Description
Technical field
The utility model is related to reactor vacuum valve field, more particularly, to a kind of vacuum extraction valve of reactor.
Background technology
The broad understanding of reactor has the container physically or chemically reacting, by joining with parameter to the structure design of container
Put, realize heating, the mixture function of evaporation, cooling and low high speed of technological requirement.
Reactor is widely used in oil, chemical industry, rubber, agricultural chemicals, dyestuff, medicine, food, for complete sulfuration, nitrification,
The pressure vessel of the technical process such as hydrogenation, hydrocarbonylation, polymerization, condensation, such as reactor, reaction pot, decomposition pot, polymeric kettle etc.；Material
Matter typically has carbon manganese steel, stainless steel, zirconium, Ni-based (Kazakhstan, Monel, inconel) alloy and other composite.
Aborning, due to the needs of reaction condition, reactor needs to pump the air of inside, makes the reactor after sealing
Inside reach predetermined vacuum level.
Existing reactor is all by connecting vavuum pump by reaction kettle for vacuumizing, during vacuumizing, reactor
Upper not setting vacuum extraction valve, generally requires to maintain the vacuum in reactor, reactor through normally open vavuum pump
Vacuum valve is not set and vacuum lead between, and not, the time is slightly longer, still has a small amount of gas for sealing air-tightness
Entering in reactor, once there being air to enter in reactor, needing to be again started up vavuum pump again.
Utility model content
The purpose of this utility model is to provide a kind of vacuum extraction valve of reactor, to solve above-mentioned technical problem.
Technical problem to be solved in the utility model employs the following technical solutions to realize：
A kind of vacuum extraction valve of reactor it is characterised in that：Including valve body, valve body has upper cavity and lower chamber, institute
State upper cavity upper end and be provided with valve, valve upper end is provided with gas nozzle cap, in described epicoele body, be horizontally disposed with pressing plate, on pressing plate
End connects depression bar, and depression bar, longitudinally through valve, is provided with (the first back-moving spring in described valve, (the first back-moving spring is enclosed within depression bar
On, it is provided with filter screen in described cavity of resorption body, separate and be provided with pore on upper cavity and the dividing plate of lower chamber, be provided with close in pore
Envelope valve block, sealing valve plate is made up of with the valve rod being connected to diaphragm seal lower end diaphragm seal, and diaphragm seal is placed in epicoele body, and valve rod is indulged
To through pore, described valve rod is cased with second back-moving spring, described valve rod lower end and second back-moving spring are placed in cavity of resorption body,
Described pressing plate is Turbogrid plates.
The lower end of described valve body is provided with flanging, and flanging is bumped in the kettle of reactor.
Valve bottom is provided with the sieve aperture baffle plate of ventilation, and depression bar passes through sieve aperture baffle plate, and (the first back-moving spring is placed in sieve aperture gear
On plate, depression bar is provided with projection, as the upper limit block of (the first back-moving spring, in the presence of (the first back-moving spring,
Pressing plate is in vacant state in epicoele body, and only when gas nozzle cap covers, pressing plate is pressed downward by depression bar, so that pressing plate is pressed in close
On envelope valve block, good sealing effect.
It is to threaded between gas nozzle cap and valve, or engaged by buckle.
The beneficial effects of the utility model are：
The vacuum extraction valve of the reactor that the utility model provides, has the advantages that air-tightness is good, sealing valve plate upper end is not
Only it is subject to atmospheric pressure, be also subject to the pressure of pressing plate it is ensured that the sealing effectiveness to pore for the sealing valve plate, when gas nozzle cap is opened,
Pressing plate rises automatically, and sealing valve plate is discharged, you can be normally carried out vacuum pumping, using very convenient.
