Abstract
The present invention is a kind of full mechanicalness valve that can block a large amount of gas leakage side canals automatically.It mainly is suitable for gas braking type vehicle.It is that interior duplex valve block by spring-loaded is formed by sky clothes Three way type valve body.Valve block is harmonious with the valve end of gas leakage side when wherein having one the tunnel to leak gas in a large number during its work, reaches to close gas leakage side branch road purpose automatically.
Description
The present invention is a kind of then full mechanicalness valve of passage of a large amount of gas leakage of closing automatically, and it mainly is suitable for gas braking type vehicle.
The gas of some vehicle braking at present is that direct-connected threeway mode is worked, in case interior whole gas braking of short time was out of hand when a branch road seriously leaked gas, also the single prosecutor formula of multichannel is taked in some vehicle gas braking, complicated, cost is high, can move after must handling when serious gas leakage appears in above-mentioned air braking system.
Main task solved by the invention is the added security valve, and it can be closed the along separate routes serious gas leakage of vehicle gas braking automatically and then improve gas braking reliability, and does not in case of emergency handle gas leakage feasibility operation along separate routes.
Main action of the present invention is at columnar valve wall middle part, sky clothes garden main gas tube to be arranged, two ends link with a shunt air chamber and form a threeway dress attitude, have in the valve chamber by branch road two ends in the lightweight garden shape duplex valve block that certain intensity is arranged of adjustable pressure spring-loaded, it and the valve certain distance is arranged, keep certain interval with the valve wall, valve block is outlying some air flues.
The next body of calming the anger to main line flows to branch airway by gas circuit between valve block and valve wall, when the pressure difference that two valve blocks are produced by gas is not more than fixed pressure spring pressure, the duplex valve block is in neutral position formation threeway dress attitude in the valve, in case wherein a branch road flow heightens, when the uniaxial pressure that corresponding valve block is subjected to surpassed respective springs pressure, valve block was close to the valve end that leaks gas then and reaches and close purpose.
In conjunction with the accompanying drawings the present invention is further described
Figure one is a concrete structure schematic representation of the present invention.
Figure two is 4. 5. front views of valve block.
Figure three is stop valve working position schematic representation.
With reference to figure one, 9. 1. the empty clothes of garden post valve body have main tracheae in the middle part, two end cap 2. 3. the middle part bronchus 10. (11) arranged, valve body 1. and two end cap 2. sealing gasket is arranged between 3., adjust sealing gasket (13) thickness can change branch road 10. or (11) close sensitivity, valve body is 1. 2. 3. fastening by screw (14) with end cap, the valve block that valve body has the long nut one in 1. first 4., another valve block that long bolt one then arranged 5., two valve blocks are 4. 5. by separately nut, screw rod combines into adjustable one, two valve blocks are 4. 5. by 7. 8. supporting of spring, 6. be that Gu is Dinged the 1. 7. 8. center bearing bracket of spring at middle part of Zai Valve body, valve block is 4. 5. outlying an air flue (15), valve body 1. and valve block 4. 5. between gapped (12).
By valve block 4. 5. the screw edge of a knife (16) rotary valve plate 4. 5. screw in conjunction with length, just change valve block 4. 5. between length and spring 7. 8. pressure and valve block 4. 5. and the valve end cap 2. 3. between distance, regulated 4. 5. action sensitivity of valve block.
Come to main airway gas 9., 1. 4. 5. gap (12) and valve block air flue (15) flow to branch airway 10. (11) with valve block through valve body, leak gas in case branch road 10. or (11) are a large amount of, through valve block 5. or tolerance 4. increase, valve block 5. or the uniaxial pressure that 4. is subjected to 7. or 8. along with strengthen surpassing spring pressure the time, 10. or (11) 5. or 4. valve block is close to the valve end and 2. or 3. closes branch road.
Claims (3)
1,1. wall middle part has main airway sky clothes garden column valve body 9., the end cap that there is a branch airway at the middle part 2. 3., the duplex valve block 4. 5., the valve that 8. 7. pressure spring formed, the valve block that it is characterized in that the nut one 4. with the valve block of screw rod one 5., by 7. 8. supporting of pressure spring.
2, by the described device of claim 1, it is characterized in that valve block 4. with valve block 5. by separately nut, screw rod is combined into the one of can regulate working sensitivity.
3, by claim 1 and 2 described devices, it is characterized in that spring 7. 8. pressure with valve block 4. 5. adjusting change.
