Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubrication system technology, and in particular to a dual-material heating nozzle. Background Technology
[0002] Heated nozzles have significant application value in the lubrication industry, especially for lubrication needs under low temperature, high viscosity, or special operating conditions. In industrial equipment lubrication scenarios, lubricating oils / greases are prone to problems such as increased viscosity and decreased fluidity at low temperatures. Traditional lubrication systems are prone to pipe blockage or uneven spraying, which has many adverse effects on subsequent lubrication.
[0003] Normally, the lubricating medium is preheated at the source. However, as the lubricating medium enters the nozzle through the pipeline, the temperature is gradually lost along the pipeline, and the temperature reaching the nozzle is insufficient to improve its flowability and viscosity. If the temperature is increased to compensate for the lost temperature, it will affect the performance and stability of the lubricating medium itself to some extent, greatly reducing the lubrication effect. Utility Model Content
[0004] The purpose of this invention is to solve the problems of existing nozzles being prone to clogging, uneven spraying, and poor lubrication in low-temperature environments. It provides a dual-material heating nozzle that can heat the lubricating medium to the optimal working temperature, significantly reducing its viscosity and improving the fluidity and uniformity of the lubricant spraying.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dual-mass heating nozzle includes a dual-mass valve block assembly and a heating valve block assembly connected side by side. The dual-mass valve block assembly has a gas pipeline and a liquid pipeline inside. The inlet end of the gas pipeline is connected to a gas one-way valve assembly, and the inlet end of the liquid pipeline is connected to a liquid one-way valve assembly. A mixing pipeline is connected between the gas pipeline and the liquid pipeline. The outlet end of the mixing pipeline is connected to a right-angle connector. The right-angle connector is then connected to the nozzle through a connector. A spiral plug is screwed into the nozzle to form a spiral mist that is sprayed out from the nozzle.
[0007] The heating valve block assembly has a heating valve block with a single-head mold electric heating tube, a temperature control switch and a temperature fuse that work together. The heating valve block has an annular groove on the side facing the dual valve block, and an O-ring is embedded in the annular groove. The back of the heating valve block is connected to a circular DIN socket, which is electrically connected to the single-head mold electric heating tube, the temperature control switch and the temperature fuse.
[0008] Furthermore, the gas check valve assembly and the liquid check valve assembly are located on the left side of the dual-mass valve block. The check valve assembly and the dual-mass valve block are connected by threads and a copper gasket is provided between them for sealing the left end face by pressing the copper gasket.
[0009] Furthermore, the gas pipeline and the liquid pipeline are arranged in parallel to each other, and their right ends are respectively connected to hexagonal socket plugs. The hexagonal socket plugs are connected to the right side of the dual-material valve block by threads, and a copper gasket is provided between them to press the copper gasket to seal the right end face.

[0011] Furthermore, thread sealant is applied to the right-angle connector, the connecting body, and the nozzle. The right-angle connector mates with the lower part of the dual-mass valve block and the two are connected by threads. The connecting body and the right-angle connector are also connected by threads. The nozzle and the connecting body are also connected by threads. The spiral plug is located in the inner cavity of the nozzle and forms an interference fit with the inner cavity of the nozzle.

The lower part of the single-head mold electric heating tube is provided with a screw plug, which is also coated with thread sealant and is connected to the lower part of the heating valve block by a thread.
[0013] Furthermore, the temperature control switch is embedded in the temperature control switch mounting base, which is connected to two clamping screws. The sensing surface of the temperature control switch is in close contact with the heating valve block for real-time sensing of the heating temperature.
[0014] Furthermore, the circular DIN socket is coated with thread sealant and connected to the back of the heating valve block via threads. The circular DIN socket includes points 1, 2, 3, and PE. One end of the single-head mold electric heating tube is soldered to point 1, and the other end is pressed onto spring 1 with a high-temperature resistant soft silicone wire 1.

[0035] The outlet end of the mixing pipeline 16 is connected to a right-angle connector 17, which is then connected to the nozzle 19 via a connector 18. Thread sealant is applied to the right-angle connector 17, connector 18, and nozzle 19. The right-angle connector 17 mates with the lower part of the dual valve block 11 and the two are connected by threads. The connector 18 is also connected to the right-angle connector 17 by threads, and the nozzle 19 is also connected to the connector 18 by threads.
[0036] A spiral plug 191 is screwed into the nozzle 19, and the spiral plug 191 and the inner cavity of the nozzle 19 form an interference fit.
[0037] See Figure 2 , Figures 5-8The heating valve block 21 of the heating valve block assembly 2 is equipped with a single-head mold electric heating tube 22, a temperature control switch 23 and a temperature fuse 24 that cooperate with each other. The heating valve block 21 has an annular groove 2a on the side facing the dual valve block 11. An O-ring 25 is embedded in the annular groove 2a. A circular DIN socket 26 is connected to the back of the heating valve block 21. The circular DIN socket 26 is connected to the single-head mold electric heating tube 22, the temperature control switch 23 and the temperature fuse 24 through electrical connections.
[0038] The upper part of the heating valve block 21 is connected to the internal hexagonal flat end set screw 27 by a thread, and the internal hexagonal flat end set screw 27 is coated with thread sealant. The lower end of the internal hexagonal flat end set screw 27 is directly facing the single-head mold electric heating tube 22. The lower part of the single-head mold electric heating tube 22 is provided with a screw plug 28, which is also coated with thread sealant and is connected to the lower part of the heating valve block 21 by a thread.
[0039] The temperature control switch 23 is embedded in the temperature control switch mounting base 29, which is connected to two clamping screws 210. The sensing surface of the temperature control switch 23 is in close contact with the heating valve block 21 for real-time sensing of the heating temperature.

[0044] Regarding the dual-material valve block: When the oil circuit and the gas circuit are connected to the check valve, the two substances are mixed in the dual-material valve block to form an aerosol state. The aerosol is then transmitted from the dual-material valve block through the right-angle connector 17 and the connector 18 to the spiral plug 191. The aerosol is then sprayed out from the nozzle 19 through the spiral pipe of the spiral plug 191.

The heating nozzle adopts a main body separation assembly, which makes the composition simpler and the later replacement and maintenance more convenient and efficient. The addition of a fuse in the circuit improves the safety and reliability of the product.
