Description
Technical field
The present invention relates to a kind of valve technology field, in particular to a kind of wear-resisting separable type fixing ball valve.
Background technique
Currently, common wear-resisting separable type ball valve, when processing the inner hole of lower valve rod of valve body, due in valve body lower valve rod
Hole is located at the lower part of valve body, processes down when processing the lower valve rod inner hole of valve body from the top of valve body, and the cutter processed in this way needs
Very long, the bottom that valve body could be reached from the top of valve body is come, and lower valve rod inner hole roughness is difficult to control, and leads to lower valve
Bar inner hole roughness is low.
Fluid pressure before valve, acts directly on lower valve rod, and lower valve rod is primarily located on sliding bearing, fluid pressure before valve
Power is mainly born by sliding bearing, thus valve seat is not subject to excessive pressure,
When work, the active force that pressure medium generates on sphere before valve keeps sphere mobile to valve seat, thus valve seat is born
Excessive pressure, torque is big, easily causes valve seat deformation, and the service life of ball valve shortens.
When containing solid particle in medium, in sphere standard-sized sheet and fully closed intermediate state, particle is easy to leak into down
In gap between the axle sleeve and lower valve rod in portion, and do not export, over time, particle is easy accumulation, lower valve rod and axle sleeve it
Between be easy blocked by particle.
Under hot operation state, due to thermal expansion effects, lower valve rod and axle sleeve are easy expansion, under expansion to a certain extent
It is stuck since the gap between valve rod and axle sleeve is zero.Lower valve rod, axle sleeve is stuck, increases executing agency's operational torque,
Keep valve switch not flexible.
Therefore, there is an urgent need to a kind of novel wear resistant separable type ball valves, process knife when processing the inner hole of lower valve rod of valve body
Tool can put in processing from body base, and cutter is short, and tool sharpening is easy to control, and the lower valve rod inner hole roughness processed is high；?
When work, pressure medium is not easy to cause valve seat deformation before valve, and torque is small, the long service life of ball valve；Between valve rod and axle sleeve not
It can block or stuck, executing agency's operational torque is small, and valve switch is flexible.
Summary of the invention
In order to overcome the shortcomings of existing research, the invention patent provides a kind of wear-resisting separable type fixing ball valve, is processing
When the inner hole of the lower valve rod of valve body, process tool can put in processing from body base, and cutter is short, and tool sharpening is easy to control, and add
The lower valve rod inner hole roughness that work goes out is high；At work, valve rod, axle sleeve will not block between valve body or stuck, executing agency behaviour
It is small to make torque, valve switch is flexible.
To realize that above-mentioned function, above-mentioned technical problem of the invention are mainly to be addressed by following technical proposals:
The invention discloses a kind of wear-resisting separable type fixing ball valves, which is characterized in that including executing agency, left valve barrel, the right side
Valve body, upper valve rod, lower valve rod, sphere, sphere are fixed by the upper valve rod and lower valve rod of its upper and lower axle heart line position, upper valve rod,
Disengaging is provided in the middle part of the valve inner that left valve barrel is arranged in sphere, lower valve rod, right valve barrel is composed, left valve barrel and right valve barrel
The channel middle of inlet and outlet is arranged in mouth channel, sphere, and left valve barrel, right valve barrel lower part are additionally provided with bracket, and internal stent is chamber
Body structure, lower valve rod lower part are arranged in the cavity body structure of bracket, and the bottom of the bracket is provided with bottom cover, the inner surface of bottom cover
Middle part is provided with mounting groove, and installation slot center is provided with steel-ball groove, and lower valve rod bottom centre is provided with steel ball, and steel ball is located at bottom cover
Steel-ball groove in, sliding bearing is installed between the mounting groove and lower valve rod bottom of bottom cover, lower valve rod top is provided with lower axle
It covers, is provided with lower packing seal in the middle part of lower valve rod.
Further, the sphere and left valve barrel, right valve barrel inlet and outlet are provided with valve component between channel.
Further, the lower packing seal includes lower stuffing-box, there is filler in lower stuffing-box, and filler bottom, which is provided with, to be filled out
Expect gland.
Lower valve rod lower part is arranged in the cavity body structure of bracket, and the lower valve rod that the top of lower valve rod is located at valve body is intracavitary, and
The lower valve rod cavity of valve body is just in the bottom of valve body, and when processing the lower valve rod inner cavity of valve body, cutter can directly put in valve body bottom
Portion's processing, and put in from bottom, it is only necessary to very short cutter, cutter is easy to control, thus the processing of the lower valve rod cavity of valve body
The roughness on surface can guarantee.
Pressure medium before valve, acts directly on lower valve rod, and lower valve rod is primarily located on sliding bearing, medium pressure before valve
Power is mainly born by sliding bearing, thus valve seat is not subject to excessive pressure, so the torque of wear-resisting separable type ball valve is small, valve
Seat deforms small, long service life.
When wear-resisting separable type ball valve works, when containing solid particle in medium, since lower valve rod bottom is provided with steel ball
And sliding bearing, friction is reduced, upper valve rod and lower valve rod flexibly rotate freely under executing agency's driving very much simultaneously, and leakage exists
Solid particle between axle sleeve and lower valve rod is just not easy to accumulate, and is just less prone between axle sleeve and lower valve rod and blocks phenomenon.
When valve in-vivo medium is under the condition of high temperature, sliding bearing is mounted on the mounting groove of the bottom cover outside valve body
Interior, far from medium, sliding bearing would not be increased with medium temperature and be increased, lower valve rod and axle sleeve, and sliding bearing would not be by
Occur stuck in high-temperature heat expansion effect.
Such lower valve rod, axle sleeve, sliding bearing will not block or stuck, alleviate executing agency's operational torque, make valve
It switchs more flexible.
Benefit of the invention:
1, a kind of wear-resisting separable type fixing ball valve of the invention, when processing the lower valve rod cavity of valve body, cutter is directly from valve body
Bottom feed, cutter is short, easily controllable, it is ensured that the roughness of valve body lower valve rod cavity.
2, a kind of wear-resisting separable type fixing ball valve of the invention, the torque of wear-resisting separable type ball valve is small, valve seat deformation is small, makes
It is long with the service life.
3, a kind of wear-resisting separable type fixing ball valve of the invention, lower valve rod, axle sleeve, sliding bearing will not block or stuck,
Executing agency's operational torque is alleviated, keeps valve switch more flexible.
