Description
Technical field
The utility model relates to blow-off valve technical field more particularly to a kind of self-locking piston high-temperature blow-off valves of band.
Background technique
In the technique that greasy filth, waste plastic catalytic pyrolysis generate fuel oil, the breeze finally generated is discharged under high temperature,
This just puts forward higher requirements residual cake valve, and former residual cake valve is using screw-type hand-operated valve.The valve closed tight at normal temperature exists
When high temperature is opened, since screw rod heat expansion extends, valve is stubbornly refused easily to open by swollen；When closing valve, due to having metal in breeze
The foreign matters such as silk, which can often block valve, makes valve be not closed completely.This residual cake valve is not easy to grasp and make heavy workload, influences work effect
Rate, while there is also security risks.In view of this, therefore proposing the application.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of self-locking piston high-temperature discharges of band
Valve, effect are good.
The utility model proposes a kind of self-locking piston high-temperature blow-off valve of band, including valve housing, valve cylinder, valve plug, mandril,
Pressing plate, compression spring, connector, master cylinder, lock pin, countercylinder, limit switch, valve are put on equipped with through-hole, discharge gate outside；Valve cylinder
It is slidably connected in valve housing and with valve housing, valve cylinder is equipped with holding tank for closing or opening discharge gate, valve cylinder；Valve plug
In holding tank；Pressing plate is located at valve cylinder close to the side of holding tank, and pressing plate is connect with valve cylinder；Mandril is located in valve housing, top
One end of bar passes through pressing plate and connect with valve plug, and mandril is slidably connected with pressing plate；Connector and mandril are connected far from one end of valve plug；
One end of compression spring is connect with pressing plate, and the other end is connect with connector；Master cylinder and connector are sequentially connected；Lock pin and through-hole
It matches；Countercylinder is used for band pendulum lock pin and passes in and out through-hole；Limit switch is used to detect the position of lock pin.
It preferably, further include the first thermal insulation board, the first thermal insulation board is located in valve housing, and the first thermal insulation board is located at pressing plate and valve
Between cylinder, and it is connect respectively with pressing plate, valve cylinder.
It preferably, further include the second thermal insulation board, the second thermal insulation board is located in valve housing, and the second thermal insulation board is leaned on positioned at connector
The side of nearly mandril, the second thermal insulation board are connect with connector.
In the utility model, cutting off the foreign matters such as wire using piston type closing mode ensures that closing is tight reliable；It utilizes
Compression spring tension and lock pin realization keep constant pressure and act on valve plug, to closed state pair when solving heat expansion and running out of steam
It influences.Automation control is realized using air pressure or Hydraulic Elements, limit switch, reaches raising working efficiency, it is hidden to eliminate safety
The purpose of trouble.
Detailed description of the invention
Fig. 1 is structural schematic diagram when the utility model is opened；
Fig. 2 is structural schematic diagram when the utility model is closed.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutual combination；Below with reference to the accompanying drawings it and in conjunction with the embodiments elaborates to the utility model.
Referring to Fig.1,2, the utility model proposes a kind of self-locking piston high-temperature blow-off valve of band, including valve housing 1, valve cylinder
2, valve plug 3, mandril 4, pressing plate 5, compression spring 6, connector 7, master cylinder 8, lock pin 9, countercylinder 10, limit switch 11, outside valve
It puts on and is equipped with through-hole, discharge gate 12；Valve cylinder is located in valve housing and is slidably connected with valve housing, and valve cylinder is used to close or the row of opening
Material mouth, valve cylinder are equipped with holding tank；Valve plug is located in holding tank；Pressing plate is located at valve cylinder close to the side of holding tank, pressing plate and valve
Cylinder connection；Mandril is located in valve housing, and one end of mandril passes through pressing plate and connect with valve plug, and mandril is slidably connected with pressing plate；Connection
Part and mandril are connected far from one end of valve plug；One end of compression spring is connect with pressing plate, and the other end is connect with connector；Master cylinder
It is sequentially connected with connector；Lock pin is matched with through-hole；Countercylinder is used for band pendulum lock pin and passes in and out through-hole；Limit switch is for detecting
The position of lock pin.
It further include the first thermal insulation board 13 in further embodiment, the first thermal insulation board is located in valve housing, and first is heat-insulated
Plate is connect between pressing plate and valve cylinder, and respectively with pressing plate, valve cylinder.Improve heat insulation.
It further include the second thermal insulation board 14 in further embodiment, the second thermal insulation board is located in valve housing, and second is heat-insulated
Plate is located at connector close to the side of mandril, and the second thermal insulation board is connect with connector.Improve heat insulation.
When closing valve, the outside that lock pin is located at valve housing is detected by limit switch first, master cylinder pushes connector
It is moved to the left, drives valve cylinder mobile by mandril, pressing plate, so that valve cylinder is moved ahead and material is cut off from discharge gate discharge by discharge gate.
Through-hole is passed through using countercylinder band pendulum lock pin simultaneously and enters valve housing, and at this moment the power of master cylinder disconnects, compression spring release
Tension force effect makes the contact surface between valve plug and valve cylinder keep a relative constant pressure between valve plug and connector；It completes
Valve is closed.By increasing lock pin, avoid after the pressure release of master cylinder, valve cylinder, connector surprisingly move to the right.
When valve is opened, master cylinder pushes connector to the left, then, is detached from valve housing using countercylinder band pendulum lock pin.?
It allows each component to playback, completes valve and open.
