Technical field
The utility model relates to a kind of ball valve, specifically refers to a kind of whole-welding type forged steel fixing ball valve.
Background technique
Ball valve is a kind of common Flow valve.Its structure generally comprises valve body, valve gap, spheroid, valve rod and operating device composition, wherein operating device and valve rod are linked, actuate valve stem drives spheroid to rotate, and complete the switching motion of ball valve, a main application fields of ball valve is exactly oil, rock gas field.The types of transportation of current oil, rock gas is to Cemented filling future development, and Cemented filling just progressively becomes the important transportation form of oil, rock gas, and Cemented filling can alleviate the pressure of railway transport, and safer, economical.
In prior art, for oil, the ball valve major part of rock gas adopts split valve body, split valve body assembles finally by bolt and forms, split valve body is in order to reach the seal standard of industry, generally adopt secondary seal mechanism, complex structure, maintain and replace bothers, therefore, for this kind of situation, occur that all-welded ball valve solves this technology drawback in recent years, but what current all-welded ball valve sealing mainly adopted is hard sealing mechanism, sealing is not fine, when after valve closing, a small amount of gas medium is still had to leak, it is optimal for reaching " zero leakage " in theory, but say it can only is that leakage rate is the smaller the better from technical standpoint, also cannot really accomplish " zero leakage ".In addition, in some cases, when after throttle down, need to discharge rock gas remaining in main pipeline, this cannot realize in current all-welded ball valve.
Model utility content
The shortcoming and defect that the utility model exists for prior art, object is a kind of good airproof performance of exploitation, and under particular demands occasion can vent valves close after the welding ball valve of the remaining rock gas of main pipeline.
In order to realize final purpose of the present utility model, intend by the following technical solutions:
Full welding type forged steel fixing ball valve, comprise middle body (3), spheroid (5) is provided with in described middle body (3), body cap board component (8) is set on the upside of middle body, be provided with valve rod (9) in body cap board component (8), valve rod (9) is connected with spheroid (5) through body cap board component (8).
Described middle body (3) both sides are welded with left valve barrel (2) and right valve barrel (6) respectively, described left valve barrel (2) and right valve barrel (6) upside are respectively arranged with corresponding left grease pouring valve (20) and right grease pouring valve (60), left valve barrel (2) and right valve barrel (6) outside are welded with corresponding left sleeve (1) and right sleeve (7) respectively, and described left sleeve (1) and right sleeve (7) are welded with corresponding left stop valve (10) and right stop valve (70) respectively.
Described middle body (3) downside is equipped with blowdown valve (4), in order to the clean blowdown that centered body (3) is inner.
Further, all middle body (3) of described left valve barrel (2) and right valve barrel (6), left sleeve (1) and right sleeve (7), left grease pouring valve (20) and right grease pouring valve (60), left stop valve (10) and right stop valve (70) is with reference to being arranged symmetrically with.
In order to better realize soft seal effect, in described left valve barrel (2), right valve barrel (6), spheroid (5) side being provided with cylindrical hole, being provided with helical spring (14) in cylindrical hole, the free end of helical spring (14) contacts with valve seat (12).
For convenience of grease pouring valve greasing, described left grease pouring valve (20), right grease pouring valve (60) lower end are connected with spheroid (5) outer spherical surface by being arranged on pipeline in valve seat (12).
For increasing sealing effect, the position that described left valve barrel (2) contacts with valve seat (12) with right valve barrel (6) is provided with O RunddichtringO (13).
For realizing sealing effect, on described valve seat (12), spheroid (5) side, direction being provided with annular groove, in annular groove, being provided with rubber seal (11).
Further, the uniform arrangement of described cylindrical hole, is partially arranged on left valve barrel (2), right valve barrel (6).
The beneficial effects of the utility model are:
1. the utility model is on existing hard sealing technique basis, add soft sealing structure, when there is the situation of poor sealing in valve, can by grease pouring valve to soft seal position rubber seal filling seal grease, play the function of positive confinement, because this ball valve is soft, hard sealing structure, when pipeline breaking out of fire, also can seal, thus stop fire to spread toward downstream line;
2. the utility model is provided with spring at valve seat and valve body, and when ball valve body cavity pressure exceedes this valve rated working pressure, valve body cavity pressure is greater than initial tension of spring, valve seat retrude, the endoceliac pressure of automatic-discharging, ensures the use safety of valve;
3. the utility model is being provided with blowdown valve at body base, regularly to blowdown clean in valve body, and then can ensure the sealing effect of valve body;
4. the utility model ball valve two ends sleeve on be provided with stop valve, can according to actual use occasion demand, rock gas remaining in pipeline after valve closing is discharged.
