Abstract
The utility model relates to an automatic gas stop valve which is suitable to be arranged at the front of the gas implement. The utility model comprises a valve casing, a valve core, and a knob. The utility model is characterized in that the lower part in the valve core is provided with a gas stop ball, and the outlet of the side wall of the valve core is a conical outlet; a transition connecting body and the knob are connected in turn upwards at the top part of the valve core, the valve core and the transition connecting body are connected by a sliding key and a spring, and the transition connecting body and the knob are connected by a fastening screw; the inner wall on the upper part of the valve casing is provided with an axial positioning baffle ring. The utility model has the characteristics of reasonable structure, low cost, convenient installation and operation, high safety, and reliable performance; the utility model is suitable for various gas users.
Description
The utility model belongs to the gas valve technical field, specifically a kind of automatic air-stopping valve of combustion gas that uses before Gas appliance.
Along with the modernization day by day of urban development, people use combustion gas also more and more universal in daily life, are very easy to numerous residents.But the accident that causes because of gas leakage also happens occasionally.Use the valve before Gas appliance to be common stopcock or ball valve at present, (cause gas consumption to heighten as combustion gas tool fault, form partial combustion, produce harmful gas when they increase unusually in gas flow; Combustion gas tool sebific duct comes off or the like), can not close gas circuit automatically; In addition, valve does not have safty device, is not intended to touch valve and can causes combustion gas to leak yet, and brings potential danger to daily life.
The purpose of this utility model provides a kind of gas flow when uprushing can safe automatic cut-off the automatic air-stopping valve of combustion gas.
The purpose of this utility model is achieved in that it includes valve casing, spool, knob, fastening screw trip bolt, it is characterized in that bottom in spool is provided with one and ends balloon, and the outlet of spool sidewall is a conical outlet; Top at spool upwards is connected with transition connecting body and knob in turn, spool and transition connecting body adopt feather key, and spring is connected, the transition connecting body is connected with knob employing fastening screw trip bolt; The inwall on valve casing top is provided with the axially locating back-up ring.During normal the use, combustion gas from spool with only pass through between the balloon; When tolerance increases unusually, gas will end balloon and dash, and gas pressure will end balloon and get lodged on the spool conical outlet, and combustion gas can not be outflowed; Pending fault rotates counterclockwise knob after handling, and valve is returned to normal operating condition,
The utility model is included in that symmetry is set with the rotating position catch on the axially locating back-up ring, and this rotating position catch is embedded in the groove at pairing transition connecting body top.
The utility model also comprises in order to open when hindering the air-stopping valve that automatic cut-off closes for some reason, and has a groove on a side horizontal position at spool sidewall conical outlet place, is set with a reseting plate on the pairing valve casing of groove.
The utility model is installed between gas pipe line end and the gas appliance, and it can be in the valve ventilation be used, and when gas flow in the valve increased to a certain amount of (coming off or the like as combustion gas tool fault, sebific duct) unusually, valve was closed gas circuit automatically.Valve is in " pass " when position, not to pressing down knob and turning knob simultaneously, then can not Open valve, thus improved the Safety performance of gas appliance early gate widely.Characteristics such as that the utility model also has is rational in infrastructure, with low cost, easy to install, reliable performance are applicable to various combustion gas users.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model sectional structure chart
Fig. 2 is that the A-A of Fig. 1 is to sectional view
Fig. 3 is the plan view of Fig. 1
Shown in Fig. 1-3: 8 as shown in the figure is that valve casing, 7 is that spool, 2 is knob, and the bottom in spool 7 is provided with one and ends balloon 9, and the outlet of spool sidewall is a conical outlet 11; Upwards be connected with transition connecting body 3 and knob 2 in turn at the top of spool 7, spool and transition connecting body 3 adopt feather keys 12, and spring 6 is connected, the transition connecting body is connected with knob employing fastening screw trip bolt 1; The inwall on valve casing 8 tops is provided with axially locating back-up ring 4, and symmetry is set with rotating position catch 5 on the axially locating back-up ring, and this rotating position catch 5 is embedded in the groove at pairing transition connecting body top.When in order to open when hindering the air-stopping valve that automatic cut-off closes for some reason, then on a side horizontal position at spool sidewall conical outlet place, have a groove, on the pairing valve casing of groove, be set with a reseting plate 13, that is to say that reseting plate fixes in valve casing, and embed in the spool groove.Among the figure 10 is for being arranged on the spacing spacing catch that ends balloon 9 of spool 7 bottoms in addition.After said structure was installed, spring was by pretension, and spool and valve casing seal.During normal the use, combustion gas is passed through (state as shown in the figure) from spool with ending between the balloon; When tolerance increases unusually (increase unusually as the combustion gas tool gas consumption that breaks down, the fracture of combustion gas sebific duct, the combustion gas sebific duct comes off etc.), gas will end balloon and dash, and gas pressure will end balloon and get lodged on the spool conical outlet 11, and combustion gas can not be outflowed.After fault treatment, rotate counterclockwise knob to " pass " position, valve core rotation and drive reseting plate and will end balloon and push back and fall in the spool bottom, this moment, valve returned to normal opening state, turning knob again, spool does not have the sidewall of groove and seals the valve casing gas outlet, and this valve is a closed condition.In addition, under the effect of spring force, rotating position catch 5 embeds in the groove at pairing transition connecting body 3 tops, when needing to open this valve, have only and press knob (making the rotating position catch break away from the groove at transition connecting body top) and while rotary knob ability Open valve downwards, thereby prevented to cause valve to open by mistake because of being not intended to scratching.
Claims (3)
