Automatic alarm composite exhaust valve
Technical field
The utility model relates to a kind of automatic alarm composite exhaust valve, belongs to sewage treatment supplementary equipment technical field.
Background technique
Outlet valve is installed on the peak of sewage conduct more or has the position of holding one's breath, by gas in drain, reach the effect of dredging pipeline, to guarantee the normal work of sewage conduct, otherwise pipeline is prone to vapour lock, cannot meet the requirement that water capacity, especially when there is power failure, termination of pumping pipeline, while there is negative pressure, very easily cause pipe vibration or break, the setting of outlet valve can, rapidly by air intake pipe, prevent pipe vibration or break.Conventional outlet valve mainly by bottom valve, valve body, be installed on the guide rod ball float in valve body, the plunger tip that is provided with little relief opening, large relief opening and valve gap etc. and form, the defect that this structure exists is following several respects:
(1) rubber band in outlet valve driving mechanism plays is the effect of sealing, but impurity and residue in sewage is more, in the transmission by ball float pressure, can stick on rubber band, causes the poorly sealed generation of rubber band to be leaked; And adopting stainless steel filtering net impurity can be blocked in stainless (steel) wire outside, the impurity adhesion in rubber band has reduced, but due to inevitably accumulated impurity and residue in exhaust valve float ball, makes outlet valve still occur in use for some time leakage phenomenon.
(2) when inhomogeneous, the start-stop pumping frequency of sewage collecting amount is numerous, easily there is Seepage; and ne-leakage protective gear; and seepage very easily causes serious Environment Pollution Event; therefore, in exhaust process, must have personnel to guard, and the probability that seepage event occurs cannot be assessed; automaticity is low; cost of labor is high, cannot realize auto-alarm function, and the property monitored is poor.
(3) adopt unitary valve body structure, while assembling large quantity of air in valve body, can discharge fast, but micro-air is when assemble, effect is not remarkable, controls inaccuracy.
(4) ball float adopts single guide rod structure, locates not accurate enough phenomenon, makes relief opening sealability bad, often has sewage and leaks from sealed mouth spray, thereby cause impurity and residue to block exhaust valve float ball driving mechanism.
Based on this, make the utility model.
