Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As Figure 1-3, the fuel gas plug valve of this invention, including valve body 1, spool 2 and valve rod 3, the end of valve body 1 is fixed with valve gap 5, and spool 2 is located in valve body 1, one end of valve rod 3 is connected through valve gap 5 with the end of spool 2, and is coaxially disposed can rotate by band movable valve plug 2 with spool 2.Spring 4 is also included in valve body 1, this spring 4 is sheathed on outside the end of spool 2 and one end of valve rod 3, and one end of this spring 4 is butted on spool 2, one end is butted on valve rod 3, the one end making this valve rod 3 has the trend being connected with spool 2 disengaging all the time away from the end of described spool 2, namely makes valve rod 3 have the upper trend moved all the time relative to spool 2.
When being typically in fuel gas plug valve use, valve rod 3 needs first to move axially a segment distance towards spool 2 and is then rotated further by realizing igniting, namely valve rod 3 first to be pressed relative to spool 2 and rotate and could light a fire, then valve rod 3 resets upwards under the effect of spring 4, it is rotated further by valve rod 3 afterwards and can also rotate the size of regulating gas with movable valve plug 2, that is valve rod 3 is when band movable valve plug 2 rotates, and has compression spring 4 and does not compress spring 4 two states.The outer sheath of this valve rod 3 and/or spool 2 is provided with damping mechanism 6, this damping mechanism 6 makes valve rod 3 and spool 2 produce frictional damping sense in rotary course, no matter it is which kind of state compression spring 4 is in, namely valve rod 3 be no matter press relative to spool 2 or away from, this damping mechanism 6 can produce frictional damping sense.
As Figure 1-3, this damping mechanism 6 is positioned at the outside of valve gap 5, including the first friction member 61 and the second friction member 62 being disposed adjacent being placed on described valve rod 3, on two surfaces that this first friction member 61 is relative with the second friction member 62, one of them surface is provided with circumferentially distributed profile of tooth concavo-convex 63, another surface is provided with the projection 64 highlighted towards this profile of tooth concavo-convex 63, this first friction member 61 and the second friction member 62 remain the trend being close to, and then when the first friction member 61 and the second friction member 62 are relatively rotated, profile of tooth concavo-convex 63 and projection 64 cooperate and then produce damping sense.This profile of tooth concavo-convex and projection big low height and interval etc. can need adjusted design according to feel.And this projection 64 is at least one, it is also possible to be provided with along the first friction member 61 circumferentially distributed multiple, as it is shown on figure 3, this projection 64 is symmetrical two.
Described first friction member 61 is fixed on the outside of described valve gap 5, this first friction member 61 has projection 64, having profile of tooth concavo-convex 63 on this second friction member 62, this first friction member 61 and the second friction member 62 are all socketed on described valve rod 3, it is possible to move axially relative to valve rod 3.And this first friction member 61 is fixed by socket on the step surface 51 outside valve gap 5, first friction member 61 is fixed with valve gap 5, this second friction member 62 is placed on valve rod 3 and circumferentially positioned relative to valve rod 3, and namely this valve rod 3 and the second friction member 62 can rotating Vortexes.Preferably, this second friction member 62, the first friction member 61 is annular element.The internal diameter of the second friction member 62 is identical with the external diameter of this valve rod 3, for irregular annular, is not namely circular, and therefore, this valve rod 3 can drive the second friction member 62 to circumferentially rotate in the same direction.Therefore when valve rod 3 rotates, it is possible to drive the second friction member 62 to rotate relative to the first friction member 61, and then profile of tooth concavo-convex 63 is made to produce the feel of damping friction with projection 64 interaction.And so that the first friction member 61 and the second friction member 62 are close to all the time, the valve rod 3 in the outside of this second friction member 62 is arranged with back-moving spring 65, one end of this back-moving spring 65 is butted on the second friction member 62 other end and is butted on valve rod 3 radially on spacer 67 outwardly so that the second friction member 62 has the trend being adjacent to the first friction member 61 all the time.
As shown in Figure 4,5, this damping mechanism 6 can also be placed on spool 2.Sheathed described first friction member 61 and the second friction member 62 outside the end of spool 2, equally, on two surfaces that this first friction member 61 is relative with the second friction member 62, one of them surface is provided with circumferentially distributed profile of tooth concavo-convex 63, another surface is provided with the projection 64 highlighted towards this profile of tooth concavo-convex 63, and this first friction member 61 and the second friction member 62 remain the trend being close to.
This second friction member 62 is fixed on valve body 1, namely fix with valve body 1 and be connected, second friction member 62 is provided with profile of tooth concavo-convex 63 towards the face of the first friction member 61, first friction member 61 is socketed on described spool 2, and it is axially movable with spool 2, circumferentially positioned, namely the rotation of spool 2 can drive this first friction member 61 rotating in same direction.First friction member 61 is provided with projection 64 concavo-convex with profile of tooth 63 towards the face of described second friction member 62 and matches.This first friction member 61, second friction member 62 is annular element, and the external diameter of the internal diameter of this first friction member 61 and spool 2 matches, for irregular annular, therefore, this first friction member 61 is placed on spool 2, can with spool 2 rotating in same direction and can axially opposing movement.Spool 2 is cased with back-moving spring 65, this back-moving spring 65 is outside the first friction member 61 is relative to the opposite side of described second friction member 62, and one end of this back-moving spring 65 first is butted on the first friction member 61, the other end be butted on be fixed on spool 2 along the stator 66 radially extended of spool 2, this back-moving spring 65 makes described first friction member 61 have the trend being close to the second friction member 62 all the time.
The other end of this back-moving spring 65 can also be butted on the inner surface of valve gap 5 in fact, or is butted on valve rod 3, as long as making the second friction member 62 have the trend being close to all the time with the first friction member 61.Additionally those skilled in the art are also readily apparent that, it is possible to being that the first friction member 61 is fixed with valve gap 5 or valve body 1, the second friction member 62 is circumferentially positioned axially movable with valve rod or spool；Can also be that the first friction member 61 is circumferentially positioned axially movable with valve rod or spool, and the second friction member 62 is fixed with valve gap 5 or valve body 1.As long as the first friction member 61 and the second friction member 62 can have the trend being adjacent to all the time.It addition, this back-moving spring 65 can also be other setting, or other springs outside original spring 4 or valve gap can also be utilized.
Although the preferred embodiments of the present invention described in detail above, it is to be clearly understood that for a person skilled in the art, the present invention can have various modifications and variations.All make within the spirit and principles in the present invention any amendment, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
