Embodiment
Consult Fig. 1 and Fig. 2, show the leak stoppage device 1 that constitutes according to the utility model one preferred embodiment, and show that this leak stoppage device 1 is installed on the outside of the flange 21,22 of pipeline 2.This leak stoppage device 1 comprises first clamp ring 3, second clamp ring 4 and number valve body 5; Wherein, this two clamp ring 3,4 is the structure of commonly using of several 295714 " leak stoppage devices " of above-mentioned TW certificate number, each clamp ring is made of the semi-circular ring that section roughly is side opening flute profile (ㄈ), and interface 23 outsides of ground clamping at this two flange 21,22 that can be mutually locked; And protuberance 31,41 and recess 32,42 are set at the two ends of each clamp ring 3,4 respectively, and in this outside, two ends beam barrel 33,43 usefulness that can align are set respectively and lock for screw 6 passes in order to chimeric and form a ring body mutually.
The chamber 34,44 that can provide leak-stopping agent 7 to inject is provided in the inside of each clamp ring 3,4, and has at least one leak-stopping agent inlet 35,45 in the outside, in the present embodiment, the outside that ties up to each clamp ring 3,4 is provided with three separated inlets 35,45, and each inlet can be installed for a valve body 5.
The utility model is characterised in that the design of this valve body 5; Cooperate Fig. 3 and shown in Figure 4, this valve body 5 to comprise a valve seat 51, be assembled in a valve rod 52 and at least one bushing pipe 54 in this valve seat 51 rotationally; This valve seat 51 is preferably formed by casting, it has a cross through hole 512 and and is the vertical joining hole 513 that intersects with this cross through hole, in this through hole 512 and this joining hole 513, screw thread 511,514 can be set respectively, and connect a joint 53 at an end of this cross through hole 512, first end 531 of this joint 53 and second end, 532 outer surfaces are respectively equipped with screw thread, make the two ends of this joint 53 can lock individually in cross through hole 512 1 ends of a pair of inlet of answering 35,45 and this valve body 5, and each valve seat 51 is connected the inlet outside.
The lower end 521 that this valve rod 52 has in the joining hole 513 that stretches into valve seat 51 reaches the upper end 522 of giving prominence to outside the valve seat 51; In the present embodiment, at this joining hole 513 internal locks unification pole socket 55, this pole socket 55 has a center hole 551 usefulness and passes for the upper end 522 of this valve rod 52, makes when this valve rod 52 is assembled in this joining hole 513, can utilize this pole socket 55 to be locked on this joining hole 513 and form the location; Be provided with a perforation 523 again in the lower end 521 of this valve rod 52, when rotating this valve rod 52, this perforation 523 can form with this cross through hole 512 and be communicated with or be not communicated with.
This bushing pipe 54 is that an outside dimensions can closely be inserted in the body in this cross through hole 512, and its inside has a pore 541; Best, this bushing pipe 54 is made by the little metal of expansion coefficient, and for example brass material makes this bushing pipe 54 be difficult for producing big expanding with heat and contract with cold in the environment of temperature variation.
The bushing pipe 54 that is inserted in this cross through hole 512 passes this joining hole 513, makes that its lower end 521 can be inserted in this bushing pipe 54 across when this valve rod 52 inserted in this joining hole 513; In the present embodiment, because the external diameter of this valve rod 52 is greater than this bushing pipe 54, so, in the time of in this valve rod 52 inserts this bushing pipe 54 across, be that this bushing pipe 54 is blocked into two sections (as shown in Figure 4); Perhaps, if the external diameter of this valve rod 52 is during less than this bushing pipe 54, a hole (not shown) can be set on this bushing pipe 54 in advance provides this valve rod 52 to insert combinations.
After the lower end 521 of this valve rod 52 was inserted in this bushing pipe 54, the perforation 523 of this valve rod 52 can be adjusted to the pore 541 of this bushing pipe and is communicated with or is not communicated with; As shown in Figure 4, when the perforation 523 of this valve rod 52 was communicated with the pore 541 of this bushing pipe, the through hole 512 of this valve seat 51 formed open, and as shown in Figure 5, when this perforation 523 was not communicated with this pore 541, the through hole 512 of this valve seat 51 forms closed.
The leak stoppage device 1 that constitutes according to the utility model is carrying out need not dismantling flange in the leak-stopping operation.Promptly when fluid seepages take place or leak in the interface 23 of the flange 21,22 of connecting pipeline 2, cooperate Fig. 2 and shown in Figure 4, by this first clamp ring 3 and second clamp ring 4 interface 23 outsides of ground clamping that are mutually locked at this two flange 21,22, afterwards, cross through hole 512 outer ends with the wherein arbitrary valve seat 51 of colloid-injecting gun 8 insertions, and for example the leak-stopping agent 7 of foaming body is injected in the chamber 34,44 of first clamp ring 3 and second clamp ring 4, then, from each valve seat 51 perfusion leak-stopping agent 7, leak-stopping agent 7 is full of in the chamber equably in order.After the perfusion operation is finished, rotate the through hole 512 (as shown in Figure 5) of upper end 522 to close valve seat 51 of each valve rod 52, then, the leak-stopping agent 7 in chamber 34,44 solidify to form sealing layer, just reaches the effect of filling up gap leakage and fast leak-stopping.
Simultaneously, leak stoppage device 1 according to the utility model formation, by this brazen bushing pipe 54 being housed in these valve seat 51 internal sleeve, make through hole 512 pipelines of this valve seat 51 can not cause distortion because of long-term expanding with heat and contract with cold, and then make this valve rod 52 and these valve seat 51 internal pipelines can not take place to block mutually so that can't rotation valve rod or form breach so that cause leakage problems, in addition, also form good docking (as shown in Figure 4) between these bushing pipe 54 end faces and joint 53 second ends 532.
Aforementioned is the explanation of the utility model structure being done preferred embodiment, is can do multiple variation or modify embodiment and comply with design spirit of the present utility model, and for example, this bushing pipe 54 is not restricted to brass material and makes, and the material that other expansion coefficient is little is also passable.Be with, for being familiar with obvious replacement and the modification that this skill personage can do, will be incorporated within the claim that the utility model advocates.
