Abstract
The utility model relates to a pneumatic wrench compressed air flow regulating valve, which belongs to components of pneumatic wrenches of pneumatic tools. The regulating valve jointly works with a switching system and a reversing system inside a pneumatic wrench handle, and regulates air flow through regulating holes on the valve, thereby further controlling output torque, meeting the requirements of different working conditions and achieving the purpose of screwing or disassembling bolts. The regulating valve is a stepped cylinder; a regulating handle is arranged at the large end of the regulating valve; the small end of the regulating valve is cylindrical; the regulating holes arranged on a cylinder wall correspond to an air passage inside the handle; and compressed air flow is changed and the torque is controlled by the regulating holes with different diameters, thereby finishing operation tasks. A small section of the regulating valve is installed inside the handle, and a large-end step is clamped to the end surface of the handle and limited by an elastic cylinder. The regulating valve is installed inside the pneumatic wrench handle, and the regulating valve is used for regulating the compressed air flow, thereby controlling the output torque and finishing the work of assembling and disassembling the bolts with different diameters by a pneumatic wrench.
Description
Technical field
The utility model relates to the pneumatic wrench of pneumatic tool class, specifically is pneumatic wrench compressed air require control valve, is the part of pneumatic wrench.
Background technology
At present its compressed air air inflow of pneumatic wrench of using is single changeless, the moment of torsion of pneumatic wrench output also is to immobilize and uncontrollable, tightening or during demounting bolt, can not look diameter of bolt size and adjust moment of torsion, tend to cause because of compressed air require excessive, output torque is excessive and twist into two parts bolt, or, the output torque too small and stubborn not adverse consequences of tight bolt too small because of compressed air require.Limited the range of application of pneumatic wrench, also brought inconvenience in the production.
Summary of the invention
The utility model provides a kind of pneumatic wrench compressed air require control valve of regulating the compressed air charge flow rate at the problem that existing pneumatic wrench exists, and according to the size adjustment air inflow of the diameter of bolt, the control output torque guarantees the pneumatic wrench operate as normal during use.
The technical solution of the utility model is as follows: the utility model is loaded in the pneumatic wrench handle body, in the pneumatic wrench handle body switching system and exchange system are housed also, switching system is by switch, elastic cylindrical pin, push rod, rubber ball, volute spring, sealing ring and air inlet nut are formed, exchange system is made up of commutation valve pocket and reversal valve, pneumatic wrench compressed air require control valve is loaded in the pneumatic wrench handle body, control valve is the cylinder of different-diameter, the hypomere diameter is big, the epimere diameter is little, epimere inserts in the handle body, spacing with elastic cylindrical pin, opposite side is equipped with steel ball, retainer spring, the upper end of epimere is a tubular, is shaped on uniform on the barrel and radial hole different-diameter, these holes are corresponding with the interconnection of gas handling system, and sealing ring is equipped with in the below of tubular section.
The course of work of this control valve: the pneumatic wrench head is installed on handle body top, the air inlet nut of lower end connects compressed air hose, switch is not in closed condition the time spent, gas circuit is obstructed, and operating switch during use pushes push rod downwards, push rod backs down rubber ball, rubber ball compression volute spring, this moment switch opens, compressed air enters handle body internal channel by the air inlet nut, then enter control valve, turn control valve on demand, make the corresponding airway of suitable radial hole, reach required air mass flow, compressed air enters reversal valve through control valve, change airflow direction on demand, make the vane motor that is loaded on the head clockwise or reverse, realize tightening or the purpose of demounting bolt.
The beneficial effects of the utility model are as follows: 1, the hole by four different-diameters on the control valve, regulate the charge flow rate of pneumatic wrench, the control output torque, can select suitable moment of torsion according to the size of the diameter of bolt, tighten smoothly or demounting bolt, bad result under can not occurring twisting into two parts or tear open has not expanded the function of use of pneumatic wrench, has enlarged the range of application of pneumatic wrench; 2, simple in structure, be convenient to processing, the repacking; 3, control valve can be applicable on other pneumatic tools, applied range, and can improve air tool service behaviour.
