Description

Cock valve ventilation structure and cooking utensils

Technical Field

The utility model relates to a plug valve ventilation structure and cooking utensils.

Background

The stove is an essential kitchen utensil for daily life of people, wherein the plug valve is an important accessory of the stove, when the plug valve is produced in a factory, an outer air pipe and a central air pipe are on the same plane, but an air inlet of the outer air pipe and an air inlet of the central air pipe are not on the same horizontal plane, so that a hole is obliquely drilled at the bottom end of a valve core cavity to be communicated with the central air pipe after a worker drills a hole in the central air pipe but does not communicate with the valve core cavity, and due to different proficiency degrees of workers and different operation modes, the distance and the position of the central air inlet from the bottom end of the valve core cavity are different, so that the small contact area between the partial area and the valve core generates air leakage, and the too short contact area is easy to cause air leakage with the.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the weak point in the prior art, provide a plug valve ventilation structure, aim at central air inlet position of punching, avoid mixing of gases and gas leakage.

In order to achieve the above purpose, the utility model adopts the following scheme:

the utility model provides a plug valve ventilation structure, includes disk seat and case, be provided with the case chamber on the disk seat, the case sets up at the case intracavity, and first trachea and second trachea are connected to the case chamber, case intracavity is provided with first air inlet and second air inlet, first trachea is provided with outlet duct and breather pipe, breather pipe intercommunication first air inlet and outlet duct, first air inlet is on the length extension line of breather pipe, the second air inlet is earlier at the length extension of second intake pipe, first air inlet and second air inlet are not on same horizontal plane.

In one or more embodiments, the ventilation pipe and the second air pipe are not on the same horizontal plane, and the air outlet pipe and the second air pipe are on the same horizontal plane.

In one or more embodiments, the level of the air duct is lower than the level of the second air duct, and the level of the first air inlet is lower than the level of the second air inlet.

In one or more embodiments, the distance between the lower end openings of the first air inlet valve core cavity is greater than 3 mm.

A stove comprises the plug valve ventilation structure.

Has the advantages that: the utility model provides a plug valve ventilation structure and cooking utensils, the breather pipe through forming the slope is convenient for the workman and can form first air inlet along breather pipe drilling intercommunication case chamber, simultaneously along second intake pipe drilling intercommunication case chamber formation second air inlet for production is convenient fast, avoided drilling to the tracheal operation of outer loop at case chamber lower extreme opening simultaneously, make the rigidity of first air inlet, the same standardized production of formation in production position, and first air inlet position is controllable, can avoid the cross gas and leak gas.

Detailed Description

The application scheme is further described below with reference to the accompanying drawings:

example (b):

referring to fig. 1-3, a plug valve ventilation structure includes a valve seat 1, a valve stem 2 and a valve core 3, the valve seat 1 is provided with a valve core cavity 15, the valve core 3 is disposed in the valve core cavity 15, the valve stem 2 is disposed above the valve core cavity 15 and drives the valve core 3 to rotate, the valve core cavity 15 is connected to a first air pipe 11 and a second air pipe 12, the valve core cavity 15 is provided with a first air inlet 13 and a second air inlet 14, the first air pipe 11 is provided with an air outlet pipe 111 and a vent pipe 112, the vent pipe 112 is communicated with the first air inlet 13 and the air outlet pipe 111, the first air inlet 13 is on a length extension line of the vent pipe 112, the second air inlet 14 is communicated with the second air pipe 12 and is on a length extension line of the second air pipe 12, the first air inlet 13 and the second air inlet 14 are not on the same horizontal plane, the vent pipe 112 and the second air pipe, the air outlet pipe 111 and the second air pipe 12 are on the same horizontal plane, so that the air pipe 112 is obliquely arranged, the horizontal height of the air pipe 112 is lower than that of the second air pipe 12, the horizontal height of the first air inlet 13 is lower than that of the second air inlet 14, and the distance H between the first air inlet 13 and the lower end opening of the valve core cavity 15 is greater than 3 mm.

Because the horizontal heights of the vent pipe 112 and the second air pipe 12 are different, and the vent pipe 112 is obliquely arranged, when a worker operates, the worker only needs to drill holes along the length directions of the length of the vent pipe 112 and the length of the second air pipe 12 to be communicated with the valve core cavity 15 to form the first air inlet 13 and the second air inlet 14 with different horizontal heights, the operation of drilling holes from the bottom end of the valve core cavity 15 is reduced in production, meanwhile, the holes are drilled along the length directions of the vent pipe 112 and the second air pipe 12, the directions are fixed, and the operation is convenient and simple.

A cooker comprises the plug valve ventilation structure, wherein the plug valve ventilation structure and the connection structure of the cooker are consistent with those of a common plug valve and the cooker, and are not shown in the drawing.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
