This novel can carry out the sealed detection of pressure nature before throwing into the operation behind the pipe connection, have simple to operate swift, two rubber ring leakproofness better, the higher characteristics of pipeline operation security.
Description
Technical Field
The utility model relates to a hold plug-in type pipe fitting, especially can supply sealed socket joint formula plastic tubular product or the compound tubular product of plastic that the double rubber ring that detects.
Background
Because current plastic conduit rubber ring can't ensure sealed intact when erection joint, need fill water in the pipeline and carry out hydrostatic test after the installation is accomplished, it is sealed intact to inspect the rubber ring, wastes a large amount of water and finds after the whole pipeline is settled that it is very difficult to leak and change.
Chinese patent documents are disclosed as follows:
the first document is: a PVC plastic pipe set and its forming equipment (CN201711477886.9) has a socket on one end of straight pipe and the internal diameter of socket is equal to the external diameter of straight pipe. The connecting pipe fittings are sealed by tight fit. The problem that air tightness is not high exists between the socket pipe fittings.
Document two: a multi-purpose rubber ring connector for plastic pipe (CN201520305603.2) is composed of a high-strength elastic rubber ring between the female end and female end.
Neither of the two methods solves the problem of seal detection between socket pipe fittings.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a good, sealed socket joint formula plastic pipe fitting that detects of just being convenient for of gas tightness.
The purpose of the utility model is realized like this: a socket type plastic pipe fitting with a sealing detection function is characterized in that one end of a straight pipe or a bent pipe is provided with a socket, the other end of the straight pipe or the bent pipe is provided with a plug, and the socket is formed by connecting an outwards expanded bell mouth section and a straight section end to end; an inner rubber ring and an outer rubber ring are arranged between the socket and the plug-in connector which are mutually plugged together, the inner rubber ring and the outer rubber ring) are respectively embedded and pressed in the grooves on the inner wall of the socket and the outer wall of the plug-in connector, and a water or gas inlet and a water or gas outlet which are used for detecting the sealing condition are arranged on the corresponding socket between the inner rubber ring and the outer rubber ring; the water or gas inlet and the water or gas outlet are threaded holes convenient for screwing in the bolt seal.
The length of the bell and spigot is 10cm-80 cm.
The straight pipe or the bent pipe is a PVC plastic pipe.
Another object of the utility model is to provide a socket joint formula plastic pipe fitting that the gas tightness is good, and be convenient for the atmospheric pressure seal detects.
One end of the straight pipe or the bent pipe is provided with a bell socket, the other end of the straight pipe or the bent pipe is provided with a plug, and the bell socket is formed by connecting a flared bell mouth section and a straight section end to end which are expanded outwards; an inner rubber ring and an outer rubber ring are arranged between the socket and the plug which are mutually plugged together, the inner rubber ring and the outer rubber ring are respectively embedded and pressed in the grooves on the inner wall of the socket and the outer wall of the plug, and a valve cock used for detecting the air pressure sealing condition is arranged on the corresponding socket between the inner rubber ring and the outer rubber ring.
The length of the bell and spigot is 10cm-80 cm.
The straight pipe or the bent pipe is a PVC plastic pipe.
Compared with the prior art, the utility model has the following characteristics and advantages:
1. two rubber rings are arranged in the socket joint to form double sealing, and the sealing performance is better than that of the existing rubber ring.
2. Sealing detection is facilitated.
After the pipeline installation connection is completed, the sealing space between the inner rubber ring and the outer rubber ring is sealed and detected by using water or air before use.
Form sealed space between two rubber rings, from a screw hole logical water or gas, another screw hole exhaust, this sealed space is intake or is intake full back, adopts the bolt screw in another screw hole to form sealedly, continues to intake again or admit air and pressurize the detection to reach required sealed degree. After the test is finished, water in the sealed space is emptied or exhausted to be close to the atmospheric pressure, and finally, a bolt is screwed into the threaded hole for water or gas inlet and is sealed in a sealing mode.
