Description
Technical field
The utility model relates to valve field, particularly relates to a kind of for equipment such as storage tanks, keeps the inhalation valve that device interior pressure is balanced with atmospheric pressure.
Background technique
Inhalation valve safeguards that cartridge gas pressure balances, and reduce the energy-saving safe product of medium volatilization, inhalation valve makes full use of the bearing capacity of storage tank itself to reduce media discharge, and its principle utilizes the weight of positive/negative-pressure valve disc to control exhaust malleation and the intake negative-pressure of storage tank; When extracting medium out outward toward tank; make the pressure drop of the tank internal upper part gas space; when reaching the operation negative pressure of inhalation valve; the negative pressure valve disc backing down inhalation valve backs down by the air outside tank; ambient atmos is made to enter in tank; make the pressure in tank no longer continue to decline, allow in tank with the air pressure balance outside tank, protect the safety installations of storage tank.The working principle of inhalation valve is that the pressure of the tank internal upper part gas space is raised, and when reaching the operation malleation of inhalation valve, pressure valve is backed down when supplementing medium in tank, and gas, from the effusion of inhalation valve expiratory port, makes tank internal pressure not continue to increase; Air outside tank will back down the negative pressure valve disc of inhalation valve.
Model utility content
The utility model provides a kind of inhalation valve, is characterized in that the switching motion of inhalation valve is sensitive, the good sealing effect of spool and valve opening.
The utility model is achieved through the following technical solutions:
A kind of inhalation valve, comprise upper cover, valve body, suction valve chip, expiration valve block, air-breathing valve opening, expiration valve opening is had in described valve body, suction valve chip coordinates with air-breathing valve opening, and expiration valve block coordinates with expiration valve opening, described upper cover and valve body assembly, bolt and nut is had to fix between upper cover and valve body, on cover and be provided with fixed body, fixed body is provided with the guide rod connecting suction valve chip and expiration valve block, suction valve chip and expiration valve block are through guide rod and can slide up and down along guide rod; The fitting surface of described suction valve chip and air-breathing valve opening and the fitting surface of expiration valve block and expiration valve opening are the conical surface.
Described suction valve chip, expiration valve block are provided with the guide sleeve coordinated with guide rod, and guide sleeve is fixedly connected with suction valve chip, expiration valve block.
Be provided with rubber ring between described suction valve chip and air-breathing valve opening, between expiration valve block and expiration valve opening, be provided with rubber ring.Rubber ring enhances the sealability at sealing position, prevents from revealing.
Described valve body is provided with rain shade, and the gas flow passage port on rain shade is provided with filter screen.Filter screen can filter the impurity in the air entered in valve body.
Described inhalation valve is fixedly connected with equipment by base.
When device interior pressure increase, the pressure ratio atmospheric pressure of device interior is large, the power that draught head is formed compresses suction valve chip from top, suction valve chip and air-breathing valve opening closely cooperate, meanwhile, the power that draught head is formed is from jack-up expiration valve block below expiration valve block, and expiration valve block moves upward along guide rod, gas is discharged to outside in valve body, and the pressure in equipment reduces until balance with barometric pressure.
When device interior pressure reduces, the power that the pressure difference of atmospheric pressure device inside is formed compresses expiration valve block above expiration valve block, and expiration valve block and expiration valve opening closely cooperate, simultaneously, suction valve chip is by jack-up, and air access arrangement is inner, and device interior pressure raises until balance with barometric pressure.
Compared with prior art, the beneficial effects of the utility model are: the fitting surface of suction valve chip of the present utility model, expiration valve block and air-breathing valve opening, expiration valve opening is the conical surface, sealing surface place is provided with rubber ring, thus good sealing effect, No leakage, guide rod guides the movement direction of valve block, ensures that valve block opens and closes sensitive.
