Abstract
The utility model discloses a piezometric device of a fuel gas micro pressure meter, which comprises a micro pressure meter and a meter valve connected with the micro pressure meter. The utility model has the advantages that the piezometric device of the fuel gas micro pressure meter is safe in use, the meter valve is normal in a close state; and only when the pressure in a gas pipe is needed to be tested, a button is pressed for communicating an inlet passage with an outlet passage, the micro pressure meter is used for testing the pressure in the gas pipe, and no damage to the micro pressure meter is caused, thereby reducing the use cost.
Description
Technical field
The utility model relates to a kind of gas pressure detection unit, relates in particular to a kind of combustion gas micromanometer pressure tester.
Background technology
The combustion gas micromanometer is a kind of a kind of equipment that is used for measuring slight pressure in the Gas Pipe, during use, micromanometer is contained in the exit of city gas voltage adjusting device pressure regulator, is used to measure the pressure in pressure regulator exit, and its use has replaced U type water column pressure instrument in the past.When micromanometer is installed on the pipeline, be connected with the table valve between pipeline and the micromanometer.The structure of existing table valve comprises: valve body, valve shaft and valve gap, valve pocket is set in valve body, one end of valve shaft is arranged in the valve pocket, the other end of valve shaft is provided with handle, is respectively arranged with in valve body and Gas Pipe the cooperatively interact inlet channel that is connected and the outlet passageway that cooperatively interacts and be connected with the micromanometer inlet channel.Realize that by the handle rotary valve shaft connected sum between inlet channel and the outlet passageway is obstructed.When needing to show the pressure regulator outlet pressure, hand-turning table valve handle is opened the source of the gas passage, and this moment, micromanometer showed pressure regulator top hole pressure value.When test finishes when not needing indicating value, at first the pipeline pressure emptying to be closed the table valve by handle again.Adopt above-mentioned table valve to measure the pressure in pressure regulator exit, tend to cause following drawback: operating personnel did not remove observation table valve state (Push And Release) when 1, product used, if the table valve is in open mode, pressure will wash out micromanometer much larger than the micromanometer range during because of pipeline pressure test during pressure testing; 2, equipment breaks down before micromanometer, and the pressure behind the equipment raises gradually, as not finding immediately that when pressure exceeded the micromanometer range, micromanometer will be damaged.
The utility model content
Technical problem to be solved in the utility model is: a kind of combustion gas micromanometer pressure tester safe in utilization is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: combustion gas micromanometer pressure tester, comprise: micromanometer and the table valve that is connected with micromanometer, the structure of table valve comprises: valve body, valve shaft and valve gap, in valve body, be respectively arranged with the inlet channel that cooperatively interacts and be connected with Gas Pipe, valve pocket and the outlet passageway that cooperatively interacts and be connected with the micromanometer inlet channel, be connected by valve pocket between inlet channel and the outlet passageway, one end of described valve shaft is arranged in the valve pocket, an end of valve shaft is provided with circular cone in the valve pocket, the other end of valve shaft is provided with button, on valve shaft and circular cone, be arranged with spring, be respectively arranged with O-ring seal at the two ends of spring, under the normal condition, circular cone can be blocked valve pocket, make between inlet channel and the outlet passageway and can not be communicated with, when needing to detect the Gas Pipe internal pressure, press the button, valve shaft and circular cone move, spring is compressed, and at this moment, is communicated with by valve pocket between inlet channel and the outlet passageway.
In order to solve the problems of the technologies described above better, the further technical scheme that the utility model adopts is: also be provided with the interface channel that cooperatively interacts with outlet passageway between described inlet channel valve pocket.
The utility model has the advantages that: above-mentioned combustion gas micromanometer pressure tester, safe in utilization, the table valve normally is in closed condition, only when needs test Gas Pipe internal pressure, just can press the button, inlet channel is communicated with outlet passageway, micromanometer detects the pressure in the Gas Pipe, micromanometer is caused with bad, reduce use cost.
