Abstract
The invention discloses a method for achieving a purpose for regulating rates of flow precisely through a flow control valve. A handle 1 is connected with a valve element 2, the valve element 2 is connected with a valve cover 3, the valve cover 3 is connected with a valve body 5, a gap formed between the valve element 2 and the valve body 5 is sealed through a sealing ring 4, and a triangular chute 6 is formed in the valve element 2 and is in clearance fit with a circular hole 7 of the valve body 5. A cylinder of the triangular chute 6 is in clearance fit with the circular hole 7. The triangular chute 6 becomes smaller from the end face, and the length of the triangular chute 6 is smaller than the diameter of the circular hole 7 by about 71mm. When the handle 1 is rotated, the triangular chute 6 rotates and moves inside the circular hole 7, small triangular holes with different sizes are formed by the triangular chute 6 and the end face of the circular hole 7, different rates of flow are formed, a linear function is formed by the variation of the rates of flow and the regulating variable of the handle 1, and the rates of flow can be precisely regulated.
Description
Technical field the present invention relates to a kind of automobile ternary/gas handling system and detects the implementation method of the flow control valve of cleaning equipment to the meticulous adjusting of flow, concretely, is a kind of implementation method of ternary and air inlet washing agent flow being carried out to meticulous thin tuning.
Background technique is along with the rapid growth of China's economic, and automobile pollution increases in the annual speed with millions of of China.As the intake valve of motor car engine, through using for a long time, if can not clean in time, will cause deficiency of air, incomplete combustion, cause waste of fuel, the engine power deficiency; And as the three-element catalytic parts in automobile exhaust system, cleaning is not carried out in long-term use can make three-element catalytic usefulness reduce, harmful gas in tail gas decomposes to be discharged in air through three-element catalytic and causes environmental pollution, simultaneously the exhaust of automobile is also caused not freely, affects engine performance.The present invention is used on the cleaning equipment of automobile ternary/gas handling system, can to automobile ternary/gas handling system, clean better.
The Flow-rate adjustment valve core adopted in present cleaning equipment on the market is all that cone coordinates with the circular hole on valve body, in the Spool rotating process, form with the circular hole of valve body the circular crosssection varied in size, liquid is flow through by toroidal surface, plays the effect to Flow-rate adjustment; But the structure of this kind valve makes flow become quadratic function relation with the aperture of modulating valve, and namely the quadratic function of annulus area, cause flow change rate excessive, can not carry out meticulous adjusting to flow.
Summary of the invention the present invention aims to provide the implementation method of a kind of flow control valve to the meticulous adjusting of flow, solves the flow control valve problem excessive to the Flow-rate adjustment variance ratio in the past, reaches the purpose of the meticulous adjusting of flow.
The Flow-rate adjustment of flow control valve is mainly to realize by the adjusting washing agent flows through in flow control valve gap length; By the structure to flow control valve, design, the gap variable quantity that washing agent can be flow through reduces, and reaches the purpose of the meticulous adjusting of flow; The present invention changes washing agent flows through in flow control valve gap into triangle, make the variable quantity of the gap length that washing agent passes through by the variable quantity of the quadratic function of original annulus area, be become the variable quantity of the linear function of triangle area, reach the purpose to the meticulous adjusting of washing agent flow.
The technological scheme that the present invention takes is as follows:
A kind of flow control valve structure, comprise handle, spool, valve gap, seal ring and valve body, on spool, process triangular chute, the triangular chute of spool is arranged in the circular hole of valve body, handle is connected with spool, when handle with sleeve carries out Flow-rate adjustment, the Spool rotating motion, the end face of the triangular chute of spool and the circular hole of valve body can form the triangle gap varied in size, liquid is flow through by the triangle gap, the flow that formation varies in size, the variation of flow is namely the variation of triangle area, realized that washing agent is passed through in flow control valve gap is become the variation of triangle area by the area change of annulus, even the variation of washing agent flow becomes the linear function curve by original quadratic function, reached the purpose to the meticulous adjusting of washing agent flow.
The implementation method of a kind of flow control valve to the meticulous adjusting of flow is characterized in that comprising the following steps:
A, handle are connected with spool, are used for making the Spool rotating motion.
B, valve gap are installed on valve body, on the spool of valve gap inboard, seal ring are installed, and seal.
C, spool and valve body flow through at washing agent the Spielpassung that place adopts axis hole, and process triangular chute on spool herein, triangular chute starts from large to small from the end face of spool, the length of triangular chute is less than the length 1mm left and right of valve body circular hole, when spool rotatablely moves in valve body, the end face of triangular chute and circular hole forms the triangle gap varied in size, and the washing agent triangle is flow through by gap, reaches the purpose to the meticulous adjusting of washing agent flow.
Good effect of the present invention is:
(1) spool and valve body adopt the Spielpassung in axle and hole, and flow is diminished.
(2) on spool, process triangular chute, uninterrupted is determined by the area of triangular chute.
(3) length of the triangular chute on spool is less than the length 1mm left and right of circular hole on valve body, guarantees that the tail end of the triangular chute on spool when flow control valve cuts out can, fully in the circular hole of valve body, be realized closing of flow control valve.
The accompanying drawing explanation
Fig. 1 is the flow control valve erection drawing that ternary/gas handling system detects cleaning equipment;
The triangle gap figure of Fig. 2 different sizes that to be the spool triangular chute form from the circular hole of valve body.
Embodiment further illustrates the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the implement device of a kind of flow control valve to the meticulous adjusting of flow, handle 1 is connected with spool 2, and spool 2 is connected with valve gap 3 by screw thread, and valve gap 3 is connected on valve body 5, in valve gap 3 inboards, seal ring 4 is installed on spool 2, and the gap of 5 of spool 2 and valve bodies is sealed, and does not allow liquid be leaked by valve gap 3 places, on the fitting surface of core valve 2 and the circular hole of valve body 5, open triangular chute 6 and with circular hole 7 Spielpassung of valve body 5, but gap value can not make liquid pass through.
As shown in Figure 2, a kind of flow control valve coordinates the meticulous adjusting to flow to the spool 2 of the implement device of the meticulous adjusting of flow with valve body 5, the cylinder of the triangular chute 6 of spool 2 processing with and valve body 5 on circular hole 7 Spielpassung, triangular chute 6 is started from large to small by end face, the length of triangular chute 6 need be less than the length 1mm left and right of circular hole 7, when handle with sleeve 1, triangular chute 6 on spool 2 is interior in rotary moving at the circular hole 7 of valve body 5, triangular chute 6 forms with the end face of circular hole 7 the triangle gap varied in size, washing agent is flow through by the triangle gap, the flow that formation varies in size, and the variation that is changed to triangle area of flow, the linear function relation that is adjusted to handle 1, reach the purpose to the meticulous adjusting of washing agent flow.
