Abstract
The utility model discloses a self-regulation type throttling valve, and relates to the technical field of valves. A valve deck is arranged above a valve body, a regulating handle is arranged above the valve deck, and a valve element sleeve is arranged in the middle of the valve body. A regulating rod is arranged above the valve element sleeve, guide blocks are arranged on the two sides of the regulating rod, and the outer side of each guide block is connected with a second O-shaped ring in a sleeved mode. A valve element shaft is arranged inside the valve element sleeve. The outer side of the position above the valve element shaft is connected with a first O-shaped ring in a sleeved mode, a channel is formed in the upper portion of the valve element sleeve, and the position below the valve element sleeve is fixedly connected with an outer ring through a screw. A valve seat is arranged below the valve body, a spring is arranged in the middle above the valve seat, and a through hole is formed in the outer ring and is communicated with an oil inlet and an oil outlet. By means of the self-regulation type throttling valve, the flowing area of liquid flow can be regulated according to pressure variation, so that the purposes of stabilizing the pressure of the outlet and regulating the flow of the outlet are achieved. The self-regulation type throttling valve is simple in structure, convenient to assemble and maintain, good in manufacturability and convenient to manufacture.
Description
Technical field
The utility model relates to valve technology field, be specifically related to a kind of automatic adjustable throttle valve.
Background technique
Common throttle valve is flow control element conventional in hydraulic system, and it is by changing throttling cross section or chock length to control the valve of fluid flow.Because the flow of throttle valve not only depends on the size of choke area, also relevant with the pressure reduction before and after restriction, the rigidity of valve is little, and application area is narrow, is only applicable to the less and less demanding occasion of speed stability of executive component load variations.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to be to provide automatically a kind of
Regulating type throttle valve.
To achieve these goals, the utility model is to realize by the following technical solutions: it comprises regulating handle 1, valve gap 2, valve core housing 3, valve body 4, outer ring 5, valve seat 6, spring 7, screw 8, poppet shaft 9, the one O shape circle 10, the 2nd O shape circle 11, guide pad 12, adjustable lever 13, filler opening a, oil outlet b, through hole c and passage e, the top of valve body 4 is provided with valve gap 2, the top of valve gap 2 is provided with regulating handle 1, the middle part of valve body 4 is provided with valve core housing 3, the top of valve core housing 3 is provided with adjustable lever 13, the both sides of adjustable lever 13 are provided with guide pad 12, guide pad 12 outsides are socketed with the 2nd O shape circle 11, the inside of valve core housing 3 is provided with poppet shaft 9, the upper outer of poppet shaft 9 is socketed with an O shape circle 10, the top of valve core housing 3 is provided with passage e, the below of valve core housing 3 is fixedly connected with outer ring 5 by screw 8, and the below of valve body 4 is provided with valve seat 6, and the upper center of valve seat 6 is provided with spring 7, on outer ring 5, be provided with through hole c, and through hole c is communicated with filler opening a and oil outlet b.
The beneficial effects of the utility model: it can be according to the variation of pressure, the area of passage of regulator solution stream, thereby reach stabilization of export pressure, regulate the object of rate of discharge, can be used for the Metering Flow Control Circuits with metering pump, relief valve composition, and can be used for pressure to working medium and the stability of flow has certain requirements in hydraulic system, applied range, and its is simple in structure, and I& M is convenient, good manufacturability, easily manufactured.
Brief description of the drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model poppet shaft;
Fig. 3 be in the utility model valve core housing partly cut open structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1-3, this embodiment is by the following technical solutions: it comprises regulating handle 1, valve gap 2, valve core housing 3, valve body 4, outer ring 5, valve seat 6, spring 7, screw 8, poppet shaft 9, the one O shape circle 10, the 2nd O shape circle 11, guide pad 12, adjustable lever 13, filler opening a, oil outlet b, through hole c and passage e, the top of valve body 4 is provided with valve gap 2, the top of valve gap 2 is provided with regulating handle 1, the middle part of valve body 4 is provided with valve core housing 3, the top of valve core housing 3 is provided with adjustable lever 13, the both sides of adjustable lever 13 are provided with guide pad 12, guide pad 12 outsides are socketed with the 2nd O shape circle 11, the inside of valve core housing 3 is provided with poppet shaft 9, the upper outer of poppet shaft 9 is socketed with an O shape circle 10, the top of valve core housing 3 is provided with passage e, the below of valve core housing 3 is fixedly connected with outer ring 5 by screw 8, the below of valve body 4 is provided with valve seat 6, the upper center of valve seat 6 is provided with spring 7, on outer ring 5, be provided with through hole c, and through hole c is communicated with filler opening a and oil outlet b.
This embodiment use time according to the match condition of the size of flow stream pressure and spring 7, outer ring 5 moves up and down with poppet shaft 9, if it is larger to export the pressure of oily b, make the hydraulic coupling on poppet shaft 9 tops be greater than spring force, poppet shaft 9 drives outer ring 5 to move down, reduce opening amount, thereby change flow section area, regulate the inflow-rate of water turbine of fluid, reach the object of the flow that automatic adjusting throttle valve passes through, if the pressure of outlet hydraulic fluid port b is little, the active force on poppet shaft 9 tops is less than spring force, outer ring 5 drives in poppet shaft 9 and moves under the effect of spring force, withstand valve core housing 3, opening amount is by regulating handle control, ensure that flow section area is constant, make valve possess the function of normal throttle valve.
