Description
Self-chosing indicator for fluid level of the present invention is the level instruction device on the fuel tank in engineering machinery or the power pipeline.
In existing fluid level gauge, no matter be the water level indicator on the boiler, the oil level indicator of installing on fuel tank on the still domestic and international various large, medium and small type ship oceangoing ships, the Oil Tank, indicating device commonly used does not all have self-chosing indicator for fluid level from its principle of compositionality.
The objective of the invention is to provide a kind of self-chosing indicator for fluid level, particularly all can close a kind of self-closing level instruction device that fuel tank leads to the oil circuit of oil level display unit when breaking out of fire or oil level display unit damage automatically.
The objective of the invention is to finish as follows: self-chosing indicator for fluid level is made up of main parts in addition such as upper and lower two quick closing valves, oil level display unit, manual cocks.Have oil circuit between quick closing valve, oil level display unit and the manual cock, interconnect.On structure arrangement, the side of quick closing valve fuses with manual cock, and the cock that blowdown is used is equipped with in the lower end of following quick closing valve body, and upper and lower quick closing valve body constitutes mechanical connection by oil level display unit.Upper and lower quick closing valve inner structure is basic identical.Energy storage unit, piston are housed in the quick closing valve body, oil circuit are arranged on the piston, be equipped with between quick closing valve body and the oil level display unit glass tube in 100 ℃ of-500 ℃ of temperature ranges can softening transform the equalizing bed made of material.Self-chosing indicator for fluid level is when operate as normal, and quick closing valve relies on the anchorage force of the glass tube in the oil level display unit to pass to energy storage unit by equalizing bed and piston.According to the action principle of energy storage unit, can be out of shape storing energy after the energy storage unit employing is stressed, can recover the material of the preceding state of distortion after the power cancellation and make.Therefore the energy storage unit after stressed is subjected to displacement or is out of shape the piston that is connected with it is produced with respect to the axial displacement between the valve body, causes the oil circuit between quick closing valve body and the oil level display unit unimpeded.Reach the purpose of the oil level in correct indication fuel tank or the Oil Tank.When breaking out of fire, by the temperature of flame,, give the equalizing bed that contacts with the oil level display unit glass tube in the valve body with temperature conduction by the valve body of quick closing valve, make equalizing bed generation softening transform or fusing, cause glass tube that the anchorage force of piston is reduced.Like this energy of energy storage unit savings since anchorage force will give off energy will recover position before its displacement or the distortion after reducing the time and promote piston and do with respect to the axial displacement between the valve body, work the purpose of closing the oil circuit between quick closing valve body and the oil level display unit, play self-closing effect; Or work as oil level display unit owing to reasons such as baked wheaten cake or mechanical damages, after oil level display unit is damaged, lost the anchorage force that passes to energy storage unit by piston, at this moment energy storage unit will utilize the recovery displacement of itself or during the state before the distortion function and giving off energy promote piston and do displacement with respect to valve body, make piston close oil circuit between quick closing valve body and the oil level display unit, play self-closing effect.
The present invention has been owing to adopted by the self-chosing indicator for fluid level formed of parts in addition such as quick closing valve and equalizing bed, thereby solved the shortcoming of the fluid level gauge of using always in the present boats and ships effectively, and because of existing fluid level gauge, commonly used have following three kinds of patterns:
One, the fluid level gauge of no self-closing effect mainly is made up of manual cock and glass tube.Owing to burn or can not close oil circuit during mechanical damage, or cause fire when glass tube; Or cause leakage of oil, and particularly when fire that leakage of oil causes, cause pouring oil on the fire, cause hardly imaginable consequence.
Two, the self-chosing indicator for fluid level of using on the boiler mainly utilizes the work of pressure differential principle.But when pressure differential will lose self-closing effect during less than certain value.The self-chosing indicator for fluid level of this pattern can only be used for general boiler, can not be used for fuel tank or Oil Tank on the boats and ships.
Three, normally closed type fluid level gauge only can correctly be indicated liquid level under the situation of manually driving valve, can not correctly indicate liquid level at ordinary times, uses inconvenience.
Self-chosing indicator for fluid level of the present invention can be implemented with reference to diagramatic way:
The manual cock of self-chosing indicator for fluid level by being made up of jam nut (1), cock (2), an end is connected with fuel tank.Can close the oil circuit that fuel tank leads to quick closing valve by manual cock in case of necessity.Manually the other end of cock is connected with quick closing valve.Quick closing valve has last quick closing valve, following quick closing valve.Inner structure is basic identical.Spring (10) is housed as energy storage unit in the quick closing valve body (11), piston (12) is equipped with in the spring upper end, and oil circuit is arranged on the piston.The lower end of following quick closing valve body links to each other with the sewage component that cock (2), handle (4), joint (3), gland (5), faucet body (6), external thread gland (9), O-ring seal (8), nut (7) are formed.Be equipped with between the quick closing valve up and down by friction top (15), glass tube (16), protection steel wire (17), nut (18) and form the oil level indicating device.Last quick closing valve upper end is by the pressure of spring compressor (19) levelling spring to piston.Glass tube (16) is supporting piston (12).The equalizing bed (13) that makes with easily softening material is housed between the end face of glass tube and piston.For the purpose of sealing, between compacting ring (14) and valve body (11), oil seal ring (20) is housed.
When normal operating conditions, quick closing valve relies on the anchorage force of glass tube (16) to pass to the energy storage unit spring (10) that is connected with it by piston (12), makes to compress behind the spring stress and make a concession.The result who makes a concession makes the piston that is connected with it produce axial displacement with respect to valve body, causes the oil circuit between quick closing valve chamber and the oil level display unit glass tube unimpeded.Under the nominal situation, upper and lower manual cock all is in open-circuit condition, and fuel tank all is communicated with oil circuit between the oil level display unit like this, can correctly indicate the oil level in fuel tank or the Oil Tank.When breaking out of fire,,, give equalizing bed (13) with temperature conduction by the valve body of quick closing valve by the temperature of flame.Owing to being out of shape after easily the equalizing bed of softening transform is heated or burning, reduced the end play between glass tube (16) and the valve body (11), also just reduced glass tube (16) passes to spring (10) by piston (12) pressure, spring extends under the effect of self storing power, promoting piston (12) does with respect to the axial displacement between the valve body, reach the purpose of closing the oil circuit between quick closing valve body and the oil level display unit, play self-closing effect.When reasons such as breaking out of fire or mechanical damages, make glass tube (16) fracture fragmentation after, just lost anchorage force to piston (12), spring loses pressure and extends, and promotes piston and closes oil circuit between quick closing valve chamber and the oil level display unit, plays self-closing effect.
