Description
Technical field
A kind of safety valve class technical field is the utility model is related to, especially a kind of new safety valve.
Background technology
Safety valve is the safety device of pressure piping, is typically mounted on closed system equipment or pipeline and protects system
System safety, when the pressure inside the equipment of closed system or pipeline exceedes setting value, safety valve automatically turns on release pressure,
Ensure that the pressure medium in equipment or in pipeline in specified value, prevents security incident, however, common safety valve
Sealing generally uses end cap sealing ring under spool, with plane gluing, sealing, valve in the plane of sealing ring and the exhalant canal of valve body
The upper end shock mount of core, similar structure have following drawback：The complicated of one, spools, shape are larger, and spillage of material is high；Two,
Spool is simply simple stacked with spring, and spring easily shifts at work so that the thrust that spring provides reduces, further
Causing the leakproofness of safety valve to reduce, the security risk of leakage also greatly improves,
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of new safety valve, including
Valve body, valve rod, spool, trapezoidal spring, spring bonnet, valve seat, fixing nut, adjusting screw, the passage of the inner cavity lower end of valve body
Suitable for reading to set circular arc sealing surface, valve rod lower end sets spool, upper end sets adjusting screw, and spool lower end sets sphere, and sphere is sealed with circular arc
Face radian is consistent, and trapezoidal spring pocket is outside valve rod, and trapezoidal lower spring end props up the upper surface of spool, upper end props up spring bonnet
It is fixed after adjusting screw stretches out the upper end of spring bonnet from inside to outside after the internal thread of inner face, spring bonnet and valve seat is spirally connected
Nut is spirally connected with adjusting screw, and the utility model uses trapezoidal spring controlled valve core, is gone out using the sphere and valve channel of spool
The circular arc sealing surface of mouth disengages closed manners and is turned on and off so as to fulfill valve body valve channel, simple and practical in structure, and
Spaces compact, material consumption is low, can not only save production cost, and improve valve performance.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of new safety valve, including valve body, valve rod,
Spool, trapezoidal spring, spring bonnet, valve seat, fixing nut, adjusting screw, the valve seat are connected with the inner cavity of valve body upper end, institute
State the inner cavity lower end of valve body passage it is suitable for reading set circular arc sealing surface, the valve rod lower end sets spool, upper end sets adjusting screw, described
Spool lower end sets sphere, and the sphere is consistent with circular arc sealing surface radian, and the trapezoidal spring pocket is outside valve rod, under trapezoidal spring
End props up the upper surface of spool, upper end props up the inner face of spring bonnet, after the internal thread of the spring bonnet and valve seat is spirally connected,
After adjusting screw stretches out the upper end of spring bonnet from inside to outside, the fixing nut is spirally connected with adjusting screw.
Further set, the trapezoidal lower spring end is big end, upper end is small end.
Further set, the circular arc sealing surface angle suitable for reading formed with lower mouth is 120 °.
The beneficial effects of the utility model：The utility model uses trapezoidal spring controlled valve core, using spool sphere with
The circular arc sealing surface of valve channel outlet disengages closed manners and is turned on and off so as to fulfill valve body valve channel, simple in structure
Practicality, and spaces compact, material consumption is low, can not only save production cost, and improve valve performance.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the schematic diagram of circular arc sealing surface 101 in Fig. 1.
In figure：Valve body 1, circular arc sealing surface 101, passage 102, valve rod 2, spool 201, sphere 202, trapezoidal spring 3, spring
Bonnet 4, valve seat 5, fixing nut 6, adjusting screw 7.
Embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Fig. 1~Fig. 2, a kind of new safety valve, including valve body 1, valve rod 2, spool 201, trapezoidal spring 3, bullet
Spring bonnet 4, valve seat 5, fixing nut 6, adjusting screw 7, the valve seat 5 are connected with the inner cavity of 1 upper end of valve body, the valve body 1
The passage 102 of inner cavity lower end is suitable for reading to set circular arc sealing surface 101, and 2 lower end of valve rod sets spool 201, upper end sets adjusting screw 7,
201 lower end of spool sets sphere 202, and the sphere 202 is consistent with 101 radian of circular arc sealing surface, and the trapezoidal spring 3 is sleeved on
Outside valve rod 2, beneficial to eliminate work in trapezoidal spring 3 shifting phenomena, trapezoidal 3 lower end of spring prop up spool 201 upper surface, on
End props up the inner face of spring bonnet 4, and after the internal thread of the spring bonnet 4 and valve seat 5 is spirally connected, adjusting screw 7 is from inside to outside
After stretching out the upper end of spring bonnet 4, the fixing nut 6 is spirally connected with adjusting screw 7, and the utility model is controlled using trapezoidal spring
Spool, closed manners are disengaged so as to fulfill valve body valve channel using the sphere of spool and the circular arc sealing surface of valve channel outlet
Be turned on and off, simple and practical in structure, and spaces compact, material consumption is low, can not only save production cost, and improve
Valve performance.
3 lower end of trapezoidal spring is big end, upper end is small end, beneficial to pressure stability, and reduces the material of trapezoidal spring 3
Cost.
The circular arc sealing surface 101 angle suitable for reading formed with lower mouth is 120 °, open-top beneficial to can smoothly be pressurized, and is avoided
Cause sealing contact surface excessive because the radius of circular arc sealing surface 101 and sphere 202 is too small and produce the phenomenon adsorbed.
