Description
Technical field
The utility model relates to valve field, particularly relates to a kind of inhalation valve.
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 inhalation valve, is characterized in that structure is simple, good seal performance, valve disc movement sensitive.
The utility model is achieved through the following technical solutions:
A kind of inhalation valve, comprise bonnet, valve body, valve seat, valve body is provided with exhale tube, suction pipe, described valve body is provided with the first valve opening, the second valve opening, first valve opening is communicated with valve inner and exhale tube, second valve opening is communicated with valve inner and suction pipe, the first valve opening, the second valve opening is respectively arranged with the first valve disc, the second valve disc; First valve disc is provided with guide rod, and guide rod is inserted in the first guide cylinder on bonnet, and when being connected to the valve inner pressure increase on equipment, the first valve disc is by jack-up, and guide rod moves up and down along the first guide cylinder; Second valve disc is provided with guide rod, and guide rod is inserted in the second guide cylinder, and when device interior pressure reduces, the power that draught head is formed is from jack-up second valve disc below the second valve disc, and the second valve disc moves up and down along the second guide cylinder; Described second guide cylinder is positioned at suction pipe; The first rubber ring is provided with between first valve disc and the first valve opening, first rubber ring is fixed on the boss of the first valve opening, first valve disc there is the real groove of joining with the first rubber ring, in like manner, the second rubber ring is provided with between second valve disc and the second valve opening, second rubber ring is fixed on the boss of the second valve opening, the second valve disc has the real groove of joining with the second rubber ring.
Described first guide cylinder, the second guide cylinder are arranged porose.Hole on first guide cylinder, the second guide cylinder can prevent tired gas in the first guide cylinder, the second guide cylinder, affects the motion of the first valve disc, the second valve valve disc.
The cross section of described first rubber ring, the second rubber ring is Hexagon or ellipse.
Compared with prior art, the beneficial effects of the utility model are: the utility model by being provided with groove on the first valve disc, the second valve disc, groove and the first rubber ring be fixed on the first valve opening, the second valve opening, the second rubber ring adaptation, strengthen the sealing effect of contacting point, tired gas can be avoided in hole on first guide cylinder, the second guide cylinder, ensures that the first valve disc, the second valve plate movement are flexible.
