Embodiment
Fig. 1 illustrates the first embodiment of the present invention.Here, the part of valve chamber illustrates with the form that short tube 1 and the portion within it of being suitable for accept the joint 5 of short tube (pipe stub) 1.Joint 5 is equipped with first helical thread portion 6, and it for example is used for being threaded onto the hot-water cylinder (not shown) by being formed on the tank skin, as described in the Norwegian patent applications No.2004 1923.Described joint 5 comprises the flange 7 that forms surface of contact with respect to tank skin.Relative with screw thread 6, this joint 5 is equipped with second helical thread portion 8.
In addition, the second straight outer matrix section 16 is transformed into second tapering part 21, itself so that be transformed into the diameter three straight outer matrix section 22 bigger than the second straight outer matrix section 16.The 3rd outer matrix section 22 is equipped with the circular groove 24 that is used for locking ring 25.This locking ring is made of the clasp of opening, so that diameter can enlarge.Vestibule 23 runs through short tube 1.Described short tube 1 further combines with the valve chamber that can be any kind, known to itself, will be connected with jar.
In inside, nut 27 has the first portion 29 in the face of flange 7, and described part has the diameter bigger than the nut portion 28 that is shaped on screw thread.On the opposite side of helical thread portion 28, nut also has the diameter part 30 bigger than helical thread portion 28.In the end of away from flange 7, nut 27 has flange 31 inwardly.At the sidepiece of the flange 31 of facing part 30, this flange has the recess 32 in abutting connection with convex shoulder 33.
Referring now to being connected of Fig. 2-6 explanation short tube 1 and joint 5.When being opened, nut 27 is positioned on second helical thread portion 8 of joint 5.Be placed with locking ring 25 at joint 5 with between inward flange 31.This locking ring 25 is placed on the top of the end face of joint 5 loosely.
When the valve chamber that has short tube 1 is imported in the joint, will enter with the first straight part 14 of minimum diameter.This part plays the effect that enters the surface and makes short tube 1 with respect to joint 5 centerings.The second straight part 16 is passed locking ring 25, and this locking ring 25 has the big internal diameter of external diameter than O shape ring 19,20.Thus, second tapering part 21 contacts with locking ring 25.Described tapering part 21 will be expanded locking ring 25 and force it to enter the hollow space that the part 30 by nut forms, and like this, the 3rd straight part 22 just can be directed in the locking ring 25.Almost at the same time, short tube 1 enters first of joint 5 with the first straight part 14 and heads straight in the bore portion 10.Thus, short tube 1 centering in joint 5.Punctual when 25 pairs of groove 23 and locking rings, this locking ring 25 just snaps in this groove.Can hear click clearly, thereby setter is known, valve has been installed correctly. O shape ring 19,20 heads straight for bore portion 11 near second in the joint 5 and forms sealing then.
When jar is pressurized, pressure will guarantee that valve chamber has lifting slightly with respect to joint 5, as shown in Figure 6.Locking ring 25 will be compressed between the wall and nut flange 31 of groove 24 then.Fig. 7 shows this details.Locking ring is herein in the wall 24a that is compressed in groove 24 with form between the downside of flange 31 of recess 32.When the diameter that recess 32 has was suitable for locking ring 25 and is in the groove 24, promptly locking ring did not have the diameter of locking ring 25 when stressed, and therefore, the locking ring that is in position shown in Fig. 6 and 7 can not radially outwards move.Like this, make with regard to having guaranteed locking ring to engage with groove 24 securely and be connected the moving possibility that do not fluff.
If short tube 1 is separated with joint 5, then must unscrew nut 27.Preferably hand-tight make-up and also can unscrew or rely on the light power of instrument to unscrew with hand is thus for example used Pipe wrench.Nut 27 is backed out from second helical thread portion 8.Thereby, the valve chamber that has short tube 1 can be extracted from joint 5.Locking ring 25 will be in the groove 24, but locking ring 25 must be routed up from groove 24 before valve is installed once more.This back nut 27 and locking ring 25 are installed on the joint, and as shown in Figure 2, short tube just can guide and joint 5 clampings once more like this.
Fig. 8 illustrates the second embodiment of the present invention.This embodiment's principle is same as the previously described embodiments.Therefore, will only illustrate that difference, those of ordinary skill in the art will be appreciated that, this second embodiment has the feature identical with first embodiment in all respects.Here, the joint 5 that is fixed on the jar is equipped with short tube 1.Short tube 1 comprises the groove 24 that is used for locking ring 25.Valve chamber is equipped with clamp holder 34, and its outside has helical thread portion 35, and inside has the groove 17 that is used for O shape ring 19.Nut 27 is screwed on the helical thread portion 35, and locking ring 25 is placed between the flange 31 of the end of clamp holder 34 and nut 27.Short tube 1 is imported into thereafter in the clamp holder, snaps in until locking ring 25 till the appropriate location of groove 24.
Though should be understood that an O shape ring only is shown in Fig. 8, also can use two O shape rings.Two O shape rings will provide better leakproof Security.Because the increase and the reduction of pressure, when valve chamber in joint 5 forward and when mobile backward, some fluids can see through an O shape and encircle.Another O shape ring will guarantee that this fluid can not leak fully.
In Fig. 8, can see, not be shaped on hollow space in flange 31 inside of nut 27.This may give lower margin of safety to unconsciously dismantling valve chamber, but in most of the cases will bring into play gratifying effect.Yet the hollow space on the nut flange will mean that described connection is connected same safety with the tradition of using now at least.
Shown in Fig. 9-13 the of the present invention the 3rd and be presently preferred embodiment.Herein, the part of valve chamber also is illustrated, the joint 5 that it has short tube 1 and is suitable for accepting in inside short tube 1.Described joint 5 is made relevant described joint with Fig. 1 substantially.Yet this joint has a straight end 40, rather than tapering part 13, and this straight end 40 has the small circular top 46 with respect to valve chamber.
The short tube 1 of this valve chamber is made into slightly different according to the embodiment shown in Fig. 1.At its end, it has the first straight outer matrix section 14 that extends to tapering part 41.The second straight part 16 is followed thereafter.Two grooves 17,18 that are respectively applied for O shape ring 19,20 are formed in the straight part 16.The second straight part 16 is transformed into convex shoulder 42 down.This convex shoulder 42 leads to the diameter three straight outer matrix section 22 bigger than the second straight outer matrix section 16.
