Description of the drawings
Fig. 1 is the structural representation of a specific embodiment of the present utility model；
Fig. 2 is the A-A direction views of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described further.
Referring to Fig. 1-2, the utility model discloses a kind of reducible balanced valve, including upper and lower valve body, described upper and lower
Valve body is connected, and is provided with valve element 1 in the lower valve body 2, and the valve element connection drives one end of valve rod 7, the driving valve rod another
One end penetrates the upper valve body 3 and connects actuator 6, and the actuator is any type of drive of driving handwheel or driving handle etc.
Moving part.
The driving valve rod is additionally provided with resetting means, and the resetting means includes reseting disk 5, generally, the reseting disk
Outline is gear shape, and less using modulus, and the more gear of the number of teeth is increasing the accuracy and precision of reset, and institute
The stroke height up and down of the thickness of reseting disk more than the reseting disk is stated, is additionally provided with below reseting disk for limiting the reset
The back-up ring of disk stroke.The reseting disk is sheathed on the driving valve rod and is provided with supporting locking device 4, the locking device
The key coordinated including the lock that is arranged on the upper valve body and with the lock, inserts a key in the teeth groove of reseting disk to limit
The rotation of reseting disk.Preferably, the lock adjusts lock for magnetic, and the key is magnetic key.The locking device can be with
For any type of locking members such as the lock-screw or locking bearing pin of reseting disk rotation can be limited, disclosure satisfy that restriction reseting disk turns
Dynamic purpose.
The driving valve rod is provided with outside the closely-pitched external screw thread being connected with the reseting disk and the coarse thread being connected with the valve element
Screw thread, the endoporus of the reseting disk are provided with reseting disk internal thread, and the reseting disk internal thread is closely-pitched internal thread, the reseting disk
It is that movable fine thread is connected with the driving valve rod, not only bulk is little but also self-locking property good for fine thread, not only
The overall structure size of balanced valve can be reduced, it can also be ensured that reseting disk can turn with driving valve rod in not locking state
Dynamic, it is relatively fixed with valve rod is driven, final realization resets.
The valve element is provided with valve element internal thread, and the valve element internal thread is coarse thread internal thread, the valve element and the driving
Valve rod is that movable coarse thread connects, and coarse thread bonding strength is high, it can be ensured that the reliability of connection so that valve element is opened and closed
Close relatively reliable.
The utility model, can drive drive screw by revolving outer actuator while rotating, so as to pass through drive screw
Coarse thread connect band movable valve plug between valve element is moved up and down, and realizes the opening and closing of valve and the regulation of openings of sizes.
In normal use, it is not required to locking member（Can be key, lock-screw or locking bearing pin etc.）Insertion reseting disk
Teeth groove in so that reseting disk is rotated with drive screw in the presence of fine thread frictional force, and is not occurred upper and lower
Relative displacement.
When needing valve closing, and being reset to original open position when opening next time, it is necessary first to operation locking
Part is caused in the teeth groove of locking member end insertion reseting disk, so as to limit the rotation of reseting disk, now need to make reseting disk with described
Back-up ring is fitted close, and reseting disk will neither be rotated nor be moved up and down；Then rotate driving valve rod by actuator, so as to band
Movable valve plug moves down closing valve, while reseting disk occurs relative displacement in the presence of screw thread and locking member, moves up
To a certain position, now reseting disk number turn-taked with respect to drive screw drive screw relative with valve element is turn-taked several identical；Need
When valve is reopened, opposite direction rotary drive, now valve element move up Open valve, reseting disk is moved down, when
When reseting disk is re-moved to position close-fitting with the back-up ring, reseting disk is completely restricted, and now valve element is also reset to
Original open position.
Enforcement described in the utility model patent is for the ease of the those skilled in the art it will be appreciated that and application
The utility model, resetting means of the present utility model are not limited to the version of valve body, can match somebody with somebody with the valve of arbitrary structures and size
