Abstract
The invention discloses an interface of a fire hose. The interface comprises an interface body as well as a retaining ring and a check ring which are in sleeve connection in the interface body, wherein the outer diameter of the check ring is smaller than the inner diameter of the retaining ring; the check ring comprises a water inlet side wall and a water outlet side wall; and at least one back flow stop plate is arranged on the water outlet side wall of the retaining ring and is in elastic connection with the water outlet side wall. By adopting the technical scheme provided by the invention, the back flow in a fire pipeline can be effectively prevented, and water resources are saved.
Description
Technical field
The present invention relates to the manufacture field of fire-fighting equipment, especially relate to a kind of interface of fire hose.
Background technology
During the situation of the unexpected condition of a fire such as breaking out of fire, fire fighting device plays important effect to controlling fire-fighting dangerous situation in time.By the connection of fire hydrant and fire hose, water is routed to by equipment such as High Pressure Guns the place that the condition of a fire needs, but, once fire hydrant does not herein have water to provide, so need fire fighting truck to carry fire demand water.After being extracted by the fire hose be connected with the water tank on fire hydrant or fire fighting truck, the water resource be deposited in fire hose can reflux and to flow out from the interface of fire hose, causes the waste of water resource greatly.And, the interface of existing fire hose for be all the structure of sealing in connection procedure, for the Utilizing question of the water resource in later stage, the never research and development of the interface of corresponding fire hose.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the interface proposing a kind of fire hose.
Object of the present invention will be achieved by the following technical programs: a kind of interface of fire hose, comprise: interface body, the guard ring being socketed on described interface body inside and back-up ring, the external diameter of described back-up ring is less than the internal diameter of described guard ring, described back-up ring is divided into into water sidewall and water outlet sidewall, the water outlet sidewall of described back-up ring is provided with at least one non-return stream plate, and described non-return stream plate is connected with described water outlet sidewall elastomer.
Preferably, the interface of above-mentioned a kind of fire hose: described non-return stream plate is connected by elastic reseting part with between described water outlet sidewall.
Preferably, the interface of above-mentioned a kind of fire hose: the water inlet sidewall of described back-up ring is provided with the seal member matched with the delivery port of fire hydrant.
Preferably, the interface of above-mentioned a kind of fire hose: described non-return stream plate comprises the first non-return stream plate and the second non-return stream plate, the water outlet sidewall being located at described back-up ring that described first non-return stream plate is relative respectively with described second non-return stream.
Preferably, the interface of above-mentioned a kind of fire hose: superpose between described first non-return stream plate with described second non-return stream plate and arrange.
Preferably, the interface of above-mentioned a kind of fire hose: described non-return stream plate is semicircle, and the radius of described non-return stream plate is greater than the internal diameter of described back-up ring.
Outstanding effect of the present invention is: 1) in the interface of fire hose, be provided with non-return stream plate, has good barrier effect, be conducive to saving water resource for by the water resource after water; 2) non-return stream plate is connected with the water outlet sidewall of back-up ring for by the structure of elastic reseting part, makes to be in open configuration stopping adverse current plate with water, after water inlet, non-return stream sheet reset to closure state, by the fire hose of water resource retention; 3) structure of non-return stream plate is semicircle, and radius is greater than the internal diameter of back-up ring, makes the overlaying structure of non-return stream plate can ensure to stop the backflow of water fully.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of the interface of fire hose.
Detailed description of the invention
As shown in Figure 1, the interface of a kind of fire hose of the present embodiment, comprise: interface body 1, the guard ring 2 being socketed on interface body 1 inside and back-up ring 3, the external diameter of back-up ring 3 is less than the internal diameter of guard ring 2, and back-up ring 3 is divided into into water sidewall 31 and water outlet sidewall 32, the water outlet sidewall 32 of back-up ring 3 is provided with the first non-return stream plate 4 and the second non-return stream plate 5.First non-return stream plate 4 is connected by elastic reseting part with between water outlet sidewall 32 with the second non-return stream plate 5, two non-return stream plates are semicircular structure, and radius is greater than the internal diameter of back-up ring 3, therefore, two non-return stream plates can ensure to be superimposed in closed state, the common backflow stoping current.
In addition, the water inlet sidewall 31 of back-up ring 3 is provided with the seal member matched with the delivery port of fire hydrant, for being tightly connected between the two in the engaged condition, ensures effective utilization of water resource and the pressure of enough water.
When the interface of fire hose is not connected to the interface of fire hydrant or water tank, the first non-return stream plate 4 and the closure state of the second non-return stream plate 5 for being superimposed, closes back-up ring 3 between the two; When being connected to interface, the first non-return stream plate 4 and the second non-return stream plate 5 are rushed to open because being subject to the effect of the pressure of water, and both are in the state of opening, and now current enter fire hose by interface; When fire hose is unloaded from fire hydrant or water tank time, the first non-return stream plate 4 and the second non-return stream plate 5 return to original position, and both are in closure state again, thus stop the backflow of current.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
