Water stopping and discharging control structure for aspergillum

Abstract

The water stop and out-flow control device for a water sprinkler is set on the base followed with the sprinkling control set driven reciprocal water inlet set which has a tube with several through holes with several nozzles and seal going through the stop water area, both sides of the tube having several control hole connected to the inside of the tube controlling the control bar pivot, a water inlet hole sticking to the piston having an active space with the sealed water stop area, being able to move up and down under the charge against the current, opposite to the nozzle along with the movement of the control bar to control the water flow.

Description

technical field [0001] The invention relates to a water stop and water outlet control structure of a sprinkler, which uses the piston of the control rod to climb up with the pressure of the water flow and touch the water stop area of ​​the seal to reduce the contact area and friction coefficient. The control rod is more labor-saving in operation, and at high water pressure, the piston will be more tightly attached to the water stop area of ​​the seal under the impact of strong water flow, so as to prevent the water flow from the nozzle or the nozzle at high water pressure. The absence of perforated seepage enables the control rod to maintain a better leak-proof purpose regardless of high or low water pressure. Background technique [0002] China Taiwan Patent No. 1241157 and the No. 6736340B1 sprinkler of U.S. Patent No. 6736340B1, although a control rod with a neck cooperates with a water outlet and a seal of a saddle seat to control the water outlet when the water is out ...

Problems solved by technology

[0002] China Taiwan Patent No. 1241157 and the No. 6736340B1 sprinkler of U.S. Patent No. 6736340B1, although a control rod with a neck cooperates with a water outlet and a seal of a saddle seat to control the water outlet when the water is out , but in operation, often because the shaft of the control rod must be completely fitted on the saddle seat covered with the seal, so that the contact area between the shaft and the saddle seat is increased and the friction coefficient is relatively increased, so that the control rod is easy to push. It is more difficult, and because the shaft and the saddle are attached in an arc shape, the friction resistance is relatively large. Therefore, when the water pressure is high, the strong water flow will hit the peripheral surface of the shaft of the control rod against the saddle. The inner surface seeps into the water outlet through the gap between the shaft and the saddle, which makes the control rod not effective in preventing leakage and water under high water pressure.
