Abstract
The invention discloses a proportional valve with adjustable control flow. A valve body consists of an upper valve body and a lower valve body, wherein at least two flow limiting holes and external joint connection blind holes are formed in the lower valve body along the axial direction; a three-section through hole is formed in the upper valve body along the axial direction; a small-diameter section in the middle of the through hole is an eccentric hole section; a filter screen is mounted on the large-diameter section of the upper part of the through hole; a seal ring is embedded in the large-diameter-section hole bottom of the lower part of the through hole of the upper valve body; the small-diameter section of the upper part of the lower valve body is inserted into the large-diameter section of the lower part of the through hole of the upper valve body; an annular limit boss of an insertion part is clamped into an annular limit slot of the large-diameter section; the upper end surface of the lower valve body is clung to the bottom surface of the seal ring; the small-diameter section of the through hole of the upper valve body is communicated with one flow limiting hole. According to the proportional valve with adjustable control flow, the lower valve body and the upper valve body oppositely rotate, so that the small-diameter section of the through hole of the lower valve body is communicated with different flow limiting holes, and thus the control flow can be changed; the proportional valve has the function of adjusting flow.
Description
Technical field
The invention belongs to control valve field, specifically, particularly relate to a kind of Proportional valve of adjustable control flow.
Background technique
As described in Figure 1, traditional Proportional valve is monolithic construction, and be made up of valve body 1 and filter screen 2, wherein valve body 1 center hole is the 3 stops shoulder hole of being small at both ends and big in the middle, wherein central diameter section is restricted section, and the large footpath section of upper and lower part is external connector linkage section, and the large footpath section on top is embedded with one piece of described filter screen 2.
The different just corresponding different control flow in restricted section aperture due to Proportional valve, and the restricted section aperture of existing Proportional valve is fixed, so just cause the flow control of existing Proportional valve non-adjustable, thus it is for subsequent use to need to buy multiple different Proportional valve, and then adds user cost.
Summary of the invention
Technical problem to be solved by this invention is the Proportional valve providing a kind of flow adjustable.
Technological scheme of the present invention is as follows: a kind of Proportional valve of adjustable control flow, comprise valve body (1) and filter screen (2), it is characterized in that: described valve body (1) is made up of upper valve body (1a) and lower valve body (1b), wherein descend valve body (1b) has vertically metering hole (1b ') and be connected blind hole (1b ") with external connector, wherein: described metering hole (1b ') number is at least 2, these metering holes are eccentric opening, and be distributed in circumferentially same, and upper valve body (1a) upper-end surface is run through in the upper end of these metering holes (1b '), its lower end is connected with described external connector at the bottom of the hole on blind hole (1b ' ') top and is communicated with, lower valve body (1b) lower end surface is run through in the lower end that this external connector connects blind hole, described lower valve body (1b) is big end down two-part hierarchic structure, and the path pars infrasegmentalis of this lower valve body has an annular stop boss (1b " '),
Described upper valve body (1a) has vertically the through hole of a 3 stops, the large footpath section of upper and lower part is center hole section, the path section at middle part is eccentric opening section, and the large footpath section on top is equipped with one piece of described filter screen (2), the outward edge of this filter screen embeds in the annular mounting groove bottom the section of large footpath; A seal ring (3) is embedded with at the bottom of the large footpath sector hole of described upper valve body (1a) through hole bottom, sealing circle is positioned at outside the path section of upper valve body (1a) through hole, and the underpart of this large footpath section has an annular spacing groove;
The path section on described lower valve body (1b) top is inserted in the large footpath section of upper valve body (1a) through hole bottom, the annular stop boss of this insertion part (1b " ') snaps in the annular spacing groove of this large footpath section; and lower valve body (1b) upper-end surface and described seal ring (3) bottom surface are close to, and the path section of upper valve body (1a) through hole can be communicated with wherein metering hole described in any one (1b ') simultaneously in metering hole described in any one (1b ') be communicated with.
During use, lower valve body (1b) and upper valve body (1a) can be relatively rotated, thus allow the path section of lower valve body (1b) through hole and different metering hole (1b ') be communicated with, so just can change and control flow, thus make this Proportional valve have the function of adjust flux, and then overcome conventional construction because can not regulable control flow and need the defect of plurality of specifications Proportional valve for subsequent use, and the present invention just solves large problem by little change, there is good practicability.And, because lower valve body (1b) and upper valve body (1a) are connected by annular stop boss (1b " '); axial displacement can not occur when these two valve bodies relatively rotate; so just can ensure sealing well; thus very effectively avoid the path section of lower valve body (1b) through hole to be communicated with two metering holes (1b ') simultaneously, so just can ensure normal work of the present invention.
As optimizing design scheme, the number of described metering hole (1b ') is 4, and its number is moderate.
For the ease of connecting lower valve body (1b) and upper valve body (1a), the end face of described annular stop boss (1b " ') is inclined-plane, and this inclined-plane is outer low and inner high, and the gradient on inclined-plane is 15 °-30 °.
As preferably, the aperture of the non-insertion portion of described lower valve body (1b) is equal with the aperture of upper valve body (1a).
Beneficial effect: the present invention can relatively rotate lower valve body and upper valve body, thus allow the path section of lower valve hole be communicated with from different metering hole, so just can change and control flow, thus make this Proportional valve have the function of adjust flux, and then overcome conventional construction because can not regulable control flow and need the defect of plurality of specifications Proportional valve for subsequent use, and can not axial displacement be there is when relatively rotating in two valve bodies, so just can ensure sealing well, thus very effectively avoid the path section of lower valve hole to be communicated with two metering holes (1b ') simultaneously, so just can ensure normal work of the present invention.
