Abstract
The utility model relates to a double-safety stop valve which belongs to a pipe line valve. The utility model is added with a partition plate between seal filler and a valve core in the cavity of the prime stop valve; the structure, shape and material of the partition plate can be made on the ground of the model number, specifications and work conditions of the prime stop valve; the partition plate can in advance play the seal action for the prime seal filler. The utility model has the characteristics of simple structure, easy mounting and reforming, strong leakage effect preventing, largely increased service life of the stop valve, etc.
Description
The utility model belongs to pipeline valve, is a kind of dual fail-safe stop valve.
At present common stop valve mostly uses materials such as spunyarn, graphite to do filler and seals at the position that its lifting bar and valve gap place, and leaks avoiding.But in use,, cause poorly sealed and the formation leakage owing to water or other corrosive actiones in frequently rise and fall mobile and the pipeline of lifting bar are very easily damaged filler.The normal operation that not only influences equipment is used, and can cause waste and environmental pollution because of dielectric leakage.
The purpose of this utility model is to provide a kind of dual fail-safe stop valve, this stop valve is on the basis of existing stop valve structure, isolating plate is set up on top in the valve pocket inner spool, isolating plate and lifting bar cross-under, and be connected or be crimped on the binding site of valve gap and valve body with the valve pocket inner wall sealing.Seal jointly with filler 12, to overcome the existing in prior technology deficiency.
Overall structure of the present utility model is:
The dual fail-safe stop valve is made of valve body 1, valve gap 2, lifting bar 3 and the handwheel 4, the spool 5 that are installed in the lifting bar two ends, it is characterized in that isolating plate 6 is arranged in the valve pocket 7 on spool top, the top of isolating plate is connected with lifting bar 3 cross-under or with the spool of lifting bar end, the periphery of isolating plate and valve pocket inner circle wall are tightly connected or are crimped on the binding site of valve gap and valve body, and the longitudinal section of isolating plate is a kind of in broken line, wave molding or three kinds of shapes of camber line 6,13,15.
The assembling of different shape isolating plate is as follows:
The cross section is the valve pocket that undulatory metal isolating plate 13 is positioned at valve gap and valve body binding site, horizontal positioned, and two ring plates 14 with the upper and lower surface of bolton isolating plate are fixed on the cross-under of isolating plate central position on the lifting bar; To be nested with ring plate 10 in the lifting bar end with bolt, to make the cross section be that the upper-end surface 11 of the top of rubber isolating plate of polyline shaped and spool is fastening.
The cross section is that the bowl-shape isolating plate 15 of garden arcuation is positioned at valve pocket top, the arc top of isolating plate up with the lifting bar cross-under, the isolating plate periphery is crimped on the binding site of valve gap and valve body.
Accompanying drawing of the present utility model has:
Fig. 1 is the structure diagram of dual fail-safe stop valve.
Fig. 2 is isolating plate 6 sectional views.
Fig. 3 is the sectional view of isolating plate 13.
Fig. 4 is the sectional view of isolating plate 15.
Accompanying drawing has provided embodiment of the present utility model, further specifies as follows in conjunction with the accompanying drawings:
Its concrete model of stop valve of setting up isolating plate in valve pocket can be J41W-16, and specification is DN(mm) 100-250, be applicable to the pressure piping of 1.6Mpa, working medium is fluids such as water, vapour, oil, soda acid.If operating ambient temperature is lower than 80 ℃ the rubber isolating plate can be set in stop valve, it assembles as described above, and as shown in Figure 1, sectional shape is seen Fig. 2, if operating ambient temperature is lower than 250 ℃ and should selects stainless steel ripple shape isolating plate for use, its sectional shape is seen Fig. 3.The big I of each isolating plate is according to the valve pocket size design of different size stop valve, and all the other each members all are illustrated in figure 1 as conventional components.
The obtained technological progress of the utility model is:
This division board also can be made into other similar tablets, in valve pocket, arrange to adapt to the specification of different model stop valve, in use the flexible isolating sheet is with elevating lever, spool or be subjected to the upper and lower action of effect of valve pocket inner fluid, can play filler and give sealing function, because this division board is according to the flow media situation, select unlike material to make, so its anticorrosion, lure the erosion effect better. Therefore this Double-safety stop valve have simple in structure, be easy to original stop valve is reequiped and anti-leak, can increase substantially the characteristics such as stop valve service life.
Claims (3)
