Description

Technical Field

[0001] The invention relates to a combined gas valve, in particular to a combined gas valve with multiple gas outlet channels. Background Art

[0002] A fireplace is a traditional heating device that is both safe and efficient. In addition to its heating function, a fireplace can also be used as a decorative item with good ornamental value. With the rapid changes in production and life, people's requirements for fireplaces are getting higher and higher. A new type of gas fireplace with multiple burners has also emerged. The gas valve used for this new type of gas fireplace requires multiple air outlets. In order to make the flame heights of multiple burners on the fireplace consistent at any time, the gas valve needs to synchronously adjust the flow of each air outlet when adjusting the air outlet flow. In addition, fireplaces often need to be used in the absence of city electricity, and the gas valve is also required to consume less power.

[0003] However, the flow regulation of multiple outlet channels of existing gas valves is generally performed by multiple sets of independent adjustment mechanisms, which rely on program settings to control the adjustment synchronization of multiple outlets. Multiple sets of independent mechanisms perform separately, which has a complex structure, increases costs, increases the number of driving components, and consumes a lot of power. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is to provide a combined gas valve with multiple gas outlet channels. The present invention can simultaneously adjust the gas outlet flow of multiple gas outlet channels of the gas valve through a driving element, and save power consumption by changing the different current sizes when the valve is opened and maintained.

[0006] (II) Technical solution

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a combined gas valve with multiple gas outlet channels, including a valve body, a solenoid valve and a flow regulating mechanism, the valve body includes an air inlet and multiple air outlets, at least two air outlet channels are formed between the multiple air outlets and the air inlet, and regulating ports are arranged in the at least two air outlet channels, the regulating ports are arranged around the flow regulating mechanism, and the flow regulating mechanism can simultaneously control the gas flow through each of the regulating ports. The synchronous regulation of the flow of each of the regulating ports refers to synchronous regulation according to a certain ratio or rule.

[0008] A valve sealing port is also provided on the valve body. The valve sealing port is provided behind the air inlet. The gas needs to pass through at least one valve sealing port from the air inlet to each of the air outlets.

[0009] The solenoid valve is provided with a sealing gasket, which cooperates with the valve sealing port. By controlling the disconnection and attraction of the solenoid valve, the sealing and opening of the air intake of the sealing gasket and the valve sealing port can be controlled.

[0010] The multiple air outlets are two or more air outlets.

[0011] In a further technical solution, on at least one of the air outlet channels, a low-grade air outlet channel is arranged in parallel with the adjusting port on the same air outlet channel, and a low-grade adjusting plug is arranged in the low-grade air outlet channel, and the low-grade adjusting plug is threadedly connected to the valve body, and the tail of the low-grade adjusting plug is provided with a certain shape, such as a slot or a hexagonal groove, etc., so that the depth of the low-grade adjusting plug screwed into the valve body can be manually adjusted by a certain tool to change the gas flow rate passing through the low-grade air outlet channel.

[0012] In a further technical solution, the flow regulating mechanism is provided with a push rod and a pressure plate, an adjusting rod is provided in the adjusting port, an adjusting rod pressure head is provided on the pressure plate at a position corresponding to at least one of the adjusting rods, the head of the adjusting rod pressure head is in contact with the tail of the adjusting rod, and a reset device is provided between the adjusting rod and the valve body, and the gas flow rates of each of the adjusting ports can be adjusted simultaneously by pushing the push rod.

[0013] In a further technical solution, the height of the head of the adjusting rod pressure head relative to the surface of the pressure plate can be adjusted to compensate for the inconsistent length of the adjusting rod caused by errors in the processing and manufacturing process.

[0014] In a further technical solution, the solenoid valve is an electromagnet structure with a double coil, which is composed of a solenoid valve static coil assembly and a solenoid valve moving coil assembly. The solenoid valve moving coil assembly is connected to the sealing gasket, and a solenoid valve spring is also arranged between the sealing gasket and the solenoid valve moving coil assembly. When the solenoid valve is turned from closed to open, a larger current is first passed through it, and after opening, a smaller current is passed through it to maintain the solenoid valve in an open state.

[0015] In a further technical solution, the solenoid valve may be one or more than one. By arranging and combining the solenoid valves in the valve body, combined control of opening and closing of air intakes of various air outlet channels in the valve body can be achieved.

[0016] In a further technical solution, a mother fire air outlet is also provided on the valve body, and there are two or more solenoid valves, which are divided into a main solenoid valve and at least one sub-solenoid valve. Correspondingly, there are two or more valve sealing ports on the valve body, which are respectively referred to as the main valve sealing port and the main valve sealing port and / or the auxiliary valve sealing port. The main solenoid valve controls the opening and closing of the main valve sealing port, and the sub-solenoid valve controls the opening and closing of the main valve sealing port and / or the auxiliary valve sealing port. Through the arrangement and combination of the sub-solenoid valves in the valve body, the combined control of the opening and closing of various air outlet channels in the valve body can be realized, and the mother fire air outlet is arranged after the main valve sealing port and before the main valve sealing port and / or the auxiliary valve sealing port.

Under the action of the resetting device 55, the openings formed by the head of the adjusting rod 53 and the first main adjusting port 110' and the second main adjusting port 110" are slowly reduced until they are closed, thereby adjusting the gas flow through the first main adjusting port 110' and the second main adjusting port 110".

[0079] like Figure 38-Figure 39As shown, in the present embodiment 3, a low-gear air outlet channel is respectively arranged in each air outlet channel, that is, on the first main air outlet channel 18′ and the second air outlet channel 18″, a first main low-gear air outlet channel 112′ and a second main low-gear air outlet channel 112″ are respectively arranged in parallel with the first main regulating port 110′ and the second main regulating port 110″, and each low-gear air outlet channel also includes a low-gear regulating plug, that is, a first main low-gear regulating plug 6′ and a second main low-gear regulating plug 6″, the first main low-gear regulating plug 6′ is arranged in the first main low-gear air outlet channel 112′, and the second main low-gear regulating plug 6″ is arranged in the second main low-gear air outlet channel 112″, and a first main low-gear regulating sealing ring 61′ and a second main low-gear regulating sealing ring 61″ are arranged on the first main low-gear regulating plug 6′ and the second main low-gear regulating plug 6″, which are respectively used for the first main low-gear regulating plug 6′, the second main low-gear regulating plug 6″ and the valve body 1.
