Abstract
The utility model discloses a breathing valve which comprises a casing, an upper cover, and a valve core arranged in the casing. The valve core comprises a positive pressure cavity and a negative pressure cavity separated through a partition plate; a negative pressure air inlet, a positive pressure air outlet and a valve body connecting flange are arranged on the casing, wherein the negative pressure air inlet is communicated with the negative pressure cavity through a negative pressure inlet connecting pipe; the positive pressure air outlet is communicated with the positive pressure cavity through a positive pressure air outlet connecting pipe; a negative pressure valve plate cap is arranged on the upper cover; the negative pressure valve plate cap corresponds to the top of a negative pressure valve plate; the bottom of the negative pressure valve plate is arranged at the upper part of the negative pressure cavity; a positive pressure valve plate cap is arranged on the partition plate; and the positive pressure valve plate cap corresponds to a positive pressure valve plate arranged in the positive pressure cavity. The breathing valve is made of non-metal material, and completely improves the mode and the structure of an original conventional metal breathing valve on the basis that functions of the breathing valve are guaranteed, thereby optimizing the breathing valve, improving the production efficiency, saving material, and guaranteeing the quality.
Description
Technical field
The utility model relates to a kind of inhalation valve for storage tank.
Background technique
Inhalation valve is the ventilation plant that is fixed on the tank roof, prevents that the interior superpressure of tank or ultravacuum from suffer damage storage tank.Medium in the storage tank has various, has plenty of the Korrosionsmedium of acid or alkali etc.The inhalation valve of traditional metal materials does not just satisfy the needs of relevant department or standard, just must adopt the nonmetallic material manufacturing.And nonmetallic material are such as PP, FRPP, PPH, UPVC, CPVC, PVDF etc., the physical property of himself material determined it can not with the manufacturing process of the inhalation valve same size same structure of traditional metallic material, if according to the inhalation valve of traditional metal the same structure and manufacturing process, will cause waste of material, make difficulty, dimensional accuracy can not guarantee, the shortcomings that equipment intensity is not firm etc.Thereby actual effect and the working life of the product of changing products be can not be guaranteed.
The model utility content
The utility model purpose is to provide a kind of inhalation valve for the defective that prior art exists.
The utility model adopts following technological scheme for achieving the above object:
A kind of inhalation valve of the utility model, comprise housing, loam cake and the spool that is arranged in the housing, described spool is made of malleation chamber and the negative cavity of demarcation strip isolation, the negative pressure inlet mouth is set on the described housing, malleation air outlet and valve body adpting flange, wherein the negative pressure inlet mouth is communicated with negative cavity by the negative pressure entrance sleeve, the malleation air outlet is communicated with the malleation chamber by the malleation connecting tube of giving vent to anger, on cover negative pressure valve plate block be set, the setting corresponding to the top of negative pressure valve plate of negative pressure valve plate block, the bottom of negative pressure valve plate is arranged at the top of negative cavity, malleation valve plate block is set on the demarcation strip, malleation valve plate block be arranged at the malleation chamber in the corresponding setting of malleation valve plate.
Preferably, valve body is set in the described valve body adpting flange connects supervisor, inhalation valve connects supervisor by described valve body and is connected with storage tank with flange.
Preferably, described inhalation valve adopts PP or FRPP or PPH or UPVC or CPVC or PVDF.
The utility model nonmetallic material are made inhalation valve, under the prerequisite that guarantees this product function, have changed pattern and the structure of original common metal inhalation valve fully, thereby have optimized product, have improved manufacturing efficiency, save material, have guaranteed quality.
