Abstract
The utility model relates to a reverse braking nozzle device of an impulse turbine. The device comprises a rotary wheel which is mounted in the middle part of a shell and provided with a water bucket, a working spray nozzle, a spray needle and a water spraying bent pipe communicated with the working nozzle, wherein the working spray nozzle is horizontally mounted at the lower part of the shell and the jet flow of the working spray nozzle is aligned with the concave surface of the water bucket. A reverse spray nozzle is horizontally mounted on the upper part of the shell; the jet flow of the reverse spray nozzle is aligned with a convex surface of the water bucket; the water inlet end of the reverse spray nozzle is communicated with a gate valve through a horizontal pipe and a small bent pipe; and the gate valve is communicated with the water spraying bent pipe through a vertical pipe. The gate valve is an electric gate valve, a hand gate valve or an electric/hand dual-purpose gate valve. In order to stop the machine, the spray needle is closed, the water flow jetted to the concave surface of the water bucket of the rotary wheel is cut off, the gate valve is opened, and the pressure water of the water spraying bent pipe is jetted to the convex surface of the water bucket of the rotary wheel through the reverse spray nozzle so as to form resistance opposite to the rotation direction of the rotary wheel, thus stopping the turbine in a braking mode. The device has a simple structure and ensures that the material is saved, the cost is reduced and the operation and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of impulse water wheel thermomechanical components, particularly a kind of impulse turbine plugging spray nozzle device.
Background technique
At present; impulse turbine is shut down braking and is adopted and drive oil brake or pressurized air by pressure oil and promote pneumatic brake and embrace that brake disc brakes; these braking devices need be provided with a big brake disc; and outfit pressure oil-source or pressure gas source; complex structure has increased manufacture cost and user cost.
Summary of the invention
The purpose of this utility model has provided a kind of impulse turbine plugging spray nozzle device that utilizes the hydraulic brake runner.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of impulse turbine plugging spray nozzle device, comprise and be installed in the runner that the casing middle part is provided with bucket, level is installed in the casing bottom, the main jet of jet aligning bucket concave surface and nozzle needle and the water spray bend pipe that is communicated with main jet.The contrainjector level is installed in casing top, and the contrainjector jet is aimed at the convex surface of bucket, and the feed-water end of contrainjector is communicated with gate valve by transverse tube and little bend pipe, and gate valve is communicated with the water spray bend pipe by vertical tube.Described gate valve is electric gate valve, hand sluice valve or electric-hand driven two-purpose gate valve.
The beneficial effects of the utility model are: when preparing to shut down, nozzle needle is closed in the action of water turbine nozzle mechanism, cuts off the current of directive runner bucket concave surface; When rotational speed of water turbine reduce to rated speed 50% the time, open gate valve, the press water of water spray bend pipe, forms the resistance opposite with the runner sense of rotation, and makes the water turbine brake application stoping through the convex surface of contrainjector directive runner bucket by little bend pipe and transverse tube.This apparatus structure is simple, and economical with materials reduces cost, convenient operating maintenance.
