Description
Technical field
The utility model is related to ball valve positioning device technical fields, and in particular to the hand that a kind of pressing plate with ball valve coordinates
Handle.
Background technology
Ball valve is driven by valve rod and around the valve that ball valve axis rotates, available for the adjusting and control of fluid,
Wherein there is very strong shearing force between the V-type core of sealing V-type ball valve and the metal seat valve of pile-up welding hard alloy firmly, it is especially suitable
For the medium of fibre-bearing, small solid pellet etc., and multi-pass ball valve not only can flexibly control the interflow of medium on pipeline, divide
The switching of stream and flow direction, while also can close any channel and other two channel is made to be connected, this kind of valve is general in the duct
It should be horizontally mounted.The classification of ball valve includes pneumatic ball valve, electrical ball valve, manual ball valve.In China, ball valve is widely used
In industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steels, occupy in national economy
Very important status.Ball valve has the action being rotated by 90 °, and faucet body is sphere, has circular through hole or channel to pass through its axis
Line.Ball valve is mainly used to make the flow direction for cutting off, distributing and changing medium in pipeline, it is only necessary to the operation being rotated by 90 °
It can just be closed with the rotating torque of very little tight.Ball valve optimum switchs, stop valve uses, and V-type ball valve, electrically operated valve remove should
Pay attention to outside pipe parameter, it is also expressly noted that its environmental condition for using, since the electric device in electrically operated valve is an electromechanics
Equipment, use state are influenced very big by its use environment.
Handle of the prior art with pressing plate cooperation can cause to loosen in switching process to filler hold-down bolt, and
Easily jeopardize personnel's peace due to the security risk opened by mistake or accidentally line downstream is caused in pass under valve wide open either full off state
Entirely, economic loss is caused.
Invention content
The purpose of this utility model is to provide a kind of handle of the cooperation with pressing plate, the technical problem to be solved is that how
It avoids avoiding under valve wide open or full off state due to opening by mistake to loosening caused by filler hold-down bolt in switching process
Or the security risk for causing line downstream is accidentally closed, so as to avoid personnel and economic loss.
Handle described in the utility model with pressing plate cooperation includes handlebar and arc-shaped connecting rod, arc connection
Bar is fixed at one end end of handlebar；The end set of arc-shaped connecting rod has the first locking level and the second locking level, the
The intersection position of one locking level and the second locking level is provided with the first centre bore；The end set of first locking level has the first lock
Hole, the end set of the second locking level have the second lockhole.
First locking level and the second locking level is orthogonal.
Be provided with center screw on the pressing plate, center screw surrounding setting there are two countersunk bolts hole, two
Not countersunk bolts hole and a third lockhole.
Countersunk bolts hole is not matched respectively from different hexagon socket head cap screws into tolerance by two countersunk bolts holes and two
It closes.
The bolt head of hexagon socket head cap screw in the not countersunk bolts hole cooperatively forms position limiting structure with handle.
The technical solution of the utility model has the following advantages that：
It is described in the utility model reasonable with the handle arrangement of pressing plate cooperation, break conventional handle and filled with pressing plate positioning
It puts, 4 bolts hole of platen design are connect with valve body（Two of which is counterbore, and purpose does not allow it that handle drives is interfered to switch to be formed
It hinders）, hole and hexagon socket head cap screw are into tolerance fit, for pre-tightening filler；Another two bolt hole is then using not counterbore, hole and interior six
Corner bolt cooperatively forms limit function into tolerance fit, bolt head with handle.By the way that pressing plate is fixed on valve body, while
It can achieve the effect that pre-tighten filler, the bolt head of interior hexagonal then forms a switch limiting with corresponding root part of handle and makees
With this structure can be avoided effectively to loosening caused by filler hold-down bolt in switching process, and pressing plate and handle are provided with simultaneously
Lockhole position, user can lock pressing plate and handle under valve wide open or full off state, can to avoid opening by mistake or
Person accidentally closes and causes line downstream security risk, so as to avoid the damage of personnel or money.
Description of the drawings
Fig. 1 is the structure diagram described in the utility model with the handle of pressing plate cooperation.
Fig. 2 is the structure diagram of the pressing plate.
Fig. 3 is the vertical view of the handle coordinated with pressing plate.
Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1 to Figure 3, the handle described in the utility model with pressing plate cooperation includes handlebar 1 and arc is connect
Bar 2, the arc-shaped connecting rod are fixed at one end end of handlebar；The end set of arc-shaped connecting rod has the first locking
The intersection position of 3 and second locking level 4 of bar, the first locking level 3 and the second locking level 4 is provided with the first centre bore 5；First locking
The end set of bar has the first lockhole 2111, and the end set of the second locking level has the second lockhole 211.
First locking level 3 and the second locking level 4 is orthogonal.
Center screw 6 is provided on the pressing plate, center screw surrounding setting there are two countersunk bolts hole 19, two
