The elastic soft sealing gate valve features: 1 flat style seat: the traditional valve tube after washing often pass for foreign objects such as stone, wood, cement, paper and other debris deposited on the valve at the end of the groove. Easy to cause can not be closed tightly and the formation of water leakage phenomenon, soft seal gate valve with the same low part of the design of the same water pipes, is not easy to cause debris accumulation, so that fluid without resistance. 2 overall package plastic: valve plate with high quality rubber as a whole, the outsourcing of plastic, the domestic first-class rubber vulcanization vulcanization after the valve plate to ensure accurate geometry, and the rubber and ductile iron gate connection is firm and not easy to fall off and good elastic memory. 3 corrosion resistance: valve body using powder epoxy resin coating, can prevent the body from corrosion and rust, and can be used for sewage system. 4: no fragmentation of traditional cast iron garden gate often hit foreign objects, collision or overlap caused by the fracture phenomenon. This situation has been greatly reduced due to the use of ductile iron in the valve. 5 three "O" ring ring: as the valve stem by three "0" ring ring seal design, can reduce friction when the switch is Water Leakage lightning can significantly reduce the phenomenon of construction of replacement seals off the water. 6 help to drink: due to the internal body with non-toxic epoxy resin coating, the inner and outer surface of the gate are completely coated with rubber without the appearance of rust or corrosion phenomenon, can be used for drinking. 7 Casting valve: valve body casting, precise geometry makes the body without any internal finishing to ensure that the valve seal. 8 light weight: This valve is made of ductile cast, the weight is less than the traditional weight loss of about 20%-30%. Convenient installation and maintenance. The elastic valve seat seal is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The main domestic well-known manufacturers of Hebei Heng valve equipment Co. Ltd. The company is the Ministry of machinery industry, the Ministry of chemical industry, China Chemical Equipment Corporation designated management of production enterprises. Its products in the industry has a certain price advantage and technological advantage.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
The detection performance of elastic soft sealing gate valve: 1 valve of a standard high-volume manufacturing, testing should be entrusted to an authoritative body to the following performance: the valve in the opening and closing torque pressure condition; the pressure in the working conditions, to ensure the continuous opening and closing the valve tightly closed times: the valve in the pipe condition the flow resistance coefficient detection.2 valve should be at the factory before the following test: the valve in the open position, the valve body should bear the value of two times the working pressure of the internal pressure of the valve closed position detection; and both sides were to withstand 1.1 times the value of the valve working pressure, no leakage; but the metal sealing butterfly valve, leakage value is not greater than the relevant requirements.
Flexible soft sealing gate valve general requirements: 1 flexible soft sealing gate valve specifications and categories, should be consistent with the requirements of the pipeline design documents. 2 elastic soft seal gate valve model should be specified on the basis of the requirements of the national standard. If the enterprise standard, should indicate the type of relevant instructions. 3 elastic soft sealing gate valve working pressure requirements than pipeline working pressure, without affecting the price of the premise, the valve can withstand the working pressure should be greater than the actual pipe work pressure; any one side of the elastic soft sealing gate valve closing conditions should be able to withstand 1.1 times the value of the valve working pressure without leakage; valve opening next, the valve should be able to withstand two times the working pressure valve requirements. 4 flexible soft seal gate valve manufacturing standards, should be based on the national standard number, if the enterprise standards, procurement contracts should be attached to the enterprise file. This type of valve in the pipeline should generally be installed horizontally.
