Abstract

The invention relates to a leaking stoppage device for a tubular heat exchanger heat exchange tube. The leaking stoppage device comprises an expanding and tightening body which is of a circular-platform-shaped structure with the large front end and the small rear end, a sealing body closely attached to the outer side face of the expanding and tightening body, a threaded connecting rod, a pre-tightening body, a pre-tightening force keeping body and a pressure distributing body. The sealing body can be placed in the heat exchange tube and closely attached to the inner wall of the heat exchange tube. The front end of the expanding and tightening body extends forwards by a part compared with the front end of the sealing body. The expanding and tightening body and the sealing body can relatively move. The pre-tightening force keeping body is arranged between the pre-tightening body and the pressure distributing body. Chamfers are arranged on the periphery of the front end of the sealing body. The expanding and tightening body is of a solid structure or a structure with one closed end. In the using process of the leaking stoppage device, welding is avoided, sealing is reliable, and the problem that mass leakage points are caused by leakage of one heat exchange tube is forcefully solved.

(2) seal of leak stoppage device is plastic material, elastic deformation is produced under the effect of pretightning force and tensioner body, itself and heat exchanger tube inwall are fitted tightly, tube side and shell side medium are separated, reach leak stopping and regulate the object of heat exchange area, whole Process of Leaking Stoppage on all the other heat exchanger tubes without any impact.
Accompanying drawing explanation
the structural representation of the leak stoppage device of Fig. 1 a kind of pipe heat exchanger heat exchanger tube of the present invention;
in figure 1, seal; 2, tensioner body; 3, pressure-distributing bodies; 4, pretightning force holder; 5, pretension body; 6, threaded rod.
Detailed description of the invention
for making the object of the embodiment of the present invention and technical scheme clearly, below in conjunction with the accompanying drawing of the embodiment of the present invention, the technical scheme of the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of protection of the invention.
those skilled in the art of the present technique are appreciated that unless otherwise defined, and all terms used herein (comprising technical term and scientific terminology) have the meaning identical with the general understanding of the those of ordinary skill in field belonging to the present invention.Should also be understood that those terms defined in such as general dictionary should be understood to have the meaning consistent with the meaning in the context of prior art, unless and define as here, can not explain by idealized or too formal implication.
the implication of " inside and outside " described in the present invention refers to relative to equipment itself, in the direction of sensing equipment inside is, otherwise is outward, but not the specific restriction to equipment mechanism of the present invention.
the indirect connection that can be the direct connection between parts also can be by other parts between parts of the implication of " connection " described in the present invention.
it is front end that the implication of " front end, the rear end " described in the present invention refers to the part first filled in heat exchanger tube when leak stoppage device of the present invention uses, and the part be exposed at outside heat exchanger tube is rear end.
as shown in Figure 1, the leak stoppage device of pipe heat exchanger heat exchanger tube of the present invention, comprising:
be arranged on the tensioner body 2 of leak stoppage device center, it is the round table-like structure that front end is large and rear end is little;
fit tightly the seal 1 on tensioner body 2 lateral surface, the shape of the lateral wall of seal 1 is consistent with the shape of the madial wall of heat exchanger tube, seal 1 can be put into heat exchanger tube inside and be close to the inwall of heat exchanger tube, the front end of tensioner body 2 extends a part forward compared with the front end of seal 1, can movement mutually between tensioner body 2 and seal 1;
threaded rod 6 and pretension body 5, the front end of threaded rod 6 is fixed on the rear end of tensioner body 2, and the rear end of threaded rod 6 is threaded with between pretension body 5;
pretightning force holder 4 and pressure-distributing bodies 3, pretightning force holder 4 is arranged between pretension body 5 and pressure-distributing bodies 3, for strengthening the pretightning force between each parts of leak stoppage device; Pressure-distributing bodies 3 is arranged between pretightning force holder 4 and seal 1, and it reduces by the contact area increased between the rear end of seal 1 pressure be applied on seal 1 rear end.
for the ease of filling in heat exchanger tube by seal 1, chamfering can be set to by around the forward end of seal 1.
as one embodiment of the present invention, seal 1 adopts plastic material.Due to the characteristic of plastic material, can there is obviously distortion and not be destroyed in it under external force.
as another embodiment of the invention, tensioner body 2, pressure-distributing bodies 3 and pretension body 5 all adopt rigid material.
as a kind of embodiment of the present invention, pretightning force holder 4 adopts elastomeric material.Such as elastic washer goes for the present invention.
for ensureing sealing effectiveness, tensioner body 2 be solid construction or is the closed structure in one end.
under leak stoppage device is used in each chemical environment, according to the difference of environment for use, seal 1, tensioner body 2, pressure-distributing bodies 3, pretightning force holder 4 and pretension body 5 all can adopt exotic material.Or seal 1, tensioner body 2, pressure-distributing bodies 3, pretightning force holder 4 and pretension body 5 all adopt resistant material.
leak stoppage device entirety is filled in and needs in heat exchanger tube to be processed, the lateral wall of seal 1 is close on the madial wall of heat exchanger tube, turn pretension body 5, make pretension body 5 in rotary moving in threaded rod 6, drive tensioner body 2 rearward to move gradually, because the front end size of tensioner body is comparatively large, the madial wall direction of seal 1 to heat exchanger tube extrudes by tensioner body gradually, seal 1 more closely fits together with the inwall of heat exchanger tube, finally reaches seal 1 with sealing between heat exchanger tube to contact.Thus realize by tube side and shell side medium separately, reach leak stopping and regulate the object of heat exchange area, whole Process of Leaking Stoppage on all the other heat exchanger tubes without any impact.
the present invention can address the problem: 1, tubular heat exchanger fast blockage; 2, tubular heat exchanger is when underrun, in order to regulate heat exchange area, reduces energy consumption, improves the quality of products.
these are only embodiments of the present invention, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
