Abstract
The utility model relates to a combination structure of a multifunctional range quick-opening valve lever and a ball nut, which comprises the valve lever, a rolling ball sliding device and the nut in rotational sliding fit with the valve lever, wherein, the valve lever or the nut is fixedly connected a valve body; a corresponding nut or a corresponding valve lever is fixedly connected with a valve; the valve lever (the nut) is rotated to drive the corresponding nut (or the corresponding valve lever) to move, thereby driving the valve to be matched with the valve body to open or close the valve. A rolling ball chute is arranged on the surface of the valve lever and is in the shape of a threaded line; a bolt hole of the nut is a through-hole; a rolling ball hole is formed on the nut and perpendicular to the axis of the bolt hole; and the rolling ball device is arranged in the rolling ball hole and is in fit with the rolling ball chute of the valve lever. The valve of the combination structure of the valve lever and the nut can greatly increase the operating stroke of the valve lever, reduce the friction force between the valve lever and the nut, facilitate quick and convenient opening and closing, and ensure working stability and reliability.
Description
Technical field
The utility model relates to a kind of valve fittings, refers to that especially a kind of valve that is used for is with the valve rod that improves this valve and the multi-functional range quick-opening valve bar and the ball nut composite structure of nut speed of related movement.
Background technique
Valve mechanism in the past, because valve and valve rod adopt triangle or trapezoidal worm structure to carry out transmission, this structure not only resistance is big, start relatively effort, and because screw thread travel is less, valve rod needs a lot of circles of relative rotation just can reach required stroke with nut engaged during the folding valve, the speed of folding is slow, in order to increase folding speed, often be that the mode by electronic startup realizes apace, though increased the speed of folding like this, but still greatly reduce the reliability and stability of valve working, and increased the manufacture cost of equipment, improved the requirement of valve, dwindled using scope working environment.
The model utility content
Technical purpose of the present utility model is in order to overcome above-mentioned defective, provides a kind of variable speed, valve rod travel is big, folding speed is fast and labour-saving multi-functional range quick-opening valve bar and ball nut composite structure.
For realizing above technical purpose, multi-functional range quick-opening valve bar of the present utility model and ball nut composite structure comprise valve rod and with this valve rod rotational slide nut engaged, valve rod wherein or nut are fixedlyed connected with valve body, corresponding nut or valve rod are fixedlyed connected with valve, drive corresponding nut (or valve rod) motion by rotary valve rod (or ball nut), thereby drive valve and cooperate to come this valve of switch with valve body, this quick opening valve bar and ball nut composite structure also include the ball sliding device, this stem surface is provided with the ball spout of the screw thread wire that cooperates with ball, the bolt hole of this nut is a through hole, nut is provided with the ball hole with this bolt hole axis normal, and the ball sliding device is located in the ball hole and with the valve rod ball spout and is cooperated.
Described ball hole runs through nut outer surface and bolt hole, be provided with internal thread in this ball hole, described ball sliding device comprises that ball and surface are provided with externally threaded circle ring column, the inboard end of this circle ring column is provided with spherical ball groove and is used for ccontaining and the ball that is slidingly connected, the circle ring column and the ball hole of this ball sliding device are mutually permanently connected by screw thread, ball cooperates with the ball spout of valve rod, and ball spout bar number is at least 2 usually, and general ball spout is made as 3.
Beneficial effect: the valve that adopts multi-functional range quick-opening valve bar of the present utility model and ball nut composite structure, can increase the working stroke of valve rod greatly, reduce the frictional force size between valve rod and the nut, thereby not only folding is quick more and convenient, thereby, reduce the cost of valve and improved the reliability of equipment not by electronic control also folding valve apace.
Relevant detailed content of the present utility model and technology are described as follows with regard to conjunction with figs. now.
Description of drawings
Fig. 1, be the partial sectional view that the utility model valve rod and nut cooperate;
Fig. 2, be the A-A sectional view of Fig. 1.
Embodiment
Please refer to illustrated in figures 1 and 2, a kind of specific embodiment for the utility model multi-functional range quick-opening valve bar and ball nut composite structure, for realizing above-mentioned purpose, this embodiment's multi-functional range quick-opening valve bar and ball nut composite structure comprise valve rod 1 and with this valve rod 1 rotational slide nut engaged 2, wherein valve rod 1 or nut 2 are fixedlyed connected with valve body, corresponding nut 2 or valve rod 1 are fixedlyed connected with valve, drive corresponding nut 2 (or valve rod 1) motion by rotary valve rod 1 (or nut 2), thereby drive valve and cooperate to come this valve of switch with valve body, this quick opening valve bar and nut combinations knot also include the ball sliding device, this valve rod 1 surface is provided with the ball spout 10 of the screw thread wire that cooperates with ball 6, the bolt hole 22 of this nut 2 is a through hole, nut 2 is provided with the ball hole 20 with this bolt hole 22 axis normal, and the ball sliding device is located in the ball hole 20 and with valve rod 1 ball spout 10 and is cooperated.
The ball hole 20 of present embodiment runs through nut outer surface and bolt hole, be provided with internal thread in this ball hole 20, described ball sliding device comprises that ball 6 and surface are provided with externally threaded circle ring column 3, these circle ring column 3 inboard ends are provided with spherical ball groove and are used for ccontaining and are slidingly connected ball 6, the circle ring column 3 of this ball sliding device and ball hole 20 are mutually permanently connected by screw thread, ball 6 cooperates with the ball spout 10 of valve rod 1, ball 6 cooperates with the ball spout 10 of valve rod 1, and ball spout 10 of the present utility model is 3.
In summary it can be seen, this embodiment's of the utility model the multi-functional range quick-opening valve bar and the valve of ball nut composite structure, can increase the working stroke of valve rod 1 greatly, reduce the frictional force size between valve rod 1 and the nut 2, thereby not only folding is quick more and convenient, thereby, reduce the cost of valve and improved the reliability of equipment not by electronic control also folding valve apace.
