Abstract
The utility model relates to a pipe fitting technical field specifically is a trap, examine the elbow including first elbow and the area that links to each other with first elbow, the area is examined the elbow and is included the inspection cover of examining the elbow through threaded connection in the area, the inner chamber of inspection cover center department is equipped with the round platform, and the outer wall cover of round platform is equipped with the seal ring with the round platform adaptation, right -angle trapezoid -shaped is personally submitted in seal ring's rip cutting, seal ring's the biggest internal diameter is greater than the diameter of bottom surface on the round platform, nevertheless is lighter than the diameter of bottom surface under the round platform. The utility model discloses simple structure, the practicality is strong.
Description
Technical field
The utility model relates to pipe fitting technical field, is specially a kind of trap.
Background technology
Traditional trap structure is fixed, when pipeline is arranged in the place relatively narrow and small in this spaces such as rest rooms, pipeline is caused not walk logical, reduce working effect, seal washer simultaneously in conventional trapway is easily out of shape in Long-Time Service process, causes the sealing effectiveness at inspection eye place in trap to reduce.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the water providing a kind of good sealing effect.
For achieving the above object, the utility model provides following technical scheme: a kind of trap, elbow examined by the band comprising the first elbow and be connected with the first elbow, described band inspection elbow comprises the inspection cover be threaded connection at band inspection elbow, the lumen centers place of described inspection cover is provided with round platform, the outer wall of round platform is arranged with the seal washer with round platform adaptation, the rectangular trapezoidal shape of vertical section of described seal washer, the maximum inner diameter of described seal washer is greater than the diameter of round platform upper bottom surface, but is less than the diameter of round platform bottom surface.
Further, described first elbow and band inspection elbow are for removably connecting.
Further, the diameter of round platform bottom surface 0.2mm-0.5mm larger than the maximum inner diameter of seal washer.
Further, the diameter of round platform bottom surface 0.7mm-1mm larger than the diameter of round platform upper bottom surface.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: 1. the first elbow of the present utility model and band inspection elbow are by removably connecting, and according to actual installation needs, first elbow can 360 degree of rotations on band inspection elbow, be welded and fixed finally by sweating welder, make in narrow and small installing space, the comprehensive installation of handled easily personnel, improves operating efficiency.2. the utility model is provided with round platform by the lumen centers place of inspection cover, the outer wall of round platform is arranged with seal washer, and seal washer and round platform are by interference fit, seal washer is reliably fixed, in long-term use procedure, be not easy the phenomenon occurring distortion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the first rotating elbow 90 degree in Fig. 1.
Fig. 3 is the structural representation of inspection cover.
Fig. 4 is the cross-sectional schematic of seal washer.
Detailed description of the invention
With reference to Fig. 1-Fig. 4, the utility model is described further.
A kind of trap, elbow 2 examined by the band comprising the first elbow 1 and be connected with the first elbow 1, described band inspection elbow 2 comprises the inspection cover 3 be threaded connection at band inspection elbow 2, the lumen centers place of described inspection cover 3 is provided with round platform 31, the outer wall of round platform 31 is arranged with the seal washer 32 with round platform 31 adaptation, the rectangular trapezoidal shape of vertical section of described seal washer 32, making seal washer 32 easily be inserted in round platform 31 obtains inner, the maximum inner diameter L of described seal washer 32 is greater than the diameter of round platform 31 upper bottom surface, but is less than the diameter of round platform 31 bottom surface.
Round platform 31 is provided with by the lumen centers place of inspection cover 3, the outer wall of round platform 31 is arranged with seal washer 32, and seal washer 32 and round platform 31 are by interference fit, seal washer 32 is reliably fixed, in long-term use procedure, be not easy the phenomenon occurring distortion.
Further, described first elbow 1 and band inspection elbow 2 are for removably connecting.
First elbow 1 and band inspection elbow 2 are by removably connecting, and according to actual installation needs, the first elbow 1 can 360 degree of rotations on band inspection elbow 2, be welded and fixed finally by sweating welder, make in narrow and small installing space, the comprehensive installation of handled easily personnel, improves operating efficiency.
Further, the diameter of round platform 31 bottom surface 0.2mm-0.5mm larger than the maximum inner diameter L of seal washer 32.
Further, the diameter of round platform 31 bottom surface 0.7mm-1mm larger than the diameter of round platform 31 upper bottom surface.
By the large 0.2mm-0.5mm of maximum inner diameter L of the ratio seal washer 32 of the diameter design of round platform 31 bottom surface, the large 0.7mm-1mm of diameter of ratio round platform 31 upper bottom surface of the diameter design of round platform 31 bottom surface, seal washer 32 is made easily to be inserted in round platform 31, and when seal washer 32 is inserted in the bottom of round platform 31, form interference fit.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
