Description
Technical field
The present invention relates to pressure regulator valve field, be specifically related to the improved structure of pressure regulator valve.
Background technique
Type and the material of current valve get more and more, and the model establishment of valve is also more and more complicated.Though the unified standard that China has valve model to work out, the needs of valve industry development more and more can not be adapted to.Different according to the effect of opening/shutting valve, valve sorting technique is a lot, but mainly classifies by its role in pipeline.Industry and civil engineering in General valve can be divided into 11 classes, i.e. gate valve, stop valve, stopcock, ball valve, butterfly valve, membrane valve, safety check, throttle valve, safety valve, reduction valve and drain valve.Pressure regulator valve is that Lever type Pressure difference feedback controls pressure regulation.Combustion gas in gas cylinder is liquid, and pressure is too high, must reduce pressure and just be applicable to burning.Also need to use pressure regulator valve in field of petroleum machinery, existing pressure regulator valve in use valve rod mobile seamed edge under long-term gas pressure can wear and tear, thus offsets, and affects the movement of its band moving valve upper valve core.In addition, valve seat does not arrange supporting mechanism, easily produce in the process of valve rod movement and rock, be in use easily damaged and misplace.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, the improved structure of pressure regulator valve is provided, arrange major axis in the substantially horizontal of valve rod to hold out against it, prevent valve rod from single direction wearing and tearing occurring in Long-Time Service process and produces skew, cushion block is set in the bottom of pedal, even if the little loosening angle stabilization that also can ensure between pedal and valve seat appears in pedal movable end simultaneously.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the improved structure of pressure regulator valve, comprise valve rod, spool and valve body, spool is positioned at the cavity of valve body, valve rod is connected to the top of valve body, also comprise pedal, valve seat, cushion block, supporting element and major axis, spool wherein can move axially along valve body; The top connecting valve seat of described valve rod; Described pedal one end is movably connected in the top of valve seat, and the other end is unsettled, and between the bottom and valve seat of pedal, go back linking springs and cushion block, cushion block is between spring and the flexible connection end of pedal; Described major axis level crosses supporting element and end holds out against the outer wall of valve rod.
Described cushion block and spring are all perpendicular to pedal.
The top of described supporting element holds out against the bottom of valve seat.
Described supporting element and the top of valve body integrative-structure and perpendicular to major axis each other.
The flexible connection end of described pedal to be connected on step that valve seat exceeds and adjacent with cushion block.
Described major axis and substantially horizontal are acute angle.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is provided with major axis, hold out against from the side of substantially horizontal to valve rod, prevent valve rod from single direction wearing and tearing occurring in Long-Time Service process and produces skew, major axis is wherein fixed by supporting element, ensure the clamping effect that major axis reaches best, the top of supporting element also can support valve seat simultaneously simultaneously.
2, between pedal and valve seat, be also provided with cushion block, even if the little loosening angle stabilization that also can ensure between pedal and valve seat appears in pedal movable end due to Long-Time Service, ensure that Compress Spring is to the adjustment of pressure size, ensure that the stable of this modulating valve performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, reference character is expressed as: 1, pedal; 2, spring; 3, valve seat; 4, valve rod; 5, spool; 6, valve body; 7, cushion block; 8, supporting element; 9, major axis.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited thereto.
Embodiment:
As shown in Figure 1, the present invention includes valve rod 4, spool 5 and valve body 6, spool 5 is positioned at the cavity of valve body 6, valve rod 4 is connected to the top of valve body 6, also comprise pedal 1, valve seat 3, cushion block 7, supporting element 8 and major axis 9, spool 5 wherein can move axially along valve body 6, and the top of supporting element 8 holds out against the bottom of valve seat 3, the top of supporting element 8 and valve body 6 integrative-structure and perpendicular to major axis 9 each other.
The top connecting valve seat 3 of described valve rod 4.Pedal 1 one end is wherein movably connected in the top of valve seat 3, and the other end is unsettled, goes back linking springs 2 and cushion block 7 between the bottom of pedal 1 and valve seat 3, and cushion block 7 is between spring 2 and the flexible connection end of pedal 1, and cushion block 7 and spring 2 are all perpendicular to pedal 1.
The flexible connection end of pedal 1 to be wherein connected on step that valve seat 3 exceeds and adjacent with cushion block 7, and major axis 9 and substantially horizontal are acute angle.Major axis 9 level of the present embodiment crosses supporting element 8 and end holds out against the outer wall of valve rod 4.
Only need jam on pedal top compression spring during use, owing to being also provided with cushion block between pedal and spool, spring can not compress completely, and occurs the situation of Powerful Rebound, the stability of guaranteed performance.Then according to the principle that spring force and pressure balance each other, when the pressure of spring is less than air pressure time, valve cuts out, pressurized air below rubber voltage regulation diaphragm when pressure is greater than the elastic force of spring time below base is to the active force of diaphragm, promotion diaphragm upwards arching is lifted off a seat and passes air into air cavity, now valve rod moves under gas pressure, by the valve open on valve body, dally so the air being filled with air cavity by air compressor just enters atmospheric air compressor by valve.And in the process that valve rod moves axially under pressure, the major axis of substantially horizontal holds out against support to valve rod wall, avoid its run-off the straight and occur that single direction weares and teares, after Long-Time Service, also there will not be single direction to offset.And major axis is by being fixed with the supporting element of valve body structure, ensure its fastening soundness, simultaneously supporting element also can support valve seat, and rock even if ensure that the excessive situation of its pressure also there will not be, modulating valve performance is more firm.
Just this invention can be realized as mentioned above.
