Specific embodiment
Below with reference to embodiment and attached drawing, the present invention is described further.
As shown in Figure 1, including handle 1, valve rod 2, sealing the present embodiment provides a kind of clean type butterfly valve that strainability is strong
Lid 3, upper seal 20, port lid 4, sealing ring 5, valve body 6, spray head 7, injector seals body 8, the second sealing ring 9, block 10, lower valve
Body 11, butterfly plate 12, the first filtering body 15, the second filtering body 14, the second block 16, sphere 17 and spring 18, the setting of butterfly plate 12 exist
Inside valve body 6, sealing cover 3 is arranged outside valve body 6, and the setting of lower valve body 11 is arranged in 6 lower end of valve body, upper seal 20 in valve body
6 upper ends, block 10 are arranged between butterfly plate 12 and lower valve body 11, and valve rod 2 passes through sealing cover 3, upper seal 20, valve body 6, block
10 and butterfly plate 12 be arranged, handle 1 is placed on valve rod 2, and the first filtering body 15 is mounted on 6 front end of valve body, and valve body 6 is filtered with first
