Description
Technical field
The utility model relates to construction engineering technical field, particularly relates to a kind of excavation drinking-water pipe joint.
Background technology
Along with the continuous construction of China's construction-engineering project, security issues become increasingly urgent for building, in excavation of foundation pit, seepage flow is particularly serious to its security implication, permeation fluid mechanics has extensively caused the attention of researcher, Chinese scholars is to this has been more research, achieve certain achievement in research, cover multiple technological layer, but due to the seepage theory of classics be based on continuous medium hypothesis, and numerous case histories and scientific research show, Seepage of Rock Masses and seepage through soil mass are essentially different.Current various flow model in porous media does not mostly reach the real stage solving engineering problem, all needs to do further deeply concrete research to the identification of theoretical model, constitutive relation, calculating parameter.Seepage of Rock Masses is a quite complicated process; this qualitative difference is there is in the seepage flow in crack rock and traditional Porous Media in mechanism; this difference main manifestations is the non-homogeneity that crack rock exists on various yardstick; therefore; be difficult to the precipitation problem fundamentally solved in excavation of foundation pit; need to adopt water pump etc. to carry out water outlet; foundation ditch is usually darker; single flexible pipe is oversize can exist the more difficult problem of water outlet usually; when not drawing water; wish to carry out water shutoff, prevent foreign material from entering water pipe.
Utility model content
The purpose of this utility model is for above weak point, provides a kind of excavation drinking-water pipe joint, prevents foreign material from entering water pipe.
The scheme that the utility model technical solution problem adopts is: a kind of excavation drinking-water pipe joint, comprise a male joint and a female joint, outside described male joint one end, perimembranous is provided with external screw thread, and described female joint one tip inside perimembranous is provided with the internal thread matched with described external screw thread; Also comprise the rubber ring that is O type, described male joint is threaded with described female joint through described rubber ring, and described rubber ring sleeve is located between internal thread and external screw thread.
Further, on described internal thread and external screw thread is corresponding respectively offers one for the groove in the form of a ring of accommodating described rubber ring, the degree of depth of described groove is 1/2 of rubber ring diameter of section.
Further, the outer circumferential side of described male joint and female joint is interval with several circular protrusions along its length.
The utility model provides another kind of excavation drinking-water pipe joint, comprises a male joint and a female joint, and outside described male joint one end, perimembranous is provided with external screw thread, and described female joint one end inner peripheral is provided with the internal thread matched with described external screw thread; Also comprise a rubber sheet gasket in the form of annular discs, the diameter of described rubber sheet gasket is greater than the internal diameter of described female joint, and described rubber sheet gasket is pressed in described female joint through described male joint, and to be threaded compression through described male joint and female joint.
Further, the outer circumferential side of described male joint and female joint is interval with several circular protrusions along its length.
Compared with prior art, the utility model has following beneficial effect: by being located between male joint and female joint by O type rubber ring sleeve, and closely cooperating with described male joint and female joint connecting end portion, playing good sealing function, prevents infiltration.Another kind of drinking-water pipe joint of the present utility model, described rubber sheet gasket is pressed in described female joint through described male joint, and to be threaded compression through described male joint and female joint, realizes effectively arrive sealing and intercepting water.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model patent is further illustrated.
Fig. 1 is the structural representation of a kind of excavation drinking-water pipe joint of the utility model embodiment;
Fig. 2 is the structural representation of the another kind of excavation drinking-water pipe joint of the utility model embodiment;
In figure: 1-male joint; 2-female joint; 3-rubber ring; 4-groove; 5-rubber sheet gasket; 6-circular protrusion.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model provides a kind of embodiment to be: a kind of excavation drinking-water pipe joint, comprise male joint 1 and a female joint 2, described male joint 1 one end outer circumferential side is provided with external screw thread, and inner circumferential side, described female joint 2 one end is provided with the internal thread matched with described external screw thread; Also comprise the rubber ring 3 that is O type, described male joint 1 is threaded with described female joint through described rubber ring, and described rubber ring sleeve is located between internal thread and external screw thread.
From the foregoing, by rubber ring 3 is sheathed between male joint 1 and female joint 2, and closely cooperate with described male joint 1 and female joint 2 connecting end portion, play good sealing function, prevent infiltration.
In the present embodiment, on described internal thread and external screw thread is corresponding respectively offers one for the groove 4 in the form of a ring of accommodating described rubber ring 3, the degree of depth of described groove 4 is 1/2 of rubber ring 3 diameter of section d1.Made by described groove 4 that rubber ring 3 is better must be placed within male joint 1 and female joint 2, realize better diversion.
In the present embodiment, the outer circumferential side of described male joint 1 and female joint 2 is interval with several circular protrusions 6 along its length.Described circular protrusion 6 is not only convenient to the installation of suction hose, and can play the sealing effectiveness between suction hose and joint.
Another embodiment of the present utility model provides a kind of excavation drinking-water pipe joint, comprise male joint 1 and a female joint 2, described male joint 1 one end outer circumferential side is provided with external screw thread, and inner circumferential side, described female joint 2 one end is provided with the internal thread matched with described external screw thread; Also comprise a rubber sheet gasket 5 in the form of annular discs, the diameter d 2 of described rubber sheet gasket 5 is greater than the internal diameter d3 of described female joint 2, described rubber sheet gasket 5 is pressed in described female joint 2 through described male joint 1, and to be threaded compression through described male joint 1 and female joint 2, to realize effectively arrive and seal and intercept water.
In another embodiment, the outer circumferential side of described male joint 1 and female joint 2 is interval with several circular protrusions 6 along its length.Described circular protrusion 6 is not only convenient to the installation of flexible pipe, and can play the sealing effectiveness between flexible pipe and joint.
In sum, two kinds of excavation drinking-water pipe joints that the utility model provides, realize diversion and the function that intercepts water respectively, and structure is simple, workable.
