The exhaust brake valve with internal respiration structure of the present utility model, its core is the design of servo cylinder, the structure of this servo cylinder is simple, tool has the following advantages: increase dust-proof leather cup and seal ring at the cylinder cap place of servo cylinder, prevent external dust from entering in cylinder, cylinder cap arranges spiracle and exhaust diaphragm, guarantees that the air pressure at cylinder cap place during pistons work discharged to air, can ensure the thrust of push rod; Piston increases a check valve apparatus, and do not have sealing function during low pressure, have sealing function during high pressure, during piston return, on the left of piston, cavity can supplement air pressure from cavity on the right side of piston; Sealing member in dust-proof leather cup and cylinder all adopts the elastomeric material with excellent abrasive resistance and heat-resisting quantity to make.
The principle of work of what this enforcement was novel the have exhaust brake valve of internal respiration structure is as follows:
(1) cylinder body of servo cylinder offers an admission port, and the air pressure of gas circuit acts on piston by admission port, promotes piston and push rod, overcome pull back spring effect and to left movement, push rod band moving valve plate rotates, and realizes the closedown of gas exhaust duct, reaches the effect of energy brake; After the air pressure release of gas circuit, piston and push rod get back to initial position by the application force of pull back spring, realize the unlatching of valve block, brake off.
(2) during energy brake; the effect that piston is subject to gas circuit air pressure starts to left movement; check valve apparatus on piston now plays sealing function; piston and push rod are moved to control position, guarantees leak tightness when normally working, simultaneously when piston moves to control position; on the left of piston, the space of cavity is compressed; air pressure increases, and the air pressure of increase is walked around exhaust diaphragm by the spiracle on cylinder cap and entered air, guarantees piston flexible motion.
(3) during brake off, gas circuit air pressure reduces, piston moves to initial position from control position by the effect of pull back spring, and now on the left of piston, the space of cavity increases, and air pressure reduces, need to suck air from outside, the dust-proof leather cup that cylinder cap is arranged, exhaust diaphragm and seal ring now play sealing function, prevent external dust, impurity etc. from entering cylinder, are provided with dual dustproof construction herein, even if outer field dust-proof leather cup fails, internal layer still has exhaust diaphragm and sealing to enclose dustproof effect; When on the right side of piston, the air pressure of cavity drops to a certain degree; one-way cock moves right under the action of the spring; band dynamic seal ring I moves right simultaneously; passage is opened; depressurization effect; the air pressure of cylinder intake end enters into the left side cavity of piston, prevents cavity on the left of cylinder from producing pull of vacuum, guarantees piston flexible motion.
The principle of work of three kinds of check valve apparatus of the present utility model is as follows:
The first check valve apparatus: when being subject to gas pressure on the right side of check valve, filtering net plays the effect of filtered air, throttling action is played in gap small between one-way cock and piston, and air pressure by gap small between one-way cock and piston, then can only arrive on the left of check valve through passage.Because the tolerance clearance between one-way cock and piston plays throttling action, so pressure on the left of check valve will be less than the pressure on right side, now one-way cock will overcome the power of spring and to left movement, and cut off passage.Seal ring I plays the effect of sealing.During brake off, the pressure on the right side of one-way cock reduces, and the effect that one-way cock is subject to spring moves right, and passage reopens, depressurization effect.
The second check valve apparatus: when being subject to gas pressure on the right side of check valve, filtering net plays the effect of filtered air, and seal ring II plays the effect of sealing, and air pressure can only pass through cutoff port, then arrives on the left of check valve through passage.Due to the effect of cutoff port, so the pressure on the left of check valve will be less than the pressure on right side, now one-way cock will overcome the power of spring to left movement, and cuts off passage.Seal ring I plays sealing function.During brake off, the pressure on the right side of one-way cock reduces, and the effect that one-way cock is subject to spring moves right, and passage reopens, depressurization effect.
The third check valve apparatus: when being subject to gas pressure on the right side of check valve, filtering net plays the effect of filtered air, and orienting sleeve I plays the effect of guiding and throttling, and air pressure by the small gap between orienting sleeve, then can only arrive on the left of check valve through passage.Due to the throttling action of orienting sleeve I, so the pressure on the left of check valve will be less than the pressure on right side, now one-way cock will overcome the power of spring to left movement, and cuts off passage.Seal ring I plays the effect of sealing.During brake off, the pressure on the right side of one-way cock reduces, and one-way cock moves right by the effect of spring, and passage reopens, depressurization effect.
