A kind of valve buttress of fluid pressure type adjustable lifting
Technical field
The technical field of the apparatus buttress devices such as natural gas transportation, site technique equipment is the utility model is related to, is especially related to
A kind of and valve buttress of fluid pressure type adjustable lifting.
Background technology
All there is sink or because under caused by geological conditions reason all in running status, foundation for valve and equipment
Sink, what we can do at present is exactly simple reinforcing and processing, can only simple in finding out for effort, permanent effective, easy care
Method.The reasons such as this designs existing defects easy-to-rust, generation regulation has some setbacks.Regular maintenance is such as carried out, avoids the originals such as corrosion
Cause, the generation that problems will be reduced.
In gas pipeline system, pipeline junction can largely use the valve of each model, generally used
Valve volume is big, weight weight, and the pressure of the cement buttress below valve is larger, and ground may below valve in running
There is sedimentation phenomenon, cause many pipelines and valve to be in vacant state, or deform upon pipeline junction, cause natural gas
Leakage, has a strong impact on safe for operation.
Utility model content
The utility model supplies a kind of simple in construction, carry an object to be provided the defects of overcoming above-mentioned prior art to exist
Conveniently and it can be adapted to install with a kind of automatically reset valve buttress of fluid pressure type adjustable lifting, its liftable regulatory function
There is the antistatic floor room under different height, taken into account and anti-stumbled, evacuate and can also effective protection staff even if personnel's touching
The function of touch position, reduce bump injury.
The technical scheme that the utility model solves above-mentioned technical problem is as follows:A kind of valve branch of fluid pressure type adjustable lifting
Pier, the valve buttress are horizontally set on bottom plate, and the valve top for carrying valve is provided with the top of the valve buttress
Plate, the valve buttress pack at least three groups of elevating mechanisms, and the elevating mechanism includes screw rod and profile nut, the special-shaped spiral shell
Mother, which is connected through a screw thread, to be set on the screw rod, and the profile nut, can be relative to screw rod axial direction in the case where external force turns
It is mobile;Screw vent is provided with the valve top plate, the upper end of the screw rod, which passes the screw vent, makes the valve top
The bottom of plate is overlapped on the upper end of the profile nut, and the lower end of the screw rod is arranged on the bottom plate;In the bottom plate
The upper center between the elevating mechanism is additionally provided with the hydraulic lift for carrying the valve top plate.It is logical
Cross height of the relation in a small range adjustment valve top plate of threaded connection, prevent because valve vacantly caused by valve connection it is unexpected
The generation of accident, suitable for the faint difference in height caused by ground settlement between valve buttress and valve, and combine valve
Actual conditions, while hydraulic lift (such as hydraulic jack) is installed in larger buttress, it easily can freely raise valve
Top plate, then the regulation of profile nut, screw rod is carried out, reach the purpose of support, so as to ensure the stability of process equipment and safety
Property.Change with pretreatment mode, improve service efficiency and durability, the maintenance frequency of less live buttress, effective improve sets
It is standby to stablize machine security, make device rest pier often occur in Gas Stations, valve chamber to sink to being improved.
Further:A rolling bearing is embedded with the screw vent, the outer ring of the rolling bearing, which is fixed, is located at institute
State in screw vent, the upper end of the profile nut is provided with round ring boss, and the inner ring of the rolling bearing is set in described
On round ring boss.Rolling bearing is set, prevents from causing the frictional force because of profile nut and valve top plate because of rotating special-shaped nut
And valve top plate is affected, improve the firm characteristic of valve buttress.
Further:Spirit level is provided with the valve top plate.Spirit level is set to be used for monitoring the adjustment of rotating special-shaped nut
During the height of valve top plate, whether valve top plate is horizontal, directly can should rotate which orientation adjusted according to spirit level analysis
Profile nut, operation are more convenient, accurate.
Further:Screw rod sheath is arranged with outside the lower end of the screw rod, the lower end of the screw rod sheath is fixedly installed on institute
State on bottom plate, the profile nut can be moved downward to the upper end for being connected to the screw rod sheath in the case where external force turns.Spiral shell is set
Bar sheath carries profile nut, prevents that caused valve top plate, which tilts, causes valve because unexpected stress causes profile nut stripped thread
Fixed carrying goes wrong.Now the other end of screw rod can go directly on bottom plate, or be set in screw rod sheath by profile nut
Interior, such a design can carry the larger valve of difference in height, carrying height for recoil inserts height to recoil inserts and spiral shell
Bar height sum, use range are wider.
Further:The screw rod sheath is circular tube shaped, and the upper end of the screw rod sheath is movably set under the screw rod
End is outer, and the lower end of the screw rod sheath is provided with square boss, and square groove is provided with the bottom plate, and the square boss is consolidated
Surely it is embedded in the square groove.Screw rod sheath is connected on bottom plate by the square boss and square groove of matching, prevented
Only because rotating special-shaped nut causes, because driving rotary screw sheath the frictional force of profile nut or screw rod and screw rod sheath, to carry
The firm characteristic of high valve buttress.
Further:The material of the screw rod, profile nut and screw rod sheath is stainless steel.Stainless steel is not likely to produce burn into
Spot corrosion, corrosion or abrasion.Because stainless steel has good corrosion resistance, but also collect mechanical strength and deep drawing quality in one
Body, it is easy to the processing and manufacturing of part, meets the design requirement of elevating mechanism, service life is longer.
Based on above-mentioned technical proposal, the beneficial effects of the utility model are:It the utility model is related to natural gas transportation, scene
The technical field of the apparatus buttress device such as process equipment, a kind of valve buttress of fluid pressure type adjustable lifting, valve buttress are arranged on
On bottom plate, valve top plate is provided with the top of valve buttress, valve buttress packaging at least three groups of elevating mechanisms, elevating mechanism includes
Screw rod and profile nut, profile nut, which is connected through a screw thread, to be set on the screw rod, and profile nut, can phase in the case where external force turns
Moved axially for screw rod;Screw vent is provided with valve top plate, screw rod upper end, which passes screw vent, makes the bottom of valve top plate
End is overlapped on profile nut, and screw rod lower end is arranged on bottom plate;Center on bottom plate between elevating mechanism is also
It is provided with hydraulic lift.The relation being connected through a screw thread adjusts the height of valve top plate in a small range, prevents because of valve
The generation of valve connection contingency caused by hanging, suitable for micro- between valve buttress and valve caused by ground settlement
Weak difference in height, and the actual conditions of valve are combined, while hydraulic lift (such as hydraulic jack is installed in larger buttress
Top), valve top plate easily can be freely raised, then the regulation of profile nut, screw rod is carried out, reach the purpose of support, so as to ensure
The stability and security of process equipment.Change with pretreatment mode, improve service efficiency and durability, less live buttress
Maintenance frequency, it is effective to improve the stable machine security of equipment, make device rest pier often occur in Gas Stations, valve chamber to sink to obtain
It is certain to improve.
