Background technique
Stop valve is a kind of as modulating valve, and structure is low in and high out, and object is to reduce fluid resistance.Existing stop valve structure only has single cutoff function; in its valve cavity, check device is not set; the words of this valve installation before table; if aqueous reflux can cause the damage of equipment; for preventing from flowing backwards, protection equipment repeats again to install a safety check after this valve is installed, and so not only uneconomical but also increased installation labor intensity.Meanwhile, this existing stop valve, its valve is handwheel opening structure, and protective value is poor, can open arbitrarily or close, and this valve is arranged on unwatched local handwheel opening structure and is easy to be closed or open, and is not easy to management, has a strong impact on user's use.In addition, its valve is single sealing configuration, has leakage hidden danger.
Model utility content
The purpose of this utility model is to provide a kind ofly not only has check function, and has the magnetic induction screw down nonreturn valve of magnetic lockable structure.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of magnetic induction screw down nonreturn valve, comprise the valve body that cooperatively interacts and install, valve gap, valve rod, flap, on the upper-end surface of described valve gap, be provided with the valve gap cover of carrying magnetic key, it (is that valve gap cover is arranged on valve gap that rotary type clamping is carried out in valve gap cover lower end and valve gap upper end, valve gap cover under external force simultaneously, valve gap is rotated relatively), valve gap cover offers groove one on lower end surface, magnet steel is installed in groove one from inside to outside successively, straight pin, on valve gap upper-end surface, offer the groove two corresponding with groove one position, groove two is built-in with reducible elastomer, the lower end of straight pin extends down in groove two and props up elastomer, valve rod upper end is fixedly connected with valve gap cover, and valve rod lower end surface offers containing groove, flap comprises the vertical rod that is arranged on lobe body upper-end surface, and vertical rod is slidably nested with in containing groove, on the outer wall of valve rod lower end, be provided with flap cover, between flap cover inner chamber and valve rod lower end external diameter, be threaded, and flap cover be positioned at lobe body upper-end surface, flap cover is outer is equipped with Compress Spring, and Compress Spring is placed between lobe body upper-end surface and valve gap lower end surface.
As the further setting of such scheme, between described valve rod and the upper end of valve gap, be provided with twice O-ring seals, reduced the leakage hidden danger at valve rod place, increased double sealing function, greatly improved the sealability of valve.
Described elastomer is spring.
A kind of magnetic induction screw down nonreturn valve of the utility model; by increasing magnetic induction structure with lock, (be the cooperating structure between magnetic key, magnet steel, straight pin, elastomer; the power wherein producing between magnetic key and magnet steel is repulsive force); greatly improved the protective value of product; overcome the defect that in prior art, handwheel opening structure can be opened arbitrarily or close; and magnetic key highly versatile; greatly facilitate user's use; this valve magnetic texure design is simultaneously unique, and anti-theft feature is strong.Multi-purpose valve function that another this valve is integrated, valve internal increases check device (being the design of flap cover, Compress Spring), this valve can be ended and can non-return, loss and the installation strength of greatly having saved copper material.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of magnetic induction screw down nonreturn valve of the utility model, comprises the valve body 1, valve gap 5, valve rod 13, the flap that cooperatively interact and install.On the upper-end surface of valve gap 5, being provided with the valve gap cover 14 of carrying magnetic key 10, is split-type structural between magnetic key 10 and valve gap cover 14, just as the relation between key and lock.Valve gap overlaps 14 lower ends and valve gap 5 upper ends, and to carry out rotary type clamping (be that valve gap cover 14 is arranged on valve gap 5, valve gap cover 14 under external force simultaneously, valve gap 5 is rotated relatively), valve gap overlaps and on 14 lower end surfaces, offers groove 1, magnet steel 12, straight pin 9 are installed in groove 1 from inside to outside successively, on valve gap 5 upper-end surfaces, offer the groove two 7 corresponding with groove one 11 positions, groove 27 is built-in with reducible elastomer 8, and the lower end of straight pin 9 extends down in groove 27 and props up elastomer 8.Elastomer 8 is preferably spring.Valve rod 13 upper ends are fixedly connected with valve gap cover 14, and valve rod 13 lower end surfaces offer containing groove 6.Flap comprises the vertical rod 3 that is arranged on lobe body 2 upper-end surfaces, and vertical rod 3 is slidably nested with in containing groove 6.Between lobe body 2 and vertical rod 3, be integral structure.On valve rod 13 lower end outer walls, be provided with flap cover 16, flap overlaps between 16 inner chambers and valve rod 13 lower end external diameters and is threaded, and flap overlaps 16 and is positioned at lobe body 2 upper-end surfaces.Flap cover 16 is outer is equipped with Compress Spring 4, and Compress Spring 4 is placed between lobe body 2 upper-end surfaces and valve gap 5 lower end surfaces.
For further improving performance of the present utility model, between valve rod 13 and the upper end of valve gap 5, be provided with twice O-ring seals 15, reduced the leakage hidden danger at valve rod 13 places, increased double sealing function, greatly improved the sealability of valve.
A kind of magnetic induction screw down nonreturn valve of the utility model, while needing unlatching or throttle down, as long as magnetic key 10 is fastened on the upper end outer wall of valve gap cover 14, owing to producing repulsive force between magnetic key 10 and magnet steel 12, magnet steel 12 presses down straight pin 9, until straight pin 9 upper-end surfaces flush (being that straight pin 9 sinks in groove 27 completely) with valve gap 5 upper-end surfaces, release between valve gap cover 14 and valve gap 5 like this, spin magnetization key 10 just can drive valve gap cover 14 to rotate together with valve rod 13.Owing to being to be threaded between flap cover 16 and valve rod 13, in the process of therefore rotating at valve rod 13, the relative valve rod 13 of flap cover 16 meeting moves or moves down on together.
In the utility model, the setting of flap cover 16 is not only played certain leading role to moving up and down of flap, and when valve full cut-off (Compress Spring 4 pressurizeds), flap cover 16 can play downward pressuring action to the lobe body 2 of flap, strengthens seal.When valve wide open, Compress Spring 4 in the raw, produces a downward active force to lobe body 2, makes valve keep nature closed condition, prevents from flowing backwards, and plays non-return effect.
The utlity model has following advantage:
1. in valve body cavity of the present utility model, check device is set, the integrated function of multi-purpose valve, has not only saved the installing space of pipeline and has reduced installation strength, and has more saved the cost of independent installation safety check.
2. the utility model valve rod place increases double-channel sealing structure, greatly reduces the hidden danger of leaking because of valve place, has improved the sealability of valve.
3. pair valve arranges magnetic induction structure, has greatly improved the anti-theft feature of valve, and user friendly management, for user provides the more valve of high-quality.
4. the key of pair this magnetic induction screw down nonreturn valve design specialized, this key is integrated four kinds of function of keys, can open the valve of four sections of different magnetic simultaneously.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
