Description
Technical field
The present invention relates to vacuum drying oven technical field, be specifically related to a kind of manual vacuum stove.
Background technology
Namely vacuum drying oven utilizes vacuum system to be discharged by moieties in furnace chamber in this particular space of furnace chamber, makes pressure in furnace chamber be less than a standard atmospheric pressure, stove cavity space thus realize vacuum state, Here it is vacuum drying oven.The vacuum system of present use usually by elements such as vavuum pump, vacuum measuring device, vacuum valves through meticulously assembling.Because present vavuum pump carrys out the time to vacuumizing in stove as power, so just require, vacuum drying oven just can must use when there being electric power, causes certain limitation like this to the use of vacuum drying oven.And the negative pressure value in vacuum drying oven is decided by vavuum pump, be inconvenient to regulate.
Summary of the invention
For above problem, the invention provides a kind of manual mode that uses and control, the convenient manual vacuum stove regulated.
The technical solution adopted for the present invention to solve the technical problems is: this manual vacuum stove comprises body of heater, pump bowl, piston; Described piston slidable sealing is assemblied in described pump bowl, front end manually main valve control and the break-make in body of heater of described pump bowl; Flanged pipe is communicated with in body of heater, and the rear end of described pump bowl is assembled with described body of heater mutually by fixing screw mandrel; The inner side axial limiting of described pump bowl rear end is equipped with large bevel gear, described large bevel gear is connected with described screw mandrel coaxial threaded, described large bevel gear is connected with cone pinion by gear structure, and fixed axis and the large bevel gear axle vertical-horizontal of described cone pinion export.The fixed axis end of described cone pinion is equipped with crank, and the front end of described pump bowl is also designed with manually secondary valve and controls the venthole of break-make.
As preferably, described cone pinion diameter is less than large bevel gear diameter.
As preferably, described screw mandrel is processed with the through hole laterally run through.
Beneficial effect of the present invention is: this manual vacuum stove uses Non-follow control, before vacuumizing body of heater, is adjusted to by piston inside described pump bowl, is closed by manual for manual main valve open secondary valve.When needing to vacuumize, open manual main valve, body of heater is communicated with pump bowl, rotate shake crank, drive cone pinion and large bevel gear to rotate, when large bevel gear rotates, can not move forward and backward because described large bevel gear is axially limited, the screw mandrel that such and described large bevel gear is threaded, move backward and piston pulled, vacuumizing completing in body of heater, then manual main valve being closed, body of heater is closed, keeps furnace pressure.This manual vacuum stove is completed by manual action vacuumize completely, and structure is simple, easy to implement.
Accompanying drawing explanation
Fig. 1 is the structural representation in manual vacuum stove front.
Fig. 2 is the structural representation that pump bowl overlooks direction.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described:
As shown in embodiment in Fig. 1 and Fig. 2, this manual vacuum stove comprises body of heater 1, pump bowl 2, piston 3; Described body of heater 1 is according to need of production specific design.Described piston 3 slidable sealing is assemblied in described pump bowl 2, front end manually main valve 4 control and the break-make in body of heater 1 of described pump bowl 2, and the rear end of described pump bowl 2 is assembled with described body of heater 1 phase by fixing screw mandrel 5; The inner side axial limiting of described pump bowl 2 rear end is equipped with large bevel gear 6, described large bevel gear 6 is connected with described screw mandrel 5 coaxial threaded, and described screw mandrel 5 is fixed with described piston 3, cannot axial-rotation, described large bevel gear 6 can axial-rotation, cannot before and after rotate; Described large bevel gear 6 is connected with cone pinion 7 by gear structure, and fixed axis and the large bevel gear 6 axle vertical-horizontal of described cone pinion 7 export little.The fixed axis end of described cone pinion 7 is equipped with crank 8, and the front end of described pump bowl 2 is also designed with manually secondary valve 9 and controls the venthole of break-make.
This manual vacuum stove uses Non-follow control, before vacuumizing body of heater 1, is adjusted to by piston 3 inside described pump bowl 2, manual main valve 4 is opened manual secondary valve 9 and closes.When needing to vacuumize, open manual main valve 4, body of heater 1 is communicated with pump bowl 2, rotate shake crank 8, drive cone pinion 7 and large bevel gear 6 to rotate, when large bevel gear 6 rotates, can not move forward and backward because described large bevel gear 6 is axially limited, the screw mandrel 5 that such and described large bevel gear 6 is threaded, move backward and piston 3 pulled, vacuumizing completing in body of heater 1, then manual main valve 4 being closed, body of heater 1 is closed, keeps furnace pressure.If need to continue to vacuumize, opened by manual secondary valve 9, be adjusted to by piston 3 inside described pump bowl 2, then closed by manual secondary valve 9, manual main valve 4 is opened, and repeats said process.This manual vacuum stove is completed by manual action vacuumize completely, and structure is simple, easy to implement.
As shown in Figure 2, described cone pinion 7 diameter is less than large bevel gear 6 diameter.The shake that such needs are less just can shake described crank 8.Use operation more light.
Described screw mandrel 5 is processed with the through hole 51 laterally run through.Like this when needs carry out spacing to screw mandrel 5, spacer pin can be inserted in screw mandrel 5.
