Description
Technical field
The present invention relates to the shut-off mechanism of pressure regulator technical field, more particularly to pressure regulator.
Background technology
When the shut-off mechanism of pressure regulator refers to that controlled pressure exceedes arranges value, sprue inlet flow can be automatically cut off
A kind of valve of body, existing pressure regulator typically without tripping protection, are also easy to produce accident in some specific occasions；Even if there is band at present
The pressure regulator of tripping protection, there is also the defects such as general structure is complicated, packaging technology is loaded down with trivial details, sensitivity is poor, so causes to make
With trouble, the counter productives such as inconvenience are operated.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of simple structure, it is easy to use can automatic or manual cut-out and
The shut-off mechanism of the pressure regulator of hand-reset.
Realize that technical scheme is as follows：
The shut-off mechanism of pressure regulator, including shell, diaphragm cavity shell, and be arranged in diaphragm cavity shell and be classified as
The balance film of upper and lower two cavitys, upper cavity are provided with and connect gas port, are provided with the pallet contacted with balance film in cavity of resorption body, pallet with
Connecting rod connects, and the connecting rod be connected with the shut-off mechanism for being arranged on inside the shell, shut-off mechanism include by the first spring and
The swingle of shell vertical connection, and the first swing arm, the second swing arm and the rocking bar being flexibly connected with shell, swingle are provided with
The contact of connection, first swing arm are arranged on the lower section of swingle, and the head of the first swing arm is connected with housing into rotation, afterbody with
Swingle is meshed, and the first swing arm is provided with the first groove being adapted with the second swing arm afterbody, and the first groove is for by second
The stuck positioning of swing arm, the middle part of the second swing arm are connected with housing into rotation, and the head of the second swing arm is provided with and is adapted with rocking bar head
The second groove, rocking bar afterbody and shell rotate and be connected, and rocking bar makes its head just can realize to the second groove by rotating
The function of locked positioning, the rocking bar are connected with reseting handle.
Above-mentioned scheme is employed, the cut-out mode of the present invention includes automatically cutting off and hand off, in diaphragm cavity shell
Air pressure in cavity is adjusted by balance film, and when air pressure is too high, pallet will be moved down, and swingle be made by the effect of connecting rod
Rotate, now the first swing arm departs from swingle and rotates clockwise, the second swing arm afterbody is discharged from the first groove and counterclockwise
Rotate, so that rocking bar head departs from the second groove and rotates clockwise that (rocking bar is connected with valve rod, and the rotation of rocking bar can drive valve
The movement of bar, such that it is able to realize folding of the valve rod to valve block), now valve port is blocked closing by valve rod, you can blocking gas enters
Enter, this mode is to automatically cut off；It can in addition contain by button touch contact rotate swingle, working method ibid, equally
Gas entrance can be blocked；When needing that air inlet opens valve port again, only need to by pulling reset spanner, make rocking bar, second
Swing arm, the first swing arm and swingle return to initial position, simple structure, using conveniently, safely.
First swing arm, the second swing arm are connected by wheel shaft with shell, and advantage is that wheel shaft flexibility is high, rotating property
It is good, can effectively drive the first swing arm and the second swing arm to rotate around it.
The wheel shaft of first swing arm is provided with fix bar, and helical spring, the head of the first swing arm are arranged with fix bar
The gag lever post parallel with fix bar is provided with, one end of helical spring is inconsistent with shell, and the other end is inconsistent with gag lever post, excellent
Point is that the afterbody of the first swing arm can firmly bite swingle by the effect of second spring, while the first groove can also be made
Tightly block the second swing arm, prevent its slip from coming off.
Housing is provided with can be corresponding with contact with the button of hand off, button, realizes rotation by making contact displacement
The function that bar rotates to realize shearing device disconnection, advantage is by button press, you can promote contact, contact that bar is rotated
Rotation, makes the afterbody of the first swing arm depart from swingle, realizes that then disconnection is acted on.
It is connected with below the connecting rod with the pneumatic coupling mechanism to swingle positioning function, advantage is easy for diaphragm
Acted directly in pneumatic connection system by connecting rod after air pressure balance failure in chamber, so as to realize function of automatically cutting off.

It is also associated with upper guide bush with the keeper for blocking swingle；Protection device includes the upper guide bearing being set in connecting rod
And the lower guide bearing being connected by the 3rd spring with upper guide bearing, the lower guide pin bushing and lower guide bearing are fixture, excellent
Point is that, when in diaphragm chamber, air pressure is excessive, pallet pushes connecting rod, and connecting rod promotes upper guide bearing to make which move down, above leads
Contacted with upper guide bush to bearing again and which is also moved down, be positioned such that part departs from swingle, that is, lost the positioning to swingle and make
With swingle is rotated and reaches the effect for automatically cutting off；When needing to recover, manually adjusting reseting handle can make swingle
Original position is returned to, now keeper is positioned to swingle again, simple structure is easy to use, upper guide bearing is led with above
There is a fixed gap between set, in order which has one section of cushion space, can thus adjust the air pressure range in diaphragm chamber, have
It is compared beneficial to which in big scope and works.
The swingle is provided with the locating slot being engaged with keeper.
The side of first swing arm and the second swing arm is designed with position-limitting pin, advantage be position-limitting pin to the first swing arm and
Second swing arm carries out spacing, prevents its rotation amplitude excessive so as to act on failure.
