Axial Flow Control Valve Manufacturer in China
Axial flow control valve. The valve body includes the valve outer body and the valve inner body, which are cast or forged as a whole, have a streamlined and evenly symmetrical free flow path, reduce the impact of local high-speed flow, turbulence, jet flow, etc., and improve the stability of the valve. Axial flow control valve: The valve body is cast with a clear flow arrow, and the series products adopt axial flow structure design, which maximizes the flow channel capacity per unit diameter, reduces the flow channel resistance, and greatly reduces noise and turbulence formation.
Liangzheng was established in 2003 and has Changzhou Gas Valve Production Base and Binhai General Valve Production Base. Tianjin Water Control Valve Production Base, Fujian Casting Production Base, etc., with a total area of 100 mu, more than 350 employees, after years of efforts and development, is a valve enterprise integrating scientific research, design, manufacturing, sales, and service.
The Structure of the Valve Seat of the Axial Flow Control Valve
The valve seat adopts a pressure balance structure. After the valve is closed, the dynamic force of the fluid medium on the valve seat and the pressure difference between the two sides of the valve before and after the valve can be ignored. Even large-diameter valves can be operated with a smaller torque actuator under high pressure drop conditions. Therefore, compared with the traditional control valve, the use of a smaller torque actuator can achieve the purpose of smoothly switching the valve. The valve seat adopts a split welding structure, which can not only reduce the weight of the valve seat and friction force, but also reduce the difficulty of processing and ensure the precision of processing.
Company Equipment Introduction
The company has obtained the “TS” Class A certification of the special equipment manufacturing license of the People’s Republic of China, ISO9001 international quality system certification, ISO14001 environmental system certification, OHSAS 18001 occupational health and safety management system certification, API certification of the American Petroleum Institute and other certificates.
Axial Flow Control Valve Application Scenarios
The driving part of the axial flow control valve adopts bevel gear drive, and both the valve stem and the push rod have 45° bevel gears. The bevel gear drive design reduces the overtravel of the valve.
The axial flow control valve adds a dual-guidance structure to the valve seat in high-pressure conditions, which greatly improves the leakage level of the valve and also increases the service life of the soft sealing ring. It is not easy to form slag in the valve chamber, which reduces the number of leakage points.
Axial flow control valve. The valve stem transmission pair adopts a 90° vertical rack and pinion engagement. The valve stem moves vertically, driving the push rod and the valve seat connected to the push rod to move horizontally, thus achieving the purpose of valve opening and closing. The rack and pinion transmission form has high transmission efficiency, stable transmission, and high precision.

In this axial flow control valve, the sealing material is selected as a balanced sealing ring, which is a structure of PTFE + metal spring. The sealing surface performance is reliable, the friction coefficient is small, and it is not easy to be damaged. The greater the pressure, the better the sealing performance. It realizes zero external leakage of natural gas from the valve stem and does not scratch the valve stem, ensuring that it can be used in harsh environments.
This axial flow control valve, the valve seat and the valve seat adopt a combination of soft-hard sealing, in which the valve seat adopts the form of 17-4PH + Stellite alloy sealing surface, and there must be a hardness difference between the soft seat and the hard seat. The metal seat does not need to be welded, so the metal valve seat seals.
The Hardness Difference Between the Transmission Parts
To prevent axial flow control valve from being stuck during operation, the abnormal working condition caused the valve to be stuck and not move; for example, the pipeline was not cleaned properly, resulting in the presence of residual welding slag and other hard particles. All the mating surfaces of the axial flow regulating valve are designed with a hardness difference, and the hardness difference is not less than HB50.
There is a linear motion duplex between the valve stem and the sleeve, and it is easy to have a lock-up phenomenon due to high pressure, dirty medium, etc., so our company designs a certain hardness difference between the valve stem and sleeve. The valve stem adopts 17-4 PH precipitation hardening treatment and surface nitriding treatment, which greatly improves the hardness of the valve stem. The sleeve adopts Q5n6.5 -0.1 series bronze alloy, which is much softer than the valve stem, thus avoiding the phenomenon of valve lock.
