Liquefied gas cylinder valve timing automatic switch manipulator

Abstract

The invention discloses a timing automatic switch manipulator for a main valve of a liquefied gas steel cylinder. The timing automatic switch manipulator comprises a fixed frame fixed on the steel cylinder; the fixed frame is provided with a manipulator device connected with the main valve; the manipulator device comprises an operating platform; the operating platform is provided with a timing switch; the timing switch is connected with a control module with a power supply; the control module is connected with a motor; the bottom of the operating platform is provided with a valve opening in-place limiting switch and a valve closing in-place limiting switch; a mounting plate is arranged below the operating platform; a rotating plate is arranged between the operating platform and the mounting plate; the rotating plate is provided with a valve opening in-place block, a valve closing in-place valve and a limiting block; the center of the rotating plate is provided with a rotating strip connected with the motor; both ends of the rotating strip are connected with the rotating plate by springs; the lower part of the rotating plate is provided with a spindle connected with the main valve; the spindle is fixed on the mounting plate by a bearing. The timing automatic switch manipulator for the main valve of the liquefied gas steel cylinder can close the main valve in a timing manner, is safe and reliable to use and is simple and convenient.

Description

Technical field [0001] The invention relates to a valve manipulator device, in particular to a timing automatic switching manipulator for a liquefied gas cylinder main valve. Background technique [0002] Nowadays, household use of liquefied gas is very common. The existing switches for liquefied gas cylinders are all manually operated, but a slight negligence sometimes forgets to close the valve, which poses a great threat to people's life and property safety. [0003] Therefore, people have installed a solenoid valve switch on the pipeline between the main valve and the gas stove to realize the function of timing on and off the gas. Although the temporary switch is solved, the main valve of the liquefied gas cylinder is still open, so there is still some Security risks. Summary of the invention [0004] The purpose of the present invention is to provide a manipulator for timing and automatic switching of the main valve of a liquefied gas cylinder. The invention can close the mai...

Problems solved by technology

[0002] It is very common to use liquefied petroleum gas at home now. The switches of the existing liquefied petroleum gas cylinders are all manually operated, but if there is a slight negligence, sometimes the valve will be forgotten to close, which poses a great threat to people's life safety and property safety.

[0003] Therefore, people have installed a solenoid valve switch on the pipeline between the main valve and the gas stove to realize the effect of timing on-off gas. Although the temporary switch has been solved, the main valve of the liquefied gas cylinder is still open, so there is still a certain of security risks
