JLK fixed throttle

Product Type: JLK Product Name: JLK adjustable throttle, JLK fixed throttle Product caliber: DN10-250 fixed throttle Description: throttle JLK, JLG series) is designed to meet SY / T5127-2002 , API Spec 6A and API Spec 16C requirements, according to the structure can be divided into fixed adjustable throttle and throttle, fixed and adjustable throttle body throttle body can be interchanged. Press the action principle is divided into manual throttle and hydraulic throttle. Valve cover and valve body is metal to metal seal. Wherein the fixed throttle nozzle, adjustable throttle valve stem, plug and seat are made of carbide manufacturing, with wear resistance to erosion, reliable and so on. According to the functions can be divided into a needle-shaped adjustable throttle barrel adjustable throttle. Needle variable throttle is mainly used for oil (gas) wellhead equipment for oil (gas) volume adjustment; tubular adjustable throttle throttle manifold is mainly used to control the well with casing pressure fluid. Minimum material level material requirements Body, bonnet stem, seat AA general use carbon or low alloy steel, carbon steel or low alloy steel is generally used BB or low alloy steel commonly used stainless steel DD CC acidic environment of steel or low alloy steel or low alloy steel EE acidic environment or low alloy steel FF acidic environment of stainless steel HH acidic environment corrosion-resistant alloys corrosion-resistant alloys Note: a) Press NACE MR0175 standard definitions b) comply with NACE Standard MR0175 fixed Throttle Design Standard: Valve Manufacturing: GB12235-1994 valve test: GB / T13927-1992 operating parameters for the media temperature performance requirements applicable material specifications Grade Standard Grade 113 / 16--71 / l3 oil, gas, water, etc. -29 ℃ ~ 121 ℃ PR1, PR2 AA, BB, CC, DD, EE, FF, HH PSL1, PSL2 API Spec 6A when the use of maintenance and precautions 1, products factory have made a strength test and sealing test, except using Other connections should be maintained at both ends outside the initial state. 2, medium flow mark, 3, as a result of damage to wearing parts and leakage, to the timely replacement of wearing parts of this series on housing. 4, the repair process, to clean the valve cavity, to protect the seal ring assembly, to prevent a bad knock and cause leakage. While adding a certain amount of grease in the moving parts. 5, the valve deactivation during storage, should the valve is in the closed position, the long-term storage should be dry and ventilated place, regular inspection and maintenance.
