[0005] The valve body has an air cavity inside, and an adjustment hole is provided on the valve body. An adjustment screw that can be tightened or loosened is matched on the adjustment hole. The air pressure inside the air cavity is changed by changing the adjustment hole space with the adjustment screw. The valve body is also provided with an ignition tube interface that matches the electronic ignition ignition tube, and the ignition tube interface is connected to the adjustment hole and the air cavity.

[0006] A further implementation scheme of the utility model is that a rubber ring is sleeved on the adjusting screw, and the rubber ring abuts against the outer end surface of the adjusting hole.

[0007] A further implementation scheme of the utility model is that the axis of the adjustment hole is perpendicular to the axis of the ignition tube interface.

[0008] A further implementation scheme of the utility model is that the valve body is also provided with an air inlet, the air inlet is connected to the nozzle, and a plurality of branch holes are opened along the circumferential direction on one end of the nozzle that is connected to the air inlet.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] When the medium-pressure valve structure is in use, the electronic ignition ignition tube is connected to the ignition tube interface. By adjusting the depth of the adjusting screw inserted into the valve body, the internal space of the adjusting hole is changed, so that the internal space of the air cavity is changed to adjust the internal air pressure. After the internal air pressure of the air cavity is enhanced, it is easier to ignite.

[0011] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0015] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end.

[0017] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Such as Figure 1 and Figure 2 The present invention provides a new type of adjustable ignition pressure valve body structure, including:

[0019] The valve body 1 has an air cavity 2 inside. An adjustment hole 3 is provided on the valve body 1, and an adjustable screw 15 that can be tightened or loosened is arranged in a matching manner on the adjustment hole 3. A rubber ring is sleeved on the adjustable screw 15, and the rubber ring abuts against the outer end face of the adjustment hole 3 to improve airtightness.

[0020] The space of the adjusting hole 3 is changed by adjusting the screw 15 to change the air pressure inside the air cavity 2. The valve body 1 is also provided with an ignition tube interface 4 which is connected and matched with the electronic ignition ignition tube. The axis of the adjusting hole 3 is perpendicular to the axis of the ignition tube interface 4. The ignition tube interface 4 is internally connected to the adjusting hole 3 and the air cavity 2. When in use, tighten the adjusting screw. At this time, the internal space of the adjusting hole 3 becomes smaller, and the overall space of the air cavity 2 becomes smaller, so that the internal air pressure becomes larger and the gas concentration is high, so that it is easier to ignite.

[0021] Furthermore, the valve body 1 is provided with an air inlet 5, which is connected to a nozzle 6. A plurality of branch holes 60 are provided along the circumferential direction on one end of the nozzle 6 that is connected to the air inlet 5. The branch holes 60 allow for more sufficient air intake, more complete combustion of the gas, and reduced red flame phenomenon.

[0022] Secondly, the valve body 1 is also provided with a valve port 7, a lower sealing ring 8 is arranged in the valve port 7, two spaced rubber pads 9 and a sealing pad 10 are arranged on the lower sealing ring 8, a ball 11 is arranged between the rubber pad 9 and the sealing pad 10, a spring 12 is arranged above the rubber pad 9, a valve cover 13 is screwed on the valve port 7, the bottom of the valve cover 13 is against the upper end of the spring 12, an upper sealing ring 14 is sealingly arranged between the valve cover 13 and the inner wall of the valve port 7, the upper sealing ring 14 and the lower sealing ring 8 are both O-rings, and a compression seal is formed between the ball 11, the sealing pad 10, the valve body 1 and the lower sealing ring 8, a spring 12 is added, and the pressure of the spring 12 is used to press the rubber pad 9, the rubber pad 9 presses the ball 11, and the ball 11 presses the sealing pad 10. After the sealing pad 10 is worn, the ball 11 will move toward the sealing pad 10 under the action of the spring 12, automatically compensate for the wear of the sealing pad 10, achieve a nearly constant tight pressure, and fully contact the sealing surfaces to improve the sealing performance.

[0023] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
