Description
Technical field
This utility model is related to valve field, particularly a kind of valve self-locking handle.
Background technology
In commercial production, processing activity, much place needs to use valve, and is required for arranging a confession on valve
People operates the handle that valve is turned on and off.Valve use during it is possible to can due to maloperation, external force collision etc. former
Because leading to handle to rotate, so mistake by valve opening（Or close）, once above-mentioned situation occurs, or the wave leading to resource
Take（Medium in pipeline is flowed out by valve）, or the normal operation of impact system（, by wrong closing, medium cannot for valve
Supply is realized by valve）, serious injures and deaths that can also result in personnel（The medium of toxic effect flows out from valve）.
Traditional valve door handle does not often possess auto-lock function, therefore, it is difficult to solving the above problems.
Content of the invention
This utility model is to solve the above-mentioned deficiency existing for prior art, proposing a kind of structure simply, design is skilful
Wonderful, rationally distributed, with low cost, easy to use it is ensured that valve will not be by the self-locking of wrong unlatching in the case of accident
Handle.
Technical solution of the present utility model is：A kind of valve with self-locking handle it is characterised in that：Described handle
Including the direct valve rod coupling part 1 being connected with valve rod and the handle portion 3 being cased with sheath 2, described valve rod coupling part 1 He
Between handle portion 3, structure is connected as one by connector 4, movable sleeve is connected to adapter sleeve 6 on connector 4, on adapter sleeve 6
It is provided with locking member 7, longitudinal section of described locking member 7 is L-type, the bottom of locking member 7 is inserted terminal 8, sticking department
The top of part 7 is pulling piece 9.
Offer along its axial arranged elongated slot 10 on described connector 4, be provided with spring 11 in elongated slot 10, described
One end of spring 11 be fixedly connected with connector 4, the other end of spring 11 is connected with adapter sleeve 6.
Lock hole 5 is additionally provided with described connector 4, described lock hole 5 is located at the top of adapter sleeve 6.
This utility model compared with the existing technology, has the advantage that：
The valve of this kind of version self-locking handle, for traditional and scarce existing for the handle of valve matched
Fall into, design a kind of structure that can be voluntarily locked after rotation, it, by the use of gravity or spring force as driving force, drives one
The individual locking member motion that can move, and finally allow the inserted terminal of locking member bottom insert the jack being opened on valve body
In, using alignment pin, position restriction can also be carried out to this locking member after locking simultaneously, thus fundamentally prevent
Because handle is voluntarily rotated by external force, leads to valve mistake to be opened（Or close）Situations such as generation, substantially increase peace
Quan Xing.And its processing technology is simple, cheap for manufacturing cost, it can be said that it possesses multiple advantages, is particularly suitable for
Popularization and application in the art, its market prospect is very wide.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the stereoscopic-state schematic diagram of this utility model embodiment.
Fig. 3 is the partial structural diagram of this utility model embodiment.
Specific embodiment
Below in conjunction with brief description specific embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows：A kind of valve
Use self-locking handle, it includes a valve rod coupling part 1, this valve rod coupling part 1 is directly connected with the valve rod in valve body,
It also includes a handle portion 4 supplying people to hold simultaneously, is socketed with sheath 2 outside handle portion 3, described valve rod connecting portion
Divide, between 1 and handle portion 3, structure connected as one by connector 4, movable sleeve is connected to adapter sleeve 6 on this connector 4,
It is that this adapter sleeve 6 can be moved with connector 4 along the axially opposing of connector 4, adapter sleeve 6 is provided with locking member
7, longitudinal section of this locking member 7 is L-shaped, and the bottom of locking member 7 is inserted terminal 8, this inserted terminal 8 be opened in valve
Jack on body is corresponding, and the top of locking member 7 is pulling piece 9, the main part of this pulling piece 9 and locking member 7
It is in substantially an angle of 90 degrees；On connector 4, axially offer elongated slot 10 along it, in this elongated slot 10, be provided with spring 11, this
One end of spring 11 is fixedly connected with connector 4, and the other end of spring 11 is then connected with adapter sleeve 6；Connector 4 is also opened
It is provided with lock hole 5, this lock hole 5 is located at the top of adapter sleeve 6.
Specific embodiment one：
To be installed on valve body without this kind of handle of elongated slot 10 and spring 11, allow valve rod coupling part 1 and valve rod phase
Even, pulling handle part 4 is capable of the on off state of application valve body when rotating；When needing swing handle part 2, operator first to
Upper lifting pulling piece 9, allows locking member 7 and adapter sleeve 6 together to rise, then swing handle part 4, and handle portion 4 moves to
Behind position（No matter moving to the position of valve opening state or the position of closed mode）, unclamp pulling piece 9, so in deadweight
Under effect, locking member 7 and adapter sleeve 6 will together move downward, until the inserted terminal 8 of locking member 7 bottom is inserted into out
In the jack on valve body, even if so handle portion 4 is subject to external force, because locking member 7 is directly plugged on valve body,
The opening/closing state of valve will not arbitrarily be changed；
This scheme is suitable for situation above valve body for the handle, mainly uses gravity to realize oneself of locking member 7
Dynamic lock out action.
Specific embodiment two：
This kind of handle with elongated slot 10 and spring 11 is installed on valve body, allows valve rod coupling part 11 and valve rod phase
Even, pulling handle part 4 is capable of the on off state of application valve body when rotating；Swing handle part 2 is needed to be that operator is controlled first
Pulling piece 9 processed, towards the direction motion of handle portion 4, allows locking member 7 and adapter sleeve 6 together to move, now spring 11 is pressed
Contracting, then swing handle part 4, after handle portion 4 motion puts in place（No matter moving to the position of valve opening state or closing
The position of state）, unclamp pulling piece 9, in the presence of spring 11, locking member 7 and adapter sleeve 6 are together towards the direction of valve body
Motion, until the inserted terminal 8 of locking member 7 bottom is inserted in the jack being opened on valve body, even if so handle portion 4 is subject to
To external force, put on because locking member 7 is directly plugged into send out, also will not arbitrarily change the opening/closing state of valve；
This scheme has no particular/special requirement for the relative direction between handle and valve body, and it mainly utilizes the bullet of spring 11
Power is realizing the automatic lock motion of locking member 7.
In addition, after locking member 7 is inserted jack, is realized the locking of handle, can also in lock hole 5 grafting alignment pin,
Due to the stop of alignment pin, locking member 7 cannot be extracted out from jack, and therefore handle also cannot be moved with respect to valve body,
Need to pull and during handle, alignment pin is extracted out, the mode according to upper segment description carries out operating.
