Abstract
The utility model relates to a non return circulating valve, in particular to a sludge gas pond feed inlet non return check valve. A support is arranged on a valve body in the shape of a bending tube; a valve cover used for closing a lower opening of the valve body is rotationally connected on the support; an upper opening of the valve body is communicated with a bottom opening of a feed tube of the sludge gas pond. The lower opening of the valve body can realize the automatic cover closing and opening via the valve cover which is rotationally connected. The sludge gas pond feed inlet non return check valve dispenses with the manual handling. As the valve cover is slightly larger than the lower opening of the valve body, the valve cover is tighter and more reliable, which can effectively prevent the overflow of the sludge gas in the pond and the ejection of the sludge liquid in the sludge gas pond from the feed inlet, thus the sludge gas pond can be made sure the safe using, and the peculiar smell pollution can be reduced.
Description
Technical field
The utility model relates to a kind of valve of one-way flow, specifically a kind of unidirectional reverse checkvalve that is used on the methane-generating pit opening for feed.
Technical background
Green energy resource is all being carried out by society now, and biogas is exactly one of them.For preventing in the pond that biogas leaks or has peculiar smell to overflow, the liquid level in the methane-generating pit generally should be higher than the end mouth of opening for feed, to utilize fluid-tight principle sealed feed inlet.There is certain drawback in this sealing means, and the sealing of opening for feed just can't be realized during mouth in the end that is lower than opening for feed at liquid level, and when the pond internal gas pressure is too high, also soiling solution can be ejected.If a valve is installed on opening for feed, just can prevents planting here thing and take place.But in use valve will often open and close, Artificial Control if desired, and complex operation then, and damage easily.
The utility model content
But the purpose of this utility model just provides a kind of unidirectional reverse checkvalve of methane-generating pit opening for feed of automatic open close, to guarantee the safe handling of methane-generating pit, reduces smell pollution.
The utility model is achieved in that makes an elbow-shaped valve body, is provided with supporting member on the elbow-shaped valve body, is rotatably connected to the valve gap of closed valve body end opening on this supporting member.Mouth joins at the bottom of the feed-pipe of the suitable for reading and methane-generating pit of valve body, and the end opening of valve body is positioned at vertical or the oblique slightly position that makes progress, and makes the valve gap that is rotationally connected can rely on the gravity of self to cover the valve body end opening.And during charging, feed liquid relies on self gravity and impulse force just can successfully wash valve gap open, enters in the methane-generating pit.
The key point of the utility model design is to utilize the valve gap that connects in the valve body external rotating that opening for feed is carried out automatic open close, need not manual operation.Because valve gap is located at the valve body outside, therefore the diameter of valve gap just can be a bit larger tham the diameter of valve body end opening, thereby make capping tight more, reliable, both can effectively prevent the excessive of biogas in the pond, soiling solution ejecting in the pond in the time of can avoiding high pressure conditions again from charging, and the pond internal pressure is high more, and the sealing function of valve gap is good more.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, valve body 1 of the present utility model is one 120 °-150 ° a bend pipe, in interior curved tube wall external stability supporting member 3 is arranged, and is provided with the opening support slot in the upper end of supporting member 3.Valve gap 2 is circular lid, and its diameter is a bit larger tham the diameter of valve body end opening.The upper end of valve gap 2 is provided with axostylus axostyle and is connected in the opening support slot on the supporting member 3, and axostylus axostyle can rotate in this opening support slot, thereby has realized being rotationally connected of valve gap and supporting member.Certainly also can adopt alternate manner to realize being rotationally connected of the two.
Join with mouth at the bottom of the feed-pipe for convenient, the upper port of valve body 1 can be made as the form of bell and spigot, is socketed on the end mouth of feed-pipe 6, and is fixedly connected by mode such as bonding.
Preferably be provided with gasket 4 in valve gap 2 inboards, to realize the positiver sealing of valve gap.
Valve gap 2 also can be made into plate-shaped, needs this moment in the valve gap inboard balancing weight 5 to be set, and to increase the weight of valve gap, makes it can fall positiver sealing smoothly after rise after unlatching.
Because of the feed liquid slant acidity in the methane-generating pit, so the utility model can adopt polyethylene or polyvinyl chloride to make.
The utility model also can be used for utilizing on the device that liquid level seals of other, and it is simple in structure, and is easy to use.
Claims (3)
