Description

Upper-mounting type ball valve
Technical field
The utility model relates to a kind of valving, particularly a kind of upper-mounting type ball valve.
Background technique
Ball valve has compact structure as a kind of common valve, and is in light weight, and fluid resistance runs off less and maintenance operation advantage easily, therefore uses very extensive.Its valve body of upper-mounting type ball valve is an integrated type, and spheroid is packed into from the top of valve body.Compare with the ball valve of left and right valve body, reduced the possible leakage point in a place, this is again one of its advantage.
Its seal ring of existing upper-mounting type ball valve is located on the valve seat, and valve seat is fixed on the valve body.Sealability between seal ring and the spheroid is unadjustable.In addition, ball valve in use because spheroid and seal ring produce friction, after use a period of time, can make valve cause leakage after the wearing and tearing, descends because of ring wear causes sealability, has influenced use, even has scrapped.
The model utility content
The purpose of this utility model is to overcome above technological deficiency, and a kind of dress formula sealing load adjustable ball valve of going up is provided, and the sealability of its seal ring can be regulated, and prolongs the repair cycle and the working life of ball valve.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of upper-mounting type ball valve, comprise valve body, spheroid, valve seat, seal ring, the ball drive device, two valve seats are located at the medium inlet passage of valve and the inboard of outlet passage respectively, seal ring is fixed on the valve seat and cooperates with ball seal, it is characterized in that: valve seat is along the removable setting of medium channel direction, valve seat is the inclined-plane that tilts to the medium channel inboard away from the end face of an end of spheroid, medium channel is being provided with a plurality of screws with corresponding section, valve seat inclined-plane, be provided with wedge pin and adjusting screw in the screw, wedge pin is provided with an end and the valve seat inclined-plane on inclined-plane and conflicts, and the other end and adjusting screw are conflicted.
The utility model further is set to: valve seat is divided into valve seat body and valve seat supporting, seal ring is located on the valve seat body, and the valve seat inclined-plane is located in the valve seat supporting, is provided with damping spring between valve seat body and the valve seat supporting, damping spring one end conflict valve seat body, the other end prop up the valve seat supporting.
Seal ring of the present utility model is located on the valve seat, valve seat is located at the medium channel inboard versatilely and is provided with the inclined-plane, medium channel is being provided with a plurality of screws with corresponding section, valve seat inclined-plane, be provided with wedge pin and adjusting screw in the screw, therefore can be by the rotation adjusting seal ring of adjusting screw and the sealing load between the spheroid.Valve seat can be divided into the supporting of valve seat body and valve seat in addition, be provided with damping spring between valve seat body and the valve seat supporting, when adjusting screw compresses seal ring like this, can play the effect of buffering.
Further describe below in conjunction with accompanying drawing and embodiment
Description of drawings
Fig. 1 is the utility model specific embodiment half sectional view;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the utility model specific embodiment partial enlarged view;
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of upper-mounting type ball valve comprises valve body, spheroid 9, valve seat, seal ring 8, ball drive device.The ball drive device can but to be not limited to be a kind of in electronic, manual, the Pneumatic actuator, present embodiment adopts manual operating device.Spheroid 9 is located at valve inner, is in transmission connection by valve rod and handwheel 10.
The both sides of spheroid 9 respectively are provided with the seal ring 8 that is sealed and matched with spheroid 9, and seal ring 8 is fixed on the valve seat.Valve seat is that medium channel 1 can be provided with a plurality of screws as required with corresponding section, valve seat inclined-plane to the inclined-plane of the inboard inclination of medium channel away from the end face of an end of spheroid 9.Respectively establish 4 screws in the both sides of valve body in the present embodiment.Be provided with wedge pin 11 and adjusting screw 12 in the screw, be provided with lock screw 4 outside the adjusting screw 12, this lock screw 4 plays seal action.Wedge pin 11 is provided with an end and the valve seat inclined-plane on inclined-plane and conflicts, and the other end and adjusting screw 12 are conflicted.Be provided with O RunddichtringO 8 between valve seat and medium channel 1 inboard.When seal ring 8 with spheroid 9 because friction, during the sealing effect variation, can rotate adjusting screw 12, adjusting screw 12 spirals move, and then extruding wedge pin 11, wedge pin 11 cooperates with the extruding of valve seat inclined-plane by the inclined-plane, promotes valve seat and moves to spheroid 9 directions, strengthens the sealing effect between seal ring 8 and the spheroid 9.The utility model can be regulated the sealing load between seal ring 8 and the spheroid 9, thereby has overcome the uncontrollable defective of sealing load between existing upper-mounting type ball valve seal ring and the spheroid.Adjusting screw 12 is conflicted by wedge pin 11 inclined-planes and valve seat inclined-plane, can increase area of contact, the convenient adjusting.
As a kind of improvement mode of execution of the present utility model, valve seat is divided into valve seat body 7 and valve seat supporting 2.Seal ring 8 is located on the valve seat body 7, and the valve seat inclined-plane is located in the valve seat supporting 2.Be provided with O RunddichtringO 6,3 between valve seat body 7 and valve seat supporting 2 and medium channel 1 inboard.Valve seat body 7 supports 2 opposing end faces with valve seat and is provided with ring-shaped step, and valve seat supports 7 corresponding positions and is provided with annular groove, and ring-shaped step embeds in the annular groove.Be provided with damping spring 5 between valve seat body 7 and the valve seat supporting 2, damping spring 5 one end conflict valve seat bodies 7, the other end prop up valve seat supporting 2.Like this, when damping spring 5 supports 2 squeeze valve seat bodies 7 at valve seat, can play buffer function.
Certainly, the utility model is not limited only to above-mentioned specific embodiment, and any improvement to the utility model unsubstantiality all should be within protection domain of the present utility model.
