Description

Technical Field

[0001] This utility model relates to the field of valve core assembly technology, and specifically to a valve core assembly for high-temperature environments. Background Technology

[0002] The valve core assembly consists of various connectors and valve cores, including ball valve cores and needle valve cores. The needle valve core is a slender cone that is inserted into the valve seat to different depths to control the precise flow rate. Traditional valve cores are easily affected by high temperatures during use, or when used in a high-temperature heat-melting environment, they are prone to thermal expansion. This causes the insertion depth to be affected by the coefficient of friction after expansion, which in turn affects the precise flow control of the entire valve core assembly and affects the efficiency of use.

[0003] Existing valve core assemblies are prone to thermal expansion and increased friction when used in high-temperature environments, affecting their performance. For example, a valve core assembly disclosed in CN205908838U includes a magnetic shielding tube, a moving iron core, and a stationary iron core. Inside the magnetic shielding tube, the moving iron core, the stationary iron core, and a ratchet assembly are sequentially connected from top to bottom. The ratchet assembly includes a ratchet body, a push wheel, a rotating wheel, and an elastic reset device. The ratchet body is fixed inside the magnetic shielding tube. The push wheel and the rotating wheel are axially movable within the ratchet body, and the push wheel and the rotating wheel mesh. The moving iron core abuts against the push wheel via a pin. The ratchet body also has grooves for the push wheel and the rotating wheel to move up and down. The grooves have a first position for locking the rotating wheel in a low position and a second position for locking the push wheel in a high position. The elastic reset device is driven by the rotating wheel. This utility model has a simple and reasonable structure, is easy to use, and has stable and reliable working performance. When the solenoid valve is working, its excitation coil does not need to be energized for a long time to maintain the open state, which has a good energy-saving effect and helps to extend the service life of the solenoid valve. However, this valve core assembly cannot cool the valve core assembly, and the high temperature can easily affect the performance of the valve core assembly.

[0004] Therefore, it is necessary to invent a valve core assembly for high-temperature environments to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a valve core assembly for high-temperature environments, in order to solve the problem that valve core assemblies are easily affected by high temperatures, which increases expansion and friction, thus affecting their performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A valve core assembly for high-temperature environments includes a connecting bolt, a valve core body one, a valve core body two, a valve core body three, a valve core body four, and a sealing collar. The connecting bolt is threaded into the valve core body one. The valve core body two is located at the bottom of the valve core body one. The bottom of the valve core body two is connected to the valve core body three. The bottom of the valve core body three is located at the bottom of the valve core body four. The sealing collar is fitted at the bottom of the valve core body four. The surface of the valve core body two has multiple first ventilation holes, which correspond to first exhaust holes. The first exhaust holes are located on a movable sleeve. The valve core body four has evenly spaced second ventilation holes, which correspond to the second exhaust holes.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] 1. This utility model uses multiple springs set inside the entire valve core assembly. The elastic deformation of the springs compresses the movement of the valve core inside the valve core assembly to regulate the flow rate in the two pipes connected to the valve core assembly. The ventilation hole on the valve core assembly partially overlaps with the exhaust hole of the valve core. When the valve core is compressed and moves up and down, it can continuously overlap with the ventilation hole. When they overlap, an air exchange channel is formed, which carries away heat energy and creates a cooling effect.

[0010] 2. This utility model, through the corresponding arrangement of multiple exhaust holes and ventilation holes, ensures that the exhaust holes and ventilation holes always maintain a partial overlap during movement. This overlap forms an air channel, which exchanges heat energy and cools the valve core assembly and valve core during use. In addition, the use of multiple heat insulation strips better isolates the valve core assembly from the high temperature outside, ensuring a stable operating environment for the valve core assembly.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figures 1-3 The valve core assembly shown includes a connecting bolt 1, a valve core body 1 2, a valve core body 2 3, a valve core body 3 4, a valve core body 4 5, and a sealing ring 6. The connecting bolt 1 is threaded into the valve core body 1 2. The valve core body 2 3 is located at the bottom of the valve core body 1 2. The valve core body 3 4 is connected to the bottom of the valve core body 2 3. The valve core body 4 5 is located at the bottom of the valve core body 3 4. The sealing ring 6 is fitted at the bottom of the valve core body 4 5. Multiple first ventilation holes 301 are opened on the surface of the valve core body 2 3, and the first ventilation holes 301 are adapted to the first exhaust holes 302. The first exhaust holes 302 are opened on the movable sleeve 303. Second ventilation holes 501 are evenly opened on the valve core body 4 5, and the second ventilation holes 501 correspond to the second exhaust holes 502.

[0019] By utilizing the partial overlap of the first ventilation hole 301 and the first exhaust hole 302, when the moving sleeve 303 is compressed and moved, it can continuously overlap the first exhaust hole 302 and the first ventilation hole 301 to form an air exchange channel, which can exchange heat energy for the entire valve core assembly and play a role in cooling. The second ventilation hole 501 and the second exhaust hole 502 work in the same way.

[0020] Multiple second exhaust ports 502 are provided on the control valve core 503. The bottom of the control valve core 503 is a cylindrical protrusion, and an L-shaped exhaust channel 504 is provided inside the cylindrical protrusion. The cylindrical protrusion at the bottom of the control valve core 503 contacts the surface of the rubber valve 505, and the rubber valve 505 can extend out of the valve core body 503. The second exhaust ports 502 all penetrate the bottom of the control valve core 503, forming a cavity at the bottom of the control valve core 503. The size of the second exhaust port 502 is slightly smaller than that of the second vent 501. The first vent 301 also penetrates the bottom of the valve core body 503, and the size of the first vent 301 covers the displacement range of the first exhaust port 302.

[0021] A sliding member 201 is fitted inside the valve core body 1 2. The bottom of the sliding member 201 is fixedly connected to the top of the spring 1 202. The bottom of the spring 1 202 extends into the movable sleeve 303 and is fixedly connected to the conical valve core 304. The bottom of the conical valve core 304 is conical, and the bottom shape matches the bottom shape of the movable sleeve 303. A heat insulation cotton strip 403 is fitted at the bottom of the movable sleeve 303. The bottom of the movable sleeve 303 contacts the spring 2 402 that is slidably connected inside the movable sleeve 401. The spring 2 402 extends into the control valve core 503. The heat insulation cotton strip 403 is also fitted on the valve core body 3 4.

[0022] Working principle of this utility model:

[0023] Refer to the instruction manual appendix Figures 1-3 When using this utility model, first install the valve core assembly consisting of valve core body 1 2, valve core body 2 3, valve core body 3 4, and valve core body 4 5. It is often connected between liquid or gas pipelines. The flow rate of liquid or gas in the pipeline is controlled by controlling the pressure at the connecting bolt 1. Then install the connecting bolt 1 on the valve core assembly. The flow rate in the pipeline is controlled by rotating the connecting bolt 1.

[0024] Refer to the instruction manual appendix Figures 3-5 When using this utility model, the valve core assembly is opened and closed by the continuous up and down movement of the rubber valve 505, thereby increasing or decreasing the pressure in the pipes at both ends of the connection.

[0025] Under the elastic action of spring 202 and spring 402, the moving sleeve 303 and the control valve core 503 will move within the valve core assembly. During the movement, fresh air will be continuously drawn from the first ventilation hole 301 and the second ventilation hole 501 into the first exhaust hole 302 and the second exhaust hole 502, forming gas exchange in the cavity at the bottom of the valve core body 23 and the valve core body 45, which will produce a cooling effect on the valve core body 23 and the valve core body 45.

[0026] The heat insulation strips 403 installed on both valve core body 3 and valve core body 2 can also isolate the valve core assembly from the high temperature of the outside world during use, so that the performance of the valve core assembly will not be affected by the high temperature outside the valve core assembly or the high temperature inside the pipeline (because thermal expansion will increase friction).

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
