Abstract
The utility model provides a high-rise high-pressure fire fighting hose coupling which comprises a left connector, a right connector and a clamping hoop. One end of the clamping hoop is clamped on the left connector, and the other end of the clamping hoop is connected with the right connector in a threaded mode. The high-rise high-pressure fire fighting hose coupling is mainly designed according to characteristics of high-rise building extinguishment, and the connecting mode of the left connector and the right connector is changed to overcome the defects that common connectors can be disengaged from buckles easily and low in bearing pressure, and the best extinguishing time can be delayed easily.
Description
Technical field
The utility model relates to fire distinguisher annex, relates to specifically a kind of high-rise high pressure fire fighting hose coupling.
Background technique
Fire hose coupling is as the annex of fire-extinguisher water hose, in fields such as fire-fighting fire extinguishing operations, be widely used, the whole aluminum alloy that adopts of current existing fire hose coupling is made, comprise a left side, right connector, and left, between right connector, adopt conventional buckle to connect, there is following defect in it: on the one hand when practical application, the interface of aluminum alloy material, high voltage performance is poor, at hose coupling, connect in insecure situation, raising along with delivery of water pressure, or in delivery of water process, run into mutation pressure and do the used time, it easily damages, on the other hand, when the joint that buckle connects is applied in tall building fire extinguishing, pressure-bearing is low, very easily thread off, easily affect best fire extinguishing opportunity adversely, moreover, buckle connection sealing is poor.
Therefore, for tall building fire extinguishing feature, propose a kind of high pressure resistantly, the fire hose coupling of good airproof performance becomes the problem that the utility model faces.
Model utility content
Poor for solving existing fire hose coupling barotolerance, the problem that sealing effect is bad, proposes a kind of novel high-rise high pressure fire fighting hose coupling, and it adopts following technological scheme to be achieved:
A high-rise high pressure fire fighting hose coupling, comprises left and right joint and clip, and described clip one end block is on described left joint, and the other end is threaded with right connector.
Further, in order to prevent that clip from coming off, described left joint is provided with a circle steel ring draw-in groove.
In order to strengthen sealing, the end face of described left and right joint arranges respectively seal ring draw-in groove.
In order to improve resistance to pressure and bulk strength, the material of described interface is stainless steel.
Compared with prior art, advantage of the present utility model and good effect are as follows:
The high-rise high pressure fire fighting hose coupling of the utility model is mainly that the feature for tall building fire extinguishing designs, and by changing the Placement of left and right joint, has effectively avoided that ordinary couplings is easily threaded off, pressure-bearing is low, easily affects the best fire extinguishing shortcoming on opportunity adversely.
This enforcement novel overall adopts stainless steel to make, and has the advantages such as high pressure resistant, corrosion-resistant.
Read by reference to the accompanying drawings after embodiment of the present utility model, other features of the present utility model and advantage will become clearer.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model fire hose coupling overall structure schematic diagram;
Fig. 2 is fire hose coupling longitudinal cross-section schematic diagram in Fig. 1;
Fig. 3 is fire hose coupling general assembly structural representation in Fig. 2;
Each is schemed above: 1, left joint; 1-1 steel ring draw-in groove; 1-2, seal ring draw-in groove; 1-3, backstop; 2, right connector; 2-1, seal ring draw-in groove; 3, clip; 4, seal washer; 5, Steel Cable Baffle Ring.
Embodiment
Embodiment one, and referring to figs. 1 to Fig. 3, the utility model fire hose coupling comprises left joint 1, right connector 2, clip 3.It should be noted that the utility model in order to express easily, by the left and right joint of two-part called after of interface, reality can be defined as upper and lower joint as required, and certainly, the title of left and right joint is also interchangeable.
Described left joint 1 end has a circle backstop 1-3, main and the clip 3 of this backstop coordinates, and follow-up introduction seals when guaranteeing that left and right joint connects, on left joint 1 end face, be provided with seal ring draw-in groove 1-2, on right connector 2 end faces, be also provided with equally seal ring draw-in groove 2-1.Described right connector end has outside thread, and main and clip 3 is connected.
In the form of a ring, one end has annular block 3-1 to described clip 3 integral body, on the inwall of the other end, has internal thread.
During installation, with reference to figure 3, in the seal ring draw-in groove 1-2 of left joint end and the seal ring draw-in groove 2-1 of right connector end, install seal ring 4 respectively, sealing circle 4 water-swellables, can play good sealing effect, then clip 3 is passed from the left side of left joint 1, by annular block 3-1 on clip 3 with make clip and left joint difficult drop-off with cooperatively interacting of left joint backstop 1-3, then right connector 2 is threaded on clip 3, screws.
During dismounting, in order to prevent that clip 3 from coming off from left joint 2, the present embodiment is provided with a circle steel ring draw-in groove 1-1 on left joint 2 outer walls, after clip 3 is sleeved on left joint 1, steel ring 5 is stuck in steel ring draw-in groove 1-1, can effectively plays the effect of backstop clip, thereby effectively avoided coming off of clip.
The material of the left and right joint of the present embodiment and clip is stainless steel 304, and its intensity is large, high pressure resistant and good corrosion resistance.
During experiment test, the intensity experiment pressure of the high-rise high pressure fire fighting hose coupling of the utility model is 10Mpa, and water band dropout pulling force is 14.5Mpa, and medium on probation is water, foam mixing liquid.Experimental result surface the utility model fire hose coupling pressure-bearing is high, and difficult drop-off can be applicable to high-rise fire extinguishing completely.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
