Description
Technical field
The present invention relates to improvement, realize integratedly filling, cut-out and the integrated function of exhaust, belong to liquid chlorine manufacturing enterprise liquid chlorine filling technical field the conventional filling valve of liquid chlorine filling system.
Background technique
Chlorine is important basic chemical industry raw material, the derived product of chlorine reaches thousands of kinds, be widely used in industries such as petrochemical industry, agricultural chemicals, medicine, weaving, light industry, electric power, metallurgy, defence and military, chemical building material, in the national economic development in occupation of critical role.In addition, chlorine also is the main raw material of drinking water treatment in people's daily life, environment disinfected and household chemicals, and is closely bound up with people's lives.Whole nation liquid chlorine output is gone beyond 2,000 ten thousand tons of high pointes, occupies the first in the world for several years running.
The production of industrialization chlorine is that electrolytic sodium chloride (potassium chloride) also purifies the chlorine of gaseous state and cryogenic liquefaction is a liquid chlorine, and liquid chlorine is convenient to store, is packed, transports and use; The liquid chlorine packaging container generally adopts the liquid chlorine gas cylinder, fills quality 1000kg/ bottle; Chlorine---hypertoxic chemistry poisonous substance in case accidental release may cause the pollution of air, water body and soil, may cause that the contact personnel poison and even death.
The liquid chlorine filling process has certain danger, and reduce leakage, reduce hand labor intensity, operate miss and at utmost automation, be the direction that current urgent need is improved and improved.
What the liquid chlorine cylinder filling adopted at present is that many valves series and parallel pipeline connects, the single valve manually-operable fills technology.As shown in Figure 1,1 is feeding valve, and 2 is cut-off valve, and 3-1,3-2 are filling valve, and 4 is outlet valve, and 5 is the liquid chlorine gas cylinder.
Automatically control section only comprises setting by the electronics weighing apparatus and weighs and the start signal output cut-off valve stops to fill, and all the other valve operations are manually.
Operation is prepared: drive feeding valve, close cut-off valve, close filling valve, close outlet valve.
Operating process: 1. manually connect the liquid chlorine empty bottle; 2. manually opened cylinder valve; 3. the manually-operable button is opened cut-off valve; 4. manually opened filling valve fills; 5. when reaching established amount (the electronics weighing apparatus outputs signal to PLC), cylinder filling closes cut-off valve automatically; 6. manual-lock cylinder valve; 7. manual-lock filling valve; 8. manually opened outlet valve is vented to vacuum absorption device; 9. unload the heavy bottle of liquid chlorine; 10. closing outlet valve finishes once and fills; The process that repeats then 1.～is 10. carried out new filling.
Problem and defective: although Weighing and cut-off valve are chain by PLC control, the valve march-past arranges that node is many, and the loaded down with trivial details labor intensity of manually-operable valve is big, and it is bigger that pipeline connects the static seal point possibilities of leaking more, and manually misoperation is still within the bounds of possibility.
Summary of the invention
The present invention wants the technical solution problem to be: at the above-mentioned shortcoming of prior art, provide a kind of liquid chlorine filling special valve, collection fills, cut-out and degassing function are one, reduces labor intensity and has improved safety reliability.
In order to solve above technical problem, liquid chlorine filling special valve of the present invention, it is characterized in that comprising: valve body with cylindric chamber, cooperate and rotating cylindric spool with described valve chamber, described valve body has at least one pair of liquid chlorine material feeding mouth, the liquid chlorine discharge port, and relief opening, described cylindric spool offers and can make the liquid chlorine material feeding mouth, the through hole of liquid chlorine discharge port UNICOM, the side of cylindric spool has the axial groove corresponding with the liquid chlorine discharge port, described axial groove is communicated with relief opening, and with UNICOM's liquid chlorine material feeding mouth, the through hole of liquid chlorine discharge port cuts off, the beeline at the outlet side of through hole to axial groove edge is provided with sealing configuration greater than the diameter of liquid chlorine discharge port near spool one side between valve rear end and the cylindrical spool.
This liquid chlorine filling special valve is realized the switching of each state by rotational valve core to specified angle, the Security reliability is higher, the production accident of avoiding tradition to cause because of operate miss, industrial control is easy to realize, thereby make the automated job of special valve become possibility, greatly reduce working strength of workers.
In this special valve, when the through hole two ends are aimed at liquid chlorine material feeding mouth, liquid chlorine discharge port respectively, this special valve is in (filling) state of opening; When the liquid chlorine discharge port by the through hole outlet side to the spool sidewall shutoff between the axial groove, this special valve is in (cut-out) state of cutting out; Aim at the liquid chlorine discharge port when axial groove, this special valve is in exhaust condition; When axial groove was aimed at the liquid chlorine material feeding mouth, this special valve was in vehicle stop state.
The present invention has thoroughly changed the pure manual work pattern that tradition utilizes cut-off valve (1), filling valve (2), outlet valve (1) to carry out operation, and its collection fills, cut-out and degassing function are one; Can substitute former manually operated valve one by one by actuator's procedure operation, reduce labor intensity, improve safety reliability, be specially adapted to the isolated plant of liquid chlorine cylinder filling.
Further, the valve core inside of special valve of the present invention is provided with the exhaust passage, and described axial groove is communicated with the valve body relief opening through the exhaust passage, and described exhaust passage and through hole cut off.Particularly, described exhaust passage comprises radial hole, the axial bore that links to each other successively, and described radial hole is connected with axial groove, and the axial bore outer end is towards the valve body relief opening, and relief opening is positioned at the valve body front end, and is corresponding with the front end of cylindrical spool.
When axial groove was aimed at the liquid chlorine discharge port, the liquid chlorine discharge port was communicated with relief opening.Relief opening is connected with vacuum equipment, and liquid chlorine discharge port to the liquid chlorine between the liquified chlorine gas bottle valve is vaporized because of air pressure reduces, and successively through axial groove, radial hole, axial bore, discharges from relief opening.
For the ease of filling of liquid chlorine, in the liquid chlorine filling special valve of the present invention, paired liquid chlorine material feeding mouth, the center line of liquid chlorine discharge port are located along the same line and are vertical with cylindrical spool, and described through hole is vertical passes the center spool line.
Move axially in rotation process for fear of spool, in this liquid chlorine filling special valve, the spool front end edge is circumferentially offered restraining groove, and the valve body relevant position is provided with at least two thrust screws perpendicular to spool, described thrust screw circumferentially evenly distributes along spool, and its front end is positioned at restraining groove.
