisting form, only need to change to get final product.
Claims (2)
1. the outdoor post fire hydrant of crash-proof mainly is made up of body, valve seat, breaker bolt, it is characterized in that: fastening body of breaker bolt and valve seat.
2. according to the outdoor post fire hydrant of the described a kind of crash-proof of claim 1, it is characterized in that: breaker bolt has the fracture section therebetween.
