Description
Technical field
The utility model is related to valve technology field, especially a kind of monitoring shaft end seal performance is simultaneously realized to exempt to tear open and is remedied
Structure.
Background technology
Valve is mainly used for fluid control for controlling empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid
The flowing of the various types fluid such as state metal and radiating medium.Valve plays the work block, throttle, changing flow direction in pipeline
With.This requires valves must good sealing performance, avoids dielectric leakage.
As shown in Figure 1, existing most of sealing structure of shaft end are：End cap 5 is mounted on valve body 2, end cap and valve body it
Between install seal washer 3.Valve rod 1 is installed on valve body and end cap, and inner seal circle 4 and outside are installed between valve rod and end cap
Sealing ring 6.It is sealed for the moment though this traditional sealing structure of shaft end can meet, good solution is had no when finding leakage
Method may influence the normal operation of equipment.
Utility model content
The purpose of this utility model is that in place of making up the deficiencies in the prior art, providing one kind can find to seal in time
Circle failure and timely processing and do not influence equipment normal operation monitoring shaft end seal performance and realization exempt to tear the structure remedied open.
The purpose of this utility model is realized by following technological means：
A kind of monitoring shaft end seal performance simultaneously realizes and exempts to tear open the structure remedied, including end cap, valve body and valve rod, end cap peace
On valve body, seal washer is installed, valve rod is installed on valve body and end cap, between valve rod and end cap between end cap and valve body
Inner seal circle and outer side seal circle are installed, it is characterised in that：First passage is made on the inner ring surface of end cap, in the method for end cap
Second channel is made on blue face, first passage is connected with second channel；The tip designs of second channel are threaded hole, the screw thread
A silk plug is inserted in hole, silk plug sealing ring of the installation for shaft end seal on the madial wall of silk plug.
Moreover, the first passage is arranged between inner seal circle and outer side seal circle.
Moreover, the first passage is vertically arranged, cone-shaped, the lower end of first passage is made in the upper end of the first passage
It is connected with the second channel.
Moreover, the second channel is horizontally disposed, and second channel is blind hole.
Moreover, the silk plug is made of stainless steel.
Moreover, making third channel on the silk plug, which is L-type through-hole, and horizontal component is same with silk plug
Axis is arranged, and vertical portion is located at the interior front side of silk plug sealing ring.
The advantages of the utility model and good effect are：
1, the utility model is simple in structure, under the premise of ensureing original performance, by improving partial structurtes, realizes
It finds sealing ring failure in time and realizes in the case where not influencing equipment operation to be again sealed off, when Awaiting Overhaul phase replaces failure again
Sealing ring.
2, the utility model is simple in structure, can find that inner seal circle fails in time by the third channel on silk plug.
Silk plug is tightened when the failure of inner seal circle occurs and compresses silk plug sealing ring, forms new seal chamber so that outer side seal circle is sent out
The effect of waving, to realize shaft end seal again.
3, the utility model is a kind of monitoring shaft end simple in structure, easy to operation, can reducing influence equipment operation for some reason
Sealing performance and realize exempt to tear the structure remedied open.Seal failure position can be determined using this structure in time, and can be with by silk plug
In the case where not dismantling end cap, being again sealed off for shaft end is realized, to ensure the normal use of valve, when Awaiting Overhaul phase is right again
Sealing ring carries out repair and replacement.This structure design has ensured the operation steady in a long-term of equipment, reduces maintenance frequency, reduces dimension
Protect cost.
Description of the drawings
Fig. 1 is the original structure schematic diagram of shaft end seal；
Fig. 2 is the improved structural schematic diagram of shaft end seal；
Fig. 3 is the portions the A enlarged diagram of Fig. 2.
Specific implementation mode
Embodiment of the utility model will be described in detail below with reference to the attached drawings, it should be noted that the present embodiment is narrative
, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of monitoring shaft end seal performance is simultaneously realized and exempts to tear the structure remedied, including end cap 5, valve body 2, valve rod 1, silk plug 8 open
With silk plug sealing ring 7, end cap is mounted on valve body, and seal washer 3 is installed between end cap and valve body.Valve rod be installed on valve body and
On end cap, inner seal circle 4 and outer side seal circle 6 are installed between valve rod and end cap.
First passage 9 is made on the inner ring surface of end cap, which is arranged in inner seal circle and outer side seal circle
Between.First passage is vertically arranged, and cone-shaped (funnel-form), the lower end of first passage and second is made in the upper end of first passage
Channel is connected to.
Second channel is horizontally set on the flange face of end cap, which is blind hole, and the end of second channel is set
It is calculated as threaded hole.A silk plug is inserted in second channel, i.e.,：Silk plug and the threaded hole of second channel end are connected through a screw thread.
Silk plug uses stainless steel, prevents failure of getting rusty.Silk plug sealing ring of the installation for shaft end seal on the madial wall of silk plug.
Third channel is made on silk plug, which is L-type through-hole, and horizontal component is coaxially disposed with silk plug, is erected
Straight part is located at the interior front side of silk plug sealing ring.When silk plug and end cap are in loosening connection, second channel can be made to connect with extraneous
It is logical.
The operation principle of the utility model is：
In equipment normal operation, silk plug 8 is in loosen with end cap and connect, and is not required to form sealing.
When finding that shaft end there are media leaks, illustrate that inner seal circle 4 fails.Silk plug is tightened at this time and compresses silk plug sealing
Circle 7 forms new seal chamber and realizes shaft end seal.This structure can ensure the normal of valve in the case where being changed without sealing ring
It uses, repair and replacement is carried out to inner seal circle 4 again when the Awaiting Overhaul phase.
