Abstract
An automatic drainage device for loader brake system comprises a valve body, a valve cap, a leather cup, a filter, a spring and a guide bar. The top of the valve body is arranged with a filter. The seal ring rack of the valve body is arranged with a seal ring. The bottom of the leather cup on the leather cup rack inside the valve body is a cone contacting the conical surface of the valve cap. Spring is arranged around the leather cup. The valve cap and the leather cup are crossed through by the guide bar. Top end of the valve cap is sleeved with seal ring and the bottom end is arranged with collar. When the brake air pressure changes between 30kPa and 100kPa, the leather cup can move fast upward and downward, thereby opening and closing the valve. The device can drain the ponded water inside air passage effectively while saving the labor, so as to prevent the rusting of braking element due to the condensation of water content and assure the flexibility and reliability of the loader.
Description
Technical field
The purpose of this utility model provides a kind of water that can automatically loader be braked condensation in the system gas road and discharges the outer device of gas circuit.
Background technology
What loader braking system generally adopted is that compressed air is done power enforcement braking, owing to contain moisture content in the air, after water enters in the gas circuit, can make braking member produce corrosion, causes loader the phenomenon of brake failure to occur.
At present, in loader braking system gas road a discharging valve is housed all, this discharging valve need be opened by manpower and discharge water, put water after, close this valve by manpower again.Because need by manpower, the water that accumulates in the gas circuit is difficult to accomplish in time to discharge outside the gas circuit.
Summary of the invention
The purpose of this utility model provides a kind of laborsaving, high-effect loader braking system self-draining arrangement of in time water that accumulates in the gas circuit being discharged.
The purpose of this utility model is achieved in that by valve body, valve gap, leather cup, strainer, spring, guide peg to be formed, there is strainer on the top of valve body, on the valve seals frame valve seals is arranged, leather cup bottom in the valve body on the leather cup frame is a cone, the conical surface of contact valve gap has spring, guide peg to pass valve gap and leather cup around the leather cup, the valve gap upper end is with the valve bonnet seal circle, and there is collar the lower end.
The operating principle of this valve is: when loader was implemented braking, the gas volume in the braking system gas circuit can expand rapidly, and according to the Moore's Law of gas, the pressure of gas can reduce; Can cause the gas pressure at these valve core two ends unequal like this, spool can move and opens and discharge water under the effect of two ends gas differential pressure to the low end of air pressure, and when the gas pressure at spool two ends was in balance, spool can be closed again automatically.
Because the utility model adopts said structure, when fluctuating in the scope of braking pressure at 30Kpa～100Kpa, leather cup is fast moving up and down, thereby realize the open and close of valve, this device is laborsaving, high-effect in time discharges the water that accumulates in the gas circuit, prevent the too many and corrosion braking member of the hydrogenesis in the braking system gas circuit, guaranteed the sensitivity and the reliability of loader braking.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is vertical profile of the present utility model and structure.Fig. 2 is the A-A sectional drawing of Fig. 1.
1 strainer, 2 valve seals, 3 valve seals framves, 4 valve bodies, 5 leather cups, 6 leather cup framves, 7 springs, 8 valve bonnet seal circles, 9 collars, 10 valve gaps, 11 guide pegs among the figure.
The specific embodiment
Embodiment: form by valve body 4, valve gap 10, leather cup 5, strainer 1, spring 7, guide peg 11, there is strainer 1 on the top of valve body 4, valve seals 2 is arranged on the valve seals frame 3, leather cup 5 bottoms in the valve body 4 on the leather cup frame 6 are cone, the conical surface of contact valve gap 10 has spring 7, guide peg 11 to pass valve gap 10 and leather cup 5 around the leather cup 5, valve gap 4 upper ends are with valve bonnet seal circle 8, and there is collar 9 lower end.
In loader braking system, the utility model valve is contained in minimum point in the loader braking system gas road, guarantee that the water in the gas circuit can both be pooled to the mounting points place of this valve under the effect of gravity.
Under on-position not, leather cup 5 is in equilibrium state under the effect of the gas in the gas in B chamber, C chamber, spring 7, the conical surface of leather cup 5 bottoms and the conical surface seal on the valve gap 10, and the water in the gas circuit is pooled in the B chamber of valve by strainer 1.
When braking, the instantaneous reduction of air pressure meeting in B chamber, the middle part of leather cup 5 can upwards be heaved rapidly, drive guide peg 11 and move up, the conical surface of leather cup 5 lower ends can leave the conical surface of valve gap 10, and valve port is in opening, the gas in C chamber is can rapid blow off valve external and the gas pressure in C chamber is reduced rapidly, leather cup 5 can drive guide peg 11 and move down under the effect of B chamber gas pressure, the conical surface of leather cup 5 lower ends is got back to again on the conical surface of valve gap 10 like this, and valve port is in closure state again.
After the valve port closure in a flash, the gas pressure in C chamber is also far below the gas pressure in B chamber, leather cup 5 can continue to move down under the effect of B chamber gas pressure and the B chamber is communicated with the C chamber, gas in the B chamber enters the C chamber, water in the B chamber also and then enters the C chamber simultaneously, when leather cup 5 was in equilibrium state once more under the effect of the gas in the gas in B chamber, C chamber, spring 7, the gas in the B chamber no longer entered the C chamber, and the water in the B chamber also no longer and then enters the C chamber simultaneously.
When braking once more, the action above leather cup 5 can repeat, the water that enters in the C chamber can be discharged by the cone valve jaw on the valve gap 10.
Ceaselessly braking, this valve will ceaselessly discharge water, thereby in time the water in the braking system gas circuit is discharged.
