Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of pneumatic flange-type three butterfly valve partially.
Background technique
Butterfly valve is in pipeline, use comparatively common a kind of parts realizing pipeline break-make and flow control, and sealing effect is structurally comparatively reliable.Especially in the environment of circulation being applied in gas and liquid medium, sealing better effects if is required, and tradition use butterfly valve not only torque is large when in use, operation is comparatively bothered, and the sealability of butterfly valve is poor, in the process used very much, cause very large waste, thus cost also improves greatly.
Model utility content
For the deficiency of butterfly valve in prior art, the utility model provides a kind of sealability better butterfly valve inclined to simple pneumatic flange-type three more convenient to operate.
To achieve these goals, the technological scheme that the utility model is intended adopting is:
A kind of pneumatic flange-type three butterfly valve partially, comprise valve rod, valve body, dish plate and pneumatic actuator, valve rod one end is connected with valve body, the valve rod the other end is connected with pneumatic actuator, valve rod between valve body and pneumatic actuator is provided with support and Gland from top to bottom, Gland compresses filler and Packing seat, pedestal upper end portion is by bolt and key and pneumatic actuator fixing and locking, valve rod top in valve body is provided with axle sleeve two, stem lower portion in valve body is provided with axle sleeve one, in valve body, in the middle of valve rod, a side is provided with dish plate, dish plate external application dish plate gland compresses, dish plate is fixedly connected with by screw one with dish plate gland, by pin fixing and locking between dish plate and valve rod, support below Gland is provided with cotter pin, swing bolt and bearing pin.
Be lined with packing ring one between described bolt and pneumatic actuator, described packing ring one quantity is four, makes to be connected more firm with pneumatic actuator by packing ring one.
Described support is connected with packing ring two by screw two with Gland, and described screw two and packing ring two correspondence are provided with four, is convenient to better by support and Gland locking.
Be provided with seal ring between described dish plate and valve rod, be convenient to dish plate to be connected with valve rod more tight, make sealability better.
Described Gland is used nut fixing and locking, be conducive to Gland and compress filler and Packing seat.
The beneficial effects of the utility model: the utility model is by being provided with support and Gland between valve body and pneumatic actuator, make to connect between butterfly valve more firm, decrease the incidence rate of fault, and the utility model is tightr between structures, make sealability better, more be applicable to the medium circulations such as steam, air, water and oil product, decrease waste.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model side view.
Embodiment
As depicted in figs. 1 and 2, a kind of pneumatic flange-type three butterfly valve partially, comprise valve rod 2, valve body 3, dish plate 7 and pneumatic actuator 19, valve rod 2 one end is connected with valve body 3, valve rod 2 the other end is connected with pneumatic actuator 91, valve rod 2 between valve body 3 and pneumatic actuator 19 is provided with support 15 and Gland 21 from top to bottom, Gland 21 compresses filler 22 and Packing seat 23, support 15 upper end portion is by bolt 17 and key 16 and pneumatic actuator 19 fixing and locking, valve rod 2 top in valve body 3 is provided with axle sleeve 29, valve rod 2 bottom in valve body 3 is provided with axle sleeve 1, in valve body 3, in the middle of valve rod 2, a side is provided with dish plate 7, dish plate 7 external application dish plate gland 5 compresses, dish plate 7 is fixedly connected with by screw 1 with dish plate gland 5, by pin 6 fixing and locking between dish plate 7 and valve rod 2, support 15 below Gland 21 is provided with cotter pin 10, swing bolt 11 and bearing pin 12, packing ring 1 is lined with between described bolt 17 and pneumatic actuator 19, described packing ring 1 quantity is four, make to be connected more firm by packing ring 1 with pneumatic actuator 19, described support 15 is connected with packing ring 2 13 by screw 2 14 with Gland 21, described screw 2 14 and packing ring 2 13 correspondence are provided with four, be convenient to better support 15 and Gland 21 be locked, seal ring 4 is provided with between described dish plate 7 and valve rod 2, dish plate 7 is convenient to be connected tightr with valve rod 2, make sealability better, with nut 20 fixing and locking on described Gland 21, be conducive to Gland 21 and compress filler 22 and Packing seat 23.
Working principle of the present utility model is when needs are closed, and first pneumatic actuator 19 connects external electromagnetic valve, thus band ovable valve stem 2 moves, and then realizes the closedown of dish plate member; When needs are opened time, first the utility model is exitted, then by realizing to pneumatic actuator 19 inflation the breakdown action that valve rod 2 drives dish plate member.
The beneficial effects of the utility model: the utility model is by being provided with support and Gland between valve body and pneumatic actuator, make to connect between butterfly valve more firm, decrease the incidence rate of fault, and the utility model is tightr between structures, make sealability better, more be applicable to the medium circulations such as steam, air, water and oil product, decrease waste.
