Description
Technical field
The present invention relates to valve, be meant the metal seal ball valve of HTHP especially.
Background technique
Our valve industry has obtained development fast at present; But existing and the similar valve of the present invention since unreasonable structure exist below some problems: 1, its spool ball and valve base sealing material employing hard chrome, alloyed steel and Hardmetal materials; Under high temperature, high pressure and high particle operating mode, washed away easily, cavitated, abraded, and caused seal failure; 2, valve seat and valve body branch are arranged, and make valve seat increase sealing with valve body like this, very easily cause the leakage of valve; 3, the sealing between valve body, auxiliary valve body and the valve rod is revealed easily.
Summary of the invention
The present invention overcomes the existing technology defective, provide a kind of rational in infrastructure, open and close flexibly, efficient is high, the novel integrated high-temperature high-pressure metal seal ball valve of good sealing effect.
In order to realize above purpose; The present invention adopts following technological scheme: integrated high-temperature high-pressure metal seal ball valve; Include valve rod, valve body, valve seat and spool ball, described valve seat and valve body are wholely set, and valve seat and valve body one joint cross setting are ripple struction; Described valve body is divided into main valve body and auxiliary valve body; Described main valve body cooperates the conducting that constitutes ball valve and closes with the spool ball; Be connected through bolt between described auxiliary valve body and the main valve body; Both joining places of said main valve body and auxiliary valve body are respectively arranged with corresponding circular groove; Two circular grooves constitute the annular receiving hole that cross section is
shape; Be provided with shape of cross section and the suitable O-ring seal of annular receiving hole shape of cross section in the annular receiving hole, the inner side surface of O-ring seal is provided with annular cavity; Said valve rod passes auxiliary valve body and is connected on the spool ball; Be provided with two groups of ring-shaped chambers between said valve rod and the auxiliary valve body; Wherein be provided with the tungsten carbide metal pad in the ring-shaped chamber near spool ball side; Be covered with the final controlling element platform on another cavity volume, be provided with the metal guide pin bushing between this final controlling element platform and the valve rod, be disposed with ceramic ring pad, the fine braided ring pad of carbon, ceramic ring pad, graphite, the fine braided ring pad of carbon, press block and butterfly spring in this cavity volume.
Through taking such scheme, cancelled a part valve seat on the valve, reduce the structural design of Sealing; Guarantee sealing reliability, improved the product precision, effectively promoted product hermeticity ability and working life; This in addition structure has guaranteed the self-compensating of valve after alternately being out of shape under the thermal stress circulation; Having solved the at high temperature necessary specific pressure of sealing surface increases, thereby realizes the oneself being compensated after the ball valve wearing and tearing, has guaranteed sealing.In addition can fine solution sealing problem; Be provided with the annular receiving hole of
shape between main valve body particularly of the present invention and the auxiliary valve body; Seal through shape of cross section and the suitable O-ring seal of annular receiving hole shape of cross section then; And the inner side surface of this O-ring seal is provided with annular cavity; Pressure in annular cavity is high more like this, and then the sealing effect of seal ring is good more, in addition; Ball valve is under stress or cyclic thermal stres effect, and seal ring can not produce dislocation.At last, make this valve stem seal effective, be not easy to eject, long service life wherein is provided with the tungsten carbide metal pad and can effectively stops solid particle and fiber to get into another cavity volume, again valve rod is played the effect of reducing friction in rotary course simultaneously; The fine braided ring pad of two other ceramic ring pad folder a slice carbon; The ceramic ring pad forms dual obstruct because of its heat conductivity is low to oxygen amount of money heat wave like this, utilizes the minimum characteristics of ceramic ring pad expansion coefficient that the fixed guide effect is played in the valve rod lower end simultaneously, and the metal guide pin bushing plays the guide securement effect to the valve rod upper end; The metal guide pin bushing is set in addition like this; Make metal guide pin bushing stow away from heat, be out of shape for a short time, improve guiding accuracy.
Below in conjunction with accompanying drawing the present invention is done further explain
