Description
Technical field
Safety valve field is the utility model is related to, more particularly to a kind of oxygenerator safety valve.
Background technology
Safety valve is that opening and closing element is in normally off under by external force effect, when the pressure medium rise in equipment or pipeline is super
When crossing setting, by outside system discharge medium prevent the pressure medium in pipeline or equipment from exceeding the particular usage valve of specified value
Door.
Oxygenerator used safety valve generally existing in the market, unlatching noise is big when safety valve works, uses the longevity
Order the problem of short and valve body structure is long.The problem of noise is big does not conform to mainly due to valve body of safety valve and the design of valve rod fit clearance
Reason, spring end design are unreasonable；It is split type that the problem of service life is short, which is primarily due to current valve pad and valve rod, and valve pad is strong
Degree not enough causes safety valve service life short；The problem of valve body structure is long is primarily due to sealing surface of safety valve and venthole
Position Design is unreasonable, the problem of causing valve body structure long.
Therefore it is badly in need of solving the problems, such as that unlatching noise is big, service life is short and valve body structure is long.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of oxygenerator safety valve, by the end for changing spring
Structure gap appropriate with setting in portion's is avoided that safety valve produces noise at work, and service life is grown, and structure is short and small compact.
Technical scheme is used by the utility model solves its technical problem：A kind of oxygenerator safety valve is provided, wrapped
Valve body and valve rod are included, described valve rod and the stem head of its lower end are integrally formed and be disposed axially in valve body, described valve body
Lower end be air inlet, the lower end insertion of described stem head is provided with sealing gasket, and sealing gasket seals the upper end of air inlet, institute
Set screw is cased with the outside of the upper end for the valve rod stated, the outside of the set screw is threadedly coupled with valve body madial wall, and its lower end
Stem exterior between stem head is socketed with spring, and the both ends end of described spring and stem head and set screw connect
Contacting surface is non-anchor ring, and venthole is provided with the middle part of described valve body.
Preferably, described sealing gasket is made up of elastomeric material, the sealing gasket vulcanizes in the groove of valve rod cephalic par
Shaping.
Further preferred, the lower end disposed outside of described valve body has threaded joints, the upper end of the threaded joints
Higher than the upper surface of air inlet.
Further preferred, the upper surface of described air inlet is disposed with a circle boss, and the boss is in contact with sealing gasket.
Further, the gap between the lateral wall of described stem head and the madial wall of valve body is 0.5~0.6mm.
Beneficial effect：A kind of oxygenerator safety valve is the utility model is related to, it is simple and compact for structure, have the characteristics that：
(1) by increasing the fit clearance of valve rod and valve body, the value control in gap is opened in unilateral 0.5~0.6mm, quickening safety valve
The emptying of gas afterwards；(2) end of spring is designed to not Cheng Yuan form, causes the sealing surface eccentric force of sealing gasket, from
Without allowing safety valve the action of moment opening and closing occur, safety valve is avoided to produce noise at work；(3) rubber is made
Sealing gasket vulcanization to inside valve rod, to improve the intensity of sealing gasket, the service life of safety valve is improved from face；(4) by valve body
The design that moves down of sealing surface, the space of valve body installation screw thread is made full use of, to reduce valve body structure length.
Brief description of the drawings
Fig. 1 is full-gear three-dimensional structure diagram of the present utility model.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As shown in figure 1, embodiment of the present utility model is related to a kind of oxygenerator safety valve, including valve body 1 and valve rod
4, described valve rod 4 and the stem head 9 of its lower end are integrally formed and are disposed axially in valve body 1, and the lower end of described valve body 1 is
Air inlet 6, the lower end insertion of described stem head 9 are provided with sealing gasket 8, and sealing gasket 8 seals the upper end of air inlet 6, described
Valve rod 4 upper end on the outside of be cased with set screw 2, the outside of the set screw 2 is threadedly coupled with the madial wall of valve body 1, and under it
Spring 3, both ends end and stem head 9 and the regulation of described spring 3 are socketed with outside valve rod 4 between end and stem head 9
The contact surface of screw 2 is non-anchor ring, and the middle part of described valve body 1 is provided with venthole 5.
Its operation principle is：When oxygen making set system pressure exceedes setting, safety valve is opened, by the part in system
Gas is discharged, and system pressure is no more than permissible value, so as to ensure that because of hypertonia accident does not occur for system.
