Abstract
The invention discloses a sealing structure for a packless self-compensation sealing valve. The sealing structure comprises a valve body, a valve rod, a spring base, a spring, a spring retainer ring and a movable ring energy-accumulating component, wherein the valve rod is inserted into the valve body, the spring base is fixed on the valve rod; the spring, the spring retainer ring and the movable ring energy-accumulating component are arranged on the spring base in a way of being connected in sequence; the spring, the spring retainer ring and the movable ring energy-accumulating component sleeve between the valve rod and the valve body respectively. By adopting the sealing structure, the opening and closing torques of the valve can be reduced, and wear is reduced; friction seal of a packing and the valve rod in the prior art is replaced by end face seal of a movable ring and a static ring, so that the packing is not needed; moreover, the sealing structure has the advantages of simple structure, sealing reliability, freeness from maintenance and long service life.
Description
Technical field
The present invention relates to sealing configuration, particularly a kind of for the sealing configuration without filler self-compensation sealed valve.
Background technique
Valve rod is the part of input opening/shutting valve, in prior art, the sealing of valve rod and valve body is that filler is put into valve and valve body, and because valve rod is rotary work, time length will rub with filler, thereby need again compress Gland in case stopping leak reveals, increased the work of a lot of maintenances; If buried pipeline valve just can not compress Gland again, thereby cannot prevent from having revealed, greatly shorten working life.
Summary of the invention
The object of this invention is to provide a kind of for the sealing configuration without filler self-compensation sealed valve, reduced valve keying moment, reduced wearing and tearing; The filler of prior art and valve rod is friction sealed, change rotating ring and stationary ring end face seal into, without filler, and simple in structure, sealing is reliable, avoid safeguarding, long service life.
In order to realize above object, the present invention is achieved by the following technical solutions:
For the sealing configuration without filler self-compensation sealed valve, comprise valve body and be inserted in the valve rod in valve body, be characterized in, also comprise: spring seat, it is fixed on valve rod;
Connect and be arranged on spring, check ring and the rotating ring accumulation of energy parts on described spring seat successively;
Described spring, check ring and rotating ring accumulation of energy parts are nested with respectively between valve rod and valve body;
Described rotating ring accumulation of energy parts comprise: rotating seat;
Accumulation of energy seal ring, it is arranged between rotating seat and valve rod, and is positioned on check ring.
Described rotating ring accumulation of energy parts also comprise rotating ring and the stationary ring being successively set on rotating seat.
Sealing structure also comprises gland, and it is enclosed within valve rod outside and is connected with valve body, and this gland is pushed down stationary ring.
Between described rotating ring and valve rod, be provided with rotating ring O type circle.
Described stationary ring and gland are provided with some stationary ring O type circles.
Described rotating ring adopts hard material to make.
Described stationary ring adopts graphite material to make.
The present invention compared with prior art, has the following advantages:
The present invention reduced valve keying moment, reduced wearing and tearing; The filler of prior art and valve rod is friction sealed, change rotating ring and stationary ring end face seal into, without filler, and simple in structure, sealing is reliable, avoid safeguarding, long service life.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram for the sealing configuration without filler self-compensation sealed valve of the present invention;
Fig. 2 is the partial enlarged drawing of accumulation of energy seal ring of the present invention.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, a kind of for the sealing configuration without filler self-compensation sealed valve, comprise valve body 1, be inserted in the valve rod 2 in valve body 1, spring seat 3, it is fixedly nested with on valve rod 2; Connect and be arranged on spring 4, check ring 5 and the rotating ring accumulation of energy parts on described spring seat 3 successively; Described spring 4, check ring 5 and rotating ring accumulation of energy parts are nested with respectively between valve rod 2 and valve body 1; Described rotating ring accumulation of energy parts comprise: rotating seat 61; Accumulation of energy seal ring 62, it is arranged between rotating seat 61 and valve rod 2 (referring to Fig. 2), and is positioned on check ring 5, and check ring 5 can be distributed to spring force on accumulation of energy seal ring 62 uniformly; Be successively set on rotating ring 63 and stationary ring 64 on rotating seat 61, rotating ring 63 is interference fit with coordinating of rotating seat 61, and rotating ring 63 adopts hard material to make, and stationary ring 64 adopts graphite material to make.
Sealing structure also comprises gland 7 and gland seal pad 10, and gland 7 is enclosed within valve rod 2 outsides and is connected with valve body 1, and this gland 7 is pushed down stationary ring 64; Gland seal pad 10 is used for padding gland 7, is provided with rotating ring O type circle 8 between described rotating ring 63 and valve rod 2, and described stationary ring 64 is provided with two stationary ring O type circles 9 with gland 7.
During sealing, spring 4 is subject to deformation, promotes upwards top of accumulation of energy seal ring 62 and rotating seat 61, makes the end face of rotating ring 63 and stationary ring 64 bonded to each other, completes the sealing of valve body 1 and valve rod 2.
In sum, the present invention is a kind of for the sealing configuration without filler self-compensation sealed valve, reduced valve keying moment, reduced wearing and tearing; The filler of prior art and valve rod is friction sealed, change rotating ring and stationary ring end face seal into, without filler, and simple in structure, sealing is reliable, avoid safeguarding, long service life.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.Those skilled in the art, read after foregoing, for multiple modification of the present invention with to substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
