Abstract
The utility model relates to a direct insertion type loose joint water meter used on a hydraulic pipeline. One end of the utility model is composed of a plug screw, a sealing ring and an adapter sleeve, and the other end of the utility model is composed of a screw cap, a sealing ring and an adapter sleeve. When the utility model is installed, a pipe is directly inserted into the water meter, and then, the plug screw and the screw cap are respectively screwed down. The bearing sealing pressure of a connection part is greater than 5MPa, and the axial bearing pulling force is greater than 13000N.
Description
The utility model relates to the water meter on a kind of hydraulic pipeline.
At present, the water meter that is adopted on the hydraulic pipeline all is to adopt one section copper pipe to be connected with pipeline with a copper nut.This not only installs trouble, and consumes more copper material, and cost is increased.Proposed province's copper speed water receiving table for this reason in the ZL92234318.7 patent, economized copper 54%, cost reduces by 20%, and installation efficiency improves more than 10 times.But this patent also has the following disadvantages, and is darker in the pipe insertion water gauge body when first is installed, and is difficult to form loose joint, also needs articulation is installed in addition in pipeline, increased cost.It two is that switching performance is poor, because just rely on the extruding rubber seal to finish the fastening of pipe and sealing, bears sealing load and has only 1MPa.
The purpose of this utility model is that a kind of direct insertion connecting water meter will be provided, and it can overcome existing above-mentioned weak point in the prior art effectively.
The purpose of this utility model realizes by structure shown in the drawings.One end of water gauge body is to belong to plug screw type structure, and O-ring seal is arranged in water gauge body, and the outside is furnished with a fixing sleeve, and the conical surface of fixing sleeve matches with the plug screw conical surface of its outside.Because adopt plug screw type structure, this end of water gauge body just is a female screw, polygon just can be made in its outside, such as octagon.When the two ends pipe was installed, this octagon just can play the fixedly effect of spanner.The other end of water gauge body just can adopt the nut type structure like this, and the O-ring seal sub-fraction is positioned at the end face chamfering of this end, and all the other major parts are in the water gauge body outside.The O-ring seal outside is furnished with a fixing sleeve equally, and the conical surface of fixing sleeve matches with the nut conical surface of its outside.During installation, the neat mutually or pipe end of pipe end face and O-ring seal end face exceeds a bit slightly, thereby forms butt-end packing, makes water meter have the loose joint function with this.The fixing sleeve that is adopted in the structure is the taper split ring of being made by steel, and its inside surface has annular tooth.During installation, turn plug screw and nut respectively, they then promote fixing sleeve and come the crush seal circle, make it to play the effect of sealing pipe.When further tightening plug screw and nut, fixing sleeve will slide along the conical surface of plug screw with matching and nut, thereby fixing sleeve produces radial shrinkage.Meanwhile the annular tooth of its inside surface is carved into outer tube surface, and then pipe and water meter are fixed together securely, thereby makes the junction bear sealing load greater than 5MPa, axially bears pulling force greater than 13000 newton.
The concrete structure of utility model is provided by accompanying drawing.
Accompanying drawing is the sectional view according to the direct insertion connecting water meter that the utility model proposes.
During installation,, successively plug screw (4), fixing sleeve (3) and O-ring seal (2) are enclosed within on the pipe (6), are inserted into then in the end with female screw of water gauge body (1), tighten plug screw (4) according to orientation shown in the drawings.Successively nut (5), fixing sleeve (3) and O-ring seal (2) are enclosed within on another root pipe (6) again, place it in the other end of water gauge body (1) then, again tightening nuts (5).
Claims (1)
