Double offset Butterfly
Valve
Flange double-eccentric soft-sealed
Butterfly Valve is operated by worm gear to decelerate to drive the disc to
rotate within 90°. It can be applied to cut off or regulate the flow of media. The
valve can be actuated by operating lever, handle wheel, electric actuator or
pneumatic actuator. Underground valve can be operated by an extended Spindle.
No mater operated by electric actuator or pneumatic one, positions where the
valve is opened and closed are all equipped with limit switches and indicating
devices that synchronically show the opening state of the disc.
Being double eccentric, when opened, the
sealed ring of the disc is automatically off-seated after only a little degree
of opening movement. The sealed ring completely bears no external pressure,
which helps the valve keep longer life.
The beveled-sealed surface of the body
forms a linear seal with the rubber-sealed surface, the seal ability is
credible. The position of sealed ring can be adjusted in all directions to
modulate the compression of the seal, which makes the valve able to be operated
by minimum torque.
The disc applies the flying-disc design
with a result of light weight, high rigidity, powerful strength, small flow
resistance and low loss of pressure.
The stem and disc use a positioning pattern
of non-penetration and pin offset to avoid shearing and abrasion of the spline
caused by frequent shifting of the upper stem and to prevent abnormal opening
and closing of the valve.
Automatic assembly and coating product line
and developed process-flow ensure the outstanding ability of anti-corrosion and
flawless appearances of products.
The sealed surface of base uses supersonic
adhesive technology and is coated by stainless steel containing high nickel
whose adhesive strength can reach to 50 Mpa.
Inside and outside surfaces of the body are
coated with electrostatic epoxy resin powder. The coating is even and firm with
good adhesion and excellent anti-corrosion.
Non-toxic epoxy resin powder used comply
with EN sanitary standard .
The coated resin is in accordance with standards
of drinking water.
The valve can be used in drinking water
system, water supply and drainage, heat supply, gas, metallurgical industry,
energy system and pipeline and so on.

Some riders are lazy and say that they don't have to learn this. When they do, they will ask several more in the market. Then you still believe the traffickers. This year, Shen Jiayi has become a steamed stuffed bun, and the sisters of milk tea may have a big stomach. The unloading of the goddess Mito Xiu is also a big aunt... I feel I can't love again... I can trust Who can only believe in yourself! Come back and learn with Xiaoi!
　　 What factors affect the used car price?
The first thing to say is that if you go to the used car market, you should listen to the most valued words of the appraiser is the residual value of used cars, which is a key factor affecting the price of used cars. The higher the salvage rate, the more valuable. Then the following key factors that affect the residual value are concerns. 
   Brand: Under normal circumstances, big brands have high hedge rates, and mainstream brands have high hedge rates.
　　 Models: The larger the vehicle, the more the vehicle is kept. New cars that have just been listed need to pass the test of the market, and the hedge rate is normal, but as the market share, retention and reputation increase, the hedge rate will gradually increase.
　　 Color: black and white silver red common color the most value, individual color car hedge rate is low. However, there are also counterexamples, such as love CD-Europe, Fit, MG3, etc., such as the appearance of stylish personalized cars, the impact of color on the hedge rate correspondingly smaller.
　　 Configuration: The price difference between different configurations of new cars is very large. But to the used car here, the gap is very small. So when you buy a new car, try to consider the low-end models, in turn, buy a used car is to buy a high value for more.
　　 Age and number of miles: According to the number of years of use and the number of kilometers traveled, discounts will decline in inverse proportion. If one of the two items is significantly higher than the other, it is assessed according to the higher one.
　　 Several handcarts: The greater the number of vehicle transfers, the lower the residual rate. When assessing, the car buyer needs to know the ownership of the vehicle in detail.
　　 Maintenance: The cost of maintaining the car in 4S will be slightly higher than that in the repair shop, but it will have little impact. 
   Which estimation methods are practical and reliable?
There are a variety of online methods. Xiaoi has carefully selected these kinds of materials for everyone to use.
　　 Method One: This is a more common method. It is to use the new car price as a reference to calculate the used car price according to the depreciation rate. The base price is the current new car price for the cheapest car of the same model.
Under the premise of no major changes, the automobile service life is assumed to be approximately 10 years. At the time of evaluation, the new car will be depreciated in 10 years divided into 3 years to 4 years to 3 years. The depreciation rate is 11 per year. %, 10% and 9%.
In addition, according to the configuration can be added to the appropriate price: For example, many old car dealers clearly stated that the power window, electric rearview mirror plus 1000 yuan, central locking anti-theft device plus 500 yuan, with ABS, dual airbag plus 2000 yuan, leather Seat plus 1,000 yuan, plus skylight plus 1,500 yuan......
　　 Method Two : "The Rule of 54321," which is calculated in terms of kilometers. The basic price is the same as the above method. A car has a useful life of 300,000 kilometers and is divided into 5 sections of 60,000 kilometers each. The value of each section is 5/15, 4/15, 3/15, 2/15, 1/15 of the new car price. . Assume that the new car price is 300,000 yuan and that it has traveled 100,000 kilometers, then the value of this car is 300,000 yuan (3+2+1)÷15=12 million yuan.
　　 Method 3: Use an assessment calculator. There are many factors that need to be considered when assessing used car prices. If riders are not comfortable with their valuations.
