Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1-3, the vent valve of a kind of mode of execution of the utility model comprises valve body 1, and said valve body 1 is provided with vent 2, and wherein, the inwall of said vent 2 is provided with uneven structure.
Said uneven structure can be arranged on the screw thread 3 on vent 2 inwalls.Also can comprise a plurality of annular grooves of arranging along the axis of vent 24 that are arranged on vent 2 inwalls, the inwall between annular groove 4 and the adjacent annular groove 4 constitutes described uneven structure.
Said vent valve also comprises bonnet 5, spring 6 and cover plate 7; Said bonnet 5 is installed in an end of valve body 1; One end of said vent 2, spring 6 and cover plate 7 all are positioned at bonnet 5, are provided with the space that supplies air turnover bonnet 5 between valve body 1 and the bonnet 5, and said cover plate 7 is arranged on an end of vent 2 and covers vent 2; One end of said spring 6 and bonnet 5 butts, the other end of said spring 6 and cover plate 7 butts and cover plate 7 applied the pretension effect to vent 2 directions.Spring 6 is a pressure spring.
In this mode of execution, described up and down with being as the criterion up and down among Fig. 1.
Said valve body 1 is a jatharapanvartanasana, and said vent 2 is the ladder circular hole, and the ladder circular hole comprises big hole and the small sircle hole that is positioned at the big hole top; Said screw thread 3 or annular groove 4 are arranged on the small sircle hole; 5 one-tenth inverted round cup shapes of said bonnet, cover plate 7 are positioned at the top of small sircle hole and seal the upper end of small sircle hole, and spring 6 is positioned at the top of cover plate 7; The two ends of spring 6 respectively with the upper bottom portion butt of cover plate 7 and bonnet 5,6 pairs of bonnets of spring 5 produce effects upwards.The upper end of said valve body 1 is provided with the first radially outwards outstanding annular protuberance 8, and the lower end of bonnet 5 is provided with a plurality of inwardly recessed recess 9, and a plurality of recess 9 distribute along the circumferencial direction of bonnet 5; The first annular protuberance 8 is positioned at bonnet 5, and recess 9 is positioned at the first annular protuberance, 8 belows, along axially seeing of valve body 1; The recess 9 and the first annular protuberance 8 are overlapping; Simultaneously, the lower edge of the first annular protuberance 8 and recess 9 butts stop bonnet 5 to move upward with this.Do not contact between the part that the lower end of bonnet 5 is not provided with recess 9 and the first annular protuberance 8, but certain clearance is arranged, said gap is the space of above-mentioned confession air turnover bonnet 5.
The mounting structure of the vent valve of a kind of mode of execution of the utility model; As shown in Figure 4; Comprise casing 10 and above-mentioned vent valve, said casing 10 is provided with mounting hole 12, said valve body 1 be fixedly mounted on the said mounting hole 12 and valve body 1 outer wall and mounting hole 12 inwalls between seal and contact; Said bonnet 5 is positioned at outside the casing 10, and the end away from valve gap of said vent 2 is positioned at casing 10.
To contact in order making to seal between valve body 1 outer wall and mounting hole 12 inwalls, can to make interference fit between valve body 1 and the mounting hole 12, also can between valve body 1 and mounting hole 12, be coated with the sealer that seals.
The working principle of the vent valve of this mode of execution is described below.When this vent valve is installed in 10 last times of casing; Air in the casing 10 enter into vent 2, when casing 10 in the pressure of air hour, owing to spring 6 holddown plates 7; The upper end in cover plate 7 closed vent holes 2, so the air in the casing 10 can not flow out from vent valve.The pressure of air increases to the time spent of doing that can overcome spring 6 in casing 10, and air backs down cover plate 7, and air enters in the bonnet 5, and from said gap, flows out to outside the vent valve, promptly flows out to outside the casing 10.When air flow through from vent 2, because the inwall of vent 2 is provided with screw thread 3 or other uneven structure, rough inwall had increased the obstruction of fluid and suction-operated, has reduced the amount of the fluid of being taken out of by air, has reduced leakage of oil.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
