Abstract
The utility model belongs to the technical field of a pressure vessel, and is particularly suitable for a quick-open door safety interlocking device for the pressure vessel. The utility model has a structure having the actions of bolt safety and the gas exhaustion safety of a gas storage tank, and the safety interlocking device can be ensured to be safe. The device has flexible action, convenient operation, simple structure and convenient installation and maintenance; the utility model is suitable for the chemical industry, the pharmacy industry, the light industry and the food service industry, and is particularly suitable for the bad environmental occasions of high temperature, moisture and dust.
Description
The utility model belongs to the pressurized container field, is specially adapted to the pressure vessel of quick opening door safety interlock.
According to the statistics of national Department of Labor, in 1980 to 1 in the period of in the pressurized container accident, the fast opening type pressure container explosive accident accounts for 1/3rd, one of reason that causes the accident is to lack effective safety interlock, and the latch insurance for example only is provided.
At the shortcoming of above-mentioned prior art, the purpose of this utility model provides a kind of latch (piston rod) insurance and gas holder loses the pressure vessel of quick opening door safety interlock of gas insurance double insurance effect.
The utility model is implemented by following technical measures, compressed air reservoir 1 is communicated with the entry end of manual two position three-way valve 5 and 15 respectively, 5 and 15 outlet end is communicated with the stingy cylinder 14,17 of single-acting, and the piston rod (being latch) in the stingy cylinder 14,7 of single-acting can contact or disengagement with the mobile of piston with two-position three way machine control selector valve 8, two-position five-way machine control selector valve 9.Compressed air reservoir 1 also is communicated with the entry end of one- way valve 3,21 respectively, 3,21 outlet end is communicated with two-position three way machine control selector valve 8, two-position five-way machine control selector valve 9 respectively, 9 the other end is communicated with the inlet and outlet end of the stingy cylinder 12 of double-action respectively, be communicated with pneumatic-to- current converter 10,8 the other end is communicated with pneumatic-to-current converter 13, and the piston rod (being latch) in the stingy cylinder 12 of double-action is along with the total valve hand wheel of steam can be inserted or throw off to piston moving in cylinder to reach the purpose of control admission.Compressed air reservoir 1 also is communicated with solenoid valve 6 one ends, and 6 the other end is communicated with air filter 4.
Advantage of the present utility model: (one) adopts pressurized air and safety voltage (36V) to operate, and control and display alarm adopt latch insurance and gas holder to lose the effect of gas insurance double insurance, so this device is safe and reliable, flexible movements, easy operating, simple in structure is convenient to installation and maintenance.This device is applicable to and is suitable for the abominable special occasions of environment such as high temperature, humidity, dust especially in chemical industry, pharmacy, light industry and the food service industry.
Description of drawings is as follows:
This device of Fig. 1 gas circuit control principle figure
Fig. 2 master's jar structure schematic diagram
The A of Fig. 3 Fig. 2 is to view
The B of Fig. 4 Fig. 2 is to view
The utility model is further specified as follows below in conjunction with accompanying drawing: be zero-pressure in the main jar 16 preceding jar of starting working, (green light is bright) pressure gauge with electric contact zero and solenoid valve 6 teamworks make pressurized air enter gas holder 1 through filter 4.Pull the moving manual two position three-way valve 15 of deslagging door, make the pressurized air in the gas holder 1 enter the stingy cylinder 7 of single-acting, this moment, piston was moved to the left, its piston rod (latch) withdrawal, and manually switching cylinder 17,18 is closed deslagging door, locks latch hook.Manual once more two position three-way valve 15 cuts off source of the gas, and it is fixed to make latch stretch out pin.After pin put in place surely, latch promoted two-position five-way machine control selector valve 9, and green light puts out, and amber light is bright, and made that piston moves upward in the stingy cylinder 12 of double-action, made pin decide the latch retract of steam main valve, and the deslagging quick operating valve is in the security insurance state at this moment.Open the water valve from the beginning on main jar 16, after adding water dispensing material in giving jar and finishing, the two position three-way valve 5 of manual batch door, make the pressurized air in the gas holder 1 enter the stingy cylinder 14 of single-acting, piston drive piston rod (latch) in it is moved to the left, manual switching cylinder 19,20, the door closure that feeds intake is closed, lock lock hook, manual once more two position three-way valve 5, cut off source of the gas, it is fixed to make latch in 14 stretch out pin, promotes two-position three way machine control selector valve 8, and it is bright to make in the pneumatic-to-current converter 13 green light put out amber light, showing that the door closure that feeds intake has been closed puts in place, and latch is locked.The moving steam main valve 11 of opening of hand-screw is given logical raise steam decoct medicinal herbs in main jar 16 then.At this moment, owing in main jar 16 pressure is arranged, pressure gauge with electric contact zero and solenoid valve 6 automatic joint work all emit (mistake gas) immediately with the pressurized air in the gas holder 1, therefore, even promoting switch, the pneumatic element of fast-open door panel and safety installations, misoperation also can't move the quick operating valve of not opening.Cooked Chinese medicine, manual-lock steam main valve 11 stops to pressurize in main jar 16, open Decompression valves, make a main jar internal pressure reduce to zero (relative pressure, and have light to show), by pressure gauge with electric contact and solenoid valve 6 automatic teamworks, make in the gas holder 1 the entrance pressure air that contracts, locking steam main valve 11, hand switch 5 and 15, throw off latch, open the quick operating valve that feeds intake earlier, open the deslagging quick operating valve again, the dregs of a decoction of draining are finished the decoct medicinal herbs process one time.
