Abstract
The utility model discloses a fixed turbine-drive ball valve. The fixed turbine-drive ball valve comprises a gearbox, a valve rod, a valve body, a locating pin, a hand wheel and a valve element, wherein the valve element is a cylindrical large-caliber valve element, the locating pin penetrates through the lower end of the valve body and is rotationally connected with the lower end of the valve element, the upper end of the valve element is fixedly connected with the lower end of the valve rod, the upper end of the valve rod is connected with a rotating shaft at one end of the gearbox, and a rotating shaft at the other end of the gearbox is connected with the hand wheel. Compared with the prior art, the fixed turbine-drive ball valve has the advantages of being simple in structure and low in cost; particularly, the cylindrical large-caliber valve element is adopted for the fixed turbine-drive ball valve, so that the flow resistance coefficient of the valve is small; by the adoption of transmission conducted through the gearbox, resistance can be reduced, time and labor are saved, and popularization and use value is obtained.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of worm gear drive fixing ball valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.The good valve of work can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.And valve mechanism complexity of the prior art, laborsaving is not difficult to promote.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem a kind of worm gear drive fixing ball valve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises gear-box, valve rod, valve body, locating stud, handwheel and spool, described spool is cylindrical heavy caliber spool, described locating stud is rotationally connected through the lower end of described valve body and the lower end of described spool, the upper end of described spool is fixedly connected with the lower end of described valve rod, the upper end of described valve rod is connected with one end rotating shaft of described gear-box, the other end rotating shaft of described gear-box is connected with described handwheel, between described spool and described valve body, be provided with seal ring, the bore of described spool equates with the pipe diameter of described valve body, the upper end of described spool is parellel, between the center, upper end of described spool and the lower end of described valve rod, be threaded connection, the lower end of described spool is parellel, the center of described spool lower end is provided with circular groove, described locating stud is placed in described circular groove, in described gear-box, it is reducing gear, between described valve rod and described valve body, be provided with seal ring, between described locating stud and described valve body, be bolted, between described gear-box and described valve body, be provided with connection bracket.
The beneficial effects of the utility model are:
The utility model is a kind of worm gear drive fixing ball valve, compared with prior art, the utlity model has advantage simple in structure, with low cost, especially the utility model adopts cylindrical bigbore spool, make the flow resistance coefficient of valve little, adopt gearbox drive can alleviate resistance, time saving and energy saving, there is the value of promoting the use of.
