Abstract
The invention discloses a welded pipe joint, which comprises a joint body, a connecting pipe, a nut and a sealing ring, wherein the connecting pipe is arranged on one side of the joint body; the nut is sleeved at a joint of the joint body and the connecting pipe; the sealing ring is arranged on the joint body. According to the pipe joint, the connecting pipe is welded on the end part of an oil pipe, and is connected with the joint body by screwing the nut to realize the mounting of the pipe joint; a manufacturing process for the pipe joint is simple, and the pipe joint can stably and reliably work, and is convenient to assemble and disassemble.
Description
Technical field
The present invention relates to a kind of welded stub connection.
Background technique
The installation quality of oil pipe directly affects the working effect of hydraulic system, if install badly, not only can increase the pressure loss, and may make whole system produce the problems such as vibration, noise, cause very large difficulty also can to maintenance and service work, therefore, must pay attention to the installation of oil pipe and pipe fitting.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of preparation process simple, working stability is reliable, simple load and unload pipe joint.
Technological scheme: in order to realize above purpose, a kind of welded stub connection of the present invention, it comprises: fittings body, take over, nut and seal ring, a side of described fittings body is provided with adapter, nut sleeve is located at the joint of fittings body and adapter, and fittings body is provided with seal ring.
Described adapter and oil pipe are connected.
Described adapter and oil pipe are fastening by the mode of welding.
Described fittings body is connected fastening with the oil pipe element by tapered tread.
Beneficial effect: a kind of welded stub connection provided by the invention by an adapter in the oil pipe end welding, and couples together taking over fittings body by screwing nut, realized the installation of pipe joint, this pipe joint manufacturing process is simple, and working stability is reliable, easy accessibility.
The accompanying drawing explanation
Fig. 1 is half sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, a kind of welded stub connection of the present invention, it comprises: fittings body 1, take over 2, nut 3 and seal ring 4.
One side of fittings body 1 is provided with takes over 2, and nut 3 is set in fittings body 1 and takes over 2 joint, and fittings body 1 is provided with seal ring 4.
Take over 2 for one in the welding of the end of oil pipe 5, nut 3 is enclosed within and takes on 2, by screwing nut 3, taking over 2, with fittings body 1, couple together, the other end of fittings body 1 is connected fastening with oil pipe element 6 by tapered tread, saved packing ring, and effectively prevented the generation of leakage of oil, this pipe joint manufacturing process is simple, working stability is reliable, easy accessibility.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence has been done according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
