Description
Technical field
A kind of locking mechanism for the valve being controlled the present invention relates to fluid medium, belong to fluid control valve neck
Domain.
Background technology
In fluid control valve field, the main function that valve rises in pipeline is the flow for controlling medium, and some are crucial
Property valve be even more to play vital effect, therefore, proper, safe operation and control should be carried out to valve.In actual life
In production, the place of a large amount of pipelines is disposed with, is not often to have professional to be guarded, if by layman to pipeline
In valve carried out illegal operation, it is small, bring huge economic loss, then cause serious security incident greatly and cause people
Member's injures and deaths.Therefore, proposing the concept of valve lock in valve industry, valve lock is exactly to prevent that it is improper that people from being carried out to valve
Operation, valve opening and closing state is carried out to the locking of rational safety.
The lock mode of valve opening and closing state, it can be handwheel and valve body (or its connector, such as bonnet) locking, also may be used
To be to lock valve rod and valve body (or its connector, such as bonnet).
In existing valve opening and closing state lock-in techniques：Early stage has to be locked together most on valve handle with iron chains and valve body
Straightforward procedure, due to too simple and unreliable, seldom use.
There are one disk-shaped part of setting, referred to as locking wheel on valve rod in recent years, on the cylindrical outer surface of locking wheel
Process dozens of to divide equally in the V-groove of circumference, with setting an interior hexagonal tapered end tightening on the relatively-stationary part of valve body
Screw is revolved the conical end of interior hexagonal tapered end holding screw with inner hexagon spanner, it is necessary to when being locked to valve opening and closing state
Enter in the V-groove of locking wheel, reach and line-locked purpose is entered to valve opening and closing state.This locking mechanism has a disadvantage that：
1st, the active force of interior hexagonal tapered end holding screw is by the axis of locking wheel, and lock-out state is unreliable, lock-out state
Shi Xuandong valve rods, locking wheel contact point can internal hexagonal tapered end holding screw contact form shearing force, in shearing can cause repeatedly
Hexagonal tapered end holding screw damages；
2nd, inner hexagon spanner commercially can arbitrarily be bought, and have the people sabotaged or for certain purpose, can be convenient
Wrongful operation is carried out to valve.
The content of the invention
The present invention will realize a kind of open/close states for being capable of positive lock valve, locking device turn valve in lock-out state
Bar, the abrasion very little of working face, non-easy damaged, configures private key, non-dedicated key can not change locking valve state
A kind of locking mechanism of valve.
The technical solution adopted for the present invention to solve the technical problems is：
1st, the locking device for valve designs a platform, and upper and lower is flange form part, the several interior hexagonals of two flanges
Fillister head screw connects, middle to be supported with the end face in a sleeve pipe and Step Shaft stage casing, the length phase in sleeve pipe and Step Shaft stage casing
Deng it is highly a definite value to make the cylindrical cavity among two flanges.
2nd, comprising a locking wheel that can be rotated with valve rod, driving parts are used as by the use of general flat key.
3rd, scheme one：Comprising a pair of symmetrical ratchets, two ratchets all have auto-lock function in lock-out state, one
For preventing locking wheel from rotating clockwise, another is used to prevent locking wheel from rotating counterclockwise, and the ratchet is a lever class zero
Part, passive side are the flank of tooth and tooth body of ratchet, and centre is a cylindrical hole, and the Step Shaft for being positioned with it coordinates.
4th, scheme two：Comprising a pair of symmetrical ratchets, two ratchets all have auto-lock function in lock-out state, one
For preventing locking wheel from rotating clockwise, another is used to prevent locking wheel from rotating counterclockwise, and the ratchet is a lever class zero
Part, passive side are the flank of tooth and tooth body of ratchet, and centre is a cylindrical hole, and the Step Shaft for being positioned with it coordinates, in master
One cylindrically coiled spring is set on dynamic side, and the pressure of spring is to tend to make two ratchets rotate to lock-out state.
5th, among two ratchet cylindrical holes, an axle is set by the positions of valve rod axis, wherein chamfered edge in section, attack spiral shell
Line, hexagon socket cap head screw or interior hexagonal flush end holding screw are installed, as the part for promoting ratchet to rotate when locking.
6th, scheme one：Turn hexagon socket cap head screw clockwise, its screw thread end face head on two ratchets and open locking device,
Turn hexagon socket cap head screw counterclockwise, its cylindrical end end face head on two ratchets and do lock out action, and two ratchets stretch into locking wheel
V-groove in, realize the locking to valve opening and closing state.
7th, scheme two：Hexagonal flush end holding screw in turn clockwise, its screw thread end face head on two ratchets and open locking dress
Put, hexagonal flush end holding screw in turn counterclockwise, cylindrically coiled spring heads on two ratchets and does lock out action, and two ratchets stretch into lock
In the V-groove of fixed wheel, the locking to valve opening and closing state is realized.
8th, using prior art ZL201220456015.5《Valve differential pressure adjusting device》In " stationary fit is mounted with one in hole
Individual straight pin, need to could realize regulation with the special inner hexagon spanner with mesopore ", applied to the present invention, justify in interior hexagonal
One straight pin of installation, non-dedicated key can not change valve in the interior hexagonal of chapiter screw or interior hexagonal flush end holding screw
Lock-out state.
Present invention advantage possessed compared with prior art and positive role：
1st, the technology calculating for being not necessary to complexity can complete design；
2nd, the valve being controlled applied to fluid media (medium), the open/close states of energy positive lock valve；
3rd, private key is configured, non-dedicated key can not change the state of locking valve；
4th, two ratchets all have auto-lock function in lock-out state.
