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 and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, 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 regulating nail 400 , and a bottom cover 500 .

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

Abstract

The invention provides a plug valve and relates to the technical field of gas stove accessories. The plug valve includes: a valve body, which is provided with an air inlet passage, a main fire passage and a secondary fire passage; The outer peripheral wall is provided with a vent hole blocked from the valve chamber, and the vent port includes: an air inlet connected to the air intake passage, a main fire outlet connected to the main fire passage, and a secondary fire outlet connected to the secondary fire passage. air hole; the outer peripheral wall of the valve core is also provided with an air guide groove blocked from the valve cavity; the air inlet, the main fire air outlet, and the secondary fire air outlet are respectively communicated with the air guide groove. Through the above setting, through the guiding effect of the air guide groove, the gas flow is evenly divided, so the gas flow in the main fire channel and the secondary fire channel are the same. Because the air inlet, the main fire outlet, the secondary fire outlet, and the air guide groove are all blocked from the valve cavity, there will be no problem of gas flowing in from the bottom of the valve cavity, which improves safety.

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 gas stove cock valve is the core component of the household gas stove, and the existing mechanical gas stoves are all ignited, adjusted firepower and flameout through the cock valve. [0003] Household gas cookers 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 outlet channel, and a secondary fire outlet channel inside. The valve body is provided with a rotatable valve core. The upper part of the valve core has a spring cavity, the lower part of the valve core is provided with a venting cavity, the valve body is pierced with a valve stem that can drive the valve core to rotate, and the lower end of the valve stem is held to keep the valve stem moving up and out of the connection with the valve core. The sprin...
