In addition, the connecting member that maintains air-tightness by using the elastic force according to the present invention includes a coupling hole 200 formed at one side and the other side of a first conduit 210 (see FIG. 2) A second conduit 300 connected to the first conduit 210 (see FIG. 2) of the bulb 200 so as to be inserted into the bulb 200 and closely contacting the first conduit 210 (see FIG. 2) .

The connecting member may include a coupling member 200, a second conduit 300 and a fixing member 400. The coupling member may be coupled to the valve but may be a first conduit 210 of FIG. 2 formed in the coupling member 200, And the coupling pipe 220 of FIG. 2 may be symmetrically arranged so as to face each other in opposite directions, and may be connected to the second conduit 300 formed on one side and the other side, respectively.

That is, the connecting member may be used to connect two pipelines to each other without using it in connection with the valve.

The expansion pipe 310 is connected to the expansion pipe 310, And an inclined pipe 320 formed to connect the flow pipe 330 and the inclined pipe 320.

The second pipe 300 is composed of an enlarged pipe 310, an inclined pipe 320 and a flow pipe 330 so as to be connected to the first pipe 210, The enlarged pipe 310 and the first pipe 210 can be closely contacted to each other when the first pipe 210 is inserted into the enlarged pipe 310 because the pipe 210 is formed to correspond to the outer diameter of the pipe 210.

When the first conduit 210 is inserted into the expansion pipe 310, the end of the first conduit 210 is closely contacted with the slant pipe 320 of the second conduit 300 to be pressed inside, and the first conduit 210 And the diameter of the flow pipe 330 are equal to each other, the fluid flowing through the second pipe 300 can be introduced into the first pipe 210 without generating vortices due to collision.

A plurality of protruding rings 211 protruding outward are formed on the outer circumferential surface of the first conduit 210 so that when the first conduit 210 is inserted into the enlargement tube 310, Since the inside of the enlarged pipe 310 is pressurized by the second pipe 211, the minute clearance generated by the outer diameter of the first pipe 210 and the inner diameter of the enlarged pipe 310 is blocked to prevent the fluid from flowing out.

At this time, it is preferable that the second conduit 300 is made of a material that has an elastic force and is not corroded, damaged or deformed by chemical characteristics of a fluid flowing therein. For example, the material of the second conduit 300 is excellent in chemical resistance, , And PFA (Perfluoroalkoxy) having good corrosion resistance and excellent standard illuminance and having little adherence of impurities can be used.

 That is, since the material of the second channel 300 has an elastic force, the enlarged pipe 310 having an inner diameter corresponding to the outer diameter of the first pipe 210 is inserted into the protruding ring 211 when the first pipe 210 is inserted, So that it can be inserted into the protruding ring 211 and the protruding ring 211 and the first conduit 210 are closely contacted with each other by elastic force to maintain airtightness.

The second conduit 300 has an inner diameter corresponding to the outer diameter of the second conduit 300 and is located at an outer diameter of the second conduit 300 into which the first conduit 210 is inserted and is connected to the second conduit 300 (Not shown) is separated from the first conduit 210.

The stepped portion formed by the inner diameter of the fixture 400 formed to correspond to the outer diameter of the enlarged pipe 310 and the flow pipe 330 is formed in such a manner that when the fixture 400 is coupled to the coupling hole 200, The inclined pipe 320 is pressed to fix the second conduit 300 in the direction of the housing 100 so as not to be pulled out by the internal fluid pressure.

FIG. 3 is a cross-sectional view illustrating a connection member for maintaining airtightness by using an elastic force according to the present invention and the inside of a channel of a valve including the connection member.

As shown in FIG. 3, the coupling member 200 for maintaining the airtightness using the elastic force according to the present invention and the valve coupling member 200 including the connection member are formed to be larger than the outer diameter of the second conduit 300, And a circular insertion groove 221 is formed to allow the insertion hole 300 to be inserted and fixed.

The coupling pipe 220 formed in the coupling hole 200 is formed on the outer circumferential surface of one side of the first conduit 210 and has an outer diameter larger than that of the first conduit 210. The fixing pipe 400 A first screw thread 223 is formed.

One side of the coupling pipe 220 is connected to the housing 100 and the other side of the coupling pipe 220 is formed with an insertion groove 221 which is inserted inward toward one side so that the first pipe 210 is inserted into the enlarging pipe 310 The enlarged pipe 310 closely attached to the outer circumferential surface of the first conduit 210 is inserted.

The insertion groove 221 is formed in a circular shape and is formed to have a size corresponding to the thickness of the enlarging tube 310 or smaller than the thickness of the enlarging tube 310. When the enlarging tube 310 is inserted into the insertion groove 221, The enlarged pipe 310 can be firmly fitted to the enlarged pipe 221.

In addition, an attachment groove (222) formed by chamfering is formed on the other side of the coupling hole (200) in which the insertion hole (221) is formed, so as to be inclined toward the insertion hole (221).

The tight fitting groove 222 is formed in the enlarged pipe 310 of the second conduit 300 in such a manner that the enlarged pipe 310 pressed by the protruding ring 211 is inserted into the insertion groove 221 in the direction of the insertion groove 221 So that it can be guided to be drawn in.

The fixture 400 includes a coupling hole 410 formed at one end thereof and having an inner diameter corresponding to the outer diameter of the coupling pipe 220 of the coupling hole 200, And a transfer hole 430 formed inside the other end and having an inner diameter corresponding to the outer diameter of the flow pipe 330 of the second conduit 300. The pressurizing hole 420 has an inner diameter corresponding to the outer diameter of the flow pipe 310, .

A second thread 411 is formed on the inner circumferential surface of the coupling hole 410 formed in one end of the fixing member 400 and is coupled with a first screw thread 223 formed on the outer circumferential surface of the coupling pipe 220 of the coupling hole 200 So that the fixing member 400 can be fixed to the coupling member 200.

The pressing hole 420 formed in the interior of the stopper 400 is formed to correspond to the outer diameter of the enlarging pipe 310 of the second pipe 300 and the inner circumferential surface is formed by the protruding ring 211 of the first pipe 210 The outer peripheral surface of the pressurized expanding pipe 310 is pressed by the pressurizing hole 420 of the fixture 400 so that the expanding pipe 310 and the first pipe 210 are closely contacted to improve the airtightness.

The pressing hole 420 of the fixture 400 may be formed to be smaller than the outer diameter of the expansion pipe 310 of the second conduit 300 to improve the airtightness by increasing the pressing force through interference fit.

A contact ring 421 having the same inner diameter as the press hole 420 is formed on the inner surface of the engagement hole 410 of the fixture 400. The contact ring 421 is formed in a contact groove 222 of the first embodiment.

When the fastener 400 is coupled to the fitting 200, the fastening ring 421 is brought into close contact with the fastening groove 222, so that the end of the enlarging tube 310 of the second tube 300 inserted into the insertion groove 221 So that it can not be heard by the protruding ring 211 of the first conduit 210.

When the enlarged pipe 310 of the second conduit 300 is inserted into the first conduit 210, it is pressed by the protruding ring 211 formed on the outer circumferential surface of the first conduit 210, It is possible to prevent the gap from being generated by being spaced apart from the outer circumferential surface of the first conduit 210.

The fixture 400 is fixedly coupled to the coupling hole 200 by a screw and presses the second conduit 300 toward the housing 100.

The transfer hole 430 formed in the fixture 400 is formed to be movable along the outer circumferential surface of the flow pipe 330 of the second conduit 300. When the transfer hole 430 is closely contacted with the slant pipe 320 of the second conduit 300, The fixture 400 is caught by the inclined pipe 320 of the second pipe 300 due to the difference in the diameters of the pressure hole 420 and the feed hole 430 of the first pipe 400.

At this time, due to the difference in diameter between the pressurizing hole 420 and the feed hole 430, the fixture 400 presses the slant pipe 320 of the second pipe 300 toward the housing 100 of FIG. 1 So that it is possible to prevent the second conduit 300 from moving in the direction opposite to the housing 100 of FIG. 1 when the fastener 400 is coupled to the coupling hole 200.

The step generated due to the diameter difference between the pressurizing hole 420 and the feed hole 430 of the fixture 400 has a size corresponding to the outer diameter of the inclined pipe 320 of the second pipe 300, A pressing ring 431 having a shape corresponding to the outer peripheral surface of the pressing ring 431 can be formed.

Since the pressure ring 431 formed on the fixture 400 is in close contact with the outer circumferential surface of the inclined tube 320 of the second conduit 300, the area of the pressurizing ring 431 becomes larger when the second conduit 300 contacts the second conduit 300, So that it can be pressed in the direction of the housing 100.

FIG. 4 is a cross-sectional view illustrating a connection member for maintaining airtightness using an elastic force according to an embodiment of the present invention, and an inner portion of a valve including the connection member, in which a channel is coupled.

The adjusting device 110 is connected to the switch 111 formed in the housing 100 and is configured to lift or lower the switch 111 by rotation. The switch 111 is connected to the opening / 112 so that the fluid flowing from one side of the housing 100 to the other side can be blocked and the fluid can flow to the other side by rotating the regulating device 110 to lift the switch 111.

A coupling hole 200 is formed on one side and the other side of the housing 100 so that a second conduit 300 through which the fluid flows can be coupled and a fastener 400 is formed on the outer circumferential surface of the coupling hole 200, (300) is pressed and fixed in the direction of the housing (100).

When the first conduit 210 formed in the connection pipe is inserted into the second conduit 300, the protruding ring 211 formed on the outer circumferential surface of the first conduit 210 causes the enlargement pipe 310 of the second conduit 300, So that the end is inserted into the insertion groove 221 of FIG. 3 formed in the coupling pipe 220 of the coupling pipe.

When the fastener 400 is threadedly coupled to the coupling pipe 220 of the coupling hole 200, the fastening ring 421 of the fastener 400 is closely fitted to the coupling groove 222 of FIG. 3 formed in the coupling pipe 220 So that the end of the expansion pipe 310 can be pressed so as not to float by the protruding ring 211 of the first pipe 210.

Since the end of the first conduit 210 is formed to be in close contact with the slanting tube 320 of the second conduit 300, the pressurizing ring 431 of the fixing hole 400 is formed in the housing (not shown) 100 direction, the second conduit 300 can be prevented from being separated from the first conduit 210, and the fluid can be prevented from leaking through the gap between the end of the first conduit 210 and the ramp.

The fixture 400 presses the outer circumferential surface of the enlargement tube 310 of the second conduit 300 inwardly pressed by the protruding ring 211 of the first conduit 210 so that the enlargement tube 310 is pressed against the protruding ring 211 So that the fluid can be prevented from coming out, and the airtightness can be improved by forming a plurality of the protruding rings 211.

The enlarged pipe 310 of the second conduit 300 in which the first conduit 210 of the coupling port 200 is inserted is rotated by the protruding ring 211 even if the fastener 400 is rotated by the vibration of the machine So that airtightness can be maintained.

As described above, according to the connecting member and the valve including the connecting member, which maintain the air-tightness by using the elastic force according to the present invention, the gap is not generated without the nut and the airtightness can be maintained, and the separate pressing member such as the sleeve So that the structure is simple and the piping connection can be made easy, and even if the nut is loosened by the vibration of the machine, the airtightness is maintained and the fluid flowing in the piping does not leak to the outside.
