Abstract
The utility model relates to a novel ventilation device, which comprises a dustproof cover, a spring, a cover plate and a ventilation plug. The ventilation plug is connected on a base of a container or a hydraulic system through threads, the cover plate is arranged in a groove of the ventilation plug, the spring is arranged on the cover plate, the other end of the spring props against the dustproof cover, and an opening of the dustproof cover is clamped on the ventilation plug through stamping deformation. The ventilation plug is provided with an axial ventilation blind hole and a transverse ventilation hole, a cone at the lower end of the ventilation plug is contacted with the vertex angle of a conical hole on the base, the threads of the ventilation plug can extrude the base material for plastic deformation when being screwed, thereby forming a sealing surface, and large pre-tightening force can be produced at the threads under force generated by two conical surfaces during extrusion so as to effectively prevent the threads from being loosened and automatically lock the threads. The utility model has simple structure and good ventilation and sealing effect, and is easy to process.
Description
Technical field
The utility model relates to the venting gas appliance that is contained on container and the hydraulic system.
Background technique
Some containers and hydraulic system are in order to discharge gas wherein, usually load onto venting gas appliance at container or system's uppermost position, the normal venting gas appliance that adopts is to adorn a through hole that has internal thread on base, and the plug screw of packing in the hole is backed out plug screw when exhaust.Also some adds seal ring in the plug screw bottom, strengthens sealing effect.This venting gas appliance the gap occurs because of wearing and tearing between screw thread easily and becomes flexible after using certain hour, the influence sealing, and easily polluted by dust.
Summary of the invention
The purpose of this utility model provides a kind of processing of being convenient to, and sealing, anti-loosing effect is good and have the novel exhaust device of dust reduction capability.
The purpose of this utility model is achieved in that venting gas appliance comprises dust-proof cover, spring, cover plate, venting plug composition.Venting plug is by being threaded on container or the hydraulic system base, and cover plate is positioned in the groove of venting plug, lays spring on the cover plate, and the spring the other end withstands on the dust-proof cover, and dust-proof cover opening punching press distortion is stuck on the venting plug.Axial ventilation blind hole and horizontal communication hole are arranged on the venting plug, venting plug lower end cone is different with the angle of base taper hole, venting plug lower end cone contacts with base taper hole drift angle, extruding produces plastic deformation to submount material when tightening the venting plug screw thread, form sealing surface, the power that two conical surfaces produce when extruding makes the screw thread place form bigger pretightening force, effectively prevent the loosening of screw thread, the auto lock screw thread.Dust-proof cover on the venting plug prevents that dirt from stopping up exhaust port, and the cover plate spring under prevents that dust etc. from entering exhaust port, and the assurance exhaust port is unimpeded.
The utility model is simple in structure, easy processing, and exhaust and good sealing effect.
Description of drawings
Fig. 1 novel exhaust structure drawing of device
Among the figure: 1. the dust-proof cover 2. springs 3. cover plates 4. venting plug 4-1. blind hole 4-2. horizontal communication hole of axially ventilating
Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention is further described.
As shown in Figure 1: this venting gas appliance is made up of dust-proof cover 1, spring 2, cover plate 3, venting plug 4.On venting plug 4 outer walls screw thread is arranged, the bottom is a cone, and there are axially a ventilation blind hole 4-1 and a horizontal communication hole 4-2 in the centre, and spring 2 is housed in the dust-proof cover 1, and spring is equipped with cover plate 32 times.Behind assembling spring 2 and the cover plate 3,, assemble as a whole with dust-proof cover 1 opening punching press distortion.
Unscrew the screw thread of venting plug 4 when exhaust, venting plug 4 lower cone bodies and base taper hole form the gap, and gas is discharged from the gap, via axial ventilation blind hole 4-1 and horizontal communication hole 4-2, back down spring 2 backs and discharge.After exhaust is finished, tighten the screw thread of venting plug 4, venting plug 4 lower cone body cone angles form sealing surface to the extruding of base taper hole summit, finish sealing.Because the extruding of two conical surfaces produces the pretightening force of screw thread when tightening, and venting plug 4 is played the locking thread effect.Dust-proof cover 1 and spring 2,3 dustproof effect of cover plate.
Claims (1)
