Description
Technical field
The utility model belongs to valve technology field, and in particular to a kind of pipeline butterfly-type valve.
Background technique
Currently, the higher pipeline valve of utilization rate mostly uses ball valve in the market, the opening and closing element of ball valve is one
A sphere, is rotated by 90 ° around the axis of valve rod the open and close to realize valve by sphere, and that there are structures is multiple for ball valve
Miscellaneous, quality weight, opening speed is slow, adjustable extent is small, high production cost, maintenance and the big defect of replacement difficulty.
Summary of the invention
That the purpose of this utility model is to provide a kind of structures is simple, opening and closing speed is fast, adjustable extent is big, it is cheap and
Pipeline butterfly valve easy to maintenance.
In order to achieve the above objectives, technical solution adopted in the utility model are as follows:
A kind of pipeline butterfly-type valve, including valve body, valve seat, handle and flanged pipe, the valve body include valve rod and spool,
Valve rod passes through spool group and is integrally formed, and spool is located in flanged pipe；The valve seat includes upper flange plate, middle ring flange and lower flange
Disk, upper flange plate, middle ring flange and lower flange are successively sleeved on flanged pipe from top to bottom, and valve rod is horizontally through middle ring flange
Center；It is connected on pipeline in flanged pipe pair；Handle is fixedly connected with valve rod.
Upper flange plate, middle ring flange and the lower flange is successively sleeved on flanged pipe from top to bottom, and passes through spiral shell
Bolt is fixed.
When work, fluid media (medium) is passed through in pipeline, rotational handle drives the valve core rotation in flanged pipe by valve rod, real
The adjusting of unlatching, the closing and fluids within pipes flow of existing spool.
It is had the beneficial effect that acquired by the utility model
The utility model is pipeline butterfly-type valve, and spool uses disc type, and unlatching is realized by reciprocating rotating, is closed
With adjust fluid, valve body lighter weight and easy for installation, for valve body without additional attachments in flanged pipe, whole valve body structure is simply tight
It gathers, it is cheap and easy to maintenance；Valve body light weight flow resistance is small, makes valve body opening and closing speed faster；Valve body can realize 90 degree of overturnings,
Keep the adjustable extent of fluids within pipes flow big.The utility model adapts to social innovation development trend, efficiently solves globe valve
Door haves the defects that structure is complicated, opening speed is slow, adjustable extent is small, high production cost, maintenance and replacement difficulty it is big, effectively drop
The operation and maintenance cost of low enterprise, and greatly strengthen valve service performance, furthermore butterfly-type can be widely applied to of valve
In the dust-laden cold wind or hot wind gas pipeline of ventilation, environment-friendly engineering in the industries such as work, building materials, using as adjust fluid media (medium) or
The effect of disconnecting device, is widely used, wide market.
Detailed description of the invention
Fig. 1 is pipeline butterfly-type valve mechanism figure；
In figure: 1, valve rod；2, spool；3, upper flange plate；4, middle ring flange；5, lower flange；6, bolt；7, handle；8,
Flanged pipe；9, pipeline.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, pipeline butterfly valve described in the utility model includes valve body, valve seat, handle 7 and flanged pipe 8, institute
Stating valve body includes valve rod 1 and spool 2, and valve rod 1 passes through 2 groups of spool and is integrally formed, and spool 2 is located in flanged pipe 8；The valve seat packet
Upper flange plate 3, middle ring flange 4 and lower flange 5 are included, upper flange plate 3, middle ring flange 4 and lower flange 5 successively cover from top to bottom
On flanged pipe 8, and it is fixed by bolt 6, and valve rod 1 is horizontally through the center of middle ring flange 4；It is connected in 8 pairs of flanged pipe
On pipeline 9.Handle 7 is fixedly connected with valve rod 1.
When work, fluid media (medium) is passed through in pipeline 9, rotational handle 7 drives 2 turns of spool in flanged pipe 8 by valve rod 1
It is dynamic, the adjusting of fluid flow in the unlatching, closing and pipeline 9 to realize spool 2.
