Description
Technical field
The present invention relates to a kind of valve, be meant the angie type that can reduce hydrodynamic pressure especially, directly act on reduction valve.
Background technique
At present; Various reduction valve kinds on market are a lot, but all to be a left side advance that the right side goes out or rightly advance the structure that a left side goes out for they, so on the total system, be the same; Be some local differences, the reduction valve of this structure also receives certain restriction in the practicality of some occasions in addition.
Summary of the invention
The present invention provides a kind of structure to be different from existing reduction valve, satisfies a kind of novel angie type of special occasions needs, directly acts on reduction valve.
Realize above-mentioned purpose, the present invention adopts following technological scheme: a kind of angie type, directly act on reduction valve, include valve body, case, relief pressure valve cartridge, adjusting screw rod, relief spring and diaphragm; It is characterized in that: the bottom of said valve body is provided with water intake, this water intake axially and valve body axial become vertical setting the, the valve pocket one side water outlet of said valve body; Said water intake and water outlet be provided with the position constitute reduction valve under advance the branch structure, the top of said valve body and the position corresponding with water intake are provided with passage, said diaphragm arrangement is on passage; Said case is located at the diaphragm top, and case cooperates formation one case cavity with valve seal, and water intake one side that is positioned at of said diaphragm is provided with relief pressure valve cartridge;, diaphragm and relief pressure valve cartridge axially are linked, and said adjusting screw rod one end passes diaphragm and is connected with relief pressure valve cartridge; The other end of adjusting screw rod passes from the last top of case and constitutes with it and is sealed and matched; Said relief spring is set on the adjusting screw rod end and conflicts on diaphragm, and the other end is conflicted on case, and said valve body is provided with pod apertures; The valve pocket conducting of this water conservancy diversion one end and valve body, the other end and the conducting of case cavity.
Through taking such scheme, the flow direction of our reduction valve employing medium is advanced branch under being, this spline structure is very simple, and the change of the kinetic energy of flow velocity and fluid, and effect of easing stress is fine; The power that produces between relief spring, spool and the valve seat in addition is in same rectilinear direction, so in design, the calculating of power is also fairly simple, can also prolong the life-span of valve.
Of the present inventionly further be set to: said water intake extends in the valve pocket of valve body and is provided with valve seat; Relief pressure valve cartridge cooperates the adjusting that constitutes the flow size with this valve seat; The periphery of said diaphragm and the passage of valve body periphery formation are sealed and matched; The outer end of case that is positioned at of said adjusting screw rod is provided with adjusting nut, and the elastic force size of relief spring can realize changing through the adjusting of adjusting nut to adjusting screw rod; The cross section of said spool becomes " king " shape, and the diameter of said water intake is less than the diameter of valve pocket.
Through the scheme of further setting, we are from minute structural feature of consideration product, what obtain on function and the cost making on the best effect basis; The maximum characteristics of this reduction valve are to change orifice size in addition, and the kinetic energy of flow velocity and fluid is changed, and cause the different pressure losses; Reach the decompression purpose; The cross section of spool becomes " king " shape, can play the control valve aperture like this, and the sealing effect of easing stress of valve can be improved; In further being provided with at last, the size adjustment of the elastic force of relief spring is very simple.
Below in conjunction with accompanying drawing the present invention is done further explain.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
As shown in Figure 1, a kind of angie type, directly act on reduction valve, include valve body 1, relief pressure valve cartridge 2, adjusting screw rod 3, relief spring 4 and diaphragm 5; In embodiments of the present invention, the bottom of said valve body 1 is provided with water intake 11, this water intake 11 axially and valve body 1 axial become vertical the setting; Valve pocket 12 1 sides of said valve body 1 are water outlet 13; The position that is provided with of said water intake 11 and water outlet 13 constitutes reduction valve for advancing the branch structure down, and our reduction valve adopts the flow direction of medium to advance branch under being, this spline structure is very simple; And the kinetic energy of flow velocity and fluid changes, and effect of easing stress is fine; The top of said valve body 1 and be provided with passage 14 with water intake 11 corresponding positions, said diaphragm 5 is arranged on the passage 14, and water intake 11 1 sides that are positioned at of diaphragm 5 are provided with relief pressure valve cartridge 2; Said adjusting screw rod 3 one ends pass diaphragm 5 and are connected with relief pressure valve cartridge 2;, diaphragm 5 axially is linked with relief pressure valve cartridge 2, and the other end of said adjusting screw rod 3 is provided with relief spring 4; One end of relief spring 4 is conflicted on diaphragm 5 through liner; The other end is conflicted on the case 15 of valve body 1, and the power that produces between relief spring of the present invention 4, spool 2 and the valve seat is in same rectilinear direction, so in design; The calculating of power is also fairly simple, can also prolong the life-span of valve.
In embodiments of the present invention, said water intake 11 is provided with valve seat 16 towards valve pocket 12 interior extensions of valve body 1, and relief pressure valve cartridge 2 cooperates the adjusting that constitutes the flow size with this valve seat 16; The passage 14 periphery formations of the periphery of said diaphragm 5 and valve body 1 are sealed and matched; Said case 15 lids are located at the top of the passage 14 of valve body 1, and constitute the case cavity 17 of formation that is sealed and matched with valve body 1, and diaphragm 5 places in the case 15 with relief spring 4; The upper end of adjusting screw rod 3 is passed the setting of case 15 upper ends and is constituted and is sealed and matched; Said valve body 1 is provided with pod apertures 18, valve pocket 12 conductings of these pod apertures 18 1 ends and valve body 1, the other end and 17 conductings of case cavity.The case 15 outer ends that are positioned at of said adjusting screw rod 3 are provided with adjusting nut 31; The elastic force size of relief spring 4 can realize through the adjusting of 31 pairs of adjusting screw rods 3 of adjusting nut changing, and the size adjustment of the elastic force of the relief spring 4 of this mode is very simple; The cross section of said spool 2 becomes " king " shape, and the sealing effect of this valve can be improved like this, and the diameter of said water intake 11 is less than the diameter of valve pocket 12; This reduction valve like this; Can also cause the different pressure losses through changing orifice size, reach effect of easing stress.
Concrete working principle: utilize the import pressure medium to open spool 2, spool 2 promotes diaphragm 5 and moves upward.When outlet pressure reaches when needing, medium flows to case cavity 17 from valve pocket 12 through pod apertures 18, and the hydraulic pressure in the case cavity 17 promote relief pressure valve cartridge downwards with relief spring 4 like this, and valve opening is reduced, and the assurance outlet pressure is constant.
