The process of interior movement is also to clean the process of valve pocket, and therefore, plunger type emptying valve can be applied to slurry process medium, for pipeline
Sampling and blowing, as long as plunger leaves runner completely, plunger valve can provide delivery working condition, and plunger type emptying valve is applicable
Major ingredient and the sampling of the reactor of agitator are carried in chemical industry, petrochemical plant, the sealing of plunger type emptying valve is above and below
Two sealing rings, jacket casing and stick harness composition, when stick harness fills in ring inner hole, by being applied to gland by gland nut
On load the sealing ring around plunger is compressed, so as to ensure that sealing, when valve opening extraction plunger, the material of sealing ring
Material answers reset condition next time in elastic reaction, in actual use, because plunger type emptying valve is generally used in reactor
Place, plunger head Reusability causes stick harness edge easily to wear and tear, so that the sealing effectiveness of plunger type emptying valve can be influenceed.
Utility model content
The purpose of this utility model is that there is provided a kind of preferable plunger type emptying valve of sealing for existing issue.
The utility model is achieved through the following technical solutions：A kind of preferable plunger type emptying valve of sealing, including
Valve body, the discharging opening that valve body includes the feeding mouth at top and set in side wall, discharging opening is outer to be connected with discharge pipe, feeding mouth pair
The lower section answered is movable chamber, and movable chamber bottom is provided with valve rod, and stem bottom is provided with outside handwheel, valve stem top installing stick harness, stick harness
It is provided with external screw thread week, movable cavity wall is provided with the internal thread one matched with stick harness external screw thread, provided with annular below feeding mouth
Platform, annular table inwall is provided with the internal thread two matched with stick harness external screw thread, and annular groove is provided with above annular table, and annular is recessed
Ring-shaped rubber pad is provided with groove；
Wherein, it is provided with the upside of annular groove in groove one, groove one and is provided with sensor one, groove is provided with movable chamber bottom
Two, groove two is interior to be provided with sensor two.
As further improvement of these options, the sensor one and sensor two gather information and are transferred to control
Center processed, is operated accordingly to the information collected.
As further improvement of these options, the handwheel is by control centre according to need of work and sensor one
It is controlled with the information of sensor two.
As further improvement of these options, control button is installed on the outside of valve body, for controlling handwheel to work.
The utility model has advantages below compared with prior art：The plunger type emptying valve operationally, makes stick harness upward
Screwed at the top of rotation, stick harness in the internal thread two of feeding mouth cavity wall, press to form sealing with ring-shaped rubber pad, press rear sensor
One receives information, controls stick harness to stop upward motion by control centre, even if stick harness top edge is worn and torn, still can be with
Sealed by ring-shaped rubber pad and the mode of spinning, when stick harness is moved downwardly to movable chamber bottom, stick harness bottom squeeze
Sensor two, sensor two will gather the incoming control centre of information, and control stick harness stops moving downward, and makes plunger type emptying valve real
Now automatic work, sealing effectiveness is strengthened, and remains to keep preferable sealing in the case of stick harness top edge on a small quantity abrasion, prolongs
Its long service life.
