Abstract
The utility model discloses a hydraulic engineering conduit coupling, including the inside casing that link up, be provided with the control valve on the casing, all be provided with ring groove on the intake end and the play water end (W. E. ) of casing, be provided with positioner on the casing, positioner and ring groove use the cooperation, be provided with seal ring in the ring groove. The advantage is: the utility model has the advantages of simple structure, the casing intake the end and go out the water end (W. E. ) on ring groove can carry out the joint with the pipeline, rethread positioner fixes a position the pipeline, compares its emergence that can effectively prevent the drainage of present structure like this, improves the permanence of using.
Description
Technical field
The utility model belongs to hydraulic engineering pipe fittings technical field, especially relates to a kind of hydraulic engineering pipe joint.
Background technique
At present, in the work progress of hydraulic engineering, building of pipeline is a ring of outbalance, and pipe joint is as the important accessory of connecting tube, and it can play the effect be fastenedly connected.Existing pipe joint can only play general connection function mostly, and in use the junction of itself and pipeline just adopts general seal ring to seal, and this vibrational power flow easily produces water leakage phenomenon after a long time use, thus impact is normal uses; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of hydraulic engineering pipe joint, and it has structure simply and the feature of water leakage phenomenon also can not occur after a long time use.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of hydraulic engineering pipe joint, comprises the housing of internal run-through, and described housing is provided with control valve; The feed-water end of described housing and waterexit end are provided with annular slot, described housing is provided with positioning device, described positioning device and annular slot collaboration; Seal washer is provided with in described annular slot.
Described positioning device comprises positioning screw and rotary nut, and described positioning screw is screwed onto on the screw of housing, and described screw is communicated with annular slot, and described rotary nut is fixedly installed on the end of positioning screw.
The feed-water end of described housing and waterexit end are provided with inclined-plane.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, annular slot on housing feed-water end and waterexit end can carry out clamping with pipeline, by positioning device, pipeline is positioned again, it effectively can prevent the generation of water leakage phenomenon to compare existing structure like this, improves the permanence used.
Accompanying drawing explanation
Fig. 1 is plane structure schematic diagram of the present utility model.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, as shown in Figure 1: a kind of hydraulic engineering pipe joint, comprises housing 10 and the positioning device of internal run-through, housing 10 in the middle part of be provided with control valve 11, control valve 11 can control the flow of pipeline water flow inside.The end of housing 10 is provided with feed-water end and waterexit end, and feed-water end and waterexit end are provided with annular slot 12, is provided with seal washer 13 in annular slot 12; Positioning device comprises positioning screw 20 and rotary nut 21, and positioning screw 20 is screwed onto on the screw of housing 10, and screw is communicated with annular slot 12, and rotary nut 21 is fixedly installed on the end of positioning screw 20; In use, by pipeline to be connected in annular slot 12 and to abut with the end face of seal washer 13, rotate the end face that rotary nut 21 allows positioning screw 20 be connected to pipeline again and play location fastening effect, such pipeline in use effectively can avoid the generation of water leakage phenomenon, extends life cycle.The feed-water end stating housing 10 and waterexit end are provided with inclined-plane 14, and the end on inclined-plane 14 can abut with inner-walls of duct, is convenient to inflow and the outflow of current like this.
