Abstract
The utility model discloses a safety valve convenient to adjust. The safety valve convenient to adjust comprises a valve body, a valve rod, a spring, a valve element and a sealing ring. The valve body comprises an upper valve body and a lower valve body which are in threaded connection. Multiple vent holes are formed in the lower valve body. The upper end of the spring is fixedly connected with the inner top of the upper valve body through an upper fixing block and the lower end of the spring is fixedly connected with the valve element through a lower fixing block. A protruding top ring is arranged at the upper end of the lower valve body. An ejection screw is in threaded connection with the position, corresponding to the top ring, of the upper valve body. A brush base is arranged on the portion, on the periphery of the valve rod, at the upper end of the upper valve body. A brush is arranged inside the brush base. Compared with the prior art, the safety valve convenient to adjust is simpler in structure and easier to operate; the structure that the upper valve body and the lower valve body are in threaded connection is adopted in the valve body, so that the safety valve is more convenient to repair; the brush is arranged at the upper end of a gap between the valve rod and the valve body, so that dust is effectively prevented from entering the gap and the safety valve is safer.
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.
The complex structure of existing safety valve of air compressor, inconvenient maintenance, the pressure of safety valve regulates inconvenience, and the larger gap of existence between the valve rod of existing safety valve and valve body, can cause dust to enter between valve body and the gap of valve rod being placed in for a long time air, thereby cause valve body and valve rod stuck phenomenon, make safety valve cisco unity malfunction, have larger potential safety hazard.
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 convenient safety valve regulating.
The technological scheme that the utility model is taked for its technical problem of solution is:
A kind of convenient safety valve regulating, comprise valve body, described valve body comprises upper valve body and lower valve body, and upper valve body and lower valve body screw thread are affixed, lower valve body is provided with multiple exhaust ports, slidably connect valve rod in upper valve body upper end, exterior circumferential at the valve rod that is positioned at upper valve body is provided with spring, spool is fixed in the bottom of valve rod, seal ring is arranged on the bottom of spool, upper fixed block is passed through by affixed to spring and upper valve body inner top in described spring upper end, the lower end of spring is fixedly connected with spring by lower fixed block with spool, be provided with the collar of a circle projection in described lower valve body upper end, on described upper valve body, on the position corresponding with collar, be threaded and one held out against screw, around being positioned at valve rod, upper valve body upper end is provided with a woollen brush base, be provided with hairbrush in woollen brush base inside.
The beneficial effects of the utility model: the utility model compared with prior art structure is simpler, pressure that can regulation safety valve by twisting upper valve body, operate easier, and the structure that valve body adopts upper and lower valve body screw thread to connect makes safety valve maintenance convenient, in the upper end, gap of valve rod and valve body, hairbrush is installed and has effectively been prevented that dust from entering in gap, makes safety valve safer.
