Conductive Quick Connector with double seal ring radial seal structure, rubber modified by O - ring, mainly for fluid and the physical, chemical properties of custom, prevent aging, corrosion, swelling; O - ring have intermediate spacer ring separated, two sealing rings of the corresponding event space, the rubber matrix bonding does not occur, the external O-ring using synthetic rubber, enhanced mechanical properties, prevent air aging. Sealing ring and a spacer ring through the outer ring of the elastic bayonet device firmly fixed in the shell, does not produce seal off and shift phenomenon produced. Greatly ensure the safety of the seal.
Quick Connector composed of a connector housing, O - ring, O - ring, a spacer ring, outer ring, a self-locking buckle, when another pipe adapter (male connector) insert joint, because of the self-locking buckle has certain elasticity with buckle fastener can connect the two connectors together, then pulled back, ensure that the installation in place so fast joint can play a role. Disassembly and maintenance as long as the first to promote the positive joint and press and hold the self-locking buckle at both ends of the buckle buttons, the self-locking expansion in the middle, you can easily pull out the connector, re connect forward should use SAE 30, heavy oil lubrication.
The electric conduction fast joint is mainly in the medium of methanol gasoline and ethanol gasoline.. It has the overall structure, the best sealing effect. Can work under pressure 10bar. The engine area temperature is suitable for the short time of the -40 up to +110 to reach the +150 degree (about half an hour).

Regulating valve development process
The development of the control valve has been seven or eight decades since the beginning of the 20th century and has successively produced ten categories of control valve products, self-operated valves and positioners, etc. The development history of the valve is as follows: 1920s: The original stability Pressure control valve available. 1930s: The "V" notch double seat valve and single seat valve are the products that come out. 40's: There locator, further generation of new control valve, there Diaphragm valve, angle valve, butterfly valve, ball valve and so on. 50's: the ball valve to get larger promotion, three-way valve instead of two single-seat valve into the system. 60's: In the domestic product of the above series of improved design and standardization, standardization, before we have a complete range of products. Now we are still using a large number of single-seat valve, seat, angle valve, three-way valve, diaphragm valve, butterfly valve, ball valve seven products is still the level of the sixties products. At this time, foreign countries began to introduce the eighth structural adjustment valve - sleeve valve. 70s: Another new structure of the product - the advent of eccentric rotary valve (the ninth category structure of the control valve varieties). Sleeve valve in this period is widely used abroad. The late 70s, the domestic joint design sleeve valve, so that China has its own sleeve valve product line. 80s: early 80s due to reform and opening up, China successfully introduced petrochemical plant and control valve technology, the sleeve valve, eccentric rotary valve has been promoted, especially the sleeve valve, a great alternative to the single, double seat valve potential , Its use is more and more widely. In the late 1980s, another significant development of regulating valves was Japan's Cv3000 and fine control valves. They were structurally modified from single spring pneumatic diaphragm actuators to multi-spring diaphragm actuators. The structure of the valve was improved rather than changed . Its distinguishing features are a 30% reduction in weight and height of the control valve and a 30% increase in flow coefficient. 90's: 90's focus is on reliability, special difficult products, improvement, improvement. By the late 90s, Hualin Company introduced the tenth structure of the product - full-featured ultra-light valve. Its salient features are a break in reliability, functionality and weight. Functional breakthrough - the only one with full-featured products, so a product can replace many of the features of incomplete products, so that the selection of simplified, easy to use, breed simplification; breakthrough in weight - a single product than the leading Seat valve, double seat valve, sleeve valve light 70 ~ 80% lighter than the fine valve 40 ~ 50%; reliability breakthrough - to solve a series of traditional valve unreliability factors, such as the reliability of the seal, Positioning reliability, the reliability of the action. The advent of the product, so that China's control valve technology and application level reached the advanced level of the late nineties; it is a major breakthrough in the control valve; especially electronic full-function ultra-light valve, will become the next century, the control valve Mainstream.
