Abstract
An automatic flow balancer is composed of casing, piston, spring and ball valve assembly. It features that the casing has a circular outlet hole near the valve seat of the ball valve, the curved end of the piston with spring is opposite to the outlet hole of the casing, and the ball valve is installed at the outlet of the casing. The device can change the flow area along with the change of the external pressure, thereby enabling a user to have constant flow and keeping the system balance. The product has simple and compact structure, good adjusting performance, reliable work and unlimited installation position, and can effectively eliminate the hydraulic imbalance phenomenon commonly existing in heating and air conditioning systems.
Description
The utility model relates to a kind of automaton that is used for heating or air-conditioning system.
At present, ubiquity the hydraulic misadjustment problem in China's urban heating, the air-conditioning system, makes that each user's consumption of heating, air-conditioning is unbalanced, influences each user's demand, and has wasted the energy.
The purpose of this utility model provides a kind of automatic flow balancer, and this kind balancer can solve hydraulic misadjustment problem in heating, the air-conditioning system, makes that each user's the water yield controls to design discharge in the whole system, the autobalance of hydraulic regime in the maintenance system.
The utility model is made up of housing 1, piston 2, spring 3, back-up ring 4 and ball valve 5, and wherein ball valve 5 comprises guard shield 6, valve rod place seal washer 7, the sealing ring 9 between spherical valve core and the valve seat 8.It is characterized in that adjacent with ball valve 5 valve seats on housing 1 the round exit hole being arranged, piston 2 places housing 1 inner chamber, one end of piston 2 is flat anchor rings, there is perforate piston 2 inner core sides, and piston 2 other ends are the curved surface termination, and its termination is relative with the outlet opening of housing 1, spring 3 is enclosed within on the inner core of piston 2, back-up ring 4 connects at housing 1 entrance point, and joins with piston 2, and ball valve 5 is contained in the port of export of housing 1.
Operation principle of the present utility model is as follows:
When ball valve 5 under certain aperture, ambient pressure one regularly, water enters balancer with a flow of setting, differential pressure active force and spring 3 counter-force balances between this moment piston 2 flat choma face ends and housing 1 outlet opening, piston 2 is equilibrated on a certain position, when system pressure increases, the flow of balancer of flowing through has increase tendency, but because differential pressure increases, compression spring 3 reduces the flow area between piston 2 terminations and the outlet opening, with regard to having offset the factor that flow is increased owing to increased pressure, make flow still keep the flow that sets like this.When otherwise system pressure reduced, differential pressure reduced, the spring elongation, and flow area increases, and has offset owing to pressure reduces the factor that flow is reduced.Like this, no matter how intrasystem pressure fluctuates, and this balancer can both automatically keep user's regime flow.
The utility model is compared with prior art, and is simple and compact for structure, and adjusting function is good, reliable operation, and the installation site is unrestricted.Thereby can eliminate ubiquitous hydraulic misadjustment phenomenon in heating, the air-conditioning system, the quality of improving supply, energy savings effectively.
Description of drawings:
Figure is the utility model structural representation.
Embodiment of the present utility model:
The automatic flow balancer is installed in same housing 1 by back-up ring 4, piston 2, spring 3 and ball valve 5 and forms.Housing 1 inner chamber matches with piston 2, one end of piston 2 is one flat mouthful of ring surface, its inner core sidewall has four holes of symmetry, the tapered termination of other end central authorities of piston 2, this termination is relative with the outlet opening of housing 1, spring 3 is enclosed within on the inner core of piston 2, back-up ring 4 is equipped with ball valve 5 at the port of export that housing entrance point and piston are connected on housing 1 mutually, one side valve seat and housing cast solid, opposite side valve seat 8 and housing are with being threaded, sealing ring 9 is positioned on the valve seat and cooperates with spherical valve core, and there is seal washer 7 housing and valve rod cooperation place, and there is helmet 6 at the overhanging place of ball valve valve rod.Housing 1 usefulness nodular cast iron is made an integral body, and common charcoal steel is made back-up ring 4, and piston 2 usefulness stainless steels are cast, and spring 3 usefulness rustproof spring steels are made, and the ball valve core of ball valve, valve rod are made with stainless steel, and all seals of ball valve are made stand-by with polytetrafluoroethylene.
In the spring 3, piston 2, the back-up ring 4 that process pack into housing 1 successively from arrival end, the valve seat 8 of ball valve, spool, valve rod and helmet 6, seal washer 7, sealing ring 9 are installed in housing 1 port of export one side, form the automatic flow balancer.
