Abstract
The present invention relates to a permanent magnetic turning needle type valve for water supply pipeline. It is composed of a fully sealed valve body, a valve core having a static plate and a movable plate, a valve rod and an external magnetic ring. Under the action of magnetic force, the turning needle type valve rod turns along with the rotation of external magnetic ring, thereby drives the movable plate to realize the open and close of pipeline. The invented valve body is fully sealed and leakless, at the same time, it possesses the characteristics of no corrosion, no ageing, no loosening of parts and very little wear.
Description
The present invention relates to a kind of permanent magnet rotating needle type valve, be used for water supply line.
It is extremely urgent to economize on water, and prevents that the pipeline evaporating, emitting, dripping or leaking of liquid or gas from being important water saving measures.Yet employed valve is stop valve or ball valve in the pipeline now, all has a hole that communicates with the external world on its valve body, and the valve rod of the inside stretches out outside the valve body thus, seals with seal ring therebetween.But owing to exist problems such as fret wear, aging, corrosion and part be loosening, often produce and leak outside or leak in producing, cause water resources to be lost in vain because of spool is not closed completely.
Purpose of the present invention is to provide a kind of permanent magnet rotating needle type valve, and is existing with the existing the problems referred to above of valve to solve, and can stop the pipeline evaporating, emitting, dripping or leaking of liquid or gas effectively.
The object of the present invention is achieved like this: adopt a kind of permanent magnet rotating needle type valve, it by valve body and be positioned at its inner spool, valve rod and be enclosed within its outside outer magnetic ring formed.It is characterized in that: valve body is full closeding state to external world except that entery and delivery port.Spool is served as reasons and is fixed on down crossing the stator on the mouth of a river and floating the planar seal that pendulum moving plate is thereon formed of valve body.Valve rod adopts the ferromagnetic material manufacturing, and the head of the last body of rod is the uniform petal-shaped of petal, and the following body of rod is provided with boss, inserts in the groove on the moving plate, and last body of rod top bit is located in the axle center, is provided with a sharp garden awl projection.The outer magnetic ring kink is on upper valve body, and be equipped with along circumferential uniform permanent-magnet block its inside, and the quantity of permanent-magnet block is identical with the petal quantity of last body of rod head, and forms mutual one to one magnetic attraction relation between the two.The position-limit mechanism of valve opening and closing is made of boss that is located at body of rod top and the garden arc groove that is located on the upper valve body top cover internal surface with matching.Under magnetic force, the valve rod that is rotating needle type will rotate with the rotation of outer magnetic ring like this, rotate thereby drive moving plate, realize closing of valve.For solid particle in the anti-sealing enters in the gap of body of rod head and upper valve body, on the last body of rod,, overlap a baffle plate that is fixed on the upper valve body more all around against the lower surface of packing ring against packing ring of lower surface kink of petal-shaped head.Be the state of being slidingly matched between packing ring, baffle plate and the last body of rod.In order to prevent that solid particle from entering between moving, the stator of spool, having a center hole on the body of rod down, a pressure spring is installed in the inside, makes and produces a pressure between stator and moving plate all the time.In order to reduce cost, outer magnetic ring can be loaded onto and take off conveniently, and a plurality of valves can a shared outer magnetic ring.Valve can be taked multiple Placement: the first adopts the quick-acting pipe spare of patent application 01264677.6 that valve is connected with pipe, and for this reason, water inlet place of following valve body and water outlet place are the straight collimator structure, and its external diameter is identical with the same specification tube outer diameter.Its two be the structure of down valve body water-in and water-out place all the quick-acting pipe spare with patent application 01264677.6 is identical, just can directly valve and pipe be linked together without pipe fitting like this.Three to be the structures at down valve inleting water place identical with bonding pipe fitting among the patent application 00130741.X for it, and the structure of water outlet place is identical with the quick-acting pipe spare of patent application 01264677.6, also can directly valve be connected with pipe without pipe fitting like this.
The present invention leaks outside owing to adopting totally-enclosed valve body, can not producing.Because stator is fixed on down valve body and crosses on the mouth of a river, and the floating pendulum of moving plate is on stator, hydraulic pressure acts on the moving plate from top to bottom all the time, can produce good sealing all the time between the two, also can not produce interior leakage again.In valve, except that moving plate, valve rod is a unique movable members, it except that top and valve body top cover with needle-like contact with the bottom with boss with moving plate contacts, remaining part does not contact with other part basically, even contact does not have positive pressure yet, because be subjected to balanced attraction force around the valve rod, wearing and tearing are very little.In valve, the material that contacts with fed sheet of a media has only stainless steel and pottery, and they are corrosion-resistant material.In valve, there are not sealing materials such as rubber is arranged, there is not problem of aging.In valve, there is not the Placement that has screw thread, key etc. easily loosening between the part.In sum, the present invention has eliminated and has shortened the valve various factors in working life, can effectively stop the pipeline evaporating, emitting, dripping or leaking of liquid or gas problem that produces owing to valve invalidation.
Concrete structure of the present invention is provided by accompanying drawing.
Accompanying drawing is the sectional drawing of the permanent magnet rotating needle type valve of proposition according to the present invention.
