연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. A mid portion of the body has at least one passage therein leading from a central axial bore to one or more external ports each having a tractor nozzle. The valve outlet connects the axial bore to a cleaning nozzle. A poppet member is received in the central axial bore. In a first position, the poppet member directs fluid flow through the outlet to the cleaning nozzle connected to the outlet. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the tractor nozzles. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.

1. In a piping cleaning apparatus having a high pressure fluid cleaning nozzle attached to a flexible hose for passage through a length of piping to a location requiring cleaning, a flow actuated switching valve connected between the hose and the cleaning nozzle, the switching valve comprising: a valve body having an inlet portion configured to be connected to the hose, a mid portion, an outlet portion configured to be connected to the cleaning nozzle, and a central axial bore therethrough, the mid portion having a plurality of rearwardly directed ports connected by passages to the central axial bore;an elongated poppet member slidably disposed in the central axial bore, the poppet member having a rear portion, a spool portion for selectively opening and closing the passages in the mid portion of the valve body and a closed end portion forming a valve disc for closing the outlet portion of the valve body;a bias member between the poppet member and the valve body biasing the poppet member rearward; anda guide member between the rear portion of the poppet member and the valve body for guiding the poppet member between first and second rotary positions when fluid flow through the valve drops below a predetermined flow rate threshold and then returns above the flow rate threshold. 2. The flow actuated switching valve according to claim 1 wherein the valve disc of the poppet member engages a complementary valve seat in the valve body closing the central axial passage when the poppet member is in the second position. 3. The flow actuated switching valve according to claim 2 wherein when fluid flow is again reduced below the predetermined threshold the valve disc of the poppet member disengages the valve seat and opens the central passage through the outlet portion of the valve body. 4. The flow actuated switching valve according to claim 3 wherein when fluid flow is again increased above the predetermined threshold the guide causes the poppet member to again return to the first position. 5. The flow actuated switching valve according to claim 1 wherein the poppet member has an axial bore extending through the rear portion and the spool portion of the poppet member and the spool portion has at least one or more radial arms extending to the mid portion of the valve body. 6. The flow actuated switching valve according to claim 5 wherein the at least one arm includes a radial passage from the axial bore to the end of the arm. 7. The flow actuated switching valve according to claim 6 further comprising a ball disposed in the radial passage for sealing the passage through the mid portion of the valve body when the poppet member is in the first position. 8. The flow actuated switching valve according to claim 1 wherein the poppet member has a plurality of bypass passages leading from the rear end portion around the axial bore in the spool portion. 9. The flow actuated switching valve according to claim 5 wherein the poppet member has a plurality of bypass passages through the rear end portion around the central axial bore in the spool portion. 10. The flow actuated switching valve according to claim 1 wherein the first position blocks fluid flow through the passage through the mid portion of the valve body and permits fluid flow through the valve body from the inlet end, around the spool portion of the poppet member, and out through the valve body outlet end. 11. The flow actuated switching valve according to claim 1 wherein the second position permits fluid flow through the passage in the mid portion of the valve body. 12. The flow actuated switching valve according to claim 1 wherein the guide member causes the poppet member to rotate when moving between the first and second positions. 13. The flow actuated switching valve according to claim 1 further comprising the poppet member being held at a third position when flow is reduce below the threshold. 14. The flow actuated switching valve according to claim 1 wherein the guide member includes a stationary pin projecting radially inward from an inside surface of the valve body into a complementary groove formed in the rear end portion of the poppet member. 15. The flow actuated switching valve according to claim 14 further comprising at least two spaced stationary pins projecting into complementary grooves formed in the rear end portion of the poppet. 16. The flow actuated switching valve according to claim 4 wherein the guide member includes two or more spaced stationary pins projecting radially inward from an inside surface of the valve body into a complementary groove formed in the rear end portion of the poppet member. 17. The flow actuated switching valve according to claim 16 wherein the guide member includes four equally spaced stationary pins and the complementary groove causes the poppet body to rotate about 45 degrees between each of the first and second positions. 18. In a piping cleaning apparatus having a high pressure fluid cleaning nozzle attached to a flexible hose for passage through a length of piping to a location requiring cleaning, a flow actuated switching valve connected between the hose and the cleaning nozzle, the switching valve comprising: a hollow valve body having an inlet end, an outlet end, a mid portion, and a central axial bore through the inlet end, the mid portion, and the outlet end, the mid portion having at least one passage therein leading from the central axial bore through the valve body to at least one external port;a poppet member received in the central axial bore, the poppet member having an open tubular rear end portion, a spool portion and a closed end valve disc portion, the valve disc portion selectively closing the central axial bore through the outlet end of the valve body, the poppet member having an axial bore extending through the rear portion and the spool portion of the poppet member, the spool portion having at least one or more radial arms extending to the mid portion of the valve body;a biasing member between the valve body and the poppet member biasing the poppet member toward the inlet end of the valve body; anda guide member between the rear end portion of the poppet member and the valve body for guiding the poppet member between first and second rotary positions when fluid flow through the valve drops below a predetermined flow rate threshold and then returns above the flow rate threshold. 19. The flow actuated valve according to claim 18 wherein the valve disc portion of the poppet member engages a complementary valve seat in the valve body closing the central axial passage when the poppet member is in the second position. 20. The flow actuated valve according to claim 19 wherein when fluid flow is again reduced below the predetermined threshold the valve disc portion of the poppet member disengages the valve seat and opens the central passage through the outlet end of the valve body.
