Abstract
The utility model relates to a pipeline sealing blocking device which is suitable for being used when the end of a pipeline is sealed and blocked or the pipeline is sealed and blocked casually fir pressure test. The pipeline sealing blocking device is characterized in that is a centre hole in which a screw rod is penetrated is arranged on a plugging plate; the left front part of the screw rod is connected with a supporting mechanism, and the right rear part of the screw rod is provided with a stress keyboard; a compression spring is sheathed on the screw rod between the plugging plate and the supporting mechanism. When the pipeline sealing blocking device is used, the left front part of the screw rod and the supporting mechanism are arranged in a pipe mouth, and after the screw rod is rotated, the plugging plate and the pipe mouth can be tightly sealed. The pipeline sealing blocking device has the advantages of convenient installation and use, labor saving, time saving and material saving.
Description
The utility model relates to the pipe plugging technical field, uses when being applicable to pipe end shutoff or interim shutoff bulge test.
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 user.
The purpose of this utility model provides a kind of simple in structure, easy to use, and both can be used as the pipe plugging plate and used, but the pipeline plug that uses during bulge test again.
The utility model is achieved in that and is provided with a center hole on the shutoff plate, place a screw mandrel in this center hole, the left front portion of screw mandrel is connected with supporting mechanism, and the right back portion of screw mandrel is provided with stressed keyboard, is set with pressure spring on the screw mandrel between shutoff plate and the supporting mechanism; Supporting mechanism is by preceding joiner, back joiner, front support rod, back stay, leg, pin are formed, preceding joiner is provided with the center interior threaded hole, and cooperating connection with wire rod thread, back joiner is provided with the center unthreaded hole, is placed in the screw mandrel middle part, can slide along screw mandrel, preceding joiner connects with front support rod respectively, and back joiner connects with back stay respectively, and forward and backward corresponding pole connects with same leg altogether; According to the size of caliber, leg can be provided with 3-8, and is distributed on the circumference.Be shutoff tube head effectively, be provided with seal washer on the shutoff plate, shutoff plate central hole is provided with the female overcoat in town, and this presses down female overcoat, and to be furnished with the town female, and this presses down in female overcoat and is provided with seal ring.
That compared with the prior art the utility model has is easy to install, the saving of labor, save time, save advantages such as material.
Below in conjunction with accompanying drawing the utility model is explained
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 for the utility model and the mouth of pipe
Referring to accompanying drawing: have a center hole 12 on the shutoff plate, place a screw mandrel 17 in this center hole 12, the left front portion of screw mandrel 17 is connected with supporting mechanism, and the right back portion of screw mandrel 17 is provided with stressed keyboard 9, and this keyboard 9 is an one with screw mandrel 17.On the screw mandrel between shutoff plate 6 and the supporting mechanism, be set with pressure spring 4 (see figure 1)s; Supporting mechanism is made up of preceding joiner 18, back joiner 13, front support rod 1, back stay 3, leg 2, pin 15, preceding joiner 18 is provided with center interior threaded hole 16, and cooperate connection with wire rod thread, back joiner 13 is provided with center unthreaded hole 14, and is placed in screw mandrel 17 middle parts, can slide along screw mandrel, preceding joiner 18 connects with front support rod 1 respectively, back joiner 13 connects with back stay 3 respectively, and forward and backward corresponding pole connects with same leg, and 3 leg (see figure 2)s can be set on circumference; For the shutoff ferrule is good, rubber gasket 5 is set on shutoff plate 6, shutoff plate central hole is welded with the female overcoat 8 in town, in the female overcoat 8 in town asbestos rope seal ring 11 is set, and this presses down female overcoat and is furnished with female 10 (see figure 2)s in locking town.
During actual the use, supporting mechanism is put into the mouth of pipe, rotary screw 17 then, because screw mandrel is stopped by its right part keyboard 9, make screw mandrel produce pulling force to preceding joiner 18, compress by front support rod, leg line up inwall, back joiner 13 pressure springs 4 make the mouth of pipe compress rubber seal simultaneously, to form mouth of pipe place's high pressure sealing, pressure gauge 20 on the shutoff plate can show the pressure size of suppressing, on the shutoff plate, have and take over mouthfuls 7, be used to install gas, water lines, suppress and finish, unscrew screw mandrel, can take off the shutoff (see figure 3).
