Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
See Fig. 1, a kind of porous plug of the present utility model, comprises the cock body 1 that inside is formed with receiving cavity 11, and receiving cavity 11 and cock body 1 are all preferably rotary structure.Screw thread 12 is formed with to be connected with gearbox casing at cock body 1 lower end outer wall, cock body 1 lower end inner wall is formed with circular groove, the jump ring 3 being provided with grease baffle 2 in circular groove and grease baffle 2 is compressed, grease baffle 2 is preferably evenly distributed with the mesh-structured of some small through hole, facilitate gas smoothly by stopping that other solid particles etc. enter in receiving cavity 11 simultaneously, hot gas in gearbox enters in the receiving cavity 11 of cock body 1 from grease baffle 2, realizes the final Exhaust Gas of Oil-gas Separation.
Prevent fluid from going out with gas permeation in order to ensure smooth gas discharge, a multilayer inserted sheet assembly is provided with in receiving cavity 11, as shown in Figure 1, multilayer inserted sheet assembly comprises a circular columns 4 and multiple dividing plate 5, and dividing plate 5 misplaces and is installed in circular columns 4 and is connected with receiving cavity 11 sidewall.So, the S type labyrinth structure that the dividing plate 5 shifted to install just makes exhaust passage become to be similar in Fig. 1 shown in dotted arrow, can lengthen the length of porous plug passage, under Action of Gravity Field, secondary carries out Oil-gas Separation, fluid is stoped in case, effectively stops fluid seepage.As a kind of concrete structure, multilayer inserted sheet assembly comprises parallel 5 dividing plates 5 shifted to install equally spacedly, circular columns 4 is formed with the mounting groove for being connected with dividing plate 5, be interference fit between each dividing plate 5 and receiving cavity 11, a step 13 is formed in receiving cavity 11, the dividing plate 5 of bottom is connected on step 13, this makes it possible to multilayer inserted sheet component integration to install and be arranged in receiving cavity 11, and installation process is extremely simple.
As shown in Figure 1, be formed with multiple breach 14 in the upper, open end of cock body 1 and above cock body 1, be provided with a cap 6, some gas-permeable channels 7 are formed between the inner circle wall of cap 6 and cock body 1 outer wall, like this, discharge after breach 14 enters gas-permeable channels 7 until exhaust body, composition graphs 1, the discharge direction of gas is downward, therefore avoid on traditional porous plug and to fall into problem in porous plug from top because offering foreign matter that air hole causes, effectively prevent the blocking phenomenon of conventional gearbox.Further, the quantity of breach 14 is 4 (Fig. 1 is sectional view, illustrate only wherein two), and this breach 14 is generally processed by milling machine.As a class concrete structure, the perisporium of cap 6 has joint 62 and ventilation part 63, as shown in Figure 1, joint 62 is close to cock body 1 outer wall and is connected with cock body 1, leave the gas-permeable channels 7 that supplied gas is discharged between ventilation part 63 and cock body 1 outer wall, discharge after breach 14 enters gas-permeable channels 7 until exhaust body.Preferably, the sectional shape of cap 6 perisporium is petal, also can be other distressed structures, as long as ensure that cap 6 and cock body 1 realize being connected to leave again gas-permeable channels 7 simultaneously, the preferred amount of gas-permeable channels 7 is 8.
In addition, conveniently connect cap 6, in cock body 1 upper end, outer wall forms an annular slot 15, and cap 6 is riveted in annular slot 15, and one of them riveting point 61 as shown in Figure 1.
To sum up, porous plug compact structure of the present utility model is attractive in appearance, smooth gas discharge, achieves secondary oil gas and is separated, effectively stop fluid seepage, can prevent extraneous foreign matter from entering simultaneously, solve leakage of oil and the blocking phenomenon of conventional gearbox.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
