Abstract
The utility model is related to butterfly valve technical fields, more particularly to a kind of board-like three-eccentric-butterfly-valve of bivalve, including identical two butterfly valves of structure are linked together by babinet between the valve body of two butterfly valves, it is equipped with relief valve in the bottom of babinet, Electric Actuator is fitted on two butterfly valves.The present apparatus is simple in structure, is distally carrying out chain by Electric Actuator, can synchronize unlatching, also can individually open.Bleeder valve is housed in body cavity, impurity can be carried out under unilateral open state and released.The function of three valves is replaced by a valve, effectively reduces installation manufacturing cost.
Description
Technical field
The utility model is related to butterfly valve technical field more particularly to a kind of board-like three-eccentric-butterfly-valves of bivalve.
Background technology
One three-eccentric-butterfly-valve is all installed on pipeline at present, needs to increase on pipeline again one three when pipeline overhauls partially
Heart butterfly valve, relatively expends the time in this way, and working efficiency is relatively low.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of board-like three-eccentric-butterfly-valves of bivalve.
The utility model to achieve the above object, using following technical scheme：
A kind of board-like three-eccentric-butterfly-valve of bivalve, it is characterised in that：Including identical two butterfly valves of structure, the valve of two butterfly valves
It is linked together by babinet between body, is equipped with relief valve in the bottom of babinet, Electric Actuator is fitted on two butterfly valves.
Preferably, the butterfly valve includes valve body, lower valve shaft, valve seat, multi-layer sealing ring, valve plate pressing plate, valve plate, upper valve
Axis；The lower valve shaft is mounted on the lower part of the valve body by short sleeve, and the top of lower valve shaft is connect with the lower part of the valve plate,
The multi-layer sealing ring by the valve plate pressing plate be mounted on the valve plate on, the valve seat be mounted on the valve body on and with
Multi-layer sealing ring cooperation, the upper valve shaft are connect by filling body with the valve body top, the upper valve shaft it is upper
Portion is connect with the Electric Actuator, and the Electric Actuator is mounted on by holder on the valve body.
Preferably, the valve body top is equipped with stuffing-box, and the filling body is placed in stuffing-box, the filling body packet
Include Packing seat, filler, filler pressing sleeve and hold-down grid, hold-down grid is bolted with the valve body top, by backing strap,
Filler, filler pressing sleeve are mounted in stuffing-box.
The utility model has the beneficial effects that:Compared with the existing technology, the present apparatus is simple in structure, by Electric Actuator remote
End progress is chain, can synchronize unlatching, also can individually open.Bleeder valve is housed in body cavity, can be carried out under unilateral open state
Impurity is released.The function of three valves is replaced by a valve, effectively reduces installation manufacturing cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram that two butterfly valves are opened simultaneously；
Fig. 3 is the structural schematic diagram that one of butterfly valve opens another butterfly valve closure.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.Such as Fig. 1-Fig. 3 institutes
Show, a kind of board-like three-eccentric-butterfly-valve of bivalve, including identical two butterfly valves of structure, the butterfly valve include valve body 1, lower valve shaft 2, valve
Seat 3, multi-layer sealing ring 4, valve plate pressing plate 5, valve plate 6, upper valve shaft 7；The lower valve shaft is mounted on the valve body by short sleeve
Lower part, the top of lower valve shaft connect with the lower part of the valve plate, and the multi-layer sealing ring is installed by the valve plate pressing plate
On the valve plate, the valve seat is mounted on the valve body and coordinates with the multi-layer sealing ring, and the upper valve shaft passes through
Filling body is connect with the valve body top, and the top of the upper valve shaft is connect with the Electric Actuator, the electronic execution
Device is mounted on by holder 8 on the valve body.The valve body top is equipped with stuffing-box, and the filling body is placed in stuffing-box,
The filling body includes Packing seat 9, filler 10, filler pressing sleeve 11 and hold-down grid 12, hold-down grid on the valve body
Portion is bolted, and backing strap, filler, filler pressing sleeve are mounted in stuffing-box.
Linked together by babinet 13 between the valve body of two butterfly valves, the bottom of babinet be equipped with relief valve 14, two
Electric Actuator 15 is fitted on butterfly valve.The present apparatus is simple in structure, is distally carrying out chain by Electric Actuator, can synchronize open
It opens, also can individually open.Bleeder valve is housed in body cavity, impurity can be carried out under unilateral open state and released.By a valve
Instead of the function of three valves, installation manufacturing cost is effectively reduced.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
