Threaded Modular Valve (Threaded Modular Valve) is a common hydraulic control element that combines different modules and components to achieve different hydraulic control functions. Before we can properly assemble a threaded combination cartridge valve, we need to understand its components and the assembly sequence.
Threaded combination cartridge valves are usually composed of the following important parts:
Cartridge valve body: The cartridge valve body is the main part of the threaded combination cartridge valve, usually cast or machined. Threaded holes and sealing grooves are provided inside the cartridge valve body for mounting each module of the cartridge valve.
Cartridge valve module: Cartridge valve module is usually a small control valve used to achieve different control functions of the hydraulic system. Cartridge valve modules can be one-way valves, flow control valves, pressure control valves, etc.
O-type sealing ring: O-type sealing ring is usually used to realize the seal between the modules of the threaded combination cartridge valve to ensure the sealing performance of the system.
Thread: The thread is used to connect the cartridge valve module to the cartridge body, usually with some standard thread specification, such as NPT, BSPP, etc.
The steps to properly assemble a threaded combination cartridge valve are as follows:
Preparation: Before starting assembly, it is first necessary to check that the individual components and modules are complete, free of damage, and clean.
Check the seal ring: Check whether the O-ring seal is intact to avoid leakage caused by aging or wear of the seal ring.
Assemble cartridge valve module: Select the appropriate cartridge valve module according to the desired hydraulic control function and assemble it correctly according to its operating instructions.
Install O-ring: Before installing the cartridge valve module, apply lubricant to the threaded holes and sealing slots of the cartridge valve module, and then install the O-ring to ensure the correct installation of the seal ring.
Assemble the cartridge valve module and cartridge body: Connect the cartridge valve module to the cartridge body, pay attention to the corresponding relationship between the direction and the thread, gently rotate and tighten by hand.
Thread fastening: Use appropriate tools to properly tighten the thread to avoid thread damage or leakage caused by too tight or too loose.
Cleaning and lubrication: After the assembly is completed, clean the assembled threaded combination cartridge valve, and apply an appropriate amount of lubricant to the thread to ensure the flexibility and tightness of the valve.
To sum up, the correct assembly of the threaded combination cartridge valve requires attention to select the appropriate cartridge valve module, pay attention to lubrication and correct installation when installing the O-ring, and properly tighten the thread. At the same time, it is also very important to keep the threaded combination cartridge valve clean and lubricated. The correct assembly of the threaded combination cartridge valve can ensure the normal operation and reliability of the hydraulic system.
