Abstract
The utility model relates to a durable water nozzle, comprising a fully-closed valve body (1), a ceramic stator plate (3), a ceramic rotor plate (4) and a valve stem (5) that are provided inside the valve body, and an external magnetic ring (2) that is flexibly socketed on the upper part of the valve body (1), wherein both the valve body (1) and the valve stem (5) are made of stainless steel. The utility model absolutely does not leak internally or externally, and does not lead to a dripping channel caused by wearing, corrosion, aging and loosened structure etc. The utility model is most distinctively characterized by secured and reliable performance and long service life.
Description
The utility model relates to a kind of Durable water injection well choke, plays the shutter effect in pipeline.
Now employed valve and water nozzle in the pipeline are because wearing and tearing, burn into is aging or because of connection loosing, open and close reasons such as malfunctioning, often produces the evaporating, emitting, dripping or leaking of liquid or gas problem of fluid, causes very big loss.
The purpose of this utility model is to provide a kind of Durable water injection well choke, to solve evaporating, emitting, dripping or leaking of liquid or gas problem in the pipeline.
The purpose of this utility model be achieved in that one by totally enclosed valve body be arranged in the water nozzle that its inner spool and kink are formed at the outer magnetic ring of valve body exterior upper portion, spool is made up of ceramic stator, ceramic moving plate and valve rod from bottom to top successively.It is characterized in that: ceramic stator is by inlaying or being adhesively fixed on the mouth of a river excessively of valve body.The floating pendulum of pottery moving plate is on ceramic stator.The valve rod lower end is provided with boss, inserts in the groove of being opened on the ceramic moving plate.Be positioned at the place, axle center at the valve rod top, be provided with a boss, go deep in the groove of valve body top cover.Between valve rod and valve body except that the boss at this top with groove directly contacts, remaining part does not produce direct contact.Valve body adopts the Austenitic Stainless Steel manufacturing, and valve rod has only a part and only adopts martensite or Ferritic Stainless Steel manufacturing.
The utility model leaks outside owing to adopting totally-enclosed valve body, can not producing.Because ceramic stator is fixed on valve body and crosses on the mouth of a river, the floating pendulum of ceramic moving plate can produce good sealing, so can not produce interior leakage under hydraulic pressure on ceramic stator again.Except that ceramic moving plate, valve rod is a unique moving parts in valve body, and it is except that the boss of top, and remaining part does not all directly contact with valve body, so wearing and tearing seldom.Because whole valve body and spool only adopt stainless steel and two kinds of made of pottery, can not produce again because of corrosion or the aging Problem of Failure that makes it.In addition, in this structure, do not have attachment portions such as screw thread, key are arranged, can not produce because of connection loosing yet and make the malfunctioning problem that opens and closes.Be an embodiment of the present utility model below, and the utility model is described in further detail with this embodiment in conjunction with the accompanying drawings.
Accompanying drawing is a kind of longitudinal section tectonic maps of Durable water injection well choke.
Among the figure: 1-valve body 2-outer magnetic ring 3-ceramic stator 4-pottery moving plate 5-valve rod
Adopt technological wax pattern to cast out 304 stainless valve bodies (1) and the stainless valve rod of 2Cr13 (5) respectively, when casting valve rod (1), ceramic stator (3) is embedded in it simultaneously and crosses on the mouth of a river.Pack in the valve body (1) behind ceramic moving plate (4) and the valve rod (5), 304 stainless valve gaps are covered and welded together with valve body (1).The outer magnetic ring (2) of permanent magnet is housed at valve body (1) exterior upper portion kink.
Claims (2)
1. Durable water injection well choke, by totally enclosed valve body (1) be positioned at its inner spool and kink is formed at the outer magnetic ring (2) of valve body (1) exterior upper portion, spool is made up of ceramic stator (3), ceramic moving plate (4) and valve rod (5) from bottom to top successively, it is characterized in that: ceramic stator (3) is by inlaying or being adhesively fixed on the mouth of a river excessively of valve body (1), and the floating pendulum of ceramic moving plate (4) is on ceramic stator (3); Valve rod (5) lower end is provided with boss, inserts in the groove of being opened on the ceramic moving plate (4), is positioned at the place, axle center at valve rod (5) top, is provided with a boss, gos deep in the groove of valve body (1) top cover; Between valve rod (5) and valve body (1) except that the boss at this top with groove directly contacts, remaining part does not produce direct contact.
2. a kind of Durable water injection well choke according to claim 1 is characterized in that: valve body (1) adopts the Austenitic Stainless Steel manufacturing, and valve rod (5) has only a part and only adopts martensite or Ferritic Stainless Steel manufacturing.
