Technical field
The utility model relates to straight journey line movement valve technology field, is specifically related to a kind of use at three grades of many turning valves of transmission manual driving devices of the line movement valve of many revolution inputs.
Background technique
Line movement valve, can be called linear motion valve again, comprises that parallel gate valve, Wedge gate valve, knife gate valve, pipeline gate valve etc. are various to carry out straight line motion by threaded valve rod on external diameter, the valve that drives valve plate or spool to control gas or fluid.Because line movement valve is commonly used to be connected with gas or the liquid of high pressure, so just needing has good slipper seal between spool and housing, in the time of need to guaranteeing between spool and valve body in off position, seal, in order to guarantee that sealing can make the larger warping force of rotary needs between spool and valve body.Because the transmission efficiency of umbrella gear is higher, line movement valve especially in some gate valves umbrella gear transmission be a kind of relatively normal rotary drive mode of using, but in present technology, single-stage umbrella gear drive valve manual driving device is owing to being subject to the restriction of speed ratio, specified input torque can not be amplified to required torque request, can only rely on the method that strengthens input torque to increase output torque, the umbrella gear manual driving device torque power gain of single-stage driving is limited, development along with Chinese valve industry, large size valve, continuing to bring out of the valve of super sized type valve and hard sealing, particularly want now operation convenience abroad, after maximum input torque is limited, single-stage or twin-stage valve manual driving device, cannot carry out manually-operable to valve.
Summary of the invention
For above problem, it is a kind of easy to use that the utility model provides, three grades of many turning valves of transmission manual driving devices that driving torque is larger.
The utility model solves the technological scheme that its technical problem adopts: these three grades of many turning valves of transmission manual driving devices comprise main casing, transmission housing; Be loaded on primary input axial, one-level driving gear, secondary input shaft, secondary transmission gear in described transmission housing, be loaded on three grades of angular wheel shafts, output bevel gear in described main casing; Described primary input axial, secondary input shaft are the gear shaft that end is processed with gear structure, and described three grades of angular wheel shafts are the angular wheel shaft that end is processed with umbrella gear structure; Described transmission housing is fixed on the side of described main casing; The engagement of described three grades of angular wheel shaft one end and described output bevel gear, the other end passes described main casing and stretches into described transmission housing and coaxially fix with described secondary transmission gear; The gear end engagement of described secondary transmission gear and described secondary input shaft, the other end of described secondary input shaft and described one-level driving gear are coaxially fixing, the gear end engagement of described one-level driving gear and described primary input axial, the other end of described primary input axial stretches out described transmission housing; Described primary input axial end gear diameter is less than described one-level driving gear diameter, and described secondary input shaft end gear diameter is less than described secondary transmission gear diameter, and described three grades of angular wheel shaft end umbrella gear numbers of teeth are less than the described output bevel gear number of teeth.
As preferably, described primary input axial, three grades of angular wheel shafts are by the coaxial rotatable assembling of rolling bearing.
As preferably, in the middle of described output bevel gear axle, be equipped with Stem Mut.
The beneficial effects of the utility model are: this three grades of many turning valves of transmission manual driving devices assemble mutually with valve rod, valve body, and the end of the transmission housing that described primary input axial stretches out is used for assembling mutually with the manual drives element such as handwheel, hand lever; In use, described primary input axial is by manual input torque, by described one-level driving gear, be passed to described secondary input shaft, then by described secondary transmission gear, torque is passed to described three grades of angular wheel shafts, torque is passed to described output bevel gear the most at last, realize three grades of transmissions, by output bevel gear, torque has been transferred to valve rod, and then realized the switch to valve.In the process of three grades of transmissions, the input number of teeth of every one-level is all less than the output number of teeth, and the level of torque level of input expands like this, specified input torque can be amplified to required torque request, this device can be so that the torque of input realizes manually-operable easily, and compact structure is easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of these three grades of many turning valves of transmission manual driving device part sections.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
