Background technology
Fire hose reel is to make extinguishing chemical with water, can during rapid unwinding hoses the fire extinguishing appliance of spray fire extinguishing agent, it is typically mounted in indoor fire hydrant case, novel indoor permanent fire protection system, it is adaptable to the material such as A class carbohydrate such as papery of putting out a fire to save life and property, wooden and ramie cotton fabric from the beginning of fire.The connector being currently used for connecting fire hose and fire hydrant needs the joint connected with fire hydrant, the ball valve controlling folding and the three kinds of parts of joint connected with fire hose, not only manufacturing cost is high, and install the most extremely onerous, add the waste of easily-consumed products during installation.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of horizontal fire hose connects valve, and it can effectively solve the problem that existing fire hose connector is relatively costly, installs trouble and the problem causing easily-consumed products to waste.
This utility model be the technical scheme is that a kind of horizontal fire hose connects valve, including a fire hydrant connector portions connected with fire hydrant, hose coupling portion that one is connected with fire hose and a ball valve portion, described fire hydrant connector portions, ball valve portion and hose coupling portion three part are one-body molded, the axis in described fire hydrant connector portions and described hose coupling portion overlaps, and described ball valve portion is positioned between described fire hydrant connector portions and described hose coupling portion, it is provided with the switch knob for this ball valve portion of closure or openness in described ball valve portion, the medial wall in described hose coupling portion is provided with female thread, this hose coupling portion female thread connects matched pressure relief assembly.
As preferably, described pressure relief assembly includes reducing pressure housing and being arranged on the fixing back-up ring of decompression enclosure interior and movable back-up ring, described decompression housing is the tube structure that left and right communicates, and on its lateral wall, it is provided with the external screw thread that the female thread with medial wall, described hose coupling portion matches, be provided with between described fixing back-up ring and movable back-up ring on relief spring, described fixing back-up ring and described movable back-up ring being provided with that the stream that supplies water passes through cross water through hole.
As preferably, described fixing back-up ring is crossed water through hole excessively on water through hole and described movable back-up ring and shifts to install.
The beneficial effects of the utility model are: owing to this utility model uses said structure, by fire hydrant connector portions, ball valve portion and the three in one molding of hose coupling portion, eliminate the step in the past needing that three part sealing rotaries are connected on a piece, save the set-up time, decrease cost of labor, add reliability, the waste of easily-consumed products is installed when decreasing installation, it is greatly saved cost of manufacture and the maintenance cost of this connection valve, also saves installing space simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, fire hydrant connector portions；2, hose coupling portion；3, ball valve portion；31, switch knob；41, decompression housing；42, fixing back-up ring；43, movable back-up ring；44, relief spring；45, water through hole is crossed.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments this utility model is described in further detail.
As shown in Figure 1, a kind of horizontal fire hose connects valve, including a fire hydrant connector portions 1 connected with fire hydrant, hose coupling portion 2 that one is connected with fire hose and a ball valve portion 3, described fire hydrant connector portions 1, ball valve portion 3 and hose coupling portion 2 three part are one-body molded, the axis in described fire hydrant connector portions 1 and described hose coupling portion 2 overlaps, and described ball valve portion 3 is between described fire hydrant connector portions 1 and described hose coupling portion 2, the switch knob 31 for this ball valve portion 3 of closure or openness it is provided with in described ball valve portion 3, the medial wall in described hose coupling portion 2 is provided with female thread, this hose coupling portion 2 female thread connects matched pressure relief assembly.
As preferably, described pressure relief assembly includes reducing pressure housing 41 and being arranged on the decompression fixing back-up ring 42 within housing 41 and movable back-up ring 43, the tube structure that described decompression housing 41 communicates for left and right, and on its lateral wall, it is provided with the external screw thread that the female thread with medial wall, described hose coupling portion 2 matches, it is provided with relief spring 44 between described fixing back-up ring 42 and movable back-up ring 43, being provided with, on described fixing back-up ring 42 and described movable back-up ring 43, the water through hole 45 excessively that the stream that supplies water passes through, cross water through hole 45 excessively on water through hole 45 and described movable back-up ring 43 on described fixing back-up ring 42 to shift to install.The setting of pressure relief assembly make current by time according to practical situation, hydraulic pressure can be adjusted, it is to avoid hydraulic pressure is excessive causes damage to fire-fighting equipment；And pressure relief assembly is threadedly attached in hose coupling portion 2, it is simple to user Dismountable as required uses.
Owing to this utility model uses said structure, by fire hydrant connector portions 1, ball valve portion 3 and hose coupling portion 2 three in one molding, eliminate the step in the past needing that three part sealing rotaries are connected on a piece, save the set-up time, decrease cost of labor, add reliability, the waste of easily-consumed products is installed when decreasing installation, it is greatly saved cost of manufacture and the maintenance cost of this connection valve, also saves installing space simultaneously.
