Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to a gas flow control valve of a double-cylinder engine. Background Art

[0002] A two-cylinder engine refers to an engine with two cylinders. It is composed of two identical single-cylinders arranged in a body and sharing a crankshaft to output power.

[0003] The gas control valve of the twin-cylinder engine currently on the market is a split type, and a tee and a plurality of gas hoses are usually required to connect the gas control valve and the engine, and the gas is delivered to the two cylinders of the twin-cylinder gas engine through the gas hoses.

[0004] There are some problems when using the existing gas control valve. Since the gas control valve is connected to the engine through a gas hose, the gas hose is prone to interfere with other adjacent components and bends. The gas flow at the bend changes, resulting in gas flow loss. Utility Model Content

[0005] The utility model aims to provide a gas flow control valve for a twin-cylinder engine, aiming to solve the problem that the existing twin-cylinder engine gas control valve is prone to gas flow loss.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A gas flow control valve for a twin-cylinder engine comprises a valve body, a connecting seat and a mounting seat, wherein the valve body is provided with two gas passages, wherein solenoid valves are installed in the gas passages, wherein the connecting seat is provided with two first air intake passages, wherein one end of the two first air intake passages for intake is respectively connected with one end of the two gas passages for exhaust, and the mounting seat is provided with two air intake holes respectively connected with the two first air intake passages, wherein one end of the air intake hole away from the first air intake passage is connected with a rigid air intake pipe.

[0008] By adopting the above scheme, when in use, two rigid intake pipes are respectively fixed on the two cylinders of the two-cylinder engine, the intake pipes are connected to the corresponding cylinders, and the gas flow in the gas channel is controlled by the solenoid valve. First, since the intake pipe is rigid, the intake pipe will not bend during use, so as to avoid the situation where the bending of the intake pipe affects the gas flow, thereby improving the stability of gas delivery. Secondly, the gas flow control valve is directly integrated into the two-cylinder engine, shortening the gas pipeline, improving the integrity, saving installation space, and facilitating assembly and consistency management. In addition, the rigid intake pipe and the mounting seat together form a bracket to support the control valve, providing an installation position for the control valve on the two-cylinder engine.

[0009] The utility model is further configured that the air intake pipe and the mounting seat are integrally formed. Since the air intake pipe and the mounting seat are integrally formed, the overall stability is improved and the assembly steps are reduced.

[0010] The utility model is further configured that the mounting seat and the air intake pipe are both made of metal material. Since the metal material has strong rigidity and stability, the stability of the air intake pipe is ensured.

[0011] The utility model is further configured such that a reinforcing rib is fixedly connected between the two intake pipes. Since the two intake pipes are in an eight-shaped shape, the upper end of the intake pipe needs to bear the gravity of the connecting seat, the valve body, the solenoid valve and other components, which makes the connection between the intake pipe and the connecting seat subject to greater stress and easy to be damaged. The reinforcing rib connected between the two intake pipes can reduce the stress at the connection between the intake pipe and the connecting seat, thereby improving the stability of the connection between the intake pipe and the connecting seat.

[0012] The utility model is further configured that the reinforcing rib is integrally formed with the two air intake pipes. Since the reinforcing rib is integrally formed with the air intake pipes, the overall stability of the air intake pipes is enhanced and the processing steps of the air intake pipes are reduced.

[0013] The utility model is further configured that one end of the two gas channels for gas inlet is commonly connected with an air inlet nozzle, through which the gas pipeline can be conveniently connected.

[0014] The utility model is further configured that a pressure sensor is installed in the gas channel located on the left or right side. The gas pressure in the gas channel can be conveniently monitored by the pressure sensor.

[0015] The utility model is further configured that two solenoid valves are installed at intervals along the length direction of the gas channel. The gas flow in the gas channel can be controlled more accurately by the two solenoid valves.

[0016] The utility model is further configured such that the side of the connection seat is further provided with a second air intake channel corresponding to the two first air intake channels one by one, and the second air intake channel is connected to the corresponding first air intake channel. The second air intake channel can be conveniently connected to the throttle valve body, and the throttle valve body can be integrated into the connection seat, further improving the integration effect.

[0017] The utility model is further configured that at least two connectors are integrally formed at one end of the intake pipe away from the mounting seat, and bolt connection holes are provided on the connectors. Through the bolt connection holes on the connectors, the intake pipe can be conveniently connected to the twin-cylinder engine by bolts, thereby facilitating installation and removal.

[0018] In summary, the gas flow control valve for a dual-cylinder engine provided by the utility model has at least the following beneficial effects:

[0019] 1. The air intake pipe will not bend during use, which improves the stability of gas delivery.

[0020] 2. The gas flow control valve is integrated into the twin-cylinder engine, which improves the integrity and saves installation space. BRIEF DESCRIPTION OF THE DRAWINGS
