Abstract
A kind of oil immersed type filling seal valve.The purpose of this utility model is that design is a kind of rational in infrastructure, the oil immersed type filling seal valve that using effect is good.The technical solution of the utility model is, a kind of oil immersed type filling seal valve, it comprises valve oil storage slot type Gland, pressure spring, oil storage slot type Gland is installed on top, valve packing room, oil storage slot type Gland is sleeved on valve rod, is set with pressure spring in oil storage slot type Gland, and oil storage slot type Gland top is provided with upper press cover, described upper press cover bolt is fixedly mounted on valve body, and the bottom of oil storage slot type Gland contacts with filler.The utility model is rational in infrastructure, and using effect is good, effectively raises the sealing effect of valve packing, extends the working life of valve packing and valve rod, reduces air-loss, solves because valve packing reveals the environmental protection and potential safety hazard caused.
Description
Technical field:
The utility model relates to valve, particularly the better oil immersed type filling seal valve of a kind of sealing effect.
Background technique:
In the coal gas workshop section of Chemical Manufacture, valve operation conditions is comparatively severe, and valve packing is by the impact of high temperature, dust, gaseous impurity etc., and working life is short, safeguards and changes frequently.After valve runs, valve packing, due to by the axial motion of valve rod and the impact of temperature, causes filler axial clearance to increase, and filler radial sealing force reduces, and very easily produces filler leakage problem; Simultaneously because coal gas is poisonous, inflammable, once occur revealing, will produce combustible source, directly affect safety in production, the toxic gas of leakage pollutes the environment, and very easily causes personnel's intoxicating phenomenon, affects employee healthy.And after valve packing seal failure, the leakage of coal gas also can cause consumption high, directly affects cost of production.
Summary of the invention:
The purpose of this utility model is that design is a kind of rational in infrastructure, the oil immersed type filling seal valve that using effect is good.
The technical solution of the utility model is, a kind of oil immersed type filling seal valve, it comprises valve oil storage slot type Gland, pressure spring, it is characterized in that: oil storage slot type Gland is installed on top, valve packing room, oil storage slot type Gland is sleeved on valve rod, is set with pressure spring in oil storage slot type Gland, and oil storage slot type Gland top is provided with upper press cover, described upper press cover bolt is fixedly mounted on valve body, and the bottom of oil storage slot type Gland contacts with filler.
The utility model is rational in infrastructure, and using effect is good, effectively raises the sealing effect of valve packing, extends the working life of valve packing and valve rod, reduces air-loss, solves because valve packing reveals the environmental protection and potential safety hazard caused.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe embodiment in detail by reference to the accompanying drawings, specific embodiment of the utility model is, a kind of oil immersed type filling seal valve, it comprises valve oil storage slot type Gland 5, pressure spring 4, oil storage slot type Gland is installed on top, valve packing room 7, the part that valve rod 1 is close in valve packing indoor is filled with filler 6, oil storage slot type Gland is sleeved on valve rod, pressure spring is set with in oil storage slot type Gland, oil storage slot type Gland top is provided with upper press cover 3, described upper press cover bolt 2 is fixedly mounted on valve body 8, the bottom of oil storage slot type Gland contacts with filler.The utility model bolt is by upper press cover, oil storage slot type Gland, pressure spring and valve body are fixing after compressing, because stem shaft compensates to running the axial clearance produced after the self-aligning action that such the utility model make use of pressure spring puts into operation to valve packing.After valve runs, valve packing is owing to being subject to the axial motion of valve rod and the impact of temperature, filler axial clearance is caused to increase, filler radial sealing force reduces, under the compensatory pressure effect of pressure spring, can effectively to gap and reinforcing filler radial sealing force, packing seal effect be protected by adjustable axle.Lubricant oil in oil storage slot type Gland lubricates valve rod and filler, lower the temperature while, effectively avoid the impact of introduced contaminants and dust, decrease valve be in operation produce wearing and tearing and cause seal failure, improve sealing effect and the working life of filler.
