Summary of the invention
The utility model has solved the difficult or existing high pressure triple pipe air deflector of the rotatory sealing of water under high pressure of the high pressure triple pipe that prior art exists middle pipe is made as logical slurry pipe or outer tube is made as logical slurry pipe, close conjuncted the current of cement paste that hinder owing to being provided with between interior Guan Yuzhong pipe or middle pipe and the outer tube, cause the mud plugging, the problems such as application life of high pressure triple pipe air deflector have been shortened, provide a kind of reasonable in design, water under high pressure rotatory sealing is better, the high pressure triple pipe air deflector that application life is long.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise the into interior pipe of slurry, the outer outer tube that leads to the middle pipe of water under high pressure and be placed in the outer ventilation of middle pipe of pipe in being placed in, be provided with bearing between described outer tube and housing, Guan Yuzhong pipe upper end is provided with end plate in described, described end plate is provided with at least one axially extending bore that connects with middle pipe, and its lower end is provided with slurry-feeding hole that endoporus with interior pipe is complementary and that pass from the side of end plate; Described end plate top is provided with water inlet pipe, and the internal diameter of described water inlet pipe is less than or equal to the axis of being located at the axially extending bore that connects with middle pipe on the described end plate and the distance of end plate axis; Be provided with the end cap that upper and lower side joins with water inlet pipe and end plate respectively between described water inlet pipe and the end plate, described end cap is provided with the last through hole and the lower through-hole of mutual perforation, the described internal diameter of going up through hole and water inlet pipe is complementary, and described lower through-hole communicates with the axially extending bore of end plate.Wherein, the internal orifice dimension of water inlet pipe than in pipe be that the internal diameter of water pipe is little, when high pressure triple pipe rotated, the linear velocity of the middle pipe mesohigh of the linear velocity water of water inlet pipe mesohigh water was little under the identical rotating speed, made the problem of rotatory sealing difficulty of high pressure triple pipe mesohigh water obtain effective solution; Interior pipe is made as the slurry pipe, makes mud unimpeded in body, improved application life of the present utility model.
As preferably, the axially extending bore on the described end plate is one or more arc-shaped through-holes; Axially extending bore on the described end plate is several circular holes.Wherein, the hole that can adopt other different shape of the axially extending bore on the end plate that connects with middle pipe.
As preferably, between bearing and bearing, be provided with air inlet on the described outer tube.Wherein, air inlet is provided with between two bearings, can effectively utilizes the space between two bearings, shortened the length of high pressure triple pipe air deflector to a certain extent, make the utility model seem more compact.
As preferably, the inner hole section of described water inlet pipe long-pending with described end plate on the axially extending bore total sectional area suitable.Wherein the inner hole section of water inlet pipe long-pending with end plate on the axially extending bore total sectional area quite can effectively guarantee the uniformity of discharge in discharge in the water inlet pipe and the middle pipe.
Characteristics such as therefore, the utlity model has reasonable in designly, water under high pressure rotatory sealing is better, and application life is long.Wherein, the internal orifice dimension of water inlet pipe than in pipe be that the internal diameter of water pipe is little, when high pressure triple pipe rotated, the linear velocity of the middle pipe mesohigh of the linear velocity water of water inlet pipe mesohigh water was little under the identical rotating speed, made the problem of rotatory sealing difficulty of high pressure triple pipe mesohigh water obtain effective solution; Interior pipe is made as the slurry pipe, has reduced the granularity requirements of cement paste, make mud unimpeded in body, improved application life of the present utility model.Wherein, the hole that can adopt other different shape of the axially extending bore on the end plate that connects with middle pipe.Wherein, air inlet is provided with between two bearings, can effectively utilizes the space between two bearings, shortened the length of high pressure triple pipe air deflector to a certain extent, make the utility model seem more compact.Wherein the inner hole section of water inlet pipe long-pending with end plate on the axially extending bore total sectional area quite can effectively guarantee the uniformity of discharge in discharge in the water inlet pipe and the middle pipe.
