Sugao Dongzheng Special Automobile Co., Ltd. has been systematically and standardized in both bottom tank type and oil and gas recovery products. It can provide complete pneumatic and manual control systems, and can be designed and modified according to the needs of users. The company integrates safety, environmental protection, and energy saving into one oil equipment and tanker that meets international environmental safety standards. Our products are well received by users and have now become a designated manufacturer for PetroChina.

The main products of under-loading oil tankers include: manhole covers, oil and gas recovery valves, oil and gas recovery joints, subsea valves (emergency shut-off valves), oil unloading valves, and anti-overflow sensors. The product has the advantages of reasonable design, advanced technology, safety, reliability, energy saving and environmental protection.

1, sea bottom valve

The subsea valve, also called emergency shut-off valve, is installed at the bottom of the tank and is used for down loading and refueling. The operating principle is simple, time saving, safe and environmentally friendly.

The pressure balance type seabed is used for multi-warehouse tank trucks, and separate loading and unloading of different oil tanks is possible. The three-way design intercommunicates piping, reduces the load, the operation is simple, safe and reliable.

The pneumatic shut-off valve is installed at the bottom of the tank body of the tanker truck and can be refueled. The internal pressure of the valve is small and the flow rate is large. There is a cutting groove at the flange of the valve body. When the oil tank accident occurs, the broken groove is at the Unable to carry excessive force, the body pipe and the tank body will be automatically disconnected, while the automatic centering plunger and the durable spring will remain sealed and the medium in the tank will not leak, thus ensuring the safety of the tank. When there is no air or other reason to open, you can open the cylinder piston rod and open it manually.

2, oil and gas recovery valve

The oil and gas recovery valve is a device that recovers the oil and gas generated during the loading and unloading of oil. It can be installed directly on the top tank of the tanker or on the manhole cover. It can pass through a push rod and the bottom of the tank. The valve realizes mechanical linkage opening, and it can also be controlled by the air source to open and close it.

The oil and gas recovery valve can recover all the oil and gas produced by the oil evaporation during loading and unloading into the oil tank in the reservoir area, avoid oil and gas leakage, and condense and reuse oil and gas through other oil and gas recovery devices, thus achieving the purpose of energy conservation and environmental protection.

Features and features:

â—† When the tanker tank is filled, the oil and gas recovery valve is opened, and the rising liquid level pushes up the oil and gas, and returns to the tank in the reservoir area through a series of oil and gas recovery systems.

â—† When the tanker unloads oil, the recovery valve allows the recovered gas to enter the tanker tank. In systems without oil and gas recovery facilities, air is allowed to enter tank tanks.

â—† High tightness ensures the safety of tanker transportation.

â—† Reasonable valve body design ensures high efficiency of oil and gas recovery.

3, oil and gas recovery joints

The oil and gas recovery system of the oil station consists of fire-resisting breathing valve, pipeline flame arrestor, three-way float valve, oil and gas recovery joint, and oil and gas recovery quick connector. It forms a closed circulatory system with the tanker oil and gas recovery system and effectively refuels at the oil station. The recovery and reuse of oil and gas generated in the process avoids the proliferation of oil and gas.

4, under the valve

The bottom valve, also known as the unloading valve, is installed below the side of the tanker for quick unloading. The front-end interface complies with U.S. API Rp1004, which is convenient for connecting with the unloading hose. Hydrodynamics designed the internal structure to minimize internal pressures at high flow rates. The outlet adopts a flat bottom structure and there is no oil leakage when the joint is disassembled, which is safe and reliable. The quick-discharge hose connector is designed with an angle of 70 degrees to facilitate the connection of the hose and effectively increase the service life of the hose.

Features and features:

â—† Integral cast aluminum housing, anodized, replaceable parts.

â—† The flat outlet structure ensures that all liquids are discharged and environmental pollution is reduced.

â—† Two-pole fixed aluminum alloy push rod clearly shows the position of the valve.

â—† Meets the US API RP1004 standard and can interface with API connectors.

â—† Die cast aluminum structure, weight 4.4 kg, increase the effective load.

â—† Viton seal, suitable for high octane fuel and additives.

â—† The fluidics design internal structure minimizes pressure drop at high flow rates.

â—† Stainless steel operating shaft, springs, cams, and stems ensure long life.

5, anti-overflow probe

Uses: Anti-flooding electronic sensors are widely used in a variety of container tanks in the closed liquid filling, in order to prevent the overflow of the liquid spill warning and a safety device, it is installed in the top of the container tank cover, when the oil When the alarm limit is reached, the sensor will alarm automatically.

6, European standard cans cover

Also called the manhole cover, it is installed on the top of the oil tank and has built-in breathing and emergency exhaust functions. The manhole cover can be equipped with oil and gas recovery valves, oil holes, anti-overflow probes, etc. In the process of loading oil, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop the loading of oil. The built-in breathing valve keeps the internal pressure of the oil tank stable during the oil transportation and balances with the external pressure. The design of the dumping overflow prevents the tank truck from being sealed in the event of an accident and the pressure of the emergency exhaust device in the tank. In the case of a sharp increase, it will be automatically opened to release the pressure inside the tank, thereby preventing accidents and greatly improving the safety of oil transport.

Features and features:

â—† Different pressure parameters can be set according to need to ensure reliable breathing function and emergency exhaust function.

â—† Breathing function When the pressure in the tank is higher than the external pressure of 6~8KPa or lower than the external pressure of 2~3KPa, the breathing valve will automatically open, allowing the gas inside and outside the tank to penetrate, which can reduce the pressure difference between inside and outside, and play a safety protection effect. When the difference between the internal pressure of the tank and the external pressure is -2~6KPa, the breathing valve is in the closed state, so that the proper pressure is maintained in the tank so as to avoid waste of the volatile oil.

â—† In the event of accidents and accidents, the spill-proof stopper in the breathing valve automatically seals the passage when the tanker is dumped to prevent the danger of oil leakage.

â—† Emergency Ventilation When the tanker accident occurs in a high temperature environment, the pressure in the tank is effectively released to prevent the tank from exploding. When the pressure in the tank exceeds the external pressure of 21~32KPa, the emergency exhaust device starts to work, and its maximum displacement reaches 7000m3/h, which can effectively prevent the explosion of the tank.

â—† Two-stage opening: After the tank lid is fully opened, release the tank pressure first.

â—† can be locked, configured according to user requirements.

â—† Three auxiliary openings can be used to install the oil hole, anti-overflow probe, and oil recovery valve.
