Description
Technical field
The utility model relates to a kind of butterfly valve, specifically a kind of plough groove type fire-fighting butterfly valve belongs to fire protection pipeline machinery
Part field.
Background technique
It is each used in from simplest shut-off valve to extremely complex robot control system(RCS) for the valve of fluid control systems
Kind valve, kind and specification are quite various, and valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil
The flowing of the various types fluid such as product, liquid metal and radiating medium, butterfly valve are a kind of most common opening and closing valves, utilize flashboard
The medium in pipeline is connected or is truncated, it allows to use as shutting off, and butterfly valve can more intuitively show valve opening degree, so as to
Corresponding measure can be taken in time in the aperture for remotely differentiating valve, opening and closing is reliable rapidly, therefore is commonly applied to fire-fighting system, but
It is because fluid resistance is big, sealing surface is relatively large by the erosion of medium, and opening and closing is harder, so easily causing erosion between sealing surface
And scratch, maintenance is relatively difficult, and in the case where valve body components are intact, only sealing surface slightly deforms existing butterfly valve
Or corrosion, valve cannot use, and leak is easy at valve rod and valve body contact.

The fluted disc is circular sheet-like structures, sets that there are two the plectrum being oppositely arranged, the fluted disc edges on the upper surface of the fluted disc
Equipped with saw-tooth grooves, the diameter of the valve body and fluted disc contact site, less than the diameter of fluted disc, it is deep that the valve rod passes through fluted disc
Enter to being arranged in the intracorporal butterfly plate of valve, the valve rod is polished rod, and the middle part of the butterfly plate is hollow cylinder, the valve rod insertion
In hollow cylinder in the middle part of to butterfly plate, the valve rod and butterfly plate are interference fitted by taper pin and fix position, and the taper pin runs through valve
Handle is fixedly installed in bar and butterfly plate, one end end of the valve rod outside valve body, and the handle includes main handle and secondary handle, institute
The forearm of secondary handle is stated by pin shaft hingedly with the lower section in the middle part of main handle, the postbrachium of the pair handle connect by spring with main handle, institute
The forearm for stating secondary handle is equipped with card point, and the edge that the card point is deep into fluted disc is equipped in saw-tooth grooves, the valve rod and valve
Body junction is equipped with sealing ring.
Further, the butterfly plate is the structure that colloid is wrapped up in internal steel plate outer surface.
Further, the sealing ring is " O " type sealing ring, is provided with 3 altogether, close-packed arrays are sleeved on valve rod.
Further, even application non-toxic epoxy coating on the valve interior wall.
Further, the body base uses plain base seat design identical with water pipe.
The utility model relates to a kind of plough groove type fire-fighting butterfly valve valve rod and valve body are reduced by the sealing ring added
Friction between contact surface, so that butterfly valve is more lightly not easy leak in switch, the encapsulated design of the entirety of butterfly plate is also the same
Reduce the friction and erosion between butterfly plate and valve body and medium, the effective service life for extending butterfly plate, valve interior wall spraying
Epoxy resin makes the abrasion-resistance of valve body higher, and the plain base design application of bottom is so that be not easy dirt heap occur in valve body
Product, so that the sealing of gate valve is relatively reliable.
The utility model is described in detail with reference to the accompanying drawings and examples.
