Background technique
In ship domain, such stopcock accessory (cock fitting) device is that people are known.Usually, a plurality of such independent stopcock fitting systems are arranged in boats and ships, they are connected on the one hand to one of the motor power supply public power supply system, are connected to a centre data processing system that is used for electronic operation and control stopcock fitting system on the other hand.
There is a main shortcoming in such device well known in the prior art.In oil conservator, do not have anything else usually, have only oil.If slight leakage (this is always possible, the environment of particularly supposing the work of stopcock fitting system is extremely severe, especially under the situation of boats and ships) takes place, may have little air to enter into oil conservator.In this case, as the function of the vertical relatively gravity alignment of oil conservator, especially in the boats and ships that wave and face upward volt, at a time this system may be aligned to, and pump is not to be pumped into oil from oil conservator, but is pumped into air.The result is that the valve of stopcock can't carry out work again.In order to address this problem, require oil conservator to be installed on the very accurate position at present, generally be vertical as much as possible, in the limited boats and ships in space, be to be unfavorable for such installation.Certainly, a kind of method of solution is to provide a kind of oil conservator of special leakproof.But this solution cost is very high.
A kind of hydraulic system with an elastic wall oil conservator has respectively been described by the U.S. 4064911 and Germany 1962711.The purpose of being quoted from these documents of prior art is to prevent air penetration in oil conservator, so that do not worsen the hydraulic fluid that contacts with air and reduce total noise.Oil conservator described in the literary composition is only installed along vertical position, suction pump below.
In these documents, do not mention and on boats and ships, to use such hydraulic system, do not mention that oil conservator may face upward volt and be rocked on the position outside the described position and the problem that causes yet.
Summary of the invention
Even the present invention is intended to overcome by the stopcock fitting system that proposes under a kind of any state on boats and ships, particularly can work these problems of prior art when boats and ships wave or face upward volt consumingly and oil conservator can be placed on any position substantially simultaneously.
According to the present invention, a kind of navigation instrument, comprise at least one stopcock, one is used to the hydraulic actuator and that activates stopcock to be used for the operation equipment of hydraulic actuator, this operation equipment comprises an oil hydraulic pump, a gear pump and one has the oil conservator of a housing in particular, pump is connected to the oil conservator that is used for this liquid by a suction pipe, oil conservator is installed on the fixed pan of relative navigation instrument, in the process of navigation instrument proper functioning, this fixed pan perpendicular to this navigation instrument, vibrate around a equilibrium position corresponding to the direction of earth gravity effect, it is characterized in that at least a portion of the housing of oil conservator is made with elastic material.Dependent claims has defined improved form of the present invention.
Therefore, if oil from oil hydraulic circuit spill or the volume of oil because the work of the hydraulic system of temperature variation or operation when changing, the flexible part of housing can contraction or expansion, regulating the capacity of oil conservator, thereby adapts to oily new volume.Therefore, not having any air at the liquid level place of suction pump exists.The result is can install according to any alignment direction whatsoever according to system of the present invention, and still work with flying colors, particularly in the boats and ships that wave or rise and fall.This is particularly favourable in navigation instrument, boats and ships or aircraft, in these occasions, people always do not have the needed whole spaces of a system that have with the oil conservator of ten minutes accurate way alignment are installed, and such occasion is to vibrate around the direction of gravity at work.According to the present invention, in fact oil conservator can be installed in boats and ships or carry-on any position, and this can not have influence on its work.
Be preferably, elastic material also is flexible.
Be preferably, elastic material is a rubber, for example nitrile.
Be preferably, the integral body of oil conservator housing is made with an elastic material.
Be preferably, oil conservator is arranged to its housing and is out of shape at least in one direction, for example on oil conservator vertical.In order to realize such distortion, one or more reinforcement guiding elements can be set, these guiding element support housings, and still allow the fluctuation of its pattern of passing through bellows on this described at least one direction, to be out of shape simultaneously.By this measure, can obtain the method that a kind of foolproof judgement has oil leakage to go out.In fact, the displacement transducer that the displacement on the direction of the housing of monitoring the oil conservator of being concerned about on the edge is set is enough, and a sensor directly passes information to centring system then.
The invention still further relates to a stopcock fitting system, it comprises a stopcock by the hydraulic actuator actuating, and described hydraulic actuator is operated by an operation equipment according to the present invention.
The invention still further relates to a navigation instrument, especially boats and ships or an aircraft, it comprises a center feed system, a centre data processing system and at least one according to stopcock fitting system of the present invention, and each said system all is connected to centring system.
The accompanying drawing summary
Now with reference to accompanying drawing, only be to describe one embodiment of the present of invention in the mode of example.In all accompanying drawings:
Fig. 1 represents the part of boats and ships, says so more specifically to comprise that the stopcock fitting system of a plurality of independent stopcocks, these stopcocks are connected to a supply network on the one hand, are connected to a data transport network that is used for center operations and control unit on the other hand;
Fig. 2 is the stereogram of a part that is used for the operation equipment of an actuator;
Fig. 3 is the stereogram of a complete stopcock fitting system; And
Fig. 4 is a bellows embodiment's of oil groove a view.
Embodiment
In Fig. 1, schematically expressed the public line feed device 1 that is used for a plurality of independent stopcock fitting systems 2 in boats and ships.In addition, also be provided with a centre data processing system 3, be called center cell, it is connected to each stopcock fitting system 2 by a data/address bus, in these stopcock fitting systems each is carried out the concentrated area operation.This operation normally realizes by the signal that transmits numeral or simulation.
In Fig. 3, expressed an independent stopcock fitting system 2 in more detail.Stopcock fitting system 2 is made of the operation equipment 7 that a stopcock 4, a hydraulic actuator 6 and are used for hydraulic actuator, and stopcock described here is a right angle stopcock, but it also can be the valve of a linear valve or any other type equivalently.The operation equipment 7 that is used for hydraulic actuator is made of a motor 8, an oil hydraulic pump 9 and an oil conservator 10, and oil hydraulic pump described here is a gear pump, but it also can be the pump of any other type equivalently.This operation equipment 7 is connected to hydraulic actuator 6 by an oil hydraulic circuit.Such device is being that people are known in the art.
Pump 9 is connected to oil conservator 10 by a suction pipe, and pump is according to the desired operation of stopcock and by this suction pipe suction oil or discharge some oil.
Oil conservator 10 is made of a housing 11.The flexible elastomeric material of these housing 11 usefulness is made, and particularly makes with nitrile.
In should using, use " flexible " to be meant a kind of like this matrix or material, when it on a given direction, elongate at least corresponding to relative one initial state of rest be 15% or more elongation rate one apart from the time, the original state before can being returned to it and stretching.Preferably, this lower limit equals 50%, more is preferably 100%.
Figure 4 illustrates the figure of the oil conservator 10 that is arranged to a bellows form, the oil conservator 10 of this bellows form is remained on the given direction z by a guiding element of strengthening pipe 12.But oil conservator 10 can slide on the z direction along pipe 12.In addition, be provided with a sensor 40, it surveys the motion of the displacement of the protuberance 50 on the top that is connected housing 11 with detection housing 11, and sends signals to a local electronic operation system 20 that is used for this stopcock.Then, even (people know for this leakage or the excessive consequence that does not have a short-term according to the present invention, as long as the leakage of oil is less, may not exist air penetration to go into oil conservator according to the present invention), the local electronic operation system 20 that is used for this stopcock also can send a signal or activate an electroluminescent diode or other warning device to centring system, with warning in oil groove, take place to leak or oil mass too much.
Occur when leaking, for example by means of the minute crack in hydraulic seal, oil may be overflowed from the loop.But in this case, the oil conservator elastic shell will shrink with consistent with the accurate shape of the oil of residual volume.Therefore in this oil conservator inside, only there is oil, so that pump 9 can only be pumped into oil rather than air.If situation about expanding, then phenomenon is opposite.
In addition, in situation embodiment illustrated in fig. 4, the top of the oil conservator of bellows form can sink along the z direction, and sensor can detect the displacement at this top by the motion that detection is connected this top upper convex portion, so just can report to the police.Center cell can require to interfere then.But before interfering, hydraulic actuator is proceeded, and carries out work with fault-free ground.
