Abstract
The utility model relates to a coal-gas throttle valve which belongs to the technical field of energy-saving device structure. The coal-gas throttle valve is characterized by comprising a valve body arranged on a cooking utensil through a flange; the top end of the valve body is closed; the other end penetrates from the core of the valve; the middle part of the valve body is provided with a cavity provided with the core of the valve; the inside of the cavity is provided with spaced seal rings along the periphery of the core of the valve from the closed end to the lower part; the seal rings divide the cavity into an upper cavity and a lower cavity; the seal rings and the core of the valve are tightly combined; the two seal rings are provided with a check ring sleeve for fixing and sealing; the two sides of the valve body are respectively provided with an air inlet channel and an air outlet channel which are communicated with the upper cavity and the lower cavity and are connected with the inside of an air pipeline; one side of the core of the valve penetrating the valve body is connected with an external handle; the center of the other side of the core of the valve is inwards provided with a through cavity; the other end of the through cavity is accessed to the lower cavity communicated with the air outlet channel. The utility model has a simple structure, is safe and reliable to be operated, saves time and labor, saves energy and reduces consumption.
Description
One, technical field
The utility model relates to a kind of coal gas air throttle, belongs to the energy-saving equipment technical field of structures.
Two, background technique
At present, we are the manual rotary valve door with valve by daily being seen kitchen range, when opening and closing, all must tighten by means of the strength of hand, but in actual mechanical process, such as the master worker who is cooking, often both hands all have no time to spare throttle down, Deng just can close after hours in the hand, there is a part of combustion gas loss during this, caused certain energy waste, also the food duration and degree of heating in the kitchen range is had certain influence simultaneously.
Three, summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and a kind of easy and simple to handle, safe and reliable, plug-type air throttle that can reach throttle down under the unserviceable situation of both hands with the body part touching is provided.
A kind of coal gas air throttle of the present utility model, special way is
Comprise by flange plate 5 being installed on valve body 4 on the kitchen range, the top closure of valve body 4, the other end is passed by spool 6;
Spool 6 one sides that pass valve body 4 link to each other with external knob 3, and spool 6 opposite side centers inwardly have cavity 10, and the other end of cavity 10 leads to the lower chamber that is communicated with outlet passageway 8;
A kind of coal gas air throttle of the utility model has changed existing kitchen range valve and must rotate the drawback of closing by hand, changes push-pull switch into, simple in structure, it is safe and reliable to operate, time saving and energy saving, avoid unnecessary energy waste, fully reached the effect of energy-saving consumption-reducing.
Four, description of drawings
Fig. 1: be the utility model air throttle structural representation;
Among the figure, 1, seal ring, 2, the ring washer cover, 3, handle, 4, valve body, 5, flange plate, 6, spool, 7, gas-entered passageway, 8, outlet passageway, 9, cavity, 10 cavities.
Five, embodiment
Following with reference to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model is further specified.
A kind of coal gas air throttle of present embodiment is with reference to figure 1, comprises by flange plate 5 being installed on valve body 4 on the kitchen range, and the top closure of valve body 4, the other end is passed by spool 6; Valve body 4 middle parts are provided with the cavity 9 of an installation spool 6, the periphery toward lower edge spool 6 is provided with seal ring 1 at interval from closed end in the cavity 9, seal ring 1 is divided into upper and lower cavity with cavity 9, in order to reach good sealing effect, combine closely between seal ring 1 and the spool 6, be provided with ring washer cover 2 between the seal ring 1 and carry out fixing seal, the both sides of valve body 4 are respectively equipped with gas-entered passageway 7 and the outlet passageway 8 in the gas piping of being connected in that communicates with upper and lower cavity; Spool 6 one sides that pass valve body 4 link to each other with external knob 3, and spool 6 opposite side centers inwardly have cavity 10, and the other end of cavity 10 leads to the lower chamber that is communicated with outlet passageway 8; Spool 6 can be reciprocating along cavity 9, when external knob 3 outwards spurs, spool 6 is taken out outside cavity 9, when spool 6 apical positions are lower than the upper cavity top, the gas that enters upper cavity is discharged along cavity 10, lower chamber, outlet passageway 8, this is a working state, in the time of need quitting work, external knob 3 is inwardly promoted, spool 6 arrives the closed top end of cavity 9, cavity 10 is blocked, and gas-entered passageway 7 no longer is communicated with outlet passageway 8, and this is for closing valve.
Operating process is as follows:
When needs work, external knob 3 outside one is drawn, gas enters in the upper cavity of valve body 4 by gas-entered passageway 7, discharge via cavity 10, lower chamber, outlet passageway 8 again, this moment, the kitchen range combustion gas can be used, when needs are closed, must not use hand, only handle is inwardly touched gently and got final product throttle down by certain position of health.
A kind of coal gas air throttle of present embodiment has changed the drawback that existing kitchen range valve must be closed with hand, and simple in structure, it is safe and reliable to operate, time saving and energy saving, has avoided unnecessary energy waste, fully reaches the effect of energy-saving consumption-reducing.
