Abstract
The utility model relates to a kind of flexible graphite sealing valve, it comprises valve body, flashboard, valve gap, be arranged on middle chewing-gum pad between valve gap and valve body and one end is connected with flashboard and runs through the valve rod of valve gap, the top of described valve gap is provided with stuffing box, described stuffing box inner chamber is provided with flexible graphite sealing cover, described stuffing box top is provided with gland, and the utility model has the reliable and advantage of long service life of easy for installation, high temperature resistant, sealingly secure.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of flexible graphite sealing valve.
Background technique
At present, existing valvular valve stem seal place is that particularly packing_seal is poor by the sealing such as packing, rubber seal ring, and installation is wasted time and energy, and easily reveals in using process, more non-refractory, and these seal life are short, uses a period of time to need to change.
Model utility content
For the problems referred to above, technical problem to be solved in the utility model is to provide the reliable and flexible graphite sealing valve of long service life of a kind of easy for installation, high temperature resistant, sealingly secure.
The utility model adopts following technological scheme:
The utility model comprises valve body, be arranged on the flashboard of body cavity, be arranged on the valve gap of valve body upper end, be arranged on middle chewing-gum pad between valve gap and valve body and one end is connected with flashboard and runs through the valve rod of valve gap, described valve gap upper end is provided with stuffing box, the inner chamber of described stuffing box is provided with flexible graphite sealing cover, described stuffing box upper end is provided with gland; Described valve rod upper end is provided with handwheel; Described flexible graphite sealing cover is sleeve-shaped; Be Spielpassung between described flexible graphite sealing cover and the inwall of stuffing box and between graphite grazing cover and the outer wall of valve rod, described stuffing box and gland are bolted.
Further, described stem surface is provided with chromium coating.
The utility model beneficial effect is as follows:
Flexible graphite sealing cover described in the utility model adopts the graphite paper of JB/T758.2-1995 to be rolled into paper web compressing sealing drum for similar axle sleeve like at high temperature under high pressure, the length of sealing drum and the thickness of barrel can as required sealed member need set.
(1) the utility model adopts flexible graphite sealing cylinder to seal, and this sealing heatproof is high, good sealing effect, it is time saving and energy saving to install, without the need to adding Expanded graphite separately between the spreadable life, flexible graphite sealing cylinder is comparatively smooth, comparatively flexible when smooth sealing drum makes hand wheel rotating.
(2) flexible graphite sealing cylinder has certain hardness, the packing made compared with asbestos rope or rubber seal not only wear-resisting, and its longitudinally to resist pressure energy power strong, a fastening a little lower cover just can seal very well upon wear.
(3) the utility model is Spielpassung because this employing flexible graphite sealing cylinder when adopting flexible graphite sealing cylinder to install is in contact with it parts, and install very convenient, a fastening a little lower cover will make valve rod seal completely after finishing assembly.
