Description
Technical field
The utility model relates to safety valve field, particularly relates to pressure adjustable pressure-adjustable safety in a kind of certain limit
Valve.
Background technology
Safety valve is that opening and closing element is in normally off by under external force effect, when the pressure medium in equipment or pipeline rises superb
When crossing setting, in preventing pipeline or equipment by discharge medium outside system, pressure medium exceedes specified value.Safety valve
Belonging to automatic valve class, being mainly used in boiler, on pressure vessels and pipes, control pressure is less than setting, to personal safety and
Equipment has run important protective effect.With the fast development of China's economic construction, in the items of equipment work with pressure management
Journey gets more and more.In view of the needs of equipment pressure release, safety valve plays vital effect in protection device procedures.
In some specific occasion, the environment that uses of safety valve is not invariable, beating of different demand safety valves
Opening pressure different, it is desirable to safety valve pressure adjustable in certain scope, the safety valve of prior art can not meet this and require.
Content of the invention
The purpose of this utility model is not enough for overcoming present in background technology, and the purpose of this utility model is to propose one
The graduated adjustable pressure safety value of the adjustable band of pressure in certain limit.
For reaching above-mentioned purpose, the utility model uses following scheme: adjustable pressure safety value, including valve body, sealing gasket, close
Envelope seat, spring, adjustment cap, pad, spring base, regulation screw, O-ring, fixing screw, fluid sealant；Described valve inner hollow,
Being provided with an import, an outlet on valve body, valve body is provided above a valve seat in import, and valve seat is provided above sealing
Pad and seal receptacle, sealing gasket and seal receptacle are connected fixing by fixing screw, and described adjustment cap is arranged on the top of valve body, regulation
It is threaded connection between cap and valve body；Described spring is arranged between seal receptacle and adjustment cap, and described spring is provided above
Spring base, described regulation screw is arranged on the top of spring base, threadeds between regulation screw and adjustment cap；Described adjustment cap
And it is provided with pad and O-ring between valve body, by inwardly riveting fixing to valve body upper end, to adjustment cap extreme higher position
Carry out spacing, and guarantee the sealing between valve body and adjustment cap.Having multiple scale in described adjustment cap, each scale is corresponding different
Safety valve open pressure；Regulation screw top is provided with fluid sealant, it is ensured that the sealing between regulation screw and adjustment cap.
The utility model initial pressure set: after Product Assembly completes, minimum pressure graduation mark and the valve of adjustment cap
Aliging in body upper end, turns regulation screw, makes the pressure of opening of safety valve keep consistent with the scale value in adjustment cap, in regulation
Place fluid sealant on screw, prevent from regulating screw loosening.
Operation principle of the present utility model: after pressure exceedes setting value, under the use of pressure, makes spring-compressed, close
Move on packing, depart from valve seat, entrance sleeve is connected with discharge connection, it is achieved pressure release；Press when dropping below system work
During predetermined value (i.e. the closing presure) of power, under spring force, valve closing, keeps sealing；When pressure is opened in needs regulation
During power, turning adjustment cap, what different scale correspondences was different opens pressure.
After using technique scheme, the utility model has the advantage that by turning adjustment cap, can adjust safety
Valve difference opens pressure corresponding spring pre-tightening height；It is provided with scale, corresponding different the opening of different scales in adjustment cap
Pressure, product structure is simple, and user is easy to use.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of adjustment cap described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As it can be seen, adjustable pressure safety value, including valve body the 1st, sealing gasket the 2nd, seal receptacle the 3rd, spring the 4th, adjustment cap the 5th, pad is the 6th,
Spring base the 7th, regulate screw the 8th, O-ring the 9th, fix screw the 10th, fluid sealant 11；Described valve body 1 inner hollow, valve body 1 is provided with
One import the 12nd, outlet 13, valve body 1 is provided above a valve seat 14 in import 11, and valve seat 14 is provided above sealing
Pad 2 and seal receptacle 3, sealing gasket 2 and seal receptacle 3 are connected fixing by fixing screw 10, and described adjustment cap 5 is arranged on valve body 1
Top, is threaded connection between adjustment cap 5 and valve body 1；Described spring 4 is arranged between seal receptacle 3 and adjustment cap 5, described
Spring 4 is provided above spring base 7, and described regulation screw 8 is arranged on the top of spring base 7, regulation screw 8 and adjustment cap 5 it
Between threaded；It is provided with pad 6 and O-ring 9, by riveting inside to valve body 1 upper end between described adjustment cap 5 and valve body 1
Connect fixing, adjustment cap 5 extreme higher position is carried out spacing, and guarantees the sealing between valve body 1 and adjustment cap 5；In described adjustment cap 5
Having multiple scale, pressure opened by the corresponding different safety valve of each scale；Regulation screw 8 top is provided with fluid sealant 11, it is ensured that
Sealing between regulation screw 8 and adjustment cap 5.
The utility model initial pressure set: after Product Assembly completes, minimum pressure graduation mark and the valve of adjustment cap 5
Aliging in body 1 upper end, turns regulation screw 8, makes the pressure of opening of safety valve keep consistent with the scale value in adjustment cap 5,
Place fluid sealant 11 on regulation screw 8, prevent regulation screw 8 from loosening.
Operation principle of the present utility model: after pressure exceedes setting value, under the use of pressure, makes spring 4 compress, close
Move on packing 2, depart from valve seat 14, inlet and outlet is connected, it is achieved pressure release；When dropping below the pre-of system working pressure
During definite value (i.e. closing presure), under spring force, valve closing, keeps sealing；When pressure is opened in needs regulation, twist
Dynamic adjustment cap, what different scale correspondences was different opens pressure.
After using technique scheme, the utility model has the advantage that by turning adjustment cap, can adjust safety
Valve difference opens pressure corresponding spring pre-tightening height；It is provided with scale, corresponding different the opening of different scales in adjustment cap
Pressure, product structure is simple, and user is easy to use.
