Description
Technical field
The present invention relates to a kind of power station stop valve.
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 the empty gas and water of control, steam, various corrosivity to be situated between
The flowing of all kinds 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 the use that adjusts and throttle.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 the change due to valve seat port and the stroke direct proportionality of 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 subject to larger external impacts, while the leakproofness of valve body is also impacted.
The content of the invention
The present invention mainly solves the technical problem present in the prior art, so as to provide a kind of power station stop valve.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of power station stop valve, comprising a valve body, valve body is equipped with a left flange and a right flange, and a pair of of gold is additionally provided with valve body
Belong to shrapnel, the top of valve body is equipped with a valve seat, a valve rod is rotationally equipped with valve seat, it is close that valve rod and valve base chamber are equipped with a metal
Seal and a ceramic seal circle, are fixedly connected with a sealing cover on valve rod, sealing cover is pressed against metal o-ring and ceramic seal circle
On, the outer wall of valve rod is additionally provided with multiple positioning pins.
As preferred embodiments of the present invention, the ceramic seal circle is located on the inside of metal o-ring.
As preferred embodiments of the present invention, the sealing cover is plastic lid.
The power station stop valve of the present invention is provided with a pair of of metal clips in the outer surface of valve body, when valve body is subject to external impacts
When metal clips can absorb most impact force, protection valve body is against damages.The valve rod and valve base chamber of the shut-off valve
There is provided a metal o-ring and a ceramic seal circle, such collocation using can effective poppet leakproofness, prolong
The service life of long valve.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is attached drawing needed in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without creative efforts, can be with

Fig. 1 is the dimensional structure diagram of the power station stop valve of the present invention.
Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1, a kind of power station stop valve 1, comprising a valve body 10, valve body 10 is equipped with a left 11 and one right method of flange
Orchid 12, is additionally provided with a pair of of metal clips 13 on valve body 10, 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, be equipped with a metal o-ring 21 and a ceramic seal circle 22 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.
As to further improvement of the present invention, the ceramic seal circle 22 is located at the inner side of metal o-ring 21.
As to further improvement of the present invention, the sealing cover 30 is plastic lid.
The power station stop valve of the invention is provided with a pair of of metal clips in the outer surface of valve body, when valve body is subject to external impacts
When metal clips can absorb most impact force, protection valve body is against damages.The valve rod and valve base chamber of the shut-off valve
There is provided a metal o-ring and a ceramic seal circle, such collocation using can effective poppet leakproofness, prolong
The service life of long valve.
Only illustrate the mentality of designing of the present invention in one embodiment above, in the case where system allows, the present invention can
To expand to while external more function modules, so as to extend its function to greatest extent.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
