Description
Technical field
This utility model relates to valve field, more specifically, it relates to a kind of flange form two-way hard seal butterfly valve.
Background technology
Butterfly valve, is a kind of regulation valve, and in being used for controlling pipeline, the flowing of all kinds fluid such as empty gas and water, steam, various corrosive medium, mud, oil product, liquid metal and radiating medium, is arranged on pipeline and plays cut-out and throttling action.The hand wheel rotating mode of existing butterfly valve can be divided into two kinds, and one is to hold handwheel rim, relies on the friction of hands and handwheel rim to drive the rotation of handwheel, and this mode can waste substantial amounts of inessential energy, and efficiency is low；Another kind is to promote the support bar on handwheel to drive handwheel, but the handwheel size of existing butterfly valve is less than normal, and the arm of force is shorter, needs a bigger power could drive hand wheel rotating.When running into pipe leakage, needing the manual adjusting handle of operator to realize the closedown of butterfly valve, this results in operator and spends more power rotating on handwheel, and wastes substantial amounts of manpower and time.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of labour-saving flange form two-way hard seal butterfly valve.
For realizing above-mentioned technical purpose, this utility model provides following technical scheme: a kind of flange form two-way hard seal butterfly valve, including handwheel rim, support bar, the sliding chamber consistent with support bar length direction it is provided with in described support bar, described sliding chamber opening communicates through handwheel rim and with the external world, described sliding intracavity sliding connection expansion link.
By such scheme, utilize the sliding chamber in support bar to accommodate expansion link, expansion link can be made to skid off by running through the sliding chamber opening of handwheel rim；When rotating handwheel, it being pulled out from sliding intracavity with hand-held firmly expansion link, expansion link skids off the extension as support bar from sliding chamber opening part, increases the arm of force, reduces the power rotated required for handwheel；When stop operating handwheel time, expansion link can be put back to sliding chamber, thus avoid wasting substantial amounts of manpower and time.
Preferably, the medial wall in described sliding chamber is provided with the chute consistent with support bar length, and described expansion link is provided with the slide block for coordinating with chute.
Being coordinated by such scheme, the chute on sliding cavity wall and the slide block on expansion link makes expansion link not produce rotation in sliding process, and the chute consistent with support bar length limits the extreme length that expansion link outwards skids off, and prevents expansion link entirety from skidding off and drops.
Preferably, described expansion link is provided with pulling block near the end of handwheel rim.
By such scheme, when rotating handwheel and needing to skid off expansion link, by pulling block can fast and convenient pull-out expansion link, time-consuming.
Preferably, described sliding chamber opening part is hinged with screening chamber lid.
By such scheme, after hand wheel rotating terminates, sliding intracavity put back to by expansion link, and in opening part hinged screening chamber, sliding chamber, lid covers in sliding chamber, prevents expansion link to be exposed to for a long time in external environment condition and moisture generation rust corrosion.
Preferably, described screening chamber lid jointed shaft is provided with offer and hides chamber lid to the torque spring of side, sliding chamber torsion.
By such scheme, when sliding chamber regained by expansion link, closing and hide chamber lid, torque spring makes lid laminating sliding chamber, screening chamber opening part, prevents from skidding off beyond expansion link.
Preferably, the surface of described screening chamber lid is provided with the projection being made up of soft material.
By such scheme, when rotating handwheel, hold the projection being easy to capture on the cap surface of screening chamber and drive screening chamber lid hide sliding chamber opening or make sliding chamber unimpeded with the external world.
Preferably, described projection is made up of soft material.
Pass through such scheme, when finger acts on the lug surface being made up of soft material, lug surface deforms upon, increase the contact area of finger and projection, improve frictional force between the two, make not produce during finger grip projection slip, and soft material makes finger promote with bump contact feel, increases and grips comfort level.
Preferably, it is provided with the through hole along its axial distribution in described expansion link.
The quality of itself can be reduced by the through hole arranged in technique scheme, expansion link, reduce and pull the power required for expansion link.
Preferably, described pulling block is rotationally connected with expansion link.
By technique scheme, after expansion link is regained sliding chamber, projection, by being rotated in through hole, saves space, it is simple to hide the Guan Bi of chamber lid.
In sum, this utility model has the advantages that the laborsaving convenience of hand wheel rotating on this flange form two-way hard seal butterfly valve, rotating manner scientific and efficient, and without operation can be completed by third party's instrument, reduce the physical fitness requirement to operator, improve work efficiency.
