Abstract
The utility model discloses a butterfly valve. The butterfly valve consists of an indicator plate, a manual actuator, a pneumatic actuator, a support, a valve rod, a rotary body piece, a filler, a valve seat, a shaft sleeve and a choke plug, and is characterized in that the valve block is provided with a hard sealing piece and a rectangular non-metal sealing piece for dual sealing, and two spiral slots at the upper end of the valve rod are mutually symmetrically distributed. The butterfly valve has the benefits as follows: when the butterfly valve is opened or closed and before a butterfly plate is rotated, the butterfly plate firstly generates swing displacement and after leaving a sealing surface of a valve body, the butterfly plate rotates, thus eliminating the phenomenon that the valve can not be closed tightly or opened, avoiding damage by abrasion, prolonging service life and simultaneously ensuring the reliability of sealing due to the dual sealing structure of hard and soft pieces.
Description
Technical field
The utility model relates to the valve field in the instrument and meter for automation, is specifically to belong to have running shaft and have a kind of butterfly valve that flow and force disconnect are regulated in the swing rotation, can be widely used in occasions such as chemical industry is inflammable, severe toxicity.
Background technique
Present employed butterfly valve, adopt butterfly plate and valve body to open and close, and the moment that opens and closes is bigger, because the keying number of times is frequent, sealing surface weares and teares easily, thereby cause valve to produce leakage phenomenon, simultaneously, valve body adopts single soft seal or single hard sealing, and sealability is not good, and the restraint of labour condition, make troubles to the user.
Summary of the invention
The purpose of this utility model provides good seal performance, and the butterfly valve seal face opens and closes not easy to wear, and driving torque is little, and operating range is big, opens and closes stuck a kind of butterfly valve not occur.
To achieve these goals, technical solution adopted in the utility model is:
A kind of butterfly valve, by indicator board, manual actuator, pneumatic actuator, support, valve rod, revolve body spare, filler, valve seat, axle sleeve, plug is formed, it is characterized in that valve seat is provided with hard Sealing and the nonmetal Sealing double seal of rectangle, two spiral chutes that are positioned at the valve rod upper end distribute symmetrically, holding down bolt on spiral chute and the support cooperatively interacts, support inserts in the spiral chute, the lower end of valve rod is provided with the passing inclined-plane, valve rod and pneumatic actuator, manually actuator connects by solid of rotation, passes two spring bolts that are provided with on inclined-plane and the butterfly plate and cooperatively interacts.
The beneficial effects of the utility model: the utility model is before butterfly plate rotates when opening or closing, produce a swing displacement earlier, just rotate after leaving valve body sealing surface, eliminate the phenomenon that valve fits badly or do not open, overcome the damage of wearing and tearing, increase working life, simultaneously because the hardware and software double sealing structure is guaranteed the reliability that seals.

Embodiment
Please refer to its implementation process of description of drawings:
A kind of butterfly valve, by indicator board, manual actuator, pneumatic actuator, support, valve rod, revolve body spare, filler, valve seat, axle sleeve, plug is formed, it is characterized in that valve seat 3 is provided with hard Sealing 4 and nonmetal Sealing 5 double seals of rectangle, two spiral chutes that are positioned at valve rod 9 upper ends distribute symmetrically, holding down bolt 12 on spiral chute and the support 11 cooperatively interacts, support 11 inserts in the spiral chute, the lower end of valve rod 9 is provided with the passing inclined-plane, valve rod 9 and pneumatic actuator 15, manually actuator 14 connects by solid of rotation 16, also comprise adapter 1 in addition, 2 and link 10, two spring bolts 7 passing setting on inclined-plane and the butterfly plate 6 cooperatively interact.Even described spiral chute takes the lead in leaving sealing surface with the butterfly plate 6 that cooperates of holding down bolt 12, controlling butterfly plate 0-90 degree corner aperture again regulates, the passing inclined-plane that valve rod 9 is divided into goes at butterfly plate 6 can produce a lateral thrust when closing, push butterfly plate 6 to valve body sealing surface by spring bolt 7, on sealing surface, produce a bigger sealing load, seal tighter, when the passing inclined-plane of valve rod 9 lower ends compressing spring bolt 7, butterfly plate 6 is laterally moved, butterfly plate 6 rotates after breaking away from sealing surface earlier, shows set flow or unlatching by aperture indication 13, it is little to open and close moment like this, stuck phenomenon can not take place.
The beneficial effects of the utility model: the utility model is before butterfly plate rotates when opening or closing, produce a swing displacement earlier, just rotate after leaving valve body sealing surface, eliminate the phenomenon that valve fits badly or do not open, overcome the damage of wearing and tearing, increase working life, simultaneously because the hardware and software double sealing structure is guaranteed the reliability that seals.
Those skilled in the art's simple replacement and replacing all are within the protection domain of this patent in related domain.
