Abstract
The utility model discloses a kind of worm-gear type butterfly valve, including valve seat, valve body, valve plate, valve rod, o-ring, manual heads.Inserting valve rod in the valve seat, valve plate is set with the valve rod, the valve plate coordinates with valve seat, valve body is connected on the valve seat, setting-in o-ring in the valve body, counterpart is set on the valve body, and the counterpart interpolation harness there are the manual heads of worm screw, and the valve rod sequentially passes through valve seat, valve plate and valve body from down to up；And stretch into counterpart, worm gear is fixed in the valve rod upper surface, and the worm gear coordinates with valve rod.The beneficial effects of the utility model are that simple structure, operation facility is practical.
Description
Technical field
The utility model is related to pipeline valve, particularly a kind of worm-gear type butterfly valve.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve of simple structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation, and 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.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Rotated around the axis of its own, so as to reach the purpose for opening and closing or adjusting.
At present directly firmly rotary manual head can be only achieved the effect of regulation to many butterfly valves using artificial, once add operation person
Labour.
Utility model content
The purpose of this utility model is, in order to solve the above problems, to devise a kind of worm-gear type butterfly valve.
Realize that above-mentioned purpose the technical solution of the utility model is, a kind of worm-gear type butterfly valve, including valve seat, in the valve seat
Inserting valve rod, is set with tab (s) on the valve rod, the tab (s) coordinates with valve seat, valve body is connected on the valve seat, in the valve body
Setting-in o-ring, sets counterpart on the valve body, the counterpart interpolation harness has the manual heads of worm screw, and the valve rod is under
To above sequentially passing through valve seat and valve body；And stretch into counterpart, worm gear is fixed in the valve rod upper surface, and the worm gear is matched somebody with somebody with worm screw
Close.
The longitudinal section of the valve seat is circle.
The longitudinal section of the tab (s) is circle.
The size of the tab (s) and valve seat, shape and structure are identical.
The manual heads are embedded in bearing with counterpart through part.
The worm-gear type butterfly valve made using the technical solution of the utility model, by the cooperation of worm gear and worm screw, realizes butterfly
The closing of piece, mitigates the labour of operator significantly.
Brief description of the drawings
Fig. 1 is the structural representation of worm-gear type butterfly valve described in the utility model；
Fig. 2 is the front view of worm-gear type butterfly valve described in the utility model；
In figure, 1, valve seat；2nd, valve rod；3rd, tab (s)；4th, valve body；5th, o-ring；6th, counterpart；7th, manual heads；8th, worm gear.
Specific embodiment
The utility model is specifically described below in conjunction with the accompanying drawings, as shown in Figure 1-2, a kind of worm-gear type butterfly valve, including
Inserting valve rod (2) in valve seat (1), the valve seat (1), is set with tab (s) (3), the tab (s) (3) and valve seat on the valve rod (2)
(1) coordinate, setting-in o-ring (5) in valve body (4), the valve body (4) is connected on the valve seat (1), set on the valve body (4)
Counterpart (6), the counterpart (6) interpolation harness has the manual heads (7) of worm screw, and the valve rod (2) sequentially passes through from down to up
Valve seat (1) and valve body (4)；And stretch into counterpart (6), worm gear (8) is fixed in valve rod (2) upper surface, the worm gear (8) with
Worm screw coordinates；The longitudinal section of the valve seat (1) is circle；The longitudinal section of the tab (s) (3) is circle；The tab (s) (3) and valve
The size of seat (1), shape are identical with structure；The manual heads (7) are embedded in bearing with counterpart (6) through part.
The characteristics of the present embodiment is that inserting valve rod in valve seat is set with tab (s) on valve rod, tab (s) coordinates with valve seat, valve seat
Setting-in o-ring, sets counterpart in upper connection valve body, valve body on valve body, and counterpart interpolation harness has the manual heads of worm screw, valve rod
Valve seat and valve body are sequentially passed through from down to up；And stretch into counterpart, worm gear is fixed in valve rod upper surface, and worm gear coordinates with worm screw,
By the cooperation of worm gear and worm screw, the closing of tab (s) is realized, the labour of operator is mitigated significantly.
In the present embodiment, by the manual heads of rotary worm so that worm screw rotates, and then cause that worm gear turns with worm screw
Dynamic, band ovable valve stem is rotated so that the tab (s) being sleeved on valve rod is rotated so that the present apparatus is opened or closed, control air,
Water, steam, various Korrosionsmediums, to water, the flowing of the chemically all kinds fluid such as medium, play cut-out or throttling
Effect, by above-mentioned operation principle, solves the problems, such as to be mentioned in background technology, time saving and energy saving, saves labour, operation letter
It is single, it is practical and convenient.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel's some that to be made to some of which part variations embody principle of the present utility model, belong to the utility model
Protection domain within.
