Abstract
The utility model discloses a kind of burnt gas valve, including valve body, bonnet and the valve element that is arranged in valve body；Medium channel is provided with the bonnet, and is provided between bonnet and valve body valve seat；The valve seat end face fits to form sealing surface with valve element, and valve seat is provided with granular absorption plain cushion close to medium channel face, and granular absorption plain cushion includes the rubber layer of outer layer and the active carbon layer of internal layer；The rubber layer is provided with multiple adsorption holes.The solid particle in combustion gas can effectively be absorbed using the utility model, it is to avoid it enters and loses sealing surface, so as to extend the service life of valve.
Description
Technical field
The utility model is related to fuel gas pipeline field, specifically a kind of burnt gas valve.
Background technology
Current existing ball valve, semisphere valve and eccentric half-ball valve are by close between ball valve core or hemisphere valve element and valve seat
Envelope realizes the keying of valve, and valve element has friction in opening-closing process between valve seat.When these ball valves be widely used in
Fuel gas pipeline field, also referred to as burnt gas valve.And due to containing a certain amount of tiny solid particle medium in combustion gas, long-term
Use during, solid particle is gradually adsorbed on valve inwall and ball valve core, once and spool face has a large amount of
Grain, extremely easily causes scuffing sealing surface in opening-closing process, causes seal failure so as to cause leakage, finally results in safe thing
Therefore generation.
Utility model content
The utility model aims to provide a kind of burnt gas valve, and being easily adsorbed onto spool face to solve particle causes wear out failure
The problem of.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of burnt gas valve, it is characterised in that：Including valve body, bonnet and the valve element being arranged in valve body；The bonnet
Medium channel is inside provided with, and is provided between bonnet and valve body valve seat；The valve seat end face fits to form close with valve element
Front cover, and valve seat is provided with granular absorption plain cushion close to medium channel face, granular absorption plain cushion includes the rubber layer of outer layer and interior
The active carbon layer of layer；The rubber layer is provided with multiple adsorption holes.
Further, the valve seat includes the soft seal circle in hard sealing surface and fixed valve base, in hard sealing surface upper end
It is provided with soft seal circle fixed groove.
Further, the soft seal circle is triangle explosion-proof ring, and in the fixed fixture block of soft seal circle side setting.
Further, the granular absorption plain cushion bottom, which is provided with connecting plate, connecting plate, is provided with tapped blind hole, and leads to
Screw is crossed to interfix with valve seat.
Further, the valve seat tail end is provided with the counter sink being adapted to absorption plain cushion tapped blind hole.
Further, the counter sink top is provided with seal O-ring.
The beneficial effects of the utility model are：Valve seat of the present utility model is setting particle to inhale close to medium channel one side
Attached plain cushion, when combustion gas is by absorption plain cushion, the solid particle contained in combustion gas is attached to activity by the adsorption hole of rubber layer
In layer of charcoal, so as to be efficiently absorbed, it is to avoid enter sealing surface, so as to avoid abrasion, increase the service life.
Secondly, valve seat of the present utility model both contains hard sealing surface, while being also provided with soft seal circle in hard sealing, together
When form soft and hard seal, improve sealing effectiveness.
Brief description of the drawings
Fig. 1 is the structural representation for the burnt gas valve that the utility model is provided.
Fig. 2 is the close-up schematic view at I in Fig. 1.
Marked in figure：1 it is bonnet, 2 be valve element, 3 be valve seat, 4 be soft seal circle, 5 be fixed fixture block, 6 is granular absorption
Plain cushion, 7 are medium channel.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-Figure 2, a kind of burnt gas valve, including valve body, bonnet 1 and the valve element 2 that is arranged in valve body；Institute
State and medium channel 7 is provided with bonnet 1, and be provided between bonnet 1 and valve body valve seat 3；The end face of valve seat 3 and valve element
2 laminatings form sealing surface, and valve seat 3 is provided with granular absorption plain cushion 6 close to the face of medium channel 7, and granular absorption plain cushion 6 includes outer
The rubber layer of layer and the active carbon layer of internal layer；The rubber layer is provided with multiple adsorption holes.
The valve seat 3 includes the soft seal circle 4 in hard sealing surface and fixed valve base 3, is provided with hard sealing surface upper end soft
The fixed groove of sealing ring 4.The soft seal circle 4 is triangle explosion-proof ring, and in the fixed fixture block 5 of the side of soft seal circle 4 setting.
The bottom of granular absorption plain cushion 6, which is provided with connecting plate, connecting plate, is provided with tapped blind hole, and by screw with
Valve seat 3 interfixes.The tail end of valve seat 3 is provided with the counter sink being adapted to absorption plain cushion tapped blind hole.On the counter sink
Portion is provided with seal O-ring.
In actual use, combustion gas is passed into from the entrance of medium channel 7, when granular absorption plain cushion 6 is passed through in combustion gas,
The solid particle contained in combustion gas is attached on active carbon layer by the adsorption hole of rubber layer, so as to be efficiently absorbed, it is to avoid enter
Enter to sealing surface, so as to avoid abrasion, increase the service life.
After actual use all the year round, valve can be dismantled granular absorption plain cushion 6 is replaced, without to integral valve
Door is scrapped, and saves financial cost.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
