Description
Technical field
The present invention relates to a kind of automatic spacing safety valve for biogas pool slag pumper.
Technical background
Limit stoper in the existing biogas pool slag pumper generally only prevented the suction effect, or the safety valve effect only arranged, prevented to inhale to control and irritated liquid level (face) excessive height that sucks liquid in the body, sucked the liquid overfill in the body, and caused liquid to suck vacuum pressure pump in order to avoid irritate.This limit stoper is difficult to satisfy and had both prevented suction, plays the effect of overvoltage protection again, can automatic vent when producing gas pressure surpassing certain value in irritating body.
Summary of the invention
The present invention seeks to overcoming the deficiency of above-mentioned prior art, provide a kind of can control irritate the liquid level that sucks liquid in the body, again can self-bleeding automatic spacing safety valve for biogas pool slag pumper.
The present invention includes ball float basket, ball float, top flat, push rod, set screw nut and air pressure valve assembly.The air pressure valve assembly comprises push rod, valve seat, locking nut, safety valve spring, valve gap, guide rod and flexible glue pad.Valve seat is one the cylindric of step, middle slightly thick, and both sides are omited thin and outside thread is arranged; Valve gap is a cylindric hollow tubular of two-part, and epimere has the thin circular hole of smooth central authorities, and the hypomere circular hole is thicker, and in the circular hole one section has internal thread.Locking nut is installed on by internal thread to have on the externally threaded valve seat, and valve gap is positioned at above the locking nut, and valve gap is screwed in by internal thread has externally threaded valve seat top, and tightens.Guide rod and push rod all are cylindric, and guide rod is inserted in the thin circular hole of valve gap central authorities, endoporus with internal thread of guide rod; Push rod is one pluckings and long, is inserted in the valve seat, and the other end is thin and short and outside thread arranged; Guide rod links together by the outside thread of internal thread and push rod.Flexible glue pad and copper packing are housed between guide rod and the push rod.Top flat is fixed on the push rod lower end.On the guide rod in valve gap safety valve spring is housed; It is oval tank body top that set screw nut is positioned at cross section, and set screw nut is welded on the tank body, and runs through tank wall; Valve seat is screwed on the set screw nut by outside thread, is provided with the flexible glue pad between valve seat and the set screw nut.The ball float basket is housed below the valve seat in tank body, and the ball float basket comprises four vertical rods of baffle plate and front, rear, left and right, and four vertical rods surround tubular jointly, and ball float is loaded in the ball float basket.The vertical rod upper end is connected the tank body below by articulating screw, and the vertical rod lower end is welded on the disk shape baffle plate, and ball float adopts hollow stainless steel material to make.
Vacuum pressure pump links to each other with tank body by pipe; when vacuum pressure pump is in the working state of suction, produce negative pressure in the sealed shell of tank, liquid is sucked in the tank body by inlet; liquid rises to liquid level line in tank body; ball float upwards promotes top flat under liquid effects and push rod makes progress, and the compressing secure valve spring upwards boosts guide rod; open the safety-valve; tank body is communicated with atmosphere eliminates negative pressure, stops to suck liquid in the tank body, and vacuum pressure pump is effectively protected.When vacuum pressure pump is in the exhaust work state; produce malleation in the tank body; biogas pool slag pumper is in pressure exhaust state; when the tank body internal pressure is elevated to certain value (0.2MPa); the gas pressure that acts on the top flat will be passed on push rod, guide rod and the safety valve spring; open the safety-valve, gas in the tank body is drained, play the overvoltage safety protection effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, top flat, 2, push rod, 3, valve seat, 4, locking nut, 5, the flexible glue pad, 6, copper packing, 7, safety valve spring, 8, valve gap, 9, guide rod, 10, the flexible glue pad, 11, set screw nut, 12, tank body, 13, articulate screw, 14, vertical rod, 15, ball float, 16 baffle plates.
Embodiment
The ball float basket, articulate screw 13, tank body 12, set screw nut 11, push rod 2 and top flat 1 and all make with Common Straight Carbon Steel.Safety valve spring 7 usefulness rustproof spring steel silks are made, and its quality is the assurance of threshold sensitivity.Guide rod 9, valve gap 8, locking nut 4 and valve seat 3 usefulness nylon are made, and copper packing 6 usefulness tin-phosphor bronze sheets are made, and flexible glue pad 5,10 usefulness soft rubbers are cast.Ball float 15 adopts the stainless steel hollow spheres, causes automatic spacing safety valve malfunctioning in case get rusty.Set screw nut 11 adopts state's tender.Vertical rod 14 upper ends are connected on the little lug that welds tank body 12 belows by articulating screw 13.
Under the condition of negative pressure, open the safety-valve to overcome making a concerted effort of tank body 12 interior negative pressure and safety valve spring power in the tank body 12.Under the nominal operating condition, negative pressure value is generally-40KPa in the tank body 12, the about 2.5kg that makes a concerted effort that calculates.Therefore required ball float 15 diameters should be greater than 170mm, or volume is more than 2.6 liters.
Should adjust on the platform at safety valve before using and adjust.Step is: earlier air pump air pressure is transferred to 0.2MPa, rotates valve gap 8 safety valve of the present invention is transferred to closed condition, the spin-up valve gap 8 that slowly makes progress is only opened to safety valve of the present invention, with locking nut 4 lockings.Air pump air pressure is turned down safety valve close, again air pump air pressure is transferred to 0.2MPa, safety valve of the present invention is opened automatically, confirms to mix up.As not opening or open in advance, need repeat above step and adjust again, till mixing up.Whole adjustment process is equivalent to the process of a simulation Environmental Conditions, and only this environment is adjusted the platform simulation by safety valve, and purpose is to adjust the compression degree of safety valve spring 7, makes it can open reliably under the 0.2MPa Environmental Conditions.
