Abstract
The utility model relates to a sleeve sealing ring for an equipment hatch of a nuclear power station and belongs to mould pressed products. The sleeve sealing ring is composed of a hollow inflating belt with a concave cross section and two end sockets, wherein a metal inflating nozzle is embedded at the top of one of the end sockets and is communicated with the inner chamber of the hollow inflating belt with the concave cross section. The technical key points of long length, hollow structure, uniform wall thickness and glue bonding firmness of the metal inflating nozzle and the end sockets are achieved. The air tightness is excellent; the design performance of end products and the environment use demand are met; the domestication is realized.
Description
Technical field
The utility model belongs to rubber molded product.
Background technique
The gate of Nuclear Power Station reactor unit equipment factory building is vertical gate, is the sealing of falling at ordinary times.In the nuclear power generating sets maintenance period of carrying out every year, gate needs to open, so that maintenance of equipment or change the turnover of transporting of parts.Equipment gate doorframe is groove, and groove is embedded in matrix section hollow rubber gas-flow closure circle.When gate is closed, insert in the groove of rubber seal on door limit, and seal ring inflation prevents that to reach strict sealing nuclear pollution beyond the region of objective existence from letting out.At present, greatly develop under the background of the nuclear power energy in country, China is developing nuclear power generating sets and the relevant matching parts of independent intellectual property right always, so equipment gate sleeve seal circle has also been carried out to production domesticization research.
Summary of the invention
The purpose of this utility model is for domestic nuclear power provides equipment gate special (purpose) rubber seal ring, its key problem in technology be to solve product big-length, hollow structure, product wall thickness evenly, metal charging air inlet and termination colloid is bonding firmly, product has good tightness.
The technological scheme adopting is to provide a kind of hollow inflatable band by matrix section and two terminations form, and the top of one of wherein said termination is embedding has metal charging air inlet to be communicated with the hollow inflatable band inner chamber of matrix section.
The utlity model has higher tensile strength and elongation percentage, wall thickness is even.When equipment factory building closing gate, by charging air inlet, to seal ring, inflate, under certain pressure, can guarantee that metal mouth and rubber adhesion are firm, product has good tightness, can not there is gas leak phenomenon, the material that contains radiation dose can not be leaked outside, guarantee safety, meet finished product design performance and dreamland usage requirement.
Accompanying drawing explanation
Fig. 1 the utility model termination portion sectional view,
1-matrix section rubber seal, 2-metal charging air inlet, 3-hollow inflatable chamber.
Embodiment
Below in conjunction with accompanying drawing, describe structure of the present utility model and preparation process in detail.
Select ethylene propylene diene rubber and relevant compounding ingredient to be prepared into elastomeric compound, elastomeric compound is rolled into film, cut out film and moulding matrix section rubber seal (1) on core rod, semi-finished product after moulding are put into mould, adopt and fall to press the mode of sulfuration to vulcanize on vulcanizer, when length reaches after design size requirement, scutching is carried out in the inner glue layer surface of product one end crown portion.After metal charging air inlet (2) brushing adhesive stick, put into the termination after scutching, use joint mold to vulcanize position, seal ring termination, metal charging air inlet (2) and termination colloid are fixed, guarantee the tightness of product.
Claims (1)
1. used in nuclear power station equipment gate sleeve rubber seal, consists of hollow inflatable band and two terminations of matrix section, and it is characterized in that the top of one of described termination is embedding has metal valve to be communicated with the hollow inflatable band inner chamber of matrix section.
