Description
OPW automatic vapor recovery Fuel nozzle fuel dispenser parts
The fueling nozzle is designed to open & close the oil circuit and the gas circuit at the same time, effectively ensuring the overall airtightness of the gas circuit. It have Strong versatility, compatible with brands such as ZVA/HUSKY, Gilbarco Veeder-Root, Franklin, etc.
JH-VRQ-70 vapor recovery type Fuel nozzle is an vapor recovery type fuel nozzle with beautiful appearance, stable performance and strong versatility. In addition to maintaining the advanced technology level of foreign countries, this type of fuel nozzle has made unique design and improvement for the diversity of automobile fuel tanks in Chinese market, so as to serve the domestic market with more professional and personalized products. It can be applied to both centralized and decentralized Vapor recovery systems.
1、Safe and stable working performance:
Unique barrel design, more suitable for the Chinese market automobile fuel tank diversity, can effectively avoid the occurrence of abnormal nozzle jumping, work more stable and reliable. The oil nozzle needs to be opened only when there is oil pressure to prevent accidental oil spraying. The main valve opens against the oil flow, which enhances the safety factor during use. Low air and liquid resistance design. Accurate flow control: users can precisely control the flow rate of the fueling nozzle and the amount of fueling according to their needs.

3.Working Principle
Start the fuel dispenser. Oil through the pipeline from the inlet into the nozzle body 1, by the pressure of oil pressure, pressureless self-sealing valve 3 into the working state, pull up the handle 9. linkage lever 7 Drive the main valve switch 2 open (i.e., refueling nozzle into the working state). When the oil passes through the negative pressure valve 4, negative vacuum is generated, and the air enters into the pressureless self-sealing valve 3 from the self-sealing port 11, and the air circulation ensures the normal work of the pressureless self-sealing valve 3, such as blocking the self-sealing port and forming a vacuum in the pipe to achieve the purpose of self-sealing. Under the suction of the recovery pump, the sprayed vapor from the vapor recovery inlet enters the nozzle body through the main valve switch 2 to recover to the designated recovery device.
4. Performance characteristics
4.1 The refueling nozzle is equipped with a gas sealing cover, which can effectively improve the effect of vapor recovery.
4.2 Built-in vapor recovery channels.
4.3 Standard component design, parts are easy to replace (barrel).
4.4 Applicable to self-service prepaid gas stations.
4.5 Adopt coaxial 304 stainless steel barrel, make the fueling nozzle more durable, cut design with shear groove (meet UL standard), can effectively protect the fuel dispenser.
4.6 The main valve opens against the oil flow for greater safety.
4.7 The nozzle adopts the design of pressureless self-sealing structure, there are nozzles need to have oil pressure in order to open the work, the security is stronger, in line with UL842 standard.
4.8 Comply with safety and environmental protection requirements.
4.9 Extremely versatile, compatible with ZVA, HUSKY, Videolut, Heineken and other international brands of gasoline dispensers, all domestic gasoline dispensers.
5.Precautions for the use of oil nozzle
5.1 When refueling, you should follow the formal steps and drive slowly from a small gear to a large one;
5.2 The hood at the fuel nozzle barrel should completely cover the fuel tank opening of the vehicle. So as not to lower the fuel
Gas Recovery Efficiency;
5.3 Don't take out the fuel nozzle immediately after refueling, but gently shake it at the mouth of the car's fuel tank
Grease nozzle to drain any gasoline left hanging from the mouth of the grease nozzle;
5.4 After the tank is filled and the nozzle is sealed, do not force refueling, if you force to continue refueling, gasoline liquid is easily sucked into the oil
5.5 The oil nozzle should avoid collision, knocking and dropping, and often clean the self-sealing hole of the barrel and the vapor recovery hole.
