Description
Technical field
The utility model is related to valve member technical field, in particular, is related to a kind of three valve-types butterfly valve.
Background technology
Butterfly valve is called flap valve, can be used for the switch control of low pressure pipeline medium, refers to that valve (flap or butterfly plate) is circle
Disk, a kind of valve of open and close is reached around valve shaft rotation, and valve can be used to control empty gas and water, steam and various corruption
Corrosion medium such as mud, oil product, liquid metal and radiating medium etc., it is main on pipeline to play cut-out and throttling action, valve
Rotated around the axis of its own in valve body, so as to reach the purpose for opening and closing or adjusting, but because the manufacture material of valve is limited
System, after butterfly valve long-time use, valve is easily damaged, and is formed in one valve and top drive link more, maintenance cost mistake
Height, and for some special working environments, it is necessary in more accurate regulating butterfly valve fluid flow and flow velocity, existing butterfly
Valve not can solve these problems.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of three valve-types butterfly valve, and the valve of the butterfly valve is by three
Part is constituted, and easily replacing is repaired when being corroded, and cost is relatively low, and can improve the control essence of flow and flow velocity in butterfly valve
Degree.
Technical problem to be solved in the utility model is realized using following technical scheme.
A kind of three valve-type butterfly valves, it includes upper valve body, lower valve body and valve, and described valve is divided into three parts,
Respectively the first valve, the second valve and the 3rd valve, described every part valve upper and lower side are all fixedly connected with rotating bar, institute
Each the upper end rotating bar top stated is equipped with rotation handwheel, and three through holes, described rotation are provided with inside described upper valve body
Bar through inside through hole, being provided with axle sleeve between described rotating bar and through hole, described the first valve, the second valve and the 3rd valve
Door edge is equipped with sealing ring.
Further, the first described valve, the second valve and the 3rd valve are respectively positioned on inside lower valve body, described lower valve body
On be additionally provided with three rotation slots, described lower end rotating bar is respectively positioned on inside rotation slot.
Further, 8~10 centimetres are spaced between described rotation handwheel.
Each valve of this butterfly valve can individually be opened and closed, and will not influence each other each other, and staff can be independent
Or coordinate be opened and closed one or more valves, reach the purpose of accurate adjustment rate-of flow and flow velocity, in addition each valve and its
The part of connection can individually take out maintenance and change.
Compared with the prior art, the beneficial effects of the utility model are embodied in：
Butterfly valve valve is divided into the first valve, the second valve and the 3rd valve, and each valve side by the utility model
Edge with the addition of sealing ring, it is ensured that on the premise of sealing is not influenceed, and reach accurate adjustment rate-of flow and flow velocity and side
Just the purpose of replacing is repaired.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that utility model is realized are easy to understand, below
With reference to being specifically illustrating, the utility model is expanded on further.
As shown in figure 1, a kind of three valve-types butterfly valve, it includes upper valve body 4, lower valve body 1 and valve, and valve is divided into three
Part, respectively the first valve 8, the second valve 9 and the 3rd valve 2, rotating bar is all fixedly connected with per part valve upper and lower side
3, each top of upper end rotating bar 3 is equipped with rotation handwheel 5, and three through holes are provided with inside upper valve body 4, and rotating bar 3 passes through through hole
Inside, is provided with axle sleeve 6 between rotating bar 3 and through hole, the first valve 8, the second valve 9 and the edge of the 3rd valve 2 are equipped with close
Seal 7, the first valve 8, the second valve 9 and the 3rd valve 2 are respectively positioned on inside lower valve body 1, and three rotations are additionally provided with lower valve body 1
Groove, lower end rotating bar 3 is respectively positioned on inside rotation slot, and 8~10 centimetres are spaced between rotation handwheel 5, facilitates staff manual
Rotate.
When staff uses, can be according to the need of work of butterfly valve, rationally the first valve 8 of opening and closing, the second valve 9 and the
Three valves 5, carry out the flow and flow velocity of medium in precise control butterfly valve, and valve long-term work is in Korrosionsmedium (such as mud, oil
Product, liquid metal and radiating medium etc.) when receiving damage, the valve of the part that is damaged can be individually replaced to save economy
Cost, it is unspoiled to be continuing with.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
