Description
Technical field
The utility model relates to shut-off valve fields, and in particular to a kind of shut-off valve stuffing-box injecting glue plugging structure.
Background technique
Shut-off valve is also pipe valve, is a kind of most popular valve, and why very popular it is, is due to being opened and closed
Frictional force is small between sealing surface in journey, relatively durable, and Lift is little, manufacture be easy, it is easy to maintenance, be applicable not only in it is low
Pressure, and it is suitable for high pressure.The closure principle of shut-off valve is, by valve stem pressure, to keep valve clack sealing surface tight with sealing surface of seat
Closely connected conjunction prevents flow of media.
Shut-off valve has a wide range of applications in daily life and production, cuts frequent occurrence after shut-off valve is used for a long time
Only valve valve rod leakage accident, common valve rod leakage are blocked by the way of opening valve stuffing box, and in the feelings of No leakage
The premise that the mode of opening valve stuffing box is blocked under condition is that the back seal of shut-off valve is tightly effective, and still, structure is old
Or the poor shut-off valve of state often will appear the case where back seal failure, can only replace shut-off valve at this time, cause maintenance cost
Increase the waste with maintenance time.
Utility model content
The purpose of this utility model is to provide a kind of shut-off valve stuffing-box injecting glue plugging structures, to solve existing cut-off
Valve back seal can not leak the problem of repairing to valve rod in the case where failing.
To achieve the above object, the technical solution of the utility model is a kind of shut-off valve stuffing-box injecting glue plugging structure, packet
Valve body is included, valve stuffing box is provided with above the valve body, is filled with sealant, the valve stuffing box side in valve stuffing box
Injecting glue connector is provided on wall, the injecting glue connector is connected to inside valve stuffing box side side wall and valve stuffing box.
As advanced optimizing, the injecting glue connector includes injection part and interconnecting piece, the injection part and valve stuffing box
Connection, the interconnecting piece are set to injection part far from valve stuffing box one end.
As advanced optimizing, the interconnecting piece is internally provided with plugging block.
As advanced optimizing, the injection part uses metal material.
As advanced optimizing, the injecting glue connector is to be detachably connected with valve stuffing box side wall.
As advanced optimizing, the injecting glue connector is to be threadedly coupled with valve stuffing box side wall.
As advanced optimizing, when the valve of valve body opens to the maximum, table on the flap of the sealant and the valve body
Face paste is closed.
As advanced optimizing, the sealant is teflon rod by solidifying shape in high pressure injection valve stuffing box
At.
The utility model has the advantages that
1, when the back seal of shut-off valve can not work, sealant can be filled to avoid dismantling filler by injecting glue connector
Gland causes uncontrollable leakage, and the gap between valve rod and stuffing-box can be effectively blocked in injecting glue connector, avoids valve rod leakage.
2, when the valve of valve body opens to the maximum, sealant is bonded with the flap upper surface of the valve body to be guaranteed to seal
With best sealing effect while the journey that glue does not influence valve body uses.

Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
A kind of shut-off valve stuffing-box injecting glue plugging structure is provided with valve above valve body 1 in conjunction with Fig. 1 and Fig. 4, including valve body 1
Door stuffing-box 3, valve stuffing box 3 are connect by bolt with valve body 1, and 3 top of valve stuffing box is threaded with gland 33,
Stuffing-box cavity 31 (see Fig. 3) is constituted between valve stuffing box 3 and valve body 1, sealant 4 is filled in stuffing-box cavity 31, when
Sealant 4 is bonded with 11 upper surface of flap of valve body 1 when the valve of shut-off valve is opened to maximum, and sealant 4 is playing plugging effect
Prevent the valve rod 2 of shut-off valve from will not influence the normally-open closure function of shut-off valve while leakage.
In conjunction with Fig. 2 and Fig. 4, connecting hole 32 is offered on shut-off valve side wall, which is connected to stuffing-box cavity 31, even
It connects and is removably connected with injecting glue connector 5 in hole 32, the injecting glue connector 5 is through 3 side side wall of valve stuffing box and valve stuffing box 3
Inside connection.Injecting glue connector 5 includes injection part 51 and interconnecting piece 52, and injection part 51 is connect with valve stuffing box 3, and interconnecting piece 52 is set
Injection part 51 is placed in far from 3 one end of valve stuffing box, injection part 51 uses metal material, has good durability, by injecting glue
Machine is connect with interconnecting piece 52 can inject sealant 4 into stuffing-box cavity 31.Interconnecting piece 52 is internally provided with plugging block 53, the envelope
Sprue 53 can play the role of preventing the sealant 4 in injection stuffing-box cavity 31 from flowing back before solidification.
In conjunction with Fig. 4 and Fig. 5, injection part 51 is preferably threadedly coupled with the connection type of connecting hole 32, can prevent injecting glue connector 5
It is detached from valve stuffing box 3 during injecting glue, injecting glue connector 5 can also be removed after the completion of injecting glue and is blocked by silk plug 6
Operation.
Sealant 4 is formed using teflon rod by solidification in high pressure injection valve stuffing box 3, this kind of method is passed through
The sealant 4 of formation can avoid generating gap, keep plugging effect preferable.
The detailed process of sealant 4 are as follows: drilling and tapping on 3 side wall of valve stuffing box form connecting hole 32, by injecting glue
Connector 5 is fixed on 32 position of connecting hole, and valve is opened to maximum, and unclamps gland 333-5 circle, by glue-injection machine by injecting glue
5 high pressure of connector injects teflon rod, forms sealant 4, finally removes glue-injection machine and is connect by the closure injecting glue of plugging block 53
First 5, or remove injecting glue connector 5 and connecting hole 32 is blocked by silk plug 6.
Shut-off valve stuffing-box injecting glue plugging structure can be under the premise of not opening gland 33 to stuffing-box cavity 31
Interior injection sealant 4 avoids the occurrence of the leakage of valve rod 2, has easy to operate, and plugging effect is good, substitutes the shut-off valve that more renews
Method for maintaining to save maintenance cost the advantages that.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
