Abstract
The utility model relates to a pipeline instant stopper, which is used for the pressure test of the pipeline. The pipeline instant stopper is characterized in that the stopper plate is provided with a middle hole, the internal part of which is provided with a screw rod; the left front part of the screw rod is connected with a telescoping and adjustable fixing clamping disk for supporting the internal diameter of the supporting tube mouth; the right rear part of the screw rod is provided with a stressed keyboard, and the stopper plate is also provided with a sealing washer, the casing of the locking nut, etc. When the pipeline instant stopper is used, the telescoping and adjustable fixing clamping disk is connected with the stopper plate with the screw rod, and the rotating screw rod can make the stopper plate and the tube mouth sealed. The utility model has the advantages of convenient arrangement and usage, labor saving, time saving, and material saving.
Description
The utility model relates to the pipe plugging technical field, uses when being applicable to the interim shutoff bulge test in pipeline two.
At present, when the piping erection construction is suppressed, all adopt interim blind plate weldering stifled, after the bulge test, blind plate and tube head must be cut off together, cause waste of material, prolong the engineering time, bring many inconvenience to the builder.
The purpose of this utility model provides a kind of simple in structure, easy to use, pipeline instant stopper of being applicable to φ 108mm to φ 1050mm caliber.
The utility model is achieved in that to making the shutoff plate can use the shutoff tube head easy for installation repeatedly, on the shutoff plate, be provided with a mesopore, in this mesopore, be provided with a leading screw, the left front portion of leading screw is connected with flexible adjustable fixedly chuck, the right back portion of screw mandrel is provided with stressed keyboard, described flexible adjustable fixedly chuck, by land, supporting foot lever forms, size according to caliber, support foot lever and can be provided with 3-8, support that foot lever is uniform to be connected on the land, each supports foot lever by back silk pole, silk braid, preceding silk pole, the pole pin connects to form, between back silk pole and the land movable corner is arranged, between preceding silk pole and the pole pin movable corner is arranged, make it form the nature activity, support foot lever and bore are stably supported; Be shutoff tube head effectively, on the shutoff plate, be provided with seal washer, between shutoff plate and the tube head by envelope gasket circle with both tight seals; The place also is provided with the locknut overcoat at shutoff plate mesopore, and this overcoat has connected locknut.
During actual the use, the adjustable fixedly chuck that will stretch earlier is installed in spout diameter, by supporting foot lever, make itself and spout diameter fixed support by rotating silk braid, leading screw is penetrated by shutoff plate mesopore, its front end and land mesopore precession scyewed joint are owing to stopping of stressed keyboard again, make leading screw produce pulling force to land, further precession leading screw, thus make shutoff plate and ferrule, behind stressed keyboard, add asbestos rope, compress locking with locknut again, can be with mouth of pipe tight seal; On the shutoff plate, can have import and export, be used for install taking over, pressure gauge, suppress and finish, unscrew leading screw and can take off shutoff.
Compared with the prior art the utility model has easy to install, saving of labor, saves time, saves advantages such as material.
Below in conjunction with accompanying drawing the utility model is made the following instructions:
Fig. 1 is the utility model structural representation
Fig. 2 is Fig. 1 left side TV structure schematic representation
Fig. 3 installs and uses view with the mouth of pipe
Referring to accompanying drawing: have a mesopore 10 on the shutoff plate 9, be provided with a leading screw 7 in mesopore 10, the left front portion of leading screw is connected with flexible adjustable fixedly chuck, and the right back portion of screw mandrel is provided with stressed keyboard 11; Flexible adjustable fixedly chuck is made up of land 5, support foot lever, and each supports foot lever is to be connected to form by back silk pole 4, silk braid 3, preceding silk pole 2, pole pin 1.(see figure 1), each support foot lever of uniform connection on land 5, it can have 6 series, and promptly setting and supporting foot lever quantity is 3-8, and available 2 to the 6 kinds of pipeline specifications of each series.Fig. 2 is provided with 4 embodiments that support foot lever; On shutoff plate 9, be connected with seal washer 8,, be provided with locknut overcoat 13, and connected locknut 12, add asbestos rope 18, compress locknut 12, can guarantee positive confinement in stressed keyboard 11 backs for making the sealing of shutoff plate mesopore place tight; Change for adapting to different calibers, be connected by drift bolt 6 between back silk pole 4 and the land 5,0 °～15 ° movable corner are arranged, be connected with 0 °～15 ° movable corner by drift bolt 6 between preceding silk pole 2 and the pole pin 1, make it that certain activity be arranged when supporting spout diameter, in order to improve the stability that supports spout diameter.During use, flexible adjustable fixedly chuck and spout diameter 17 support, and rotate silk braid 3 with the adjustment hole on the silk braid 3 16, make supporting ﹠ stablizing, leading screw again with mesopore 15 scyewed joint of land 5, with fastener hole 19, rotational lead screw 7 makes the shutoff plate 9 and the mouth of pipe produce sealing closely; On shutoff plate 9, have and import and export 14, be used for installing and take over and pressure gauge.(see figure 3).
