Background technology
, it is necessary to use the package encapsulation casing with pressure full of nitrogen in the transport of precision instrument and storage, when
When packing case body temperature or gas componant change, the increased pressure in packing case can be caused, in order to avoid there is packaging casing
Deformation or the accident of cracking, typically install relief valve on packing case, and relief valve can carry out release under dangerous pressure.Due to
Package encapsulation casing is under different environment, and release pressure requirements are different, the vent pressure of general relief valve be it is fixed, no
The change of environment is adapted to, in addition, not pointed out clearly during pressure release, the carelessness of administrative staff is often resulted in, causes safety hidden
Trouble can not be found in time.
The content of the invention
The utility model provides a kind of seal case pressure relief safety valve with buzzer function, solves the pressure release of relief valve
Pressure does not adapt to technical problem easily ignored when the change and pressure release of environment.
The utility model is to solve above technical problem by the following technical programs：
A kind of seal case pressure relief safety valve with buzzer function, including valve body, are provided with through hole, in through hole in valve body
Lower end be bolted with casing connecting adapter, cylindrical through hole with the level is provided with casing connecting adapter, in band
The push rod with cylinder step is movably set with the cylindrical through hole of step, in the top of cylindrical through hole with the level
Ring-shaped step is provided with the wall of side, buzzer is provided with the middle part of the side of valve body, the air intake of buzzer is connected with through hole
Together, the top of the through hole in valve body is provided with backplate lid, is covered in backplate and is provided with adjusting screw by hole, adjusting screw
It is screwed together by the nut in Kong Houyu through holes through adjusting screw, in the side of the cylinder step of the push rod with cylinder step
Middle face is provided with O-ring seals embedded groove, in the upper inner of O-ring seals embedded groove and cylindrical through hole with the level
O-ring seals are provided between the ring-shaped step set on wall, the upper end of spring is socketed on the shank of screw of adjusting screw, spring
Lower end apical grafting on the top surface of the cylinder step of the push rod with cylinder step.
Thimble centring hole is provided with the top surface of the cylinder step of the push rod with cylinder step, centering thimble is that apical grafting exists
In the thimble centring hole set on the top surface of the cylinder step of the push rod with cylinder step, the lower end of spring is apical grafting to middle top
On the top surface of pin；Seal case is connected with casing connecting adapter.
The utility model can automatically be vented and produce alarm sound after the increase of seal case internal pressure；And can
According to the requirement of environment, the setting adjustment of vent pressure is carried out in time, meet the technological requirement of production scene.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This practicality is described in detail below in conjunction with the accompanying drawings：
A kind of seal case pressure relief safety valve with buzzer function, including valve body 4, are provided with through hole 13 in valve body 4,
The lower end of through hole 13 is bolted with casing connecting adapter 11, and cylindrical with the level is provided with casing connecting adapter 11
Through hole 12, is movably set with the push rod 10 with cylinder step, in cylinder with the level in cylindrical through hole 12 with the level
Ring-shaped step 9 is provided with the upper inner wall of bodily form through hole 12, buzzer 6, buzzer are provided with the middle part of the side of valve body 4
6 air intake is connected together with through hole 13, and the top of the through hole 13 in valve body 4 is provided with backplate lid 2, on backplate lid 2
Adjusting screw is provided with by hole, adjusting screw 1 is screwed onto one through adjusting screw by the nut 3 in Kong Houyu through holes 13
Rise, O-ring seals embedded groove is provided with the middle part of the side of the cylinder step of the push rod 10 with cylinder step, in O-ring seals
The sealing of O shapes is provided between the ring-shaped step 9 set on the upper inner wall of embedded groove and cylindrical through hole 12 with the level
Circle 8, the upper end of spring 5 is socketed on the shank of screw of adjusting screw 1, and the lower end apical grafting of spring 5 is in the push rod 10 with cylinder step
Cylinder step top surface on.
Thimble centring hole is provided with the top surface of the cylinder step of the push rod 10 with cylinder step, centering thimble 7 is top
It is connected in the thimble centring hole set on the top surface of the cylinder step of the push rod 10 with cylinder step, the lower end of spring 5 is apical grafting
On to the top surface of middle thimble 7；Seal case is connected with casing connecting adapter 11.The effect of centering thimble 7 can make bullet
The lower pressure of push rod 10 of the spring 5 pairs with cylinder step is uniformly centrally acted on the cylinder step of push rod 10, makes O-ring seals
8 reliable sealings.
When seal case causes internal pressure to increase because of accident or particular surroundings, compressed gas will be from cylinder in seal case
The lower port of bodily form through hole 12 is entered into cylindrical through hole 12, and the push rod 10 with cylinder step is raised upwards, when pushing up
When the strength for rising is more than the lower pressure of push rod 10 of 5 pairs, the spring with cylinder step, the seal failure of O-ring seals 8, compressed gas
Can be entered into through hole 13 by O-ring seals 8, and buzzer 6 is entered by the air intake of buzzer 6, produce buzzer 6
Ring, reminds administrative staff, and the seal box pressure is not normal；When the seal box pressure is reduced to setting value, with cylinder step
Push rod 10 is moved downward in the lower pressure of spring 5, and O-ring seals 8 are compacted, and recovers the sealing effectiveness of O-ring seals 8, honeybee
The ring of ring device 6 stops.Administrative staff can move up and down nut 3, so as to change spring 5 by rotating regulation adjusting screw 1
To the lower pressure of the push rod 10 with cylinder step, seal case pressure release at various pressures is realized.
