Description

A kind of soft sealing butterfly valve of bi-direction zero-leakage
Technical field
The utility model relates to butterfly valve field, refers more particularly to a kind of soft sealing butterfly valve of bi-direction zero-leakage.
Background technique
At present, industrial valves door type is various, can be widely used in the industries such as chemical industry, food, water, electricity, mainly play Flow-rate adjustment and the cut-off effect of flowing medium.
Butterfly valve refers to that valve plate rotates a kind of valve reaching open and close around valve rod, pipeline mainly plays a part cut off and throttling.The flexible soft seal of butterfly valve and metal hard-sealing two kinds of seal form, the valve of metal hard-sealing is generally long than the life of valve of soft seal, the working environment that energy Applicable temperature is higher, but sealability is good not as the valve of soft seal.
Model utility content
The soft sealing butterfly valve of the bi-direction zero-leakage that the purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provides a kind of structure simple, easy to operate, practical.
The utility model realizes in the following way:
A soft sealing butterfly valve for bi-direction zero-leakage, is characterized in that: comprise valve body 6, butterfly plate 7, and described valve body 6 is provided with stream chamber 61; The two ends up and down of described butterfly plate 7 are connected to upper valve rod 14 and lower valve rod 8; Described butterfly plate 7 is positioned at stream chamber 61; The other end of described upper valve rod 14 is connected by the upper end of axle sleeve 5 with valve body 6; The bottom of described lower valve rod 8 is connected to the lower end of valve body 6 by splitting snap ring 9; Described upper valve rod 14 and lower valve rod 8 rotatable relative to valve body 6; The top of described valve body 6 is provided with support 2; Described support 2 is connected with worm gear pair 1; The upper end portion of described upper valve rod 14 is connected with worm gear pair 1; Described worm gear pair 1 is connected with handle 15; The outer wall of described butterfly plate 7 is connected with butterfly plate sealer 12 by trim ring 13; When butterfly plate 7 is closed condition with stream chamber 61, butterfly plate sealer 12 connects with the inwall in stream chamber 61; During action, rotatable handle 15, handle 15 drives worm gear pair 1 to work, and worm gear pair 1 drives upper valve rod 14 to rotate, and then drives butterfly plate 7 to rotate the open and close realizing stream chamber 61.
Described upper valve rod 14 is arranged with seal ring 4 and Gland 3, described Gland 3 is positioned at the top of seal ring 4.
The bottom of described lower valve rod 8 is provided with the bonnet 11 be connected on valve body 6; Joint between described bonnet 11 and valve body 6 is provided with lower seal 10.
The beneficial effects of the utility model are: structure is simple, and easy to operate, long service life, sealability are reliable.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
Embodiment
Now by reference to the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1, a kind of soft sealing butterfly valve of bi-direction zero-leakage, comprises valve body 6, butterfly plate 7, and valve body 6 is provided with stream chamber 61; The two ends up and down of butterfly plate 7 are connected to upper valve rod 14 and lower valve rod 8; Butterfly plate 7 is positioned at stream chamber 61; The other end of upper valve rod 14 is connected by the upper end of axle sleeve 5 with valve body 6; The bottom of lower valve rod 8 is connected to the lower end of valve body 6 by splitting snap ring 9; Upper valve rod 14 and lower valve rod 8 rotatable relative to valve body 6; The top of valve body 6 is provided with support 2; Support 2 is connected with worm gear pair 1; The upper end portion of upper valve rod 14 is connected with worm gear pair 1; Worm gear pair 1 is connected with handle 15; The outer wall of butterfly plate 7 is connected with butterfly plate sealer 12 by trim ring 13; When butterfly plate 7 is closed condition with stream chamber 61, butterfly plate sealer 12 connects with the inwall in stream chamber 61; During action, rotatable handle 15, handle 15 drives worm gear pair 1 to work, and worm gear pair 1 drives upper valve rod 14 to rotate, and then drives butterfly plate 7 to rotate the open and close realizing stream chamber 61.
The utility model upper valve rod 14 is arranged with seal ring 4 and Gland 3, described Gland 3 is positioned at the top of seal ring 4, for the sealing of upper valve rod 14.
The bottom of the utility model lower valve rod 8 is provided with the bonnet 11 be connected on valve body 6; Joint between described bonnet 11 and valve body 6 is provided with lower seal 10, for the sealing of lower valve rod 8.
The utility model is when butterfly plate 7 is closed condition with stream chamber 61, and butterfly plate sealer 12 connects with the inwall in stream chamber 61; During work, during rotatable handle 15, handle 15 drives worm gear pair 1 to work, and worm gear pair 1 drives upper valve rod 14 to rotate, and then drives butterfly plate 7 to rotate the open and close realizing stream chamber 61.
