Abstract
The utility model relates to a low pressure sealing and connecting device of a fluid pipeline, in particular to an insert-type pipeline connecting assembly. The insert-type pipeline connecting assembly squeezes an elastic sealing ring by fastening two flanges, and therefore a pipe can be closely contacted with the elastic sealing ring, and the purpose that pipelines with different pipe diameters can be in low pressure and sealing connection is achieved. The insert-type pipeline connecting assembly is simple in structure, convenient to operate, wide in application range, low in cost and beneficial for popularization. The purpose of dismounting a pipe fitting can be achieved through one person and two spanners, and the processes of assembling and dismounting can be benefited in narrow and small space. The mounting distance and the installation angle can be adjusted effectively.
Description
Technical field
The utility model relates to the low pressure seal connection set of fluid circuit, is specially a kind of plug-in type pipeline connection part.
Background technique
Conventional fluid pipe fitting is tightly connected can not adjustable range and angle, often can not accurately locate because above-mentioned uncertain factor causes, and causes on-the-spot rectification; And after two pipe fittings connect, usually because the whole Transporting length issue needs separately transportation of dismounting, present Connecting format more complicated, dismounting is wasted time and energy repeatedly.
The model utility content
The purpose of this utility model is exactly the defective that exists for prior art, provide a kind of simple in structure, dismounting fast, it can imitate the plug-in type pipeline connection part of regulating mounting distance and setting angle.
Working principle of the present utility model is: make its extruding elastic seal ring by fastening two flanges, thereby make pipe and seal ring close contact, realize that the low pressure seal of pipeline different tube diameters connects.Its concrete technological scheme is: comprise assembly: loose flange, fastening flange and seal ring, wherein fastening flange and loose flange can be fastening mutually, and the fastening flange inboard is provided with the groove that seal ring is installed.During use, the Large Diameter Pipeline pipe is connected with fastening flange, then penetrate in the pipe with small pipe diameter pipe according to seal ring and the loose flange of caliber with suitable model, then pipe with small pipe diameter Guan Yiduan is inserted in the Large Diameter Pipeline pipe by fastening flange, then two flanges are relatively fastening, make seal ring in place in groove, and further compresses seal make itself and pipe with small pipe diameter pipe outer wall close contact, thus being tightly connected of realization pipeline.
The outside of described fastening flange is provided with inner bore chamfering, can reduce flow rate effect in the pipeline.
Described loose flange is provided with inner bore chamfering, can make the pipe quick insertion.
Described fastening flange and movable fastening by the screw bolt and nut connection.
Advantage of the present utility model: simple in structure, easy to operate, single two spanners can be realized the dismounting of pipe fitting, more are beneficial to assembly and disassembly at small space; Can effectively regulate mounting distance and setting angle, applied widely; Cost is lower, is beneficial to popularization.
Description of drawings
Fig. 1 is the structural representation after embodiment 1 connects;
Structural representation when Fig. 2 is embodiment's 1 use state;
Structural representation when Fig. 3 is embodiment's 2 use state;
Wherein: 1, loose flange, 2, seal ring, 3, fastening flange, 4, (4.1,4.2) inner bore chamfering, 5, bolt, 6, nut, 7, the pipe with small pipe diameter pipe, 8, the Large Diameter Pipeline pipe, 9, the location otic placode.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1-2, a kind of plug-in type pipeline connection part is modular construction, comprise assembly: loose flange 1, fastening flange 3 and seal ring 2, fastening flange 3 inboards are provided with groove, the outside that seal ring 2 is installed and are provided with inner bore chamfering 4.2, and loose flange 1 is provided with inner bore chamfering 4.2.During use, with Large Diameter Pipeline pipe 8 and fastening flange 3 welding, then seal ring 2 and loose flange 1 are penetrated in the pipe with small pipe diameter pipe 7, then pipe with small pipe diameter pipe 7 one ends are inserted in the Large Diameter Pipeline pipe 8 by fastening flange 3, then two flanges are relative fastening with nut 6 with bolt 5, make seal ring 2 in place in groove, and further compresses seal 2 make itself and pipe with small pipe diameter pipe 7 outer wall close contacts, thus being tightly connected of realization pipeline.During dismounting each bolt is unclamped the part screw thread, can extract pipe with small pipe diameter pipe 7.
Because the elastic packing of seal ring, this assembly can regulate ± and 4 ° pipe angle of inclination, carry out the declinate degree and install, see Fig. 2.
On the basis of embodiment's 1 structure, be connected respectively location otic placode 9 at pipe with small pipe diameter pipe 7 and Large Diameter Pipeline pipe 8 respectively, then connect with the location otic placode 9 of screw bolt and nut with correspondence, thereby prevent that assembly is movable.
The utility model is simple in structure, and is easy to operate, both reduced the pipe fitting delivery unit, avoided again field erected repeatedly dismounting.Single two spanners can be realized the dismounting of pipe fitting, more are beneficial to assembly and disassembly at small space, and can effectively regulate mounting distance and setting angle, and are applied widely; Cost is lower, is beneficial to popularization.
For those skilled in the art, under the prerequisite that does not break away from the utility model principle, might make some improvements and modifications to concrete size and number of bolts, these improvements and modifications also should be considered as protection domain of the present utility model.
