Abstract
<B>HIDROVáLVULA<D> a presente patente de invenção da hidroválvula tem a finalidade de fazer com que o ar acumulado nas tubulações <B>(12)<D> saia para a atmosfera. A hidroválvula acima citada é constituída de um corpo dividido em duas partes, superior <B>(1)<D> e inferior <B>(7)<D>. Tendo no seu interior uma bóia de flutuação <B>(6)<D> que fará o trabalho de bloqueio da passagem de fluídos para a atmosfera através da área de escape <B>(5)<D>. O material usado para sua fabricação deve seguir as normas da ABNT.<B> HYDROVALVE <D> the present patent for the invention of the hydrovalve has the purpose of causing the accumulated air in the pipes <B> (12) <D> to escape into the atmosphere. The water valve mentioned above consists of a body divided into two parts, upper <B> (1) <D> and lower <B> (7) <D>. With a float <B> (6) <D> inside it that will do the job of blocking the passage of fluids into the atmosphere through the exhaust area <B> (5) <D>. The material used for its manufacture must follow ABNT standards.
Pollutant dispersant comprising about 42.9% by weight of water, 14.3% of plasticizer that is 2,2,4-trimethyl-1,3-pentanediol diisobutyrate and 14.3% of surfactant wetting agent which is a block copolymer of ethylene oxide / propylene oxide.
