Problems solved by technology

[0004] When the hydraulic steering gear in the prior art is used for a long time, when the pressure gauge is damaged, the pressure gauge needs to be replaced. At this time, the pressure gauge switch needs to be turned off to block the oil circuit before the pressure gauge can be disassembled. It is inconvenient to disassemble and assemble, and needs to be improved

Abstract

The invention discloses a direction-adjustable self-closing pressure gauge valve, relates to a pressure gauge, and aims at solving the technical problem that in the prior art, a pressure gauge is inconvenient to disassemble is solved. The key points of the technical scheme are that the device comprises a cylinder connected with an oil tank; an ejector pin is arranged at the end, close to the oil tank, of the cylinder; a through groove communicated with the oil tank is formed in the ejector pin, a flow channel communicated with the through groove is formed in the cylinder, the ejector pin is sleeved with a self-closing assembly used for closing the flow channel, and a pressure gauge used for driving the self-closing assembly to open the flow channel is connected to the side, away from the ejector pin, of the cylinder. When the pressure gauge needs to be disassembled, the pressure gauge is disassembled, the self-closing assembly is used for closing the flow channel and blocking flowing of hydraulic oil, a new pressure gauge is installed on the cylinder, the pressure gauge drives the self-closing assembly to open the flow channel, the hydraulic oil flows again, and use is reduced so that the pressure gauge can be disassembled and assembled conveniently and rapidly.

Description

technical field [0001] The present invention relates to a pressure gauge, more specifically, it relates to an adjustable self-closing pressure gauge valve. Background technique [0002] A pressure gauge refers to an instrument that uses elastic components as sensitive components to measure and indicate pressure higher than the environment. The conversion mechanism transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure. This table can be seen everywhere in the fields of heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle repair and maintenance shop and so on. [0003] The Chinese patent with the authorized announcement number CN201849659U discloses a marine hydraulic steering gear, including a power pump set composed of hydraulic pumps, a fuel tank, a low liquid level alarm installed on the fuel tank, an air filter and an oil return filter. device, pressure gauge, steering mechanism, trav...
