Description

Technical Field

[0001] The utility model relates to the field of regulating valves, in particular to a self-operated high-temperature pressure regulating valve with a condenser. Background Art

[0002] The structure of the self-operated pressure regulating valve is relatively simple, mainly composed of valve body, valve disc, spring, guide, adjusting nut and other parts. Its working principle is to adjust the pressure by adjusting the spring pressure and the size of the valve disc opening. When the input fluid pressure increases, the valve disc shrinks, reducing the flow area of ​​the output fluid, thereby reducing the pressure of the output fluid. On the contrary, when the input fluid pressure drops, the valve disc opens, increasing the flow area of ​​the output fluid, thereby increasing the pressure of the output fluid. The self-operated pressure regulating valve with condenser is a pressure regulating device based on the principle of self-action. When the internal pressure of the system exceeds the set value, the valve opens, part of the medium is cooled through the condenser, and the remaining medium is discharged through the valve, thereby reducing the system pressure. Self-operated pressure regulating valves are widely used in the production and transportation processes of petroleum, chemical, pharmaceutical, food and other industries to ensure the stability and safety of system pressure.

[0003] In the prior art, a Chinese utility model patent with the announcement number of "CN217381795U" and the patent name of "a self-operated pressure regulating valve with good stability" discloses a self-operated pressure regulating valve. The patent records the technical solutions such as "the threaded setting of the connection hole and the fixing bolt facilitates the combined installation of the second connecting pipe, the rubber ring and the third connecting pipe, reduces the gap between the structures, enhances the sealing performance of the second connecting pipe and the third connecting pipe, has good stability, and the protective shell can protect and limit the pressure pipe to avoid damage to the pressure pipe caused by external factors. Moreover, the stable flow path is easy for the self-operated pressure regulating valve to play its function, and has a strong stabilizing effect". However, in the actual use of the self-operated pressure regulating valve, since the medium being transported may contain some impurities and the self-operated pressure regulating valve lacks corresponding filtering measures, the impurities in the medium enter the interior of the valve and after long-term use, the impurities will accumulate in the valve and cause the valve body to be blocked, thereby affecting the normal operation of the regulating valve. In order to solve this technical problem, the utility model proposes a self-operated high-temperature pressure regulating valve with a condenser. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 - Figure 4 As shown, in this embodiment, in order to prevent the impurities in the medium from accumulating inside the self-operated high-temperature pressure regulating valve with a condenser through the filtering mechanism 4, thereby causing blockage and affecting its normal use, the specific use principle of the filtering mechanism 4 in conjunction with the self-operated high-temperature pressure regulating valve with a condenser is as follows:

[0021] The outlet pipe 6 on the right side of the filter box 5 is installed to the input end of the valve body 1 through the flange. Then, according to the mesh size of the filter screen 13 installed in the three filter frames 11, the three filter frames 11 are installed from the bottom of the filter box 5 to the filter box 5 in order from small to large and from left to right. After installation, the insert strip 10 installed in the filter box 5 is inserted into the slot 12 opened on the front and rear side walls of the filter frame 11. Then, the bottom cover 23 is installed to the bottom surface of the filter box 5, and the raised frame 25 installed on the top surface of the bottom cover 23 is inserted into the sealing groove 8 opened on the bottom surface of the filter box 5. The filter box 5 is sealed with the sealing rubber frame 9 installed in the sealing groove 8, and then the threaded knob 21 installed on the outer wall of the side frame 14 installed on both sides of the bottom of the front and rear sides of the filter box 5 is rotated. The threaded knob 21 will realize threaded rotation in the screw hole 16 opened on the outer wall of the side frame 14, and the threaded knob 21 will drive the rotating block 22 on the inner end to rotate in the convex groove 20 opened on the outer wall of the movable plate 17, and when the threaded knob 21 is continuously rotated, the movable plate 17 will be pushed to move in the side frame 14 through the rotating block 22, and when the movable plate 17 moves, The sliders 18 installed on both sides of the movable plate 17 will slide in the sliding openings 15 opened on both sides of the side frame 14 until the card plates 19 installed on the inner side walls of the movable plate 17 are correspondingly inserted into the card slots 24 opened on the front and rear walls of the bottom cover 23, so as to fix the bottom cover 23 on the bottom surface of the filter box 5. Before the medium in the pipeline enters the valve body 1 through the input end, it will enter the filter box 5 through the water inlet pipe 7 on the left side of the filter box 5, and when it is discharged from the filter box 5 through the water outlet pipe 6 and then enters the valve body 1 through the input end, the three filter frames 11 installed from left to right in the filter box 5 will The large, medium and small impurities in the medium are intercepted and filtered in turn through the internally installed filter screen 13, which not only improves the filtering effect of the impurities in the medium, but also can effectively prevent the impurities from entering the valve body 1 with the medium and accumulating in the valve body 1 after long-term use to cause blockage, thereby ensuring the normal use of the self-operated high-temperature pressure regulating valve. Finally, after rotating the threaded knob 21 to remove the card plate 19 from the card slot 24, the box bottom cover 23 can be removed from the bottom of the filter box 5, so as to facilitate the cleaning of the impurities filtered out of the filter box 5 and the filter screen 13 at a later time.
