Problems solved by technology

However, the sealing structure is easy to age, so the safety is poor
The problems easily caused by the air intake from the bottom of the valve core are: 1. The gas flow to the main fire vent hole and the secondary fire vent hole will be uneven, so that the main fire and the secondary fire cannot be adjusted at the same time; 2. The safety is poor, and the fire intensity is different. controlled

Embodiment Construction

[0032] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0033] Combine below Figure 1 to Figure 11 The technical solution provided by the present invention is described in more detail.

[0034] A plug valve, such as Figure 1-Figure 11 As shown, it includes: a valve body 100, a valve core 200, a solenoid valve 233, a knob rod 300, a flow adjusting nail 400, and a bottom cover 500.

[0035] The valve body 100 is provided with an intake passage 110, a main fire passage 120 and a secondary fire passage 130. Specifically, the main fire passage 120 and the secondary fire passage 130 are arranged on the same side of the valve body 100 in parallel, and the air inlet passage 110 is arranged on the other side of the valve body 100. In this embodiment, the air intake passage 110 is taken as the hor...

Abstract

The invention provides a plug valve, and relates to the technical field of gas stove accessories. The plug valve comprises a valve body and a valve element, wherein the valve body is provided with a gas inlet channel, a main fire channel and a secondary fire channel; the valve element is installed in the valve body, the valve element can rotate relative to the valve body, a valve cavity is formedin the valve element in a penetrating mode, and vent holes which are blocked from the valve cavity is formed in the outer peripheral wall of the valve element; the vent holes comprise a gas inlet communicating with the gas inlet channel, a main fire gas outlet hole communicating with the main fire channel and a secondary fire gas outlet hole communicating with the secondary fire channel; a gas guide groove which is blocked from the valve cavity is further formed in the outer peripheral wall of the valve element; and the gas inlet, the main fire gas outlet hole and the secondary fire gas outlethole communicate with the gas guide groove. Through the arrangement and the guide effect of the gas guide groove, gas is averagely divided, so that the gas flow in the main fire channel is the same as the gas flow in the secondary fire channel; and the gas inlet, the main fire gas outlet hole, the secondary fire gas outlet hole and the gas guide groove are blocked from the valve cavity, so that the problem that the gas flows into the valve cavity from the bottom of the valve cavity is solved, and the safety is improved.

Description

Technical field [0001] The invention belongs to the technical field of gas stove accessories and relates to a plug valve. Background technique [0002] The cock valve of a gas stove is the core component of a household gas stove. The existing mechanical gas stoves are all ignited, adjusted firepower, and extinguished through the cock valve. [0003] Household gas stoves generally have an inner ring fire and an outer ring fire. A common dual-channel gas valve generally includes a valve body with an air inlet channel, a main fire gas outlet channel, and a secondary fire gas outlet channel. The valve body is equipped with a rotatable valve core. The upper part of the valve core has a spring cavity, and the lower part of the valve core is provided with a venting chamber. The valve body is equipped with a valve stem that can drive the valve core to rotate. The lower end of the valve stem holds the valve stem to keep moving upward and disconnect from the valve core. The spring is locate...
