본 고안은 펌프와 연관시킨 흡수관 하단 입수구에 후드밸브를 설치하여 펌프정지시 흡수관 하단을 밀폐시켜 펌프내의 충수상태를 유지시켜주어 펌프의 제가동시 펌프의 흡수기능을 보장해주는 원추형 후드 밸브에 관한 것이다.The present invention provides a conical hood valve that installs a hood valve at the lower inlet of the absorption tube associated with the pump to seal the bottom of the absorption tube when the pump is stopped to maintain the filling state in the pump to ensure the absorption function of the pump when the pump starts up. will be.

종래의 후드밸브들 즉 리프드 디스크식 후드 밸브나 버터프라식 후드밸브들은 모두가 유슈방향과 추직된 평면씨이트로 구성되어 있어 이 평면에 모래나 흙과 같은 이물질이 누적되면 밀폐가 정확히 이루어지지 않아 흡수관내의 물이 지하수나 지하저수조로 빠저나가게 되므로 펌프의 흡수기능을 상실하는 문제점이 있엇다.Conventional hood valves, ie, lift disc type hood valves and butterfly type hood valves, are all composed of a yushu direction and a flat flat surface, so that when foreign substances such as sand or soil accumulate on this plane, the sealing is not made correctly. Since water in the absorption pipe is drained into the groundwater or the underground reservoir, there is a problem that the absorption function of the pump is lost.

본 고안은 이와같은 문제점을 해소하기 위하여, 밸브동체와 입수여과기 사이에 벤튜리형 밸브씨이트를 형성하여 이에 원추형 개폐변이 개폐되게 설치한 본 고안을 급수펌프의 흡수관 하단에 설치하면 물속에 모래나 흙이 함유되어 있어도 벤튜리형 밸브씨이를 원추형 개폐변이 개폐케 하였기 때문에 밸브씨이트에 누적되는 일이 없으므로 장기간 밀폐상태가 유지되어 펌프정지시 흡수관내의 물이 빠저나가는 일이 거의 없어 픔프의 재가동이 원활하게 이루어지게 한 것이다.In order to solve such a problem, the present invention, which forms a venturi valve seat between the valve body and the inlet filter and opens and closes the conical opening and closing valve, is installed at the bottom of the absorption pipe of the feed water pump. Even if soil is contained, the venturi valve valve opens and closes to the valve seat, so it does not accumulate in the valve seat. Therefore, the state of sealing is maintained for a long time, so that the water in the absorption pipe is almost never drained when the pump is stopped. It is made smoothly.

이상과 같은 된 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings of the present invention as described above are as follows.

동체(1)의 내부에 형성한 지지간(2) 중앙에 뚫은 원통공(3)에 고무재질의 오링(4)이 끼워진 원추형 개폐변(5)의 변봉(6)을 상하작동되게 끼우고 원추형 개폐변(5)의 하부에는 45도 내지 60도 정도로 확산된 베튜리형 씨이트(7)를 동체(1)에 끼워 설치한 다음 그 하부에 공지한 반구형 여과기(8) 대고 동체(1)와 보울트(9)로 고정하여서된 것이다.In the cylindrical hole 3 formed in the center of the support body 2 formed in the body 1, the rod 6 of the conical opening and closing edge 5, in which the rubber O-ring 4 is fitted, is inserted up and down to operate the cone. In the lower part of the opening / closing side 5, the Vary-shaped sheet 7 diffused about 45 to 60 degrees is inserted into the body 1, and then the well-known hemispherical filter 8 is placed in the lower part of the body 1 and the bolt. It is fixed by (9).

이상과 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as described above are as follows.

동체(1) 내부에 형성한 지지간(2)의 중앙에 뚫은 원통공(3)에 원추형 개폐변(5)의 변봉(6)을 상하작동되게 끼우고 그 하부에 45도 내지 60도 정도로 확산시킨 벤튜리형 씨이트(7)를 동체(1)에 끼워 설치하고 그 하부에 반구형여과기(8)를 대고 동체(1)와 보울트(9)로 고정시킨 본 고안을 급수펌프의 흡수관 하단에 설치하게 되면 급수시에는 제2도에서와 같이 원추형 개폐변(5)이 상승하여 열리게 되므로 급수가이 이루어 지고 급수펌프의 정지시는 제1도에서와 같이 원추형 개폐변(5)이 하강하여 원추형 개폐변(5)의 외주에 끼워진 고무재질의 오링(4)이 벤튜리형 밸브 씨이트(7)에 밀착되어 밀폐시키므로서 누수되는 일이 거의 없다.Insert the rod 6 of the conical opening and closing edge 5 into the cylindrical hole 3 formed in the center of the support section 2 formed in the body 1 so as to be operated up and down and spread it to the lower portion of about 45 to 60 degrees. Installed the venturi type sheet 7 into the fuselage 1, and placed the hemispherical filter 8 on the lower part of the venturi type sheet 7 and fixed it with the fuselage 1 and the bolt 9 at the bottom of the absorption pipe of the feed water pump. When water is supplied, the conical open / close valve 5 rises and opens as shown in FIG. 2, and thus the water supply is made. When the water pump is stopped, the conical open / close valve 5 descends as shown in FIG. O-ring 4 made of rubber material fitted to the outer periphery of (5) is tightly sealed to the venturi-type valve seat 7 so that water is hardly leaked.

여기에서 벤튜리형 밸브씨이트(7)의 확산각도를 45도 내지 60도로 형성할 경우가 가장 이상적으로 밀폐효과를 얻을 수 있다.Here, in the case where the diffusion angle of the venturi-type valve seat 7 is formed at 45 degrees to 60 degrees, the sealing effect is most ideally obtained.

밸브씨이트(7)를 벤튜리형으로 구성하였기 때문에 사용중에 물속에 함유되어 있는 모래나 흙이 누적되는 일이 없으므로 장기간 밀폐상태가 유지되어 펌프정지시 흡수관내의 물이 빠져나가는 일이 거의 없으므로 펌프의 재가동이 원활이 이루어지게 하는 이점이 있는 것이다.Since the valve seat 7 is formed in a venturi type, the sand and soil contained in the water do not accumulate during use, so the sealed state is maintained for a long time, so that the water in the absorption pipe hardly escapes when the pump is stopped. There is an advantage that can be restarted smoothly.
