Description
Technical field
This utility model relates to a kind of waterpipe jointing, particularly to a kind of fire extinguisher canvas hose joint, belongs to pipe fitting manufacturing technology field.
Background technology
Joint, is for connection to a kind of parts of water pipe.Water pipe head can be divided into by occupation mode: external screw thread termination formula water pipe head, bite type water pipe head, self-hard water pipe head.
Waterpipe jointing is applied to the docking of pipeline enclosure and connects.There is following weak point in existing fire extinguisher canvas hose interface: insufficient strength, opening easily occurs when pressure increases in pipe waterpipe jointing, and causes the joint of pipeline to produce drainage.Sealing is poor, and the joint also resulting in pipeline produces drainage.Being necessary the structure of existing pipe waterpipe jointing is improved and innovated, fire extinguisher canvas hose interface typically all carries valvular, when valve uses, and the general Flange joint and threaded of using, also have and use the situation being welded to connect on a small quantity.Using the valve of Flange joint, it is more thick and heavy, thick that the both sides of valve body connect end；Use threaded valve, install cumbersome.The shortcomings such as in a word, it is big that described valve generally exists consumption metal material doses, and machining workload is big, and production cost is high, construction inconvenience, mounting or dismounting trouble.
Utility model content
This utility model provides a kind of fire extinguisher canvas hose joint, and not and sealing difference causes the joint of pipeline to produce drainage can effectively to solve fire extinguisher canvas hose joint strength, and the valve of fire extinguisher canvas hose dismantles inconvenient problem.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one fire extinguisher canvas hose joint, including upper clamp ring, lower clamping and fire extinguisher canvas hose, described upper clamp ring and described lower clamping are combined into close ring and are fixed on outside described fire extinguisher canvas hose, described upper clamp ring and described lower clamping two ends form lug respectively, described lug connects by nut and supporting bolt are fixing, valve hole it is provided with in the middle part of described lower clamping, described valve hole surrounding is provided with the first sealing ring, it is provided with clip in described upper clamp ring and described lower clamping, inside described upper clamp ring, is provided with the second sealing ring.
As a kind of optimal technical scheme of the present utility model, the inwall of described upper clamp ring and described lower clamping is along the embedded groove of the circumferencial direction formation semicircle of described fire extinguisher canvas hose.
As a kind of optimal technical scheme of the present utility model, described first sealing ring and described second sealing ring all use erosion-resisting elastomeric material to make, described first sealing ring and described valve hole are concentric annular, and the width of described second sealing ring matches with the width of described upper clamp ring.
As a kind of optimal technical scheme of the present utility model, the screw thread of the screw both sides of described lug matches with described bolt.
As a kind of optimal technical scheme of the present utility model, described upper clamp ring and described lower clamping all use stainless steel material to make.
This utility model is reached to provide the benefit that: this kind of fire extinguisher canvas hose joint, not and sealing difference causes the joint of pipeline to produce drainage effectively to solve fire extinguisher canvas hose joint strength, the problem of the valve dismounting inconvenience of fire extinguisher canvas hose, upper clamp ring, the second sealing ring and lower clamping act on the sealing so that interface more preferably jointly, valve hole on lower clamping and the second sealing ring make the sealing of valve more preferably simultaneously, each device is fixed by screw bolt and nut simultaneously, dismantle convenient, operate the simplest.
