Overview

• What are the characteristics of three way stopcock?

  1. A three way stopcock has two valve cores and a valve seat structure similar to that of a double seat valve, but in a three way stopcock, when the flow area between one valve core and the valve seat increases, the flow between the other valve core and the valve seat The area is reduced. In a double-seat valve, the flow area between the two valve cores and the valve seat increases or decreases at the same time.

  2. The air opening and closing of the three way stopcock can only be achieved by selecting the positive and negative effects of the actuator. In the double-seat valve, the air opening and closing can be directly achieved by reversing the valve body or valve core and the valve seat. to realise.

  3. When the three-way stopcock is used in a control system that requires fluids for proportioning, since it can replace an air-on control valve and an air-off control valve at the same time, it can reduce installation costs and reduce installation space.

  4. The three way stopcock can also be used in bypass control places. For example, one fluid needs to pass through the heat exchanger to exchange heat, and the other fluid does not need to pass through the heat exchanger to exchange heat. When the three way stopcock is installed in front of the heat exchanger, the split flow is used Three way stopcock, when the three way stopcock is installed behind the heat exchanger, a combined three way stopcock is used. Since the liquid flowing in the three way stopcock installed in front of the heat exchanger has the same temperature, the leakage is small. The liquid flowing in the three way stopcock installed after the heat exchanger has different temperatures. The degree of expansion is different, so the leakage is larger. Generally, the temperature difference between the two liquids should not exceed 150 degrees.
