In 2016, the Yellow Sea pickup truck achieved a double harvest of sales and profitability, and Huanghai pickup products were unanimously recognized by the market. At the beginning of 2017, Huanghai pickups got a good start, and the overall sales volume increased sharply. On the one hand, it benefited from the continuous launch of its upgraded and redesigned products; on the other hand, it has an inseparable relationship with Huanghai pickup trucks in marketing strategy.
At the beginning of the new year, the Yellow River pickup marketing company has developed new strategies. In order to fully mobilize the enthusiasm of the dealers' first-line sales team, comprehensively tap the market potential, invest heavily in the market to continue to increase, and develop a first-line sales team incentive with a monthly assessment cycle. The award and the over-the-counter award for the task index of more than 120% in the two-month assessment have achieved the overall growth of the 40 mainstream dealers' task indicators.
In 2017, the substantial growth of the Yellow Sea pickup truck year was benefited from the consumption demand, thanks to the release of potential energy inspired by the new marketing strategy, and the core competitiveness of its products.
Huanghai Automobile has steadily promoted new products according to product planning, and has launched a number of new models such as N2, N2S, N2 single-row pickups, N1 single-row pickups and the new N1S. Subsequently, the car market was closely followed, and modified models such as pickup trucks and fishing carts were introduced.
Huanghai pickup has become one of the most comprehensive, most comprehensive and optimal pickup brands in China. It has enriched the product line to the maximum extent and provided more diversified car purchase options for domestic pickup users. At the same time, the product models launched in the market competition are eye-catching, with complete varieties and obvious advantages, which is the main factor for the substantial growth of Huanghai pickup truck performance.
Recently, a new series of N3 pickups under the Yellow Sea has been produced in small batches, subverting the past and pursuing the lead. It is the original intention of the Yellow Sea N3 pickup project. It is a sublimation of the essence of the European and American high-end big pickups in terms of appearance. The high-level experience in the pickup culture is strengthened, and the subversive products in the domestic pickup truck models are reflected in the configuration of the demand for high-end luxury SUVs. Keeping up with the urgent demands of the Chinese people for the high-end big pickup truck, it has created a new cognitive demand for high-end big pickup trucks.
It is believed that with the listing of the N3 pickup truck, the sales volume of the Yellow Sea pickup truck will be further improved in 2017.
A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball Check Valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check Valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.
Ball check valves are often very small, simple, and cheap. They are commonly used in liquid or gel minipump dispenser spigots, spray devices, some rubber bulbs for pumping air, etc., manual air pumps and some other pumps, and refillable dispensing syringes. Although the balls are most often made of metal, they can be made of other materials, or in some specialized cases out of artificial ruby. High pressure HPLC pumps and similar applications commonly use small inlet and outlet ball check valves with both balls and seats made of artificial ruby, for both hardness and chemical resistance. After prolonged use, such check valves can eventually wear out or the seat can develop a crack, requiring replacement. Therefore, such valves are made to be replaceable, sometimes placed in a small plastic body tightly-fitted inside a metal fitting which can withstand high pressure and which is screwed into the pump head.
There are similar check valves where the disc is not a ball, but some other shape, such as a poppet energized by a spring. Ball check valves should not be confused with Ball Valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow.
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount, known as the pressure differential, for the check valve to open allowing flow. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position.
A swing check valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle. Although swing check valves can come in various sizes, large check valves are often swing check valves. The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. It then remains open until the tank drains and the flapper falls due to gravity. Another variation of this mechanism is the clapper valve, used in applications such firefighting and fire life safety systems. A hinged gate only remains open in the inflowing direction. The clapper valve often also has a spring that keeps the gate shut when there is no forward pressure. Another example is the backwater valve (for sanitary drainage system) that protects against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems connected to combined sewerage systems and in rainwater drainage systems. It may be caused by intense rainfall, thaw or flood.
A stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. In addition to closing in response to backflow or insufficient forward pressure (normal check-valve behavior), it can also be deliberately shut by an external mechanism, thereby preventing any flow regardless of forward pressure.
A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.
An in-line check valve is a check valve similar to the lift check valve. However, this valve generally has a spring that will 'lift' when there is pressure on the upstream side of the valve. The pressure needed on the upstream side of the valve to overcome the spring tension is called the 'cracking pressure'. When the pressure going through the valve goes below the cracking pressure, the spring will close the valve to prevent back-flow in the process.
A duckbill valve is a check valve in which flow proceeds through a soft tube that protrudes into the downstream side. Back-pressure collapses this tube, cutting off flow.
A pneumatic non-return valve.
Multiple check valves can be connected in series. For example, a double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines. There are also double ball check valves in which there are two ball/seat combinations sequentially in the same body to ensure positive leak-tight shutoff when blocking reverse flow; and piston check valves, wafer check valves, and ball-and-cone check valves.
