The model utility content:
The purpose of this utility model provides that a kind of simple in structure, reliable performance, drag losses are little, power saving, good airproof performance, noise are low, the interlock unloading one-way valve of long service life.
Technical solution of the present utility model: a kind of interlock unloading one-way valve, valve body is arranged, it is characterized in that: in the upper valve body chamber of valve body the off-load spool is housed, on the valve gap of off-load spool upper end the pipe interface that is connected with the air compressor pressure regulator valve is arranged, the upper valve body chamber also has the off-load air outlet, there is valve plate off-load spool lower end, and valve plate is positioned at the upper end with the tank connected valve body lower valve body cavity of gas storage, and there is air compressor pressurized air interface the centre of valve body.
Valve body described in the utility model divides combination to constitute by upper valve body part and middle valve body part, following valve body, and by the fastening connection of screw bolt and nut.Be in upper valve body partly comprises that the upper valve body of cavity, the lower end of upper valve body are equipped with the upper valve base of middle perforate, be fixed with off-load spool guiding supporting base in the upper valve body cavity, between off-load spool and guiding supporting base spring is housed.The sidewall of upper valve body has the off-load air outlet.Be that the middle valve body of cavity, middle valve body side are air compressor pressurized air interface in middle valve body branch comprises, the lower end is the socket that partly connects with following valve body, and there is the valve plate chamber upper end, and aforementioned valve plate is housed in the valve plate chamber, between valve plate and valve plate chamber spring is housed.Following valve body branch comprises valve body down, has under the following valve body and the tank connected interface of gas storage, and the upper shed of following valve body faces aforementioned valve plate.The appearance of valve body has radiated rib.The off-load spool is "T"-shaped structure.
The beneficial effects of the utility model are: the drag losses that simple in structure, ingenious, the reliable performance of design, no common one-way valve cause, power saving, good airproof performance, low, the long service life of noise.
Description of drawings:
Fig. 1 is a kind of structural representation that links during the unloading one-way valve normal working of the present utility model;
Fig. 2 is a kind of structural representation that links during unloading one-way valve off-load working state of the present utility model.
Embodiment:
Fig. 1, Fig. 2 have described an embodiment of the present utility model jointly, and this example is a kind of interlock unloading one-way valve that is used on the air compressor, in this embodiment, valve body 1,2,3 is arranged, and the appearance of valve body 1,2,3 has radiated rib 4.In the upper valve body chamber of valve body off-load spool 5 is housed, off-load spool 5 is "T"-shaped structure.The pipe interface 7 that is connected with the air compressor pressure regulator valve is arranged on the valve gap 6 of off-load spool 5 upper ends, the upper valve body chamber also has off-load air outlet 8, there is valve plate 9 off-load spool 5 lower ends, and valve plate 9 is positioned at the upper end with the lower valve body cavity of the tank connected valve body of gas storage, and there is air compressor pressurized air interface 10 centre of valve body.Described valve body divides combination to constitute by upper valve body part and middle valve body part, following valve body, and by bolt 11 and nut 12 fastening connections.Be in upper valve body partly comprises that the upper valve body 1 of cavity, the lower end of upper valve body 1 are equipped with the upper valve base 13 of middle perforate, be fixed with off-load spool 5 guiding supporting bases 14 in upper valve body 1 cavity, off-load spool 5 and 14 of supporting bases of guiding are equipped with spring 15.The sidewall of upper valve body 1 has off-load air outlet 8.Be the middle valve body 2 of cavity in middle valve body branch comprises, middle valve body 2 sides are air compressor pressurized air interface 10, and the lower end is the socket that partly connects with following valve body, and there is the valve plate chamber upper end, and aforementioned valve plate 9 is housed in the valve plate chamber, between valve plate 9 and valve plate chamber spring 16 is housed.Following valve body branch comprises valve body 3 down, and following valve body has for 3 times and the tank connected interface 17 of gas storage, and the upper shed of following valve body 3 faces aforementioned valve plate 9.
Working principle of the present utility model:
During the air compressor proper functioning (as shown in Figure 1), pressurized air is entered by the interface 10 of middle valve body 2, enter air compressor air storage tank through the valve clearance passage from following valve body 3, valve plate 9 seals with the upper valve base applying under the effect of spring force and gas force, make air compressor in exhaust process, pressurized air can be from the off-load air outlet 8 leak, when reaching rated pressure, the air compressor pressure regulator valve is opened, the utility model enters unloading condition (as shown in Figure 2), pressurized air enters in the upper valve body from valve gap, promote off-load spool 5, off-load spool 5 makes valve plate 9 move down rapidly again, with the sealing of fitting of the sealing surface of following valve body upper end, pressurized air in the gas holder can not be flow backwards and reaches the effect of safety check, and meanwhile, form the exhaust passage between valve plate 9 and the upper valve base 13, the pressurized air that air compressor is discharged by the exhaust passage from 8 emptying of off-load air outlet, thereby reach the purpose of off-load.
