본 고안은 통상적인 자흡식 와류펌프에서 펌프의 가동정지시 마중물탱크 내부의 마중물이 역류됨을 방지하여 펌프내부의 진공부와 압렵부를 분리하여 주므로서 펌프가동시에 물이 즉시 양수되도록 하는 역할을 하는 프트밸브(FOOT VALVE)에 관한 것이다.The present invention prevents the backflow of the inside of the cargo tank in the normal self-priming vortex pump to stop the backflow of the pump to separate the vacuum part and the pressure part inside the pump, so that the pump serves to immediately pump water when the pump is running. FOOT VALVE.

통상적으로 자흡식 와류펌프에서 채택 사용하고 있는 프트밸브의 설치구조를 보면 첨부도면 제5도에서 보는 바와 같이, 흡입관(5) 상부에 링형태의 밸브시이트 (1)를 설치하고 밸브시이트(1)의 가이드면(1a)에 접하여 승강안내되는 다수의 분할가이드편(2a)을 가진 밸브본체(2)를 탄발스프링(3)에 의해 탄발 지지되도록 조립 설치하여서 마중물탱크(4) 내부에 차있는 마중물이 펌프의 가동정지시 흡입관(5)을 통해 역류되지 못하도록 하는 것이었다.As shown in FIG. 5 of the accompanying drawings, a ring-shaped valve seat 1 is installed on the suction pipe 5 and the valve seat 1 is installed. The pick-up body which is filled inside the pick-up tank 4 by assembling and installing the valve body 2 having a plurality of split guide pieces 2a guided up and down in contact with the guide surface 1a of the tank by the ball spring 3. The pump was prevented from flowing back through the suction pipe 5 when the pump was stopped.

그러나 상기한 바와 같은 자흡식 와류펌프용 프트밸브 구조에서 수반되는 문제점으로는 도면 제3도에서와 같이, 밸브시이트(1)의 상단접촉면(1′)이 평면으로 가공되는 것이어서 밸브본체(2)에 끼워져 있는 패킹(a)과의 접촉면적이 면(面)접촉으로 넓어지게 되는 것인바, 긴밀한 접촉을 위한 시이트(1)의 넓은 상단접촉면(1′)을 정밀가공해야 됨에 따른 가공상의 어려움이 있는 것이었다.However, the problems associated with the above-described self-priming vortex pump pump structure, as shown in Figure 3, the upper surface (1 ') of the valve seat 1 is processed in a plane, so the valve body (2) The contact area with the packing (a) inserted in the surface is to be widened to the surface (bar) contact, the difficulty in processing due to the precision processing of the wide top contact surface (1 ') of the sheet (1) for close contact It was.

또한, 밸브시이트(1)의 상단접촉면(1′)과 가이드면(1a) 사이가 직각을 이루게 되어 있어서 밸브시이트(1)의 가이드면(1a)을 타고 승강케되는 밸브본체(2)가 펌프의 가동정지시 탄발스프링(3)의 탄발복귀격을 받아 하강될때 정확한 수직상태로 하강되지 않고 밸브시이트(1)의 가이드면(1a)과 밸브본체(2)의 가이드편(2a)간에 허용공차 범위안에서 약간 기울어진 상태로 하강될 경우 제4도에서 보는 바와 같이, 가이드편(2a)간에 허용공차 범위안에서 약간 기울어진 상태로 하강될 경우 제4도에서 보는 바와 같이, 가이드편(2a)의 상부턱이 밸브시이트(1)의 상단 직각모서리 부분에 걸리게 되면 패킹(a)과 밸브시이트(1)와의 접촉상태가 불량하게 되어 기밀성을 상실하게 되므로 마중물탱크(4) 내부의 마중물이 흡입관(5)으로 역류되어 빠져나오게 됨에 따라 프트밸브의 기능을 다하지 못하게 되며, 이렇게 되면 펌프를 다시 가동시키고자 할때 마중물탱크(4)내에 마중물을 먼저 채워준 뒤에 가동시켜야만 되는 번거로움을 수반하는 것이었다. 또한 마중물탱크(4)가 비어 있는 것을 모르고 펌프를 그대로 가동시키게 되면 펌프 케이싱 내부의 임펠러 부위가 건조한 상태에서 공회전을 하게 됨에 따라 회전마찰력이 커지게 되어 임팰러 부위의 파손을 초래하게 되는 것이었다.In addition, the valve body 2, which is formed at right angles between the upper contact surface 1 'of the valve seat 1 and the guide surface 1a, is driven up and down by the guide surface 1a of the valve seat 1 to pump. Allowance between the guide face 1a of the valve seat 1 and the guide piece 2a of the valve body 2 without descending to the correct vertical state when descending due to the bullet return return of the ball spring 3 during operation stop. As shown in FIG. 4 when lowered slightly in the range, as shown in FIG. 4, when lowered slightly inclined within the tolerance range between the guide pieces 2a, as shown in FIG. When the upper jaw is caught by the upper right corner of the valve seat 1, the contact state between the packing a and the valve seat 1 becomes poor and airtightness is lost. As it flows back out of the Able to fulfill the functions, and, thereby, when so when operating the pump and back to the first party chaewojun the priming in the priming tank (4) involves the inconvenience that the movable sikyeoyaman behind. In addition, when the pump is operated without being aware that the intermediate tank 4 is empty, the impeller portion inside the pump casing is idling in a dry state, and the frictional force increases, causing damage to the impeller portion.

본 고안은 이와 같은 종래의 프트밸브가 지니고 있는 문제점을 해결하여 밸브시이트(1)내에서 승강 작동되는 밸브본체(2)의 작동이 항상 정확하게 동작되도록 하고 밸브시이트(1)의 상단접촉면(1′)과 패킹(a)간의 긴밀한 밀접력 유지를 위한 밸브시이트(1)의 상단접촉면(1′)가공을 용이하게 할 수 있게 함에 그 목적이 있는 것이다.The present invention solves such a problem of the conventional lift valve so that the operation of the valve body 2 which is lifted and operated in the valve seat 1 is always operated correctly, and the upper contact surface 1 'of the valve seat 1 is operated. In order to facilitate the processing of the upper contact surface (1 ') of the valve seat (1) for maintaining a close close force between the and the packing (a).

본 고안의 내용을 첨부 도면에 의거 상세히 설명하면 다음과 같다. 즉, 패킹 (a)이 끼워진 밸브본체(2)에 요입면(2a′)를 형성하면서 일체로 햐향 돌설시킨 가이드편(2a)들이 링형태로 된 밸브시이트(1)의 가이드면(1a)을 타고 접동 승강되면서 밸브시이트(1)의 상단접촉면(1′)에 패킹(a)이 밀접되게 하여 마중물의 역류를 방지토록 구성한 자흡식 와류펌프의 프트밸브에 있어서, 밸브시이트(1)의 상단접촉면을 곡면(1″)으로 형성하여, 동곡면(1″)과 연이어지는 가이드면(1a)의 상단 내면부에 요입면(1a′)을 형성하여서 구성됨을 특징으로 한 자흡식 와류펌프의 프트밸브인 것이다.The content of the present invention will be described in detail with reference to the accompanying drawings. That is, the guide surface 2a of the valve sheet 1 in which the guide piece 2a which protrudes integrally while making the concave indentation surface 2a 'is formed in the valve body 2 in which the packing (a) was fitted, is ring-shaped. In the lift valve of the self-priming vortex pump configured to close the packing (a) to the upper contact surface (1 ') of the valve seat (1) while preventing ride flow, the upper contact surface of the valve seat (1) To form a curved surface 1 ″, and a concave inlet surface 1a ′ is formed at the upper inner surface of the guide surface 1a that is connected to the curved surface 1 ″. It is

첨부 도면중 미설명부호 4a는 마중물 주입구마개, 6은 토출관, 7은 펌프케이싱을 나타내는 것이다.In the accompanying drawings, reference numeral 4a denotes a stopper injection hole plug, 6 a discharge tube, and 7 a pump casing.

본 고안은 상술한 바와 같이, 밸브시이트(1)의 가이드면(1a) 상단내면부에 요입면(1a′)을 형성하여 주므로서, 펌프의 가동정지로 인하여 흡입관(5)을 통해 올라오던 물의 흡입이 중단됨에 따라 밸브본체(2)를 상승시켜주고 있던 유체압력이 약화되면서 상대적으로 탄발스프링(3)의 복귀격을 받게 되는 밸브본체(2)가 하강되어질때 밸브본체(2)가 정확한 수직작동을 하지 않고 약간 기울어진 상태로 하강되어진다 하더라도 밸브시이트(1)에 형성시켜준 상단요입면(1a′)과 밸브본체(2)에 형성되어 있는 기존의 요입면(2a′)에 의해 상호 걸림요소가 제거되었으므로 밸브본체(2)는 수직으로의 정확한 승강 안내작동이 가능하게 되어 밸브시이트(1)의 상단면과 패킹(a)이 상호 긴밀하게 밀접케 되는 것이어서 마중물의 역류방지를 위한 프트밸브의 기능을 보다 완벽하게 수행하게 되는 것이다. 또한 밸브본체(2)의 패킹(a)과 밀접되어지는 밸브시이트(1)는 그 상단접촉면이 곡면(1″)으로 형성되어 있어 패킹(a)과의 접촉면적이 좁은 선(線)접촉을 이루게 됨에 따라 그 기밀상태가 종래의 면(面)접촉일때보다 확실하게 되는 동시에 곡면으로 된 상단접촉면의 가공작업도 보다 수월하게 되는 매우 유용한 효과를 제공하여 주는 것이다.The present invention, as described above, by forming a concave inlet surface (1a ') in the upper inner surface of the upper surface of the guide surface (1a) of the valve seat (1), due to the operation of the pump of the water that has risen through the suction pipe (5) As the suction stops, the fluid pressure that raises the valve body 2 decreases, and when the valve body 2, which receives the return rate of the carbon spring 3, is lowered, the valve body 2 is precisely vertical. Although lowered in an inclined state without operation, the upper recessed surface 1a 'formed on the valve seat 1 and the existing recessed surface 2a' formed on the valve body 2 are mutually Since the locking element has been removed, the valve body 2 is capable of precisely moving up and down vertically, so that the upper surface of the valve seat 1 and the packing a closely close to each other. More fully functional valve Will be done. In addition, the valve seat 1, which is in close contact with the packing a of the valve body 2, is formed with a curved surface 1 ″ at its upper end surface, thereby providing a line contact with a narrow contact area with the packing a. As a result, the airtight state becomes more reliable than that of the conventional surface contact, and at the same time, it provides a very useful effect that makes the upper surface of the curved contact surface easier to work with.
