A kind of butterfly valve with coarse filtration function of this utility model, compared with prior art has advantages below：
First, this have in the butterfly valve of coarse filtration function by by described butterfly plate be designed as annular round frame and with described ring
The grid that shape round frame is connected, makes described butterfly plate when being rotated or the anglec of rotation is less, that is, when the circulation of described butterfly valve
When amount is less, described grid has good coarse filtration ability.Now, described grid can be by the bulky grain float in current
It is blocked at described butterfly valve, because described conveyance conduit is fixedly connected by described ring flange with described butterfly valve, thus periodically clear
The dismounting during float that reason is gathered at described grid, to install described butterfly valve all very convenient, this design be also be accurately positioned outstanding
The accumulation of float is assembled position and is provided convenience.
Second, this has valve rod described in the butterfly valve of coarse filtration function and described butterfly plate, described bushing and described valve body
It is fixedly connected by grafting.This be mainly designed in order to make described valve rod and described butterfly plate, described bushing and described valve body it
Between assembling, dismounting simpler, thus improving the overhaul efficiency of described butterfly valve.
3rd, this has bushing described in the butterfly valve of coarse filtration function is wear resistant elastic material.This design not only gives institute
State the good anti-wear performance of bushing, beneficial to the service life extending described bushing；Also as described bushing has certain elasticity
And make its sealing better.

Specific embodiment
In order to be better understood from this utility model, with reference to specific embodiments and the drawings, this utility model is entered with traveling one
The description of step.
As shown in Figure 1-2, a kind of butterfly valve with coarse filtration function, including valve body 3, the both ends of the surface of described valve body 3 are fixed
It is connected with the ring flange 2 for being arranged on described valve body 3 in fluid-transporting tubing, in described valve body 3, be cased with abrasionproof bushing
5, it is provided with butterfly plate 4 in described bushing 5.It is removably connected with valve rod 1 in described butterfly plate 4, described bushing 5 and described valve body 3,
Described butterfly plate 4, described bushing 5 and described valve body 3 are fixed as an entirety by described valve rod 1.Described butterfly plate 4 can be with described
Valve rod 1 is rotated for rotary shaft, and the anglec of rotation of described butterfly plate 4 is 0-90 °, and described butterfly plate 4 includes annular round frame, described ring
It is fixed with a grid with coarse filtration function in shape round frame.
In this utility model, by described butterfly plate 4 being designed as annular round frame and being connected with described annular round frame
Grid, makes described butterfly plate 4 when being rotated or the anglec of rotation is less, when that is, the circulation of described butterfly valve is less, described lattice
Grid have good coarse filtration ability.Now, the bulky grain float in current can be blocked in described butterfly valve by described grid
Place, because described conveyance conduit is fixedly connected by described ring flange 2 with described butterfly valve, so periodic cleaning is gathered in described lattice
Dismounting during float at grid, install that described butterfly valve is all very convenient, this design is also that the accumulation being accurately positioned float is assembled
