Abstract
The utility model provides a flow rate adjusting valve with novel structure-an eccentric micro-adjusting valve which is composed of a valve body, a valve core, a liquid inlet nozzle, a liquid outlet nozzle and a turn knob. The valve body is a cylindrical shell. One end of the valve body is provided with a locating flange on which two blocks are arranged. The valve body is provided with a liquid inlet hole and a liquid outlet hole. The valve core is a cylinder provided with a liquid drain hole. One end of the valve core is provided with a rotary shaft on which a spacing plate provided with a convex part. The cylindrical surface of the valve core is provided with a liquid guiding hole whose both sides are respectively provided with an eccentric liquid guiding groove. The relative positions of the eccentric liquid guiding groove and the liquid inlet hole are varied, which can flexibly and conveniently adjust flow rate.
Description
The utility model has related to valve field, is particularly for the micro-modulating valve of a kind of off-centre, is applicable to the adjusting of fluid flow, and the control valve that is particularly useful for the synthetic fuel kitchen range uses.
Existing fluid trace modulating valve mostly is needle valve structure or ball-valve structure, and ball valve is regulated convenient inadequately, and wayward, needle valve structure is easy to wear, influences the adjusting and the working life of flow.
The purpose of this utility model is to release a kind of simple in structure, regulates flexiblely, and the regulating valve of long service life---eccentric micro-modulating valve to realize the adjusting to the flow flexibility and reliability, is user-friendly to.
Design of the present utility model is when rotating regulating valve, manages to make the bore of valve body inner flow passage that continuous increasing progressively (or successively decreasing) variation takes place, to reach the purpose of continuously adjusting flow rate.
Task of the present utility model is to realize by the way of offering an eccentric grove on cylindrical spool.
Concrete modulating valve is by valve body, spool, feed liquor is chewed, fluid is chewed and is regulated turn-knob and forms, valve body is a cylindrical housings, the one end sealing of housing, the other end is a location flange, having inlet opening and liquid outlet opening on the cylndrical surface of valve body He on the Closed End, spool is the cylindrical body that a center has unidirectional outage, being sliding fit is contained in the valve body, one end of spool is a rotatingshaft, reach outside the housing, the not end of rotatingshaft is equipped with one regulates turn-knob, has a vertical delivery hole on the cylndrical surface of spool, outage in delivery hole and the spool is connected, and with valve body on the inlet opening coupling.Feed liquor is chewed to chew on the cylndrical surface that is located at valve body respectively He on the end face with fluid and is communicated with inlet opening and liquid outlet opening.The runner of modulating valve fluid for from feed liquor chew, inlet opening, chew to liquid outlet opening, fluid through delivery hole, outage.Regulate the relative position of delivery hole and inlet opening, promptly adjustable gate closes size with flow.During use, valve body is fixed on the utensil by flange, rotates turn-knob and can realize regulating.
Have flexibly for the regulation range that enlarges valve makes valve, make things convenient for, reliable micro-regulatory function, the utility model also has following technical characteristics:
1, have radially an eccentric intake chute on the cylndrical surface of spool, intake chute is circumferentially in the both sides of delivery hole, and the groove depth of intake chute is the variation of successively decreasing continuously by middle mind-set both sides, and the sectional shape of intake chute can be a V-type, also can be the U type.
2, the flange on the valve body is the φ type locating flange of a band chucking lug, is provided with two blocks on the front of two chucking lugs of flange.
3, a disc limiting board is housed on the rotatingshaft of spool, limiting board is positioned on the ring end face of locating flange, can rotate with rotatingshaft, and a projection is arranged on the circumference of limiting board.
Eccentric intake chute the regulation range that has enlarged modulating valve is set, realized micro-continuous adjusting.When valve core rotation during to the inlet opening of the delivery hole that makes spool on valve body, feed liquor bore maximum, valve is in the full open state.When the eccentric intake chute on the spool touched inlet opening, the feed liquor bore reduced gradually, and valve is opened little gradually, and flow reduces gradually, and when valve core rotation disappeared to intake chute, the cylndrical surface of spool hid and blocks inlet opening, and valve closing has been realized the purpose of continuous adjusting.
φ type flange on limiting board and the valve body has been formed a limit adjusting mechanism in fact.Limiting board matches with φ type flange, can control the rotation of spool, and promptly the angle of valve core rotation and position are to be limited by two blocks on the flange by limiting board.When limiting board with the projection of valve core rotation on it when arbitrary block on the flange contacts, limiting board is stuck, spool is positioned.Position-limit mechanism in the utility model is design like this, when valve core rotation during to the inlet opening of its delivery hole on valve body, limiting board is just blocked the location by a block on the flange, when spool forwards cylndrical surface that its intake chute do not hold to and touches inlet opening on the valve body, limiting board is blocked the location by another block on the flange, so just make spool only from valve opening (delivery hole) over against inlet opening to valve pool the not termination of (eccentric intake chute) contact in effective length (radian) scope of inlet opening can free rotation continuously, guaranteed to the control fluid flow accurately, effectively, regulate reliably, unlikelyly misoperation occurs.
The utility model is owing to be to be provided with eccentric intake chute to regulate flow on spool, thus make modulating valve have simple in structure, regulate advantages such as flexible, easy to operate, long service life.
Specific embodiment of the utility model is provided by following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the C of Fig. 1 is to view
Fig. 3 is the A-A view of Fig. 1
Below in conjunction with accompanying drawing the utility model being done a step describes:
