A kind of valve by fluid temperature (F.T.) regulation and control fluid trend
Technical field
The utility model relates to chemical industry fluid device field, specifically refers to a kind of valve by fluid temperature (F.T.) regulation and control fluid trend.
Background technique
In the work in chemical plant, the transport of fluid feedstream is absolutely necessary a ring, and some needs the chemical material added, and needs suitable temperature, when dropping into the consersion units such as reactor, could keep good manufacturing efficiency.The existing method making fluid feedstream temperature constant, is at the coated thermal insulation layer of pipeline outer-layer, makes fluid in flow process, not dissipated heat, thus ensures the temperature constant of fluid feedstream.But, a small amount of heat loss how much is had in transport process, and when transporting in pipeline, pipeline own temperature also can cause certain influence to feed liquid, larger adverse effect can be brought to Chemical Manufacture like this, existing processing method, be the feed liquid cooled in pipe is directly released or reclaims again, after feed liquid bulk temperature meets by the time, then added in chemical reaction device, such operation needs operated by personnel mostly, considerably increases the workload of staff.
Model utility content
The purpose of this utility model is to provide one by perception fluid temperature (F.T.), can carry out the valve of automatic control flow check body transporting direction.
The utility model is achieved through the following technical solutions: a kind of valve by fluid temperature (F.T.) regulation and control fluid trend, comprise and fluid inlet tube, fluid go out pipe, go out pipe under fluid, described fluid inlet tube bottom directly with go out pipe under fluid and be connected, be connected in the middle part of fluid inlet tube on fluid to go out to manage; Described fluid goes out inner tube wall and is provided with temp probe, temp probe is connected with outside control system, described control system controls to be located at two-way gear valve fluid going out pipe and fluid inlet tube place, and described two-way gear valve one side is mated with fluid inlet tube passage, another side with fluid goes out pipe and mates.First, two-way gear valve closure fluid inlet tube, overheated or excessively cold fluid enters fluid from fluid inlet tube and goes out pipe, fluid goes out the temperature of the temp probe perception fluid of inner tube wall, its temperature signal is passed to outside control system, perceive fluid temperature (F.T.) constant time, control system controls that two-way gear valve convection cell goes out the pipe mouth of pipe and carries out sealing blocking, make the fluid of temperature constant, go out pipe under flowing directly into fluid by fluid inlet tube, thus enter in chemical reaction container.At the end of fluid transport, control system automatically controls two-way gear jam pot cover and blocks up fluid inlet tube, so moves in circles.
For better realizing the utility model, further, the caliber going out pipe under described fluid inlet tube, fluid going out pipe, fluid is all identical.
For better realizing the utility model, further, outer tube layer is gone out under described fluid inlet tube, fluid going out pipe, fluid all coated by thermal insulation layer.
For better realizing the utility model, further, described temp probe is antidetonation temperature transducer.
For better realizing the utility model, further, described two-way gear valve top layer is anticorrosive sealing gasket.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is by arranging pipeline and valve, can flow through which pipeline by double-direction control fluid, and affect less between pipeline, and circuit design is reasonable, uses and more succinctly facilitates, and indirectly improves chemical plant manufacturing efficiency;
(2) the utility model is by setting up temp probe, and fed-back fluid temperature conditions, to control system, automatically controls two-way gear valve alter by control system and flows to, significantly reduce the workload of staff;
(3) the utility model is by using two-way gear valve, flexibly shutoff fluid can go out pipe and fluid inlet tube, reduce manufacture cost, use more convenient, control more simple, bear little to control system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-fluid inlet tube, 2-fluid goes out pipe, go out pipe under 3-fluid, 4-temp probe, 5-control system, 6-two-way gear valve.
Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristics.Thus, be limited with " first ", " second " only for describing object, and instruction or hint relative importance can not be interpreted as or impliedly comprise one or more these features.In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Also can be directly be connected, also can be indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
Embodiment:
The main structure of the present embodiment, as shown in Figure 1, comprises under fluid inlet tube 1, fluid going out pipe 2, fluid and goes out pipe 3, described fluid inlet tube 1 bottom directly with go out pipe 3 under fluid and be connected, be connected in the middle part of fluid inlet tube 1 on fluid and go out pipe 2; Described fluid goes out pipe 2 inwall and be provided with temp probe 4, temp probe 4 is connected with outside control system 5, described control system 5 controls to be located at the two-way gear valve 6 fluid going out pipe 2 and fluid inlet tube place 1, described two-way gear valve 6 one side is mated with fluid inlet tube 1 passage, another side with fluid goes out pipe 2 and mates.
Concrete workflow: two-way gear valve 6 sealing fluid inlet pipe 1, overheated or excessively cold fluid enters fluid from fluid inlet tube 1 and goes out pipe 2, fluid goes out the temperature of the temp probe 4 perception fluid of pipe 2 inwall, its temperature signal is passed to outside control system 5, perceive fluid temperature (F.T.) constant time, control system 5 controls two-way gear valve 6 and carries out sealing blocking by fluid going out pipe 2 mouth of pipe, make the fluid of temperature constant, go out pipe 3 under flowing directly into fluid by fluid inlet tube 1, thus enter in chemical reaction container.At the end of fluid transport, control system 5 controls two-way gear valve 6 shutoff fluid inlet tube 1 automatically, so moves in circles.
