Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to dynamic balancing electric two-way valve, and the fluid be mainly used in heating system, air-conditioning system controls.
Background technique
Dynamic balancing electric two-way valve is applied within air-conditioning systems mostly, can not by pipe network pressure surge and make changes in flow rate, constant flow, being applied in fan coil system can temperature constant in holding chamber, not only improve the comfort level of user greatly, and serve good energy-conserving action.
Although existing dynamic balancing electric two-way valve can realize flow equilibrium fundamental function, but its structural design adopting flow equilibrium type more, flow equilibrium type valve is primarily of the Stainless Steel Valve courage of window and counterbalance spring composition, when valve inlet pressure increases, Stainless Steel Valve courage and spring are compressed, and discharge area reduces, but because inlet pressure increases, velocity of medium is accelerated, thus reaches flow equilibrium, and vice versa.But dynamic balancing electric two-way valve is arranged in room furred ceiling more, valve Stainless Steel Valve courage when system pressure fluctuates of flow equilibrium structure can produce the noise of creak creak, affects Consumer's Experience.In addition, the peak rate of flow of the valve of flow equilibrium type is fixedly installed before dispatching from the factory, and cannot regulate peak rate of flow at the scene during application, brings great inconvenience for design, type selecting and installation.Easily there is water hammer at indivedual scene in this valve simultaneously, causes pipeline current resonance.
Summary of the invention
In order to overcome the defect of electrodynamic balance Twoway valves, the utility model provides dynamic balancing electric two-way valve, to make up above-described technical deficiency.
The scheme that the utility model technical solution problem adopts is:
In upper valve body inside, regulation valve core is housed, regulation valve core is equipped with valve rod, valve rod is contained in adjustment top cover, in adjustment top cover outer cover, valve gap is housed, dial is provided with in valve cover upper planar surface, in the bottom of regulation valve core, the first spring is housed, in the bottom of upper valve body, secondary diaphragm clamping plate are housed, between secondary diaphragm clamping plate and primary diaphragm clamping plate, diaphragm is housed, pressure guide hole is provided with in upper valve body bottom, in lower valve body lower portion, balance valve seat is housed, balance valve seat upper space is equipped with valve core housing, second spring is housed inside valve core housing, in valve core housing internal sleeve, self-balancing valve core is housed, O shape is housed between self-balancing valve core and valve core housing enclose.
Good effect, the utility model valve volume is little, lightweight.Valve adopts upper and lower valve design, bellows middle-containing structure, reduces the volume of valve difficulty of processing and valve, is conducive to in-site installation.There is peak flow values regulatory function, facilitate the on-the-spot Flow-rate adjustment of user.With dial on valve top cover, realize the control of various flows value by adjusting different scale.Y type runner design, reduces valve resistance, and improves the control accuracy of valve.Be suitable for using as electrodynamic balance Twoway valves.
Accompanying drawing explanation

In figure, 1. upper valve body, 2. descends valve body, 3. valve rod, 4. regulation valve core, 5. adjusts top cover, 6. dial, 7. valve gap, 8. the first spring, 9. secondary diaphragm clamping plate, 10. diaphragm, 11. primary diaphragm clamping plate, 12.O shape is enclosed, 13. second springs, 14. valve core housings, 15. electronic valve seats, 16. balance valve seats, 17. pressure guide holes, 18. self-balancing valve cores.
Embodiment
As shown in Figure 1, in upper valve body 1 inside, regulation valve core 4 is housed, regulation valve core is equipped with valve rod 3, valve rod is contained in adjustment top cover 5, in adjustment top cover outer cover, valve gap 7 is housed, dial 6 is provided with in valve cover upper planar surface, first spring 8 is housed in the bottom of regulation valve core, in the bottom of upper valve body, secondary diaphragm clamping plate 9 are housed, diaphragm 10 is housed between secondary diaphragm clamping plate and primary diaphragm clamping plate 11, pressure guide hole 17 is provided with in upper valve body bottom, in lower valve body lower portion, balance valve seat 16 is housed, balance valve seat upper space is equipped with valve core housing 14, second spring 13 is housed inside valve core housing, in valve core housing internal sleeve, self-balancing valve core 18 is housed, O shape is housed between self-balancing valve core and valve core housing and encloses 12.
The utility model assembling is formed:
Wherein upper half part comprises upper valve body and bonnet assemblies.
Bonnet assemblies is assemblied on upper valve body by valve gap, and regulation valve core is connected with valve rod through valve gap, adjustment top cover, and consists of the first spring reset.
Adjusted the position of regulation valve core by the position controlling valve rod, adjustment top cover and valve gap regulate the range of regulation valve core by screw thread, thus realize the adjustment of valve peak rate of flow.Can regulate the peak rate of flow of valve by rotating adjustment top cover like this, and valve gap is equipped with dial, there is corresponding scale display.
Middle part be bellows, successively by primary diaphragm clamping plate, diaphragm and secondary diaphragm plywood sleeve on self-balancing valve core, compressed by roll extrusion mode.The project organization adopting bellows mid-is compact, can reduce valve volume and weight, be easy to in-site installation.
Lower half portion is screwed in lower valve body by the valve core housing that O shape circle is housed and assembles.
Finally, by the second spring and bellows mid-, then by fastening for the socket head screw that upper valve body is opposed with lower valve body corner, now, bellows is placed in the middle part of upper and lower valve body.This assembling mode is convenient to the repair demolition of valve, and socket head screw strength is large, can clamp diaphragm, prevent valve leakage out of steam system.
There is electronic valve seat in upper valve body, when valve rod is pressed onto bottom, drives regulation valve core to bottom, with electronic valve seat close contact, jointly realize Flow-rate adjustment and the closing function of valve with regulation valve core.
Be provided with balance valve seat in lower valve body, jointly play flow equilibrium effect with self-balancing valve core.Because self-powering type spool is placed in the middle part of valve, so its spool must adopt hollow design, carry out aperture adjustment by the edge of stainless steel cylinder and balance valve seat, thus realize the stable of pressure balance and flow.
As Fig. 2, valve adopts the structural design of low in and high out, and under valve, valve body is water inlet, and upper valve body is water outlet, and medium first flows through self-balancing valve core, then flows through regulation valve core, finally flowed out by upper valve body water outlet after being entered by lower valve body water inlet.Water inlet pressure is P1, valve central point pressure is P2, water outlet pressure is P3, owing to being provided with pressure guide hole in valve body, water outlet pressure imports diaphragm lower end by pressure guide hole, now the upper and lower pressure at two ends of diaphragm is valve central point pressure P 2 and valve export pressure P 3, along with water inlet pressure P 1 increases, P2, P3 two ends pressure reduction increases gradually, namely diaphragm upper and lower two ends pressure reduction is different, thus diaphragm and the motion of self-balancing valve core, again by the cooperation of the second spring, until when diaphragm upper and lower two ends pressure reduction is identical, diaphragm and the stop motion of self-balancing valve core, thus play the effect of pressure balance and stability of flow, otherwise still.
