Description

Technical Field

[0001] This utility model relates to a gas valve body. Background Technology

[0002] Currently, gas valve bodies, as a key control component, are widely used in various gas appliances. Their airtightness directly affects the safety and reliability of the equipment. The ignition needle of the gas valve body needs to be installed through a frame, working in conjunction with the gas duct on the frame to supply gas for ignition. However, the frames currently on the market are generally located on the front side of the valve body near the top. The front side of the valve body usually has a gas outlet pipe for supplying gas to the burner. Therefore, to avoid structural interference between the frame and the gas outlet pipe, the valve body usually needs to be heightened, leading to increased material consumption. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned problems. We provide a gas valve body with a reasonable structural design that solves the problem of interference between the frame and the gas outlet rod structure.

[0004] To achieve the above objectives, this utility model provides a gas valve body, which includes a valve body, an ignition needle bracket on the left side of the valve body, a solenoid valve tube on the right side of the valve body, an outlet pipe on the front side of the valve body, a valve core cavity formed inside the valve body, an air inlet communicating with the valve core cavity at the bottom of the valve body, the valve core cavity communicating with the solenoid valve tube through a first air pipe, the solenoid valve tube communicating with the outlet pipe through a second air pipe, the ignition needle bracket including a frame and an ignition needle, an air passage on the frame, the ignition needle being mounted on the frame and positioned near the outlet end of the air passage, and the inlet end of the air passage communicating with the valve core cavity through a third air pipe.

[0005] In one or more embodiments, the third air tube and the valve body are an integral structure, the frame has a sleeve portion that is fitted onto the third air tube, the sleeve portion is fixed onto the third air tube by screws, and the side of the third air tube has an air outlet corresponding to the air inlet end of the air passage.

[0006] In one or more embodiments, the air duct has an air inlet on the side corresponding to the ignition needle.

[0007] In one or more embodiments, an air inlet is provided at the connection between the air outlet pipe and the valve body, and multiple air inlet holes are distributed on the side of the air inlet.

[0008] In one or more embodiments, the air inlet has a recessed area, a threaded connection hole is provided on the periphery of the air inlet, and the air inlet is located at the bottom of the valve body.

[0009] In one or more embodiments, the valve core cavity is provided with a valve core for distributing gas, and a valve core rod is provided on the front side of the valve body. The valve core rod is connected to the valve core to drive the valve core to rotate.

[0010] Compared with the prior art, the advantages of this invention are: by placing the ignition needle bracket on the left side of the valve body and directly connecting the third gas pipe supplying it to the valve core cavity, this invention cleverly avoids the gas outlet pipe located on the front side of the valve body. This layout fundamentally solves the problem of spatial interference between the ignition needle bracket and the gas outlet pipe in traditional designs, thus eliminating the need to increase the overall height of the valve body to avoid this interference.

[0012] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0013] See appendix Figure 1-3 This application provides a gas valve body, characterized in that: it includes a valve body 1, an ignition needle bracket 2 is provided on the left side of the valve body 1, an electromagnetic valve tube 3 is provided on the right side of the valve body 1, an outlet pipe 4 is provided on the front side of the valve body 1, a valve core cavity is formed inside the valve body 1, an air inlet 5 communicating with the valve core cavity is provided at the bottom of the valve body 1, the valve core cavity is connected to the electromagnetic valve tube 3 through a first air pipe 6, the electromagnetic valve tube 3 is connected to the outlet pipe 4 through a second air pipe 7, the ignition needle bracket 2 includes a frame 21 and an ignition needle 22, the frame 21 is provided with an air passage 8, the ignition needle 22 is installed on the frame 21 and is set near the outlet end of the air passage 8, the inlet end of the air passage 8 is connected to the valve core cavity through a third air pipe 9, by setting the ignition needle bracket on the left side of the valve body 1 and directly connecting the third air pipe 9 supplying it to the valve core cavity, the outlet pipe 4 located on the front side of the valve body 1 is avoided. This layout fundamentally solves the problem of spatial interference between the ignition needle bracket 2 and the exhaust pipe 4 in traditional designs, thus eliminating the need to increase the overall height of the valve body 1 to avoid this interference. This directly reduces the overall height of the valve body, saves material costs, and simplifies the structural design of the valve body.

[0014] The third gas pipe 9 and the valve body 1 are an integral structure. The frame 21 has a sleeve part 221 that is fitted onto the third gas pipe 9. The sleeve part 221 is fixed to the third gas pipe 9 by screws 10. The side of the third gas pipe 9 has an outlet corresponding to the gas inlet end of the gas passage. This design improves the overall integrity and connection reliability of the structure and reduces leakage points. The design of the sleeve part makes installation and alignment more convenient, while the side outlet ensures that the gas can accurately and smoothly enter the gas passage of the ignition needle bracket, ensuring the reliability of ignition.

[0015] The gas passage 8 has an air inlet 11 on the side corresponding to the ignition needle 22, which introduces secondary air. This helps the gas to be more fully premixed with air at the ignition outlet, thereby improving ignition conditions and increasing ignition success rate and combustion efficiency.

[0016] An air inlet 12 is provided at the connection between the gas outlet pipe 4 and the valve body 1. Multiple air inlet holes 13 are distributed on the side of the air inlet 12. The air inlet holes can introduce air into the main gas supply passage to achieve pre-mixing of gas and air. This structure helps the gas to achieve more complete and stable combustion when it reaches the burner head, improves combustion efficiency and may reduce pollutant emissions.

[0017] The air inlet 5 is provided with a recessed part 14. The recessed part 13 can be used with a sealing ring to improve the sealing performance. The air inlet 5 is provided with a threaded connection hole 15 on its periphery. The air inlet 5 is located at the bottom of the valve body 1. The threaded connection hole 15 on the periphery provides a stable installation interface and enhances the airtightness of the connection.

[0018] The valve core cavity is equipped with a valve core for distributing gas. A valve core rod 16 is provided on the front side of the valve body 1. The valve core rod 16 is connected to the valve core to drive the valve core to rotate, so that the user can control the gas delivery amount by operating the valve core rod 16.

[0019] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments.
