Abstract
The utility model discloses an all-weather pneumatic manual conversion mechanism, which comprises a support body arranged in a valve body, wherein a driven big gear and a bearing top seat are arranged on the upper end of the support body, a drive small gear which is engaged with the driven big gear is arranged on the driven big gear, a hand wheel is connected on the outer portion of the drive small gear, a protective cover is arranged on the valve body, and the outer portions of the driven big gear, the bearing top seat and the drive small gear are covered by the protective cover at the same time. The all-weather pneumatic manual conversion mechanism uses the protective cover to seal and protect the drive small gear, the driven big gear and the bearing top seat, thereby enabling gas in bad working conditions such as ash and the like to be difficult to enter, protecting a pneumatic manual conversion mechanism to normally operate, prolonging life of the pneumatic manual conversion mechanism, enabling a pneumatic valve to be used in all weather and bad working condition environment for long time, and guaranteeing safety when operating manually. The all-weather pneumatic manual conversion mechanism can be widely applied for pneumatic valves and the like such as pneumatic gate valves and pneumatic orbit ball valves.
Description
Technical field
The utility model relates to a kind of valve field, especially a kind of round-the-clock Pneumatic and manual switching mechanism.
Background technique
In valve field, the switching mechanism that need use Pneumatic and manual in the manual valve of pneumatic bands such as some Pneumatic gate valves, pneumatic track ball valve.Pneumatic and manual switching mechanism in existing is made up of parts such as bearing footstock, driver pinion, passive gearwheel, supports.Reach in the open under the operating mode harsh conditions; Pneumatic and manual switching mechanism in existing is exposed outside because of long-term; That causes driver pinion, passive gearwheel etc. gathers grieshoch and rust corrosion, and the time one is long, light then increased the frictional force between the driver pinion and passive gearwheel when manual; Heavy then seriously influenced the operation of man-operated mechanism, and possibly make it to lose efficacy.And, because the potential safety hazard of the exposure of gear when having increased manually-operable.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned existing technology, and a kind of round-the-clock Pneumatic and manual switching mechanism is provided, and prevents that the internal mechanism of valve from gathering grieshoch and rust corrosion.
The utility model solves the technological scheme that its technical problem adopts: this round-the-clock Pneumatic and manual switching mechanism; Comprise the support of being located in the valve body; The upper end of support is provided with passive gearwheel, bearing footstock, and wherein passive gearwheel is provided with the driver pinion that is meshed with it, and driver pinion is externally connected with handwheel; Valve body is provided with protective housing, and this protective housing covers the outside of passive gearwheel, bearing footstock and driver pinion simultaneously.Protective housing avoid on the valve parts because of exposed cause outside gather grieshoch and rust corrosion, thereby guarantee that the operation between each parts is smooth and easy.And the safety when effectively having guaranteed manually-operable.
On valve body, the two ends of pole are provided with the fastening piece that is connected on the valve body to protective housing through a pair of strut fixation.This is simple in structure, fixation.
The effect that the utility model is useful is: the utility model adopts protective housing that driver pinion, passive gearwheel and bearing footstock are done sealing protection; Make that the abominable gas of operating mode such as grieshoch is difficult to get into; Thereby protected the normal operation of Pneumatic and manual switching mechanism; Prolong the life-span of Pneumatic and manual switching mechanism, made pneumatic valve round-the-clockly under the operating mode rugged environment, to use for a long time.And the safety when having guaranteed manually-operable.This round-the-clock Pneumatic and manual switching mechanism can be widely used in the pneumatic valves such as Pneumatic gate valve, pneumatic track ball valve.
Description of drawings
Fig. 1 is the structural representation of Pneumatic and manual switching mechanism in the existing technology;
Fig. 2 is the structural representation of the utility model.
Description of reference numerals: support 1, passive gearwheel 2, driver pinion 3, bearing footstock 4, handwheel 5, valve body 6, protective housing 7, pole 8, fastening piece 9.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: this round-the-clock Pneumatic and manual switching mechanism; Comprise the support of being located in the valve body 61; The upper end of support 1 is provided with passive gearwheel 2, bearing footstock 4, and wherein passive gearwheel 2 is provided with the driver pinion 3 that is meshed with it, and driver pinion 3 is externally connected with handwheel 5; Valve body 6 is provided with protective housing 7, and this protective housing 7 covers the outside of passive gearwheel 2, bearing footstock 4 and driver pinion 3 simultaneously.Protective housing 7 is fixed on the valve body 6 through a pair of pole 8, and the two ends of pole 8 are provided with the fastening piece 9 that is connected on the valve body 6.
The utility model adopts protective housing that driver pinion 3, passive gearwheel 2 and bearing footstock 4 are done sealing protection; Make that the abominable gas of operating mode such as grieshoch is difficult to get into; Thereby protected the normal operation of Pneumatic and manual switching mechanism; Prolong the life-span of Pneumatic and manual switching mechanism, made pneumatic valve round-the-clockly under the operating mode rugged environment, to use for a long time.And the safety when having guaranteed operation.This round-the-clock Pneumatic and manual switching mechanism can be widely used in the pneumatic valves such as Pneumatic gate valve, pneumatic track ball valve.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
