Description
Technical field
The utility model relates to valve technology field, particularly to one to folder butterfly valve.
Background technology
Current in folder butterfly valve, the intensity of valve own is low, and valve rod uses Double half axle attachment structure, and the Double half axle of valve rod leads to
Crossing taper bolt to connect, such structure easily causes fluid to leak because of pin poor sealing, and the stem structure of Double half axle is cut
The weak thickness of valve plate, as sharply increased because of water flow pressure, easily causes valve plate damaged.The existing valve stem seal to folder butterfly valve
Place uses copper sheathing, high score sub-set and rubber sleeve three process, and sealing effectiveness is also undesirable, easily causes leakage.In addition, it is existing
To folder butterfly valve at the scene when be difficult to install, installation effectiveness is low.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of easy install and good sealing effect right
Folder butterfly valve.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the utility model is achieved through the following technical solutions: one
Kind to folder butterfly valve, including valve body, valve seat, valve rod and valve plate, described valve seat is installed in valve body, described valve rod radially mounted in
In valve body, described valve seat has valve pocket, and described valve plate is installed on the bottom of described valve rod, and this valve plate is placed in described valve pocket,
Equipped with rubber seal on described valve seat, this rubber seal has draw-in groove, and rubber seal is arranged in described by this draw-in groove
On valve seat, described valve rod is axis structure, is provided with the upper sealing being set on this valve rod between the top of described valve rod and valve body
Circle, is provided with the pressure bearing being set on this valve rod, the bottom of described valve rod and valve body between the middle part of described valve rod and valve body
Between also be provided with the lower seal that is set on this valve rod, the upper side and lower side of described valve body is equipped with flange hole.
Further, described valve body and valve plate are provided with epoxy resin baking vanish layer.
Further, the top of described valve body is provided with worm wheel head, and the outside of this worm wheel head is provided with handwheel.
The beneficial effects of the utility model are: the body strength to folder butterfly valve of the present utility model is relatively big, and pressure-bearing is big, to respectively
The adaptability planting operating mode is higher.Rubber seal is arranged on valve seat by the draw-in groove on it, thus rubber seal be difficult to because of
Abrasion comes off, and it is more firm to seal, and is difficult to reveal.Valve rod in the utility model be axis without latch structure, not in use by Double half axle
Attachment structure, thus valve rod does not use taper bolt, can avoid the leakage causing because pin position nail system is bad, decrease valve
The leakage point of body, better tightness, also enhance valve rod intensity.It is provided with between the middle part of the valve rod in the utility model and valve body
Pressure bearing, seals the traditional copper sheathing of replacement, high score sub-set and rubber sleeve by using pressure bearing, reduces valve body switch and turn round
Square, is more favorable for the switch of valve, enters at valve rod if any liquid, and pressure bearing then can more be pressed tighter, and high decreases valve
The situation that bar leaks, improves sealing, and if butterfly valve have deterioration extent, spare and accessory parts can be changed at any time, it is not necessary to overall house
Abandon, have more economy.In addition, the upper side and lower side of valve body is equipped with flange hole, thus when mounted, can be by this flange
Hole is hung on bolt very easily, it is simple to singlehanded butterfly valve of installing, and the saving set-up time, improves installation effectiveness.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
As depicted in figs. 1 and 2, a kind of to folder butterfly valve, including valve body the 1st, valve seat the 2nd, valve rod 3 and valve plate 4, described valve seat 2 is pacified
Being loaded in valve body 1, described valve rod 3 is radially mounted in valve body 1, and described valve seat 2 has valve pocket 21, and described valve plate 4 is installed on
The bottom of described valve rod 3, and this valve plate 4 is placed in described valve pocket 21, equipped with rubber seal 5 on described valve seat 2, this rubber is close
Seal 5 has draw-in groove, and rubber seal 5 is arranged on described valve seat 2 by this draw-in groove, and described valve rod 3 is axis structure, described
Be provided with the upper sealing ring 6 being set on this valve rod 3 between the top of valve rod 3 and valve body 1, the middle part of described valve rod 3 and valve body 1 it
Between be provided with the pressure bearing 7 being set on this valve rod 3, also be provided with being set in this valve rod between the bottom of described valve rod 3 and valve body 1
Lower seal 8 on 3, the upper side and lower side of described valve body 1 is equipped with flange hole 101.
Furtherly, described valve body 1 and valve plate 4 are provided with epoxy resin baking vanish layer, can increase the cleanliness of fluid, more
Add environment protection health.
Furtherly, the top of described valve body 1 is provided with worm wheel head 9, and this worm wheel head 9 is connected with handwheel 10, by handwheel 10
