Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of heavy caliber high pressure cast steel ball valve.
Background technique
Heavy caliber high pressure cast steel ball valve is that one can be used in high pressure operating mode, and is applicable to the ball valve in oil or chemical pipeline.
Traditional heavy caliber high pressure cast steel ball valve mainly comprises valve body, the valve gap be connected with valve body, be located at the medium inlet passage on valve body, medium flow pass and connection chamber, be provided with in connection chamber and impel medium inlet passage and medium to flow out channel conductive or closed spheroid, medium inlet passage or be provided with valve seat between medium flow pass and spheroid, valve gap is provided with and extends in connection chamber and the valve rod be connected with spheroid, and valve rod is provided with the driving source of actuate valve stem relative to the be connected the other end of one end of spheroid.
The valve rod of this type of ball valve can be subject to the leverage of spheroid, and valve rod is subject to larger torsion, and the working life of valve rod is shorter, and long use can cause valve rod to be out of shape or bend, and causes valve rod to be scrapped.
Summary of the invention
For the deficiency that prior art exists, the utility model provides and a kind ofly extends the working life of valve rod, the heavy caliber high pressure cast steel ball valve of good airproof performance.
For achieving the above object, the utility model provides following technological scheme: a kind of heavy caliber high pressure cast steel ball valve, include valve body, the valve gap be connected with valve body, be located at the medium inlet passage on valve body, medium flow pass and connection chamber, be provided with in connection chamber and impel medium inlet passage and medium to flow out channel conductive or closed spheroid, medium inlet passage or be provided with valve seat between medium flow pass and spheroid, valve gap is provided with and extends in connection chamber and the valve rod be connected with spheroid, valve rod is provided with the driving source of actuate valve stem relative to the be connected the other end of one end of spheroid, it is characterized in that: described valve gap is provided with the construction opening installed for valve rod relative to the other end being connected one end with valve body, construction opening place is provided with gland, ball support cover is provided with between gland and spheroid, axial one end and the gland of this ball support cover are conflicted, the other end spheroid is fitted, bearing is respectively equipped with between one end that described ball support cover and spheroid are fitted and valve rod and spheroid.
Adopt technique scheme; by arranging ball support cover between gland and spheroid; spheroid leverage is in use put by valve rod being forwarded to ball support; thus protection is implemented to valve rod; prevent valve rod from bending or distortion; thus extend the working life of valve rod, ball support cover and between spheroid and valve rod the setting of bearing ball support can be avoided overlap and rub between valve rod and spheroid, thus further spheroid and valve rod enforcement to be protected.
The utility model is set to further: be provided with fixture block between gland and ball support overlap, described gland and ball support cover and be respectively equipped with seal ring between valve rod and valve body.
Adopt technique scheme, compact structure is set like this, good airproof performance.
The utility model is further set to: be provided with sealing block between valve seat and spheroid, and valve seat is provided with spring relative to arranging between the other end of sealing block one end and valve body.
Adopt technique scheme, the sealing that can ensure between valve seat and spheroid is set like this.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Embodiment
As Fig. 1, a kind of heavy caliber high pressure cast steel ball valve shown in Fig. 2, include valve body 1, the valve gap 2 be connected with valve body 1, be located at the medium inlet passage 11 on valve body 1, medium flow pass 12 and connection chamber 13, be provided with in connection chamber 13 and impel medium inlet passage 11 and medium flow pass 12 conducting or closed spheroid 3, medium inlet passage 11 or be provided with valve seat 4 between medium flow pass 12 and spheroid 3, valve gap 2 is provided with and extends in connection chamber 13 and the valve rod 5 be connected with spheroid 3, valve rod 5 is provided with the driving source 6 of actuate valve stem 5 relative to the be connected the other end of one end of spheroid 3, driving source 6 can be handle or motor, valve gap 2 is provided with the construction opening 21 installed for valve rod 5 relative to the other end being connected one end with valve body 1, construction opening 21 place is provided with gland 7, be provided with ball support between gland 7 and spheroid 3 and overlap 71, axial one end and the gland 7 of this ball support cover 71 are conflicted, the other end spheroid 3 is fitted, bearing 72 is respectively equipped with between ball support cover 71 and spheroid 3 one end of fitting and valve rod 5 and spheroid 3.In such scheme; 71 are overlapped by arranging ball support between gland 7 and spheroid 3; spheroid 3 leverage is in use made to overlap on 71 by valve rod 5 being forwarded to ball support; thus protection is implemented to valve rod 5; prevent valve rod 5 from bending or distortion; thus extend the working life of valve rod 5, ball support cover 71 and between spheroid 3 and valve rod 5 setting of bearing 72 ball support can be avoided overlap between 71 and valve rod 5 and spheroid 3 rub, thus further spheroid 3 and valve rod 5 enforcement to be protected.
