Description

For the detachable wire outlet hole Sealing of combustion gas test terminal
Technical field
The invention belongs to explosion-proof field, particularly relate to a kind of detachable wire outlet hole Sealing for combustion gas test terminal.
Background technique
Combustion gas test terminal is for sending to far-end, and the signal of reception far-end, be arranged on gas monitoring station, it is connected with the various monitoring instruments in monitoring station, because near gas pipeline, so pay much attention to explosion-proof, special line place, if gas leakage enters in the housing of test terminal, easily there is explosive incident, so occur that hole place need to seal setting, existing a shoulder hole is set on casing, aperture inwardly, rubber ring is set in macropore, then with a screw column compressing rubber ring, cable is through shoulder hole, rubber ring and screw column, screw column is threaded onto in macropore, screw rear compressing rubber ring, thereby make rubber ring laterally oppress cable, ensure sealing, but in use for some time, internal thread in macropore there will be the problem such as crumble, screw column is twisted not tight, be difficult to ensure sealing, cause test terminal casing unavailable, cost is increased.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, a kind of detachable wire outlet hole Sealing for combustion gas test terminal is provided, solve in the wire outlet hole of existing combustion gas test terminal, easily damage for the internal thread sealing, have influence on the defect of sealing.
The present invention is achieved through the following technical solutions: for the detachable wire outlet hole Sealing of combustion gas test terminal, comprise the wire outlet hole that runs through wall box, be arranged on the Sealing in wire outlet hole outside, described Sealing is cylindric, its center is provided with a perforation, and perforation is coaxial with wire outlet hole, the diameter of perforation is greater than the diameter of wire outlet hole, rubber ring and compressing rotating part are set in perforation, compressing rotating part is threaded in perforation, compressing rotating part is provided with the coaxial aperture coordinating with wire outlet hole, the external diameter of rubber ring is consistent with the diameter of perforation, the internal diameter of rubber ring is consistent with the diameter of wire outlet hole, on the periphery wall of Sealing, be provided with along limit, along tapped hole is evenly set on limit, Sealing is by being arranged on casing along limit.In this device, wire outlet hole is for the turnover of cable, cable and wire outlet hole should be supporting, the diameter of cable equals the diameter of wire outlet hole, coaxial aperture is consistent with compressing rotating part axis, when use, cable is through wire outlet hole, Sealing, rubber ring and compressing rotating part, rubber ring is positioned at perforation, rotation compressing rotating part, rubber ring is oppressed, make the rubber ring horizontal expansion of having to, thereby cable is carried out to a circle compressing, ensured sealing, and while needing high leak tightness, rubber ring thickness is increased, and rubber ring oppressive force is also increased, thereby strengthen sealing, and the very convenient replacing of rubber ring in this device, and this device is in the time that damaging appears in the internal thread of Sealing, can take off Sealing, again change one, very convenient, and gap between Sealing and casing have rubber ring every the sealing that will not have influence on device.
Further, above-mentioned compressing rotating part is a hex head bolt that is provided with coaxial aperture, can tighten compressing rotating part with pliers, ensures sealing.
Further, the length of threaded end and the length of perforation of above-mentioned compressing rotating part coordinate, and the hexagonal end of compressing rotating part is that rubber is made, when threaded end is urged to rubber ring, hexagonal end also can be urged to aperture, thereby makes the also horizontal expansion of hexagonal end, cable is oppressed, carry out first layer sealing.
Further, the periphery of above-mentioned hexagonal end is covered with the raised line having vertically, because be that rubber is made, so with the bad rotation of pliers, so raised line is set, increase frictional force, facilitates staff to rotate compressing rotating part.
The invention has the beneficial effects as follows: this device is dismountable casing that is arranged on for the Sealing that seals wire outlet hole, in the time occurring that screw thread crumbles, change Sealing, do not need to change casing, save cost.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As Fig. 1, shown in 2, for the detachable wire outlet hole Sealing of combustion gas test terminal, comprise the wire outlet hole 2 that runs through casing 1 sidewall, be arranged on the Sealing 3 in wire outlet hole 2 outsides, described Sealing 3 is cylindric, its center is provided with a perforation 301, and perforation 301 is coaxial with wire outlet hole 2, the diameter of perforation 301 is greater than the diameter of wire outlet hole 2, 301 interior rubber ring 4 and the compressing rotating parts 5 of arranging of boring a hole, compressing rotating part 5 is threaded in perforation 301, compressing rotating part 5 is provided with the coaxial aperture 501 coordinating with wire outlet hole 2, the external diameter of rubber ring 4 is consistent with the diameter of perforation 301, the internal diameter of rubber ring 4 is consistent with the diameter of wire outlet hole 2, on the periphery wall of Sealing 3, be provided with along limit 302, along tapped hole 303 is evenly set on limit 302, Sealing 3 is by being arranged on casing 1 along limit 302.In this device, wire outlet hole 2 is for the turnover of cable, cable and wire outlet hole 2 should be supporting, the diameter of cable equals the diameter of wire outlet hole 2, coaxial aperture 501 is consistent with compressing rotating part 5 axis, when use, cable is through wire outlet hole 2, Sealing 3, rubber ring 4 and compressing rotating part 5, rubber ring 5 is positioned at perforation 301, rotation compressing rotating part 5, rubber ring 4 is oppressed, make rubber ring 4 horizontal expansion of having to, thereby cable is carried out to a circle compressing, ensured sealing, and while needing high leak tightness, rubber ring 4 thickness are increased, and rubber ring 4 oppressive forces are also increased, thereby strengthen sealing, and the very convenient replacing of rubber ring 4 in this device, and this device is in the time that damaging appears in the internal thread of Sealing 3, can take off Sealing 3, again change one, very convenient, and gap between Sealing 3 and casing 1 have rubber ring 4 every the sealing that will not have influence on device.
