Abstract
The utility model relates to a hydraulic oil cylinder part, in particular to a vent valve for a hydraulic oil cylinder, which mainly solves the technical problem that an oil cylinder for a lifting platform in the prior art is not provided with the vent valve, accordingly causes large air pressure in the hydraulic cylinder and easily causes safety accidents. The vent valve for the hydraulic oil cylinder comprises a vent valve body (1) and is characterized in that one end of the vent valve body (1) is provided with a threaded head (2), the other end of the vent valve body (1) is provided with a tip portion (3), a main air channel (4) axially penetrates through the inside of the vent valve body, an inclined plane is arranged between the vent valve body and the tip portion, the main air channel is communicated with an obliquely-arranged branch air channel (5), and an opening of the outer end of the branch air channel is located on the inclined plane.
Description
Technical field
The utility model relates to a kind of hydraulic jack component, especially relates to a kind of hydraulic jack and uses outlet valve.
Background technique
Raising platform is broad-spectrum high-lift operation special device.Its mechanical structure has higher steadiness after raising platform is hoisted, and roomy working platform and advantages of high bearing capacity make high-lift operation wider, and is fit to many people operations simultaneously.Existing raising platform can cause the oil hydraulic cylinder internal air pressure bigger with the outlet valve that do not have of oil cylinder, causes security incident easily.
The model utility content
The utility model provides a kind of hydraulic jack and uses outlet valve, and it mainly is to solve the do not have outlet valve of existing in prior technology raising platform with oil cylinder, can cause the oil hydraulic cylinder internal air pressure bigger, causes the technical problem of security incident etc. easily.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of hydraulic jack of the utility model is used outlet valve; Comprise exhaust valve, described exhaust valve one end is provided with thread head, and the other end is provided with the tip; The inner shaft of exhaust valve is to being penetrated with main airway; Be provided with the inclined-plane between exhaust valve and the tip, main airway is communicated with the branch airway of oblique setting, and the branch airway outer end opening is on the inclined-plane.
As preferably, the taper angle of described tip is 60 °.
Therefore, the utility model is provided with outlet valve on the cylinder body of oil cylinder, and a plurality of air flues are set on the outlet valve, can reduce the air pressure in the oil hydraulic cylinder, avoids causing security incident, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of hydraulic jack of this example is used outlet valve, like Fig. 1, comprises exhaust valve 1, and exhaust valve one end is provided with thread head 2, and the other end is provided with tip 3, and the taper angle of tip is 60 °.The inner shaft of exhaust valve is provided with the inclined-plane to being penetrated with main airway 4 between exhaust valve and the tip, and main airway is communicated with the branch airway 5 of oblique setting, and the branch airway outer end opening is on the inclined-plane.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
Claims (2)
1. a hydraulic jack is used outlet valve; Comprise exhaust valve (1), it is characterized in that described exhaust valve (1) one end is provided with thread head (2), the other end is provided with tip (3); The inner shaft of exhaust valve is to being penetrated with main airway (4); Be provided with the inclined-plane between exhaust valve and the tip, main airway is communicated with the branch airway (5) of oblique setting, and the branch airway outer end opening is on the inclined-plane.
2. a kind of hydraulic jack according to claim 1 is used outlet valve, and the taper angle that it is characterized in that described tip (3) is 60 °.
