Description

Technical Field

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

[0002] The existing technology, Chinese Patent 202120855217.6, describes a gas proportional valve, including a proportional regulating valve assembly and a gas outlet shut-off valve assembly. The proportional regulating valve assembly includes a proportional regulating valve body, an iron core with a coil sleeved on it, a proportional regulating valve core, and an elastic element. The proportional regulating valve body includes a pressure-stabilizing chamber with a gas inlet and a proportional regulating valve port; the iron core is fixed to the outer surface of the proportional regulating valve body; the proportional regulating valve core and the elastic element are configured such that: when the coil is de-energized, the proportional regulating valve core is pressed into the pressure-stabilizing chamber by the elastic element, blocking the proportional regulating valve port; when the coil is energized, it is attracted by the iron core and opens the proportional regulating valve port, allowing the pressure-stabilizing chamber and the gas outlet shut-off valve assembly to connect. This invention reduces the reaction time of the proportional regulating valve assembly and improves the sensitivity of the proportional valve. The problem is that adjusting the iron core requires a wrench and nut, and a screwdriver and tool slot at the end of the iron core, making adjustment inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a gas proportional valve that is easy to adjust, and it features a simple structure and convenient debugging.

[0004] This utility model is implemented as follows: a gas proportional valve that is easy to adjust includes a valve body, a coil frame, an iron core, a coil and a bracket. The coil frame includes a conduit and end plates located at both ends. The iron core includes an external thread and a tool groove at one end. Its special feature is that the bracket includes a seat plate and several seat frames. The seat plate is provided with a punched flange, and the punched flange is provided with an internal thread. The iron core is provided with an annular groove. It also includes sealing rings, The sealing ring is located in the annular groove, and the iron core and the sealing ring are located inside the conduit. The external thread of the iron core is screwed into the internal thread.

[0005] The gas proportional valve that is easy to adjust is characterized in that the tool slot is cross-shaped.

[0006] The aforementioned conveniently adjustable gas proportional valve is characterized in that: a fixed column seat is provided on the valve body. The frame is equipped with fixed feet; The fixed column base supports the fixed foot plate and is fixed with screws.

[0007] The gas proportional valve that is easy to adjust is characterized in that the bracket is made of a single piece of metal sheet.

[0008] This utility model discloses a gas proportional valve that is easy to adjust. The bracket is provided with punched flanges and internal threads. During adjustment, only a screwdriver is needed to rotate the iron core. The operation and adjustment are convenient and the structure is simple. Attached Figure Description

[0012] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] like Figure 1 , Figure 2 The present invention relates to a gas proportional valve that is easy to adjust, comprising a valve body 1, a coil frame 2, an iron core 3, a coil 4, and a bracket 5. The coil frame 2 includes a conduit 21 and annular end plates 22 located at both ends. The iron core 3 includes an external thread 31 and a tool groove 32 at one end. The bracket 5 includes a seat plate 51 and several seat brackets 52. The seat plate is provided with a punched flange 53, and the punched flange 53 is provided with an internal thread. The iron core 3 is provided with an annular groove 33. It also includes sealing ring 6, The sealing ring 6 is located within the annular groove 33, and the iron core 3 and the sealing ring 6 are located within the conduit 21. The external thread 31 of the iron core 3 engages with the internal thread of the punched flange 33. The sealing ring 6 serves as a buffer and prevents loosening. With this structure, during adjustment, only a screwdriver is needed to rotate the iron core 3, making adjustment convenient.

[0015] The tool slot 32 is cross-shaped.

[0016] As a further improvement of this utility model: the valve body 1 is provided with a fixed column seat 11. The seat frame 52 is provided with a fixed foot plate 521; The fixed column base 11 supports the fixed foot plate 521 and is fixed with screws.

[0017] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
