Soft sealing gate valve is the replacement of traditional products,compensation by using the elastic deformation of the gate produce small quantities, to achieve a good seal, the valve has a light switch, reliable sealing, good elastic memory and long service life and other advantages, can be widely used in water, sewage,construction, food, medicine, metallurgy, electric power, textile,energy systems, fluid pipeline regulation and closure devices as.

Characteristic.

· flat style seat

The traditional valve tube after washing often pass for foreign objects such as stone, wood, cement, paper, and other debrisdeposited on the valve at the end of the groove. Close but not close easily lead to the formation of Water Leakage phenomenon,soft sealing gate valve at the bottom with water using the same flat design, not easy to siltation caused by debris, the fluid unimpeded

· overall package glue

The valve plate made of high-quality rubber as a whole, the outsourcing of plastic, making the domestic first-class rubber vulcanization after the valve plate vulcanization to ensure accurate geometry, and the rubber and nodular cast iron gate connection is firm, not easy to fall off and good elastic memory.

· corrosion

The body adopts epoxy coating powder, can prevent the corrosionand rust, and can be used for sewage systems.

· no fragmentation

Traditional cast iron gate valve are often hit by foreign objects,collision or overlap caused by the fracture phenomenon. Because the valve to switch to ductile iron, this situation has been greatly reduced.

· three "O" seal ring

As the valve stem by three "0" ring ring seal design, can reduce friction when the switch, Water Leakage phenomenon and cangreatly reduce construction of replacement seals off the water.

· help to drink

Due to the internal body to non-toxic epoxy coating, gate of the inner and outer surfaces are rubber coated and will not appear completely rust or corrosion of water available to drink.

· casting valve

Valve body casting, precise geometry makes the body without any internal finishing to ensure that the valve seal.

· weight

The valve is made of ductile cast, lighter in weight than conventional valve about 20%-30%. Convenient installation andrepair.

Parameter definition

   1 nominal diameter: (nominal diameter), also known as the average diameter (mean outside diameter), said the symbol DN, is the general caliber pipe and pipe accessories. The same nominal diameter of the tube and pipe accessories can connect with each other, with interchangeability. It is not a real sense of pipe diameter or diameter, although its value is closer with pipeline diameter or equivalent, in order to make the pipe, tube connection size uniform,with nominal diameter (also called nominal diameter, nominal diameter). 

Belt guides

    For example, according to the thickness of welded steel pipe can be divided into thin-walled steel, general steel and thicker steel. The nominal diameter is not a diameter, not diameter, but the approximate a diameter of ordinary steel pipe nominal size. Each of nominal diameter, corresponding to an outer diameter, the diameter values vary with thickness. Metric mm nominal diameter can be said, also available in English, said. Piping accessories is alsoexpressed with nominal diameter, meaning with tube.

     Nominal pressure: 2 (Nominal pressure), said the symbol PN, the maximum working pressure allowed when applied at a certain temperature. Control valve on the carbon steel body, to allow the maximum working pressure below 200 ℃ application; for iron body,to allow the maximum working pressure below 120 ℃ application;control valve on the stainless steel body, to allow the maximum working pressure below 250 ℃ application. When the t. When the temperature increases, the body of the pressure will be reduced.For example, the nominal pressure 6.4MPa (PN64) carbon steel for pressure control valve, 300 ℃ for 5.2MPa, 400 ℃ with a pressure of 4.1MPa, used for pressure at 450 ℃ for 2.9MPa. Therefore, to determine not only the nominal pressure control valve according to the maximum working pressure, also according to the maximum operating temperature and material characteristics, rather than simply meet the nominal pressure greater than the pressure of work.

    Soft sealing gate valve, valve industry, soft sealing gate valve is a gate opening and closing parts, RAM direction of motionperpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. There are two gate sealing surface, the most common mode of gate valvesealing surface to form two wedge, wedge angle varies with the valve parameters, usually 50, medium is not high temperature is 2 ° 52''''.

Belt guides

     The principle 

    Wedge gate valve can be made into a whole, called the steel gate;also be made to produce small deformation of the gate, in order to improve its process, make up the sealing surface angle deviationsarising during processing, this gate is called the flexible gate.

     Soft sealing gate valve into the next shot soft sealing gate valveand the dark bar soft sealing gate valve two. Usually in the lift rod with trapezoidal thread, through the guide groove of the middle of the nut and the valve body, the rotary motion into linear motion,which is the operating torque thrust into operation. Open the valve,when the gate valve lift height is equal to 1:1 times the diameter,the fluid flow channel completely, but at run time, this position is unable to monitor. 

     Actual use, is the apex of the stem as a symbol,which means that the fixed position, as its full open position.Temperature changes appear to consider locking phenomenon,usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position. Therefore, the fully open position of the valve, based on the location of gate (i.e. travel 'to determine. This type valve should normally be installed horizontally in the pipeline.
