Abstract
The utility model discloses a pressure-bearing vertical pipe access opening structure used for building internal drainage. At present, the commonly used vertical pipe access opening is a non-pressure-bearing pipe fitting, has poor sealing performance and can hardly bear pressure, and causes water leakage when in heavy storm or a discharge pipe is blocked. The pressure-bearing vertical pipe access opening structure is characterized in that the access opening is connected with a cover, and a bush is arranged in the access opening and sheathed with a sealing ring which is positioned between the outer wall of the bush and the inner wall of the access opening. In the pressure-bearing vertical pipe access opening structure, the bush is arranged at the access opening and provided with the sealing ring which is clamped between the outer wall of the bush and the inner wall of the access opening, thus leading the access opening to have better sealing effect and be capable of bearing larger pressure.
Description
Technical field
The utility model relates to the pipe fitting of indoor rainwater, effluent discharge, row's pressure-bearing standpipe inspection hole structure in the rainwater in especially a kind of building.
Background technology
Carry out clear and coherent for convenient to drainage pipe, the general standpipe inspection hole that adopts is as clear and coherent inlet on the drainage pipe, standpipe inspection hole commonly used at present is non-pressure-bearing pipe fitting, reach sealing effectiveness by crush seal circle after tightening lid, because sealing ring and lid and inspection hole mouth are big along contact surface, sealing effectiveness is very poor, and almost can not bear pressure, when being used for storm-water system, do not have drainage generally speaking, when heavy rain or discharge pipe obstruction, can cause the inspection hole place to leak, often bring a lot of inconvenience and economic loss to the user.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of pressure-bearing standpipe inspection hole structure of good sealing effect is provided, and leaks to avoid the inspection hole place.
For this reason, the utility model adopts following technical scheme: pressure-bearing standpipe inspection hole structure, comprise standpipe and the inspection hole of opening in standpipe one side, it is characterized in that described inspection hole place connects a lid, be provided with a lining in the inspection hole, be with sealing ring on the described lining, sealing ring is between lining outer wall and inspection hole inwall.
The utility model makes inspection hole have the better seal effect by sealing ring; Owing to can not deviate from when lining and sealing ring are subjected to big pressure, the sealing effectiveness when making inspection hole bear big pressure is still better.
Above-mentioned pressure-bearing standpipe inspection hole structure has annular groove on the outer wall of lining, and described sealing ring places in the described annular groove, and annular groove positions sealing ring.
Above-mentioned pressure-bearing standpipe inspection hole structure, the outer end of lining is sandwiched between the inwall of the end face of inspection hole and lid, lid is connected on the inspection hole by screw, can not deviate from the time of effectively guaranteeing the lining pressurized, guarantees bonding strength by increasing form of thread size and effective length.
Above-mentioned pressure-bearing standpipe inspection hole structure, the inwall of lid forms a boss, forms the step of a circle and boss edge mate on the lining, by the cooperate bearing capacity that further improve inspection hole of boss with step.
Above-mentioned pressure-bearing standpipe inspection hole structure, sealing ring has more than two, is the O type, further the enhanced leaktightness effect.
The utility model is on the basis of existing non-pressure-bearing standpipe inspection hole, adorn a lining at the inspection hole place, adorn sealing ring on the lining, sealing ring is sandwiched between lining outer wall and the inspection hole inwall, thereby makes inspection hole have the better seal effect and can bear bigger pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Standpipe inspection hole structure as shown in Figure 1, a side of standpipe 1 has inspection hole 5, is provided with lining 3 in the inspection hole 5, have an annular groove on the outer wall of lining 3, annular groove is built-in with O RunddichtringO 4 one, and sealing ring 4 is sandwiched between lining 3 outer walls and inspection hole 5 inwalls, plays sealing function.Lid 2 is connected on the inspection hole 5 by screw, and the outer end of lining 3 is sandwiched between the inwall of the end face of inspection hole 5 and lid 2.The inwall of lid 2 forms a boss, forms the step of a circle and boss edge mate on the lining 3.
