Abstract
The utility model relates to an accessory member of an accumulator, which is a safety stop valve. The valve is composed of a valve body, a screen mat and a fluorosilicone rubber plug, wherein, the valve body is screwed with the screw thread of the accumulator. The utility model is characterized in that the cavity of the valve body (1) is provided with the fluorosilicone rubber plug (2) having the shape of quadrangular prism body, the lower end of the fluorosilicone rubber plug is pressed on a through-hole being once through to the accumulator, the upper end is covered with a circular mat and the large clip cap of the cap-shaped nut (4), and the middle of the clip cap is provided with a small hole. The clip cap is screwed with the screw thread arranged in the mouth part of the cavity, and a concave groove is arranged in the upper part of the cavity, and the filter screen mat (5) is arranged in the concave groove. The utility model overcomes the defect that the prior art has short service life for the stop valve is easy to be bad, and the valve has the advantages of long service life and safety.
Description
The utility model relates to an associate member on the storage battery, belongs to the technological improvement of safe limit stop valve, a kind of limit stop valve.
Safe limit stop valve is the critical component of the normal operation of sealed type lead acid battery, it must have excellent ageing-resistant performance can guarantee just under the foul smell that produces and the acid mist etch that its open and close valve pressure value is still within zone of reasonableness in 10 years in battery, otherwise can make battery produce serious " tripe expands " or too early " solid carbon dioxide " phenomenon, battery was lost efficacy in a short time, and the quality of ageing-resistant performance depend primarily on rationality, the science of selecting for use of rubber clone and structure.Its anti-ozone and acidproof binomial index are mainly considered in the use of safe limit stop valve, therefore, safe limit stop valve will consider that promptly material therefor also will consider rationality, the science of its structure shape, what existing safe limit stop valve adopted is that neoprene is made safety helmet, structure is also unreasonable, reach not anti-ozone far away, acidproof binomial index exists not long shortcoming in working life.
The purpose of this utility model is to improve the material of original safe limit stop valve and improves the structural design of Safety performance, provides the safe limit stop valve of a kind of more anti-ozone and acidic fog resistance, reaches still in the reasonable scope novel limit stop valve of its open and close valve pressure value in 10 years.
The purpose of this utility model is achieved in that this non-maintenance secondary battery safety limit stop valve, by valve body, filtering gauze pad and fluorosioloxane rubber plug forms, valve body and storage battery are spun by screw thread and the storage battery on the valve body outer ring step, valve body is the circular injection molding body that generation step cutting pattern is arranged, its outer step is provided with screw thread, be provided with inner chamber in the valve body, the inner chamber oral area is provided with internal thread equally, and be provided with the spill circular trough on inner chamber top, be provided with the through hole straight-through in the middle of the intracavity bottom with storage battery, be provided with one four prismatic cylinder fluorosioloxane rubber plug in the chamber, its lower end surface is pressed on the through hole that leads directly to storage battery, and its upper end is stamped a circular pad and is spun by Ka Gai and body cavity oral area screw thread that big acorn nut constitutes, also establishes an aperture in the middle of the card lid, and in card upper part of the cover spill circular groove, the filtration gauze pad is set, constitute safe limit stop valve.
To achieve these goals, fluorosioloxane rubber plug in the safe limit stop valve inner chamber is made up of carbon black filler and fluorosioloxane rubber, and be arranged to the cylinder of four fusiformis, reached the i.e. sealing purpose of ventilation again, solved unreasonable structure in the prior art, working life short, can not with the shortcoming of storage battery with the longevity.
The utility model is compared with the prior art because to have adopted the fluorosioloxane rubber that adds eight carbon black fillers be material with improved project organization, making working life than adopting neoprene is that the life of product of raw material is brought up to more than 10 years from original 2-3, its elasticity and tension force and open and close valve pressure value are still within reasonable range, because safety installations such as the gauze pad of filtration are arranged, better tightness, storage battery can " do not expand tripe " or " solid carbon dioxide ", under the normal situation about using, there are not electric liquid or acid mist to overflow, before the end-of-life, storage battery need not safeguarded, has guaranteed long-life normal operation, and is safe and reliable.
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Fig. 1 structural representation of the present utility model.
Fig. 2 fluorosioloxane rubber plug of the present utility model schematic representation.
Fig. 3 the utility model safety limit stop valve planimetric map.
The elevation of Fig. 4 the utility model fluorosioloxane rubber plug.
Referring to accompanying drawing, adopt injection moulding process, be injection molded into valve body (1), valve body (1) is generation to have step cutting pattern to be divided into three layers cylindrical body up and down, the outer step of its second layer is provided with screw thread, be provided with inner chamber in the valve body (1) and the inner chamber oral area is provided with the spiral shell mosquito, inner chamber top is provided with the spill circular trough, is provided with vent in the middle of the intracavity bottom, the fluorosioloxane rubber plug (2) of four prismatics places in the chamber, on be stamped a circular pad and big acorn nut shape Ka Gai (4) and filter gauze pad (5), be provided with an aperture in the middle of the Ka Gai (4), in order to guarantee the ageing-resistant and acid mist of rubber stopper, adopt fluorosioloxane rubber and add the material of eight carbon black fillers, thereby guaranteed the long lifetime of product.
Claims (2)
1. non-maintenance secondary battery safety limit stop valve, by valve body, filtering gauze pad and fluorosioloxane rubber plug forms, it is characterized in that valve body (1) and storage battery screw thread spin, valve body (1) is the circular injection molding body that generation step cutting pattern is arranged, its outer step is provided with screw thread, valve body is provided with inner chamber in (1), the inner chamber oral area is provided with internal thread, and be provided with the spill circular trough on inner chamber top, be provided with the through hole straight-through in the middle of the intracavity bottom with storage battery, be provided with one four prismatic cylinder fluorosioloxane rubber plug (2) in the chamber, its lower end surface be pressed in the straight-through through hole of storage battery on, circular pad is stamped in its upper end and the Ka Gai (4) that is made of big acorn nut spins with valve body (1) inner chamber oral area screw thread, in the middle of the card lid aperture also is set, and filtration gauze pad (5) is set in the Baltimore groove on Ka Gai (4) top.
2. limit stop valve according to claim 1 is characterized in that, fluorosioloxane rubber plug (2) is made up of carbon black filler and fluorosioloxane rubber, and is arranged to the cylinder of four prismatics.
