Abstract
The utility model relates to a split type butterfly valve, which is composed of a valve body which is split into two or three parts mutually consolidated, a butterfly plate piece, the butterfly plate and valve rod of which are cast into a whole, a valve seat and a handle. The surface of the butterfly plate piece that the butterfly plate and the valve rod are cast into a whole is sprayed (welded) with epoxy resin or alloy powder of different characteristics. The splitting angle of the valve body can be determined as required.
Description
A kind of valve body split type butterfly valve belongs to machinery manufacturing technology field.
Used butterfly valve adopts the equipped mode of structure of parts in addition such as whole valve seat and butterfly plate and valve rod etc. more at present, this structure, and manufacturing process is simpler, and the product precision guarantees easily.But large-diameter butterfly valve adopts this structure, all has valve body casting difficulty big, the equipped difficulty of valve rod and butterfly plate, and assembly precision is difficult to deficiencies such as assurance.
The split type butterfly valve promptly is that assembly precision is difficult to deficiencies such as assurances at present large-diameter butterfly valve manufacturing process difficulty commonly used is big, simultaneously the also suitable small-bore butterfly valve of its structural type or other form valve and a kind of valve of putting forward.
Its major technique feature of split type valve shows as: valve body becomes split type, and promptly a part of valve body is cemented on another part valve body, at the epoxy resin or the alloy powder of butterfly plate and valve rod butterfly plate spare cast in block surface spraying (weldering) different qualities.
Obvious advantages such as the split type butterfly valve has simple in structure, and flow is big, and flow resistance is little, and volume is little, and cost in light weight is low, and manufacturing is easy, keeps in repair also very convenient.
Accompanying drawing be the related split type butterfly valve most preferred embodiment structural representation of the utility model below in conjunction with accompanying drawing, further narrate its structure and working condition.
Valve body (5) is cemented on the valve body (2), and butterfly plate spare (4) then is butterfly plate and valve rod single piece cast in block, and is inclusive in the valve body.Valve handle (6) is connected with the axle head of butterfly plate spare (4).By the rotation of handle, the opening angle of decision butterfly plate, thus control is by the rate-of flow of butterfly valve.Split type butterfly valve shown in the present embodiment belongs to corrosion-resistant butterfly valve, so inboard build-in valve seat (3) in valve body (5), (2), the butterfly plate portion surface electrostatic painting epoxy resin or the corrosion resisting alloy powder of butterfly plate spare (4), valve seat (3) material can be neoprene, fluorine fourth rubber, anti-corrosive rubbers such as hydrogen rubber.The valve body of split type butterfly valve (5), (2) are can be by screw (1) fastening or adopt alternate manner such as pin fastening.
The dissection type butterfly valve, its valve body can be split into two partly or three part valve bodies according to the needs of making and using, and the subdivision angle can be decided as required.
Claims (2)
1, a kind of split type butterfly valve of being made up of valve body, butterfly plate, valve rod, handle, valve seat is characterized in that:
(1), valve body becomes split type, promptly valve body [5] is cemented on the valve body [2];
(2), the surperficial spray epoxy or the corrosion resisting alloy powder of butterfly plate and valve rod cast solid spare [4];
2, butterfly valve according to claim 1 is characterized in that valve seat (3) material can be neoprene, fluorine fourth rubber, anti-corrosive rubbers such as hydrogen rubber.
