Description
Technical field
The present invention relates to pneumatic tool field, particularly relate to a kind of integral type control valve.
Background technology
Pneumatic impact wrench operationally, needs to use the components such as air motor, reversal valve, control valve.In prior art, most of pneumatic tool not by air motor front end-plate and other parts in conjunction with as a whole, the complexity of assembling can be caused like this.Even if there is the situation all correlated parts being integrated into an overall structure and using, but its commutation to turn round be adopt the form of stirring up and down, and commutation is turned round with the position of trigger very near, can cause operational inconvenience like this.
In use, for solving the complexity of assembling and how effectively realizing the appropriate design of reversing mode and trigger position, the present invention adopts a kind of new structure to make improvements, with solve parts in prior art scattered be arranged in tool interior complexity and commutation turn round the inconvenience with trigger operated.
Summary of the invention
The object of the invention is to improve the annexation between each parts of existing control valve, provide a kind of integral type control valve, the use of this structure achieves the unitary design of each parts of control valve, makes assembling simpler, effective; Simultaneously by commutation turn round be designed to rack and pinion drive button type structure, thus achieve commutation turn round the convenience with trigger operated.
The object of the invention is to be achieved by following technical proposals:
Integral type control valve, comprise a motor front end-plate, one valve assembly, this valve assembly is fixed on described motor front end-plate by a resilient key II, described valve assembly comprises a control valve, one reversal valve, one regulates button, one spring I, one copper sheathing, one trigger bar, one trigger button, described trigger bar is through control valve, reversal valve, regulate button, spring I, copper sheathing and trigger button are fixed together, described trigger bar, trigger button has groove, and adopt a resilient key I to be fixed together, the centre of described reversal valve has an endoporus, described control valve runs through the endoporus of described reversal valve and and adopts a flat filament to link together between adjustment button.
Preferably, described control valve is provided with an O type circle I, and this O type circle I is located at described control valve and regulates between button.
Preferably, described reversal valve is provided with an O type circle II, and this O type circle II is located between described control valve and reversal valve.
Operation principle of the present invention is: in the present invention, the position being changed reversal valve by gear is turned round in commutation, thus changes the positive and negative rotation direction that the airflow direction entering cylinder finally changes motor.Control valve is circumferentially provided with the hole varied in size, and different apertures determines the size of the air-flow entering motor.Regulate button to be connected with control valve, rotate adjustment button thus the power of governor motor is carried out in the effective aperture of change control valve.Because the choose reasonable of reversing mode is turned round in its integral design and commutation, drastically increase convenience and the accuracy of assembling and operation.
Beneficial effect: related components is integrated in an entirety by integral type control valve of the present invention effectively, achieves modularized design, simplifies assembling process; And because its integrated design makes rigging error less, assembling better effects if.The structure being designed to pinion and-rack is turned round in commutation in addition, effectively can avoid and trigger interference capability operationally, achieve the convenience of operation.The present invention is applicable to the pneumatic tool structure field that pneumatic impact wrench etc. needs to use the components such as air motor, reversal valve, control valve.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiments, the invention will be further described.
Embodiment:
As Figure 1-3, motor front end-plate 6, as a part for motor, is used for fixing valve assembly, and valve assembly is fixed on motor front end-plate 6 by resilient key II 14.Valve assembly comprises control valve 3, reversal valve 2, regulates button 4, spring I 7, copper sheathing 5, trigger bar 15, trigger button 8.Commutation is turned round 1 position changing reversal valve 2 by gear and is changed the airflow direction that enters cylinder thus the positive and negative rotation direction changing motor, and the position of reversal valve 2 determines to enter the airflow direction of cylinder thus affects the positive and negative rotation direction of motor.Control valve 3 circumferentially has the hole of different size, and different apertures determines the size entering the air-flow of motor.Copper sheathing 5 is used for supporting trigger bar 15, and trigger bar 15 axially moves in copper sheathing 5.The effect of spring I 7, spring II 13 is that trigger is resetted.
Trigger bar 15 is fixed together with trigger button 8 through control valve 3, reversal valve 2, adjustment button 4, spring I 7, copper sheathing 5, trigger bar 15, trigger button 8 have groove, and adopting resilient key I 9 to be fixed together, trigger button 8 is backed down draught damper by trigger bar 15 and is carried out starter.The centre of reversal valve 2 has an endoporus, and control valve 3 runs through the endoporus of reversal valve 2 and and adopts a flat filament to link together between adjustment button 4.Rotate and regulate button 4, the size in aperture on control valve 3 can be changed, thus change the size entering the air-flow of motor.Steel ball 12 makes reversal valve 2 have forward and reverse two static stalls by spring II 13, makes adjustment button 4 have three regulation stalls.
Control valve 3 is provided with an O type circle I 10, and this O type circle I 10 is located at control valve 3 and regulates between button 4, for sealing air-flow.Reversal valve 2 is provided with an O type circle II 11, and this O type circle II 11 is located between control valve 3 and reversal valve 2, for sealing air-flow.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
