Embodiment
Below in conjunction with Figure of description the embodiment of the utility model is done further detailed explanation.
As shown in Figure 1, the utility model comprises screw rod 1, fastening nut 6; Rubber pad 7; Sealing steel plate 8 and fixing device, wherein rubber pad 7 is arranged on the back side of sealing steel plate 8, and screw rod 1 passes the through hole that is arranged on sealing steel plate 8 and the rubber pad 7; Fastening nut 6 is rotated on the screw rod 1 of sealing steel plate 8 positive sides, and fixing device is arranged on the screw rod 1 of sealing steel plate 8 back sides one side.
Said fixing device comprises nut 2; Rubber bumper 4; Bearing 5 and at least two travel(l)ing rests, nut 2 are rotated on the screw rod 1 of sealing steel plate 8 back sides one side, and bearing 5 is fixed on screw rod 1 end of sealing steel plate 8 back sides one side; Travel(l)ing rest adopts movable connection method to be connected with nut 2, bearing 5 respectively, and rubber bumper 4 adopts movable connection method to be connected an end of travel(l)ing rest.
Said travel(l)ing rest comprises main support rod 3a and auxilliary strut 3b, and the end of auxilliary strut 3b adopts movable connection method to be connected with the body of rod of main support rod 3a.
The diameter of the diameter of said through hole and screw rod 1 adapts.
Said movable connection method is the mode of being articulated and connected.
Said main support rod 3a and auxilliary strut 3b adopt square tube, can guarantee the strength and stiffness of orifice sealing device.
Fixing device in the utility model adopts at least two travel(l)ing rests, can play more firm effect for the fixing of orifice sealing device and pipe 9 like this.
As shown in Figure 2, in the practical implementation process, rotary screw 1; Because bearing 5 is relatively-stationary with screw rod 1, therefore, nut 2 will advance or retreats along screw rod 1 in the rotary course; Regulate the folding size of travel(l)ing rest, the inwall of orifice sealing device and pipe 9 is adjacent to, because the frictional force of rubber bumper 4; Realize the fixing of orifice sealing device and pipe 9; Rotate fastening nut 6 roof pressures sealing steel plate 8 this moment, the rubber pad 7 at the sealing steel plate 8 and the back side thereof and pipe 9 are clamped, accomplish the sealing of line up.
The operation interval of orifice sealing device depends on main support rod 3a and auxilliary strut 3b size and angle to each other in the travel(l)ing rest, pipe 9 diameter that orifice sealing device can seal, and minimum is: when main support rod 3a becomes 180 ° of angles with auxilliary strut 3b; Be to the maximum: main support rod 3a and screw rod 1 are at an angle of 90 the time; As long as in this interval, this device all can be realized the sealing of line up, but needs to explain the pipe when not using this device sealing travel(l)ing rest limit position; During limit position; Rubber bumper 4 is stressed hardly, and therefore under this kind state, orifice sealing device does not have the effect of sealing.
As stated, the utility model is through adjusting screw rod 1, and realization seals the pipe 9 of different-diameter and uses same set of device, makes simply, and convenient and reliable operation can not come off.The sealing of mouth of pipe when this device is used for air tightness test, special in not flanged (FLGD) ferrule, make simply, easy to operate, but repetitive cycling is used.When carrying out the segmentation air tightness test, because the pipe of opening maybe be many, can adopt different segmented seal form mix and match to use, it is generally just enough to be equipped with 3-5 orifice sealing devices when therefore constructing.
Combine accompanying drawing that the mode of execution of the utility model has been done detailed description above; But the utility model is not limited to above-mentioned mode of execution; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.
