The technical problem of the utility model is realized through following technical scheme:
a quick-change long rod ball valve comprises a valve body, a valve cover, a ball valve core, a valve rod and a hand wheel, wherein the ball valve also comprises an extension rod; the hand wheel removable type install on extension bar top, this extension bar bottom removable type connection is on the valve rod, and hand wheel drive extension bar drives the spheroid case through the valve rod and realizes rotating to open and close, or the direct removable type of hand wheel is installed on the valve rod to drive the valve rod and drive the spheroid case and realize rotating to open and close.
The extension bar is externally provided with an extension sleeve which is sleeved and installed.
The bottom end of the lengthened sleeve is contacted with the top of the valve body, the top end of the lengthened sleeve is contacted with the hand wheel, and the lengthened sleeve is sealed inside.
The extension bar and the valve rod are positioned on the same axis.
The valve rod is provided with an exposed end extending out of the top of the valve body, and the extension rod or the hand wheel is detachably connected to the exposed end.
The exposed end and the top end of the extension bar are respectively provided with an external thread shaft for the hand wheel to be detachably installed.
The bottom end of the extension bar is provided with an internal thread hole, and the bottom end of the extension bar is detachably connected to the external thread shaft of the exposed end through the internal thread hole.
Compared with the prior art, the utility model is mainly characterized in that an extension bar is added on the ball valve; thus, when the ball valve is used in a special occasion with a closed installation position, the operation space can be enlarged by the extension bar only by detachably installing the hand wheel at the top end of the extension bar and detachably connecting the bottom end of the extension bar to the valve rod, and the hand wheel drives the extension bar to drive the ball valve core to realize rotary opening and closing through the valve rod, so that convenience is brought to the opening and closing operation of the hand wheel; when the ball valve is used in a common occasion with an open operating space, the extension bar can be removed and the ball valve can be directly used as a common ball valve; therefore, the design of the extension bar meets the use requirements of the hand wheel in special occasions or common occasions, the use mode is flexible, and great convenience is brought to the use of users.
Drawings
Fig. 1 is a schematic sectional view of the present invention.
Detailed Description
The embodiments of the present invention will be described in detail below with reference to the drawings.
As shown in figure 1, the valve comprises a valve body 1, a valve cover 2, a ball valve core 3, a valve rod 4, an exposed end 41, a hand wheel 5, an extension rod 6, an internal thread hole 61, an extension sleeve 7, a nut 8, an external thread shaft 9 and a double-channel O-shaped ring 10.
The utility model provides a quick change stock ball valve, as shown in figure 1, mainly relate to one kind and can be applicable to the airtight and narrow and small special occasion in operating space of mounted position and use, can be applicable to the pipeline valve that the open ordinary occasion in mounted position used as ordinary ball valve again, the main part of this ball valve all adopts the design preparation of environmental protection dezincification resistant DR copper material, its structure is by valve body 1, the valve gap 2 of seal installation at the valve body tip, the spheroid case 3 of rotary seal installation between valve body 1 and valve gap 2, through the vertical rotary seal of two way "O" type circle 10 valve rod 4 in valve body 1, and drive the valve rod and drive the constitution such as hand wheel 5 that spheroid case 3 rotated and opened and close this ball valve, this hand wheel 5 adopts zinc alloy die casting technology, surface electrophoresis design, guarantee whole outward appearance and use strength.
The valve rod 4 is provided with an exposed end 41 extending out of the top of the valve body 1, and the top end of the exposed end is provided with an external threaded shaft 9.
When the ball valve is suitable for being used in a special occasion with a sealed installation position, the ball valve also comprises an extension bar 6 and an extension sleeve 7, wherein the extension bar is made of a carbon steel galvanized material to ensure the use strength, and the extension sleeve is designed by a zinc alloy die-casting process; the bottom end of the extension bar 6 is detachably screwed on the external thread shaft 9 of the exposed end 41 through the internal thread hole 61, the extension bar 6 and the valve rod 4 are ensured to be positioned on the same axis, the external thread shaft 9 is also arranged at the top end of the extension bar 6, and after the hand wheel 5 is sleeved on the top end of the extension bar 6 through the mounting hole, the hand wheel 5 and the extension bar 6 can be fastened only by detachably screwing the nut 8; like this, hand wheel 5 drive extension bar 6 can drive spheroid case 3 through valve rod 4 and realize rotating and open and close, and also realize the extension through extension bar 6 and open and close to the operating space of ball valve has been enlarged, thereby brings the convenience for the operation of opening and close of hand wheel 5.
