Abstract
A movable joint comprises a joint main body and locking connecting nuts. Outer connecting threads are arranged at two ends of the joint main body, inner connecting threads are arranged in the locking connecting nuts, the locking connecting nuts are meshed with the two ends of the joint main body, a groove is formed between the inner connecting threads of one locking connecting nut and the end face of the locking connecting nut, and a sealing ring is arranged in the groove. The movable joint is convenient to install and maintain, saves time and labor and is suitable for various pipelines and easy to detach from and install on the pipelines. Due to the fact that the number of turns of inwards or outwards threads of the joint is increased, the pipeline connection is firm.
Description
Technical field
The utility model relates to a kind of water pipe adapter, especially a kind of union that is installed on the water channel pipe fitting.
Background technique
At present, Placement connects as bolt or hot melt between the pipeline that generally uses, and connects for bolt, when mounted, need will tighten between two connecting tubes or connecting tube and the interface by rotation.When waterpipe connects, joint at each root pipe is connected by flange or joint, existing galvanized metal pipe joint is inipple mostly, connect for hot melt, mainly be for the connection between the plastic tube, when mounted, need two plastic tubes be linked together by the end of heating of plastic pipe.Existing blanching welding need move on to the scene with hot melt equipment, if by operation on the floor or road, hot melt equipment is moved to the job site will be pretty troublesome.
The model utility content
The purpose of this utility model is existing defective in order to solve in the prior art water pipe and to connect, and provides a kind of and is convenient to the connection of two water pipes and is connected firmly, install save time, labour-saving water pipe union.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of union, comprise adapter body and locking attaching nut, the two ends of described adapter body are provided with outer connecting thread, described locking attaching nut is provided with interior connecting thread, the locking attaching nut is meshed with the two ends of adapter body, as improvement of the present utility model, be provided with groove between described locking attaching nut's interior connecting thread and locking attaching nut's the end face, in this groove, be provided with seal ring.
Above-mentioned a kind of union, described groove circumferentially extends along locking attaching nut's internal surface.
Above-mentioned a kind of union, the groove face of described groove are the smooth butt conical surface.
Above-mentioned a kind of union, described seal ring are the O RunddichtringO.
Above-mentioned a kind of union, described locking attaching nut's quantity are 2.
The beneficial effects of the utility model are: installation, maintenance is convenient, saves time, laborsaving, is applicable to be installed in the various pipelines, is contained on the pipeline easy to assemble. because the number of turns of the inside or outside screw thread of joint has increase, institute is so that pipeline connects more firm.
Description of drawings
Fig. 1 is structural representation of the present utility model
Fig. 2 is sectional view of the present utility model
Embodiment
Further understand and be familiar with for making structure characteristic of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 and Figure 2, a kind of union, comprise adapter body 1 and locking attaching nut 2, the two ends of adapter body are provided with outer connecting thread, locking attaching nut 2 is provided with interior connecting thread, and locking attaching nut 2 is meshed with the two ends of adapter body 1, as improvement of the present utility model, be provided with groove 3 between locking attaching nut's 2 interior connecting thread and locking attaching nut's the end face, in this groove 3, be provided with seal ring 4.
Groove 3 circumferentially extends along locking attaching nut's 2 internal surface, and the groove face of groove 3 is the smooth butt conical surface; Seal ring 4 is the O RunddichtringO.
Locking attaching nut's 2 quantity is 2.
When two pipelines need connect, outside thread by two pipelines is meshed with two locking attaching nuts' 2 interior connecting threads respectively can reach the effect of connection, wherein, sealing effect has been played in the joint of 4 pairs of unions of seal ring and pipeline, when the pipe in the pipeline and other accessory are changed, must not cut or mobile pipe position, only need unscrew locking attaching nut 2, make pipeline separate with union and get final product.
This union installation, maintenance is convenient, saves time, laborsaving, is applicable to be installed in the various pipelines, is contained on the pipeline easy to assemble. because the number of turns of the inside or outside screw thread of joint has increase, institute is so that pipeline connects more firm.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
