Background technology
Gate valve can make valve rod drive linear motion above and below flashboard realization by rotation hand wheel, realize the function of opening and closing, tradition
All it is to use taper sealing between the valve body and flashboard of gate valve, therefore when gate valve is opened to maximum, flashboard can be on valve body
Chamber, can have excessive gap between valve body and flashboard, cross the presence of wide arc gap and flashboard is occurred with the rotation of valve rod
Rotation, the linear motion not moved up and down, when turning moment is slightly larger, the sealing margin of the flashboard of rotation will
Damaged by the sealing margin of valve body, when serious, flashboard jam can be caused in valve body epicoele, it is impossible to which playback is complete to valve body folding intracavitary
It into closed action, can not be sealed between valve body and flashboard, it may occur that leakage accident, there is serious potential safety hazard.
The content of the invention
The technical problem that the utility model will solve condition is to provide a kind of Novel Brake Valve, and it can be opened in gate valve to maximum
When flashboard is not rotated with the rotation of valve rod, it is ensured that flashboard and valve body are not in the feelings that sealing margin is damaged
Condition, it is ensured that sealing between the two, can more prevent leakage hidden trouble.
The technical scheme in the invention for solving the above technical problem is：
The utility model discloses a kind of Novel Brake Valve, including valve body, the bonnet above valve body and in valve body
Folding chamber, folding intracavitary is provided with the flashboard that matches with it, and flashboard is connected with valve rod, and valve rod one end sequentially passes through valve body, valve
Cover and be connected with handwheel, it is characterised in that：The bonnet inwall both sides are provided with mutually symmetrical locating slot；The flashboard upper end two
Side is provided with the alignment pin corresponding with positioning groove location；The bonnet upper end is provided with a firm groove；The firm groove is under-filled
There is filler, top is provided with a trim ring, and trim ring is pressed on filler；The filler is all sheathed on outside valve rod with trim ring；The bonnet
Upper end is bolted with pressure cap, and pressure cap inwall presses on trim ring.
The bonnet inwall is provided with a stopper slot；The valve rod is externally provided with a spacing ring being located in stopper slot；The limit
A collar is provided with below the groove of position；Spacing ring is stuck in stopper slot by the collar；The collar is in circular platform type.
It is axial seal between the valve body and bonnet；The lower surface that the bonnet is in contact with valve body upper surface is provided with
One seal groove；The sealing ring matched with it is installed in the seal groove.
The beneficial effects of the utility model are：
Compared with prior art, being sticked in locating slot by alignment pin using the Novel Brake Valve of the utility model structure can
The rotation of flashboard is limited, when making gate valve unlatching to maximum, the sealing margin of flashboard will not be damaged by the sealing margin of valve body, make lock
Plate smooth can return to folding intracavitary when gate valve is closed and complete closed action, make flashboard have more stable sealing property,
And prevented the leakage hidden trouble of presence, it is ensured that security when gate valve is used.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model Novel Brake Valve；
Fig. 2 is the structural representation of the different angles of bonnet two；
Fig. 3 is that alignment pin slips into structural representation when in locating slot.
Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 to Fig. 3 is referred to, the utility model provides a kind of Novel Brake Valve, including valve body 1, the valve located at the top of valve body 1
Provided with the flashboard 4 matched with it in lid 2 and the folding chamber 3 in valve body 1, folding chamber 3, flashboard 4 is connected with valve rod 5,
The one end of valve rod 5 sequentially passes through valve body 1, bonnet 2 and is connected with handwheel 6, and the inwall both sides of bonnet 2 are provided with mutually symmetrical positioning
Groove 7；The upper end both sides of flashboard 4 are provided with the alignment pin 8 corresponding with the position of locating slot 7；The upper end of bonnet 2 is consolidated provided with one
Groove 9；The firm groove 9 is under-filled filler 10, and top is provided with a trim ring 11, and trim ring 11 is pressed on filler 10；It is described to fill out
Material 10 is all sheathed on outside valve rod 5 with trim ring 11；The upper end of bonnet 2 is bolted with pressure cap 12, and the inwall of pressure cap 12 presses in trim ring 11
On.
The inwall of bonnet 2 is provided with a stopper slot 13；The valve rod 5 is externally provided with a spacing ring being located in stopper slot 13
14；The lower section of stopper slot 13 is provided with a collar 15；Spacing ring 14 is stuck in stopper slot 13 by the collar 15；The collar 15
In circular platform type.
It is axial seal between the valve body 1 and bonnet 2；On the lower surface that the bonnet 2 is in contact with the upper surface of valve body 1
Provided with a seal groove 16；The sealing ring 17 matched with it is installed in the seal groove 16.
Application method of the present utility model is as follows：During gate valve is opened to maximum, valve can be made by turn handwheel 6
Bar 5 drives flashboard 4 gradually constantly to be moved towards the epicoele of valve body 1, and folding chamber 3 is started to open at, and flashboard 4 now does upward straight line
Motion, therefore the lateral attitude of the alignment pin 8 on flashboard 4 is constant all the time, it is corresponding with the position of locating slot 7 all the time, when fixed
