Description
Technical field
The invention belongs to environmental sanitation vehicles field, and it is airtight to particularly relate to a kind of stainless steel water tank applied to environmental sanitation product
Property detection means.
Background technology
Need to carry out leak detection after the welding of environmental sanitation product stainless steel water tank, to ensure the sealing of water tank.Leak detection
Method mainly has air pressure detection and water filling detection, because 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 is there is cost height, waste water resource, easily go out
The problems such as existing missing inspection.Air pressure detects, and has the advantages of cost is low, and loss is low, particularly suitable for environmental sanitation product large-size stainless steel
The leak detection of water tank, the security of air pressure detection mode how is improved, be one urgently to be resolved hurrily so as to expand application
Problem.
The content of the invention：
The purpose of the present invention is precisely in order to a kind of detection for improving the security of environmental sanitation product water tank air pressure detection mode and providing
Device, the device can ensure that water tank operating pressure without departing from safety value, so as to ensure safety, while solves water filling leakage inspection
Survey mode is there is cost height, waste water resource, easily there is the problem of missing inspection.
The purpose of the present invention can be realized by following technique measures：
The stainless steel water tank air-tightness detection device of the present invention includes pressure limiting tank, the air inlet of the pressure limiting tank by valve I and
Source of the gas is connected, and the gas outlet of the pressure limiting tank is by valve II, pressure-reducing valve, and choke valve and corresponding connecting line are with being detected
The water tank connection of survey；Overflow valve is provided with the pressure limiting tank；Safety valve is provided with the detected water tank；The valve
The linked manner that door I and valve II are closed or simultaneously closed off using a valve opening, another valve is set.
Heretofore described valve I and valve II are installed by the way of be arrangeding in parallel up and down, and the valve I and valve
II handle front end is provided with interior concave arc, and the handle front end indent circular arc portion of valve I and valve II is mounted opposite, and ensures valve
The handle of door I and valve II is in the same plane（Now two valves simultaneously close off）；The interior concave arc and handle front portion
Periphery is engaged, in any one rotatable handle, before the handle front end is provided with interior concave arc outer point and another handle
The line of the contact point of the periphery in portion and the centre of gyration of two handles is in 90 °, to realize that handle is in self-locking state, avoids missing
Open another handle.
The operation principle of the present invention is as follows：
During pressure testing, valve I is opened（Now valve II is closed）, pressure limiting tank is entered from the compressed air of source of the gas output
In, valve I is closed after reaching setting pressure, opens valve II（Now valve I is closed, the connection of cut-out source of the gas and pressure limiting tank）,
Compressed air in pressure limiting tank enters water tank through pressure-reducing valve, choke valve.
Beneficial effects of the present invention are as follows：
To be set because present invention uses the pressure of pressure limiting tank, pressure limiting tank according to the volume of water tank and the pressure of needs, pressure limiting
The pressure of tank is higher than tank pressure, and its part exceeded is only used for supplying the part of water tank pressurization, so as to ensure the work of water tank
Pressure is without departing from safety value；The intake valve of pressure limiting tank and air outlet valve use linkage simultaneously, ensure that source gas can not
Water tank is passed directly into, further lifts safety in utilization.Usual water tank operating pressure is in 0.02-0.03MPa or so（Meter pressure）.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
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.
Embodiment
The present invention is below with reference to embodiment（Accompanying drawing）It is further described：
As shown in figure 1, the stainless steel water tank air-tightness detection device of the present invention includes pressure limiting tank 3, the air inlet of the pressure limiting tank 3
It is connected by valve I 2 with source of the gas 1, the gas outlet of the pressure limiting tank 3 is by valve II 5, pressure-reducing valve 6, choke valve 7 and phase
The connecting line answered is connected with detected water tank 8；Overflow valve 4 is provided with the pressure limiting tank 3；The detected water tank
Safety valve 9 is provided with 8；The valve I 2 and valve II 5 are closed or simultaneously closed off using a valve opening, another valve
Linked manner set；The valve I 2 and valve II 5 are installed by the way of being be arranged in parallel above and below, and the valve I 2 and valve
The handle front end of door II 5 is provided with interior concave arc, and the handle front end indent circular arc portion of valve I 2 and valve II 5 is mounted opposite, and
The handle 10 of guarantee valve I 2 and valve II 5 is in the same plane（Now two valves simultaneously close off）；The interior concave arc with
The anterior periphery of handle is engaged, in any one rotatable handle, the handle front end be provided with interior concave arc outer point with
The line of the contact point and the centre of gyration of two handles of the anterior periphery of another handle is in 90 °, to realize that handle is in self-locking
