Description
Technical field
The utility model is related to industrial valve manufacture field, more particularly to a kind of new butterfly valve.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in construction, what the switch available for low pressure pipeline medium was controlled
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, a kind of valve of open and close is reached around valve shaft rotation, valve can
For controlling all kinds such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium
The flowing of fluid.It is main on pipeline to play cut-out and throttling action.
In the prior art, butterfly valve only one of which butterfly plate, and the contact surface of butterfly plate and valve seat is larger, if occurring on contact side face
Some seal leakages, the sealing of whole valve just cannot be guaranteed, and the replacement cost of butterfly plate and valve seat is high and waste time and energy,
Schedule delays.
Utility model content
The purpose of this utility model is to provide a kind of new butterfly valve, effectively improves the sealing of valve, extend butterfly valve
Service life.
To achieve the above object, the utility model proposes new butterfly valve, including valve body, butterfly plate, handwheel, transmission mechanism and
Bonnet, it is characterised in that the transmission mechanism includes an active valve rod, a worm screw and two driven valve rods, the active
Valve rod is perpendicular to the valve body, and two driven valve rods are parallel within the both sides of the active valve rod, the worm screw setting
In the bonnet, the worm screw two ends are held with the bonnet side-wall shaft and are connected, and the worm screw is parallel to the valve body, the valve
Lid is connected with the valve flange, the bottom of the active valve rod and the top of two driven valve rods respectively by gear with it is described
Worm engaging, the top of the active valve rod is connected with the handwheel, the bottoms of two driven valve rods respectively with valve body bottom
Butterfly plate described in one is fixed with portion's bearing connection, two driven valve rods, and the butterfly plate is located in the valve body.
Further, in the new butterfly valve, the butterfly plate is with being provided with sealing ring at the valve body contact.
Compared with prior art, the beneficial effects of the utility model are：Two parallel butterflies are set in the valve body of butterfly valve
Plate, and double butterfly plate run-in synchronisms are driven by gear drive, the sealing of butterfly valve is effectively increased, and extend butterfly valve
Service life.
Brief description of the drawings
Fig. 1 is new butterfly valve structure side view in the embodiment of the utility model one；
Fig. 2 is the structure top view of transmission mechanism in the embodiment of the utility model one.
Embodiment

Bar 44, the active valve rod 41 is perpendicular to the valve body 10, and two driven valve rods 42 are parallel within the active valve rod
41 both sides, the worm screw 44 is arranged in the bonnet 50, and the two ends of worm screw 44 are held with the side-wall shaft of bonnet 50 and are connected,
The worm screw 44 is parallel to the valve body 10, and the bonnet 50 is connected with the flange of valve body 10, under the active valve rod 41
Portion and the top of two driven valve rods 42 are engaged by gear 43 with the worm screw 44 respectively, the top of the active valve rod 41 with
The handwheel 30 is connected, and the bottom of two driven valves 42 is connected with the bottom bearing of valve body 10 respectively, two driven valve rods
Butterfly plate 20 described in one are fixed with 42, and the butterfly plate 20 is located in the valve body 10, the butterfly plate 20 and the valve body
10 contact positions are provided with sealing ring (not shown).
To sum up, in the new butterfly valve that the utility model embodiment is provided, set in the valve body of butterfly valve two it is parallel
Butterfly plate, and double butterfly plate run-in synchronisms are driven by gear drive, the sealing of butterfly valve is effectively increased, and extend butterfly valve
Service life.
Preferred embodiment of the present utility model is above are only, any restriction effect is not played to the utility model.
Any person of ordinary skill in the field, in the range of the technical solution of the utility model is not departed from, to the utility model
The technical scheme and technology contents of exposure make the variation such as any type of equivalent substitution or modification, belong to without departing from the utility model
Technical scheme content, still fall within protection domain of the present utility model.
