Pressure-Water Valve Actuator
Pressure-valve actuator water is the most popular type of water valve. This bellows attached to the high pressure side, it is desirable that the cylinder head. This bellows running water valve. As condenser pressure rises, bellows into the water valve contracts. The valve opens any different mechanisms, depending on the specific water valve. Water enters the condenser cooling of the compressed steam. The valve opens, the water circuit is only when water is neededas the pressure rises. It will continue to grow, the flow of water as long as there is a high increase in the pressure from the side.
These valves can be adjusted by means of heavy spring that presses against fur. Valves are set to open in a certain head pressure. Pressure depends on the water temperature and coolant. Some of the pressure-controlled water designs require open the system, remove the valve. Others may be removed without violation of the cooling system.
Water consumption can be modulated (adjusted) with this valve. As the condensing pressure and temperatures increase, the valve opens more.
When the pressure and the temperature drops, water consumption is reduced. Valve person composition hard rubber, Bakelite, or fiber. The seat is usually made of copper or brass. The valves are equipped with either a seal or furs. This is where the water stem goes in the water valve body. The packaging must be adjusted occasionally to keep it from leaking.
These valves, as a rule, do not depend on the pipe for support. However, they have a circuit layout or flange. The inlet and the outlet clearly marked. Valves are usually threaded pipes standard connections. Most is designed so that the pressure of the water as a rule, hold the valve is closed. This valve gear mechanism for adjusting the pressure. Pressure-operated double water valve Fig. 13-145 control the flow in two separate circuits.
