Abstract
The utility model provides a self-force type flowrate-adjusting control valve used for controlling the liquid flowrate of liquid transfer pipe networks. A self-balanced valve set and a manual regulation valve set are connected in a valve body, a longitudinal middle axial line matched and connected with two valve sets is the same axial line which is vertical to medium flow direction in the valve body, and an automatic valve plug tightly matched and connected in a sleeve barrel in the self-balanced valve set is a sleeve barrel throttling window type automatic valve plug of which the perisporium is provided with throttling windows. The utility model has the advantages of novel structure, stable pressure in the valve, high precision of controlling flowrate and simple convenient use, and the utility model is a novel flowrate-adjusting control valve and can be used for the flowrate control of various liquid transfer pipe networks and heat supply pipe networks.
Description
(1) technical field
The utility model relates to a kind of valve, especially a kind of flow regulating and controlling valve that is used for FLUID TRANSPORTATION pipe network control flow rate.
(2) background technique
In the pipe network of FLUID TRANSPORTATION, the actual flow of pressing controlled pipeline needs, and disposable setting flow will be equipped with flow control valve usually.In known technology, automatic balancing valve and manual tune gate valve that existing flow control valve mainly is made up of valve body, spool, spring, pressure-sensitive diaphragm, automatic valve plug, valve plug sleeve.Because existing flow control valve is to adopt the corresponding interworking structure with manual modulation valve of automatic balancing valve, especially the automatic valve plug structure in the valve reaches unreasonable with cooperating of valve plug sleeve, make valve plug be subjected to force unbalance, off state amount of leakage big, thereby causing self-acting valve to fill in the mouth of a river and manually operated valve, to regulate the variation of flow asynchronous, also be prone to valve plug internal pressure pulsation phenomenon, its noise is big, and the control flow rate precision is low, makes troubles to use.
(3) summary of the invention
The utility model is at the above-mentioned technical problem that existing flow control valve exists, its objective is provide a kind of novel structure, reasonable in design, the valve internal pressure stable, noise is low, control flow rate precision height, New Type Flow Control Valve easy to use.
For achieving the above object, the technological scheme that the utility model is taked is: integrate automatic balancing valve group and this double-valve structure of manual modulation valve group and be total to load in valve body, and two valve groups join the longitudinal central axis line that connects be with valve in the perpendicular same axis of media flow direction, the automatic valve plug that close fit connects in the automatic balancing valve group middle sleeve is the automatic valve plug of new structure that is shaped on 3～5 uniform trapezoidal throttle window of homalographic on the cock body peripheral wall, and also the design of manual modulation valve group is adopted and rotated double-flashboard new structure, the self-powering type flow regulating and controlling valve that is linked to be for novel of organizing.This valve is to change to rely on oneself by the automatic valve plug of body upper bush throttle window formula, rotary double-flashboard, pressure-sensitive diaphragm and pipeline pressure reduction (pressure) to keep the constant dynamic adjustments valve of control flow rate of setting.Its function is to lock the flow of having set that passes through, and makes the Flow-rate adjustment process of pipe network need not to consider the phase mutual interference of Flow-rate adjustment between take-off line, makes assignment of traffic work become disposable intuitively operation.When this valve uses, can under the working medium hydraulic pressure, eliminate the pressure head more than needed and the caused flow deviation of pressure surge of pipeline automatically, eliminate the ANOMALOUS VARIATIONS of downstream pressure, stablize the operating conditions of controlled pipe network system.
Because the utility model is the composite structure that integrates automatic balancing valve group and this bivalve of manual modulation valve group, and the automatic valve plug of automatic balancing valve group is designed to again be shaped on three trapezoidal window constructions that dam of uniform homalographic at the cock body circumference, make working medium evenly enter autobalance valve plug inner chamber by three throttlings, automatic valve plug stress balance, the interior pressure stablized, also make the adjusting of area change and manual modulation valve of each position of rest of automatic valve plug mutually for synchronously, also the manual modulation valve design is adopted rotation double-flashboard new structure, make the valve rod adjustment stroke with the relation of corresponding adjusting flow be tending towards linear, the double-flashboard structure has also shortened the axial dimension of manual modulation valve greatly, has alleviated the weight of valve.Therefore, self-operated flow control valve of the present utility model compared with prior art, have novel structure, reasonable in design, cooperate closely, the valve internal pressure is stable, noise is low, control flow rate precision height, beneficial effect such as easy to use.It is applicable to various FLUID TRANSPORTATION pipe networks, also is suitable for the flow control of heating network, is a kind of novel flow control valve.

Fig. 2 is the automatic valve plug of automatic balancing valve group among Fig. 1 and the amplification view of tube-in-tube structure.
Fig. 3 is the structure for amplifying diagrammatic sketch of the double-flashboard of manual modulation valve group among Fig. 1.
(5) embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
Embodiment as shown in Figure 1, the utility model is to be fitted with automatic balancing valve group and manual modulation valve group at valve body 2 inner chambers, automatic balancing valve group and manual modulation valve group join altogether the medial axis that connects be with valve body media flow direction be the perpendicular same axis of flow channel for liquids in the valve.The automatic balancing valve group is made up of spring 1, pressure-sensitive diaphragm 4, spool 3, automatic valve plug 6 and valve plug sleeve 5, it is characterized in that the automatic valve plug 6 that close fits connect in the valve plug sleeve 5 is to be shaped on 3～5 (the best is 3) uniform trapezoidal throttle window of homalographic to be consisted of the automatic valve plug of sleeve throttle window formula (seeing accompanying drawing 2) on valve plug cock body peripheral wall.The manual modulation valve group is made up of valve seat 8, regulating valve stem 9, rotation flashboard 7 and flashboard locating stud 10, it is characterized in that being equiped with in the valve seat 82 fan-shaped rotation flashboards 7, the throttle window of valve seat 8 is the fanlight of 165～180 degree (the best is 170 ± 2 degree), connect the cooperation aperture by flashboard 7 and realize flow control, and on valve seat 8, be equiped with the rotation positioning (seeing accompanying drawing 3 again) of flashboard locating stud 10 control flashboards 7, the manual rotation double-flashboard modulating valve of being formed.
For guaranteeing the precision height of this valve control flow rate, working stability through repetition test and comprehensive analysis, is preferably designed for the thickness of pressure-sensitive diaphragm 4 working portions in the automatic balancing valve group flexible sheet of 0.65～0.73 millimeter (the best is 0.7 millimeter).
