Abstract
The utility model relates to an automatic exhaust protection device of which a main body consists of a hermetic tank body. The automatic exhaust protection device is characterized in that: a cavity of the tank body is provided with a vertical baffle plate; a gap is formed between the baffle plate and the bottom of the cavity of the tank body; the tank body is partitioned into a left cavity and a right cavity by the baffle plate; the side face of the left cavity is provided with an air inlet and a liquid level meter; a floating ball, a linkage device and an exhaust valve are arranged inside the left cavity; the top of the left cavity is provided with an exhaust opening; the bottom of the right cavity is provided with a drain valve; the top of the right cavity is provided with an exhaust opening; when the air pressure inside the air inlet surpasses a design pressure, the liquid level in the left cavity falls, the liquid level of the right cavity rises, the floating ball falls along with the liquid level, the exhaust valve is opened through the linkage device, and the air is exhausted through the exhaust opening; and when the air pressure inside the air inlet is lower than a set value, the liquid level of the left cavity rises, the floating ball rises, the exhaust valve is closed, the exhaust opening is communicated with the atmospheric air, and the drain valve can be used for draining liquid in the protection device.
Description
Technical field
The utility model relates to a kind of self-bleeding fender guard, and especially the self-bleeding mode has adopted the principle of float switch in this device.
Background technology
The large-scale storage tank container in use will have safety device, avoid liquid in the large-scale storage tank container or gas to increase or the malleation brought when reducing and negative pressure to the destruction of container.The mechanical respiration valve gear is commonly used in the large-scale storage tank container, the mechanical type breathing valve is to utilize the container inner pressure difference of the gravity of valve and stored-gas to guarantee the safety of container, but there is the problem of jam and leakage in actual applications in this device, especially this device uses when the noxious gas container, and the leakage of mechanical breather valve will have pollution to environment; When the mechanical breather valve jam, the danger of exploding very easily appears in protected volume.The defective of above-mentioned several parts exists inconvenient operation and potential safety hazard in application.
Chinese patent literature ZL200820224808.8 discloses " a kind of anti-PNPB valve gear ", the hydraulic pressure fluid-tight principle that this device adopts.
Summary of the invention
The purpose of this utility model provides the device of a kind of easy to operate, good airproof performance, safe self-bleeding defencive function.
A kind of self-bleeding fender guard main body is that the leak free tank body is formed, and it is characterized in that described tank inner chamber is provided with a vertical baffle plate and incites somebody to action, and the gap is left in baffle plate and tank inner chamber bottom, and baffle plate is divided into left chamber and right chamber with tank body.Left chamber wherein is communicated with admission port, and sidewall is equipped with liquidometer, and this part inside cavity is equipped with floating ball device, blow off valve, and the top is provided with exhausr port.Bottom, right chamber is provided with sluicing valve, and the top is provided with exhausr port.
A kind of self-bleeding fender guard of the utility model is characterized in that the height by the pressure change liquid level, controls the height of ball float simultaneously, changes the unlatching of blow off valve.
A kind of self-bleeding fender guard of the utility model when it is characterized in that exhaust, is directly discharged from exhausr port, without inside cavity liquid, can not influence the moisture of inside cavity, has guaranteed the precision of device.
