Abstract
A fuel gas valve with temp protection features that it can be automatically closed under the condition of abnormal high temp and then manually opened. It is composed of valve body, valve cover, piston module, boosting spring, and shape memory alloy.
Description
Technical field
The present invention relates to a kind of gas valve, especially can have need not under the high temperature abnormal conditions power supply can turn-off voluntarily gas supply the gas valve that has temperature protection it belong to the gas valve production industry.
Background technique
Combustion gas comprises natural gas, coal gas and liquefied petroleum gas (LPG) etc. are to develop novel energy rapidly over past ten years, a large amount of uses of combustion gas are the performances of social progress and urban modernization, it has reduced the municipal pollution degree widely, also bring great convenience and efficient simultaneously to people, but also many disasters have been caused simultaneously thus to society, a harm that causes because of gas leakage and day poly-increasing, the loss that the disaster that causes because of combustion gas causes to people's lives and properties is an immeasurable problem, it is compared with the general coal-fired fire that takes place, has emergentness more, and difficult feel is looked into and is had more danger, still provides fearful thing especially continuously by its combustion gas when fire takes place.
A lot of at this type of problem in recent years, be used for Fire alarm installation and push market and also played certain effect really, but most of product in the market is passive warning type, can only report to the police and can not further get rid of to fall into and suffer from.Even especially nobody the time alarm work, really because of unmanned eliminating hidden danger, and can not deal with problems.Also there are some imported products when reporting to the police, to close combustion gas in recent years.But be difficult to the general utmost point eventually because of price is higher.And all these class warning products all must can be worked by electric power.Therefore very inconvenient, more frequent generation is supplied with to equip to work because of non-transformer and is caused fire.What is more because of device proper short circuit self burning causing fire.
Summary of the invention
The purpose of this invention is to provide a kind of easy for installationly and can be when abnormal high temperature takes place, close voluntarily and cut off fuel gas supply and avoid bigger fire disaster not by any electric power.Prevent to endanger the gas valve that has temperature protection of stretching.
To achieve the object of the present invention, the inventor utilizes marmem as heat responsive element, STRESS VARIATION that utilization produces when different temperatures promotes outer magnetic ring and moves, and outer magnetic ring mobile caused identical the moving of the inner magnetic core in the valve and stop up combustion gas by cutting off the supply of combustion gas.Its structure is the piston sleeve of a sealing of having spun on valve body; being placed with a piston that has magnetic core in the inside of piston sleeve leans on; with the big piston assembly that is used for opening and closing; having power assistant spring and outer magnetic ring assembly and marmem to be connected with an overcoat on piston sleeve in the outer installment of piston sleeve is used to protect outside outer magnetic ring and the power assistant spring; a Luo bar that is used to regulate temperature is arranged at the top of shell, at the locking closure that is externally connected to of shell.The state that keeps the opening and closing of valve when being used for valve working.
Description of drawings
Accompanying drawing has the oblique side portion structure schematic representation of gas valve of temperature protection for the present invention.
In the accompanying drawings, 1. valve body, 2. valve gap, 3. piston assembly, 4. the magnetic post, 5. power assistant spring, 6. the outer magnetic ring assembly, 7. marmem, 8. regulate gland, 9. shell, 10. outer housing cover, 11. is regulated Luo bars, 12. long locks.
Embodiment
For being carried out more detailed explanation, the present invention carries out embodiment's illustrated embodiments: at first with magnetic post 4 below in conjunction with Figure of description; Put into the inside of valve gap 2, the valve gap 2 that the cavity that piston assembly 3 is put into valve body 1 will have a magnetic post 4 and empty body 1 cylindrical that a following circle of reinstating valve gap 2 pushes down piston assembly 3 that spins closely cooperates itself and valve body 1.Shell 9 is inserted in the outside that the outer Luo line of valve gap 2 back and valve gap 2 spins and firmly power assistant spring 5 is inserted in valve gap 2, again outer magnetic ring assembly 6 marmems is regulated gland 8 down, be inserted in and outer housing cover 10 be pressed into shell 9 behind the outside of valve gap 2 it is fixed successively.To regulate Luo bar 11 and screw in outer housing cover.The side that 10 Luo line makes adjusting Luo bar compressing adjusting gland 8 will grow lock 12 and shell 9 outward spins.Cooperate with outer magnetic ring assembly 6.So far whole valve assembling finishes.
Combustion gas enters system by valve and is not affected during use, and the suction pressure of this moment produces thrust piston assembly 3 upwards to the piston assembly in the valve body 3 and upwards lifts and opens air outlet hole, so gas safe passes through.Temperature rises when reaching the operating temperature of marmem in case environment changes, marmem 7, expansion, when expanding because of marmem 7, there is the gland of adjusting 8 to stop at an upper portion thereof and causes marmem 7, can only move downward, and outer magnetic ring assembly 6 is forced to move down, when outer magnetic ring assembly 6 moved down the relevant position, kayser 12 was locked.After preventing that temperature is normal, outer magnetic ring assembly 6 is boosted by power assistant spring 5, center hole with piston assembly 3 when outer magnetic ring assembly 6 moves down stops up: cause the pressure in the valve body constantly to increase, air outlet hole in the valve body is closed, valve does not have combustion gas to be passed through, when needing to ventilate work after the artificial affirmation, under the effect of the magnetic line of force, upwards lift the center relief hole of having opened piston assembly 3 together and cause top strength in the valve body less than suction pressure as long as pulling kayser 12 power assistant spring 5 upwards boost the outer magnetic ring assembly magnetic posts 4 in the valve gap 2 automatically.Suction pressure lifts combustion gas with piston assembly 3 and passes through valve.
Facts have proved that the method is reasonable in design reliable, and price is low.
