Description
Technical Field
The utility model relates to a water pipe head field especially relates to a high pressure water resistant pipe head.
Background
In high-pressure water mist fire extinguishing system, because the shape restriction of tubular product size and mounted position, make fire water pipe have a plurality of links, and, because the operating pressure that fire water pipe fluid was carried exceeds more than 10Mpa, but, pipe fitting is pressed to traditional thin wall card, only use the fluid transport environment at 1.6Mpa operating pressure, can not make fire water pipe link lug connection, need use thick-walled pipe to pass through the welding mode and connect, it is comparatively inconvenient to lead to the installation of fire water pipe, consequently, need not a kind to weld alright connect and high pressure resistant water pipe head urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the following problems existing in the prior art: however, the conventional thin-wall clamping and pressing pipe fitting only uses a fluid conveying environment at the working pressure of 1.6Mpa, and cannot directly connect the connecting ends of the fire-fighting water pipes, so that the fire-fighting water pipes are inconvenient to install due to the fact that the thick-wall pipes are required to be connected in a welding mode.
For solving the problem that prior art exists, the utility model provides a high pressure water resistant pipe joint, the connecting pipe comprises a connecting pipe, the both ends of connecting pipe all are provided with the sleeve pipe, two the sheathed tube inboard all is provided with O shape circle, the sleeve pipe with the clearance has between the connecting pipe.
Preferably, both ends of the sleeve are straight sections, the diameter of one end of the sleeve is larger than that of the other end of the sleeve, the joint of the two ends of the sleeve is in a large-small head shape, and the structure is used for forming a circular gap between one end of the sleeve and the connecting pipe.
Preferably, the one end internal diameter of sheathed tube is greater than the external diameter of connecting pipe, sheathed tube other end internal diameter and the external diameter adaptation of connecting pipe, this structure is used for making sheathed tube other end and connecting pipe be connected, and makes behind the fire water pipe sheathed tube other end be sealed form.
Preferably, the one end of sleeve pipe just is close to the edge and is provided with the annular arch of semicircle from inside to outside, the protruding inboard of sleeve pipe is provided with O shape circle, and this structure is used for making to seal between sleeve pipe and the fire hose, places and leaks.
Preferably, the diameter of the O-shaped ring is matched with the size of the inner side of the bulge of the sleeve, the inner diameter of the O-shaped ring is smaller than that of one end of the sleeve, and the O-shaped ring is clamped on the inner side of the bulge of the sleeve.
Preferably, the inside diameter of the O-ring is larger than the outside diameter of the connection pipe, and the structure is used for inserting the fire hose into the gap between the sleeve and the connection pipe, and the fire hose extrudes the O-ring to seal the gap between the sleeve and the fire hose.
Preferably, the shape of the connecting pipe is a bent pipe and a straight pipe, and the structure is used for enabling the application range of the joint to be wide.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses an insert the fire control tubular product to the clearance of sleeve pipe and connecting pipe in to keep silent through the compression tool and make sheathed tube one end tighten up the deformation, make the fire control water pipe fix between sleeve pipe and connecting pipe, make the joint reach 10 Mpa's operating pressure environment demand, make the fire control tubular product need not the thick wall pipe of welding alright installation, it is comparatively convenient to make the installation of fire control tubular product.
