Abstract
The utility model provides a fully hydraulic automatic control the quantity for packaging device. The utility model uses a normally closed button valve, only if the button is pressed, the plunger valve and the packaging gun lie in a conducting position and begin fluid packaging. When the packaging amount is reached, the hydraulic oil on the top of the plunger piston is pressed out through a one-way valve, the plunger piston moves upwards, the packaging gun is turned off, and the fluid packaging is automatically stopped. The utility model has the advantages of more accuracy limited packaging, simple structure, easy operation, cost reducing and safety, used in a combustible and explosive fluid packaging field.
Description
A kind of all-hydraulic automatic limit assembling device belongs to the hydraulic pressure auto mat, is applicable to the limit dress automatic guidance of limit dress automatic guidance, the especially civil LPG of various fluids.
Present fluid limit assembling device, especially civil LPG is limit assembling device, with the most use is platform scale, show can weight by scale thallium, the arm beam of steelyard fully, artificial valve-off, its weak point are the switches that leans on the subjective by-pass valve control of operating personal fully, and carelessness is arranged slightly, just the possibility overcharge forms accident potential.
Another kind of limit assembling device is the electromagnetism automatic control device, and its weak point is a poor stability, and circuit so must select anti-leak grade and the high electric control element of explosive-proof grade for use, causes cost higher in case the dew electricity can cause the accident at the scene of filling.Jinzhou City, Liaoning Province has developed the metering device trial (demonstration) plant a kind of air operated control limit assembling device: M-2 type autogas auto-filling scale (No. 00000102, the distant word of 87 amount systems), its weak point is that pneumatic element is many, complex structure, the Installation and Debugging difficulty, particularly also need be equipped with air compressor, so installation cost is very high.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of automatic limit assembling device of simple in structure, with low cost, safe and reliable and easy operating is provided.
In the device of the present utility model, adopt a normally closed push buttonvalve, had only when operating personal presses the button, just can make plunger valve and filing gun be in conduction position, begun filling of fluid.Reach limit during loading amount when filling, under the action of gravity that is filled body, move on the plunger, plunger upper part hydraulic oil is pressed into the hydraulic actuating cylinder that links with the freight weight limit counterweight by a check valve, thereby makes filing gun be in closed condition, stops fluid fillers, because this moment, normally closed push buttonvalve cut out, check valve does not allow hydraulic oil to flow backwards, thus when remove filled body after, plunger can not move down the conducting filing gun and cause and fill escape of liquid.
When plunger moved down into position with the complete conducting of filing gun, plunger base contact with barrel bushing hydraulic pipe bottom just, and plunger can not continue to move down, in order to avoid that hydraulic pipe top hydraulic oil and quilt are filled fluid is mixed mutually.When moving on to the position of turn-offing fully with filing gun on the plunger, plunger head contacts with barrel bushing hydraulic pipe top, and plunger moves on can not continuing, and is mixed mutually in order to avoid hydraulic pipe bottom hydraulic oil fills fluid with quilt.In addition, for guaranteeing the seal ring performance of plunger, be provided with three-layer sealed at least circle on plunger, do not mix mutually to guarantee hydraulic oil and to be filled fluid, plunger is filled the fluid no leak when being in complete scram position.
The inlet of plunger valve and the used muzzle that fills can adopt thread connection, use elastic seal ring on the joint interface, so that device of the present utility model and existing filing gun can direct supporting uses.
Device of the present utility model adopts full hydraulic system, by manual activation, is changed by the deadweight that is filled body and to realize automatically shutting down of plunger valve, has saved the power pack section-oil pump in the conventional hydraulic composition.In the device of the present utility model, the weight of freight weight limit counterweight is adjustable, to satisfy the requirement of different limit loading amounts.For when filing gun turn-offs, operating personal can see intuitively that filling weight has reached the limit loading amount, can join a platform scale in device again, and the scale thallium is transferred to the appropriate location, so that reach when limitting loading amount, platform scale can clearly show.
Device of the present utility model is owing to adopted full hydraulic system, and utilization is filled the body deadweight and changes the automatic termination that realizes filling process, has saved hydraulic oil pump, true up really so limit, and simple in structure, easy operating has reduced cost.Because without any power source, so safe and reliable at inflammable and explosive fluid fillers scene.
Accompanying drawing 1 is the fundamental diagram of the utility model device.
Accompanying drawing 2 and accompanying drawing 3 are respectively the fundamental diagram of plunger valve with the filing gun turn-on and turn-off time.
Further specify the utility model below in conjunction with accompanying drawing.
To be filled body-empty steel cylinder 9 and be placed on the hydraulic actuating cylinder 5, the outlet 14 of plunger valve will be withstood on filling on the mouth of steel cylinder 9, under the action of the spring of filing gun 4, be held out against.
The outward winding Open valve of steel cylinder 9, press the button valve then about 1 about 5 seconds, make hydraulic actuating cylinder 6 and plunger valve 3, hydraulic actuating cylinder 5 form path, because this moment, the limit of 29 kilogram weights was adorned counterweight 7 acts on plunger 10 by hydraulic actuating cylinder 6 pressure, act on the pressure and the systemic resistance sum of plunger 10 by hydraulic actuating cylinder 5 greater than the empty steel cylinder 9 of 15 kilogram weights, liquid in the hydraulic actuating cylinder 6 flows in the plunger valve 3 by push buttonvalve 1, plunger 10 is pressed down, make plunger valve 3 conductings fill gun barrel, the beginning autogas fills.
Continuous increase along with liquefied petroleum tolerance in the steel cylinder 9, the pressure that hydraulic oil in the hydraulic actuating cylinder 5 acts on plunger 10 just little by little increases, when filling weight reaches 14.4 kilograms, steel cylinder 9 gross weights reach 29.4 kilograms, and plunger 10 base pressures are moved on the plunger 10 greater than top pressure and systemic resistance sum at this moment, plunger 10 top hydraulic oil are pressed into hydraulic actuating cylinder 6 by check valve 2, plunger valve 3 turn-offs filing gun 4, stops to fill, thereby has realized the purpose that automatic limit is adorned.Meanwhile, the action of the arm beam of steelyard of platform scale 8 shows to have reached filling weight, fills end.
Unclamp the spring of filing gun 4, take the steel cylinder that is full of autogas away.Because this moment, push buttonvalve 1 was in closed condition, check valve 2 does not allow hydraulic oil to flow backwards to plunger valve 3 from hydraulic actuating cylinder 6 yet, is not in the position of closing so plunger valve 3 can not change.
When taking the steel cylinder that has filled away, can click steel cylinder gently downwards, purpose is additional again power on hydraulic actuating cylinder 5, and plunger is moved a bit on again, surpasses the critical closing position, makes it safer, prevents to leak.
In whole filling process, six layers of seal ring 12 that are provided with on the plunger 10 play sealing function, guarantee to flow and press oil not mix mutually with the autogas that is filled, and when plunger valve is in the closed position, prevent gas leak.
The import 15 and the existing filing gun of plunger valve use with thread connection, seal with elastic seal ring 13 on the joint interface.
