Abstract
The utility model relates to a double-linkage adjustable ball valve which is composed of two ordinary ball valves, a switch valve, and an adjusting valve. The end port of the switch valve is connected with the inlet of the adjusting valve into a body; the switch valve of the double-linkage adjustable ball valve has the functions of opening and closing; the adjusting valve is used for adjusting flow rate of medium under full open state of the switch valve according to needs. The double-linkage adjustable ball valve solves the problem that the ordinary high temperature resistance ball valves can only be switched but can not be adjusted.
Description
The utility model relates to a kind of valve, particularly a kind of resistant to elevated temperatures ball valve.
Resistant to elevated temperatures ball valve has a wide range of applications in fields such as steam pipeline, chemical industry.Present high temperature resistant ball valve generally is confined to the function of opening and closing.Though also can regulate the rate-of flow that passes through on the pipeline, shortened the working life of ball valve greatly.This mainly is owing to the high temperature media by ball valve makes the seal ring on the ball seat deform, misplace or harden, and is directed at the ball valve sealing decreased performance at last, leakage phenomenon occurs.
The purpose of this utility model is at the problems referred to above, but a kind of not only switch, but also the duplex adjustable ball valve that can regulate are provided.
This duplex adjustable ball valve is by two common ball valves: switch valve and modulating valve are formed, and the outlet end of switch valve and the entrance point of modulating valve are connected as a single entity.In this duplex adjustable ball valve, switch valve plays opening and closing, is in standard-sized sheet or full-shut position during use all the time.Modulating valve is a flow of regulating medium when switch valve is in full-gear as required.In order to improve the sealability of this ball valve, the seal ring on the switch valve spheroid can adopt graphite and ptfe composite to make.
Compared with prior art, this duplex adjustable ball valve is because its switch valve is in standard-sized sheet or full-shut position all the time, and medium is less to the seal ring influence of switch valve during use, so have better seal performance and long working life.In this ball valve, because the sealing of modulating valve is not required substantially, therefore the flow of regulated at will medium as required uses very convenient.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the structural representation of the duplex adjustable ball valve that provides of the utility model.
Among the figure, 1, switch valve; 2, modulating valve; 3, entrance point; 4, outlet end; 5, spheroid; 6, seal ring; 7, valve rod; 8, handle; 9, valve body.
As shown in the figure, this duplex adjustable ball valve is by two common ball valves: switch valve 1 and modulating valve 2 are formed side by side, and the valve body 9 at outlet end 4 places of switch valve 1 is connected as a single entity with the valve body 9 at modulating valve 2 entrance points 3 places.Seal ring 6 on switch valve 1 interior spheroid 5 adopts resistant to elevated temperatures soft sealing structure, promptly makes by graphite and ptfe composite, and the both available soft seal of seal ring 6 in the modulating valve 2, also available hard sealing.The operation of ball valve is to drive spheroid 5 rotations by valve body 9 two outer handles 8 by valve rod 7 to realize.
Claims (2)
