Technical field
The utility model relates to field of mechanical technique, in particular to a kind of combined valve.
Background technology
Along with the development of power technology, gas-insulated switch GIS has obtained increasingly extensive application.At present the gas of filling among the GIS is generally SF6 (sulfur hexafluoride), and that this gas has is nontoxic, non-stimulated, chemical property stable and character such as dielectric strength height.Carrying out GIS when safeguarding, need carry out every test to the SF6 among the GIS, for example SF6 gas purity, micro-water content, hydrogen fluoride content, hydrogen sulfide content etc.The testing tool of these projects uses different fluid access interface.
According to existing way, GIS is being carried out SF6 when test, by the aperture of manual control GIS gas test venting outlet, make the pressure of gas satisfy the requirement of testing tool.But manually be difficult to control exactly the aperture of venting outlet, thereby also can't accurately control the pressure of the SF6 gas that is input to testing tool.In addition, use various adapters when GIS is connected with testing tool, every kind of first end of switching adapts to the gas detection gas outlet of GIS, and the other end adapts to a kind of fluid access interface of testing tool, need change adapter when changing test event, testing efficiency is lower.
Manually be difficult to accurately control tested gaseous tension and the lower problem of testing efficiency at of the prior art, do not propose effective solution at present as yet.
The utility model content
The purpose of this utility model is to provide a kind of combined valve, manually is difficult to accurately control tested gaseous tension and the lower problem of testing efficiency to solve in the prior art.
For addressing the above problem, the utility model provides following technical scheme:
A kind of combined valve comprises inlet valve and outlet valve, and wherein, described inlet valve and described outlet valve interconnect, and described combined valve also comprises piezometer, and wherein, described piezometer is communicated with described inlet valve and described outlet valve.
Preferably, described combined valve has a plurality of described outlet valves.
Preferably, described combined valve has the column cavity, and wherein, described inlet valve, outlet valve and described piezometer are communicated with by described column cavity.
Preferably, described inlet valve and described piezometer are connected to the two ends of described column cavity, and described outlet valve is connected in the middle part of described column cavity.
Preferably, the axis of described outlet valve is vertical with the axis of described inlet valve.
Preferably, in described a plurality of outlet valves, the fluid output port of each outlet valve is equipped with adapter, and each described adapter adapts to a kind of fluid access interface of fluid detection equipment respectively.
Preferably, described inlet valve and described outlet valve are gas valves.
By the utility model, by piezometer is installed, thereby can control the flow of tested gas comparatively exactly on valve; By using a plurality of outlet valves, can carry out multinomial test simultaneously, improved the test effect.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of structural representation according to combined valve among the utility model embodiment;
Fig. 2 is the another kind of structural representation according to combined valve among the utility model embodiment.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is a kind of structural representation according to combined valve among the utility model embodiment.
Combined valve shown in Figure 1 comprises inlet valve 11, outlet valve 12 and piezometer 13, and inlet valve 11, outlet valve 12 are communicated with between the two, and piezometer 13 is communicated with inlet valve 11.Piezometer 13 also is communicated with outlet valve 12 as can be seen.Like this, the registration of reference pressure meter in the aperture of regulating inlet valve 11 and outlet valve 12 just can be regulated the pressure that outlet valve 12 is exported fluids comparatively exactly.The fluid outlet of outlet valve 12 can connect adapter, to realize and being connected of fluid detection equipment.
Fig. 2 is the another kind of structural representation according to combined valve among the utility model embodiment.
Combined valve as shown in Figure 2 wherein comprises a column cavity 14, and inlet valve 11, outlet valve 12 and piezometer 13 are connected with column cavity 14 respectively, thereby is communicated with by column cavity 14.Combined valve both can comprise an outlet valve in the present embodiment, also can comprise a plurality of outlet valves.Fig. 2 shows the situation of 4 outlet valves.4 outlet valves 12 among Fig. 2 all are communicated with inlet valve 11, can connect a plurality of fluid detection equipment simultaneously like this when test, help to improve testing efficiency.And this mode can reduce tested gas use amount, reduces the maintenance cost of equipment.In Fig. 2, inlet valve 11 and piezometer 13 are connected to the two ends of column cavity 14, and 4 outlet valves 12 are connected in the middle part of column cavity 14.The axis of 4 outlet valves 12 can be vertical with the axis of inlet valve 11.
For combined valve shown in Figure 2, the fluid output port of wherein a plurality of outlet valves 12 can be to be separately installed with adapter, and each adapter adapts to a kind of fluid access interface of fluid detection equipment.When test, need not to prepare separately adapter like this, but directly a plurality of fluid detection equipment are connected with combined valve.If be used for test gas insulation combined switch GIS SF6 gas, the fluid detection equipment so here can be instruments such as gas purity detector, micro-water content detector, hydrogen fluoride content detector and hydrogen sulfide content detector.
The usable range of the combined valve in the present embodiment is not limited to the detection of SF6 gas, also can be used in the detection occasion of other gases.Combined valve in the present embodiment also can be used for the occasion that fluid is a liquid in addition, and inlet valve in the combined valve and outlet valve need adopt the corresponding liquid valve in this case, and piezometer is replaced by hydraulic ga(u)ge.
From above description, as can be seen, use the technical scheme of present embodiment, in combined valve, the inlet valve and the outlet valve that interconnect by setting, and the piezometer that setting is communicated with inlet valve enters the pressure of the fluid of valve with detection, thereby can control the amount of the fluid that enters valve comparatively exactly.And the combined valve in the present embodiment can comprise a plurality of outlet valves, can export the fluid that inlet valve is introduced to a plurality of carriers for example proving installation, thereby improve the efficient of associative operation, and the use amount that helps to save fluid.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
