Abstract
The utility model discloses a novel all-welded ball valve with a singe welding seam and a self-pressure-relieving function of a middle cavity, which comprises a valve body, wherein a ball body is arranged in the valve body, floating valve seats are respectively arranged between the inlet end of the valve body and the ball body as well as between the outlet end of the valve body and the ball body, the valve seat at the inlet end is a one-way sealing valve seat, and the valve seat at the outlet end is a two-way sealing valve seat. A valve seat sealing ring is pushed to the ball body through the pretightening force loaded by a spring under ordinary medium work conditions, so the valve seat sealing ring is tightly attached to the surface of the ball body, and the pretightening sealing effect is realized. When the medium pressure exists between the middle cavity and the outlet end, the two-way sealing valve seat can also be pushed to the ball body through the double-piston effect to realize the sealing effect, when the pressure of the middle cavity and the outlet end is increased to 1.33 times of the rated pressure, the one-way sealing valve seat A can be pushed away, and the pressure is automatically relieved. The novel all-welded ball valve has the advantages of simple structure and higher safety and is convenient to use.
Description
Technical field
The utility model relates to a kind of seal ball-valve, relates in particular to a kind of novel single-pass welding lumen from the pressure release all-welded ball valve.
Background technique
In short supply along with world energy sources, oil, natural gas extraction are being quickened, and oil, rock gas long-distance transport pipes are built to be increased, and the transfer line construction of product oil is being accelerated.Seal ball-valve is the indispensable pipe fitting of the transfer line of product oil.
The seal ball-valve complex structure of the transfer line of product oil of the prior art, use inconvenience, and Security is not high.
The model utility content
The purpose of this utility model provides a kind of novel single-pass welding lumen simple in structure, easy to use, safe from the pressure release all-welded ball valve.
The purpose of this utility model is achieved through the following technical solutions:
Novel single-pass welding lumen of the present utility model is from the pressure release all-welded ball valve, comprise valve body, be provided with spheroid in the described valve body, be respectively equipped with unsteady valve seat between the import of described valve body and outlet end and the described spheroid, the valve seat of entrance point is the one-way sealing valve seat, and the valve seat of outlet end is the two way sealed valve seat.
The technological scheme that is provided by above-mentioned the utility model as can be seen, novel single-pass welding lumen described in the utility model is from the pressure release all-welded ball valve, owing to be respectively equipped with unsteady valve seat between the import of valve body and outlet end and the described spheroid, the valve seat of entrance point is the one-way sealing valve seat, and the valve seat of outlet end is the two way sealed valve seat.By spring-loaded pretightening force valve seat insert being pushed to spheroid under the medium operating mode usually, make it to fit tightly with spherome surface, play the pretension seal action.When lumen and outlet end have pressure medium, also can push the two way sealed valve seat to spheroid by the double-piston effect and play seal action, when lumen and outlet end pressure rise to 1.33 times of rated pressures, can push one-way sealing valve seat A open, releasing pressure automatically.Property simple in structure, easy to use, safe is higher.

Fig. 4 is a greasing view in the utility model.
Embodiment
Novel single-pass welding lumen of the present utility model is from the pressure release all-welded ball valve, its preferable embodiment as shown in Figures 1 to 4, comprise valve body 1, be provided with spheroid 2 in the valve body 1, be respectively equipped with unsteady valve seat 3,4 between the import of valve body 1 and outlet end and the spheroid 2, the valve seat 3 of entrance point is the one-way sealing valve seat, and the valve seat 4 of outlet end is the two way sealed valve seat.
Described valve body 1 is provided with greasing hole 5, and is provided with grease pouring valve 6 at described greasing hole place, and greasing hole 5 is run through valve seat 3,4 and communicated with fitting surface gap between spheroid 2 and the valve seat 3,4.
Sealing configuration between spheroid 2 and the valve seat 3,4 is the soft or hard compound sealing structure.
Working principle of the present utility model is:
As shown in Figure 1, novelly two block the ball valve of releasing and be provided with two valve seats, be designed to floating structure, a seat design is the unidirectional valve seat of single piston effect, and another seat design is the structure of two-way double-piston effect.
By spring-loaded pretightening force valve seat insert being pushed to spheroid under the medium operating mode usually, make it to fit tightly with spherome surface, play the pretension seal action.At entrance point,, when entrance point has pressure medium, can push the one-way sealing valve seat to spheroid and play seal action because area difference forms the one-way sealing valve seat of single piston effect; At outlet end,, when lumen and outlet end have pressure medium, can push the two way sealed valve seat to spheroid 2 and play seal action because area difference forms the two way sealed valve seat of double-piston effect;
When lumen and outlet end have pressure medium, also can push the two way sealed valve seat to spheroid by the double-piston effect and play seal action, when lumen and outlet end pressure rise to 1.33 times of rated pressures, can push one-way sealing valve seat A open, releasing pressure automatically.
Ball valve adopts double seal, valve seat location at ball valve is provided with grease pouring valve, in case valve seal lost efficacy, the seal gease of can annotating plays the function of urgent sealing, sealing configuration is the soft or hard compound sealing structure, when the pipeline breaking out of fire, when soft seal was lost efficacy, two valve seats were pushed to spheroid, metal to metal forms hard sealing and plays seal action, thereby has stoped the further expansion of fire.
The beneficial effects of the utility model are:
1, also realizing releasing pressure automatically when pressure medium in the body cavity rises to 1.33 times of rated pressures under the situation that lumen Decompression valves (safety valve) is not installed, saved a safety valve, reduced by a leakage point simultaneously.
2, this ball valve adopts two way sealed, sealing is reliable, and be provided with grease pouring valve in the valve seat location of ball valve, in case prolonged valve seal lost efficacy the seal gease of can annotating, play the function of sealing, this structure is the soft or hard compound sealing structure, when the pipeline breaking out of fire, when soft seal was lost efficacy, metal hard-sealing plays seal action, thereby has stoped the further expansion of fire.
3. the project organization of ball valve has reduced wall thickness according to the requirement of standard, thereby has played the effect of material-saving.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
