Abstract
The utility model relates to a fluid seal combination cut-off valve, which includes an inlet valve and an outlet valve, wherein an outlet end of the inlet valve is communicated with an inlet end of the outlet valve. The fluid seal combination cut-off valve further includes a fluid incoming control valve and a fluid outgoing control valve, wherein an outlet end of the fluid incoming control valve and an inlet end of the fluid outgoing control valve are both communicated with the outlet end of the inlet valve. Through adopting the technical scheme, the utility model provides the fluid seal combination cut-off valve, which can ensure the complete seal of the valve after long-term use.
Description
Technical field
The utility model relates to valve field, particularly a kind of fluid-tight combination cut-off valve.
Background technique
For poisonous, inflammable, explosive gas mediums such as coke oven, coal gas; Require valve to have long-term reliable sealing performance fully, yet existing valve uses the back for a long time because a variety of causes; As impurity be stained with on the valve sealing face, the wearing and tearing of sealing surface etc.; Cause valve reliable sealing fully, therefore, complete reliable sealing how to guarantee valve is the problem of valve field solution too impatient to wait.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of fluid-tight combination cut-off valve, after the long-term use of valve, still can guarantee the sealing fully of valve.
The technological scheme of the utility model: a kind of fluid-tight combination cut-off valve; Include inlet valve, outlet valve; The entry end conducting of the outlet end of described inlet valve and outlet valve; Also include fluid inflow control valve, fluid outflow control valve, the entry end of the outlet end of described fluid inflow control valve, fluid outflow control valve all with the outlet end conducting of inlet valve.
Adopt technique scheme, when needs cut off medium transport, only need inlet valve, outlet valve be closed simultaneously; Then; Open described fluid inflow control valve, charge into fluid to the inlet valve outlet end, fluid can be nontoxic liquid medium; Also can be nontoxic gas mediums such as air, nitrogen; Till the outlet end pressure of inlet valve was equal to or higher than the pressure of inlet valve entry end, the outlet end pressure of inlet valve can pass through gauge measurement, because the outlet end pressure of inlet valve is equal to or higher than the pressure of inlet valve entry end; Therefore, the medium of conveying can not leak into outlet end from the entry end of inlet valve; When the normal fed sheet of a media of needs, only need open described fluid outflow control valve, the fluid that charges into is discharged; Open inlet valve again, outlet valve gets final product; The fluid-tight combination cut-off valve of this structure after the long-term use of valve, still can guarantee the sealing fully of valve.
The further setting of the utility model: the outlet end of described inlet valve and the entry end of outlet valve are through the connecting tube conducting; Described connecting tube is provided with fluid flow ipe, the fluid outflow pipeline with the connecting tube conducting, and the entry end of the outlet end of described fluid inflow control valve, fluid outflow control valve flows out the pipeline conducting with fluid flow ipe, fluid respectively.
Adopt above-mentioned further setting; Realize the conducting of entry end of outlet end and the outlet valve of inlet valve through described connecting tube; Need inlet valve, outlet valve directly not connected like this; Can be not easy to damage inlet valve, outlet valve so that inlet valve, outlet valve are easy to connect; Increase the fluid flow ipe, fluid flows out pipeline, can be so that fluid inflow control valve, fluid outflow control valve be easy for installation.
Further being provided with again of the utility model: described inlet valve, outlet valve, fluid inflow control valve and fluid outflow control valve are gate valve, ball valve, stop valve or butterfly valve.
Adopt above-mentioned further setting again, can select different valve types according to different operating modes, using scope is wider.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1; A kind of fluid-tight combination cut-off valve; Include inlet valve 1, outlet valve 2, the outlet end 11 of described inlet valve 1 and the entry end 21 of outlet valve 2 are through connecting tube 3 conductings, and described connecting tube 3 all is fixedly connected through bolt 4 with the outlet end 11 of inlet valve 1, the entry end 21 of outlet valve 2; Can be convenient for changing inlet valve 1, outlet valve 2 according to different operating modes like this.Also include fluid inflow control valve 5, fluid outflow control valve 6 and flow out pipeline 8 with fluid flow ipe 7, the fluid of connecting tube 3 conductings; The outlet end 51 of described fluid inflow control valve 5, the entry end 61 of fluid outflow control valve 6 flow out pipeline 8 conductings with fluid flow ipe 7, fluid respectively; The outlet end 51 of described fluid inflow control valve 5, the entry end 61 of fluid outflow control valve 6 flow out pipeline 8 with fluid flow ipe 7, fluid respectively and are welded to connect; Described fluid flow ipe 7, fluid flow out pipeline 8 and all are welded to connect with connecting tube 3; General fluid inflow control valve 5, fluid outflow control valve 6 do not need frequent replacing; Therefore, being welded to connect is more firm Placement.
In the utility model specific embodiment, described inlet valve 1, outlet valve 2 are butterfly valve, and described fluid inflow control valve 5, fluid outflow control valve 6 are stop valve.
