Description of drawings
Shown in Figure 1 is the structural representation of the pitch metering control of the present invention's first preferred embodiment.
Shown in Figure 2 is the structural representation of the pitch metering control of the present invention's second preferred embodiment.
The another kind of structural representation of the drop baffle-box of the pitch metering control for first, second preferred embodiment of the present invention shown in Figure 3.
Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
See also Fig. 1, the present invention's first preferred embodiment provides a kind of pitch metering control, and it comprises bitumenpump 1, drop baffle-box and pitch weigh tank 3.
This bitumenpump 1 is connected with this a drop baffle-box and a pitch storage tank.This bitumenpump 1 is used for carrying pitch to this drop baffle-box.
This drop baffle-box comprises casing 21, input channel 22, first output channel 23 and second output channel 24.The pitch of using when this casing 21 is used to store smart the title.This input channel 22 connects this casing 21 and this bitumenpump 1, so that the pitch of being carried by this bitumenpump 1 gets in this casing 21 through this input channel 22.Preferably, this input channel 22 is connected the top of this casing 21.In this input channel 22, be provided with non-return valve 221, this non-return valve 221 can prevent that the pitch in this input channel 22 is back in this bitumenpump 1 to cause the damage of this bitumenpump 1 when this bitumenpump 1 quits work.This first output channel 23 is the thick pipeline of claiming, the one of which end is connected with this casing 21.Preferably, an end of this first output channel 23 is connected the top of this casing 21.This second output channel 24 is the smart pipeline of claiming, the one of which end is connected with this casing 21.Preferably, an end of this second output channel 24 is connected the bottom of this casing 21.The caliber of this second output channel 24 is less than this input channel 22 and this first output channel 23.This second output channel 24 is provided with the smart valve 241 of claiming, this essence claims that the bore of valve 241 is less, and it can accurately control the pitch flow that flows out from this second output channel 24, to reach the smart purpose of claiming.
The below that this pitch weigh tank 3 is arranged at this casing 21 makes this first output channel 23 and this second output channel 24 align mutually with this pitch weigh tank 3.This pitch weigh tank 3 is used to measure the pitch from this first output channel 23 and 24 outflows of this second output channel.
When using this pitch metering control, at first close this essence and claim valve 241.Then, start this bitumenpump 1, pitch is stored in this casing 1 said pitch because non-return valve 221 is washed in the effect of this bitumenpump 1 open from this pitch storage tank carry to this input channel 22.After the pitch in this casing 1 filled with, said pitch flowed out from this first output channel 23 and flows in this pitch weigh tank 3, and carried out weighing by this pitch weigh tank 3.When the weight of said pitch reaches thick title value, then stop the work of this bitumenpump 1, because the effect of this non-return valve 221, pitch can not reflux from pipeline 22.Then, should essence claim that valve 241 opens, the pitch in this casing 1 is flowed in these pitch weigh tanks 3 through this second output channel 24.Again should essence when the weight of said pitch reaches smart title value claim that valve 241 closes to accomplish the metering of pitch.The difference of desired value and smart title value is the lead of closing the door, and is also referred to as drop.
The another kind of method of using this pitch metering control is: at first open and should essence claim valve 241.Then, start this bitumenpump 1, from this pitch storage tank, pitch is carried to this input channel 22, said pitch is stored in this casing 1 also flows out to this pitch weigh tank 3 from this second output channel 24 simultaneously by this bitumenpump 1.After the pitch in this casing 1 filled with, said pitch flowed out from this first output channel 23 simultaneously and flows in this pitch weigh tank 3, and carries out weighing by this pitch weigh tank 3., the weight of said pitch then stops the work of this bitumenpump 1 when reaching thick title value.Therefore, pitch stops from this first output channel 23, to flow into this pitch weigh tank 3.But said pitch continues to flow into this pitch weigh tank 3 from this second output channel 24.Again should essence when the weight of said pitch reaches smart title value claim that valve 241 closes to accomplish the metering of pitch.
See also Fig. 2; The pitch metering control of the present invention's second preferred embodiment and the pitch metering control of first preferred embodiment are roughly the same; Difference is: the non-return valve 221 usefulness T-valve 222 in this input channel 22 substitute; And on another valve port of this T-valve 222, be provided with reflux line 4, promptly this T-valve 222 is arranged on the joint portion of this input channel 22 and reflux line 4.This bitumenpump 1 and this reflux line 4 are connected with this pitch storage tank.During original state; This T-valve 222 ends this input channel 22; This bitumenpump 1 is connected with this reflux line 4; This bitumenpump 1 is opened the back and from this pitch storage tank, is sucked pitch, and this T-valve 222 of process and this reflux line 4 flow back in this pitch storage tank again and circulate to form, and therefore this pitch storage tank medium pitch are stirred.In addition, this bitumenpump 1 can be in starting state at work always, and need not to consider that pitch is back to from this input channel 22 in this bitumenpump 1 to cause the damage of this bitumenpump 1.For taking place only to control this T-valve 222, anti-backflow gets final product; Can this reflux line 4 be connected with this bitumenpump 1 through this T-valve 222; This input channel 22 is ended; This bitumenpump 1 flows into the pitch of carrying in this pitch storage tank through this T-valve 222 and this reflux line 4 again, therefore can avoid the switching between startup, halted state continually of this bitumenpump 1, can prolong the serviceable life of this bitumenpump 1.When this bitumenpump 1 of needs when this casing 21 is carried pitches, this T-valve 222 is communicated with this bitumenpump 1 and this input channel 22, this reflux line 4 is ended, so pitch flows in these casings 21 through this T-valve 222 and this input channel 22.
Pitch metering control of the present invention is simple in structure, practical, only just can accomplish the accurate measurement of pitch with a small-bore smart valve 241 of claiming in the smart title process, and frequency-converting control device and double valve installation cost are lower relatively, and control procedure is simple.
See also Fig. 3, be appreciated that this input channel 22 and this first output channel 23 can also be connected on the sidewall of adjacent top of this casing 21.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
