Abstract
The utility model relates to valve technology field, especially a kind of industrial refrigeration right-angle type safety check.A kind of industrial refrigeration right-angle type safety check, comprise valve seat and valve gap, described valve seat is connected with bonnet flange, valve seat has vertically disposed inlet pipe body and goes out pipe body, inlet pipe body and go out between pipe body to be equipped with flap, the opening angle of described flap is 0 ~ 20 °, and flap is connected with spring, be provided with flap pad bottom flap, below flap pad, be provided with gland pad.Safety check after optimization reduces consumptive material, and the energy loss produced when decreasing manufacturing cost and run, is beneficial to environmental protection and energy saving, advocating of response energy-saving and emission-reduction, to raising energy utilization rate future development.
Description
Technical field
The utility model relates to valve technology field, especially a kind of industrial refrigeration right-angle type safety check.
Background technique
Valve is an important mechanical device in pipeline, by valve opening and closing, adjustment, and control apparatus and pipeline medium pressure, flow and direction.Valve classification is a lot, and safety check refers to and relies on medium itself to flow and automatic opening-closing flap, and allow the valve of medium one-way flow, protective conduit machinery plays an important role from water flow impulsion.Safety check working procedure water hammer temporary impact pressure may higher than the several times of normal operating pressure, and produce a very large impact the stability of system and functional reliability, the high-pressure duct system that multiple stage parallel connection of pumps is suitable for, the problem of water hammer of safety check is more outstanding.The service behaviour of safety check has direct impact to whole system performance, and the opening-closing process of flap is subject to the impact of systemic transient flowing state residing for it, and meanwhile, the open and shut characteristic of flap is to the also generation effect of media flow state.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of industrial refrigeration right-angle type safety check.
The utility model solves the technological scheme that its technical problem adopts: a kind of industrial refrigeration right-angle type safety check, comprise valve seat and valve gap, described valve seat is connected with bonnet flange, valve seat has vertically disposed inlet pipe body and goes out pipe body, inlet pipe body and go out between pipe body to be equipped with flap, the opening angle of described flap is 0 ~ 20 °, and flap is connected with spring, be provided with flap pad bottom flap, below flap pad, be provided with gland pad.
Further, the position that described flap top contacts with valve gap is provided with O type circle.
The beneficial effects of the utility model are: the safety check after optimization reduces consumptive material, and the energy loss produced when decreasing manufacturing cost and run, is beneficial to environmental protection and energy saving, advocating of response energy-saving and emission-reduction, to raising energy utilization rate future development.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve seat, 2. valve gap, 3. flap, 4. spring, 5. flap pad, 6. gland pad, 7.O type circle, 11. inlet pipe bodys, 12. go out pipe body.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of industrial refrigeration right-angle type safety check, comprise valve seat 1 and valve gap 2, valve seat 1 and valve gap 2 Flange joint, valve seat 1 has vertically disposed inlet pipe body 11 and goes out pipe body 12, inlet pipe body 11 and go out between pipe body 12 to be equipped with flap 3, the opening angle of flap 3 is 0 ~ 20 °, flap 3 is connected with spring 4, is provided with flap pad 5 bottom flap 3, flap pad 5 is provided with gland pad 6 below.
Further, the position that flap 3 top contacts with valve gap 2 is provided with O type circle 7.
When flap 3 standard-sized sheet, when namely the opening angle of flap 3 is 20 °, the pressure drop that safety check produces is less, and the flap that medium causes vibrates, the pulsation of medium is less, is best opening angle.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
