Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to a kind of refrigerating machine copper ball valve sealing means.
Background technique
Ball valve is indispensable in Chemical Manufacture and daily life, and ball valve only need just can be closed tightly with revolving the operation that turn 90 degrees and very little moment of rotation.The main feature of ball valve is compact structure own, and easy operating and maintenance are widely used in every profession and trade, therefore external sealed in the valve has also been improved requirement.Conventional external sealed is by connecting with the UNF screw thread, and when being screwed into pad, screw when treating pressure vessel, medium might leak from the slit of screw.
Therefore, be necessary to provide a kind of ball valve outer sealing device.
Summary of the invention
The purpose of this utility model is to provide a kind of refrigerating machine copper ball valve sealing means of good seal performance.
In order to reach aforementioned purpose, a kind of refrigerating machine copper ball of the utility model valve sealing means, it comprises outside thread copper ball valve body, the nut that matches with the outside thread of described copper ball valve body, wherein this device also comprises pad and seal ring, outside thread place at described copper ball valve body offers groove, described pad is set in the described groove, and described seal ring is set in the described groove.
According to an embodiment of the present utility model, described nut is hexagon nut.
According to an embodiment of the present utility model, described seal ring is the O RunddichtringO.
According to an embodiment of the present utility model, the quantity of described seal ring is one.
According to an embodiment of the present utility model, the degree of depth of described groove extends on the described copper ball valve body the externally threaded end and directly locates.
According to an embodiment of the present utility model, described pad is the red copper pad.
According to an embodiment of the present utility model, the internal diameter of described pad and the external diameter of described groove are transition fit.
According to an embodiment of the present utility model, described groove is square groove or circular groove.
According to an embodiment of the present utility model, described seal ring is U-shaped seal ring.
According to an embodiment of the present utility model, the quantity of described seal ring is two.
The beneficial effects of the utility model: the utility model is offered groove by the outside thread place on the copper ball valve body, and at the sheathed pad of groove and seal ring, and then play good seal action, and pad can be repeated repeatedly to install and seal ring can not drop yet, good sealing effect.
Description of drawings
Fig. 1 is the utility model copper ball valve arrangement schematic representation;
Fig. 2 is the enlarged view at copper ball valve outside thread A place among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
See also Fig. 1 and Fig. 2, it is respectively the utility model copper ball valve arrangement schematic representation and A place enlarged diagram.As depicted in figs. 1 and 2, a kind of refrigerating machine copper ball valve sealing means, it comprises outside thread copper ball valve body 1, the hexagon nut 22 that matches with the outside thread 21 of copper ball valve body 1, wherein this device also comprises pad 3 and O RunddichtringO 4.
Please continue to consult Fig. 1 and Fig. 2, as preferred embodiment of the utility model, offering a width at outside thread 21 places of described copper ball valve body 1 is 5mm square groove 5, and wherein, the degree of depth of groove 5 extends to the footpath, the end of the outside thread 21 of described copper ball valve body 1.Pad 3 is set in the groove 5, and the external diameter of the internal diameter of described pad 3 and described groove 5 is transition fit, and wherein, described pad 3 is the red copper pad, and its thickness is 1mm.In other embodiments, this groove 5 can be circular groove or other shapes, and the width of this groove 5 and position can be decided according to actual conditions.In other embodiments, this pad 3 can also be other metallic shims, and its thickness can be decided according to actual conditions.
Wherein, O RunddichtringO 4 is set in the groove 5, and the quantity of the RunddichtringO of O described in the utility model 4 is preferably 1, and the position of O RunddichtringO 4 in groove 5 is preferably the outside that is positioned at pad 3.When copper ball valve body 1 is screwed in the refrigerating machine desired location, tighten hexagon nut 22 again, make pad 3 be close to hexagon nut 22, consider that actual working pressure is bigger, this moment, pad 3 can make O RunddichtringO 4 play seal action under the pressure of hexagon nut 22, and good sealing effect, pad 3 is not yielding.In other embodiments, described O RunddichtringO 4 also can be two, and be separately positioned on the both sides of pad 3, because actual working pressure is bigger, the pressure of 22 pairs of pads 3 of hexagon nut this moment transmits by the O RunddichtringO between hexagon nut 22 and the pad 3 indirectly, can make pressure disperse, directly the pressure phase specific pressure of pad 3 is reduced to some extent with hexagon nut 22, but these two O RunddichtringOs 4 also can play the better seal effect.In this embodiment, described seal ring 4 can be selected to bear the seal ring of bigger working pressure according to the working pressure of reality, and it can be the seal ring of U-shaped seal ring, y-type seal ring, V-shaped seal ring or other types.
Please continue to consult Fig. 1 and 2, when mounted, earlier red copper pad 3 is pressed in the groove 5, and then O RunddichtringO 4 is inserted in the groove 5 at outside thread 21 places of copper ball valve body 1, the copper ball valve is screwed in the position that refrigerating machine is set, tighten hexagon nut 22 again, at this moment, red copper pad 3 makes O RunddichtringO 4 play seal action under the pressure of hexagon nut 22.
The utility model is offered groove by the outside thread place on the copper ball valve body, and at the sheathed pad of groove and seal ring, and then plays good seal action, and can repeatedly repeat to install pad and seal ring can not drop yet, good sealing effect.
Above-mentioned explanation has fully disclosed embodiment of the present utility model.It is pointed out that and be familiar with the scope that any change that the person skilled in art does embodiment of the present utility model does not all break away from claims of the present utility model.Correspondingly, the scope of claim of the present utility model also is not limited only to previous embodiment.
