Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model must form water seal for commonly using in existing technology when Automatic steam trap Trap is used, be not suitable for the problem of superheated vapor occasion, a kind of Automatic steam trap Trap is provided, as shown in Figure 1, comprise valve body 10, there is valve gap 20, bimetallic strip assembly 30, filter screen 4 and the pad 5 of cavity, described valve gap 20 is covered on described valve body 10, described bimetallic strip assembly 30 is arranged in the cavity 21 of described valve gap 20, it is characterized in that, described bimetallic strip assembly 30 comprises many group bimetallic strips 31, and described many group bimetallic strips 31 are arranged side by side.
As shown in Figures 2 and 3, wherein, the first width A that the Scantlings of the described Automatic steam trap Trap that the utility model embodiment provides is preferentially chosen as described bimetallic strip 31 is 31.75mm, and the second width B is 12.70mm, length C is 44.45mm, and thickness D is 2.00mm.
The described Automatic steam trap Trap that the utility model embodiment provides has bimetallic strip assembly, needn't form water seal in use, is applicable to superheated vapor occasion.Meanwhile, by changing the size of bimetallic strip, reached and reduced installation dimension, installed compactly, there is very large condensed water discharge capacity, reduced the effect of rate of fault.
Consider that bimetallic strip can expand when superheated vapor occasion, as shown in Figure 4, described in the described Automatic steam trap Trap that the utility model embodiment provides, many group bimetallic strips 31 are 6 groups, and between two adjacent groups, have the gap E of adjusting.
In order to prevent that many group bimetallic strips from producing wearing and tearing when expanding, as shown in Figure 4 and Figure 5, described in the described Automatic steam trap Trap that the utility model embodiment provides, bimetallic strip assembly 30 also comprises the pad 32 that is positioned at described adjusting gap E.
Concrete, as shown in Figure 5, described bimetallic strip assembly 30 also comprises: between described bimetallic strip 31 and the valve rods 33 that coordinate with described many group bimetallic strips 31, the valve seat 340, guide pin bushing 35, setting sleeve 36 and the nut 37 that coordinate with described valve rod 33, the support 38 coordinating with described guide pin bushing 35 and described valve seat 340; The locating stud 39 coordinating with described support 38 and described bimetallic strip 31.Wherein, the number of described locating stud 39 is 2, and two described locating studs 39 are symmetrical arranged about described valve rod 33.
As shown in Figure 4, described valve seat 340 has valve nozzle opening structure 341.In order to make the described Automatic steam trap Trap that the utility model embodiment provides can bear high pressure to a certain degree, the diameter F of the valve nozzle opening structure 341 of Automatic steam trap Trap described in the utility model embodiment is preferentially chosen as 5.38mm.
Further, as shown in Figure 1, described filter screen 4 is arranged between described valve body 10 and described bimetallic strip assembly 30; Described pad 5 is arranged in the groove 11 of described valve body 10.
In order to make the described Automatic steam trap Trap that the utility model embodiment provides can there is larger operating pressure differential, and bimetallic strip difficult inefficacy under High Temperature High Pressure, be difficult for breaking down, wherein,, the material of described bimetallic strip is kanthal; And described bimetallic strip is through being incubated 3 hours at 750 ℃, normal temperature air cooling then, the heat treatment of at least cooling 12 hours at 10 ℃ of temperature of refrigerator after assembling.After this heat treatment, in the operating temperature of described Automatic steam trap Trap, be limited to 540 ℃, and the maximum working pressure that now can bear is 13.7Mpa; On the operating pressure differential of described Automatic steam trap Trap, be limited to 12.4Mpa.Therefore the Automatic steam trap Trap that, the utility model embodiment provides can be resisted water hammer, condensed water corrodes and steam high pressure.
As shown in Figure 1, wherein, described valve body 10 has entrance pipe 12 and export pipeline 13, and wherein, described entrance pipe 12 and described export pipeline 13 are all communicated with the cavity 21 of described valve gap 20.The described Automatic steam trap Trap that the utility model embodiment provides is opened completely when the machine of rising, and can discharge smoothly air and a large amount of condensed waters.Because condensed water can be arranged the outlet from valve body smoothly, this steam valve can be not frozen.Even if freeze, due to valve body design, can not be damaged by frost yet, do not need insulation.
Illustrate the working procedure of the Automatic steam trap Trap that the utility model embodiment provides below.
As shown in Fig. 6, Fig. 7 and Fig. 8, during driving, drain valve temperature is low, and bimetallic strip is flat, valve opening standard-sized sheet, and air a and water of condensation b can discharge under operating pressure differential, flow to as shown in the Y-direction in figure; Along with the increase of water of condensation b temperature, have steam c and become with flash steam D-shaped, bimetallic strip starts expanded by heating distortion simultaneously; When temperature is increased to lower than 10 ℃ of corresponding saturated-steam temperatures of working pressure gradually, bi-metal plate deformed power is enough to overcome system pressure promotes valve rod, and valve opening is closed completely.
Bimetallic strip in the Automatic steam trap Trap that the utility model embodiment provides meets High Temperature High Pressure, and use the excellent kanthal of performance to do bimetallic strip, by special heat treatment, make bimetallic strip reach excellent performance, maximum operating pressure differential can be to 12.4MPa, Maximum operating temperature can reach 540 ℃, for a long time under operating mode, performance performance is stable, long service life, performance is better than product of the same trade, the maximum service pressure of bimetal drainage valve is significantly improved, and further improves the using scope of decelerator with bimetallic strips, meets harsh operating conditions; Project organization is compact; Select and forge material housing, to meet High Temperature High Pressure demand; The structure of drain valve is comparatively firm, and using scope is wider, is applicable to superheated vapor pipeline, steam tracing pipeline, insulation of equipment, heating for residential area, outdoor low temperature environment and allows to have the heating plant water delivery of condensed water in high temperature.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
