Abstract
A valve, in particular to an energy-saving respiration valve that is arranged in the oil tank respiration pipe for reducing the volatilization of oil gas, comprises a valve ring, an upper catch, a lower catch, an upper shaft, a lower shaft and an isolating plate. The upper catch is at a downward closed state under the gravity, while the lower catch is at an upward closed state under the reverse acting force. The upper and lower catches are closed so as to block off the volatilization of the oil gas. When the pressure of oil gas continuously ascends and then is larger than the gravity of the upper catch, the upper catch is opened and then the oil gas volatilizes slowly owing to the large pressure of the oil gas as to reduce the volatilization of the oil gas. When the oil pumping pressure of the oil tank is lower than the atmospheric pressure, the lower catch is opened under the atmospheric pressure and then the oil in the oil tank is pumped.
Description
Technical field
The utility model relates to a kind of valve with energy-conserving action, specifically is installed on the energy-conservation breathing valve that can reduce oil gas volatilization in the breathing pipe of oil tank.
Background technology
Because gasoline, diesel oil etc. have volatility, so petrol storage tank is for the storage oil product of safety and extract the oil product product smoothly, oil tank has all been installed breathing pipe, and the oil gas that causes volatilizing directly is discharged in the air, and the direct discharging of this oil gas has just caused the high loss and the environmental pollution problems of oil product.
The utility model content
Technical problem to be solved in the utility model provides a kind of pipe safety dumping oil gas and oil tank of can ensuring respiration and extracts oil product smoothly, can reduce a kind of energy-conservation breathing valve of oil loss again.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of energy-conservation breathing valve, it is made up of valve circle, upper stop piece, lower stop piece, last axle, lower shaft, dividing plate, divider upright is positioned at valve circle middle part, last axle is positioned at the top of dividing plate and captives joint with the valve circle, lower shaft is positioned at the following of dividing plate and captives joint with the valve circle, last axle is gone up washer by movable connection of axle sleeve, and lower shaft is by the movable lower gear plate that connects of axle sleeve.
Because it is big more that oil gas has pressure, the slow more characteristic of volatilize between the ultimate pressure value and normal atmosphere (An) value of oil tank, is chosen the storage oil product that purpose that a suitable force value just can reach the minimizing oil loss guarantees oil tank safety simultaneously.The further improvement project that the utility model is done is: the valve circle is made up of outer ring and inner ring, the valve circle is provided with locating pin, upper stop piece two axle sleeves that have been fixedly connected, spacing card one end also is fixedly connected between two axle sleeves that upper stop piece is fixedly connected, upper stop piece is provided with clump weight, and last clump weight is detachable the connection with upper stop piece; Lower stop piece two axle sleeves that have been fixedly connected, being fixedly connected between two axle sleeves that lower stop piece is fixedly connected one connects bar, and following clump weight and connecting strap are detachably to be linked together.
The further improvement project that the utility model is done is: dividing plate length equals the diameter of inner ring, the dividing plate height equal inner ring height; Dividing plate and valve circle are fixedly connected, and the spacing card other end is equipped with spiral nail; Last axle two ends and lower shaft two ends all are with two back-up rings.Back-up ring has limited the position that upper stop piece and lower stop piece move, and has reduced the impact to the valve circle of upper stop piece and lower stop piece.
Oil gas volatilization in oil tank, oil gas rises in jar, and following clump weight will be because self gravitation will react to lower stop piece by connecting bar, and the closed condition that keeps lower stop piece to push up on inner ring has stoped the volatilization of oil gas; Simultaneously because upper stop piece is connected with clump weight, oil gas can not volatilize, oil gas continues to rise in jar, pressure increases, pressure below the upper stop piece is greater than last surface pressure, and upper stop piece is opened, when upper stop piece is opened to certain angle, the spiral nail that the spacing card other end is installed just withstands dividing plate, has guaranteed that the angle that upper stop piece is opened along horizontal surface can be greater than 90 degree.When oil tank extracts oil product, jar internal pressure descends, and when the jar internal pressure dropped to the lower stop piece base pressure and is lower than barometric pressure, lower stop piece was opened, and an oil product is forced out in jar.
The beneficial effects of the utility model are, by lower stop piece being opened the design with closed condition, guarantee that oil tank can extract oil product smoothly; The design appropriateness that upper stop piece is opened with closed condition has increased the oil gas pressure simultaneously, and the evaporation rate of the oil gas that slowed down has been saved the energy, has also reduced pollution.

Clump weight on 1. among the figure, 2. upper stop piece, 3. axle sleeve is 4. gone up axle, 5. spacing card, 6. spiral nail, 7. locating pin, 8. valve circle (inner ring), 9. valve circle (outer ring), 10. dividing plate, 11. lower stop pieces, 12. times clump weights, 13. connect bars, 14. axle sleeves, 15. lower shafts, 16. back-up rings.
The specific embodiment
The utility model is as shown in Figure 1: energy-conservation breathing valve by valve circle (inner ring) 8 and valve circle (outer ring) 9, upper stop piece 2, lower stop piece 11, go up axle 4, lower shaft 15, dividing plate 10 and form, dividing plate 10 vertically is positioned at the middle part of valve circle (inner ring) 8, it is fixing with valve circle (outer ring) 9 that last axle 4 is positioned at the top of dividing plate 10, it is fixing with valve circle (outer ring) 9 that lower shaft 15 is positioned at the following of dividing plate 10, last axle 4 is connected with washer 2 by axle sleeve 3 activities, and lower shaft 15 is connected with lower gear plate 11 by axle sleeve 3 activities.Valve circle (inner ring) 8 and valve circle (outer ring) 9 are provided with locating pin 7, upper stop piece 2 two axle sleeves 3 that have been fixedly connected, spacing card 5 one ends that also have been fixedly connected between two axle sleeves 3 that upper stop piece 2 is fixedly connected, upper stop piece 2 is provided with clump weight 1, and last clump weight 1 is detachable connections with upper stop piece 2; Lower stop piece 11 two axle sleeves 3 that have been fixedly connected, being fixedly connected between two axle sleeves 3 that lower stop piece 11 is fixedly connected one connects bar 13, and following clump weight 12 is detachably to be linked together with connecting strap 13.
The utility model is as shown in Figure 3: oil gas volatilization in oil tank, oil gas rises in jar, following clump weight 12 will be because self gravitation will react to lower stop piece 11 by connecting bar 13, and the closed condition that keeps lower stop piece 11 to push up on valve circle (inner ring) 8 has stoped the volatilization of oil gas; Simultaneously because upper stop piece 2 is connected with clump weight 1, oil gas can not volatilize, oil gas continues to rise in jar, pressure increases, pressure below the upper stop piece 2 is greater than last surface pressure, and upper stop piece 2 is opened, when upper stop piece 2 is opened to certain angle, the spiral nail 6 that spacing card 5 other ends are installed just withstands dividing plate 10, has guaranteed that the angle that upper stop piece 2 is opened along horizontal surface can be greater than 90 degree.Be subjected to the restriction of back-up ring 16 during upper stop piece 2 moves along last 4, reduced upper stop piece 2, reduced the impact of 2 pairs of valve circles of upper stop piece (outer ring) 9 along last axle 4 direction plaies.
