Abstract
The utility model relates to a liquid level automatic regulator, which is characterized in that the utility model is composed of a regulator and a phase change pipe, wherein, an input port of the regulator is communicated with a controlled container through a pipeline; a steam chamber of the regulator is connected with the phase change pipe, and the other end of the phase change pipe is directly connected with the controlled container. The regulator is composed of the steam chamber and a stainless steel valve core, wherein, the valve core is a gradually enlarged structure, and a development opening is fixed on an output port in the regulator. The liquid level automatic regulator has the advantages of accurate signal collecting, high control sensitivity, simpler structure, high reliability and low cost.
Description
The utility model belongs to a kind of liquid level self-checking device, does not particularly have the liquid level automatic regulator of mechanical moving component and electrical equipment, steam-operating parts about a kind of main loop.
In the patent No. be: 95204913.9; 97239699.3; 97242239.0 in 94246917.8 4 utility model patents, a kind of self-regulation liquid level meter is disclosed, it mainly is made up of signal tube and variable valve, signal tube is used for getting water level in the industrial container, the water communicating pipe of outer signal tube and vapour communicating pipe and industrial container join, the control signal of variable valve is taken from signal tube, the liquid level that the liquid level reflection of signal tube needs to dredge flow device, the variable valve of this device adopts the Laval structure substantially, do not have mechanical moving component and do not need electric vapour control element yet, should not damage the reliability height.But because the water communicating pipe of outer signal tube and vapour communicating pipe and industrial container join, the pipe damping of its two pipeline falls, and is subjected to on-the-spot restriction, can't quantitatively be guaranteed, so the signal tube liquid level not exclusively equals the liquid level in the industrial container.The vapour locking of signal tube loss in addition, the vapour signal that the liquid level self-regulating valve is gathered is inaccurate, and this self-regulation liquid level meter control performance is descended.
The purpose of this utility model is: a kind of liquid level self-checking device is provided, and its signals collecting is accurate, controls highly sensitively, and structure is simpler, the reliability height, and production cost is low.
The technical solution of the utility model is: design a kind of liquid level self-checking device, it is characterized in that: it is made of regulator and phase transition tube; The regulator input port is connected with the Be Controlled container by pipeline; The steam chest of regulator is connected with phase transition tube, and the other end of phase transition tube directly is connected with the Be Controlled container.
Described regulator is made of steam chest and stainless steel spool; Spool is the flaring structure, and deployment opening is fixed on the interior output port of regulator.Have elbow to be fixed in the Be Controlled container on described and the phase transition tube other end that the regulator steam chest is connected, the elbow mouth is a level.
Characteristics of the present utility model are:
1, because this liquid level self-checking device mainly is made of regulator and phase transition tube, removed signal tube than original liquid level automatic regulator, signals collecting is directly taken from the Be Controlled container, the water level signal true and accurate, and adjusting function is good, controls highly sensitive.
2, a kind of regulator disposes a tapered configuration at endpiece water conservancy diversion current limiting element is disclosed in the patented claim of the patent No. 97239699.3.When hydrophobic self tuning regulator inlet enters, dispose from endpiece in the water conservancy diversion current limiting element hole of a tapered configuration and flow out, because latus rectum is big from little unexpected change, thereby the flow velocity anticlimax produces cavitation, cavitation is created in the rear portion pipeline again, and pipeline generally adopts common iron, so easily by cavitation.And regulator of the present utility model is made of steam chest and stainless steel spool; spool is the flaring structure; deployment opening is fixed on the interior output port of regulator, so it is the same with the rear portion of drawing valve that structure spool, when hydrophobic self tuning regulator inlet enters the spool import; because the aperture becomes big gradually from little; along with the flaring flow velocity of structure reduces gradually, can effectively reduce cavitation phenomenons, thus the safety of protection regulator rear portion pipeline section; increase the service life, and the anti-cavitation of the spool of stainless steel material.Have an influence that the regulator regulator spool more of the present utility model that draws your structure of valve does not have admission opening design fetch bit and Size Error with former, simple in structure, manufacturing process is also simple, and production cost is low, and reliability is higher.
3, owing to have elbow to be fixed in the Be Controlled container on the phase transition tube other end, the elbow mouth is a level, so collection is more accurate.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Accompanying drawing 1 is an embodiment user mode syndeton synoptic diagram.
Accompanying drawing 2 is embodiment regulator partial structurtes cut-away views.
Among the figure: 1, Be Controlled container; 2, pipeline; 3, regulator; 4, flaring spool; 5, variable valve; 6, by-pass valve; 7, phase transition tube; 8, elbow; 9, steam chest.
As shown in the figure, regulator 3 is made of steam chest 9 and stainless steel flaring spool 4, and the maximum deployment opening of flaring spool 4 is fixed on the interior output port of regulator; Phase transition tube 7 one ends are connected with steam chest 9, have elbow 8 to be fixed in the Be Controlled container 1 on the other end, and the elbow mouth is paralleling with liquid level of level.The input port of regulator 3 is connected with Be Controlled container 1 by pipeline 2; Be installed in parallel a by-pass valve 6 with anti-leak at regulator 3 two ends; But in variable valve 5 manual shift of regulator 3 input port end polyphones.The stainless steel spool of regulator also can be to draw valve that structure.
During use, under certain pressure, the vapour-liquid ratio tolerance is very not big, and when liquid level was in equilibrium state in the Be Controlled container 1, regulator 3 vapour-liquids of flowing through flowed out by certain resistance ratio.When liquid level in the Be Controlled container 1 was elevated to phase transition tube 7 interfaces, at this moment phase transition tube 7 became discharging tube, and the fluid flow of the regulator 3 of flowing through increases.Liquid level descends rapidly and recovers normal liquid level in the Be Controlled container 1.On the contrary, when liquid level in the Be Controlled container 1 descended, phase transition tube 7 ports were freely opened entirely, and the throttle flow of regulator 3 increases, and promptly vapour locking increases, and the flow quantity of the regulator 3 of flowing through reduces.Liquid level rises recovery normally in the Be Controlled container 1.Liquid level is in metastable state all the time so repeatedly.Reach automatic adjusting purpose, the self-regulated process of this liquid level, very sensitive reliable.
