Ball valve open-close part for sphere, through a sphere around the body center for rotation to achieve open, closing a valve.Used for intercepting and change the flow distribution ratio or quick opening and closing. Its characteristic is wear-resisting, good sealing, light switch, long service life.Widely used in petroleum, chemical industry, power generation, paper making, aerospace and other fields. The advantages of the ball valve: 1, with the bottom flow resistance 2, realize completely sealed reaction in the high pressure and temperature range 3, can achieve rapid opening and closing and no impact to operation 4, not easy to get stuck at work, so reliably used in corrosive medium and low boiling point 5, double sealed more reliable 6, when the ball valve is fully open and close, sealing surface and the dielectric isolation, so the high speed won't bleed air seal face erosion by the media. 7, compact structure, light weight, can be thought of as the most ideal valve ball valve is used for low temperature medium. 8, all welded body ball valve, can be directly buried underground make internal valve from erosion, the highest service life can be up to 30 years. Our advantage: The company on the basis of combined with the structural advantages of ball valve, ball valve leakage protection aspects focus on improvement, the first is to use three free maintenance o-rings, adding self-styled mat, stainless steel valve stem to prevent rust and on both sides of a sphere with butterfly spring, easy to cause the medium leaking key protection area.And the company can according to customer demand, customized. The company in the valve design and manufacturing of 32 national patents, ISO9001:2000 secondary quality system certification and CE, ANSI, UN and other international certification.Is the present domestic most professional heating valve manufacturing enterprise. wooden box with filling or according customer's requirement
Single flange fully welded ball valve design reasons that other valves after pipeline installation , you can not directly install fully welded ball valve , according to the circumstances, Hebei Tongli company specializing in a single flange fully welded ball valve. Flanged ends can and other valves, or pipe flange connection, and the other end connected by welding , easy to replace the valve flange end . Single flange fully welded ball valve applications : City gas : gas export pipeline , the main trunk and each branch supply pipes. Central heating : Large heating equipment output pipelines, trunk , branch . Heat exchangers : Pipeline and its opening and closing the loop . Steel plant : a variety of fluid pipes, exhaust pipes, gas and Heat supply pipelines, fuel supply pipe. A variety of industrial equipment: various heat treatment pipes , industrial gas and heating pipes. Single flange fully welded ball valve construction and design : Single flange welded ball valve is completely designed and manufactured in accordance with API6D , fire anti-static . Stem lengthened according to user requirements , body and other metal parts used in all spheres of high-quality forged materials to ensure the quality and strength of ball . Sphere with packing boxes or support plate fixation. Packing boxes or support plate fixed ball can eliminate bending media sphere force acting on the valve stem to produce , so the stem is exposed only torque. And in the sphere of fixed low-friction Teflon around Le composite bearings. Smooth operation of the valve , a small switch torque , easy to operate. Seal is a unique two soft seal and metal seal form triple sealing . Ensure reliable sealing, safe to use. Long-life , maintenance-free . Single flange fully welded ball valve Features: 1. single flange body structure , individual welding, there will be no external leakage. 2. the valve seat by a PTFE sealing ring and spring changes in the composition of the pressure and temperature adaptability in the range does not have any leaks. 3.anti- leak stem structure at the bottom of the stem has a self-proclaimed PTFE seals and an O-ring, there are two O -rings above , consisting of two PTFE gaskets to ensure no leakage . 4.the body is light and easy to heat . 5.can be selected according to a single flange welded ball valve flange diameter pipeline , construction and design requirements can adjust the length of the body and stem height. 6.the sphere is very precise precision , easy operation, no adverse interference . 7.there are two kinds of welded and flanged connections . 8.Operation: Lever , gear ( vertical / horizontal ) 9.in the case of valves used in normal operation , the warranty period is 20 years. wooden box with filling or according customer's requirement
Hebei Tongli company specializes in fully welded ball valve turbo R & D and testing , to learn foreign advanced technology, combined with the actual situation developed, with domestic instead of imported fill the gaps . Jinke power turbine with fully welded ball valve equipped with advanced production lines and processing, " Jinke with force " to become a famous domestic brand valves , with top production equipment and technical engineers . Hebei Tongli production turbo fully welded ball valve temperature control range is generally : -30-150 ¡æ. Fully welded ball valve turbo widely used in long-distance pipeline main areas of hot water, oil , heat, chemical and thermal power pipe network . Fully welded ball valve turbo caliber and temperature corresponding table: Fully welded ball valve turbo anatomical diagram: Fully welded ball valve turbo advantages: The first major advantage : all-welded valve body and the carbon-reinforced Teflon gaskets constituted frequent operation can be performed , and impurities in the case of chemical substances can guarantee a long operating life . Exquisite workmanship, fine stainless steel grinding balls can guarantee decade openable and closable , reliable , quality , safe , easy to install budgetary savings . The second big advantage : all-welded ball valve turbo float structure, slope to ensure flexibility seals pressed on the ball , even under pressure instability, the valve can guarantee a reliable airtight . The third major advantage : anti- leak stem structure uses two "o" ring, so the stem turn freely and sealed tight, no leaks. Fully welded ball valve turbo features : 1.does not require maintenance , adjustment and lubrication, easy to install, long-term reliable operation. 2.Stem not only lengthen but also through after finishing grinding production, with excellent sealing performance and corrosion resistance .Ease of insulation 3.operating handle can be removed , reversing the installation. 4. The body without the heavy and unreliable cast components . 5. Install the adjusting mechanism is very simple. wooden box with filling or according customer's requirement
