Abstract
The utility model relates to a steel cord drawing mill gear case air-release valve. The steel cord drawing mill gear case air-release valve comprises a valve body and a valve seat, wherein the valve seat is sealed and fixed on an air-release hole of a gear case, the valve body is in threaded connection with the valve seat, the connection position between the valve body and the valve seat is provided with a sealing ring in a sleeved mode, the upper end of the valve body is sealed, the valve body is provided with an inner cavity, the side wall of the valve body is provided with vent holes, the height of the vent holes of the valve body is larger than the height of the oil level inside the gear case, the outer surface of the valve body is in a hexagonal prism structure, the connection position between the valve seat and the valve seat is provided with an annular flange, and the valve seat is a straight pipe in shape or is a L-shaped bending pipe in shape. According to the steel cord drawing mill gear case air-release valve, the valve body is upwards, the vent holes are arranged in the side face, balance of inside and outside air pressure is guaranteed, pressure inside the valve body is not quite high, and therefore lubricating oil inside the gear case does not overflow from the vent holes of the valve body.
Description
Technical field:
The utility model relates to a kind of steel cord drawbench gear-box bleed valve.
Background technique:
In the steel cord production process, drawbench gear-box working load is bigger, and the gear-box inner chamber is full of lubricant oil; The back Yin Wendu that works long hours rises and the volatilization reason; The gear-box internal pressure is bigger, if do not take effective unloading pressure means, fluid can overflow befouling environment along transmission shaft.Though the organization plan that bleed valve is set is arranged on gear-box at present, poor effect mostly, existing gear-box bleed valve often becomes one of channel that lubricant oil leaks, and causes surrounding environment seriously polluted.
Summary of the invention:
The utility model is to overcome deficiency and the defective that existing technology exists, and a kind of steel cord drawbench gear-box bleed valve is provided.
Technological scheme: a kind of steel cord drawbench gear-box bleed valve, comprise valve body and valve seat, valve base sealing is fixed on the gear-box venting aperture; Valve body is threaded with valve seat; And be set with seal ring in the joint, and the sealing of valve body upper end, valve body is provided with inner chamber; Body wall is provided with exhaust port, and the relief opening height of valve body is higher than fuel head in the gear-box.
Said valve outer surface is six prism structures.
Valve body and valve seat joint are provided with annular flange flange.
Valve seat is the straight tube shape or is " L " type bend pipe shape.
The beneficial effect of the utility model: the utility model valve body upwards is provided with exhaust port in the side, guarantees inside and outside air pressure balance, does not have too high pressure in the valve body, so lubricant oil can not overflow from the exhaust port of valve body in the gear-box.Structures such as spring or piston need be set in valve body, simple and practical, effective.Valve body and valve seat combination are used, and valve seat can be arranged to straight tube or bend pipe structure, can guarantee that the valve body exhaust port is higher than gear-box all the time, prevents that lubricant oil from flowing out from exhaust port.
Description of drawings:
Fig. 1 is that the utility model is done cross-sectional view.
Label 1 is a valve body among the figure, and 2 is valve seat, and 3 is seal ring, and 4 is annular flange flange, and 5 is exhaust port, and 6 is gear-box.
Embodiment:
Referring to Fig. 1, this steel cord drawbench gear-box bleed valve comprises valve body 1 and valve seat 2, and valve body 1 is threaded with valve seat 2 and is set with seal ring 3 in the joint.Valve body 1 is provided with annular flange flange 4 with valve seat 2 joints, and seal ring 3 is positioned at annular flange flange 4 downsides.Valve seat 2 can or be " L " type bend pipe shape for the straight tube shape.So no matter the vent hole of gear-box is arranged on its upper surface or side,, valve seat can both make the height of valve body 1 exceed lubricant oil height in the gear-box through being installed.Valve seat 2 sealing and fixing are on gear-box venting aperture, and valve body 1 upper end seals, and valve body is provided with inner chamber, and body wall is provided with exhaust port 5, thereby the valve body inner and outer air pressure is equal, the problem that lubricant oil is forced out the valve body exhaust port can not occur.For the ease of installation and removal, can be six prism structures with valve body 1 outer surface.
