Description
Technical field
The utility model relates to a kind of hydroturbine water intake ball valve seal ring position indicating device.
Background technique
Hydroturbine water intake ball valve is applicable to water conservancy aqueduct, pumping plant imports and exports pipeline and water power plant intake pipe, and the Trimmed sums as current is opened.Whether the seal ring position indicating device of hydroturbine water intake ball valve, show the position of turbine seal ring in water turbine valve body lead ring, be used to indicate turbine seal and put in place, coordinates terminal proximity switch on operating board, show the position at seal ring place.Indicating device's shifting axle of prior art is connected with adopting screw thread spacer shell between mobile axial filament, processing difficulties, installs inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of convenience to process for deficiency existing in above-mentioned prior art just, is convenient to the hydroturbine water intake ball valve seal ring position indicating device of installation.
The purpose of this utility model realizes by following technique measures:
The mode that hydroturbine water intake ball valve seal ring position indicating device of the present utility model comprises crossing water intake ball valve flange is arranged on the guide sleeve one in flange body, the guide sleeve two in lead ring body is arranged in the mode of crossing water intake ball valve lead ring, and the mobile axial filament to be threaded with seal ring, and described guide sleeve one, guide sleeve two and mobile axial filament are arranged with coaxial line, in described guide sleeve two, shifting axle is installed, described mobile axial filament epitaxial end extends in guide sleeve two, and contacted with the rear end of shifting axle by the mode of structure that steel ball is nested, in described guide sleeve one, in the mobile mode coordinated, indicating arm is installed, indicating arm is coated with spring, match with the land end face being arranged on indicating arm mid-rear portion in one end of spring, the other end of spring be arranged on guide sleeve one before the swivel nut of extending end contact, described indicating arm rear end extends in guide sleeve two, and contact with the rear end of shifting axle, before indicating arm, extending end is provided with collision block, proximity switch is respectively arranged with in the front and back of collision block, described proximity switch is combined with swivel nut by support.
Sealed by O-ring seals respectively between guide sleeve two described in the utility model and water intake ball valve lead ring, shifting axle.
Working principle of the present utility model and beneficial effect as follows:
When seal ring forward end moves, the active force that mobile axial filament promotes shifting axle, indicating arm overcomes spring simultaneously forward end moves, and collision block forward end proximity switch is close; When seal ring moves to the back-end, mobile axial filament, shifting axle and indicating arm move under the elastic force effect of spring simultaneously to the back-end, collision block to the back-end proximity switch is close, carry out the physical location of indicating sealing ring movement in water intake ball valve lead ring with the relative position of collision block, coordinate terminal proximity switch by the position display of seal ring on operating board.
Because the utility model changes the mode adopting screw thread spacer shell to be connected between shifting axle of the prior art with mobile axial filament, and connect shifting axle and mobile axial filament by the mode that steel ball is nested, for machining and installation provide conveniently.In addition adopt spring to ensure indicating arm, shifting axle and the axial displacement each other of mobile axial filament, improve the accurate location of axial displacement each other.
