Abstract
The utility model discloses a soft seal gate valve, including valve body, valve rod and valve plate, the valve body has a valve pocket, the valve plate set up in in the valve pocket of valve body, the valve gap is installed on the upper portion of valve body, and the valve rod passes valve gap and valve body in proper order, and the lower extreme and the valve plate of valve rod are connected, is equipped with between the upper portion of valve rod and the valve gap and prevents leaking the subassembly, prevents leaking the subassembly and includes brass billet and rubber ring, and the brass billet suit is on the valve rod, and the rubber ring wraps up on the outside of brass billet, prevents that the top of leaking the subassembly is equipped with the gland, is equipped with O shape circle between gland and the valve rod, still is equipped with on the valve rod to be located the sealing ring of preventing leaking the subassembly below. The utility model discloses can reduce the friction between valve rod and the valve gap to prevent that the valve rod from receiving the friction and the emergence of the condition of revealing that causes, strengthened the sealing performance of valve rod, prolonged the life of valve rod and whole gate valve, can be applicable to various operating modes.
Description
Technical field
This utility model relates to valve technology field, particularly to a kind of soft sealing gate valve.
Background technology
Existing soft sealing gate valve sealing property is not ideal enough.Along with the on-off times of gate valve constantly increases, valve rod
And the friction between valve gap causes the damage of valve rod, and then causes whole gate valve easily to be revealed at valve rod, lock
The valve plate of valve fits badly so that the sealing property of whole gate valve does not reaches requirement, reduces the service life of gate valve.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of valve rod to be difficult to reveal, close
The envelope preferable soft sealing gate valve of effect.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is real by the following technical programs
Existing: a kind of soft sealing gate valve, including valve body, valve rod and valve plate, described valve body has valve pocket, described valve plate
Being arranged in the valve pocket of described valve body, the top of described valve body is provided with valve gap, and described valve rod sequentially passes through valve
Lid and valve body, the lower end of described valve rod is connected with valve plate, is provided with between top and the described valve gap of described valve rod
Spill-proof assembly, this spill-proof assembly includes brass billet and rubber ring, and this brass billet is set on described valve rod,
This rubber ring is wrapped on the outside of described brass billet, and being arranged over of described spill-proof assembly is sleeved on described
Gland on valve rod, is provided with multiple O, described valve rod is additionally provided with between described gland and described valve rod
It is positioned at the sealing ring below described spill-proof assembly.
Further, described valve body and valve plate are provided with epoxy resin baking vanish layer.
Further, the upper end of described valve rod connects handwheel.
The beneficial effects of the utility model are: be provided with anti-leak group between valve rod and the valve gap in this utility model
Part, spill-proof assembly includes brass billet and rubber ring, and brass billet is set on valve rod, and rubber ring is wrapped in Huang
On the outside of copper ring, thus by brass billet and the combination of rubber ring, it is possible to reduce between valve rod and valve gap
Friction, thus occurring of the leak case preventing valve rod from being rubbed and causing, enhance the sealing of valve rod
Can, extend valve rod and the service life of whole gate valve, go for various operating mode.It addition, on valve rod
It is additionally provided with the sealing ring being positioned at below spill-proof assembly, not only increases sealing property, and promote at valve plate
Under state, this sealing ring can be changed very easily, strengthen the serviceability of this gate valve.
Accompanying drawing explanation
Fig. 1 is structural representation 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 this utility model
Advantage and feature can be easier to be readily appreciated by one skilled in the art, thus to protection domain of the present utility model
Make apparent clear and definite defining.
As it is shown in figure 1, a kind of soft sealing gate valve, including valve body 1, valve rod 2 and valve plate 3, described valve body 1
Having valve pocket 101, described valve plate 3 is arranged in the valve pocket 101 of described valve body 1, the top of described valve body 1
Being provided with valve gap 4, described valve rod 2 sequentially passes through valve gap 4 and valve body 1, the lower end of described valve rod 2 and valve plate
3 connect, and are provided with spill-proof assembly, this spill-proof assembly bag between top and the described valve gap 4 of described valve rod 2
Including brass billet 5 and rubber ring 6, this brass billet 5 is set on described valve rod 2, and this rubber ring 6 is wrapped in institute
State on the outside of brass billet 5, the gland 7 being arranged over being sleeved on described valve rod 2 of described spill-proof assembly,
It is provided with multiple O 8 between described gland 7 and described valve rod 2, described valve rod 2 is additionally provided with described in being positioned at
Sealing ring 9 below spill-proof assembly.
Furtherly, described valve body 1 and valve plate 3 are provided with epoxy resin baking vanish layer, can increase fluid
Cleanliness, more environmentally-friendly health.
Furtherly, the upper end of described valve rod 2 connects handwheel 10.In use, operator can be led to
Cross rotation hand wheel 10 and make valve plate 3 rise or fall under the effect of valve rod 2, and then opening or closing this lock
Valve.
Compared with prior art, the valve rod 2 during this utility model has the advantage that this utility model and valve
Being provided with spill-proof assembly between lid 4, spill-proof assembly includes brass billet 5 and rubber ring 6, and brass billet 5 is set with
On valve rod 2, rubber ring 6 is wrapped on the outside of brass billet 5, thus by brass billet 5 and rubber ring 6
Combination, it is possible to reduce the friction between valve rod 2 and valve gap 4, thus prevent valve rod 2 from being rubbed and making
The generation of leak case become, enhances the sealing property of valve rod 2, extends valve rod 2 and whole gate valve
In service life, go for various operating mode.It is positioned at below spill-proof assembly it addition, be additionally provided with on valve rod 2
Sealing ring 9, not only increase sealing property, and under valve plate 3 and valve rod 2 lifting state, can be very
Change this sealing ring 9 easily, strengthen the serviceability of this gate valve.
The foregoing is only embodiment of the present utility model, not thereby limit patent model of the present utility model
Enclose, every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion,
Or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in patent of the present utility model
