Description
Technical field
The utility model relates to valve technology fields, and in particular to a kind of manual ball valve.
Background technique
Ball valve is the valve that opening and closing element (sphere) is driven by valve rod, and rotated around the axis of valve rod.It is mainly used for
Medium in truncation or connection pipeline, also can be used for the adjusting and control of fluid.Difference of the ball valve according to driving method, Ke Yifen
Are as follows: pneumatic ball valve, electrical ball valve and manual ball valve.
Wherein, pneumatic ball valve and electrical ball valve have the advantages that easy to use and high degree of automation, but there is also valences
The relatively high disadvantage of lattice, therefore pneumatic ball valve and electrical ball valve are generally all applied to fluid or gas medium flow control essence
The more demanding place of exactness, and manual ball valve is widely used in industrial production and daily life because its price is relatively low
Detachable collar domain.Manual ball valve in the prior art generally comprises main valve body, the auxiliary valve body connecting with main valve body, is set in main valve body
Spherical valve core, with the valve rod of spherical valve core clamping and handle for rotation valve rod.In the actual use process, we
It was found that the decreased food due to manual ball valve is longer, in use if the length direction in the direction of handle rotation and water pipe
When perpendicular or shape has a certain degree, outwardly projecting handle will be highly susceptible to the collision of the user of dealing,
Thus it not only will affect the rotation direction of handle and lead to the change of fluid circulation in valve, if when collision dynamics is larger also
Will lead to the injured handle simultaneously of user also will receive damage；Meanwhile if by the handle design length of manual ball valve at shorter
Although collision can be reduced to a certain extent, the torque that length reduces back handle can also be reduced therewith, at this time when in pipeline
Pressure it is larger when then may require that very big strength uses twisting handle, to increase the use difficulty of manual ball valve.
In view of the above-mentioned problems, being 201720502934.4 in number of patent application, patent name is a kind of operation of manual ball valve
Mechanism, authorized announcement date wrap to disclose a kind of manual ball valve operating mechanism in the Chinese utility model patent of 2018.03.06
The connector for being sleeved on ball-valve valve rod upper end is included, is fixed with sleeve on the connector；It further include that may pass through casing to pull company
The control stick of fitting and valve rod rotation, is arranged with the axis body that can be extracted out outward in described sleeve pipe, axis body is by passing radially through casing
It is fixed with the spacer pin of axis body, spacer pin one end is equipped with lock ring, and the other end offers lockhole and lockked by lockset；The behaviour
Vertical pole is articulated on the lock ring.The manual ball valve operating mechanism is by increasing rotating torque, to reach switch valve labour-saving mesh
, it is easy to use；It is reliable and stable, while can be avoided irrelevant personnel and arbitrarily changing valve state, it is highly-safe.For daily life
For manually-operated gate used in place living, although the operating mechanism of manual ball valve disclosed in the patent can be avoided handle mistake
It is collided caused by long evagination, but its use process is comparatively cumbersome, is unable to satisfy the demand of people.
