Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of many seal ball-valves.
Background technique
Ball valve is adapted to the general work media such as water, rock gas, artificial coal gas and liquefied petroleum gas (LPG), all indispensable in production and life, its main feature is compact structure own, is easy to Operation and maintenance, only needs to use the operation of 90-degree rotation and very little moment just can close tight.
In prior art, ball valve seal is independent a kind of material NBR or PTEF, in use, ball valve is difficult to balance between antagonism high pressure and low pressure, easily cause the wearing and tearing of Sealing and leak, and once leak, can only let alone to leak, then wait for that specialized maintenance personnel show up replacing ball valve, not emergent encapsulation process structure, causes the great wasting of resources, if in the poisonous and hazardous situation of fluid of leaking, also can cause the very big pollution of surrounding enviroment, and serious harm health.
Therefore, need to develop a kind of ball valve, antagonism high pressure that can be good and low pressure, and once leak, emergency sealing process can be completed easily.
Model utility content
The purpose of this utility model is to provide a kind of many seal ball-valves, antagonism high pressure that can be good and low pressure, extends the working life of ball valve, and once leak, can complete emergency sealing process easily, avoids waste and the loss of resource.
For achieving the above object, technical solution adopted in the utility model is:
A kind of many seal ball-valves, comprise the emergency treatment device of valve body, valve seat, valve ball, valve rod, handle, tightening nut, dynamic sealing means and leakage, described valve seat and described valve ball are arranged in described valve body, described valve rod is fixedly connected with described valve ball, described dynamic sealing means is arranged between described valve body and described valve rod, and described valve body and described valve rod are tightly connected by described dynamic sealing means; Described handle is arranged at described valve rod top, and is fixedly connected with described valve rod by described tightening nut; It is characterized in that, described dynamic sealing means comprises the lower plain cushion, O RunddichtringO B, O RunddichtringO A and the upper plain cushion that set gradually from top to bottom; The emergency treatment device of described leakage is arranged between described dynamic sealing means and described handle, and the emergency treatment device of described leakage comprises copper sheet and emergency processing nut; The external diameter of described copper sheet is less than or equal to the external diameter of described upper plain cushion, and described copper sheet is closely set in the top of described upper plain cushion, and described emergency processing nut is closely set in the top of described copper sheet.
Further, described valve body and described valve rod are respectively arranged with upper and lower two grooves, described upper plain cushion and lower plain cushion are arranged in two grooves up and down of described valve body respectively; Described O RunddichtringO A and described O RunddichtringO B is arranged in two grooves up and down of described valve rod respectively.
Further, described upper plain cushion and described lower levelling plate are respectively teflon gasket; Described O RunddichtringO A and described O RunddichtringO B is respectively nitrile butadiene rubber seal ring.
The beneficial effects of the utility model are:
The utility model adopts two plain cushions and two O RunddichtringOs, valve body and valve rod are sealed, sealing effect is better, and plain cushion and seal ring adopt NBR and PTFE two kinds of materials to make, achieve the perfection sealing of valve body and valve rod under high pressure and low pressure, in addition, the utility model also add the emergency treatment device of leakage, when occurring to leak, emergency treatment device can be adopted to carry out urgent leak-stopping process, do not need to wait until always specialized maintenance personnel show up can leak-stopping, avoid the waste of resource.The utility model can be good antagonism high pressure and low pressure, extend the working life of ball valve, and once leak, emergency sealing process can be completed easily, avoid waste and the loss of resource.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
As shown in accompanying drawing 1 ~ 2, a kind of many seal ball-valves, comprise the emergency treatment device of valve body 1, valve seat 2, valve ball 3, valve rod 4, handle 5, tightening nut 6, dynamic sealing means and leakage, described valve seat 2 and described valve ball 3 are arranged in described valve body 1, described valve rod 4 is fixedly connected with described valve ball 3, described handle 5 is arranged at described valve rod 4 top, and is fixedly connected with described valve rod 4 by described tightening nut 6; Described dynamic sealing means is arranged between described valve body 1 and described valve rod 4, and described valve body 1 and described valve rod 4 are tightly connected by described dynamic sealing means; Described dynamic sealing means comprises the lower plain cushion 7, O RunddichtringO B10, O RunddichtringO A9 and the upper plain cushion 8 that set gradually from top to bottom; The utility model seal arrangement includes two plain cushions and two O RunddichtringOs, adopts comparatively separately single O RunddichtringO or adopts separately the sealing effect of single plain cushion more excellent; The emergency treatment device of described leakage is arranged between described dynamic sealing means and described handle 5, and the emergency treatment device of described leakage comprises copper sheet 11 and emergency processing nut 12; The external diameter of described copper sheet 11 is less than or equal to the external diameter of described upper plain cushion 8, and described copper sheet 11 is closely set in the top of described upper plain cushion 8, and described emergency processing nut 12 is closely set in the top of described copper sheet 11.When O RunddichtringO lost efficacy generation leakage in Long-Time Service process, only need clockwise fastening emergent nut, described copper sheet 11 moves down simultaneously, radial deformation is there is in described upper plain cushion 8 and described lower plain cushion 7 under the effect of axial force coming from copper sheet 11, tightr with contacting of described valve rod 4 with described valve body 1, thus realize emergent sealing.
According to a kind of many seal ball-valves of a preferred embodiment of the present utility model, described valve body 1 and described valve rod 4 are respectively arranged with upper and lower two grooves, and described upper plain cushion 8 and lower plain cushion 7 are arranged in two grooves up and down of described valve body 1 respectively; Described O RunddichtringO A9 and described O RunddichtringO B10 is arranged in two grooves up and down of described valve rod 4 respectively.Described plain cushion and the capable seal ring of described O are arranged on described valve body 1 and described valve rod 4 respectively, make sealing effect more remarkable.
According to a kind of many seal ball-valves of a preferred embodiment of the present utility model, it is characterized in that, described upper plain cushion 8 and described lower levelling plate 7 are difference teflon gasket; Described O RunddichtringO A9 and described O RunddichtringO B10 is respectively nitrile butadiene rubber seal ring.The utility model adopts nitrile butadiene rubber material and teflon material to realize the sealing of described valve body 1 and described valve rod 4, effectively balances the shortcoming adopting single material to bring, thus achieves the perfection sealing under high pressure and low-pressure state.
