Description
Technical field
The present invention relates to valve mechanism technical fields, and in particular to a kind of valve handle for preventing maloperation.
Background technique
It in production scenes such as petrochemical industries, needs using a large amount of valves, to reach laborsaving purpose, usually using valve handle
Carry out valve switch operation.Currently, generalling use " F " type valve handle carries out valve switch operation, when operation, opens " F " handwheel
Oral area point is stuck on valve handle ontology, and the extension bar by pulling " F " handwheel drives valve handle rotation, reaches controlled valve
Purpose.But stress point need to be replaced repeatedly when carrying out valve switch operation, needs more wide operating space, and be easy
The phenomenon that now skidding, operational safety is poor, use it is cumbersome, and operate it is time-consuming and laborious, there are also maloperations to move direction
A possibility that opposite, occurs.
Authorization Notice No. is that the utility model patent of CN205674099U discloses what a kind of and valve handle was used cooperatively
Valve handle, including fixture, extension bar, ratchet head and latch, ratchet head are connected directly with extension bar one end, and are fastened on fixture
Connecting hole in, one end of latch is fixed on fixture, the other end to far from fixture direction extend, be used for clamping valve rod.Make
Used time latch is stuck in the valve rod of valve, drives ratchet head come rotating valve by rotational handle, to realize the switch of valve.It lacks
Falling into is that fixture is fixedly connected with ratchet head, non-dismountable, but the size of valve handle is not quite similar in practical application, leads to latch
It is connect with valve handle unstable, different model valve handle can not be common to, use inconvenience, the scope of application is small.No
It is suitable for the open and close valve in narrow space.
Summary of the invention
It is an object of the present invention to overcome defect existing in the prior art, provide a kind of structure it is simple, it is easy to use,
Can controlled valve within the scope of narrow space, but also can be to avoid a kind of valve for preventing maloperation to cause the accident by maloperation
Door handwheel.
To achieve the above object, the technical scheme is to design a kind of valve handle for preventing maloperation, the valves
Door handwheel is respectively used to the opening and closing of valve, each handwheel is respectively equipped with inner ring and outer rings, the internal diameter of outer ring there are two setting
Greater than the outer diameter of inner ring, it is evenly equipped with several ratchets on the outer wall of inner ring, the inner wall of inner ring is outer by connecting rod and center ring
The inner wall of wall connection, center ring is connect by connecting key with valve rod, and one end of valve rod is connect with valve plate, uniformly distributed on the inner wall of outer ring
There are several radial blind holes, radial blind holes are provided with the pawl with ratchet cooperation, set between pawl and the bottom hole of radial blind holes
There is spring, the ratchet orientation on two of them handwheel endocyclic outer wall is opposite.
In order to ensure the switch smooth operation of valve, reduce the abrasion to ratchet, pawl, preferred technical solution
It is that the radial blind holes are at least provided with three.
In order to ensure the switch smooth operation of valve, reduce the abrasion to ratchet, pawl, further preferred technology
Scheme is to be equipped with 4~6 in institute's radial blind holes.
For the ease of the processing of blind hole and the raising of efficiency easy to process, further preferred technical solution is in addition, institute
Stating radial blind holes is to be equipped with screw thread in macropore one end of radial ladder hole, and setting threaded macropore one end, to add screw stifled
Head, if the outer wall side of outer ring is arranged in threaded macropore one end.
For the ease of the installation and fixation of spring, further preferred technical solution in addition, the pawl bottom and
The bottom of blind hole is respectively equipped with spring base.
It is further excellent in order to improve the processing and manufacturing efficiency of valve handle, while for the ease of using and preventing maloperation
The technical solution of choosing is cast on or off and direction arrow symbol on the surface of casting in addition, the outer ring and inner ring are casting.
For the ease of the processing of blind hole and the raising of efficiency easy to process, further preferred technical solution is in addition, institute
Stating the screw thread in radial blind holes or stepped hole and stepped hole macropore on outer ring is on casting by being machined into.
Work efficiency rate is built for the ease of improving, it is ensured that processing quality, while can be obtained just after being worn for the ease of ratchet
Prompt maintenance with changing, further preferred technical solution in addition, ratchet, center ring on the endocyclic outer wall inner wall and keyway
By being machined into.
Work efficiency rate is built for the ease of improving, it is ensured that processing quality, while can be obtained just after being worn for the ease of ratchet
Prompt maintenance is with changing, and further preferred technical solution is in addition, the ratchet on the endocyclic outer wall is inserted ratchet, in ratchet
Side be equipped with dovetail convex block or T shape convex block, the dovetail cooperated with dovetail convex block or T shape convex block is equipped on the outer wall of inner ring and is inserted
Slot or T shape slot.
For the ease of the switch operation to handwheel, further preferred technical solution is in addition, on the outer wall of the outer ring
Equipped with several evagination handwheels.
The advantages and beneficial effects of the present invention are: the valve handle for preventing maloperation has, structure is simple, uses
It is convenient, can controlled valve within the scope of narrow space, but also can be to avoid causing the accident because of maloperation the features such as.
The handwheel can only execute its it is corresponding open the door or door-closing operation, cannot can valve opening door again can closing valve, substantially
Avoid the possibility of maloperation.Open valve handle, be used in valve opening operation handwheel, in appearance using green japanning with
And the typefoundings such as "ON" " open " are distinguished, and are carved with the valve opening door arrow logo rotated counterclockwise.Functionally, to avoid missing
Operation, opens valve handle using left-handed ratchet, and ratchet skids under the action of the spring with pawl when reverse rotation, it is therefore an objective to hold
When row maloperation (i.e. with the operation for opening valve handle execution closing valve), valve rod is not able to rotate, and is latched maloperation.Equally, the hair
Bright closing valve handwheel carries out area using typefoundings such as red japanning and "Off" " close " in appearance using dextrorotation ratchet
Not, and it is carved with the arrow logo for rotating clockwise valve opening door.Functionally, to avoid maloperation, it is therefore an objective to execute maloperation
When (executing the operation of valve opening door with closing valve handwheel), valve rod is not able to rotate, and is latched maloperation.By respectively using tool two
There are the valve opening door of blocking function and the handwheel of closing valve, guarantee the correct execution of operation, avoids maloperation bring economy effect
Benefit and social effectiveness loss.
