Bronze valves, compared to other models, have a longer service life even working with high temperatures and pressures.
Bronze originally refers to copper-tin alloy, but the industry is used to call copper alloys containing aluminum, silicon, lead, beryllium, manganese, etc. also bronze, so bronze actually includes tin bronze, aluminum bronze, aluminum bronze, beryllium bronze, silicon Bronze, lead bronze, etc. Bronze is also divided into two categories: press-worked bronze and cast bronze.
C95800 nickel-aluminum-bronze Valve:
C95800 nickel-aluminum-bronze diaphragm valve can be divided into a two-way nickel-aluminum-bronze diaphragm valve, three-way nickel-aluminum-bronze diaphragm valve, and seawater-resistant diaphragm valve according to the circulation mode.
Nickel Aluminum Bronze Diaphragm Valves are used in scientific research, electronics, machinery, metallurgy, petroleum, chemical industry, energy, biology, refrigeration, food, and other fields. The sealing principle of the nickel-aluminum bronze diaphragm valve is to press down the diaphragm or diaphragm assembly and the channel of the weir-type lining valve body or the straight-through lining valve body by the downward movement of the operating mechanism, so as to achieve sealing.
C83600 Tin Bronze Casting Valves ( ZCuSn5Pb5Zn5 Cu-Sn bronze valves )
Tin Bronze Valves, Cu-Sn Bronze Valves, Shipbuilding Bronze 20k Globe Valves
Owning the Corrosion-resistance behavior in corrosion of seawater, the seawater bronze valves, C83600 Tin Bronze Valves are called Navy Bronze Valves, and are widely distributed with the various types in warships and are mostly in the corrosive environment, and settled the difficulties of maintenance of the seawater pipeline.
The Tin Bronze Valve alloys are famous for their good corrosion resistance, high strength, better wear resistance, and lower friction coefficient compared to the common steel. They can afford shock and impact loading, but with reduced surface speeds which makes them the better choice for high strength bushing and bearing components applications.
Types and Features of Marine Bronze Valves
1. Overview of bronze gate valves
When the valve is opened, when the lift height of the gate is equal to 1:1 times the diameter of the valve, the fluid channel is completely unobstructed, but this position cannot be monitored during operation.
In order to take into account the lock-up phenomenon caused by temperature changes, it is usually opened to the top position, and then back to 1/2-1 turn, as the position of the fully open valve. Therefore, the fully open position of the copper valve is determined according to the position (ie stroke) of the gate.
The navy bronze gate valves have two sealing surfaces. The two sealing surfaces of the most commonly used gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2°52" when the medium temperature is not high.
The bronze wedge gate the plate can be made into a whole called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its manufacturability and make up for the deviation of the angle of the sealing surface during processing. This kind of gate is called an elastic gate.
1. According to the configuration of the sealing surface, it can be divided into wedge gate valve and parallel gate valve; wedge gate valve can be divided into the single gate, double gate, and elastic gate; parallel gate valve can be divided into single gate Ram and Double Ram.
2. According to the thread position of the bronze valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. When closed, the sealing surface can be sealed only by medium pressure.
3. The gate of the seawater bronze gate valve moves linearly with the valve stem, which is called a lift-rod gate valve (also called an open-rod gate valve). Usually, there are trapezoidal threads on the lift rod; for some bronze gate valves, the valve stem nut is set on the gate plate, and the rotation of the handwheel drives the valve stem to rotate, and the gate plate is lifted. This kind of valve is called a rotary stem gate valve or a dark stem gate valve.
Bronze globe valve refers to a valve in which the closing member (disc) moves along the centerline of the valve seat. According to this moving form of the valve disc, the change of the valve seat port is proportional to the valve disc stroke.
Because the valve stem of this type of valve has a relatively short opening or closing stroke and has a very reliable shut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow regulation. Therefore, this type of valve is ideal for shut-off or regulation as well as throttling.
The bronze check valve is a multi-purpose valve with both the function of a globe valve and a check valve. During use, it has the following characteristics:
1. It can be used as an active check valve to prevent the steam from flowing back into the boiler from the main steam heater.
2. It is helpful to block the boiler and prevent the pressure of the water heater from flowing back to the boiler.
3. After sealing, it helps to bring boiler steam into the piping system. If there are multiple boilers connected to the main steam water heater, a stop check valve should be installed on the pipeline between each boiler and the water heater.
This valve arrangement should be such that the pressure in the boiler sits below the valve disc. The upright valve can be used on horizontal lines or straight lines with upward flow. Angle valves can be used on fluid lines running horizontally up or down.
Bronze ball valves
The aluminum bronze ball valve adopts the top-loading structure, and the main alloy elements are nickel, iron, and manganese; in actual use, in order to meet different needs, a certain amount of manganese, iron, nickel, zinc, and other elements are often added to the aluminum bronze to Change alloy properties; It has excellent corrosion resistance and is an important material for ship propellers and undERWater fasteners, and has been widely used in seawater desalination and other projects.
Bronze butterfly valves
Marine Bronze Valves immersed pneumatic butterfly valve is the execution unit in the pneumatic unit combination instrument. It comes from the signal of the regulating instrument to change the cut-off and circulation of the medium. The product has a large operating force, a novel valve body design, flow Small resistance, large rated flow coefficient, and excellent sealing performance.
The aluminum bronze butterfly valve is one of the commonly used valve varieties in industrial pipelines. The valve is small in size, less material, light in weight, and more economical than other valves with larger diameters. The actuator can be opened and closed quickly by rotating 90°, and the operation is simple.
At the same time, the aluminum bronze butterfly valve has good fluid control characteristics. When the valve is in the open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body.
Hence, the pressure generated by the aluminum bronze butterfly valve is very small, and when the opening degree is between about 15° to 70°, it can be sensitive to the flow control. With the large-diameter flow regulation, the valve has greater advantages. However, this valve is not suitable for process medium with particles and high temperatures.
