Description
Technical field
The present invention relates to a kind of butterfly valve, a kind of butterfly valve with locking functions handle.
Background technology
Butterfly valve is again flap valve, is the regulation valve of a kind of simple in construction, can be used for the on-off control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, rotates a kind of valve reaching to open and close around valve shaft, and valve can
For controlling all kinds such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium
The flowing of fluid.Pipeline acts primarily as cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Axis around himself rotates, thus reaches to open and close or the purpose of regulation.
Butterfly valve is used in the middle of various pipeline widely, and the existing butterfly valve in market typically uses pin to connect valve shaft and butterfly
, when valve shaft rotates, a certain degree of relative motion i.e. between valve shaft and butterfly plate, can be there is in plate, although this relative motion is small,
But the not only operation of inconvenient valve, also can make pin accelerate to damage, between selling between pin-and-hole in the friction of pin-and-hole simultaneously
Gap also makes to necessitate at pin-and-hole opening part installing sealing device, and otherwise shank is by bearing the corrosion of pipeline liquid for a long time, adds
The damage of speed shank.
Owing to the connecting hole of current butterfly valve is circular, the most existing butterfly valve being shaped with circular connecting hole can only be specific
, use on special pipeline or equipment, meanwhile, the existing butterfly valve being shaped with circular connecting hole can not meet external some
The standard of the pipeline of country, therefore greatly limit the use of butterfly valve, also gives and use enterprise to bring great inconvenience.
And existing Handle of butterfly valve is due to can not be the most locked, it is impossible to guaranteeing that butterfly valve is failure to actuate, this brings to butterfly valve work
Inconvenience, brings hidden danger also to the safety of operator.
Summary of the invention
It is an object of the invention to provide a kind of butterfly valve with locking functions handle, described butterfly valve not only ensures valve shaft and butterfly
Without relative motion between plate, good seal, and be applicable to the pipeline of multiple standards, simultaneously this Handle of butterfly valve can with locking, from
And ensure that the operation of butterfly valve is accurate.
For achieving the above object, the technical solution used in the present invention is: a kind of butterfly valve with locking functions handle, including
Valve shaft, butterfly plate, valve body, valve shaft is inserted in valve body and butterfly plate, is connected by expansion pin is fixing, expansion pin between valve shaft with butterfly plate
Be inserted in valve shaft and butterfly plate, described expansion pin include the shank stretching out butterfly plate in two ends and the nut being arranged in pairs, elastomeric pad,
Gland and expansion sleeve, the radius in the middle part of described shank, more than the radius at shank two ends, is transition in the middle part of shank and between two ends
Frustum, what transition frustum was arranged on valve shaft and butterfly plate coordinates place；Expansion sleeve, gland, elastomeric pad are sequentially sleeved at from inside to outside
Transition frustum is to shank end, and nut is screwed onto shank outermost end；Described butterfly valve also includes Packing seat and is set in valve shaft
Go up and be fixedly connected on the gland of valve body upper end；Described valve shaft upper end is Step Shaft, and gland is blocked by Packing seat
The step of valve shaft upper end, the valve shaft lower end of described butterfly valve is provided with split snap ring, and split snap ring protrudes the part quilt of valve shaft lower end
Bottom end cover overlays on the lower surface of valve body.
The upper and lower equal specular in both sides of described valve body is shaped with engaging lug, is all shaped with connecting hole, institute on each engaging lug
Stating connecting hole is slotted hole, and the outer surface of butterfly plate is fixedly mounted with a rubber layer.
Described butterfly valve upper end arranges top flange, and described top flange is provided with stop dial, and stop dial is installed
Having handle, described handle to arrange upper handle and lower handle, the forearm of described lower handle is loaded in the middle part of upper handle by bearing pin hinge
Lower section；The cephalic par outer rim top of upper handle is shaped with tuning drive gear, is radially shaped with valve shaft hole in the cephalic par of upper handle；Described
The postbrachium of lower handle is connected with upper handle by spring, and the top of the forearm of lower handle is shaped with card point, between bearing pin and spring
Upper handle on be shaped with a upper handle lock hole, the lower handle corresponding with upper handle lock hole is shaped with handle locking
Hole.
As a further improvement on the present invention, it is symmetrically arranged with arc between the upper and lower engaging lug in described valve body both sides to strengthen
Muscle.
As a further improvement on the present invention, described valve shaft top is provided with 4 expansion pin and is connected with butterfly plate, and valve shaft bottom sets
2 expansion pin are had to be connected with butterfly plate.
The invention has the beneficial effects as follows:
1. using expansion pin to fix between butterfly plate with valve shaft to be connected, the guide of expansion pin expands when mounted, makes pin and pin
Form blind-mate between hole, it is achieved that the sealing between pin and pin-and-hole, also make valve shaft and butterfly plate be fixedly connected into one, protect
Demonstrate,prove without relative motion between valve shaft and butterfly plate, thus pipeline fluid can have been avoided to enter without arranging sealing at the opening part of pin-and-hole
Entering pin-and-hole causes shank to corrode, and it also avoid and there is the shank abrasion that relative motion causes between valve shaft and butterfly plate.The two of valve shaft
End is provided with gland, bottom end cover limits the motion of valve shaft, therefore during stress, axle system rigidity does very well, beneficially valve
Open and close and sealing condition is good；
2. the lateral symmetry of valve body described in is provided with engaging lug, and the connecting hole on engaging lug is slotted hole, and this butterfly valve is permissible
It is applicable to multiple standards pipeline, easy for installation, expand the range of this butterfly valve；
3. butterfly valve described in arranges handle, and upper handle lock hole is connected with lower handle lock hole, can be by inserting a pin
Nail or other adamants and then lock this handle, prevent this Handle of butterfly valve generation action, thus ensure that the operation of butterfly valve is accurate.
