Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a special opening and closing valve device for industrial refrigeration equipment. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] In the special on-off valves for industrial refrigeration equipment, the valves are often frozen due to the low temperature in the refrigeration equipment pipelines. It is difficult to control the opening and closing of the valves when they are frozen, and when there is ice at the valve position, the valve core is easily damaged, resulting in the valve being unable to be used normally. For traditional on-off valves, the sealing plate above the valve and the valve body are mostly detachably connected by nuts. After a long period of use, the water in the valve body is easy to overflow through the gap between the sealing plate and the valve body, making the sealing of the on-off valve poor.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 4 In the embodiment of the utility model, a special opening and closing valve device for industrial refrigeration equipment includes a main valve body 1, a spiral rotating rod 15 is rotatably connected to the middle of the inner bottom end of the main valve body 1, four arc-shaped fixed frame plates 17 are evenly distributed at the bottom end of the outer side of the spiral rotating rod 15, and a filter screen 18 is fixedly connected between each group of arc-shaped fixed frame plates 17, a rotating rod 13 is slidably connected to the top of the outer side of the spiral rotating rod 15, and a first vortex fan 14 is rotatably connected to the bottom end of the rotating rod 13, a sealing valve block 19 is provided at the top of the inner side of the main valve body 1, and a second vortex fan 20 is provided in the middle below the sealing valve block 19. The middle part of the second vortex fan 20 is fixedly connected to the outer side of the rotating rod 13, the middle part of the top end of the sealing valve block 19 is rotatably connected with the adjusting push rod 7, the rotating rod 13 passes through the middle part of the adjusting push rod 7, and a motor 21 is provided above the adjusting push rod 7. The middle part of the bottom end of the motor 21 is fixedly connected to the middle part of the top end of the rotating rod 13, the middle part of the front side of the main valve body 1 is provided with a water inlet 2, the middle part of the rear side of the main valve body 1 is provided with a water outlet 12, the middle part of the inner side of the main valve body 1 is provided with a valve cavity port 16, the first vortex fan 14 is located above the valve cavity port 16, and the cross-sectional shape of the side view of the sealing valve block 19 is an isosceles trapezoid.

[0022] In this embodiment: when in use, the motor 21 drives the second vortex fan 20 to rotate through the rotating rod 13 fixedly connected to the output end, and beats the water flow below the valve cavity port 16, thereby increasing the flow rate of the water flow below the valve cavity port 16 so that the temperature of the water flow gradually rises. The heated water flow melts the ice contained in the water flow below the valve cavity port 16, and then rotates the adjusting push rod 7 to make the adjusting push rod 7 slide upward, thereby driving the sealing valve block 19 rotatably connected below the adjusting push rod 7 to slide upward to the inner side of the main valve body 1 and separate from the valve cavity port 16. When the sealing valve block 19 slides upward, it will drive the rotating rod 13 connected in the middle to one end upward, thereby driving the first scroll fan 14 connected to the outer bottom of the rotating rod 13 to move upward. During the upward movement of the rotating rod 13, the spiral cavity inside it will move upward along the thread fixedly connected to the outer top of the spiral rotating rod 15. At this time, the upwardly moving rotating rod 13 will drive the spiral rotating rod 15 to rotate. The rotating spiral rotating rod 15 will drive the filter screen 18 fixedly connected to the outer side of the arc-shaped fixed frame plate 17 through the arc-shaped fixed frame plate 17 fixedly connected to the outer bottom end to rotate, The water flow rate around the filter 18 is increased, so that the ice around the filter 18 is filtered and melted. When the first vortex fan 14 moves up to the upper side of the inner side of the valve cavity opening 16, the rotation of the adjusting push rod 7 is stopped. At this time, the water flows into the main valve body 1 through the water inlet 2. When the water flows in contact with the filter 18, it passes through the filter 18 and enters the filter cavity composed of the arc-shaped fixed frame plate 17 and the filter 18. When the water flows in contact with the first vortex fan 14, the water flow will drive the first vortex fan 14 to rotate, and the rotating first vortex fan 14 will cause the water to flow in. The motor 21 drives the rotating rod 13 fixedly connected to the output end to rotate, and the rotating rod 13 drives the second vortex fan 20 to rotate. The second vortex fan 20 will beat the water flow during its rotation, thereby increasing the flow rate of the water flow. The water flow beat by the water slowly heats up to melt the ice chips contained in the water flow, preventing the water temperature from being too low and affecting the use effect of the sealing valve block 19. The heated water flow is discharged through the water outlet 12, which is convenient for beating the flowing water flow to increase the flow rate and thus increase the temperature of the water flow, preventing the temperature of the valve port from being too low to damage the valve.
