Description
Technical field
The utility model relates to valve fields, more particularly to a kind of safety valve regulator.
Background technique
In safety valve assembling process, need multiple debugging, the spring of some heavy caliber high pressure safety valves have precompressed and
Rigidity is big, and traditional pressure regulation method implements or relative difficulty, time-consuming and laborious or with certain defective, is easy
Cause the damage of part.There are mainly two types of pressure regulation method at present:
Directly rotate adjustment screw using spanner: this method be valve (heavy caliber, high pressure) after the assembly is completed, two to three
People's resultant force uses spanner and extension bar to rotate adjustment screw, plays adjustment valve release pressure by adjusting screw rod scaling spring
Effect.This method is not only time-consuming and laborious, can only assemble within one day a heavy caliber safety valve, and be prone to wear adjustment screw and bullet
Spring abutment, this virtually causes the increase of production cost, the decline of production efficiency.
Use hydraulic jack stretch valve rod: this method be valve after the assembly is completed, use hydraulic tool stretch safely
The valve rod of valve eliminates the spring force between adjustment screw and valve deck by the mobile compressed spring of valve rod.Then it is rotated by spanner
Adjustment screw is rotated together with parts such as ovable valve stem, spring, flap, flap seats to adjust the release pressure of valve, and adjustment is completed
Discharge valve rod return again afterwards.This method is although laborsaving, but when stretching valve rod, flap, flap seat are and then raised together, and valve
Valve may be with movement when valve rod difference (there are frictional force between flap and flap seat, and pressure and contact surface are all very big), rotation
When be easy to cause screw thread between valve rod and flap stuck, part of damage causes the failure of part and valve performance；And poppet stem
Process, it has not been convenient to judge whether flap lifts off a seat completely, when rotation may damage sealing surface.
Therefore a kind of release pressure of completely new, more reasonable, safe hydraulic device adjustment valve need to be designed to avoid
State problem.
Summary of the invention
The purpose of the utility model is to provide a kind of safety valve regulators, carry out on the basis of existing regulator
Improvement innovation, not only avoids the stuck problem of the screw thread between valve rod and flap, but also pressure regulation is more intuitive, conveniently.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of safety valve regulator, comprising:
Pressing sleeve offers the first overlap aperture, and the maximum width of the pressing sleeve or outer diameter are less than safety valve and adjust screw thread
The internal diameter of bar；
Jack offers the second overlap aperture；
Fixing sleeve offers third overlap aperture, and the fixation for mutually fixing with valve rod is provided on the fixing sleeve
Portion,
When connection: pressing sleeve, jack and the fixing sleeve is set gradually from lower to upper, the jack lower part with
The pressing sleeve top offsets, and the lower part of the fixing sleeve and the top of the jack offset.
Preferably, the jack is hydraulic jack.
Preferably, the piston body that the jack has cylinder body, matches with the cylinder body, the cylinder body, work
Cock body encloses oil pocket, and the piston body lower part offsets with the pressing sleeve top, and the cylinder body top is consolidated with described
Surely the lower part covered offsets, and when injecting hydraulic oil into the oil pocket, the cylinder body, piston body are relatively distant from.
It is further preferred that offering the entry/exit oil channel being connected with oil pocket on the piston body.
Preferably, the fixed part is the internal screw thread being provided in the third overlap aperture.
Preferably, the regulator further includes the pedestal for placing safety valve.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
1, all the type safety valves can be covered by adaptation pressing sleeve and fixing sleeve；
2, when pressure regulation, adjustment one part of threaded rod need to be only rotated, it is more acurrate, intuitive；
3, when pressure regulation, the part in cavity does not follow a possibility that rotating, reducing damage parts, guarantees the reliable of valve
Property；
4, working efficiency is improved, reduces the probability that worker makes a mistake, therefore reduce production cost.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
A kind of safety valve regulator as shown in Figure 1, comprising:
Pressing sleeve 1 offers the first overlap aperture 10, and the maximum width of pressing sleeve 1 or outer diameter are less than safety valve and adjust threaded rod 7
Internal diameter, in the present embodiment: pressing sleeve 1 is equivalent to lantern ring.
Jack 2 offers the second overlap aperture 20.In the present embodiment: jack uses hydraulic jack.It is specifically tied
Structure are as follows: the piston body 22 that jack 2 has cylinder body 21, matches with cylinder body 21, cylinder body 21, piston body 22 enclose oil pocket 23,
The entry/exit oil channel 220 being connected with oil pocket 23 is offered on piston body 22.When injecting hydraulic oil into oil pocket 23, cylinder body
21, piston body 22 is relatively distant from；When extracting hydraulic oil out out of oil pocket 23, cylinder body 21, piston body 22 are relatively close.
Fixing sleeve 3 offers third overlap aperture 30, and is provided on fixing sleeve 3 for the fixation fixed with 9 phase of valve rod
Portion, in the present embodiment: fixed part is the internal screw thread 31 being provided in third overlap aperture 30.
Pedestal 4, for fixing safety valve.
The working principle of lower the present embodiment is illustrated in detail below:
Pressing sleeve 1: being set on valve rod 9 by installation regulator first, and is pressed on adjustment guide rod 7, then by jack 2
It is set on valve rod 9, and is pressed on pressing sleeve 1, finally fixing sleeve 3 is set on valve rod 9, and be pressed on jack 2, by interior
Fixing sleeve 3 and valve rod 9 are fixed screw thread 31, as shown in Figure 2；
Jack 2 works, compressed spring 8: hydraulic oil drives pressing sleeve by compressing the piston body 22 of jack 2 downwards
1, guide rod 6, the downward compressed spring 8 of spring base 50 are adjusted；Meanwhile jack 2 has fixing sleeve 3 to valve rod 9 by cylinder body 21
One upward power, valve rod 9 pass through the upward compressed spring 8 of spring base 51；Spring force is finally equilibrated at serial number valve rod 9 and adjustment
Between guide rod 6；
Finally, making to adjust guide rod 6 and adjusting screw thread by the gravity of the parts such as spring 8, valve rod 9, spring base 50,51
Bar 7 is separated by a distance, as shown in Figure 3；
Pressure regulation: since adjustment guide rod 6 and adjustment threaded rod 7 are separated by a distance, adjustment threaded rod 7 is just not subjected to bullet
Spring force, at this moment using spanner rotation adjustment threaded rod 7 to certain position pressure regulation with regard to very comfortable, the position of adjustment is also very straight
It sees, is accurate；
It resets: after adjustment 7 position of threaded rod mixes up, discharging jack 2, make to adjust guide rod 6 and adjust 7 lower section of threaded rod
It is contacted again, pressure regulation is completed.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
