Abstract
The utility model discloses a multifunctional butterfly type ball valve. The ball valve is formed by a valve seat, a ball body, a sliding block and the like in a valve body. A butterfly valve formed by the ball body, a butterfly plate in the valve body, a valve rod and the like has the functions of adjusting quantity of fluid and sealing a closed circuit at the same time. The butterfly valve is operated and controlled by a valve rod connection sleeve through the valve rod. The multifunctional butterfly type ball valve has the function of bi-directional breakover of the fluid, reduces use times of a valve in a pipeline and achieves the effect of being multifunctional and is convenient to operate and control.
Description
Technical field
The utility model relates to a kind of multi-functional butterfly ball valve, and is a kind of multi-functional, and two-way function has the adjusting of fluid flow and the ball valve of closed circuit sealing function concurrently.
Background technique
When general ball valve was done the modulating valve use, Flow characteristics was relatively poor, and just began to open or close end of a period when spheroid is in
The time, fluid pressure difference is large, and flow velocity is high, and valve seat is easy to be washed out, and therefore, uses often in actual use a butterfly valve
Use with a cut-off valve (such as gate valve, stop valve or ball valve) series connection, with the adjusting of bearing respectively fluid flow and closed circuit
Seal two kinds of functions.
Summary of the invention
The purpose of this utility model is: a kind of multi-functional butterfly ball valve simple in structure, of high quality and at a reasonable price is provided, has adjusting and two kinds of functions of closed circuit sealing of fluid flow concurrently.The utility model is achieved in that a kind of multi-functional butterfly ball valve, and it is comprised of bottom, bottom valve bar, middle valve body, left and right sides valve body, spheroid, valve seat, valve rod, butterfly plate, slide block, Stuffing box, Gland, positioning block and valve rod connecting sleeve etc.
In the utility model, described bottom and middle valve body, left and right sides valve body connect to form valve body by fastening piece, valve seat is housed in the valve body, described valve seat supporting spheroid, described spheroid endoporus is equipped with butterfly plate, described butterfly plate and valve rod are affixed, and there is the supporting of bottom valve bar described valve rod lower end surface, and described valve rod connecting sleeve underpart is enclosed within the valve rod upper end.Described Stuffing box is fixed tightly on the middle valve body, and described Gland is fixed tightly on the Stuffing box, and described positioning block is affixed by a locating stud and Gland.
In the utility model, described valve base sealing surface build-up welding STL, hardness HRC38-42 makes valve seat and ball seal good.Between described valve seat and the left and right sides valve body spring is arranged, described spheroid and left and right sides valve body consist of ball valve.
In the utility model, described butterfly plate cylindrical cooperates with described spheroid endoporus is movable, and described butterfly plate and spheroid consist of fly valve, control the fly valve flow by the valve rod connecting sleeve by valve rod.
In the utility model, the filler between described Stuffing box and the described Gland is graphite.
The beneficial effects of the utility model make the control of dish formula ball valve convenient operation, reduce the valve consumption, reach the effect of multi-purpose valve.
