Abstract
The utility model discloses a valve rod nut which is easy to remove faults. The valve rod nut of a rising rod parallel double-flashboard valve is frequently damaged caused by the factors of frequent operations, unavoidable non-standard operations, material quality, etc. The damage results in the valve to be unworkable. When the fault is eliminated, the production needs to stop, and the pressure needs to be released, which bring large loss for production. Compared with the existing nut, the valve rod nut provided by the utility model is not easy to damage. After the valve rod nut is damaged, the valve rod nut can remove faults under the condition that the production is not stopped, and the pressure is not released. The valve rod nut has easy manufacture, and the maintaining device of a general factory can all manufacture the valve rod nut.
Description
It is used that the utility model belongs to the Double Disk Parallel Gate Valves valve.
When existing Double Disk Parallel Gate Valves valve (being Z44 series) reality is used.Because the restriction of process conditions, usually often opening and closing.Because this valve is usually used in chemical industry, the valve rod of valve and Stem Mut are vulnerable to the topped of the erosion of harmful gas and dust again, add material factors and inevitably Chang Yi such as non-standard operation cause the damage of Stem Mut.After Stem Mut damaged, the complete akinesia of valve had destroyed process conditions.When repairing valve, need to stop production and valve pressure is released the renovation technique more complicated.Because of the stop production phenomenon of repairing of the damage of valve of common occurrence.The loss that causes is huge.
One of the purpose of this utility model is to provide a kind of Stem Mut that can conveniently fix a breakdown to the producer that produces valve, and need not stop production after this nut damages just can be replaced.Production valve plant uses factory that a kind of new model product is provided to valve when not increasing cost, makes corresponding valve satisfy process conditions.Two of purpose is to use the technology of the existing Stem Mut of transformation that factory provides very simple, reforming cost is cheap to valve, avoids the loss that stops production.
One end of said novel Stem Mut has left-handed and two sections screw rods and corresponding nut dextrorotation.Wherein left-handed screw cap is a stressed nut, and right-handed screw cap is a jam nut.The other end is a step, and when this Stem Mut was installed on the Double Disk Parallel Gate Valves valve, the step end was always on threaded end.
The utility model is compared with existing Stem Mut, has following good effect or advantage at least: can not cause stopping production, the loss of having avoided manufacturer to cause thus when getting rid of the Stem Mut fault of valve; It is convenient, simple to change Stem Mut; Not fragile; The maintenance of equipment of general factory all can be made, and produces simple.
Below accompanying drawing is done an explanation: Fig. 1 is that novel Stem Mut is installed in the schematic representation on the Double Disk Parallel Gate Valves valve.1 is valve rod among Fig. 1, the 2nd, and novel Stem Mut, the 3rd, key, the 4th, handwheel, the 5th, valve gap, the 6th, left-handed stressed nut, the 7th, jam nut.Fig. 2 is that existing Stem Mut is installed in the schematic representation on the Double Disk Parallel Gate Valves valve.1 is valve rod among Fig. 2, the 2nd, and existing Stem Mut, the 4th, handwheel, the 5th, valve gap, the 6th, lock nut.
As can be seen from Figure 2, after Stem Mut damaged, because the step of this nut and valve gap cooperate, this Stem Mut can not withdraw from valve rod, unless lay down valve body (not drawing among the figure).As can be seen from Figure 1.After novel Stem Mut damages, only need loosening nut 6 and 7, just this Stem Mut can be withdrawed from valve rod and change.
Claims (1)
- A kind of Stem Mut that is used for the Double Disk Parallel Gate Valves valve, it is characterized in that Stem Mut one end has left-handed and two sections screw rods and corresponding nut dextrorotation, the other end of Stem Mut has step, and when being installed on the said valve, the step of Stem Mut is always on threaded end.
