Description
Technical field
The utility model belongs to environmental sanitation vehicles field, particularly relates to a kind of stainless steel water tank applied to environmental sanitation product
Air-tightness detection device.
Background technology
It needs to carry out leak detection after the welding of environmental sanitation product stainless steel water tank, to ensure the leakproofness of water tank.Leak detection
Method mainly has air pressure detection and water filling detection, since environmental sanitation product large-size stainless steel cisten mechanism complexity bearing capacity is poor,
In view of safety problem, generally use water filling leak detection mode, this mode goes out there is of high cost, waste water resource, easily
The problems such as existing missing inspection.Air pressure detects, and has the advantages of at low cost, omission factor is low, particularly suitable for environmental sanitation product large-size stainless steel
How the leak detection of water tank improves the security of air pressure detection mode, is one urgently to be resolved hurrily so as to expand application range
Problem.
The content of the invention：
The purpose of this utility model is precisely in order to improving the security of environmental sanitation product water tank air pressure detection mode and providing
A kind of detection device, the device can ensure that water tank operating pressure without departing from safety value, so as to ensure safety, while solves note
There is the problem of missing inspection there is of high cost, waste water resource, easily in water leak detection mode.
The purpose of this utility model can be realized by following technique measures：
The stainless steel water tank air-tightness detection device of the utility model includes pressure limiting tank, and the air inlet of the pressure limiting tank passes through
Valve I is connected with source of the gas, and the gas outlet of the pressure limiting tank passes through valve II, pressure reducing valve, throttle valve and corresponding connecting tube
Road is connected with detected water tank；Overflow valve is provided on the pressure limiting tank；Safety is provided on the detected water tank
Valve；The valve I and valve II are set using the linked manner that a valve opening, another valve are closed or simultaneously closed off.
Valve I described in the utility model and valve II are installed by the way of being arranged in parallel up and down, and the valve I and
The handle front end of valve II is equipped with interior concave arc, the opposite installation of handle front end indent circular arc portion of valve I and valve II, and protects
The handle of card valve I and valve II is in the same plane（Two valves simultaneously close off at this time）；Before the interior concave arc and handle
The periphery in portion is engaged, and in any one rotatable handle, which is equipped with interior concave arc outer point and the other hand
The contact point of the periphery of handle forepart and the line of the centre of gyration of two handles are in 90 °, to realize that handle is in self-locking state, keep away
Exempt to open by mistake and open another handle.
The operation principle of the utility model is as follows：
During pressure testing, valve I is opened（Valve II is closed at this time）, limit is entered from the compressed air of source of the gas output
It presses in tank, closes valve I after reaching setting pressure, open valve II（Valve I is closed at this time, the company of cut-out source of the gas and pressure limiting tank
It is logical）, the compressed air in pressure limiting tank enters water tank through pressure reducing valve, throttle valve.
The beneficial effects of the utility model are as follows：
Since the utility model has used pressure limiting tank, the pressure of pressure limiting tank is set according to the volume of water tank and the pressure of needs
Fixed, the pressure of pressure limiting tank is higher than tank pressure, and the part exceeded is only used for supplying the part of water tank pressurization, so as to ensure water tank
Operating pressure without departing from safety value；The intake valve of pressure limiting tank and air outlet valve ensure that source of the gas gas using linkage simultaneously
Body cannot be passed directly into water tank, further promote safety in utilization.Usual water tank operating pressure is in 0.02-0.03MPa or so（Table
Pressure）.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is state when two handles simultaneously close off.
Fig. 3 is that valve I is opened, state when valve II is closed.
Fig. 4 is that valve II is opened, state when valve I is closed.
Specific embodiment
The utility model is below with reference to embodiment（Attached drawing）It is further described：
As shown in Figure 1, the stainless steel water tank air-tightness detection device of the utility model includes pressure limiting tank 3, the pressure limiting tank 3
Air inlet be connected by valve I 2 with source of the gas 1, the gas outlet of the pressure limiting tank 3 passes through valve II 5, pressure reducing valve 6, throttle valve
7 and corresponding connecting line be connected with the water tank 8 being detected；Overflow valve 4 is provided on the pressure limiting tank 3；It is described tested
Safety valve 9 is provided on the water tank 8 of survey；The valve I 2 and valve II 5 closed using a valve opening, another valve or
The linked manner simultaneously closed off is set；The valve I 2 and valve II 5 are installed by the way of being arranged in parallel up and down, and the valve
The handle front end of door I 2 and valve II 5 is equipped with interior concave arc, and valve I 2 is opposite with the handle front end indent circular arc portion of valve II 5
Installation, and ensure the handle 10 of valve I 2 and valve II 5 in the same plane（Two valves simultaneously close off at this time）；The indent
Circular arc is engaged with the periphery of handle forepart, and in any one rotatable handle, which is equipped on the outside of interior concave arc
