Abstract
The utility model discloses a connecting device with a sealing ring for sleeve fastening type steel conduit and pipe, comprising a steel conduit and a pipe which is connected with the steel conduit. The connection position of the steel conduit and the pipe is provided with a sealing ring for sealing. The utility model has the advantages of simple structure, low cost and easy production. When in construction, the sealing ring is only sleeved on the connection position of the steel conduit and the pipe, so that the connection position can be sealed well. The utility model provides the cable or wire inside the steel conduit with a safe, dry and clean environment, and effectively overcomes the shortcomings of the prior art.
Description
Technical field
The utility model relates to steel conduit and pipe connecting device, particularly be telescopic steel conduit with tapered adapter and pipe connecting device with sealing ring.
Background technology
Present building trade, in the telescopic steel conduit with tapered adapter pipeline laying engineering, pass the specification requirement of the steel conduit of cable or electric wire, not only to meet national standard " the electric installation of GB/T14823.1-93 conduit specific (special) requirements-metal catheter ", also should meet China Engineering Construction Standardization Association chief editor, be numbered: CECS 120; 2000, name becomes: " construction of telescopic steel conduit with tapered adapter raceway for wiring and control of acceptance ".
As shown in Figure 1, according to afore mentioned rules, between the steel conduit 1 of prior art straight connector 3 and union elbow 4 sockets by having U type groove; When steel conduit 1 enters terminal box 8, answer a hole one pipe, steel conduit 1 is connected with terminal box 8, should adopt pawl type nut to be connected with nipple 5.In order to make cable or electric wire pass steel conduit 1 smoothly; For the good environment of a safety, drying, cleaning being provided for cable or electric wire, the following connected mode of the general employing of prior art: appear for the first time, evenly coat the conducting resinl shutoff at the outer wall of steel conduit 1 termination or at the termination inwall of straight connector 3, union elbow 4, nipple 5 pipe fittings, and then steel conduit 1 termination point casing is connected in straight connector 3, union elbow 4, the nipple 5; Secondly, be tightened on after holding screw on straight connector 3, union elbow 4, the nipple 5 positions, screw holding screw again to screw cap-falling with specific purpose tool.
There is following deficiency in the connected mode of above-mentioned prior art: steel conduit 1 of every connection in the construction, all to evenly coat conducting resinl at its termination outer wall or at straight connector 3, union elbow 4, nipple 5 termination inwalls, if conducting resinl is coated with many, conducting resinl unnecessary during socket steel conduit 1 is extruded, and causes waste; If conducting resinl is coated with few, during socket steel conduit 1 sealing bad, water, mortar are as easy as rolling off a log to infiltrate the steel conduit 1 from the slit that connects, and influences the safe in utilization of cable or electric wire.In addition, it is bigger to be coated with the conducting resinl workload, the construction trouble.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of with seal ring seal be enclosed within steel conduit 1 and with the pipe fitting connector of its socket on telescopic steel conduit with tapered adapter with sealing ring and pipe connecting device.
The technical scheme that solves the problems of the technologies described above is: a kind of telescopic steel conduit with tapered adapter and pipe connecting device with sealing ring, this telescopic steel conduit with tapered adapter with sealing ring comprises with pipe connecting device: steel conduit, the pipe fitting that is connected with steel conduit are provided with sealing ring at steel conduit and its connecting tube interface and seal.
The beneficial effects of the utility model are: the utility model is simple in structure, and cost is low, and is easy to use.Need only the seal ring set in the utility model in the construction at steel conduit and pipe fitting interface, just can well above-mentioned interface be sealed, the good environment that the utility model provides a safety, drying, cleaning for cable in the steel conduit or electric wire effectively overcomes the deficiencies in the prior art.
