Embodiment
Illustrate that the invention will be further described with embodiment below in conjunction with accompanying drawing.
Fig. 1, Fig. 2, in Fig. 3, self-supporting temperature control part 1 utilizes heated liquid to expand and the incompressible principle of liquid realizes automatically regulating, comprise final controlling element assembly 101, capillary tube 105, liquid temperature-sensitive bag 106, gate valve and spring 102, liquid temperature-sensitive bag 106 is placed in the water intake of valve body 4, one end of capillary tube 105 is communicated with liquid temperature-sensitive bag 106, the other end connecting tube final controlling element assembly 101, spring 102 is socketed on gate valve, gate valve comprises valve rod 103 and valve plate 104, valve plate 104 is connected to the lower end of valve rod 103, the upper end of valve rod 103 is communicated with final controlling element assembly 101, valve plate 104 connects with autompulse stream scouring part 2.Packing wherein in liquid temperature-sensitive bag 106 is fluid wax.Temperature variation causes the long-pending change of temperature-sensitive bag 106 internal liquid thus, and this change is delivered in final controlling element by capillary tube 105, can the stroke of regulating valve stem 103, and then regulating valve flow.When temperature raises, the fluid wax of expansion promotes valve rod 103 and moves downward, and flow reduces; When temperature reduces, fluid wax volume declines, and spring 102 promotes valve rod 103 and moves upward, and is increased by the flow of valve, thus realizes self-supporting temperature control adjustment.
Because circulating water in body needs not arrhea dynamic, and have a minimum flow and maximum flow (being determined by the circulating water temperature scope of ingress), so valve rod 103 stroke of temperature-controlled portion 1 also has a stroke range, and it can not be closed completely, so the seal approach that spool place is not unnecessary, take seal approach at spring 102 place cavity and flow channel place, anti-sealing enters spring 102 place cavity and reduces service life of equipment.The incomplete closed channel of spool, reduces the difficulty of opening and closing.Take the spool of gate valve, the pressure drag that current produce is very little on the spool impact that moves up and down, and the resistance of the valve core movement reduced further, makes valve core movement be more prone to control, also more accurate.For the pipeline of different flow, can by changing thermometer bulb 106 size, valve rod 103 length and spring 102 [coefficient of realize different requirements.
Containing more impurity in industrial circulating water, when water velocity is less in the duct, easily fouling in the duct, has a strong impact on the efficiency of heat exchange.And ducted Fouling Cleaning is very complicated, cost is also very large, so it is very important for carrying out that timing washes away to pipeline.But heat transmission equipment is very many in a petrochemical plant, if washed away by manually completing, not only workload is huge, and there is potential safety hazard, and automatic flushing system can well address these problems.
In Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7, stream scouring part 2 comprises the first flow channel 204, second flow channel 205, impeller 202, connecting rod 201 and baffle plate 203, first flow channel 204 flows through temperature-controlled portion 1, control by temperature, second flow channel 205 flows through flushing system, completes and washes away function; Impeller 202, connecting rod 201 and baffle plate 203 form slidercrank mechanism, and impeller 202 is arranged on flow inlet place, and baffle plate 203 coordinates the second flow channel 205 water outlet, block the second flow channel 205 water outlet for indirect; Connecting rod 201 one end is movably connected in the edge of impeller 202, and the other end is movably connected on baffle plate 203; Current are when impeller 202, impact force is produced to impeller 202, impeller 202 rotates, impeller 202 be rotated through the straight line motion that connecting rod 201 is converted into baffle plate 203, make the water velocity in passage be in the scope of a change, produce pulsatile effect, dirt is not easily deposited, thus greatly reduce scaling rate, extend the working life of whole equipment.
For utilizing water flow impact pressure to greatest extent, washing away branch road water intake and having done specialized designs, most current of inflow branch road are flowed into along impeller 202 tangent direction, and make impact force become large as much as possible, impeller 202 is rotated.Impeller 202 has two, as shown in the figure, current can be allowed like this to have larger impact area, impact force is made to become large as much as possible, centre is connected by the revolute pair at connecting rod 201 place, as shown in the figure, the central shaft of two impellers 202 does not link together, and mechanism operates normally not have unnecessary constraint ensure when connecting rod 201 can be allowed like this to move.
Washing away function is realized by the motion of baffle plate 203.The structure shape of baffle plate 203 is extremely important.As shown in the figure, insert guide rail in the circular hole 206 in the middle of baffle plate 203, to ensure baffle plate 203 moving linearly, instead of topple over forward or backward under the effect of connecting rod 201 power; Groove 207 above circular hole 206 is connected with connecting rod 201, and connecting rod 201 can rotate around the axle of centre.The semi-circular through hole on both sides also has certain current to pass through when making baffle plate 203 block water outlet completely, ensures the rotation of impeller 202 and the operation of mechanism.
When temperature control bypass flow is larger, flowing through the flow washing away branch road can be less, may occur the situation that current cannot promote impeller 202 and rotate, total but water flow is now comparatively large, and in pipeline, this is just less scaling, even if impeller 202 does not rotate do not have large impact yet; When temperature control bypass flow is less, flushing system flows through larger flow, and impeller 202 is subject to larger impact force, can normal rotation, forms pulse water flow, causes the change of whole pipe flow speed, reduces the speed of fouling in pipeline.
Scouring part 2 structure is very simple, because the power that current produce is smaller, the structure of too much complexity can produce larger resistance, and mechanism may be caused normally not run.Therefore wash away structure more simple better, and in this mechanism, the different position of baffle plate 203 correspond to different water velocities, and can accomplish open slow and close fast, the amplitude of pulse is increased, and function is washed away in realization preferably.
In Fig. 1, Fig. 2, what barrier portion 3 adopted is adopt stop valve structure now, comprise handwheel 301, screw mandrel 302, valve seat 303, screw mandrel 302 is threadedly engaged in the abutting end of valve body 4, the upper end of screw mandrel 302 is stretched out abutting end and is connected handwheel 301, the lower end connecting valve seat 303 of screw mandrel 302, valve seat 303 is engaged in intercepting water on mouth of valve body 4.
Below be only some embodiments of the present invention, for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to the protection domain of invention.
