Inner and outer ring flow gas adjusting valve

Abstract

Disclosed is an inner and outer ring flow gas adjusting valve. The inner and outer ring flow gas adjusting valve comprises a valve body, a valve core, an electromagnetic valve, an ejector rod, a valveneedle and a valve rod, and is characterized in that the valve core comprises a core shell and a sleeve, the core shell is hollow in the axial direction, a ring of first outer ventilating holes whichare matched with an inner ring gas outlet channel to adjust the gas outlet flow are formed in the upper end of the side wall, and a ring of second outer ventilating holes which are matched with an outer ring gas outlet channel to adjust the gas outlet flow are formed in the lower end of the side wall; and the sleeve is hollow in the axial direction and is arranged in an inner cavity of the core shell in a sealing mode, a ring of first inner ventilating holes corresponding to the first outer ventilating holes are formed in the upper end of the side wall of the sleeve, a ring of second inner ventilating holes corresponding to the second outer ventilating holes are formed in the lower end of the side wall, and the valve needle is arranged in the sleeve in a penetrating mode. The valve core is formed by assembling the split core shell and the sleeve, a first connecting hole and a second connecting hole are not interfered by sealing grease, and accurate control of firepower is achieved onthe premise that fire holes are unblocked.

Description

technical field [0001] The invention relates to a valve, in particular to a valve applied to a gas cooker. Background technique [0002] Gas valves in various gas cookers are manually operated valves that control the supply of gas sources. 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, an inner ring outlet channel and an outer ring outlet channel. The valve body is provided with a rotatable valve core. The lower part of the valve core is provided with a vent chamber, the valve body is pierced with a valve stem that can drive the valve core to rotate, and the valve stem can drive the valve core to rotate together. A series of adjusting fire holes of different sizes in the air outlet channel, and an arc-shaped inner ring fire hole for connecting the air intake channel and the inner ring air outlet channel. [0003] When in use, the ends of the inner rin...

AI Technical Summary

Problems solved by technology

[0005] When the user uses it, many of the existing gas valves have a firepower that changes too quickly, and it is not easy to adjust the firepower required by the user

The matching of the inner and outer rings of firepower is not good, and users cannot adjust the firepower they need

There is no memory feel during the firepower adjustment process, and the firepower that the user wants cannot be quickly adjusted at the first time, etc.

In addition, the throttling hole is directly punched on the valve core. Since there is sealing grease between the valve core and the valve body, if the hole diameter of the side wall of the valve core is small, it is easy to be blocked by the sealing grease during the rotation of the valve core. , the multi-section valve is easy to block; the aperture of the hole on the side wall of the valve core is not easy to control, resulting in inaccurate control of the firepower
