Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1 to Fig. 3, wherein, Fig. 1 is the structural representation of low torsion rotary valve base fixing ball valve in an embodiment of the present invention; Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1; Fig. 3 is the structure for amplifying schematic diagram at B place in Fig. 1.
The invention provides a kind of low torsion rotary valve base fixing ball valve, include valve seat 1, valve rod 2, spheroid 3 and valve body, valve body has sealing surface, valve seat 1 to be slidably mounted on valve body and to abut with sealing surface tightness, and valve body has upstream cavity.
When low torsion rotary valve base fixing ball valve is installed on after in pipe-line system, upstream cavity and upstream system connectivity, higher pressure is born in its inside.After valve rod 2 drives spheroid 3 to rotate, low torsion rotary valve base fixing ball valve can be made to open, thus be communicated with upstream system and downstream piping system.
In the present invention, also include force aid system, force aid system includes push rod 4 and one-way valve 5; Valve seat 1 offers power-assisted pipeline, one-way valve 5 is arranged on power-assisted pipeline, and power-assisted pipeline is communicated with upstream cavity; Push rod 4 abuts with one-way valve 5 and can promote one-way valve 5 and opens; One end of push rod 4 is provided with control flume, and push rod 4 is connected in control flume.
It should be noted that at this: valve rod 2 is provided with control flume, push rod 4 can be connected in control flume, when valve rod 2 rotates, valve rod 2 can depart from and move along its circumference from control flume, thus realize valve rod 2 rotate drive push rod 4 move, push rod 4 is connected with one-way valve 5, and push rod 4 moves and can control one-way valve 5 and open.
Be provided with force aid system, the high-pressure in upstream system can be utilized, when valve rod 2 rotates, the resistance of valve rod 2 can be reduced, be convenient to spheroid 3 and rotate.The present invention is designed by said structure, carries out special structural design make valve seat 1 in switching process to valve seat 1, and spheroid 3 adopts Spielpassung in valve rod 2 when connecting, and matching gap has the zero load amount of five degree.Valve seat 1 departs from sealing surface, and the rotary torsion that can reduce valve rod 2 reaches the effect to valve rod 2 power-assisted.
Concrete course of action of the present invention is: first rotated by valve rod 2 zero load and drive push rod 4 to push one-way valve 5 open; One-way valve 5 is opened rear power-assisted pipeline and is communicated with upstream cavity, and upstream pressure enters power-assisted pipeline, promotes valve seat 1 and departs from sealing surface; Treat that valve closing late gate chamber pressure balance rear valve base 1 pushes spheroid 3 sealing surface again to, thus reach sealing effect.
