A kind of problem of gas explosion, there is provided pneumatic scroll saw with automatic shutoff protection device.
The utility model solves the technical scheme adopted by its technical problem：It is a kind of with automatic shutoff protection device
Pneumatic scroll saw, including nozzle, air motor and installation housing, are installed with inlet pipeline, outlet pipe in the mounting shell body
Road and bucket is suppressed, the branch road formed between the inlet pipeline and the outlet pipeline flows through the rodless cavity for suppressing bucket, institute
State inlet pipeline to be connected with the nozzle, it is described suppress suppress plate, the outer wall for suppressing plate and institute
The inwall laminating for suppressing bucket is stated, and described being suppressed be installed with plate support bar, thick stick be rotatablely equipped with the installation housing
Bar, the support bar are hinged with one end of the lever, are additionally provided with two-way valve, in the two-way valve on the installation housing
Valve rod is hinged with the other end of the lever, and the gas outlet of the two-way valve is connected by pipeline with the air motor.
In order to control the number range of hydraulic pressure, it is described suppress plate and suppress be installed with spring between lid on bucket.
When suppressing plate and continuing upward rising, the valve rod in two-way valve by lever pushing continue downwards, when valve rod it is pushed
During to lower dead center, suppress plate and throw away and continue upward rising, in order to protect two-way valve without damage, the two-way valve bottom and the peace
Spring is installed between dress housing
In order to the rise and fall for ensureing lever two ends pin joint it is highly consistent, and suppress plate with two-way valve valve rod it is upper
What is risen and decline is highly consistent, and the middle position of the lever is connected with the installation housing into rotation.
The beneficial effects of the utility model are:Pneumatic scroll saw with automatic shutoff protection device of the present utility model, knot
Structure is simple, reasonable in design, and only when suppressing the hydraulic pressure in bucket and reaching more than 0.15MPa, nozzle is sprayed water on saw blade, ability
Gas in air compressor is imported into air motor, so as to realize cutting, spark is enough timely put out by the water energy that nozzle sprays
Go out, it is to avoid the gas explosion that electric spark causes, security performance are higher, substantially increase air motor performance parameter and its
Service life, work task efficiency are greatly improved, and security is ensured.
