Abstract
The utility model relates to fire fighting equipment, in particular to a reel rotating and automatic opening valve on a fire hose reel. The reel rotating and automatic opening valve comprises a connector, a reel valve body, a valve element, a valve rod and an elbow assembly. The reel rotating and automatic opening valve is characterized in that a connector sealing ring is arranged between the reel valve body and the connector, and the reel valve body and the connector are connected through threads and fixed at the threaded connecting position through a set screw; the valve rod is connected into the reel valve body through a valve element spring seat; the outer side of the valve rod is provided with a spring; a part of the valve rod is located in the valve element; a sealing gasket is arranged between the valve rod and the elbow assembly. According to the reel rotating and automatic opening valve, the reel valve body is connected with the connector through the threads, so that replacement is convenient; multiple sealing gaskets are arranged in the reel rotating and automatic opening valve, so water leakage can be effectively prevented, and the reel rotating and automatic opening valve can still have good sealing performance after being used for a long time; steel balls are arranged in the joint between the reel valve body and the elbow assembly, so the reel rotating and automatic opening valve can rotate more flexibly.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, is specifically related to the automatic open valve of rotation of reel on a kind of fire hose reel.
Background technique
The quality of fire-fighting equipment determines fire fighting progress to a great extent, generally all there is inconvenient operation in the rotational automatic open valve of fire hose reel in the market, sealing is not good, easily leak, change the problems such as complicated, in fireman's using process usually because equipment failure, waste regular hour and energy go rescue, thereby affect fire fighting progress, and then cause great personnel and economic loss.
Summary of the invention
Not good for the automatic open valve of rotation of reel in prior art operation inconvenience, sealability, change the problems such as trouble, invented a kind of simple to operate, good seal performance and changed the automatic open valve of rotation of reel easily.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs:
The automatic open valve of a kind of rotation of reel, it comprises joint, reel valve body, spool, valve rod and bend pipe assembly, and its main points are, between described reel valve body and joint, are provided with joint sealing ring, and reel valve body and joint are threaded connection, and in threaded connection place, by screw, fix; Described valve rod is connected to reel valve inner by valve core spring seat, and described valve rod outside is provided with spring, and a valve rod part is arranged in spool, between described valve rod and bend pipe assembly, is provided with sealing gasket.
As preferably, described reel valve body is fixedly connected with by screw with bend pipe assembly, in joint, is provided with steel ball, and described bend pipe assembly outside is provided with groove, is provided with seal ring in groove.
As preferably, described valve rod outside is also provided with nut and rotating screw cap, and described reel valve body outside is provided with aluminium lid, and described aluminium lid is fixed by jump ring.
