Abstract
The utility model discloses one can positive opening formula screw down nonreturn valve, comprise valve body, flap, valve rod, two points of rings and valve clack cover, described flap is arranged on valve body, described valve rod one end is fixed on flap through two points of rings, described two points of rings are compressed on valve rod, two ends are fixed on valve clack cover, and described valve clack cover is connected with flap.Working principle of the present utility model: increase by two points of rings between flap, valve rod, valve clack cover three, by the mounting or dismounting by two points of rings, realize the conversion between stop valve and screw down nonreturn valve.When needs screw down nonreturn valve time, two points of rings are dismantled, meet non-return effect of screw down nonreturn valve; When needs stop valve time, two points of rings are loaded onto, realize positive closing effect of stop valve.While guarantee screw down nonreturn valve effect, the conversion between stop valve can be realized easily, accomplishes interchangeability, enhance Multifunctional stop valve, while meeting operating mode, reduce cost.
Description
Technical field
The utility model relates to screw down nonreturn valve field, and especially one can positive opening formula screw down nonreturn valve.
Background technique
At present, known screw down nonreturn valve adopts flap, valve rod, valve clack cover composition, and this structure is opened the main pressure of flap medium that relies on and promoted flap, slides up and down inside valve clack cover; Cut out main dependence handwheel acts on valve rod and cuts out downwards.But this structure must rely on the pressure of medium just can open when opening, some operating modes need just cannot realize when positive opening.
Model utility content
For the problems referred to above, the utility model aims to provide and a kind ofly can adapt to special working condition requirement, and while meeting cut-off non-return, what realize initiatively opening can positive opening formula screw down nonreturn valve.
For realizing this technical purpose, scheme of the present utility model is:
One can positive opening formula screw down nonreturn valve, comprise valve body, flap, valve rod, two points of rings and valve clack cover, described flap is arranged on valve body, described valve rod one end is fixed on flap through two points of rings, described two points of rings are compressed on valve rod, two ends are fixed on valve clack cover, and described valve clack cover is connected with flap.
As preferably, described two points of rings are arranged between flap and valve rod and valve clack cover three.
Working principle of the present utility model: increase by two points of rings between flap, valve rod, valve clack cover three, by the mounting or dismounting by two points of rings, realize the conversion between stop valve and screw down nonreturn valve.When needs screw down nonreturn valve time, two points of rings are dismantled, meet non-return effect of screw down nonreturn valve; When needs stop valve time, two points of rings are loaded onto, realize positive closing effect of stop valve.While guarantee screw down nonreturn valve effect, the conversion between stop valve can be realized easily, accomplishes interchangeability, enhance Multifunctional stop valve, while meeting operating mode, reduce cost.
Accompanying drawing explanation
Fig. 1 is partial structurtes schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the one of the utility model embodiment can positive opening formula screw down nonreturn valve, comprise valve body 1, flap 2, valve rod 3, two points of rings 4 and valve clack cover 5, described flap 2 is arranged on valve body 1, described valve rod 3 one end is fixed on flap 2 through two points of rings 4, described two points of rings 4 are compressed on valve rod 3, and two ends are fixed on valve clack cover 5, and described valve clack cover 5 is connected with flap 2.
As preferably, described two points of rings 4 are arranged between flap 2 and valve rod 3 and valve clack cover 5 three.
Working principle of the present utility model: increase by two points of rings 4 between flap 2, valve rod 3, valve clack cover 5 three, by the mounting or dismounting by two points of rings 4, realize the conversion between stop valve and screw down nonreturn valve.When needs screw down nonreturn valve time, two points of rings 4 are dismantled, meet non-return effect of screw down nonreturn valve; When needs stop valve time, two points of rings 4 are loaded onto, realize positive closing effect of stop valve.While guarantee screw down nonreturn valve effect, the conversion between stop valve can be realized easily, accomplishes interchangeability, enhance Multifunctional stop valve, while meeting operating mode, reduce cost.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
Claims (2)
1. one kind can positive opening formula screw down nonreturn valve, comprise valve body, flap, valve rod, two points of rings and valve clack cover, described flap is arranged on valve body, it is characterized in that: described valve rod one end is fixed on flap through two points of rings, described two points of rings are compressed on valve rod, two ends are fixed on valve clack cover, and described valve clack cover is connected with flap.
2. one according to claim 1 can positive opening formula screw down nonreturn valve, it is characterized in that: described two points of rings are arranged between flap and valve rod and valve clack cover three.
