Abstract

The utility model is mainly used in the open and close field of operated pneumatic valve gas outlet, more particularly to a kind of operated pneumatic valve slow closing device, including air inlet, the first gas outlet and the second gas outlet, also include Slow Close component, Slow Close component is arranged at the first gas outlet and the second gas outlet, Slow Close component includes the plug being engaged with the first gas outlet and the second gas outlet, plug inner hollow, the Slow Close bolt coordinated with hollow part is set on the outside of plug, and hollow part corresponds to Slow Close bolt and sets the internal thread being engaged.To open gas outlet during operated pneumatic valve, the second gas outlet is the gas outlet for closing operated pneumatic valve for first gas outlet.The utility model is simple and reasonable, easily realizes, removes muffler, saves cost.On the basis of pneumatic valve configurations are not changed so that the speed that pneumatic operated valve opens and closes can adjust, and eliminate the problem of producing water hammer when pneumatic operated valve is applied in feedwater piping, ensure the safety of feedwater piping.

Description

Operated pneumatic valve slow closing device
Technical field
A kind of operated pneumatic valve slow closing device is the utility model is related to, is mainly used in unlatching and the pass of operated pneumatic valve gas outlet Closed neighborhood.
Background technology
For pneumatic operated valve to be entered by gases at high pressure in pneumatic operated valve cylinder, driving flap motion carrys out the opening and closing shape of control valve State, there are an air inlet, a unlatching gas outlet and a closing gas outlet, using the open and-shut mode of pressure control valve, and Only be mounted with muffler at two gas outlets of present situation, gases at high pressure are quickly discharged, cause pneumatic operated valve opening and closing speed compared with It hurry up.In the application of water industry, quickly open and close, easily produce water hammer, cause the vibrations of pipeline, to the safety of pipeline Stable operation causes greatly to damage.
Utility model content
The technical problems to be solved in the utility model is:Offer one kind, which can be eliminated when pneumatic operated valve is applied in feedwater piping, produces The problem of unboiled water is hammered into shape, and the operated pneumatic valve slow closing device of feedwater piping safety can be ensured.
Operated pneumatic valve slow closing device described in the utility model, including air inlet, the first gas outlet and the second gas outlet, also Including Slow Close component, Slow Close component is arranged at the first gas outlet and the second gas outlet, and Slow Close component includes and the first gas outlet The plug being engaged with the second gas outlet, plug inner hollow, plug outside set the Slow Close bolt coordinated with hollow part, in Empty position corresponds to Slow Close bolt and sets the internal thread being engaged.Gas outlet when first gas outlet is unlatching operated pneumatic valve, second Gas outlet is the gas outlet for closing operated pneumatic valve.
Described plug includes the cylindrical section of bottom and the annulus section at top, and cylindrical section and annulus section composition radial section are The plug of T-shaped.
The hollow space of described cylindrical section is identical with annulus section lumen portion internal diameter.
The utility model proposes the muffler dismounting of the exit installation of pneumatic operated valve, installation can adjust air bleeding valve, passed through Adjustment to can adjust exhaust valve opening, the speed that control pneumatic operated valve opens and closes.
In use, it is located at the depth of hollow part according to the good Slow Close bolt of diameter and length adjustment of pipeline in advance, and then Adjust the speed that pneumatic operated valve opens and closes.
The beneficial effects of the utility model are:
It is simple and reasonable, easily realize, remove muffler, save cost.On the basis of pneumatic valve configurations are not changed, So that the speed that pneumatic operated valve opens and closes can adjust, eliminate and asked in pneumatic operated valve in feedwater piping using caused water hammer Topic, ensure the safety of feedwater piping.
