Detailed Description
Fluid line systems are typically constructed from various tubing, various fluid handling components, and various instrumentation, and the like. For fluid delivery, the fluid handling components therein typically need to be sealed to prevent fluid leakage. Also, in other scenarios, where the fluid is delivered, such as under high pressure conditions, the fluid handling component may also need to have some pressure bearing properties.
In addition, the operating conditions of some fluid handling components, such as operating voltage, operating current, etc., need to be monitored; or to know the pressures that these fluid handling components can withstand under different operating voltage, operating current conditions, and the flow rates that can be generated.
Further, it is desirable to detect properties such as density, composition, conductivity, pH, etc. of the transport fluid in the fluid piping system.
In other words, it is desirable in the industry to know and understand the various devices in a fluid line system or their operating conditions. Therefore, it is necessary to detect it.
In which tightness, pressure, flow, conductivity, operating current, operating voltage of fluid handling components such as pumps, valves, RO membranes are important indicators of the performance of these components. In order to detect some of the above items, it is necessary to connect the fluid handling components to different piping systems, which can obviously cause inconvenience.
In view of such a situation, in an example of the present application, the inventors have proposed a test device that is capable of detecting some selected transport conditions of a fluid in a piping system, and that is simple to operate and convenient to use.
The testing device can be used to test selected parameters of the fluid handling component.
The fluid handling component may be various fluid handling components such as pumps, solenoid valves, RO membranes or various other components.
Selected parameters include, for example, operating voltage, operating current, power, etc.
In addition, the test device may be used to detect the flow, pressure, conductivity, temperature rise, etc. of a fluid being conveyed (which may be a gas, liquid, or other object in a viscous or molten state). That is, according to different functional configurations, the testing device can test not only the working conditions and working conditions of the fluid processing component, but also some properties of the fluid to be conveyed.
This is mainly dependent on the specific type and kind of test element configured in the test device, the composition of the transported object (fluid), and the specific type of object to be tested (fluid handling component). And this can be determined by making the test device at the time of production. In other words, depending on the function of the test device, different test elements can be configured during production according to the respective fluid-handling components that can be tested, so that the respective selected parameters can be obtained therefrom.
Generally, the test apparatus in the examples includes a base, a test seat, and a piping system. Wherein, test seat and pipe-line system set up respectively on the base. The test socket is used to mount a test object (otherwise known as a test object, a fluid treatment component, or a water treatment component). The pipeline system is used for conveying fluid (various liquids or gases, such as water, natural gas, and the like), and is connected with the test seat, so that the tested object can be conveniently installed on the test seat and then connected to the pipeline system; and further, fluid delivery may be performed accordingly, and detection of the relevant item is performed by a test element arranged in the piping system.
The individual components of the test apparatus in the examples will be described in detail below with reference to the accompanying drawings (fig. 1 to 6).
Base seat
The base provides space, location for the other various components in the test device to secure and mount, and the various components may be connected, for example, by clamping, bonding, welding, bolting, etc., in a variety of suitable ways.
The shape thereof may be various, and the present application is not particularly limited as to the specific configuration of the base. In an example, the base may be a frame structure formed by assembling and connecting angle steel, steel plate (plastic or resin material or wood plate) through welding or bolting or clamping, hinging and the like. Or the base can also be a structure which is combined by plane plates and is erected; for example, it comprises a planar plate and four posts connected to the planar plate. Alternatively, the base is a box structure having a box and a cover rotatably connected or nested with each other by, for example, a hinge.
In the structure shown in the drawings of the present application, as shown in fig. 1, the base includes a first plate 48 and a second plate (not shown) and the two plates are connected in a longitudinal and transverse manner, for example, by welding. Therefore, the two plates are made of weldable materials, such as steel plates and iron plates. Thus, the base is generally "L" shaped in the illustrated construction. And, based on the general use and manner of the testing device, the first plate 48 is laid flat on various planes, while the second plate is in a standing state and is, for example, vertical.
Wherein the base has a first mounting portion and is located on the first plate 48; the first mounting portion is at least partially located in the first plate 48, in other words it may also be partially located in the second plate. Further, the base is also provided with a second mounting part, and the second mounting part is positioned on the second plate body.
Test seat
The structure of the test socket is shown in fig. 1 and 3.
The test seat is the main component for mounting the water treatment component. And based on the fluid delivery requirements, the test seat also has a first connector and a second connector (each having a channel for fluid delivery), and therefore can be accessed into the piping system accordingly. In order to reserve or facilitate the installation of the water treatment component, the joint can be provided with cushion blocks (the first cushion block 7 and the second cushion block 9 in an exemplary way) so as to lift the joint so as to be connected with the water inlet and outlet of the water treatment component at the same height, and the occurrence of the condition that the connection part is not beneficial to connection, such as bending, is prevented.
The first and second connectors may be various quick-connect connectors or ferrule-type connectors or swaged connectors or their manufacture. Further, the first joint can be selectively provided with a first valve; accordingly, the second connector may optionally be provided with a second valve. The two valves can block fluid communication between the water treatment component and the pipeline system, thereby facilitating replacement of the water treatment component; and also to facilitate testing of other components or fluid delivery when necessary.
In an example, the test socket is mounted on the first mounting portion of the base, see fig. 1 of the drawings.
In addition, the test seat may also have other components based on the differences in the water treatment components.
For example, when the water treatment component is a pump, it requires live working. The test socket is therefore provided with electrically conductive contacts or terminals, which may be plug-in or contact-type conductive elements, and is also connected to the wires provided at the base; wherein the wires may be disposed on the back or inside of one or both of the first plate 48 and the second plate-hiding the traces more aesthetically pleasing-to avoid accidental damage. When the testing device is used for testing, the wire is connected with a power supply, which can be commercial power or a proper power supply for adjusting parameters such as voltage, current and the like through a power adapter.
When a water treatment element, such as an RO membrane, does not require conductive operation, the test seat may optionally be configured without conductive contacts or tabs as described above. However, based on flexibility of use and functional richness considerations, the test sockets may be optionally equipped with the contacts or joints described above for use as desired.
Alternatively, in other examples, multiple test seats may be provided in the test device-two, or three, or more, i.e., at least two-and different test seats may be selected for corresponding structural and functional designs for different water treatment components.
Accordingly, as an example, for the case with multiple test seats:
the first joint comprises a first sub-joint 8 and a first sub-valve 6; the first joint further comprises a first sub-joint 10 and a first sub-valve 11.
The second connection comprises a second sub-connection 18 and a second sub-valve 19; the second joint further comprises a second sub-joint 17 and a second sub-valve 16.
Wherein the first sub-joint 8 and the first sub-joint 10 may be fixed parts and the second sub-joint 18 and the second sub-joint 17 may be movable parts, and may also be controlled by a locking mechanism mentioned later, to strengthen the installed water treatment parts.
In addition, reinforcing structures may be provided in the test seats based on the need to secure the water treatment components. For example, a clip is provided in the test seat and is threadably connected to the first plate 48 in the base by bolts. After the water treatment component is installed in place, the water treatment component can be pressed at the proper position by the clamp and then fixed by bolts. Alternatively, the test seat may be provided with a mounting slot into which the water treatment component may be snapped for securement.
In the illustrated structure of the application, the first connector of the test seat is fixedly arranged on the base, and the second connector is movably arranged on the base. As a specific and alternative example, the first joint is a block of material, such as a stainless steel block, and has a fluid passage for delivering a fluid and connecting to a water inlet of the water treatment component. And the second joint is a part connected with the water outlet of the water treatment part. It may also be bulk material and it also has fluid passages. At the same time, the second joint also has a movable member which can be squeezed so that the water treatment member is pressed against and tightly and firmly connected to the fluid passage. And the first and second joints may be provided with rubber or other resilient gaskets to provide a sealing closure for the seal.
The testing device may further comprise a locking mechanism provided to the first mounting portion of the base as a component for cooperation with the movable member of the second connector, the locking and mechanism being configured to operate the second connector to selectively mount or dismount the fluid handling component. Alternatively, the second joint may be configured in a tubular body having a fluid passage without disposing the movable member. The tube body can be connected with an action piece of the locking mechanism, and the action piece moves to enable the tube body to be in sealing connection with a water outlet of the water treatment component.
As shown in fig. 1 and 3 of the drawings of the present application, the locking mechanism has a base 20 and a link mechanism connected to the base 20. Wherein the base 20 is fixed to the base and the linkage is coupled to the base 20. And wherein the linkage has a handle 23 and a slide bar, wherein the handle 23 is rotatable to operate the slide bar for telescopic movement. The slide bar can be connected with the movable piece in the second joint of the test seat. Thus, by operating the handle 23, the second joint movement can be controlled. For example, in the first state, the handle 23 is pulled up and the second connector is retracted with the slide bar, so that the second connector is disengaged from the water treatment member and the water treatment member can be removed or replaced. In another state, the handle 23 is pressed down, and the second connector extends along with the slide bar, so that the second connector is tightly abutted against the water treatment component, and the water outlet of the water treatment component can be firmly and tightly connected with the second connector.
The test sockets may be constructed as separate structural and functional modules for ease of manufacture and installation, maintenance considerations, and thus ease of assembly and disassembly on the base. Thus, in some examples, the test device further has a base, and the test socket is disposed on the first mounting portion of the base through the base. And the main components in the test seat may be attached and fixed to the base.
Pipeline system
The pipeline system is mainly composed of various fluid elements, such as pipelines, various instruments and meters for measuring liquid parameters of fluid, or test elements, and the like. It may be mounted to the base, either entirely to the first plate 48 of the base or partially to the first body and partially to the second body.
Wherein the test element is capable of testing selected parameters of the fluid handling component or further may be capable of testing the fluid being delivered. The instruments and meters described above illustratively constitute an instrument cluster, and the various instruments and meters in the instrument cluster are matingly connected to the test elements, such as a data communication connection, but may be further electrical connections. For example, the instrument cluster includes a conductivity meter, and the test element may be a conductivity meter matingly coupled to the conductivity meter. Wherein the conductivity meter is in direct contact with the fluid to be conveyed for measuring the conductivity value of the fluid; the conductivity meter is used to display the conductivity value of the liquid measured by the conductivity meter. Alternatively, in other examples, the test element may also include one or more of a pressure meter, a flow meter. In other words, the test element may be an electronic device that can independently determine and display parameters, or the test element is a measurement device and the data display device corresponding thereto is provided by the instrument cluster.
The tubing system as described above is connected to and also in fluid communication with the first and second connectors of the test seat, respectively. Also, with the water treatment component as a demarcation point, devices upstream of the water treatment component may be referred to as input stage devices and devices downstream of the water treatment component may be referred to as output stage devices, depending on the direction of fluid transport.
Further, to test the water treatment component under different conditions, the testing device may also be configured with an operating assembly disposed on the base (or more specifically and alternatively, on the second plate). The operating assembly is for mating with a fluid handling component and is capable of controlling the fluid handling component in a selected manner. The operating components and corresponding control schemes therein-selected-vary from one water treatment component to another.
For example, when the water treatment member is a pump, the operation member may be, for example, a power switch, an operating voltage switch, and an operating current switch, or when the water treatment member is the solenoid valve 14, the operation member may be an opening switch, a power switch, an operating voltage switch, an operating current switch, and the like. Alternatively, in other examples, the above partial lights may also be mentioned in the following description: a switch 29, a voltage regulator 26 and a current regulator. The individual switches may be in the form of buttons 36, levers or knobs, etc. Further, as a way of fitting these operating components with the corresponding apparatus-water treatment member-, the test device has a cable, and the cable connects the water treatment member and the above-mentioned various operating components, respectively-may be an electrical connection or a data communication connection or both. In these examples, the cable may be buried within the body of the base, or hidden wiring or cabling may be achieved by providing grooves in the plate body, or through an insulated plumbing arrangement.
The control means is, for example, the start or stop of the corresponding device, the rise or fall of the operating voltage or the operating current, the opening of the solenoid valve 14, or the like, corresponding to the above-described operation components. Further, to facilitate monitoring or supervision of the above-described control, the operating component may also be configured with a corresponding indicating or responding device. For example, an indicator light matingly connected to the switch 29; which is used to indicate on or off. A voltage display coupled to the voltage regulator 26 for displaying the operating voltage. And the current display is matched and connected with the current regulator to display the working current.
The main piping in the piping system in the illustrated construction of the present application will be described below.
The pipeline system comprises a first pipeline, a second pipeline and a third pipeline.

The structure of the third pipeline is shown in fig. 1, 2 and 6.
The third pipeline comprises a liquid inlet side pipeline and a liquid outlet side pipeline, and a detection station formed between the liquid inlet side pipeline and the liquid outlet side pipeline can be connected with the RO membrane. Namely, the RO membrane (not shown) is connected between the liquid inlet side valve 12 and the liquid outlet side valve 15, which will be described later.
The liquid inlet side pipeline comprises a liquid inlet pipe and a liquid inlet side valve 12, and the liquid inlet pipe is arranged in parallel with the first joint of the test seat through the liquid inlet side valve 12 and is connected with a first pressure regulating valve 45. That is, the water outlet of the first pipeline is split, one branch can enter the second pipeline, and the other branch can enter the third pipeline.

and a liquid discharge pipe connected to the third flow meter 39.
For convenience to those skilled in the art in practicing the present application, details will be made later in connection with the delivery path and manner of the fluid and with the testing protocols in the process.
Raw water (fluid to be transported) enters the first conductivity meter 4 from the inlet valve 2. The first conductivity meter 4 may transmit the detected value of the conductivity of the raw water to the conductivity meter.
Raw water flows out from the first conductivity meter 4 and is divided into two branches; one of the branches may pass through the booster pump 3 and the other branch may pass through the first regulating valve 5. And the two branches then merge into the first pressure gauge 42 and the first pressure regulating valve 45 in sequence. The booster pump 3 therein can boost raw water to a higher pressure, and the intake water pressure can indicate a pressure value with the first pressure gauge 42. The first pressure regulating valve 45 can regulate the pressurized water pressure to the water inlet pressure required for subsequent detection.
