Description
Technical field
This utility model is related to valve technology field and in particular to a kind of pneumatic cut-off reversal valve.
Background technology
Traditional pneumatic cut-off reversal valve such as patent No.: 201320654988.4 denomination of invention hand-operated pneumatic cut-off reversal valves
The existing stop valve mentioned includes valve seat and valve body at different levels, and valve body is provided with charging aperture and discharging opening, and the valve rod in valve seat is worn
Cross each valve body, valve rod is provided with the flap mating with valve body entrance end, rely on the movement of valve rod driving flap to block or
Open the port of valve body, with this, charging aperture and the connection of different discharging openings are realized the purpose of commutation, existing pneumatic cut-off is changed
To valve when valve opens or closes, drive flap by driving valve rod, the resistance now overcoming required for operating physical force, is medium
Flowing and flap are conflicted the resistance producing, and why pneumatic cut-off reversal valve is very suitable for the occasion of some low discharges, is
Because when flow is big, entrance end is bigger with flap respective design, and medium is increased with valve flap contacts area, produced resistance
Also accordingly increase, make flap movement become difficult, cause to drive the action required power of valve rod flap to increase therewith, so that flap is moved
Speed is obstructed, and when flow is excessive, flap surface is impacted so that valve rod is susceptible to the danger of bending.
Content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide one kind when flap moves, and can subtract

4. specific embodiment of the present utility model as shown in figures 1 to 6, a kind of pneumatic cut-off reversal valve of fast conducting,
Including valve seat 1, upper valve body 2 and lower valve body 3, described upper valve body 2 and lower valve body 3 side be respectively provided with liquid medium flow into or
The charging aperture 21 flowing out and discharging opening 22, described valve seat 1, upper valve body 2 and lower valve 3 body are accepted and mutual conduction successively, described
It is provided through upper valve body 2 valve rod 4 extending in lower valve body 3, described valve rod 4 is located on the one end in lower valve body 3 in valve seat 1
It is provided with the flap 5 of closing discharging opening 22, this flap 5 is front towards one end of valve seat 1, and flap 5 is anti-away from a section of valve seat 1
Face, described valve rod 4 other end extend to valve seat 1 outer and be provided with the Pneumatic assembly 6 driving valve rod 4 movement it is characterised in that: described
Flap 5 be provided with first filter opening 7 in UNICOM's flap 5 front and reverse side two ends, this flap 5 is provided with control the first filter opening 7
Conducting filter opening locking device 8, described filter opening locking device 8 include the rotation flap 81 corresponding with the first filter opening position and
Control the lockable mechanism 82 of rotation flap rotation.
When needing operating valve lever 4 mobile, when flap 5 is closed or opened certain side discharging opening 22, operation filter opening first is closed
Device 8 opens or closes the first filter opening 7, that is, pass through lockable mechanism 82 and control rotation flap 81 to rotate, close the first filter opening 7 port
Rotation flap 81 be subjected to displacement, the first filter opening 7 is opened or closes, and when the first filter opening 7 is opened, medium just can be by the
One filter opening 7 passes through flap 5 and rotation flap 81, decreases the resistance that medium produces when mobile to flap 5, and improves flap 5
The speed of folding, it is to avoid the danger that valve rod 4 is bent, when valve rod 4 movement finishes, operation rotation flap 81 rotates, the first filter
Hole 7 port is rotated flap 81 and is blocked, and medium is intercepted by flap 5 and rotation flap 81, completes the commutation of discharging opening 22.
Described rotation flap 81 is sheathed on valve rod 4 periphery and presses located at flap 5 towards on the end face of valve seat 1, this rotation
Flap 81 is fixedly installed sleeve pipe 83 with valve rod 4 rotatable engagement towards one end of valve seat 1, corresponding the on described rotation flap 81
It is provided through on the position of one filter opening 7 rotating the second filter opening 84 of flap 81.
Rotation flap 81 is made to pass through sleeve pipe and valve rod 4 rotatable engagement, that is, sleeve pipe 83 is sheathed on valve rod 4 outer peripheral face it is not necessary to another
If connecting the valve rod 4 of rotation flap 81, save the space in valve body, and it is corresponding with the first filter opening 7 seat to pass through setting
Second filter opening 84, when operation rotation flap 81 opens the first filter opening, only needs the first filter opening 7 and the second filter opening alignment 84, medium is just
Flap 5 and rotation flap 81 can be passed through by the first filter opening 7 and the second filter opening 84, when valve rod 4 movement finishes, operation rotation flap
81 rotations, the first filter opening 7 is staggered with the second filter opening 84, and medium is intercepted by flap 5 and rotation flap 81, completes changing of discharging opening 22
To so setting operation rotates during flap 81 it is only necessary to the appropriate angle of rotation, just can complete to operate, the anglec of rotation is little, operation
Speed is fast.
Described sleeve pipe 83 inwall is provided with annular lug 85, and described valve rod 4 is to should the position of annular lug 85 be provided with
Annular groove 41 with annular lug 85 rotatable engagement.
Engaged with annular groove 41 by annular lug 85, make the rotatable engagement that sleeve pipe 83 can keep with valve rod 4, and energy
Move axially with valve rod 4 and together lift, eliminate and separately set the drive mechanism driving rotation flap 81 axial movement.
Described flap 5 is provided with cavity 51 towards one end of valve seat 1, and described rotation flap 81 supports away from one end of valve seat 1
In cavity 51, the opening of this cavity 51 is less than the diameter of discharging opening 22, and cavity 51 medial wall is provided with cannelure 52, should
It is provided with the sealing ring 53 making rotation flap 81 and cavity 51 sealing in cannelure 52.
By being arranged at rotation flap 81 in the cavity 51 on flap 5, and the opening of flap 5 cavity 51 is less than discharging
Mouthfuls 22 diameter, make flap 5 close discharging opening 22 towards valve seat 1 one end mobile when, conflict sealing with discharging opening 22 is valve
When lobe 5 end face, rather than rotation flap 81, the so rotation of operation rotation flap 81, would not be because of rotation flap 81 and discharging opening
22 end faces pressings lead to not situation about rotating, and in cavity 51 cannelure 52 setting sealing ring 53 it is therefore prevented that the first filter opening 7
When staggering with the second filter opening 84, medium leaks into the danger of reverse side from flap 5 front.
Described lockable mechanism 82 includes the handwheel 9 with sleeve pipe 83 linkage, the lock pin 91 of lock collar 83, described set
Pipe 83 is linked with handwheel 9 away from one end of cavity 51, and sleeve pipe 83 and valve rod 4 are provided with locking hole 92, described locking
Pin 91 extends in valve rod 4 locking hole 92 through sleeve pipe 83.
Lock pin 91 extends in valve rod 4 locking hole 92 through sleeve pipe 83, so that sleeve pipe 83 is rotated when finishing and passes through lock pin
91 are locked, and prevent unintentional rotation, and pass through to arrange handwheel 9, and simple operationss just can drive sleeve 83 rotate.
The first described filter opening 7 away from valve seat 1 one end with diameter greater than the diameter towards valve seat 1 one end, tapered poroid.
Using such scheme, when the direction that flap 5 is directed away from valve seat 1 is mobile, medium passes through the first filter opening 7 diameter relatively
Big one end enters, and can circulate faster.
The second described filter opening 84 towards valve seat 1 one end with diameter greater than the diameter away from valve seat 1 one end, tapered hole
Shape.
When flap 5 moves towards the direction of close valve seat 1, medium is entered by one end that the second filter opening 84 is relatively large in diameter
Enter, can circulate faster.
