Abstract
The utility model relates to a pressure sensing device of secondary pressurizing water supply equipment, which comprises a voltage stabilizing expansion drum, a remote transmitting pressure meter, a tee joint, an elbow and a connecting pipe. The pressure sensing device is characterized in that the voltage stabilizing expansion drum is installed on a main water outlet pipe of secondary pressurizing water supply equipment, and the tee joint is arranged on a pipeline from the main water outlet pipe to the voltage stabilizing expansion drum. One path of the tee joint is connected with the voltage stabilizing expansion drum, and the other path of the tee joint is connected with the remote transmitting pressure meter. Regardless of one water pump works or two water pumps work, pressure water entering the voltage stabilizing expansion drum and the remote transmitting pressure meter is restricted and regulated through the voltage stabilizing expansion drum, and the flowrate variation of the remote transmitting pressure meter is small, so the fluctuation of the pressure meter is greatly reduced. By the automatic control function of variable frequency speed control, the outputted pressure value can be constant in 0.01Mpa and achieves the national standard. Compared with the like product, the pressure sensing device has the characteristics of simple control system, reliability, economy and convenience for installation.
Description
Technical field
The utility model relates to a kind of pressure sensor device of secondary booster water supply facilities.
Background technology
In the device product that utilizes city planting ductwork overbottom pressure secondary booster, nothing more than forming by water inlet pipe, adjusting water pot, booster water pump, negative pressure arrester, connecting line, gate valve, flap valve, electro connecting pressure gauge, pressure capsule system, variable frequency control cabinet, outlet pipe etc.General device producer control output constant pressure is only to adorn a teletransmission pressure meter on outfall sewer, connect the variable frequency control cabinet, set the output pressure value, the output pressure value must not exceed ± 0.01Mpa when moving by the GB regulation, but such simple mechanism is the force value instability often, it is low when time thes be high, its reason is the user with discharge hour, pump work only, flow is little, and the user is with discharge when big, two pump works, flow is big, though switch board has the frequency converter timing converting operation, only do not regulate the flow that enters teletransmission pressure meter pipeline at any time by a force pipe, flow velocity, pressure oscillation is bigger, the constant pressure of output influences normal water well beyond 0.01Mpa.
Summary of the invention
The purpose of this utility model just provides a kind of pressure meter that can significantly reduce and fluctuates, and controls the output pressure value automatically, the pressure sensor device of the reliable secondary booster water supply facilities of economical operation.
The pressure sensor device of secondary booster water supply facilities of the present utility model, comprise voltage stabilizing expansion drum, teletransmission pressure meter, threeway, elbow and tube connector, be characterized in that the voltage stabilizing expansion drum is contained on the outfall sewer of secondary booster water supply facilities, pipeline from outfall sewer to the voltage stabilizing expansion drum is provided with threeway, threeway one tunnel is connected with the voltage stabilizing expansion drum, and another road of threeway links to each other with the teletransmission pressure meter.
The pressure sensor device of secondary booster water supply facilities of the present utility model, because the voltage stabilizing expansion drum is contained on the outfall sewer, water in the outfall sewer, one the tunnel enters the voltage stabilizing expansion drum, another road enters the teletransmission pressure meter of the threeway other end, like this no matter be a pump working or two pump workings, enter the manometric press water of voltage stabilizing expansion drum and teletransmission and be subjected to the restriction and the adjusting of voltage stabilizing expansion drum, make the manometric changes in flow rate of teletransmission little, therefore manometric fluctuation significantly reduces, add the automatic control action of frequency control, the output pressure value can be constant in 0.01Mpa, reaches the GB requirement, compares with like product, it is simple to have control system, reliable, economical, characteristics easily are installed.
