Abstract
The utility model relates to a breather valve for a gear case, which is applied to high-speed gear cases and oil tanks. A lubricating oil filter screen is fixedly arranged on a housing of the breather valve, an upper cover is fixedly arranged at the upper end of the housing of the breather valve, and a breathing hole is formed on the side wall of the upper cover; at least two baffle plates are welded on the inner wall of the housing of the breather valve, and the circular arc edges of the baffle plates are welded on the inner wall of the housing of the breather valve; and two adjacent baffle plates are welded on the inner wall of the housing of the breather valve in a staggered manner. The breather valve has the effects that the baffle plates with different angles are arranged in the breather valve, thus the flow rate of steam of lubricating oil can be slowed down, and the steam of the lubricating oil is easy to be condensed into liquid-state lubricating oil during collision. The lubricating oil filter screen is arranged at the upper parts of the baffle plates of the breather valve, so that the lubricating oil can be effectively filtered and the normal pressure in the gear case can be kept. When the lubricating oil filter screen needs to be replaced in normal times, only a gland bush needs to be unscrewed. The breather valve has the advantages of simple structure, convenience in manufacturing, convenience and quickness in use and maintenance and capability of preventing the lubricating oil from running away.
Description
Technical field
The utility model relates to machinery manufacturing technology field, and particularly a kind of inhalation valve of using of high-speed gear box and fuel tank relies on inhalation valve inner filtration net and the effective filtering lubricant oil steam of deflection plate, and avoiding lubricant oil to run decreasing and on machinery equipment, often drip expires greasy dirt.
Background technique
At present, lubricant oil is housed in the high-speed gear box, lubricant oil is used for oilgear.Because gear be full of lubricant oil steam in the gear-box, and pressure is prone to take lubricant oil steam out of gear-box in the gear-box running up frictional heat and produce pneumaticly a little more than external atmosphere pressure.Existing inhalation valve only depends on individual layer or double-layer filtering net filtering lubricant oil steam, and effectively filtering lubricant oil steam causes lubricant oil to run out of speed reducer, on machinery equipment, often drips full greasy dirt.
The model utility content
The purpose of the utility model is: provide a kind of gear-box to use inhalation valve, be fixed on the loam cake top of gear-box, effectively filtering lubricant oil steam reduces lubricant oil and runs out of speed reducer.
The technological scheme that the utility model adopts is: gear-box is used inhalation valve, comprises inhalation valve housing, loam cake, deflection plate and lubrication oil filtration net.In columnar inhalation valve housing lower end connecting thread is arranged, be fixed with the lubrication oil filtration net at the inhalation valve housing, screw thread is fixed with loam cake in the upper end of inhalation valve housing, on the sidewall of loam cake spiracle is arranged; It is characterized in that on the inhalation valve inner walls, be welded with at least two deflection plates, described deflection plate is the steel plate of circular arc, and a side of steel plate is a straight flange; The circular arc side weld of deflection plate is connected on the inhalation valve inner walls, between the straight flange of deflection plate and the inhalation valve inner walls passage is arranged; Two adjacent deflection plate zigzag welds are connected on the inwall of inhalation valve housing.
Described deflection plate is downward-sloping, and the acute angle angle of deflection plate and inhalation valve housing center line is between 20～40 degree.
Screw thread through inhalation valve housing lower end is fixed on gear-box on the gear-box with inhalation valve and covers.Lubricant oil steam at first impacts deflection plate after getting into the inhalation valve housing, through a deflection plate time, changes a flow direction, and reduces flow velocity.Lubricant oil steam in the high-speed gear box reduces through the deflection plate flow velocity, the lubrication oil filtration net can reach effective filtration.
The beneficial effect of the utility model: the utility model gear-box is used inhalation valve, in be provided with the deflection plate of two different amount, can slow down the flow velocity of lubricant oil steam, and lubricant oil steam also condenses into liquid lubricant oil easily in collision.The lubrication oil filtration net is arranged at the top of inhalation valve deflection plate, and effectively filtering lubricant oil, and maintenance gear-box internal pressure is normal.Change the cleaning lubricating oil strainer at ordinary times and also only need back out gland.Simple in structure, easy to make, O&M is also very convenient, reduces lubricant oil and runs out of.
Description of drawings
Fig. 1 is that the utility model gear-box is with inhalation valve structural profile schematic representation.
Among the figure, 1-inhalation valve housing, 2-loam cake, 3-deflection plate, 4-connecting thread, 5-spiracle, 6-lubrication oil filtration net.
Embodiment
