Abstract
The utility model relates to a filling structure, and is suitable for a sealing system of control valves. The filling structure comprises an upper valve cover, a control valve rod, a gland flange, a lining, teflon rings, a filling lantern ring, a spring assembly and a spring body. The upper valve cover is hollow, both the upper valve cover and the gland flange are sleeved on the control valve rod, and the upper valve cover is connected with the gland flange. The lining, the filling lantern ring and the spring assembly are arranged between the control valve rod and the upper valve cover from bottom to top in sequence. The teflon rings are disposed between the lining and the filling lantern ring and between the filling lantern ring and the spring assembly, and the spring body is connected between the spring assembly and the gland flange. Compared with the prior art, the filling structure has the advantages of being good in sealing, low in cost, energy-saving, environmental friendly, convenient to maintain and the like.
Description
Technical field
The utility model relates to a kind of valve mechanism, especially relates to a kind of filling-material structure.
Background technique
The valve packing market of China is huge, and comparative maturity has asbestos packing, teflon braiding packing, rubber o-ring, a plastic shaping filler at present.But the sealability of filler and working life are also very low, and the filler of new structure is good seal performance not only, long service life, and the market prospects of this respect product are good, and the Development of Novel filling-material structure not only reduces the cost of product, more adapts to the low-carbon environment-friendly theory.
The model utility content
The purpose of this utility model is exactly to provide a kind of good seal performance, cost filling-material structure low, easy to maintenance for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
a kind of filling-material structure, be applicable to the sealing system of control valve, this structure comprises bonnet, control valve rod, gland flange, lining, polytetrafluoroethylene ring, the filler collar, spring assembly and spring body, described bonnet is hollow structure, described bonnet and gland flange all are set in to be controlled on valve rod, described bonnet is connected with gland flange, described lining, the filler collar and spring assembly are located at from top to bottom successively to be controlled between valve rod and bonnet, described polytetrafluoroethylene ring is located between lining and the filler collar and the filler collar and spring assembly, described spring body is connected between spring assembly and gland flange.
The two ends up and down of described polytetrafluoroethylene ring are equipped with liner.
Described polytetrafluoroethylene ring is V-ring.
The diameter of described polytetrafluoroethylene ring is greater than 1% of the hollow structure diameter of bonnet.This structure can not exert an influence to the installation and removal of filler.
Be connected by bolts and nuts between described bonnet and gland flange.
Filling-material structure of the present utility model is used for the sealing of rotary part between valve rod and valve body, stops flowing medium to leak with stem movement.Adopt this structure can reduce the axial stress of filler, thereby increase sealability, the working life of improving filler.
Compared with prior art, the utlity model has following advantage:
One, good seal performance: because the diameter that V-arrangement teflon annular groove is installed amplifies, reduced the axial stress of filler, thereby increased sealability.
Two, reduce costs: the working life of adopting this structure can improve filler, thus reduce the valve user cost.
Three, the theory of energy-conserving and environment-protective: the utility model filling-material structure can not produce surrounding environment and pollute, and meets the theory of energy-conserving and environment-protective, low-carbon (LC) life.
Four, easy to maintenance: because of simple in structure, component can be changed at any time, and it is convenient to repair.
