摘要： The present invention relates to a method of controlling pressure maintenance equipment for a cooling and heating system. More particularly, the present invention relates to a method of operating and controlling, under optimum conditions, pressure maintenance equipment with multiple sensors so as to check for irregularities in the sensors which measure the same physical parameter. In the present invention, measurement values of two or more sensors are used to detect whether an abnormality has occurred in any sensor. If a sensor is determined to be abnormal, a measurement value of the abnormal sensor is excluded when determining a reference control value. Thereby, the pressure can be precisely and reliably controlled in response to actual conditions of the system.

摘要： The present invention relates to a water piping system, and more particularly, to a water piping system configured to reduce slam and water hammer of a check valve through delay of backflow of fluid by ejecting water stored in a pressure tank to a fluid forward direction at a high pressure when a pump in the water pipe is suddenly stopped, and through inducement of complete closure of the check valve by reducing a pressure applied to the check valve.

摘要： Disclosed herein is a method of controlling a water level of a pressure tank of a piping system. The piping system includes the pressure tank, a level transmitter, a first level switch disposed on a low-level-alarm line, a second level switch disposed between the low-level-alarm line and a lower limit line of an optimal level range, a third level switch disposed between a high-level-alarm line and an upper limit line of the optimal level range, and a fourth level switch disposed on a high-level-alarm line. The method includes receiving a level measurement value from the level transmitter; receiving and checking ON/OFF signals of the level switches; comparing the level measurement value with the ON/OFF signals; determining whether an abnormality has occurred in the level transmitter, and determining whether to raise or lower the water level; and supplying gas to the pressure tank or exhausting gas therefrom.

摘要： The present invention relates generally to a parallel cylinder-type check valve and, more particularly, to a parallel cylinder-type check valve in which two shock-absorbing dampers are connected in parallel to each other so as to absorb shock when a valve is closed, wherein the length of a rocker arm connected to any one shock-absorbing damper is adjusted to be longer according to the principle of a lever in order to provide a sufficient shock-absorbing effect. Also, the present invention relates to a parallel cylinder-type check valve, which is rapidly closed at a high speed at the time of the initial closing of the valve and is slowly closed at a low speed at the later closing of the valve by means of the parallel cylinder, thereby preventing noise and vibration, as well as preventing water hammer.

摘要： Disclosed herein is a method of controlling the water level of a pressure tank of a piping system. The piping system includes a pressure tank, level sensors, a gas supply device, a supply valve and an exhaust valve. The method includes: measuring the water level; calculating absolute values of difference values between water level measurement values measured by the level sensors, thus obtaining measurement deviation values; comparing the measurement deviation values with a preset deviation value; determining whether an abnormality has occurred in each level sensor; outputting the mean of the measurements of the level sensors, while excluding the measurement of an abnormal level sensor(s), as a reference water-level-control value; and comparing the reference water-level-control value with a preset reference water level value, and determining whether to raise or lower the water level, and supplying gas into the pressure tank or exhausting gas therefrom.
