Abstract
The utility model discloses a butterfly valve equipped with an axial positioning structure. The connection part of a valve rod and an inner hole surface of a valve body is provided with a clamping groove, in which a clamping ring is arranged. The intersection part of the inner hole surface of the valve body and a vertical surface of the valve rod is provided with a limiting block. The butterfly valve equipped with the axial positioning structure has following beneficial effects: the clamping ring, the clamping groove and the limiting block are arranged so that no matter which position or angle the butterfly valve is disposed at, the movement amount is not easily produced by a valve plate in the direction of the valve rod; and therefore the sealing effect of the valve plate is not affected.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of butterfly valve with axial positioning structure.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve is also divided into cast iron valve, cast steel valve, stainless valve etc. according to material.
Butterfly valve is again Flap valve, is a kind of modulating valve simple in structure, and the switch that also can be used for low pressure pipeline medium is simultaneously controlled.Butterfly valve refers to that closure member (flap or butterfly plate) is disk, rotates to reach a kind of valve of open and close around valve shaft, and on pipeline, main rising cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.
Butterfly valve comprises valve rod, valve body, valve plate, valve seat, in prior art, macrotype butterfly valve usually needs to be arranged on some special occasion, the valve rod of macrotype butterfly valve cannot vertically be placed, thereby cause valve plate in valve rod direction, easily to produce less activity, but affected the effect of valve plate sealing.
Summary of the invention
The purpose of this utility model is to provide a kind of telescopic butterfly valve with elastic structure, the problems referred to above that exist to solve prior art.
In order to complete the utility model object, the utility model provides a kind of butterfly valve with axial positioning structure, and described valve rod and described valve body inner bore face joint are provided with draw-in groove, in described draw-in groove, are provided with snap ring.
Wherein, described valve body inner bore face and described valve rod vertical surface intersection are provided with radially limiting stopper.
The utility model is by arranging snap ring, draw-in groove and limiting stopper, no matter makes in what orientation, what angle places butterfly valve, can not cause valve plate in valve rod direction, easily to produce activity, thereby can not affect the effect of valve plate sealing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, the upper draw-in groove of 1-, 2-is limiting stopper radially, 3-valve rod, 4-valve body, 5-valve body inner bore face, 6-lower bayonet slot.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the purpose of this utility model is to provide a kind of telescopic butterfly valve with elastic structure, the problems referred to above that exist to solve prior art.
In order to complete the utility model object, the utility model provides a kind of butterfly valve with axial positioning structure, and described valve rod and described valve body inner bore face joint are provided with draw-in groove, in described draw-in groove, are provided with snap ring.
It should be noted that, described valve rod and described valve body inner bore mask have two tie points, these two tie points can one or two arrange draw-in groove, in draw-in groove, snap ring can be set, be used for fixedly valve plate, avoid valve plate to produce activity along with the difference of mounting point and setting angle, thereby affect the sealing effect of valve plate.
Wherein, described valve body inner bore face and described valve rod vertical surface intersection are provided with radially limiting stopper.
It should be noted that, the valve plate of described valve generally angle rotatable is 90 degree, when closing for fear of valve plate, surpassed valve seat place, thereby affect the working efficiency that valve is used, at described valve seat, place arranges limiting stopper, for when the valve closing time, time limiting stopper, automatically stop operating, improved the utilization efficiency of valve.
The utility model is by arranging snap ring, draw-in groove and limiting stopper, no matter makes in what orientation, what angle places butterfly valve, can not cause valve plate in valve rod direction, easily to produce activity, thereby can not affect the effect of valve plate sealing.
Above-mentioned is only embodiment of the present utility model, for those of ordinary skill, is not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. with a butterfly valve for axial positioning structure, it is characterized in that, described valve rod and described valve body inner bore face joint are provided with draw-in groove, in described draw-in groove, are provided with snap ring.
2. the butterfly valve with axial positioning structure according to claim 1, is characterized in that, described valve body inner bore face and described valve rod vertical surface intersection are provided with radially limiting stopper.
