Description
Technical field
The utility model relates to a kind of field of air compressor, and more particularly, it relates to a kind of exhaust valve component.
Background technique
Air compressor is modern basic product, it is the device former dynamic mechanical energy being converted to gas pressure energy, it is compressed-air actuated generating means, mainly be stored into again in gas holder by forming high-pressure air after cylinders compressing air, built in gas tank has outlet valve, pressurized gas are entered in gas holder by outlet valve and store, and can ensure that pressurized gas are not revealed.
Exhaust valve component mainly comprises valve seat, valve gap and valve block, one-way sealing is realized by valve block, valve gap and valve seat pass through Stud connection, backing down valve block when pressurized gas enter makes gas pass through to enter in gas holder, when not using, valve block is sealed into pore, therefore in exhaust valve component using process, valve block moves axially along stud, and it is rapid, and then very large friction will inevitably be produced, and due to valve block be all made by rubber usually, wear no resistance, easy appearance damages, affect the normal use of exhaust valve component, need during maintain and replace to change whole valve block, valve block cost is higher, and then add maintenance cost, be further improved.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of exhaust valve component.
For achieving the above object, the utility model provides following technological scheme: a kind of exhaust valve component, comprise valve seat and valve gap, described valve seat and valve gap are by Stud connection, and described valve seat is provided with inlet hole, and described valve gap is provided with the air outlet hole be communicated with inlet hole, the valve block of one-way flow has been provided with between described valve seat and valve gap, described valve block is loop configuration, described stud is arranged with the support ring coordinated with valve block, and described support ring is plastic material.
Further, described valve block is provided with inlet hole in the vent shifted to install, and described vent is corresponding with air outlet hole to be arranged, and described valve gap is provided with mounting groove, is provided with valve block is compressed the elastic component blocking inlet hole in described mounting groove.
Further, described inlet hole is cone shape hole, and described inlet hole is less than opposite side near valve gap one side opening.
Further, the shape of described air outlet hole is arc, and described air outlet hole is circumferentially uniformly distributed.
Further, described air outlet hole is cone shape hole, and the opening of described air outlet hole near valve seat side is less than opposite side.
Compared with prior art, the utility model has the advantage of: by support ring sheathed on stud, diaphragm inner ring hollow portion filled by support ring, diaphragm is filled by support ring and is supported, and then diaphragm can be avoided directly to contact with the direct of stud, outlet valve in use diaphragm and stud relative movement is avoided to occur the situation of wearing and tearing, and support ring is plastic material, plastic material not only cost is low, and wear resistance is had more compared with rubber material, ensure that outlet valve uses for a long time normally, even if also only need support ring be changed because damaging appears in friction, without the need to changing diaphragm, and then reduce maintenance cost to a great extent.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model exhaust valve component embodiment;
Fig. 2 is the structural drawing of the utility model exhaust valve component embodiment;
Fig. 3 is the structural drawing of the utility model exhaust valve component embodiment.
Reference character: 1, valve seat; 2, valve gap; 3, stud; 4, inlet hole; 5, air outlet hole; 6, valve block; 7, vent; 8, support ring; 9, mounting groove; 10, spring.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model exhaust valve component embodiment is described further.
A kind of exhaust valve component, comprise valve seat 1 and valve gap 2, valve seat 1 is connected by stud 3 with valve gap 2, valve seat 1 is provided with inlet hole 4, valve gap 2 is provided with the air outlet hole 5 be communicated with inlet hole 4, has been provided with the valve block 6 of one-way flow between valve seat 1 and valve gap 2, and valve block 6 is loop configuration, stud 3 is arranged with the support ring 8 coordinated with valve block 6, support ring 8 is plastic material.
Its middle valve plate 6 is provided with inlet hole 4 in the vent 7 shifted to install, and vent 7 is corresponding with air outlet hole 5 to be arranged, and valve gap 2 is provided with mounting groove 9, is provided with valve block 6 is compressed the elastic component blocking inlet hole 4 in mounting groove 9.
Exhaust valve component is not when using, valve block 6 to be pressed on valve seat 1 and to be sealed into pore 4 under elastic component effect, preferred elastomeric part is spring 10, to enter from inlet hole 4 at outlet valve using process mesohigh gas and back down valve block 6, inlet hole 4 is communicated with by the vent 7 on valve block 6 with air outlet hole 5, and then pressurized gas are discharged from exhaust port, by support ring 8 sheathed on stud 3, diaphragm inner ring hollow portion filled by support ring 8, diaphragm is filled by support ring 8 and is supported, and then diaphragm can be avoided directly to contact with the direct of stud 3, outlet valve in use diaphragm and stud 3 relative movement is avoided to occur the situation of wearing and tearing, and support ring 8 is plastic material, plastic material not only cost is low, and wear resistance is had more compared with rubber material, ensure that outlet valve uses for a long time normally, even if also only support ring 8 need be changed because damaging appears in friction, without the need to changing diaphragm, and then reduce maintenance cost to a great extent.
Wherein inlet hole 4 is cone shape hole, and inlet hole 4 is less than opposite side near valve gap 2 one side opening.
Wherein air outlet hole 5 is cone shape hole, and the opening of air outlet hole 5 near valve seat 1 side is less than opposite side.
By such design, when pressurized gas enter from inlet hole 4, taper due to inlet hole 4 is arranged can pressurize to pressurized gas further, by exhaust port discharge be stored in gas holder, because the opening of exhaust port near valve seat 1 side is less than opposite side, can play and necessarily reduce gas flow rate, and then the noise that outlet valve Exhaust Gas produces can be reduced to a certain extent.
Further, the shape of air outlet hole 5 is arc, and air outlet hole 5 is circumferentially uniformly distributed.
Air outlet hole 5 as shown in drawings distributes, can the discharge that guarantee pressurized gas are good while, can increase again the air displacement of air outlet hole 5 on valve gap 2, the vent 7 on preferred valve block 6 and the air outlet hole 5 on valve gap 2 be corresponding to be arranged and shape is also identical, and then can gas displacement to greatest extent.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
