Valentin Danilovich Belousov was not only a scientist but also an excellent teacher. He has made important contributions in the system of education of Moldova and in training of Moldovan mathematicians. As a member of the Academy of Pedagogical Sciences (Mathematics section), he spent a great scientific and organizational work in the field of mathematics education. About 30 of his students defended their theses and work in many countries. Valentin Belousov and Y.I.Neagu wrote Moldovan-Russian Dictionary of Mathematics, which has long been used by mathematicians Moldova. Together with I.I.Lupu and Y.I.Neagu V.D.Belousov published a book of mathematics in schools of Moldova (1812–1972). For many years, V.D.Belousov was the chairman of the jury of school mathematical Olympiads of Moldova.
Under the direction of Valentin Danilovich 22 mathematics from different republics of the former Soviet Union and from abroad defended their theses, four of them also defended their doctoral dissertations.
In parallel with the scientific and pedagogical activity Valentin Danilovich spent big public work as a deputy Balti City Council (1960–1962), member of the District Committee of the CPM (1967–1973), member of the Supreme Council of Moldova (1975–1980), member of the Presidium of the Society "Knowledge", a member of editorial boards of various domestic and foreign publications, organizing committee member of many international conferences.
Father Daniel Afinogenovich Belousov (1897–1956), was an officer in the army of Tsarist Russia (graduated from military school in Tbilisi). He took part in First World War. In Moldova, he worked at the post office in the city of Balti. Mother of Valentin Danilovich, Elena K. Belousov (Garbu) (1897–1982), also worked at the post office.
Wife – Belousov (Bondareva) Elizabeth Feodorovna (5 May 1925 – 26 November 1991). Philologist, she taught at the State University of Moldova.
Children: Alexander Valentinovich (03.10.1948 – 3 September 1998), PhD in physics, senior research fellow of the Academy of Sciences of Moldova; Tatiana Valentinovna Kravchenko (born 16 February 1952), a doctor neurologist.
Brother: MD Victor Danilovich Belousov (b. 1927) traumatologist orthopedic, the author of the monograph "Road traffic accidents. First aid to victims "(1984) and" Conservative treatment of false joints of long bones "(1990).
For merits in the field of science, education and social activities V.D.Belousov was awarded the Order of the Red Banner of Labor (1961) Honorary Diploma of the Presidium of the Supreme Soviet of the Moldavian Soviet Socialist Republic (1967), he was elected as correspondent member of the Academy of Pedagogical Sciences the USSR (1968).

Despite the strict controls in those years by the government, Valentin Danilovich received permission to research trips abroad and many times traveled abroad:
The lifework of Belousov Valentin Danilovich is continued his numerous disciples and followers in various countries, whose number is constantly increasing. In 1994 at the initiative of the students of V.D.Belousov at the Institute of Mathematics and Computer Science of the ASM was established scientific journal "Quasigroups and Related Systems(http://www.quasigroups.eu/)'", now known all over the world. For twenty years this magazine published many articles both Moldovan and foreign specialists in the theory of quasi-groups and regions close to it. Since 1995, the Institute of Mathematics and Computer Science of the ASM annual birthday Valentin Danilovich (20 February) is carried out advanced algebraic seminar in memory of Valentin Danilovich Belousov. In this workshop, his disciples and followers from Moldova and other countries take stock of the past year, and report on new results in the theory of quasi-groups and related areas.
Thanks to the productive scientific and pedagogical activity of V.D.Belousov in Republic of Moldova was founded on the theory of quasigroups school (Belousov's School on Theory of Quasigroups), consisting of his 22 disciples (http://belousov.scerb.com/) and more than 40 followers continue his work in Moldova and abroad.
