Abstract

The utility model relates to a fire hydrant, in particular to an anti-collision fire hydrant, which comprises a hydrant body and a hydrant housing. The hydrant body and the hydrant housing are in flanged connection with each other; the outer surface of the hydrant body is coated with a layer of fluorescent paint; a flange of the hydrant body and a flange of the hydrant housing are fixed with each other through a special element; and the strength of the special element is smaller than the strength of the flange of the hydrant body and the flange of the hydrant housing. Compared with the prior art, the anti-collision fire hydrant of the utility model prompts drivers to know the existence of the fire hydrant through coating the outer surface of the hydrant body with a layer of fluorescent paint, thereby avoiding vehicles from hitting the fire hydrant, and greatly reducing the hit probability of the fire hydrant; even if the fire hydrant is hit, a special bolt is just crashed, and the hydrant body, the hydrant housing and a valve body are in perfect condition, so that the fire hydrant is repaired conveniently and can restored only by replacing the special bolt; and meanwhile, the fire hydrant ensures that the great loss of a water source of a water system can not be caused because the special bolt is crashed.

Description

A kind of crashproof hydrant

Technical field

The utility model relates to a kind of hydrant, is meant a kind of crashproof hydrant especially.

Background technology

Hydrant stands on road both sides or some other public arena usually, because its volume is less, be difficult for coming into the picture, often by Vehicular impact, not only hydrant itself is damaged, the hydrant that need more renew, and High-Pressure Water is also gushed, not only waste precious water resource, may make that also the masses' property around the hydrant suffers heavy losses.

In order to address this problem, people have proposed various solutions, propose a kind of " crash-proof post fire hydrant " as Chinese patent CN2752334, above its key and the blue junction of bolt bodily movement of practising Wushu, be equipped with to hit and split plate, hit and split plate intensity and be lower than key flange and bolt bodily movement of practising Wushu orchid.When hydrant is subjected to clashing into, hit and split plate and at first rupture, effectively protect other parts of hydrant.And for example Chinese patent CN2900634 has proposed " a kind of crashproof hydrant ", mainly is made up of body, valve body, valve rod.Below easy to break section the piece gusset plate is arranged on valve body top, with the opposing external force collision.There is easy to break section in the body bottom, form plane of weakness.During external force collision, gusset plate and easy to break section relativity can guarantee crashproof hydrant in case rupture, and breakaway poing must occur in valve body with the upper part.And valve body adopts double-current journey self-closing valve, has to open light characteristics, is in self-enclosed state during normality, in case when hydrant was ruptured by external force collision, valve body was sealed High-Pressure Water, though hydrant is disconnected, can not there are flowing out.Chinese patent CN200952150 has proposed a kind of " crash-proof overground fire hydrant " for another example, mainly form by key, valve body and guide rod, it is characterized in that: key is connected by breaker bolt with valve body, guide rod in the key is divided into two sections, and by the connection of zigzag clutch, be with spring on the guide rod, the bottom of guide rod is provided with valve plug.The utility model is after being collided, and breaker bolt ruptures, and key separates with valve body, and guide rod separates with valve body with key and also separates and harmless, and key loses pressure after separating, and it is stable that valve encloses tray, and valve plug is still closed under spring action from bottom to top automatically.

Above-mentioned solution all is based on hydrant and how is farthest reduced the damage of hydrant after clashing into and avoid a kind of like this thinking of water resource loss to go to consider, it is by being provided with the damage that easy fracture portion avoids hydrant itself on hydrant, utilize the automatic water stopping function of main valve to avoid the loss of water resource simultaneously, make minimization of loss.And in fact, hydrant by Vehicular impact mostly because the driver does not notice that hydrant causes, and if hydrant itself has eye-catching sign to remind the driver, will significantly reduce the possibility that hydrant is clashed into.

The utility model content

Main purpose of the present utility model is to overcome the shortcoming that hydrant is easily clashed in the prior art, provides a kind of hydrant that significantly reduces by the crashproof hydrant of crashproof possibility.

The utility model adopts following technical scheme: a kind of crashproof hydrant, comprise a bolt body and a key, and flange connects between bolt body and the key, is coated with one deck fluorescent paint at the external surface of bolt body.

According to a better embodiment of the present utility model, to fix with a special element between the flange of described bolt body and key, the intensity of this special element is less than the intensity of bolt bodily movement of practising Wushu orchid and key flange.

Further, described special element is a special bolt, is fixed with nut on this special bolt.

Further, be provided with a planar seal ring between the flange of described bolt body and key.

Further, the flange of described key is provided with crashproof flange spoke.

According to a better embodiment of the present utility model, the external surface of described key is coated with one deck fluorescent paint.

By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of crashproof hydrant of the present utility model reminds the driver to note the existence of hydrant by the external surface coating one deck fluorescent paint at the bolt body, thereby avoid vehicle to knock hydrant, greatly reduce the probability that hydrant is clashed into.Moreover, the utility model also is provided with the special bolt of an intensity less than bolt bodily movement of practising Wushu orchid and key strength of flange between the flange of bolt body and key, even if hydrant is bumped against also and just special bolt is smashed, bolt body, key and valve body are excellent, it is convenient to repair, change special bolt and can reply former state, guarantee that simultaneously the water source of water system can not run off in a large number because of special bolt is broken the system water source of causing.

Fig. 2 is an A place enlarged drawing among Fig. 1;

Fig. 3 is a B place enlarged drawing among Fig. 1;

Fig. 4 is the perspective view of the utility model specific embodiment.

The specific embodiment

Below the utility model will be further described by the specific embodiment.

Referring to figs. 1 through Fig. 4, a kind of crashproof hydrant of the present utility model, comprise a bolt body 1 and a key 2, the flange 11 of bolt body 1 is fixedlyed connected by a special bolt 3 lower than the flange 11 and the intensity of flange 21 with the flange 21 of key 2, be fixed with nut 4 on the special bolt 3, be provided with a planar seal ring 5 between the flange 11 of bolt body 1 and the flange 21 of key 2.The flange 21 of key 2 is provided with crashproof flange spoke 6.The external surface of bolt body 1 is coated with one deck fluorescent paint 7.

A kind of crashproof hydrant of the present utility model because the external surface of bolt body 1 is coated with fluorescent paint 7, can remind the driver to note the existence of hydrant in use, in order to avoid vehicle bumps against hydrant, thereby accomplishes to prevent trouble before it happens.Even the driver does not notice hydrant or because of carelessness bumps against hydrant, because the existence of special bolt 3, special bolt 3 is crashed, and bolt body 1 and key 2 are all harmless, only need change special bolt 3 during reparation and get final product, rehabilitation cost is low, has also avoided a large amount of losses of valuable water resource.

Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
