Description
Technical field
The utility model relates to a kind of modulating valve, especially relates to a kind of direct-operated regulator.
Background technique
Direct-operated regulator relies on pressure, the temperature of medium self in the valve of flowing through to work automatically as the driven by energy valve, does not need ABAP Adapter and secondary meter.Its advantage is to regulate automatically; With respect to electric control valve, its advantage is not need external impetus.Application practice proves, in closed-loop water system (like hot-water heating system, air conditioning water system), correctly uses this valve, can realize the assignment of traffic of system easily; Can realize the transient equiliblium of system; The debugging work of simplified system greatly; Can stablize the working state of pump etc.Existing direct-operated regulator generally is the single-iris structure; Like publication number is that the Chinese patent of CN2818965 discloses a kind of self-powering type pressure regulator valve, and as shown in Figure 1, it comprises valve body 1, valve gap 2, diaphragm 3, lower spring cup 4, Regulation spring 5, upper spring seat 6, adjusting screw 7, valve rod 8, spool 9, Returnning spring 10 and return spring holder 13; Valve body 1 center portion offers diaphragm chamber, valve rod via hole and spool bore successively; Valve body 1 both sides offer suction port and air outlet, and suction port is communicated with the spool mounting hole, and the air outlet is communicated with diaphragm chamber; Spool 9 is installed in the spool bore; Its upper-end surface and valve body 1 form sealing pair, an end of Returnning spring 10 and the lower ends of spool, and the other end links to each other with return spring holder 13; Diaphragm 3 covers diaphragm chamber that valve bodies 1 are offered and is connected with the diaphragm locular wall; Upper spring seat 6, lower spring cup 4 and on the Regulation spring 5 installed be positioned at diaphragm and contact with diaphragm with valve gap 2 formed cavitys and lower spring cup 4, adjusting screw 7 forms screw pairs with valve gap 2 and its underpart can contact upper spring seat 6, an end that it is characterized in that valve rod 8 is a screw rod; This screw part section and diaphragm 3 and lower spring cup 4 are integral through nut combinations, and the other end of valve rod 8 passes diaphragm chamber and inserts in the valve rod via hole of offering in valve body 1 center portion.This single-iris structure can cause that in use fluctuation is bigger, the problem that stability is bad.
Summary of the invention
The utility model mainly is that the fluctuation of solution existing in prior technology is bigger, and the technical problem that stability is bad provides a kind of fluctuation less, and the direct-operated regulator of extremely strong stability is arranged.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of direct-operated regulator, comprise valve body, spool, spring shield and bottom flange, and it is characterized in that the both sides up and down of described valve body are equipped with a flexible sheet; Valve body surrounds a pressure stabilizing cavity through this flexible sheet; The middle part of two flexible sheets is respectively equipped with punch holder and die holder up and down, and upper and lower clamping plate link to each other through connecting rod, and the upside of die holder is provided with spool; The exit orifice of the inlet passage of spool and valve body is suitable; Be provided with the upward pressure spring in the spring shield, upward pressure spring and upper clip offset, and are provided with the downforce spring in the bottom flange; Downforce spring and lower clamping piece offset, and described bottom flange is provided with one and is used for and the feedback hole that links to each other of outlet.Pressure medium (gas or liquid) gets into from exit orifice extruding spool from inlet passage, makes spool pass through die holder compression downforce spring, and exit orifice is opened, and medium gets into pressure stabilizing cavity, and flows out from outlet through pressure stabilizing cavity.In the process of move down at spool, exit orifice being opened; Following diaphragm middle part downwarping under the drive of die holder is because upper and lower clamping plate are continuous through connecting rod, so when die holder moves downward; Punch holder is also simultaneously to a motion, also downwarping in the middle part of the upper diaphragm.When outlet pressure was excessive, through the downside of feedback port extruding die holder, last die holder moved simultaneously, closes spool, reaches the regulating action to pressure medium.
As preferably, the described valve body area of the flexible sheet of both sides up and down is identical.Diaphragm area is the same up and down, and the power about pressure acts on the diaphragm guarantees the stable of valve element position too, and the pressure stability of output finally makes the valve regulated performance better.
As preferably, the inner chamber of described valve body is circular, and the exit orifice of described inlet passage is located at the circle centre position of valve body, and the exit orifice and the spool of described upward pressure spring, downforce spring, body cavity, inlet passage are all coaxial.This structure make spool and diaphragm motion, the distortion highly stable, can not squint, overturn.
As preferably, described spring shield is provided with the cylindricality endoporus, and cylindricality endoporus inwall is provided with internal thread, and internal thread is provided with adaptive with it regulating block, and the upper end of this regulating block and described upward pressure spring offsets.Rotate regulating block, make regulating block move up and down, can adjust the tightness of upward pressure spring, thereby realize the pressure of opening of valve is regulated.
As preferably, the length of described upward pressure spring be downforce spring length 2-4 doubly.When the length of upward pressure spring is longer, make that the linearity of this upward pressure spring is better.Help pressure controlled accurately, stable, and when the upward pressure spring being regulated through regulating block, to valve to open the adjusting that pressure carries out also more accurate.
The beneficial effect that brings of the present invention is, it is bigger to have solved the existing in prior technology fluctuation, and the technical problem that stability is bad has realized that a kind of fluctuation is less, and the direct-operated regulator of extremely strong stability is arranged.
