Description
Product Overview
The valve core of the control valve is assembled inside the electromagnetic valve of the electronic fuel injector, receiving electronic control electromagnetic signals to achieve rapid up and down movement, controlling the pressure relief and sealing of the high-pressure fuel inside the fuel injector, and precisely controlling the opening and closing times and the fuel injection volume of the fuel injector. Under long-term conditions of thousands of bar of high-pressure fuel flushing, impurities of diesel particles wear, and continuous high-temperature vibration of the engine compartment, scratches occur on the sealing section of the rod body, and the contact surface of the base is worn. This will lead to fuel leakage, drift of the rail pressure, and disorder in the injection timing. The equipment will experience power jerks, multiple starts are required to start, imbalance in single-cylinder operation, and excessive black smoke in exhaust emissions. This product has standardized processing for the total length of the rod body, the dimensions of the stepped sections, and the outer diameter of the base seal. After disassembling the fuel injector, replacing the valve core alone can repair the failure of fuel pressure control. It is suitable for the maintenance of large mining excavators, heavy-duty loaders, and long-distance trucks with electronic common rail diesel engines.
Core advantages of this product:
The overall grinding of the quenched and tempered alloy steel is precise, with high hardness and resistance to high-pressure flushing and wear.
The entire valve core is made of high-temperature quenched and hardened alloy steel, and the entire rod body is mirror-polished. It is not prone to scratches or deformation under long-term continuous high-pressure fuel flushing, maintaining a micron-level precise sealing gap for a long time, and preventing fuel internal pressure relief and leakage.
The thickened bottom circular disk seal base completely blocks the fuel reflux.
The widened and thickened circular disk base at the lower end is precisely ground to a high-precision plane, and it is closely sealed with the electromagnetic valve seat, locking the internal high-pressure oil circuit in the closed state, preventing rapid loss of rail pressure after engine shutdown, and improving the performance of cold start at low temperatures.
The multi-stage stepped section rod body, with coaxial motion without offset and jamming
The rod body is equipped with multiple stepped limit structures, restricting the trajectory of the valve core's up and down movement, eliminating radial eccentric shaking, ensuring the valve core's full coaxial reciprocating motion throughout the process, and eliminating single-sided wear and needle valve jamming faults.
The segmented variable diameter rod body design optimizes fuel flow and reduces vortex wear
The segmented and variable diameter structure of the rod body guides the uniform分流 of fuel， reduces the impact loss of high-pressure medium on the sealing contact surface， and improves the long-term durability of the valve core.
The precise sealing end at the top， with a small end that is precisely ground for matching and grinding， has a fast response to the opening and closing of the electronic signal， and precisely controls the injection volume， allowing the engine to idle smoothly and accelerate with linear and uninterrupted power.
Single-piece independent high-pressure flow calibration， no need for manual matching， grinding and assembly
Each valve core is independently tested on the machine for the duration of high-pressure pressure retention， the response of electromagnetic opening and closing， and the flow of fuel circulation. The factory performance parameters are unified， directly matching the corresponding electromagnetic valve cavity of the fuel injector， shortening the disassembly and debugging time of the fuel injector.
