Supply a chamber 22 connection.
The working principle of intermittent steam supply valve of the invention is summarized as follows:
First stage: when inlet charge, air-flow is entered by the E mouth of air inlet 6 indirectly for the Z-type of air cavity 2 simultaneously respectively
Two-fold angle air supply channel 23, two chambers 19 are directly supplied by G mouthfuls of entrance, the gas process into indirect inlet chamber 2 is built in spiral shell
Enter the first air cavity 6 by I mouthfuls after the needle-like adjusting nut 1 of female built-in hole 24, the gas into two chambers 19 of direct gas supply passes through again
It is led into the first air cavity due to the needle-like adjusting nut 1 being arranged in indirect inlet chamber 2 after crossing directly one chamber 22 of gas supply by D mouthfuls
It causes to act on D mouthfuls of time ratio of inlet piston 5 into the first air cavity 6 by I mouthful and acts on inlet piston 5 into the first air cavity 5
It is short, so gas enters the first air cavity 6 by directly two chambers 19 of gas supply and directly one chamber 22 of gas supply acts on air inlet first
On piston, while being discharged from the H mouth of the C mouth of the first venthole 7 and transition separate space 13, the gas being discharged from the C mouth of the first venthole 7
Body enters executive component.
Second stage: the gas entered from the H mouth of transition separate space 13 acts on the air bleed piston 14 in the second air cavity 11,
Air bleed piston 14 blocks the B mouth of the second venthole 9, and gas is by entering the first air cavity 6 for air cavity 2 indirectly at the same time
Gas act on inlet piston 5, then inlet piston 5 blocks the C mouth of the first venthole 7, and directly gas supply one
The D mouth of chamber 22 is in closed state, so that the F mouth of the first air cavity air leakage hole 3 be made to be connected to the H of transition separate space 13 mouth by the second gas
Gas in chamber 11 is bled off, and air bleed piston 14 is moved to initial position under the action of reset spring 10, then the second venthole 9
B mouth be again turned on and be connected to the A mouth of the second air cavity air leakage hole 12, enter executive component from the C mouth of the first venthole 7
Gas is bled off by the B mouth of the second venthole 9, and after the gas in executive component is bled off, the gas of the first air cavity 6 is from the first gas
The F mouth of chamber air leakage hole 3 bleeds off rear inlet piston 5 and is moved to initial position under the action of reset spring 10.
Phase III: it is completed when inlet piston 5 restores initial position the latter intermittent gas supply circulation, then repeatedly the first rank
The gas supply process of section and second stage.
The above specific embodiments are only exemplary, is to preferably make skilled artisans appreciate that originally
Patent, be not to be construed as include to this patent range limitation, as long as any made by the spirit according to disclosed in this patent
Equivalent change or decoration, each fall within the range that this patent includes.
