What Is A Hand Valve?

 What Is A Hand Valve?


Hand Valve is a valve that requires manual intervention to achieve on-off control. It can change the flow direction or size of the fluid in the pipeline, and has the functions of diversion, cut-off, regulation, throttling, check, shunt or overflow relief. It is an important fluid control element.



The working principle of Hand Valves is usually to operate the valve opening and closing by mechanical means such as rotation or lever. When the valve is open, fluid can flow through the valve; When the valve is closed, the fluid is prevented from flowing. According to the needs of specific applications, Hand Valves can be operated in a variety of ways, such as hand wheels, handles, levers, sprockets, etc.

There are many kinds of Hand Valves, which can be divided into ball valves, plug valves, butterfly valves, hand wheel valves, etc. Each valve has its own unique characteristics and applications, such as ball valves for liquid and gas pipeline switch control, plug valves for low and medium pressure liquid and gas pipeline switch control, butterfly valves for low and medium pressure liquid and gas pipeline control.

Marine Hand Valves are usually installed in the ship's piping system to control the flow and shutdown of liquids. According to the needs of the specific application, the Hand Valve can be installed at the inlet and outlet of the pipeline, the outlet of the pump, and the oil tank.

When choosing to purchase a Marine Hand Valve, it is necessary to consider factors such as its applicability, reliability and economy. Specifically, factors such as the working pressure of the Hand Valve, the size of the interface, and the type of media need to be considered. At the same time, it is also necessary to consider the sealing performance, corrosion resistance and safety performance of the manual valve.

When installing Marine Hand Valves, it is necessary to follow the relevant specifications and requirements to ensure that the Hand Valves can work normally and extend their service life. At the same time, it is also necessary to check and maintain the Hand Valve regularly to discover and solve potential problems in time to ensure its safe and reliable operation.

What is a stern tube?

图片
  What is a stern tube? A  stern tube  is a tubular structure in a ship  shaft  used to support and protect the stern shaft. The task of the stern tube device is to support the stern shaft or propeller shaft and allow it to reliably vent out of the ship, while preventing a large amount of outboard water from leaking into the ship and oil leakage. The stern tube  is generally welded directly on the hull structure in the form of cast steel parts, and the bearings are pressed forward and back after processing or using the flexible pouring type of finished products, and then the propeller shaft is installed in the stern shaft tube. The operation and load bearing of the propeller shaft are borne by the stern shaft tube and its bearing. Stern tube is an important part of Marine propulsion system, its manufacturing process and material quality directly affect the performance and safety of the ship. Therefore, there are very high requirements for the manufacture an...

What Is Stern Shaft Covering Sleeve?

图片
  What Is Stern Shaft Covering Sleeve? The stern shaft covering sleeve  is a device that protects the stern shaft of a ship, usually installed at the tail of the ship, covering the stern  shaft . Its main function is to prevent the tail shaft from being corroded and worn by water and other substances, thus extending the service life of the tail shaft. The stern shaft covering sleeve  is usually made of a metal material, such as cast iron or cast steel, but can also be made of a wear-resistant, corrosion-resistant synthetic material. The inside of the stern shaft covering sleeve is usually filled with lubricating oil or preservatives to reduce the friction and wear of the stern shaft. At the same time, in order to better fix the cladding sleeve, fasteners such as bolts are usually used to fix it to the hull. The use of the covered sleeve of the stern shaft can effectively reduce the maintenance and replacement frequency of the stern shaft and improve the operating eff...

Cycloid Reducer Features

  Cycloid Reducer Features Cycloid reducer  has the following characteristics: Compact structure and small size:  due to the use of planetary transmission principle, the input shaft and output shaft are on the same axis line, so that the model can be as small as possible. ​ High transmission efficiency, low noise:  cycloidal needle tooth meshing multi-tooth contact, the contact stress is smaller than the straight tooth cylindrical gear, so the  bearing  life is longer when used. In addition, the tooth type is circular arc, which has less friction, less heat, high transmission efficiency and low noise than the point contact of the straight teeth. Simple maintenance:  cycloidal pinwheel reducer in the application can be configured within 40 degrees of any transmission Angle, for more than 40 degrees of transmission choose bipolar  transmission box . Long service life:  Due to the design of oil bath lubrication and seal cover design, the oil poo...
