Description

Double-flow-speed long-handle water cap

Technical Field

The utility model relates to a long handle water cap of double flow rate belongs to water treatment facilities technical field.

Background

The water cap is applied to a mechanical filter of water treatment equipment. When filtering water, the treated water flows out from top to bottom through the filter material layer and the water cap. When the filter material layer needs to be cleaned, the water cap is switched to a back washing state, back washing water flows in from bottom to top and is sprayed out through the water cap to wash the filter material layer, and at the moment, a high water flow velocity is needed to achieve a good washing effect.

However, in the prior art, in the back-flushing state, the back-flushing water passes through the water cap from bottom to top, the flow valve core is jacked up by the back-flushing water, floats upwards to the bottom of the through-flow valve cup along the connecting rod, blocks the flow hole at the bottom of the through-flow valve cup, and cannot obtain a larger flow area, so that the requirement of the water cap on the flow speed in the back-flushing state cannot be met. In addition, during back flushing, the compressed air has too large inlet amount, which can cause the water cap to vibrate and loosen, thus causing material leakage.

SUMMERY OF THE UTILITY MODEL

In order to make the water cap obtain bigger flow area when the back flush, improve the vibrations problem simultaneously, the utility model provides a long handle water cap of double flow rate.

The utility model provides a pair of long handle water cap of double flow rate adopts following technical scheme:

a double-flow-speed long-handle water cap comprises a flow guide pipe and a flow guide valve core; the flow valve core is arranged at the top end of the flow guide pipe and can float up and down, and a protruding structure is arranged at the upper end of the flow valve core; in the prior art, during back washing, the flow valve core is jacked up by back washing water, is far away from the top end of the flow guide pipe, floats upwards to the bottom of the flow valve cup along the connecting rod, blocks a circulation hole at the bottom of the flow valve cup, reduces the circulation area and reduces the flow rate of the back washing water. And through the protruding structure arranged at the upper end of the flow valve core, only the protruding structure on the upper surface of the flow valve core is contacted with the cup bottom during back flushing, so that the opening of the flow hole at the bottom of the flow valve cup can be kept, a larger flow area is obtained, and a larger flow speed is obtained.

In order to ensure that the flow valve core is not deflected when being jacked up by back washing water, the double-flow-rate long-handle water cap preferably has 3 protruding structures which are uniformly distributed.

Preferably, the surface of the flow guide pipe is provided with threads, and a gasket and double nuts matched with the threads are arranged on the surface of the flow guide pipe. When using with the cooperation of precoat perforated plate, thread width and perforated plate thickness adaptation, the honeycomb duct passes and stretches to the precoat perforated plate under the rubber circle, fastens on the precoat perforated plate through gasket and two nuts. During back washing, because the inlet amount of compressed air is too large, when only one nut is used, the water cap vibrates excessively, and the conditions of loosening and material leakage are easy to occur. And the double nuts and the gaskets are used for fastening, so that the water cap is effectively prevented from loosening, and the cost is saved.

Preferably, the lower end of the flow guide pipe is provided with a dilatation groove and a dilatation hole. By the mode, the inlet amount of compressed air and backwashing water during backwashing is increased, and the flow rate of the backwashing water is increased.

Preferably, the top end of the flow guide pipe is provided with an opening, the water cap cover plate, the trapezoid sieve pipe with the ribs, the water cap base and the flow guide pipe are connected through a welding process. Thereby avoiding the trouble in installation and ensuring that the whole structure of the water cap is firmer and more stable.

The cup mouth of the through-flow valve cup is inversely arranged at the middle shaft of the water cap base, the cup wall extends to two ends of the water cap base from top to bottom and is connected by a welding process, and a plurality of through holes are arranged on the cup wall and the cup bottom and are reserved with connecting holes. All parts are connected through a welding process, so that the internal structure of the water cap is more stable.

To sum up, the utility model discloses following useful technological effect has:

1. the different requirements of the water cap on the flow velocity under two working states are met, and a larger flow velocity is obtained during back flushing;

2. the purpose of preventing looseness is achieved, material leakage is avoided, and cost is saved;

3. the structure is stable, and the installation is convenient;

4. during back flushing, the input of back flushing water and compressed air is increased, and the back flushing force is increased.
