Description

A kind of seal plug for detection
Technical field
This utility model relates to a kind of seal plug for detection.
Background technology
Along with the development of plastic conduit industry, small-bore thin-walled plastic flexible pipe obtains in combustion gas and feedwater distributing system To being widely applied.During installing, conventional device for detecting sealability is inapplicable for this type tubing sealing The detection of energy.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of seal plug for detection.
This utility model solves its technical problem and be the technical scheme is that
A kind of seal plug for detection, including front plug and rear plug, described front plug and rear plug all include One main body and gland, main body is provided with a screwed hole, and described gland one end is provided with the screw rod coordinated with screwed hole, the other end It is provided with end plate, described screw rod is arranged with a sealing ring.
Be provided with in the gland of described front plug one for ventilation through hole, the screw rod of this gland extends screwed hole, should Screw rod extends the end of screwed hole and is connected with a three-way valve, two other interface of three-way valve respectively with a Pressure gauge and supply Device connects.
The beneficial effects of the utility model are: use this utility model of said structure by gland and sealing ring being put into In small caliber flexible pipe, it is rotated further by main body, by the end face of main body one end and the end plate of gland, sealing ring is extruded so that The inwall being adjacent to small caliber flexible pipe expanded outward by sealing ring, is formed and seals, can carry out stress test.This utility model structure Simply, convenient to operation.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is the schematic diagram of front plug;
Fig. 2 is the schematic diagram of rear plug.
Detailed description of the invention
With reference to Fig. 1~Fig. 2, this utility model is a kind of seal plug for detection, including front plug 1 and rear plug 2, Front plug 1 and rear plug 2 all include a main body 3 and gland 4, and main body 3 is provided with a screwed hole, and gland 4 one end is provided with The screw rod 5 coordinated with screwed hole, the other end is provided with end plate 6, and screw rod 5 is arranged with a sealing ring 7;As it is shown in figure 1, front plug Be provided with in the gland 4 of 1 one for ventilation through hole 8, the screw rod 5 of this gland 4 extends screwed hole, and this screw rod 5 extends spiral shell The end of pit is connected with a three-way valve 9, and two other interface of three-way valve 9 is connected with a Pressure gauge and feeder respectively. Use this utility model of said structure by gland 4 and sealing ring 7 are put into small caliber flexible pipe, be rotated further by main body 3, logical Sealing ring 7 is extruded by the end plate 6 of the end face and gland 4 of crossing main body 3 one end so that sealing ring 7 is expanded outward and is adjacent to osculum The inwall of footpath flexible pipe, is formed and seals, and can carry out stress test by Pressure gauge at three-way valve.The letter of this utility model structure Single, convenient to operation.
Above-described embodiment is preferred version of the present utility model, and this utility model also can have other embodiments.Ability The technical staff in territory also can make equivalent variations or replacement on the premise of this utility model spirit, the change of these equivalents Type or replacement are all contained in the scope set by the application claim.
