Embodiment Construction

[0011] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings:

[0012] The overflow control valve (2) includes a water inlet connection flange (11), an upper limit orifice plate (12), a fixed sealing plate (13), a rubber sealing ring (14), a movable sealing plate (15), and an upper fixed flange (16), the lower fixing flange (17), the buoy (18), the lower limit orifice (19), the guide rod (20), the upper valve body (21) and the lower valve body (22), the buoy (18) and the The movable sealing plates (15) are welded together, and are respectively fixed with guide rods (20). The upper limit orifice plate (12) and the lower limit orifice plate (19) are perforated plates to facilitate the passage of water, and the overflow control valve (2) is welded to the top of the negative pressure tank (1) through the lower valve body (22). , and then connected with the upper valve body (21) through the fixed f...

Abstract

Self-priming frequency converter water supply equipment comprises a negative pressure tank provided with an overflow control valve, a water pump, a check valve, a butterfly valve, an outfall sewer, a pressure sensor, a frequency converter control cabinet, a check valve by-pass and a water suction pipe; water is supplied for the negative pressure tank through the check valve by means of the outfall sewer; the water level of the negative pressure tank is controlled by the overflow control valve arranged on the negative pressure tank; the water in the negative pressure tank can be prevented from being overflowed and can be guided reliably so that a small circle is prevented from being formed to waste the energy; and a water pump sucks water through the negative pressure tank under the combined control of the frequency converter control cabinet and the pressure sensor so that the full-automatic frequency converter constant-pressure water supply is realized.

Description

technical field [0001] The invention relates to a frequency conversion water supply equipment, in particular to a frequency conversion water supply equipment applied to water supply to buildings under the condition that the water pump is self-priming. Background technique [0002] At present, the working state of the water pump usually has two types: self-priming and self-priming. In order to ensure reliable water supply, self-priming is usually required. However, for some special places, the location of the pool is low, and the water pump cannot meet the requirements. Self-priming work mode, only self-priming work mode can be used, which requires priming and water diversion before the pump is started. The methods of perfusion and diversion usually include manual operation, vacuum pump diversion and traditional negative pressure tank diversion. Manual irrigation and water diversion requires a bottom valve to be installed on the water pump suction pipe, which increases the r...
