The flow controller is further characterized in that the flow controller is provided with a bevel, and an adjusting sheet is arranged on the bevel and used for controlling the auxiliary runners which are opened and closed under the pressure of the fluid flowing through the auxiliary runners.
Description
Technical field
The present invention relates to a kind of flow dontroller, particularly a kind ofly adopt elastic material to prepare and the flow dontroller that can close when hydrodynamic pressure rises of accessory channel.
Background technique
The flow dontroller of prior art, it can realize under the increasing pressure, controls the maximum value that flow reaches a regulation, namely along with the rising flow of hydrodynamic pressure rises, when flow arrives the maximum value of this regulation, when pressure rises again, flow no longer rises.The flow dontroller of this prophet has the following disadvantages, one: when low pressure, cannot reach the maximum value that flow specifies faster; Its two: reach the maximum value of regulation at flow after, along with the rising of pressure, its flow there will be decline, further, there will be larger noise.
Summary of the invention
By flow dontroller of the present invention, above-mentioned shortcoming can be solved, thus realize other advantage being about to description.Flow dontroller of the present invention, adopt elastomer material one-body molded, comprise the sprue that is arranged at neutral position, some auxiliary flows being arranged at this sprue periphery, described flow dontroller is configured with an inclined-plane, this inclined-plane controls the sprue changed under the hydrodynamic pressure flow through, described inclined-plane is provided with an adjustment sheet, this adjustment sheet controls the auxiliary flow of opening and closing under the hydrodynamic pressure flow through, thus realize the maximum quick rising of flow being reached to a regulation, further, export along with pressure increase reaches a stable maximum value flow.Object of the present invention reaches by following technical solution:
A kind of flow dontroller.Adopt elastomer material one-body molded, comprise the sprue that is arranged at neutral position, some auxiliary flows being arranged at this sprue periphery, it is characterized in that: described flow dontroller is configured with an inclined-plane, this inclined-plane controls the sprue changed under the hydrodynamic pressure flow through, described inclined-plane is provided with an adjustment sheet, this adjustment sheet controls the auxiliary flow of opening and closing under the hydrodynamic pressure flow through.
Further, described flow dontroller, it has a center line, and the power of the fluid matasomatism flow through on inclined-plane is towards center line.
Further, each auxiliary flow distance center line has equal distance.
The present invention contrasts prior art following remarkable advantage:
1. adopt elastomer material one-body molded, cost is low, and manufacturing efficiency is high;
2. sprue is arranged at flow dontroller neutral position, and realized the control of sprue by the inside pressure change of hydrodynamic pressure to inclined-plane, the flow being is more stable, and noise is less;
3. accessory channel is can realize cutting out at high pressure, ensure can to make under lower pressure flow reach fast regulation maximum value and under high pressure flow can not exceed default maximum value.

Embodiment
Now the present invention is further described with embodiment by reference to the accompanying drawings.
Basic ideas of the present invention are that flow dontroller is configured with an inclined-plane, this inclined-plane controls the sprue changed under the hydrodynamic pressure flow through, described inclined-plane is provided with an adjustment sheet, this adjustment sheet controls the auxiliary flow of opening and closing under the hydrodynamic pressure flow through, thus the quick rising realizing flow reaches the maximum value of setting, and in pressure constantly rising situation, the maximum value that this sets can be kept.
Shown in figure 1,2,3,4,5, the flow dontroller 1,2,3,4 of different embodiment, it can be installed in the front position preset of here unshowned sanitary equipment, flow through ducted fluid in this unshowned sanitary equipment first by described flow dontroller 1,2,3,4 after flow into the miscellaneous part of this sanitary equipment again.
Flow dontroller 1, 2, 3, 4 for this reason for also making the flow flow through in time per unit arrive the maximum value of setting fast fast when the hydrodynamic pressure flowed into is very little, further, even if the maximum value that also flow control flow through in time per unit can be specified when the pressure of increasing incoming fluid, flow dontroller 1, 2, 3, 4 adopt elastomer material one-body molded for this reason, it comprises the sprue 5 that is arranged at neutral position, some auxiliary flows 7 being arranged at this sprue 5 periphery, described flow dontroller is configured with an inclined-plane 6, this inclined-plane 6 controls the sprue 5 changed under the hydrodynamic pressure flow through, described inclined-plane 7 is provided with an adjustment sheet 8, this adjustment sheet 8 controls the auxiliary flow 7 of opening and closing under the hydrodynamic pressure flow through.
Described flow dontroller 1,2,3,4 has a center line 12, this center line 12 forms with inclined-plane 6 angle that is less than 90 °, make the fluid matasomatism that the flows through power on inclined-plane 6 towards center line, ensure that along direction of flow, sprue 5 front end the most easily reduces distortion.
Described inclined-plane 6 is provided with an adjustment sheet 8, this adjustment sheet 8 forms for rotating around center line 12, because auxiliary flow 7 distance center line 12 is by equal distance, so along with the rising of hydrodynamic pressure, adjustment sheet 8, along direction of flow distortion, finally closes auxiliary flow 7 completely.
Fig. 7 is the embodiment that the arbitrary flow dontroller 1,2,3,4 illustrated of Fig. 1 to Fig. 5 configures base 9, described flow control 1,2,3,4 can directly be installed in the default front position of sanitary equipment, also can configure base 9 and be installed on the default front position of sanitary equipment again, when base 9 pre-installed by flow dontroller 1,2,3,4, this base offers in sprue 5 relevant position the hole 10 that does not affect fluid flow along direction of flow, further, this base offers in auxiliary flow 7 relevant position the hole 11 that affects fluid flow along direction of flow.
The working method of flow dontroller of the present invention is: this flow dontroller 1,2,3,4 is installed in the default front position of sanitary equipment, when the hydrodynamic pressure flowed through is less than the close value of default auxiliary flow 7, fluid passes through from sprue 5 and auxiliary flow 7, when the hydrodynamic pressure flowed through is equal to or greater than the close value of default auxiliary flow 7, auxiliary flow 7 is closed, and fluid only passes through from sprue 5.
Therefore, inventive flow controller can not only well be guaranteed the flow flow through in time per unit also can be made fast to arrive the maximum value of setting fast when the hydrodynamic pressure flowed into is very little, further, even if the maximum value that also flow control flow through in time per unit can be specified when the pressure of increasing incoming fluid, and can be good at control noise.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
