Abstract
The utility model relates to a biogas digester negative pressure ball valve. The biogas digester negative pressure ball valve comprises a funnel-shaped valve body and a ball-shaped valve core arranged at the bottom end of the valve body, wherein the left side and the right side of the valve body are respectively provided with a gas pipe, the left side gas pipe is arranged at the upper end of the valve body and is communicated with a gas chamber of a biogas digester, the right side gas pipe is arranged on the bottom of the valve body, one end of the right side gas pipe is connected with the valve core, and the other end of the right side gas pipe is communicated with the atmosphere. A sealing ring is arranged at the connecting position of the inner side of the valve body and the valve core. According to the biogas digester negative pressure ball valve, when negative pressure is formed in the biogas digester, the valve core can rise to open the valve, the atmosphere is made to enter the biogas digester to balance the negative pressure in the biogas digester, and thus potential safety hazards are reduced. Furthermore, the biogas digester negative pressure ball valve is simple in structure and capable of being conveniently and widely applied to the biogas digester.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of biomass pool negative pressure ball valve.
Background technique
Biogas is that organic substance is in anaerobic environment, lower to microorganism zymosis in certain temperature (more than 10C °), concentration (6%) and pH value (pH value 6-7), a kind of inflammable gas producing, cause the poisoning and environmental disruption of personnel for preventing that biogas from leaking, biomass pool needs complete hermetic seal.But in the time taking out biogas residue liquid, will produce negative pressure along with gas chamber volume increases, negative pressure is crossed conference biomass pool vault is produced and destroyed, when serious, even can cause biomass pool tempering and explode, bring potential safety hazard.
In sum, be necessary a kind of simple negative pressure valve of design, in the time that biomass pool produces negative pressure, can in pond, carry atmosphere, to address the above problem.
Model utility content
In view of this, the technical problems to be solved in the utility model is to provide a kind of simple negative pressure valve, in the time that biomass pool produces negative pressure, can in pond, carry atmosphere.
The utility model solves the problems of the technologies described above by following technological means:
Biomass pool negative pressure ball valve of the present utility model, comprise funnel shaped valve body and the spherical spool that is arranged at valve body bottom, described valve body be each side provided with a tracheae, described left side tracheae is arranged at the upper end of valve body, be communicated with the air chamber of biomass pool, described right side tracheae is arranged at the bottom of valve body, and one end is connected with spool, and the other end communicates with atmosphere.
Further, the inner side of described valve body and spool joint are provided with seal ring.
Further, described valve body is made up of stainless steel, and described spool is made of plastics.
Further, described seal ring is made up of elastic deformable material.
The beneficial effects of the utility model: biomass pool negative pressure ball valve of the present utility model, comprise funnel shaped valve body and the spherical spool that is arranged at valve body bottom, described valve body be each side provided with a tracheae, described left side tracheae is arranged at the upper end of valve body, be communicated with the air chamber of biomass pool, described right side tracheae is arranged at the bottom of valve body, and one end is connected with spool, and the other end communicates with atmosphere.The inner side of described valve body and spool joint are provided with seal ring.Thereby the utility model in biomass pool when negative pressure spool can rise and open valve, make atmosphere enter biomass pool, thereby negative pressure in counterbalance cell reduces potential safety hazard.And this apparatus structure is simple, be convenient to be widely used on biomass pool.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1:
Biomass pool negative pressure ball valve of the present utility model, comprise funnel shaped valve body and the spherical spool that is arranged at valve body bottom, described valve body be each side provided with a tracheae, described left side tracheae is arranged at the upper end of valve body, be communicated with the air chamber of biomass pool, described right side tracheae is arranged at the bottom of valve body, and one end is connected with spool, and the other end communicates with atmosphere.Funnel shape valve body is up big and down small, and when normal state, spool, in funnel bottom, seals biomass pool; In the time that biomass pool internal air pressure is too low, spherical spool can rise, thereby breaks sealing state, makes external pressure enter biomass pool, counterbalance cell internal pressure.Tracheae is set and is communicated with biomass pool top air chamber, can regulate biomass pool internal air pressure, the other end is connected with atmosphere and can in the time that spherical spool rises, directly extraneous gas be transported in biomass pool, convenient and swift.
As the further improvement of technique scheme, the inner side of described valve body and spool joint are provided with seal ring.Seal ring is set and makes sealing effect better, in the time of stable gas pressure, can keep the sealing state of biomass pool.
As the further improvement of technique scheme, described valve body 1 is made up of stainless steel, and described spool 2 is made of plastics.The valve body that stainless steel is made is durable in use, and the spool that plastics are made is lightweight, easily rises.
As the further improvement of technique scheme, described seal ring is made up of elastic deformable material.The seal ring that elastic deformable material is made can with spool close contact, prevent the leakage of biogas under normal barometric pressure.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
