Abstract
The utility model discloses a novel bent tube type safety valve which comprises an L-shaped valve body, wherein a mounting tube for communicating a valve channel with the outside is arranged at the bent part of the valve body; a valve clack is mounted at the joint of the mounting tube and the valve body; the valve clack is movably connected with the valve body through a moving pin; a torsional spring is mounted on the moving pin; one end of the torsional spring is in lap joint with the valve clack, and the other end of the torsional spring is in lap joint with the valve body; a sealing ring is arranged at the lower end of the valve clack; the valve body is internally provided with a step structure matched with the valve clack. The safety valve has the benefits that compared with the prior art, the safety valve is simpler in structure, the valve clack is sealed by the torsion of the torsional spring inside the valve body, and the torsion of the torsional spring cannot be affected by external force, so that normal operation of the safety valve is ensured, and moreover the safety valve has the advantages of rapid exhausting and the like as the exhaust hole of the safety valve adopts pipeline-type exhausting.
Description
Technical field
The utility model belongs to air compressor accessory technical field, the particularly safety valve on air compressor.
Background technique
Air compressor is a kind of general machinery, in more equipment as supporting application.
Existing safety valve of air compressor is that push rod and spring are installed between valve body suction port and air outlet, spring heads on seal ring and makes suction port sealing, the pressure size of safety valve is determined by spring force, and spring force is regulated by adjusting screw, the shortcoming that its prior art safety valve of air compressor exists is that the tail end of push rod exposes, in the time that unexpected masterpiece is used in push rod tail end, the pressure of spring changes, Unloading Effect while not having design, namely do not reach safe object, therefore can cause air compressor pressure to exceed the accident that designs pressure.
Model utility content
In order to overcome the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of novel bent-tube boiler safety valve.
The technological scheme that the utility model is taked for its technical problem of solution is:
A kind of Novel bent tubular type safety valve, comprise a L shaped valve body, be provided with a mounting pipe that valve channel is in communication with the outside at valve body bending part, jointing place at mounting pipe and valve body is provided with flap, and described flap is flexibly connected by loose pin with described valve body, and torsion spring is installed on loose pin, one end of torsion spring is overlapped on flap, the other end is overlapped on valve body, and described flap lower end is provided with seal ring, is provided with the ledge structure matching with flap in valve body.
In described mounting pipe, be provided with a regulating block, described regulating block is provided with the staircase structural model of different heights, the torsion spring end being overlapped on valve body is overlapped on described regulating block, in described mounting pipe, be provided with the groove of a regulating and controlling piece, bottom at described regulating block is provided with sealing gasket, screw interted groove and regulating block affixed.
In described mounting pipe, be sealed and installed with pipe lid.
The beneficial effects of the utility model: the utility model compared with prior art structure is simpler, the torsion of the torsion spring of flap by being arranged on valve inner seals, the torsion of torsion spring can not be subject to External Force Acting, guarantee the normal use of safety valve, and the utility model safety valve relief opening is pipeline air exhaust water, there is the advantages such as exhaust is fast.
