Ubiquitous gate valve has a long history, industrial process control. Originally in the 19th century, its widespread use today, gate has continued to behind the scenes of American industry. In the United States patent is the first valve gate valve. It was born in 1839 in new haven, Charles W. 佩克汉姆。 Although he refused to accept the patents can be used for gate valve, gate valve. It was not until 1840 that the first patent on the gate as we know it today. It is the so-called & other; Cock & throughout; Awarded to Theodore scowden, Cincinnati, Ohio. 先生。 Scowden the unidirectional valve is actually a gate valve with a primitive bolted bonnet. The steam control is a new Industrial Valves design, almost every life from a member of the table from 1850 until the 19th century. The embryonic period America bring many flow valve control the growth of the industry of the future began to make idols: William teller crane ( Crane) ； EdmundH。 lunkenlunkenheimer( ) ; William & middot; Powell ( Powell） ； H。 G。 Ludlow, 鲁上校) ； RufusB。 Chapman ( Chapman) ； Charles & middot; Jenkins ( Jenkins) ； Daniel & middot; Kennedy ( Kennedy) ； Rufus and Pratt ( 普拉特 Katie) 。 All of these patents valve was designed and founded the company, went on to become known as the flow of control. Other inventors are trying to improve gate design, mainly in the area of the disc and seat structure. WilliamJennings in 1896, an engineer & amp; Kitty company pratt, patent and screw-in type seat ring design will still be listed standard in the future in 75, until in the progress of welding technology to tighten device to suspend production. As the industry mature and boiler steam temperature and pressure increase, the valve must keep up with. In some cases, the boiler manufacturers of valve need them, so their own design and manufacture. Until the first decades of the 20th century was started more than 150 - steam pressure 200 psi. Until then, the low pressure applications are easily by brass, iron valves. Cast iron valve handle can also be easily at moderate temperatures in the 350 - A few days before the 400 degrees, high temperature superheater and steam turbines. Innovation power in the industry, operating temperature and pressure in the 1915 - During the period of 1925. This situation has been developed rapidly and materials - a new type of valve Steel. Temperature and pressure of pipeline steel can take that new demands in the middle of the power station. During this time, adopted the design of steel gate valve and appearance, it still is known. With operating temperature and pressure are on the rise, but the new chrome molybdenum alloy/began to adopt the valve structure. Powerful new compounds of chemical and petrochemical industry corrosion caused the challenges of the valve manufacturer. The challenges of the new alloys, for example, Hastelloy, Inconel alloy and 20. The last great progress, in the gate design in the early 1940 s, with the pressure seal bonnet. Reduce the quality of the design pressure and 40% of the total weight of high pressure valves. Pressure seal valve is now the default style of the valve is used to generate electricity. Due to a series of pressure Seal of patent activity for 40 years, 50 years, valve design work has focused on other types of valves, especially ball valve and butterfly valve. Design（ Design) Innovation, the gate valve can through it, but it was piping designer, cost consciousness of procurement staff and factory engineers are still very high.
