Abstract
The invention relates to the technical field of valves, and in particular to a right-angle type check valve for industrial refrigeration. The right-angle type check valve for industrial refrigeration comprises a valve seat and a valve cover, wherein the valve seat is in flange connection with the valve cover, and the valve seat is provided with an inlet pipe body and an outlet pipe body which are vertically arranged; a valve clack is arranged between the inlet pipe body and the outlet pipe body in a matched manner, and the opening angle of the valve clack is 0-20 degrees; a spring is connected to the valve clack, and a valve clack gasket is arranged at the bottom of the valve clack; and a gland gasket is arranged under the valve clack gasket. By means of the optimized check valve, material consumption is reduced, and the production manufacturing cost and energy losses generated in operation are reduced; environmental protection and energy saving are facilitated, the check valve responds to the advocating of energy conservation and emission reduction; and the development toward energy utilization rate improvement is achieved.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of industrial refrigeration right-angle type safety check.
The technical solution adopted for the present invention to solve the technical problems is: provide 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 invention has the beneficial effects as follows: the safety check after optimization reduces consumptive material, 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 accompanying drawing embodiment, the present invention is further described.
Fig. 1 is structural representation of the present invention.
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
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
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 invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
Claims (2)
