Product Description

Product Description
The marine valve is a device used to control the pressure, flow and flow direction of the fluid in the ship's pipeline to meet the environmental conditions of the ship. The valve is the control device of the fluid pipeline. Its basic function is to connect or cut off the flow of the medium in the pipeline, change the flow of the medium, change the flow direction of the medium, adjust the pressure and flow of the medium, and protect the normal operation of the equipment in the pipeline.
1. According to the channel direction of the globe valve, it is divided into:
1) Straight-through globe valve
2) DC globe valve: In the DC or Y-shaped globe valve, the flow channel of the valve body forms a diagonal line with the main channel, so that the degree of damage to the flow state is smaller than that of the conventional globe valve, so the pressure loss through the valve is also corresponding. 's small.
3) Angle globe valve: In the angle globe valve, the fluid only needs to change direction once, so that the pressure drop through the valve is smaller than that of the conventional structure globe valve.
4) Plunger globe valve: This form of globe valve is a variant of the conventional globe valve. In this valve, the disc and seat are designed based on the plunger principle. The valve disc is polished so that the plunger is connected with the valve stem, and the sealing is realized by two elastic sealing rings sleeved on the plunger. The two elastomeric seals are separated by a collar and compress the seal around the plunger by the load applied to the bonnet by the bonnet nut. Elastomeric seals are replaceable and can be made of a variety of materials, the valve is mainly used for "open" or "closed", but is available with special forms of plungers or special collars and can also be used to regulate flow .
2. According to the position of the thread on the stem of the globe valve, it can be divided into:
1) Upper threaded stem globe valve: The thread of the globe valve stem is outside the valve body. The advantage is that the valve stem is not eroded by the medium and is easy to lubricate. This structure is relatively common.
2) Lower threaded stem globe valve: The thread of the globe valve stem is in the valve body. The stem thread of this structure is in direct contact with the medium, which is easily corroded and cannot be lubricated. This structure is used in places with small diameters and low temperatures.
The principle of the marine anti-wave valve is actually a one-way check. Generally, there is a tongue plate with a spring inside, which is closed under normal conditions, and the forward fluid can open the tongue plate. Open the valve, the reverse flow cannot open the tongue plate. Due to the limitation of the valve seat, there are also requirements during installation. First, it cannot be installed in reverse. Secondly, if the design requires vertical installation, it cannot be installed horizontally. Otherwise, it will be inconvenient to open or not to close tightly due to the weight of the inner tongue plate.
The anti-surge valve is used to discharge sewage or waste water, and can automatically close and prevent the backside valve of the outboard water.
