Description

Technical Field

[0001] This utility model relates to the field of pressure reducing valve technology, specifically an adjustable intelligent pressure reducing valve. Background Technology

[0002] An adjustable intelligent pressure reducing valve is a device installed in a fluid pipeline that can be manually or automatically adjusted to reduce and stabilize the fluid pressure within a set range. This type of valve typically has a higher level of automation and intelligence, and can perform precise pressure regulation according to actual needs.

[0003] In the existing technology, since adjustable intelligent pressure reducing valves usually use mechanical or electronic adjustment mechanisms, their sensitivity may be affected by the external environment, such as temperature, humidity, vibration, etc., which will lead to adjustment errors. In addition, adjustable intelligent pressure reducing valves need to be maintained and calibrated regularly to ensure their performance and accuracy, which increases the cost of use and time.

[0004] Therefore, an adjustable intelligent pressure reducing valve is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable intelligent pressure reducing valve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable intelligent pressure reducing valve, comprising a lower valve body, an upper valve body snapped onto the top of the lower valve body, multiple snap-fit ​​shells fixedly connected to the sides of the lower and upper valve bodies that are close to each other, the snap-fit ​​shells on the outer walls of the lower and upper valve bodies snapping against each other in pairs, a positioning bolt threaded into the middle of each pair of snap-fit ​​shells, a controller fixedly connected to the top of the upper valve body, multiple heat sinks fixedly connected at equal intervals to the outer wall of the controller, and multiple bent tubes for constant temperature fixedly connected at equal intervals to the outer wall of the controller.

[0007] Preferably, a temperature controller is fixedly connected to the top of the controller, an inlet pipe is fixedly connected to one side of the temperature controller, an outlet pipe is fixedly connected to the other side of the temperature controller, and a second ring pipe is fixedly connected to the outer ends of the outlet pipe and the inlet pipe. The second ring pipe is fixedly connected to the top edge of the controller.

[0008] Preferably, all of the multiple bent tubes are vertically L-shaped, and the bottom of each bent tube is fixedly connected to the top of the upper valve body. The side of each bent tube away from the second ring tube is fixedly connected to the first ring tube.

[0009] Preferably, the top of the thermostat is fixedly connected to an upper soft pad, the bottom of the lower valve body is fixedly connected to a fastening bolt, the bottom of the fastening bolt is fixedly connected to a lower soft pad, one side of the middle of the lower valve body is fixedly connected to a water inlet, the other side of the middle of the lower valve body is fixedly connected to a water outlet, and the outer walls of the water inlet and the water outlet are movably fitted with rubber rings.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Through the arrangement of the first ring pipe, the second ring pipe, and the bend pipe, the liquid flows to the second ring pipe and is dispersed into the bend pipe, and finally converges into the first ring pipe. Then it flows back through the inlet pipe, circulating repeatedly. It is evenly distributed on the outer wall of the controller and in the gaps of the heat sink through the bend pipe. At high temperatures, the coolant temperature is low, and the heat is absorbed through the bend pipe. At low temperatures, the coolant temperature is high, and the heat is released in the opposite direction through the bend pipe, maintaining the controller's temperature constant, thereby improving its adjustment accuracy and thus improving the sensitivity of the pressure reducing valve adjustment mechanism.

[0012] 2. By setting up upper and lower soft pads and rubber rings, the rubber rings can increase frictional resistance and reduce frictional vibration. Together with the upper and lower soft pads, the device will not directly collide with other pipelines when it vibrates. The upper and lower soft pads reduce the impact force, increase the protective performance, reduce the degree of environmental change of the pressure reducing valve parts, extend the service life, and reduce maintenance and time costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 An embodiment of this utility model is provided: an adjustable intelligent pressure reducing valve, including a lower valve body 1, an upper valve body 2 snapped onto the top of the lower valve body 1, multiple snap-fit ​​shells 6 fixedly connected to the sides of the lower valve body 1 and the upper valve body 2 that are close to each other, the snap-fit ​​shells 6 on the outer walls of the lower valve body 1 and the upper valve body 2 snap-fit ​​in pairs, a positioning bolt 7 is threadedly connected to the middle of each pair of snap-fit ​​shells 6, a controller 9 is fixedly connected to the top of the upper valve body 2, multiple heat sinks 8 are fixedly connected at equal intervals to the outer wall of the controller 9, and multiple bent tubes 16 for constant temperature are fixedly connected at equal intervals to the outer wall of the controller 9.

[0021] A temperature controller 14 is fixedly connected to the top of the controller 9. An inlet pipe 18 is fixedly connected to one side of the temperature controller 14, and an outlet pipe 17 is fixedly connected to the other side of the temperature controller 14. A second ring pipe 15 is fixedly connected to the outer end of the outlet pipe 17 and the inlet pipe 18. The second ring pipe 15 is fixedly connected to the top edge of the controller 9.

[0022] Multiple bent tubes 16 are all vertical L-shaped, and the bottom of each bent tube 16 is fixedly connected to the top of the upper valve body 2. The side of the bent tubes 16 away from the second ring tube 15 is fixedly connected to the first ring tube 10.

[0023] Specifically: at high temperatures, the coolant temperature is low, and heat is absorbed through the bend pipe 16; at low temperatures, the coolant temperature is high, and heat is released in the opposite direction through the bend pipe 16, thus maintaining the temperature of the controller 9 constant and improving its adjustment accuracy.

[0024] The thermostat 14 is fixedly connected to the top of the upper soft pad 13, the lower valve body 1 is fixedly connected to the bottom of the lower valve body 1 with a fastening bolt 5, the bottom of the fastening bolt 5 is fixedly connected to the lower soft pad 11, the lower valve body 1 is fixedly connected to one side of the middle part of the lower valve body 1 with a water inlet 3, the lower valve body 1 is fixedly connected to the other side of the middle part of the lower valve body 1 with a water outlet 4, and the outer walls of the water inlet 3 and the water outlet 4 are movably fitted with rubber rings 12.

[0025] Among them, the rubber ring 12 can increase frictional resistance and reduce frictional vibration. Together with the upper soft pad 13 and the lower soft pad 11, it can prevent the device from directly colliding with other pipelines when the whole device vibrates. The upper soft pad 13 and the lower soft pad 11 reduce the impact force and increase the protection performance, so that the environmental change of the pressure reducing valve parts is low.

[0026] The working principle of the above embodiment is as follows: In use, the constant temperature liquid is pumped out from the outlet pipe 17 by the temperature controller 14. The liquid flows to the second ring pipe 15 and is dispersed into the bent pipe 16. Finally, it gathers in the first ring pipe 10 and then flows back through the inlet pipe 18. The cycle repeats. The liquid is evenly distributed on the outer wall of the controller 9 and in the gap of the heat sink 8 through the bent pipe 16. At high temperature, the coolant temperature is low, and the heat is absorbed through the bent pipe 16. At low temperature, the coolant temperature is high, and the heat is released in the opposite direction through the bent pipe 16 to maintain the temperature of the controller 9 constant, thereby improving its adjustment accuracy. At the same time, when water flows through the lower valve body 1, the water pressure causes the water flow to vibrate slightly, which may cause friction and loosening at the connection between the inlet 3 and the outlet 4. The rubber ring 12 can increase the friction resistance and reduce friction vibration. With the upper soft pad 13 and the lower soft pad 11, the device will not collide directly with other pipes when the whole device vibrates. The upper soft pad 13 and the lower soft pad 11 reduce the impact force and increase the protection performance.
