Details

The ASV-1 series safety relief valve is mainly used for various pressure vessels, instrument devices, and pressure reducing valve outlets to prevent accidents caused by abnormal pressure rise.

The steam pressure reducing valve regulates the flow rate of the medium by controlling the opening and closing of the valve body, thereby reducing the pressure of the medium.At the same time, adjust the opening of the opening and closing parts through the pressure behind the valve to maintain the pressure behind the valve at a certain level. Within this range, when the inlet pressure constantly changes, maintain the outlet pressure within the set range to protect subsequent household and production appliances.

Steam pressure reducing valves are generally installed horizontally and controlled by the pressure behind the valve. When the pressure sensor detects an increase in the valve pressure indicator, the valve opening of the pressure reducing valve decreases; When the pressure of the pressure reducing valve is detected, the valve opening of the pressure reducing valve increases to meet the control requirements.

The pressure reducing ratio of the steam pressure reducing valve must be higher than the system value; Even at a certain flow rate, it should be able to respond to positive or negative control signals.These valves should be selected based on the useful control range, which is 20% to 80% of the flow rate.Usually, it is proportional or has an equal ratio. These types of valves have the flow characteristics and flow range required for proportional control.

Classification of steam pressure reducing valves

According to structure, it can be divided into diaphragm type, spring diaphragm type, piston type, lever type, and bellows type; According to the number of valve seats, single seat and double seat; According to the position of the valve disc, it can be divided into positive action type and reaction type.

There are many types of steam pressure reducing valves, including pilot piston pressure reducing valves, membrane pressure reducing valves, bellow pressure reducing valves, proportional pressure reducing valves, self operated pressure reducing valves, direct acting piston pressure reducing valves, back pressure control valves, etc. They are suitable for different working media.

Steam pressure reducing valve is an intelligent valve that utilizes the energy of the medium to regulate and control pipeline pressure.Used for industrial water supply systems such as domestic water supply and fire water supply.The outlet pressure of the main valve can be adjusted through the pressure reducing pilot valve of the control valve.The outlet pressure does not change due to changes in inlet pressure and flow rate. The outlet pressure is safely and reliably maintained at the set value, and can be adjusted as needed to achieve pressure reduction. This valve has accurate pressure reduction, stable performance, safety and reliability, convenient installation and adjustment, and long service life.

The steam pressure reducing valve mainly controls the fixed outlet pressure of the main valve.The outlet pressure of the main valve does not change due to changes in inlet pressure, and its outlet pressure does not change due to changes in the outlet flow rate of the main valve.It has the function of improving system operating conditions and potential water-saving. According to statistics, its water-saving effect is about 30%. Suitable for industrial water supply, fire water supply, and domestic water pipe network systems.Steam pressure reducing valves are widely used in high-rise buildings, areas with high water pressure in urban water supply networks, mines, and other occasions to ensure that each water intake point in the water supply system receives appropriate domestic water pressure and flow.

The Plumbing must be flushed and cleaned before installing the steam pressure reducing valve. To prevent welding slag, oxide skin, and other impurities from entering the valve and affecting its normal operation.The steam pressure reducing valve should be installed in a place that is convenient for operation and maintenance, and must be installed vertically on a horizontal pipeline. Attention should be paid to ensuring that the flow direction of the medium in the pipeline is consistent with the direction indicated by the arrow on the valve body, and it should not be installed backwards.
