Embodiment Construction

[0030] like figure 1 The shown water inlet device of the stacked water supply pump station has a water inlet main pipe 1 behind the water supply pipe network, a water pressure gauge 2 is installed on the water inlet main pipe 1, and behind the water inlet main pipe 1 is a parallel normally open pipe 6 and a side Through pipe 9, a solenoid valve 7 for controlling its on-off is installed on the normally open pipe 6, and a flow control valve 10 is installed on the bypass pipe 9; in addition, there is a control unit 4 and a steady flow compensator 11, and the normally open pipe 6 and the bypass pipe 9 respectively have an outlet communicated with the steady flow compensator 11, and the steady flow compensator 11 is communicated with the user water pipe 12;

[0031] The water pressure gauge 2 is connected with the control unit 4 through the signal line 3, and can transmit the water pressure signal; can control their on-off state.

[0032] The diameter of the bypass pipe 9 is 1 / 2-...

Abstract

The invention discloses a water inlet device of a pressure-superposed water supply pump station. A main water inlet pipe is arranged behind a water supply network, and a water manometer for measuring input water pressure or a thermometer is mounted on the main water inlet pipe. A normally-open pipe and a bypass pipe which are connected in parallel are arranged behind the main water inlet pipe. The caliper of the bypass pipe is 1 / 2-1 time that of the normally-open pipe. An electromagnetic valve for controlling the normally-open pipe to be opened or closed is arranged on the normally-open pipe. A flow control valve for controlling the water flow of the bypass pipe is mounted on the bypass pipe. In addition, a control unit and a flow stabilizing compensator are arranged, the normally-open pipe and the bypass pipe are provided with outlets respectively, and the outlets are communicated with a user water pipe after being communicated with the flow stabilizing compensator. The water manometer is connected with the control unit through a signal line, and the control unit is connected with the electromagnetic valve, the flow control valve and a starting component of the flow stabilizing compensator through control lines. The flow and network pressure can be reasonably controlled under the condition of small and large pipe network pressure and too low temperature.

Description

technical field [0001] The invention relates to a water inlet control device for tap water. Background technique [0002] The existing stacked water supply pump station is usually in a normally open state by using an ordinary butterfly valve to control the on-off at the connection with the municipal pipe network. During the peak water consumption period, the water intake of the stacked water supply pumping station is relatively large, which may easily cause the pressure of the water supply network around the stacked water supply pumping station to drop sharply and affect the water supply pressure of the surrounding residents. In extreme cases, a vacuum negative pressure may be formed inside the pipe network, affecting the normal water supply, or even destroying the pipe network, causing great harm. [0003] The utility model with the patent application number of 2010202098088 relates to a water inlet device, in particular to a water inlet device for a washing machine. The ...
