Problems solved by technology

When the fire extinguisher is produced, the fire extinguishing agent is first filled in the bottle, and then the valve is screwed on, but sometimes the pressure in the bottle is abnormal, and the pressure is often too high or too low, resulting in poor quality of the fire extinguisher
At present, for this situation, it is often necessary to remove the valve and refill it, which is very troublesome, and the existing technology does not have the maintenance function

Abstract

The invention discloses a valve with maintenance function, which relates to the technical field of fire extinguisher components; it includes a valve body, an air inlet pipe, an air outlet, a piston, a carrying handle, and a push-down handle. Connected with the air intake pipe, the inspection port is equipped with a second piston adapted to it, the inspection port is equipped with a spring, the side of the second piston facing the outside of the inspection port is fixedly connected with a push rod, and the top of the valve body is provided with a guide groove , the bottom end of the guide groove is provided with a groove, the guide groove is provided with a pressure rod, the bottom end of the pressure rod is bent toward the piston to form a connecting rod, the lower side of the connecting rod is provided with a second spring, and the bottom end of the second spring is connected to the concave On the lower side of the groove, the top of the second spring is connected to the connecting rod, the upper edge of the piston is provided with a truncated cone, and the top of the intake pipe is provided with a top tight slope matching the truncated cone. Under the action of the second spring, the top of the truncated cone Tight on the tight slope, the top of the pressure rod is connected with rollers in rotation. The invention is convenient to adjust the pressure and has the function of maintenance.

Description

technical field [0001] The invention belongs to the technical field of fire extinguisher parts, in particular to a valve with a maintenance function. Background technique [0002] Valves are very important components in fire extinguishers. When the fire extinguisher is produced, the bottle body is filled with fire extinguishing agent first, and then the valve is screwed on, but sometimes the pressure in the bottle body is abnormal, and the pressure is often too high or too low, resulting in poor quality of the fire extinguisher product. At present, in view of this situation, the valve often needs to be removed and then refilled, which is very troublesome, and the existing technology has no maintenance function. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a valve with an overhaul function in order to overcome the disadvantage that the prior art does not have an overhaul function. [0004] In order to achieve the above object, the p...
