Description
Technical field:
The utility model relates to a kind of air-operated safety interlock quick operating valve, can be used for chemical industry, rubber, weaving, building materials, food, pharmaceuticals industry sulfurizing pot, autoclave, freeze in fast opening type pressure container equipment such as machine, medical disinfecting cabinet, belong to the fast opening type pressure container equipment technical field.
Background technique:
The locking of pressure vessel gate is quite important, just in case door lock incessantly, will have an accident, at present, extensively adopt the handle door on the market, a circle is loaded onto a lot of handles around door exactly, by manual lock one by one handle reach the purpose of locking, it is pretty troublesome to operate like this, and labor intensity is bigger.
Summary of the invention:
The purpose of this utility model is exactly a kind of air-operated safety interlock quick operating valve with following function of invention:
1. reach the predetermined interlocked control function of closing the position can booste operation when quick operating valve;
2. when the internal pressure safe release of pressurized container, after throwing off, can open by safety interlock the interlocked control function of door;
3. has 1,2 two warning function that action is synchronous.
For realizing above purpose, the technical solution of the utility model provides a kind of air-operated safety interlock quick operating valve, it is by decorative sheet, baffle plate, box-frame, box plate, gasket, door, handle is formed, its characteristics are, a circle is equipped with n cover and the vertical cylinder that has two sensors of door around baffle plate, cylinder block and door bolt, cylinder is connected on the cylinder block with bolt, piston rod in door bolt and the cylinder is for being threaded, door bolt can be inwardly outer flexible by the action of piston rod, a circle has the groove that is complementary with the door bolt diameter around the door, and the outside of container is equipped with the cylinder operation indicator.
The air-operated safety interlock quick operating valve is shut, to vacuumizing in the container, closed to door when the sensor sensing of door and to have put in place, begin to carry out the latch action, door bolt stretches out in the groove that just in time is inserted into door, and promptly door lock is tight, at this moment, the row of second on cylinder operation indicator green light is bright.If door is under the pretension state, door bolt does not advance.
In like manner, also to have certain degree of vacuum in the container when opening the door, because when in the container pressure being arranged, because the anti-top power of gasket, add the friction of door bolt and door rafter, make door bolt to withdraw from, therefore, to vacuumizing in the container, when another sensor sensing on the door when door bolt can withdraw from, carry out door bolt and withdraw from action, when door bolt fell back on the end, the row of first on cylinder operation indicator red light was bright, and the inhalation valve of opening on the vessel top is dropped a hint in container, when container inner pressure equals barometric pressure, can open door.
In order to make pressurized container work more reliable, the air-operated safety interlock device has been set following alarm point:
1. do not boost in the container when door bolt puts in place fully, report to the police;
2. move back door bolt when container inner pressure is greater than barometric pressure, report to the police;
3. door does not close the pin of entering that puts in place, reports to the police.
The utility model has the advantages that simple in structurely, easy to operate, the safety reliability height is convenient to installation and maintenance.
Description of drawings:
Fig. 1 is air-operated safety interlock quick opening structure figure;
Fig. 2 stretches out sectional drawing for single air-operated safety interlock device door bolt;
Fig. 3 withdraws from sectional drawing for single air-operated safety interlock device door bolt;
Embodiment:
With the freeze dryer is mode of execution, and getting n is 12, promptly determines air-operated safety interlock quick operating valve installation 12 cover cylinders 2, cylinder block 3, door bolt 4.
As shown in Figure 1, be air-operated safety interlock quick opening structure figure, it is by decorative sheet 1, cylinder 2, cylinder block 3, and door bolt 4, baffle plate 5, box-frame 6, box plate 7, gasket 8, door 9, handle 11, cylinder operation indicator 12 are formed.
The selection of material is made decorative sheet 1, cylinder 2, cylinder block 3 for the 316L corrosion resistant plate, door bolt 4, baffle plate 5, box-frame 6, box plate 7, a circle is opened 12 holes of mating with cylinder block 3 end diameter around baffle plate 5, one end of baffle plate 5 and decorative sheet 1 welding, the other end and box-frame 6 vertical welding, the gasket made from silicone rubber 8 is loaded onto in the inboard of box-frame 6, the outside of box-frame 6 box plate 7 of burn-oning.
One end of 12 cylinder blocks 3 is packed in the hole of baffle plate 5, must with baffle plate 5 vertical installations, cylinder 2 usefulness bolts are connected on the cylinder block 3, the piston rod of door bolt 4 and 2 li in cylinder is for being threaded, door bolt 4 can be inwardly outer flexible by the action of piston rod, promote cylinder with source of the gas, see whether door bolt 4 is flexible free.
The selection of material is that the corrosion resistant plate of 316L is made the door 9 that thickness is 120mm, and a circle has the groove 10 that is complementary with door bolt 4 diameters around the door 9, and handle 11 is installed on the door 9, then door 9 usefulness hinges is contained in 6 li of box-frames.
The outside of container is equipped with cylinder operation indicator 12, is equipped with 2 rows, 12 row lampets above the cylinder operation indicator 12, and first row is red light, and second row is green light; In the middle of be equipped with 2 lampets and be respectively a and b.
Two sensors that model is RCA2 have been equipped with on each cylinder 2, two sensors reflect two limit positions of door bolt 4 respectively, when door bolt 4 outwards reaches the groove 10 of end inserting door 9, as shown in Figure 2, sensor green light is bright and feed back to 12 1 signals of cylinder operation indicator promptly second row's a green light is bright, when 12 door bolts 4 all outwards reach the groove 10 of end inserting door 9,12 green lights of second row are bright entirely on the cylinder operation indicator 12, this moment, the b lamp was bright, if have one not work in second row's green light, the b lamp does not just work so, shows that a door bolt 4 does not stretch out in addition; In like manner, when door bolt 4 is received the end inwards, as shown in Figure 3, another sensor red light is bright and feed back to 12 1 signals of cylinder operation indicator promptly first row's a red light is bright, and when 12 door bolts 4 were all received the end inwards, 12 red lights of first row were bright entirely on the cylinder operation indicator 12, this moment, a lamp was bright, if have one not work in first row's red light, a lamp does not just work so, shows that a door bolt 4 is not received at the end inwards in addition.
