Abstract
The utility model relates to a strip-shaped inspiration valve for a compressor, which is characterized in that the utility model is composed of a valve plate, a lifting range limiter, a strip-shaped inspiration valve sheet, etc., wherein, one end of the valve sheet is fixed in the lifting range limiter. An inspiration channel of the valve plate is sealed by the other end of the valve sheet, and the valve sheet can do opening motion in the lifting range limiter. The utility model has the advantages of small size, small stress and valve sheet material saving, and two, or three, or four valve sheets can be arranged in the lifting range limiter.
Description
The utility model relates to a kind of strip Aspirating valves of compressor.
Existing compressor, especially piston type microminiature air compressor use tongue Aspirating valves as shown in Figure 1 mostly.This class Aspirating valves is fixed on an end of reed valve plate 2 on the valve plate 1, and its other end covers the air-flow path 6 of valve plate, and after valve block was opened, air-flow flowed out through passage, and the lift of valve block is by the control of the restriction of the lift on cylinder breach.Because the length and the width of this class Aspirating valves are all bigger, thereby the elastic force and the stress that produce are also bigger, so cause valve block to damage easily.
The purpose of this utility model just provides a kind of low stress compressor strip Aspirating valves cheaply, its strip valve block is to be contained in the lift limiter, one end is fixed on the valve plate, the other end seals up the air intake passage of valve plate, when air-flow sucks, open, suck with air-flow and stop and closing, because this strip Aspirating valves length is short, width is narrow, so the elastic force of valve block is also just smaller, so its stress is also smaller.Owing to use material fewer, cost is also just lower.
The purpose of this utility model is to realize like this, as shown in Figure 2: screw 11 is fixed on lift limiter 9 and strip valve block on the valve plate 7, valve block in the lift limiter covers the air-flow path 10 on the valve plate, valve block can be made opening movement in lift limiter, in order to guarantee that air motion has enough passages, air-flow path is left in the both sides and the centre at lift limiter middle part.
Owing to take such scheme, compressor strip Aspirating valves of the present utility model has the stress lower than the valve block of existing tongue Aspirating valves, consequently obtains the working life of air valve prolonging.And valve block boundary dimension of the present utility model has also just reduced the consumption of valve plate material less than the reed valve plate size of the same specification of prior art.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the worm's eye view of existing tongue Aspirating valves.
Accompanying drawing 2 is worm's eye views of a kind of embodiment of the present utility model.
Accompanying drawing 3 is worm's eye views of another kind of embodiment of the present utility model.
Now, be illustrated according to Fig. 2 with a kind of embodiment of the present utility model.Present embodiment is that two beam valve sheets are contained in the situation in the lift limiter.During the work of the Aspirating valves of compressor, if valve plate 7 have draught head up and down, suck gas and will push suction valve chip open through the air-flow path 10 of valve plate, enter in the cylinder through the both sides and the middle air-flow path of lift limiter 9.Screw 11 is fixed on lift limiter 9 and suction valve chip on the valve plate 7, makes the working state of the similar overhang of suction valve chip.The lift of valve block is by the degree of depth control of lift limiter.The valve plate of a whole set of air valve is installed between cylinder and the cylinder head with screw 8.
Owing to take such scheme, the utility model compared with prior art, it is short to have valve block length, width is narrow, elastic force is little, the stress of valve plate is reduced greatly, obtain the working life of valve block prolonging, and materials economizes, and has also just reduced manufacture cost.In addition because installation of the present utility model divides half form in still adopting partially, so parts such as cylinder of compressor lid can be used as it is the parts such as cylinder head of former Reed Valve.
Accompanying drawing 3 is another kind of embodiments of the present utility model, is that three beam valve sheets are contained in the situation in the lift limiter on the figure, is applicable to the cylinder bore situation of some greatly.The utility model embodiment can singlely be provided with, and also several can be merged to use and form a cover combination brake switch and proporting, and for example combination more than four is applicable to the situation that cylinder bore is bigger.The utility model is specially adapted to the compressor of 100～200 millimeters of cylinder bores.
Claims (3)
1, a kind of strip Aspirating valves of compressor, comprise valve plate 7, lift limiter 9 and strip suction valve chip, it is characterized in that the strip valve block that is contained in the lift limiter is that an end is fixed on the valve plate, the other end covers the air intake passage 10 of valve plate, and valve block can be made opening movement in lift limiter.
2, compressor strip Aspirating valves according to claim 1 is characterized in that being provided with in the lift limiter lift of valve plate of regulation, and air-flow path is also left in the both sides of lift limiter and centre, and lift limiter is fixed in the valve plate with screw 11.
3, compressor strip Aspirating valves according to claim 1 is characterized in that can adorning two valve blocks in a lift limiter, also can adorn three valve blocks, can also adorn four valve blocks.
