"Honeywell (Honeywell) Valve" is mainly used for stainless steel ball valve worm gear cut off or connected to the line of medium, can be used for fluid regulation and control, including the company's seal its V V-Ball type carbide ball and surfacing of the metal core between the valve seat has a strong shear force, especially for fibrous, tiny pieces of solid material and other media. The multi-way valve in the pipe can be flexibly controlled, not only the confluence of media, diversion, and flow switch, but also to turn off any channel leaving the other two channels connected. 

 The structural characteristics of ball 
 ① fluid resistance, ball valve in the fluid of all kind of least resistance, even reduced diameter valve, the fluid resistance is quite small. ② switch quickly and easily, as long as the stem turn 90o, Ball completed the open and close movement, it is easy to open and close fast. ③ valve seat seal. Most of the valve seals are used PTFE and other flexible materials, soft sealing structure is easy to ensure unsealed, and the valve sealing force increases with the increase of media pressure. ④ stem seal reliable. Valve open and close only when the stem rotates without movement at the valve stem packing seal is not easy damage, and seal down the valve stem sealing force increases with the increase of media pressure. ⑤ materials such as PTFE has good self-lubrication, the friction loss is small and the ball, so the ball long life. ⑥ configurable pneumatic, electric, hydraulic, and other drive mechanism to realize remote control and automation. ⑦ valve body channel is smooth and can transport viscous fluids, slurries and solid particles. ⑧ easy to install and can be installed in any direction to any location in the pipeline. 

 Products, the main structure, function 
 First, the clip series ball 
 Folder on the folder and the insulation jacket ball valve is our factory newly developed products, and general products, compared with the short length of the structure, light weight, easy installation, saving materials and other significant advantages. (Figure I, Figure II) 

 Second, the whole series and necking Path Series 
 My company has a full bore ball valve generally reduced diameter and two series, in order to meet the needs of different conditions. Full bore pipeline ball valves the channel diameter and the same diameter, the fluid path of least resistance, and to facilitate pipe cleaning. The necking is only the weight of the same series of ball valve full bore ball valve diameter about 70%, can effectively reduce the cost and price, while the fluid resistance is the same caliber valve only 1 / 7 or so, it reduced diameter ball valve abroad has been more widely used. Such as the right 
 Third, the reliability of the valve seat seal 
 1, the floating ball with double bevel or V-shaped elastic seal ring groove design flexibility. Effectively reduce the friction between the ball and the ring factor, reduce operating torque. When the medium pressure is small, ring and ball contact area smaller, so there is greater than the pressure seal to ensure a reliable seal. Medium pressure is high, ring and ball contact area increases, so the seals can withstand greater thrust without damaging the medium. (Right) 

 2, when the medium of the erosion force is larger, specially designed anti-valve seat structure can effectively prevent erosion scouring the media to ensure that the service life of seals. Such as (Figure D) 

 3, low pressure valve for the work, taking into account the medium pressure does not ensure a reliable seal the valve seat, while the preload will be attenuated after long-term use, so for low-voltage, ultra low-pressure or vacuum conditions with the ball, with spring plus contained in the seating structure, to ensure long-term reliable sealing valve. Such as (Figure E) 


 4, a fixed pressure valve according to the size of the sealing of different forms of choice: A: inlet seal B: the Sealing C: into, the exit-way seal. (See below) 

 As d1, d2 difference in the upstream area of the media pressure, the formation of the piston effect, so that the valve seat seal close contact with the ball. As d1, d2 in the area of difference in the body cavity of media pressure, the formation of the piston effect, so that the valve seat seal close contact with the ball. Since d1> d2> d3 on d1, d2, d3 difference between the area in the upper reaches of the media by the media and in the cavity under pressure to form the piston effect, so that the valve seat seal close contact with the ball. 

 Fourth, anti-static structure based on the user's requirements, the ball valve can be designed anti-static structure. A column by spring export plug-static devices, ie the ball and valve stem and the body set up between the conductive spring, the ball and the valve stem and the stem and the body formed between the static channel, to remove static electricity purposes. Avoid static electricity ignition ignite flammable media, to ensure system security. (Figure VII) 

 Fifth, a flexible operating mechanism open and close in a relative motion of parts (such as the stem and the body, stem and the packing pressure set), set the friction coefficient of PTFE bushings, not only reduces the operating torque , to open and more flexible, and avoid abrasion between the metal parts. Such as (Figure Eight) 
 Sixth, stem fly and the back seal erosion control structure 
 Download-type valve stem, set down with a sealing gasket sealing structure, sealed down with the media in the valve sealing force increases with increasing pressure to ensure that the valve stem seal. When an abnormal pressure chamber when the valve stem is not out, packed with well-designed V-type structure, the media can force the valve chamber, and external gland of the locking force into an effective force stem seals . Such as (Figure IX, Figure X) 

 Seven, fire resisting construction 
 According to the needs of users, the ball valve can be designed as fire-resistant structure. When leaving the event of a fire ring PTFE and other burning software, the ball is still able to operate reliably and with good sealing performance, in order to prevent the expansion of the fire. Such as (Figure XI) 


 VIII, automatic pressure relief valve structure when stranded in the liquid medium in the cavity temperature and gasification due to abnormal pressure in the chamber increases, the cavity can depend on the media to promote its own thrust and automatic pressure relief valve seat, thereby to ensure the safety of the body. Such as (Figure XII) 


 Nine, secondary seal structure according to the needs of users, the valve seat and stem sealing parts may raise fat valve position when the seal leakage caused by abrasion, through the valve into the grease seal blubber, can play instant seal. Such as (Figure XIII) 
 Ten, V-ball factory developed the V-type ball valve seal, the V-ball core and the metal carbide surfacing between the valve seat has a strong shear force, especially for fibrous, small solid particles, slurry and other media. (Figure XIV) 

 XI, the high temperature structure of the valve seat seal 
 Phenylene ring of bits used for the temperature of 300 ℃ high temperature composite materials sealed with full design of the valve can be used for higher temperatures. 
 Second, low temperature conditions to prevent the valve stem packing seal failure, low temperature valve design with a long neck. Use with automatic pressure relief valve seat design features to prevent the valve in the cavity medium as the emergence of abnormal heating step. Strict control of chemical composition and low temperature impact toughness and other mechanical properties.
