Description
Technical field
The utility model is related to a kind of power station stop valves.
Background technology
The opening and closing element of shut-off valve is the flap of stopper, and sealing is above in plane or the extra large conical surface, center line of the flap along valve seat
It is for linear motion.The forms of motion of valve rod also has lifting rotation rod-type to can be used for controlling empty gas and water, steam, various corrosivity and is situated between
The flowing of the various types fluid such as matter, mud, oil product, liquid metal and radiating medium.Therefore, such cut-off of shutting off
Valve valve is highly suitable as cutting off or adjusting and throttling is used.Since the valve rod of such valve is turned on and off stroke relatively
It is short, and there is very reliable cutting function, and due to the stroke direct proportionality of the variation of valve seat port and flap, it is non-
It is very suitable for the adjusting to flow.The valve body impact resistance and leakproofness for the power station stop valve being commonly used are all relatively
Weak, valve body is easily damaged when valve body is by larger external impacts, while the leakproofness of valve body is also impacted.
Utility model content
The utility model is mainly the technical problem solved present in the prior art, to provide a kind of power station stop valve.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals:
A kind of power station stop valve, including a valve body, valve body is equipped with a left flange and a right flange, and one is additionally provided on valve body
To metal clips, the top of valve body is equipped with a valve seat, and a valve rod is rotationally equipped on valve seat, and valve rod and valve base chamber are equipped with a gold medal
Belong to sealing ring and a ceramic seal circle, is fixedly connected with a sealing cover on valve rod, sealing cover is pressed against metal o-ring and ceramics are close
In seal, the outer wall of valve rod is additionally provided with multiple positioning pins.
As the utility model preferred embodiment, the ceramic seal circle is located on the inside of metal o-ring.
As the utility model preferred embodiment, the sealing cover is plastic lid.
The power station stop valve of the utility model is provided with a pair of of metal clips in the outer surface of valve body, when valve body is by external force
Metal clips can absorb most impact force when impact, and protection valve body is against damages.The valve rod and valve of the shut-off valve
Seat between be provided with a metal o-ring and a ceramic seal circle, it is such collocation using can effectively poppet sealing
Property, extend the service life of valve.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
As shown in Figure 1, a kind of power station stop valve 1, including a valve body 10, valve body 10 is equipped with a left flange 11 and a right method
Orchid 12, a pair of of metal clips 13 is additionally provided on valve body 10, and the top of valve body 10 is equipped with a valve seat 14, is rotationally set on valve seat 14
There is a valve rod 20, a metal o-ring 21 and a ceramic seal circle 22 are equipped between valve rod 20 and valve seat 14, it is fixed on valve rod 20 to connect
A sealing cover 30 is connect, sealing cover 30 is pressed against on metal o-ring 21 and ceramic seal circle 22, and the outer wall of valve rod 20 is additionally provided with more
A positioning pin 31.
It is further improved as to the utility model, the ceramic seal circle 22 is located in metal o-ring 21
Side.
It is further improved as to the utility model, the sealing cover 30 is plastic lid.
The power station stop valve of the utility model is provided with a pair of of metal clips in the outer surface of valve body, when valve body is by external force
Metal clips can absorb most impact force when impact, and protection valve body is against damages.The valve rod and valve of the shut-off valve
Seat between be provided with a metal o-ring and a ceramic seal circle, it is such collocation using can effectively poppet sealing
Property, extend the service life of valve.
The mentality of designing for only illustrating the utility model in one embodiment above, in the case where system allows,
The utility model can be extended to while external more function modules, to extend its function to greatest extent.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
