Technical field
The utility model relates to a kind of ball valve more particularly to a kind of Fixed ball valves.
Background technique
Since idea and technology of the past to valve maintenance maintenance lack, many users are also being used " died and mended jail again "
Extensive management pattern.Valve is in the case where no progress time-based maintenance maintenance, once a leak occurs, illustrate that damage is very serious,
It is possible that having lost the possibility and value of maintenance.In addition, repairing after failure originally is a kind of passive situation, security risk at this time
It has resulted in, loss has occurred, and the service life of the safe handling and valve to a complete set of equipment is all totally unfavorable.However, risk
Be not it is uncontrollable, preventative maintenance is crucial.Valve is inspected periodically, when first time discovery valve has leakage, immediately
It is repaired, is stopped loss in time.Because even being in the case where atomic small sealing surface corrupted, the medium of circulation also can be extremely short
Time in cause the large area corrupted of sealing surface so that causing the maintenance cost and operations risks of later period valuableness.Therefore, for
It is the meaning for wanting training personnel inspect periodically, rigorously safeguard, being preventive from possible trouble for the organization and management person of valve application
Know, and awards with the maintenance methods of science.It periodically, scrupulously overhauls and maintains in the method for science, be to solve valve leak
With prolong the service life in most economical and reliable approach.Root Ju American Society of Mechanical Engineers (ASME) is to air shooter line
- 1992192.745 Federal Specification of guidance, the gas transmission line valve of each emergency and point defeated system valve for safe operation
Must test and part operation in being no more than interval 15 months, and it is annual at least once；And to the pre- of valve
Anti- property maintenance, for example before the arrival of cold season section, the blowdown valve of ball valve need to be opened, the condensation in purging line (ball valve cavity)
Water.Increase the torque of valve to prevent valve internal from freezing；The opening of the blowdown valve of existing ball valve needs to reverse bolt；Take
When it is laborious, be badly in need of a kind of opening convenient blowdown valve on the market now.
Utility model content
The utility model lies in that providing, a kind of structure is simple, a kind of Fixed ball valve of personnel's operation convenient for safeguarding.
In view of the above problems, providing following technical solution: a kind of Fixed ball valve, including valve body and pass through with valve body
Valve deck that screw is tightly connected, positioned at the intracorporal sphere of valve, the valve rod that connects sphere and handwheel for adjusting sphere, be used for
The valve seat of sealing；It is characterized by: being provided with the blowdown valve of connection valve inner below the valve body；The blowdown valve includes one
A pipeline being connected to valve body and button effluent switch with the end adapter of pipeline；The inner wall of the end of the pipeline is arranged

The utility model has the beneficial effects that being checked in service personnel, maintenance is protected after the utility model is mounted on conveyance conduit
When supporting, need to open the blowdown valve of ball valve, the condensed water in purging line (ball valve cavity).With prevent valve internal freeze and
Increase the torque of valve；And in the gap between sphere and valve body, because the rotation of the sphere of the rotate driving of handwheel can be led
Cause that there is the liquid (such as water) penetrated into gap, such water can corrode in valve body in immobilising situation for a long time
Portion influences its service life, needs for it to be timely discharged, and general blowdown valve is when opening, and the sewage that ejects is easy
It splashes winged, makes the clothes of service personnel dirty, and the structure setting of the blowdown valve of the utility model, service personnel are discharged in button press
After switch, cause spring that elastic deformation, the inner wall disengaging of sealed disc and first annular boss occurs；Form one and the external world
The channel of connection, sewage flow through the pipeline of blowdown valve, then pass through the second annular convex platform inner wall, then pass through going out on stop collar
Water hole, but because of the limitation of nut cap bottom, water flow forms the radian of a u font, outflow direction and finger direction
On the contrary, to achieve the effect that prevent splashing；And the blowdown valve arrangement of the utility model is simple, convenient for promoting.
