Abstract
The utility model relates to an improved fuel gas safety valve. A gear is mounted on a hand wheel, a spring is mounted on one side, close to the valve, of the gear, and a mechanical timer is connected with the gear through a transmission gear; the outer diameter of a pressure lever is smaller than that of the transmission gear, and the pressure lever is arranged on the transmission gear; a temperature control plate is arranged above the pressure lever, the periphery of the temperature control plate is attached to the pressure lever, and the center of the temperature control plate is attached to the mechanical timer; an annular gate is further arranged inside a pipeline, and is connected with a spring connected with a butterfly valve, a step is arranged on a pipeline between the annular gate and the butterfly valve, and another step is also arranged on the other side of the annular gate. The mechanical timer is used in a timing manner for fuel gas, and the temperature control plate is used for dealing with fire disasters; when the mechanical timer and the temperature control plate break down unexpectedly, the gate is driven to move by utilizing the flowing of airflow, so that the butterfly valve is pushed to be closed through the stretching or retraction of the spring; moreover, when the air pressure is too high or too low, the gate can also achieve the effects of sealing pipe belts and preventing gas leakage.
Description
Technical field
The utility model relates to valve technology field, particularly a kind of improved fuel gas safety valve door.
Background technique
The main fuel using in liquid gas, rock gas people daily life, but the hidden danger of its existence but allows people worry all the time.The situations such as gas leakage, fire are used and occur, and people's the security of the lives and property in this serious harm.For combustion gas stop the supple of gas or steam, the too low or many height of air pressure, flexible pipe come off flow excessive, there are these situations such as fire, have corresponding prior art to propose relevant countermeasure.But some function is relatively single, some is too complicated again, and if these functions all there is fortuitous event, how this solves, this has been to be again worth the problem of our thinking.
Model utility content
The purpose of this utility model is to provide a kind of improved fuel gas safety valve door.
Realize the technical solution of the utility model as follows:
A kind of improved fuel gas safety valve door, comprises valve, spring, gear, handwheel, driving gear, mechanical timer, and gear is arranged on handwheel, and spring fitting is near a side of valve on gear, and mechanical timer is connected by driving gear with gear; Also comprise temperature control sheet, depression bar, described depression bar external diameter is less than driving gear, and depression bar is arranged on driving gear, and described temperature control sheet is arranged on depression bar top, and periphery and depression bar are affixed, center and mechanical timer are affixed; Also be provided with ring gate at pipe interior, on ring gate, be connected with a spring being connected with butterfly valve, on the pipeline between ring gate and butterfly valve, be provided with step, be also provided with step at the opposite side of ring gate.
The beneficial effects of the utility model are: mechanical timer uses using gas-time to carry out timing, there is the situation of fire in the reply of temperature control sheet, when above-mentioned both occur fortuitous event occur time, no matter be that air pressure is too low or too high, utilize air current flow to drive gate motion, thereby stretching or contraction promotion butterfly valve by spring are closed, in addition when air pressure is excessive or too low, gate also can play sealing pipe racks, prevent the effect of gas leakage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In accompanying drawing, 1 is valve, and 2 is step, and 3 is ring gate, and 4 is spring A, and 5 is gear, and 6 is handwheel, and 7 is spring B, and 8 is butterfly valve, and 9 is temperature control sheet, and 10 is depression bar, and 11 is timer knob, and 12 is driving gear, and 13 is mechanical timer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described;
Shown in Figure 1, a kind of improved fuel gas safety valve door, comprise valve 1, spring A4, gear 5, handwheel 6, driving gear 12, mechanical timer 13, gear 5 is arranged on handwheel 6, spring A4 is arranged on the side near valve 1 on gear 5, and mechanical timer 13 is connected by driving gear 12 with gear 5; Also comprise temperature control sheet 9, depression bar 10, described depression bar 10 external diameters are less than driving gear 12, and depression bar 10 is arranged on driving gear 12, and described temperature control sheet 9 is arranged on depression bar 10 tops, and periphery and depression bar 10 are affixed, center and mechanical timer 13 are affixed; Also be provided with ring gate 3 at pipe interior, on ring gate 3, be connected with a spring B 7 being connected with butterfly valve 8, on the pipeline between ring gate 3 and butterfly valve 8, be provided with step 2, be also provided with step 2 at the opposite side of ring gate 3.
Mechanical timer 13 uses using gas-time to carry out timing, timer knob 11 buttons that are rotatably mounted on mechanical timer 13 are determined the gas time of using, rotation hand wheel 6, butterfly valve 8 is opened, gear 5 rotates, and the spring A4 being arranged on gear 5 is tightened up, and gear 5 rotates band nutating gear 12 and rotates, energy is passed to mechanical timer 13, and driving gear 12 blocks in the office in mechanical timer 13.Arrive after service time, the energy being stored in mechanical timer 13 discharges by driving gear 12, and gear 5 is closed butterfly valve 8 under the acting in conjunction of spring A4 and driving gear 12.
There is the situation of fire in 9 replies of temperature control sheet, occurs the condition of a fire, and temperature control sheet 9 is out of shape, and central protuberance toward pressing down, departs from driving gear 12 and gear depression bar 10, and gear 5 is rotary closing butterfly valve 8 under the effect of spring A4.
When above-mentioned both occur fortuitous event occur time, no matter be that air pressure is too low or too high, utilize air current flow to drive gate 3 to move, thereby close by stretching or the contraction promotion butterfly valve 8 of spring B 7, in addition when air pressure is excessive or too low, gate 3 also can play sealing pipe racks, prevent the effect of gas leakage.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
