Description
Technical field
This utility model relates to a kind of import three-way valve gland system.
Background technology
Import three-way valve uses screw-tightened, and filling flavoring agent letter body is shallower, and fastening clamping torque is less, it is impossible to meet safety
, often there is the incident of leakage because fastening generation not in place in use demand.
Because above-mentioned defect, the design people's the most in addition research and innovation, to founding a kind of import three-way valve Glan
Sealing system so that it is have more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of sealing property that improve Glan.Subtract
Lack the import three-way valve gland system of the probability of leakage.
This utility model import three-way valve gland system includes that stuffing box body, described stuffing box body are provided with outer spiral shell
Stricture of vagina, described lower flange is set on described stuffing box body, and described lower flange is threadeded with described stuffing box body, described stuffing-box
The internal filler set that is provided with, filler set is pressed on sealed packing, and upper flange gland is pressed on described filler and puts, lower flange set
Fastened by 4 bolts with upper flange gland.
Further, lower flange set is carried out tightly by bolt and the nut of 8.8 grades of 4 M12 with upper flange gland
Gu.
Further, at upper flange gland, it is provided with sphere-contact.
Further, lower flange is connected to the gland threaded connection place of former import three-way valve gland structure, by 4
Bolt and the nut of 8.8 grades of M12 fasten.
By such scheme, this utility model at least has the advantage that
Change gland stud, use the bolt of greater degree material, add sealing intensity, improve sealing force,
Sealing effectiveness strengthens.
Equipment self-position type puts the design of sideslip sphere-contact, prevents fastened offset, it is to avoid leaking outside of high-temperature steam occur.
Ensure equipment safety operation, improve the utilization rate of equipment.
Transformation does not affect the operation of existing equipment.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright as after.
Accompanying drawing explanation
Fig. 1 is the structural representation of lower flange of the present utility model；
Fig. 2 is the sectional view of Fig. 1；
Fig. 3 is the structural representation of upper flange plate of the present utility model；
Fig. 4 is the sectional view of Fig. 3.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
See Fig. 1 to Fig. 4, the present embodiment import three-way valve gland system, including stuffing box body, described stuffing box body
Being provided with external screw thread, described lower flange is set on described stuffing box body, and described lower flange is threadeded with described stuffing box body,
Being provided with filler set in described stuffing box body, filler set is pressed on sealed packing, and upper flange gland is pressed on described filler set
On, lower flange set is fastened by 4 bolts with upper flange gland.Lower flange set and upper flange gland are by 4 M12
The bolt of 8.8 grades and nut fasten.It is provided with sphere-contact at upper flange gland.Lower flange be connected to former enter
The gland threaded connection place of mouth three-way valve gland structure, bolt and nut by 8.8 grades of 4 M12 fasten.
Arranging ring flange symmetrical above and below and connect stretching, lower flange is connected to former gland threaded connection place, by 4 M12's
Bolt and the nut of 8.8 grades fasten.Increasing filler set, the bolt presses becoming 4 original M6 is the whole circle pressurization of filler set.
For preventing filler from overlapping sideslip, at upper press cover, it is provided with sphere-contact, enables gland force balance.
Height add three-way valve outlet Glan valve on main feed water pipe road, main feed pressure 28MPa, temperature 273 DEG C, valve is in
Opening, gland is preferable, does not occurs that leakage situation occurs, and running status is optimal.Valve is after multiple switching, and master gives
Water pressure 28MPa, temperature 273 DEG C, tightly there is not the situation of leakage in Glan face seal, and running status is optimal.
This utility model improves the fastening procedure of import three-way valve Glan, and the installation having adapted to domestic maintainer is thought
Road, it is possible to make enough fastening forces when three-way valve Glan filler installs additional.After the strength check carrying out bolt, transform Glan
It is feasible for sealing structure, improves the sealing property of Glan.Decrease the probability of leakage.
This utility model changes gland stud, uses the bolt of greater degree material, adds sealing intensity, improves
Sealing force, sealing effectiveness strengthens.
Equipment self-position type puts the design of sideslip sphere-contact, prevents fastened offset, it is to avoid leaking outside of high-temperature steam occur.
Ensure equipment safety operation, improve the utilization rate of equipment.
Transformation does not affect the operation of existing equipment.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, it is also possible to do
Going out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
