Description
Technical field
The utility model belongs to industrial valve technical field, is specifically related to a kind of Novel marine flange stainless steel stop valve.
Background technique
At present, according to our domestic CB/T 3942 flange stainless steel stop valve standard, the Placement of flange stainless steel stop valve valve disc peculiar to vessel and valve rod generally adopts structure as shown in Figure 1: valve rod 4 end processes annular square groove, place the semicircular ring 300 that processes in annular square groove, then with the platen 200 of a threaded hexagon head or opposite side and pressure plate stud stator 100, valve rod 4 is fixed on valve disc 2.
The shortcoming of this structure is:
1) valve disc machining position is many, particularly the helical thread portion of machining valve disc, and required precision is greatly highly difficult; 2) part that configures of this structure is many: have valve disc, valve rod, semicircular ring, platen and pressure plate stud stator to amount to five parts, and each part must carry out machining making, affects manufacturing efficiency;
3) assembling is not easy, and particularly valve rod coordinates with the assembling of valve disc, higher to the skill set requirements of operator.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of Novel marine flange stainless steel stop valve, has the advantages that structure is simple, processing efficiency is high, cost is low, easy accessibility, performance are better.
The main technical schemes that the utility model adopts is: a kind of Novel marine flange stainless steel stop valve, comprise valve body and valve rod, the upper end of described valve body is fixed with valve gap by fastening piece, valve gap is fixed with thread bush by the end of self integrated adjutage, described valve rod is by thread bush and valve gap vertical orientation and the two ends of valve rod are connected to handwheel and valve disc respectively, it is characterized in that: described valve disc and valve rod respectively have the large semicircular arc-shaped groove such as circle on same level height, described groove encloses adjacent steel ball built with one, the arbitrary substantially horizontal of described valve disc inwardly has a screw channel be communicated with groove, lock screw is installed with in described screw channel.
The utility model also adopts following attached technological scheme:
In above-mentioned stop valve, the path of described screw channel is greater than the diameter of steel ball.
The beneficial effect adopting the utility model to bring is:
1) valve disc no longer needs machining large gauge screw thread, and machining place structure is simple, the single part machining productivity of raising;
2) required part is few, valve disc, valve rod, steel ball, Cock screw is only needed to amount to four parts, and carry out a mach part valve disc and valve rod, steel ball, lock screw are NBS part, can volume procurement from the market, reduce machining cost and the cost of raw material generally, improve the finished product market competitiveness;
3) assemble simple and easy, dismantle more convenient, improve operator's working efficiency;
4) more reliable performance, valve in use valve disc and the valve rod situation of disengaging can not occur;
5) constructional appearance of stop valve is better, takies valve flowing channel space few, reduces media flow passage resistance, more energy-conservation.
Accompanying drawing explanation
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the structural representation at prior art stop valve X place;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structure for amplifying schematic diagram at the utility model X place.
The label that wherein component names is corresponding is as follows:
Valve body 1, valve disc 2, valve gap 3, valve rod 4, groove 5, screw channel 6, thread bush 9, handwheel 10, fastening piece 16, steel ball 18, lock screw 19, pressure plate stud stator 100, platen 200, semicircular ring 300.
Embodiment
As Figure 2-3, a kind of Novel marine flange stainless steel stop valve, comprise valve body 1 and valve rod 4, the upper end of described valve body 1 is fixed with valve gap 3 by fastening piece 16, valve gap 3 is fixed with thread bush 9 by the end of self integrated adjutage, described valve rod 4 is by thread bush 9 and valve gap 3 vertical orientation and the two ends of valve rod 4 are connected to handwheel 10 and valve disc 2 respectively, it is characterized in that: described valve disc 2 and valve rod 4 respectively have the large semicircular arc-shaped groove 5 such as circle on same level height, described groove 5 encloses adjacent steel ball 18 built with one, the arbitrary substantially horizontal of described valve disc 2 inwardly has a screw channel 6 be communicated with groove 5, lock screw 19 is installed with in described screw channel 6, the path of described screw channel 6 internal thread is slightly larger than the diameter of steel ball 18, prevent steel ball 18 from can not be entered in annular groove 5 by screw channel 6 smoothly.
By said structure, the utility model stop valve has following basic mechanical design feature index:
1. design and manufaction standard is met: CB/T 3942-2002;
2. valve examination and test standard is met: GB/T 600-2008;
3. flange connection standard is met: GB/T 2501-2010;
4. inside nominal diameter: DN15-300;
5. nominal pressure: 0.6/1.0/1.6/2.5/4.0MPa;
6. medium temperature range :-40 ~ 425 ° of C;
7. Applicable media: the clean free from admixture fluids such as fresh water, seawater, oil product, steam;
8. suitable application area: the field such as industry, agricultural, boats and ships, national defence.
The installation process of stop valve steel ball 18 is as follows: be first rotated down handwheel 10, the end of valve rod 4 being pushed up valve disc 2 makes two ring shape semicircular ring grooves 5 of valve disc 2 and valve rod 4 synthesize a circle annulus, then steel ball 18 is filled in annulus by screw channel 6 many ground, until each steel ball 18 is close to, finally screw in screw channel 6 by lock screw 19 steel ball 18 is fixed, finally realize valve rod 4 and valve disc 2 is synchronized with the movement.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
