Development of Chinese valve industry

Many Chinese valve industry chain, but non-valve power. To see the whole country has entered the ranks of the world's great powers valves, but the product quality from the point of view of the valve power is still a long gap. Production industry concentration, low-end products supporting the valve research and development capabilities, the valve industry and low level of manufacturing technology still exists, import and export trade deficit expanded.
The coming years will be the speed of the shock valve industry, a direct consequence of this is to bring high-speed shocks causing the valve cabinet brands to expand the trend of polarization camp. Really be able to survive in the market of the valve business is absolutely not so much. But this high-speed oscillation valve industry will bring tremendous opportunity to shock the result will make the market more rational operation.
Localization of the road-end valve abnormality "bumpy"
Valve industry in national economic development, as an important part of the manufacturing sector to prepare, play a very important role. Since the level of domestic and international advanced valve manufacturing is still a gap compared to the level, a lot of high-parameter, high temperature and high pressure, high level of critical valves former pound has been dependent on imports, in order to urge the valve localization
Actively adopt international standards for product design; absorbing foreign outstanding design structures (including patented technology); product testing, performance testing in strict accordance with international standards; absorption of foreign advanced production technology and experience emphasis on research and application of new materials; clarify imports high parameters valve product technical parameters and working conditions, etc. is to accelerate the localization process, promoting the valve product updates, the full realization of localization only way valve.
With the accelerated pace of the valve industry restructuring, the industry will be the future of the vsafety gas valveand product competition between brands, product development to high-tech, high-parameter, strong corrosion resistance, high-life direction, only through constant technological innovation, development new products, technological innovation, in order to gradually increase the level of product technology, to meet the domestic means of supporting the full realization of the gas valve localization. China's valve manufacturing industry in the huge demand environment, will show better prospects for development.

Gas valve

Install on the burner gas manifold connected to the valve for regulating the amount of gas called the gas valve.
When the stove in the combustion period, the combustion valve (also known as combustion ram) and Bbq Gas Valves (also known as gas gate) after full, open valve, by adjusting the valve opening at different angles to adjust the amount of gas in order to ensure stove operate smoothly. Automatic burning stove, the electrical control of the valve, according to the required amount of gas stove, automatically adjusted

Classification of the safety valve

Pilot Safety Valves structure are two major categories: spring and leveraged. Spring means sealing valve and valve seat by spring force. Leveraged rely on leverage and weight forces. With the large capacity needs, harboring a pulse valve, also known as the pilot valve, the main valve and the auxiliary valve. When the pipeline medium pressure exceeds a predetermined pressure value, the auxiliary valve to open, the media along the catheter into the main valve and the main valve is opened to reduce the media pressure increased.
Pilot operated safety valvee emissions depends on the caliber of the valve seat and valve opening height, it can be divided into two types: Weiqi opening height is the seat diameter (1/20) - (1/40), the entire Kai It is (1/3) - (1/4).
In addition, with different requirements, there are enclosed and not enclosed. Closed namely discharged media is not compromised, the entire exhaust outlet along a predetermined, generally used for toxic and corrosive media. Enclosed is generally not used for toxic or corrosive media.

the composition of the hydraulic system

After the oil flow manifold holes of play to produce a certain pressure loss, its value is an important symbol to reflect the block design quality and level of integration means, obviously, hydraulic cutting machine the less manifold hole in the process, additional pressure loss smaller.
Hydraulic manifold features are there?
Hydraulic manifold consists of integrated hydraulic components (such as stack valves). When ferrule use for one wire hose the composition of the hydraulic system with integrated hydraulic components, without additional connection block, which is connected to the body's own body as a direct composite made. and then find DIN2430A mounting surface iFeature in the feature library, the pop-up dialog box shown in Figure 3, first picked up on the hydraulic manifold surface, and then need to specify the angle in accordance with the design, click "Finish." In order to achieve a reasonable arrangement manifold surface around the hydraulic valve and its proper arrangements through the hole, you can follow the contours of the size and location of the oil port of pre-made components hydraulic valve model, the relevant view on the manifold arrange a suitable location.

Use gas valve

gas valve is a safety device supporting a new gas pipeline projects; to cut off, turn on, adjust the gas pipeline, has good control properties and close the sealing performance; suitable for city gas, liquefied petroleum gas, natural gas, a variety of gas medium pipeline oxygen.
Bbq Gas Valves are widely used for a variety of city gas pipeline network system media pipeline gas, liquefied petroleum gas, natural gas, oxygen, etc; drive in the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, can realize remote control and automation.

Safety gas aluminum valves

① before the safety gas aluminum valves factory, should one by one to adjust the opening pressure setting value of user requirements. If the user make spring working pressure level, the general should be adjusted lower limit of the pressure level of the factory.
② user before the safety valve is installed on the protected equipment or before installation, you must re-adjusted at the installation site, in order to ensure that the setting pressure relief valve to meet the requirements.
③ spring working pressure level within the range of nameplate by the rotation adjustment screw to change the amount of compression spring can be adjusted to opening pressure.
④ Before the rotation adjustment screw, the Water Heater Gas Valves inlet pressure should be reduced to 90% of the opening pressure of the following, in order to prevent the valve is rotated when the rotation adjustment screw, which damage the sealing surface.
⑤ To ensure accurate opening pressure value, should make adjustments in the medium conditions, such as media type, temperature as close to the actual operating conditions. Media types to change, especially when the media is not the same accumulation of state (for example, from liquid into vapor), the opening pressure changes often. When the temperature increases, the opening pressure is generally decreased. It is adjusted at room temperature and used at high temperatures, the set pressure value at room temperature should be slightly higher than the required opening pressure. To what extent the valve structure and material selection have a relationship should be based according to the manufacturer's instructions.

Safety valve


Safety valve is to synchronize the rotation of the coupling drag, friction and will not have any contact with. Gas Heater Control Valve to reduce the impact of vibration motor, and the impact caused when the vibration of the motor. In the medium through, the amount of lubricating the inner and outer magnetic rotor will be relative to the Pilot operated safety valve and the motor has a protective effect. Valve actuator in the case of work, but also may appear stuck phenomenon, magnetic rotator will automatically fall off, to protect the body does not hurt.
