Abstract
The utility model discloses a pressure test device for a methane tank, belonging to the technical field of methane tank quality detection. The pressure test device comprises an air pump, a hose, a pressure gauge, a joint, a one-way valve and a valve, wherein one end of the hose is connected to an air outlet of the air pump and the other end is connected to the valve, the other end of the valve is connected to an inlet end of the one-way valve through the hose, an outlet end of the one-way valve is connected with the joint, the pressure gauge is arranged between the joint and the one-way valve, and an air outlet of the methane tank is connected to the joint. A material feeding port, a material discharge port and a return pipe of the methane tank are sealed, the joint is connected to the air outlet of the methane tank, the methane tank is inflated by the air pump, and air inflation by the air pump is stopped when the pressure reaches a certain value. It can be known quickly and accurately whether the methane tank leaks or not by watching the change of the numerical value on the pressure gauge.
Description
Technical field
The utility model relates to a kind of pressure testing equipment for methane tank, especially uses the air-pump inflating pressure testing, belongs to the methane-generating pit technical field of quality detection.
Background technology
Biogas is reproducible clean energy resource, both traditional biomass energy such as alternative stalk, fuel wood, and the also commercial energy such as alternative coal, and also energy efficiency is apparently higher than stalk, fuel wood, coal etc.New-built Methane Tank all must be through could using after the pressure testing, and current methane-generating pit pressure testing is divided into that hydrostatic(al) process is gentle, two kinds of water mixing pressure testing methods.There is technician's longevity of service in the hydrostatic(al) process pressure testing, need to carries out the problems such as secondary water filling; Gas, water mixing pressure testing method also need to pour into certain water toward methane-generating pit, need to watch the variation of methane-generating pit water level in the pressure testing process, and this method of water level of watching is sensitive not for little gas leakage point.
Summary of the invention
The purpose of this utility model provides a kind of pressure testing equipment for methane tank.
Problem to be solved in the utility model is the not deficiency of sensitivity and trivial operations of existing methane-generating pit pressure-measuring method.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
The utility model pressure testing equipment for methane tank, comprise air pump, flexible pipe, tensimeter, joint, retaining valve and valve, flexible pipe one terminates at the gas outlet of air pump, the other end is connected to the valve place, the other end of valve is connected on the entrance point of retaining valve by flexible pipe, the endpiece of retaining valve is by the flexible pipe joint of ining succession, and tensimeter is contained between joint and the retaining valve, and the joint is received in the methane-generating pit gas outlet.
The utility model has the advantages that: sludge gas pond feed, discharging opening and the backflow mouth of pipe are all sealed, joint is connected on the methane-generating pit gas outlet, utilize air pump that methane-generating pit is inflated, after being charged to certain pressure, stop air-pump inflating; By watching manometric numerical value change, can know quickly and accurately whether methane-generating pit has leakage, has simple, convenient characteristics.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model pressure testing equipment for methane tank;
Among the figure: 1, air pump 2, flexible pipe 3, tensimeter 4, joint 5, retaining valve 6, valve.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, the utility model pressure testing equipment for methane tank, comprise air pump 1, flexible pipe 2, tensimeter 3, joint 4, retaining valve 5 and valve 6, flexible pipe 2 one terminates at the gas outlet of air pump 1, the other end is connected to valve 6 places, the other end of valve 6 is connected on the entrance point of retaining valve 5 by flexible pipe 2, the endpiece of retaining valve 5 is by flexible pipe 2 joint 4 of ining succession, gas can only flow to endpiece from the entrance point of retaining valve 5, and can not flow to entrance point from endpiece, gas can not be back to air pump 1 from methane-generating pit when air pump 1 quits work, when charge pressure reaches eight kPas, stop air pump 1, valve-off 6; Valve 6 plays a protective role, and the size of control valve 6 is controlled charge pressure in air pump 1 gas replenishment process, and excessive charge pressure can be damaged methane-generating pit; Tensimeter 3 is contained between joint 4 and the retaining valve 5, and joint 4 places are received in the methane-generating pit gas outlet.
The utility model using method is at first sealed sludge gas pond feed, discharging opening and the backflow mouth of pipe, and the loess that cohesive is good dries, and moulds synthetic stick with water spray behind the crushing screening, makes it not split tack-free being advisable.The mud bar is made the upper ring along wide three cm thicks of face with Chi Kou, again five centimetres of yellow muds that the left and right sides is wide are smeared at the pond lid end along the limit, Chi Gai is aimed at Chi Kou equate with water seal circle spacing around making, steadily put down, tread with bipod.Fill between Chi Gai and water seal circle with the yellow mud bar again, simultaneously with the wooden stick tamping of exerting oneself, until fill up till the tamping.Joint 4 is received the methane-generating pit gas outlet, open valve 6, booster air pump 1, control valve 6 is controlled charge pressure.Smear yellow mud ring sealing part with finger-dipping water, if bubble is arranged, firmly binder is until the point that do not leak gas.When tensimeter 3 pressure reach six kPas, valve 6 is turned down, air pump 1 stops inflation after continuing slowly to be inflated to eight kPas, and valve 6 is closed.Seeing behind the twenty four hours whether tensimeter 3 numerical value change gets final product.
