Abstract
The utility model discloses a lockable ball valve with inner threads, which comprises a valve body (1), a valve seat (2), a ball valve core (3) installed in the valve seat (2), a valve rod (4) in linkage with the ball valve core (3) and a hand shank (5) arranged on the valve rod (4). A positioning block (6) is fixedly sleeved on the valve rod (4), one side of the positioning block (6) is provided with a gap (6a) for the end of a locking screw (7) to be inserted into, the locking screw (7) with the axis perpendicular to the valve rod (4) is in threaded matching with the valve body (1), and the tail portion of the locking screw (7) is provided with a lock hole for a special key to be inserted into. The lockable ball valve is suitable for connection of a gas inlet of a gas meter, is also suitable for liquid, and has no limitations to the flowing direction of a medium. When the locking screw is omitted, a locking function disappears. The lockable ball valve with the inner threads has the advantages of being simple in structure and ingenious in design, and centralized and unified management of gas systems is facilitated.
Description
Technical field
The utility model relates to a kind of internal thread ball valve, specifically, but is a kind of internal thread locking ball valve that is used on the natural gas meter.
Background technique
The internal thread ball valve is applicable to the combustion gas medium, uses very extensive at present in the world.Common internal thread ball valve as shown in Figure 1 by valve body 1, valve seat 2, is installed in spheroid spool 3 compositions such as grade in the valve seat 2.Spheroid spool 3 is connected with valve rod 4 and handle 5, and gland 9 is equipped with in handle 5 belows, and sealing gasket 10 is equipped with in gland 9 belows.The internal thread ball valve of this structure, in the combustion gas erecting bed, who can both open, and is unfavorable for management, especially at new residential building.
The model utility content
The utility model technical problem to be solved provides a kind of ball valve can safety after installing locking, be beneficial to the fuel gas ball valve of gas company management, can't open under the situation of special tool not having, even it is also not all right to remove handle.
For solving above technical problem; But a kind of internal thread locking ball valve that the utility model provides; The valve rod (4) that comprises valve body (1), valve seat (2), is installed in spheroid spool (3) in the valve seat (2), links with spheroid spool (3) and be contained in the handle (5) on this valve rod (4); Key is: said valve rod (4) is gone up fixed cover positioning block (6) is housed; One side of positioning block (6) is provided with the breach (6a) that supplies lock bolt (7) end to insert, and axis normal is in the lock bolt (7) and said valve body (1) screw-thread fit of valve rod (4), and the afterbody of said lock bolt (7) has the lockhole that supplies private key to insert.
Rotatable handle drives positioning block and rotates together, when the breach of positioning block turns to the lock bolt position, inserts in the lockhole of lock bolt through private key and turns lock bolt, the end of lock bolt is snapped in the breach of positioning block ball valve is pinned; After this, must turn the breach that lock bolt makes the end of lock bolt withdraw from positioning block through private key could open ball valve, after ball valve pins, can not unblank even take away handle.This ball valve that ends function with lock can make things convenient for the centralized and unified management of gas burning system.
As preferably; Said valve body (1) is provided with the outside thread that is connected with valve seat (2); Valve seat (2) is provided with corresponding with it internal thread; Valve body (1) and valve seat (2) are pressed with seal ring (11) through being threaded together between valve body (1) and valve seat (2), to improve the sealing effect of ball valve.
The internal thread ball check valve that the utility model provides is applicable to the connection of gas meter suction port, also is applicable to liquid; To the not restriction of the flow direction of medium, after removing lock bolt, latch functions also disappears; Have simple in structure, design characteristics cleverly, be convenient to the gas burning system centralized and unified management.
Description of drawings
Fig. 1 is the structural representation of common internal thread ball valve.
Fig. 2 is the schematic representation of the utility model opening state.
Fig. 3 is the schematic representation of the utility model lockup state.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
But like Fig. 2, internal thread locking ball valve shown in Figure 3, by valve body 1, valve seat 2, spheroid spool 3, valve rod 4 be contained in handle 5 on the valve rod 4, nut 8 etc. and form.Spheroid spool 3 is contained in the valve seat 2, and spheroid spool 3, valve rod 4 and handle 5 are connected.Gland 9 is equipped with in handle 5 belows, and sealing gasket 10 is equipped with in gland 9 belows.
Fixed cover is equipped with positioning block 6 on the valve rod 4, and a side of positioning block 6 is provided with the breach 6a that supplies lock bolt 7 ends to insert.Have radial screw bore on the valve rod 1, axis normal is arranged in the radial screw bore of valve rod 1 and valve body 1 screw-thread fit in the lock bolt 7 of valve rod 4, and the afterbody of lock bolt 7 has the lockhole that supplies private key to insert.
Shown in Figure 2 is opening state, and the end of lock bolt 7 is positioned at outside the positioning block 6.Like Fig. 3; Rotatable handle 5 drives positioning block 6 and rotates together; When the breach 6a of positioning block 6 turns to lock bolt 7 positions, insert in the lockhole of lock bolt 7 through private key and turn lock bolt 7, the end of lock bolt 7 is snapped among the breach 6a of positioning block 6 ball valve is pinned; After this, must turn the breach 6a that lock bolt 7 makes the end of lock bolt 7 withdraw from positioning block 6 through private key and just can come back to opening state shown in Figure 2.
Claims (2)
1. but internal thread locking ball valve; The valve rod (4) that comprises valve body (1), valve seat (2), is installed in spheroid spool (3) in the valve seat (2), links with spheroid spool (3) and be contained in the handle (5) on this valve rod (4); It is characterized in that: said valve rod (4) is gone up fixed cover positioning block (6) is housed; One side of positioning block (6) is provided with the breach (6a) that supplies lock bolt (7) end to insert; Axis normal is in the lock bolt (7) and said valve body (1) screw-thread fit of valve rod (4), and the afterbody of said lock bolt (7) has the lockhole that supplies private key to insert.
