Abstract
The invention discloses a flow regulating device comprising a case and a regulating piece, wherein a water channel is arranged in the case and is a stepped hole, the stepped hole is provided with a step plane which is fixedly provided with a plurality of bulged bases thereon, and an interval is formed between two adjacent bulged bases. The regulating piece is made of an elastic material and can carry out elastic deformation under stress; the regulating piece is installed in the case and is arranged on the bulged base; spaces above the step plane, below the regulating piece and between two adjacent bulged bases form the water passing port of the water channel; and the elastic deformation of the regulating piece is regulated to press parts of the regulating piece into the water passing port so as to change the water passing section area of the water passing port. The invention has the advantages that the regulating piece is arranged above the bulged base, and the bottom surface of the regulating piece, which corresponds to the water passing port, has no support; the direction of the elastic deformation of the regulating piece is the same with flow direction, so that the regulating piece has big elastic deformation, wide water amount regulating range, high sensitivity for the elastic deformation aiming at pressure change and high regulating veracity.
Description
Technical field
The present invention relates to a kind of flow regulator.
Background technique
Early stage flow regulator mainly comprises a housing, a Sealing and a spring; Said housing has one and crosses water channel; Said Sealing was arranged within the water channel; Said spring top is against between Sealing and the housing, crosses the flow of water channel through the relative Sliding Control of crossing water channel of Sealing.When hydraulic pressure during greater than predetermined pressure, said Sealing is slided towards postive direction by hydraulic action and crossed the water section area with what reduce water channel, reduced the flow of water channel, and pressure spring is with energy storage in the sliding process; When hydraulic pressure during less than predetermined pressure, said energy storage spring release can, and drive Sealing and slide in the opposite direction and crossed the water section area with what increase water channel, increased the flow of water channel.Because controlling device comprises Sealing and spring, so complex structure, it is big to take up room.
To above-mentioned deficiency, the someone has proposed solution, and having announced the patent No. like the Chinese patent database on March 10th, 2010 is 200920137849.8 the denomination of invention model utility for " Flow-rate adjustment check valve ".It comprises a sleeve, a current-limiting apparatus and an one-way valve.Said current-limiting apparatus is arranged on the feed-water end of sleeve, and it comprises a water-saving sheet and a water-saving plate rack.The ring segment that said water-saving plate rack comprises an overcoat, cover and is fixed together overcoat and interior cover in one offers the water port on the said ring segment.Cover and corresponding water port in the socket of said water-saving sheet, are regulated with control flow rate with control water port section area through the distortion of hydraulic action control water-saving sheet.It has following deficiency: 1. because said water-saving sheet is supported by at ring segment, and said ring segment is the plane basically, therefore the amount of deformation of said water-saving sheet is little, and water yield regulation range is little, and is not high to the distortion sensitivity of variation in water pressure, and the adjusting accuracy is lower; 2. the deformation direction owing to said water-saving sheet is vertical with the hydraulic pressure direction, so amount of deformation is little, and water yield regulation range is little, and is not high to the distortion sensitivity of variation in water pressure, and the adjusting accuracy is lower.
Summary of the invention
The invention provides a kind of flow regulator, it has overcome the existing deficiency of the flow regulator in the background technique.
The technological scheme that is adopted that the present invention solves its technical problem is:
Flow regulator, it comprises:
One housing was provided with water channel in it, said water channel excessively is a shoulder hole, and said shoulder hole has ladder surface, is installed with some boss on the said ladder surface, had at interval between said every adjacent two boss; And
One adjusting element; Its material is an elastic material and can resiliently deformable when stressed; It is installed within the housing and is placed on the boss; Became the mouth of a river excessively of water channel on the ladder surface, under the adjusting element and the space between every adjacent two boss, and can make adjusting element partly be pressed into the mouth of a river through the adjusting element resiliently deformable to change the water section area excessively at the mouth of a river.
Among one preferred embodiment: said adjusting element is a sheet.
Among one preferred embodiment:
Said shoulder hole also has a pilot hole and a through flow hole, and said pilot hole diameter is greater than the through flow hole diameter;
Leave the gap between said adjusting element and the pilot hole inner side surface.
Among one preferred embodiment: said boss becomes rib, and, have at least the inner of a pair of said rib to stretch out and be fixed together, the outer end of said rib is fixed in the pilot hole inner side surface.
Among one preferred embodiment: convex with positioning table on the outer end of said rib, said positioning table is circular layout; Said adjusting element is placed on the rib, and adaptive within the annular that said positioning table is arranged.
Among one preferred embodiment: be installed with at least one protruding platform between adjacent two boss on the said ladder surface, leave between said protruding platform and the boss at interval.
Among one preferred embodiment: it also comprises:
One limit is taken off part, and it is fixed in housing, and said limit is taken off and offered the penetration hole that axially runs through on the part, and said adjusting element takes off between the part at boss and limit.
Among one preferred embodiment: it also comprises:
One limit is taken off part, and it is movably connected in housing, can take off the part of the activity regulating and controlling relatively elastic deformation level between part and the housing through limit, and said limit is taken off and offered the penetration hole that axially runs through on the part.
Among one preferred embodiment: turning surface is provided with internal thread within the said shoulder hole, and said limit takes off that turning surface is provided with outside thread outside the part, and said limit is taken off part and is screwed onto shoulder hole, and said limit takes off that part flexibly connects housing and adjusting element is supported on the top.
Among one preferred embodiment: it is adaptive and be slidingly connected within the shoulder hole that said limit is taken off part, and shoulder hole slides relatively when receiving hydraulic action.
The present technique scheme is compared with background technique, and it has following advantage:
1. be placed on the boss owing to adjusting element; The correspondence of adjusting element is crossed the bottom surface at the mouth of a river does not have support; Because the resiliently deformable direction of adjusting element and water (flow) direction are in the same way, so the elastic deformation amount of adjusting element is big, water yield regulation range is big; Resiliently deformable to variation in pressure is highly sensitive, regulates the accuracy height;
2. leave the gap between adjusting element and the pilot hole inner side surface, therefore can avoid the complete blocking water flow of adjusting element;
3. limit is taken off part and is screwed onto shoulder hole, and limit is taken off the part top and supported adjusting element, so the user can the manual tune flow, and the relation between Flow-rate adjustment and the adjusting element elastic deformation amount can be set;
4. the inner of said rib is stretched out and is fixed together, then can the stable support adjusting element, and can avoid the adjusting element center to be out of shape downwards, prevent the adjusting element release unit;
5. adjusting element is placed on the rib and is adaptive within the annular that said positioning table is arranged, can locate adjusting element;
6. be installed with a protruding platform between adjacent two boss, leave between protruding platform and the boss at interval, protruding platform can be avoided the adjusting element excessive deformation.
