Specific implementation mode
As shown in Figure 1, a kind of super high pressure fluid safety valve, including valve body 1, it is located in valve body 1 and is tightly connected with valve body 1
Valve seat 2, valve rod 3 is bolted with outside valve body 1, elastic component 4 is equipped in valve rod 3, is equipped in valve body 1 and valve body 1 is tightly connected and energy
The guiding axis 5 moved axially back and forth along valve body 1, guiding axis 5 is between elastic component 4 and valve seat 2, in guiding axis 5 close to valve
One end of seat 2 is set there are one sealing chuck 6 in a ring, and sealing chuck 6, which snaps onto, to be connect in valve seat 2 with valve base sealing, is oriented to
Flow increasing chamber 7 is formed between 2 top of 5 bottom of axis and valve seat and the flow increasing chamber 7 is around sealing chuck 6, is equipped on valve body 1 and is run through valve
The deflector hole 8 of body 1.
In the present embodiment, it is tightly connected and sealing ring connection can be used, the mode of sealing is the prior art, no longer superfluous herein
It states.
After pressure end superpressure, liquid-driving with pressure seals chuck 6, and fluid enters flow increasing chamber 7, when fluid fills up flow increasing chamber
Afterwards, to the active area of sealing chuck 6 before pressurized fluid is far longer than the active area of guiding axis, so can push rapidly
Guiding axis acts, and end pressure just can be released stress after flow increasing chamber 7 is connected to deflector hole 8, when stream pressure is to the active force of guiding axis
With elastic component for the force balance of guiding axis after, between guiding axis and deflector hole formed a stable leakage rate, at this time
Fluid end superpressure hydraulic pressure value before maintaining the hydraulic pressure value for being oriented to spindle balance to be far smaller than, pressure end obtain continuing pressure release, effectively
It ensure that the safety of system.
Elastic component 4 includes disc spring, and being spirally connected in valve rod 3, there are one look nuts 15, and 4 both ends of elastic component are pushed up respectively
Tight guiding axis 5 and look nut 15.End cap 101 there are one being set at the top of valve rod 3, for blocking look nut 15, body base spiral shell
It is connected to connecting rod 100, connecting rod 100 is convenient for and pressure relief equipment is attached.
A buffering ring 9 is arranged with outside valve body 1, buffering ring 9 is located at 8 outside of deflector hole and position is corresponding with deflector hole 8.It is slow
Rushing the design of ring makes high-pressure fluid pass through when deflector hole ejects first to be injected on buffering ring, just can discharge exhausted big portion in this way
The pressure divided avoids security risk caused by possibility.3. two relief grooves are devised on guiding axis, after seal fails,
The fluid of leakage can discharge certain pressure when passing through relief groove, impact part after avoiding fluid leakage, make zero impacted
Part damages.
Steel ball 10 there are one being set in sealing chuck 6 eliminates complicated valve head processing work using steel ball as valve head
Skill, steel ball is as standard component, and there are many specification, type selecting is convenient, price economy material benefit, and ball face sealing is relatively reliable.Described
Guiding axis 5 is equipped with relief groove 11, and valve seat 2 is equipped with pressure release runner 12, and steel ball 10 is pressed on pressure release runner 12.
It will be appreciated by those skilled in the art that in design, steel ball 10 and shape, the size of sealing chuck 6 match, when
When sealing chuck 6 with the clamping of valve seat 2, steel ball blocks the outlet of pressure release runner 12 just.Therefore, it when steel ball moves upwards, lets out
Pressure runner 12 is opened.
Preferred embodiment, there are two relief grooves 11, and each relief groove is along the circumferentially disposed of guiding axis.After seal fails,
The fluid of leakage can discharge certain pressure when passing through relief groove, impact part after avoiding fluid leakage, make zero impacted
Part damages.
Valve body 1 is equipped with the first leak holes 13 close to one end of valve seat 2, and valve rod 3 is let out close to one end of guiding axis 5 equipped with second
Reveal hole 14, first leak holes 13 and the second leak holes 14 extend through valve body 1 and valve rod 3.
When corresponding first leak holes or the second leak holes start to leak, can effectively judge corresponding close in safety valve
Sealing is no longer valid, removes complicated checking process from.
First leak holes 13 are connected to the gap between valve seat 2 and valve body 1, and the second leak holes 14 are connected to guiding axis 5 and valve rod 3
Between gap.
Deflector hole 8 is in be obliquely installed from top to bottom to outside by 1 inside of valve body.
First leak holes 13 are in be obliquely installed from the bottom up to outside by 1 inside of valve body.
In conjunction with shown in Fig. 2, the one end of look nut 15 far from elastic component 4 sets that there are two the ear slots that are located along the same line
16.The design of ear slot 16 makes look nut 1 that need to be rotated with specific purpose tool, prevents the setting pressure of layman's regulation safety valve
Value.The design of ears slot enables look nut to bear prodigious torque with specific purpose tool on look nut.
The operation principle of the utility model is：
After fluid end superpressure, band press liquid can push steel ball 10 to be detached from valve seat 2.After steel ball is opened, fluid with pressure
The space between valve seat 2 and guiding axis 5 can be entered, namely entered in flow increasing chamber 7, after fluid is full of flow increasing chamber 7, flowed at this time
Body pressure is still to push the pressure value of steel ball action, however pressurized fluid is right before being far longer than to the active area of guiding axis
The active area of steel ball makes guiding be moved axially away from the direction of valve seat so guiding axis can be pushed to act rapidly.It is close when before
The space closed be connected to the deflector hole 8 on valve body 1 after at this time safety valve just can release stress end pressure.When stream pressure is to guiding axis
After active force and elastic component 4 are for the force balance of guiding axis, a stable leakage is formed between guiding axis and deflector hole
Amount, there is fluid end superpressure hydraulic pressure value to keep stablizing pressure release before maintaining the hydraulic pressure value for being oriented to spindle balance to be far smaller than at this time
The safety that ensure that system of effect.After pressure end pressure is less than the pressure of elastic component, 5 return of guiding axis, steel ball blocks pressure release
Runner 12.
