Abstract

The utility model relates to a heating pipe three way temp. control valve which is used for heat supply heating system. In the existing single pipe system, the both ends of each radiator are connected in parallel with crossing pipes and arranged on the utility model, which can conveniently control the flow quantity of the hot water which flows across the radiator. The heating pipe three way temp. control valve is composed of a thermostat, a valve rod 8, an upper valve clack 5 and a valve body, wherein, the inside of the valve body is provided with an inner cavity 12 and an upper outer cavity 14. The utility model is characterized in that the lower part of the inner cavity 12 is provided with a lower water outlet 9; a lower valve clack 10 which is fixed on the lower end of the valve rod 8 is matched with the lower water outlet 9; when the lower valve clack is moved up and down, the flow quantity of the lower water outlet 9 can be adjusted.

Description

Heating pipe three way temp. controlling valve

The utility model relates to a kind of heat-operated valve that is used for hot water system.

In the prior art, hot water system mainly divides single-main distribution and two-pipe system.Single-main distribution is with a water pipe some radiator tandems to be formed, the heat that the radiator of this single-main distribution is dispersed is difficult to control respectively, for example when the room temperature at some radiators place is too high, need reduce hot water flow, but the hot water flow of making the radiator that can make other like this also and then reduces, so single-main distribution wastes energy.

In order to address the above problem, can a leap in parallel manage at each radiator two ends, the purpose of this utility model just provides the hot water flow in a kind of can regulate radiator and the leap pipe, thus the control radiator is dispersed the HVAC threeway thermostat valve of heat.

The purpose of this utility model can realize by following technical proposal:

The utility model is made up of temp controller, valve rod, last flap and valve body; The action do-part of temp controller withstands on the upper end portion of valve rod; Inner chamber and last exocoel are arranged in the valve body, between inner chamber and the last exocoel upper water-out mouth is arranged, make inner chamber and last exocoel communicate, inner chamber also communicates with the water intake of valve body; Last flap matches with the upper water-out mouth, and is fixed on the interior valve rod of exocoel; The below of inner chamber also has a lower outlet, and described lower outlet and upper water-out mouth are on the same shaft axis; The underpart of valve rod is fixed with lower Disc, and described lower Disc is arranged in the following exocoel of lower outlet below.Last exocoel is connected with the water intake of radiator, and following exocoel is connected with the water intake of crossing over pipe.When room temperature is higher than required setting, the action do-part compression valve rod of temp controller makes flap and lower Disc simultaneously to bottom offset, hot water flow through the upper water-out mouth reduces, hot water flow through lower outlet increases, the hot water flow of radiator of consequently flowing through reduces, and indoor temperature just reduces; When room temperature is lower than required setting, moving valve rod on the action do-part of temp controller makes flap and lower Disc simultaneously to top offset, hot water flow through the upper water-out mouth increases, hot water flow through lower outlet reduces, the hot water flow of radiator of consequently flowing through increases, and indoor temperature just raises.

The utility model compared with prior art has following advantage:

After in single-main distribution, installing and using the utility model, can regulate the hot water flow of some radiators of flowing through easily, and not influence the hot water flow of same ducted other radiator, save the energy widely.Last flap and lower Disc do not produce direct friction with valve body when moving up and down, so the moving resistance of valve rod is very little, can directly control valve rod with temp controller.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is a structure sectional view of the present utility model, wherein:

［ 1 ］, gland nut; ［ 2 ］, seal ring; ［ 3 ］, manual tune cap; ［ 4 ］, reciprocal spring; ［ 5 ］, go up flap; ［ 6 ］, rubber band; ［ 7 ］, water intake; ［ 8 ］, valve rod; ［ 9 ］, lower outlet; ［ 10 ］, lower Disc; ［ 11 ］, upper water-out mouth; ［ 12 ］, inner chamber; ［ 13 ］, following exocoel; ［ 14 ］, go up exocoel.

As shown in drawings, the utility model is made up of temp controller, valve rod 8, last flap 5 and valve body.That temp controller can adopt automatic type or manually operated type, represented in the accompanying drawing is the manually operated type temp controller, mainly by manual tune cap 3, seal ring 2, gland nut 1, back and forth spring 4 is formed; Withstand on the upper end portion of valve rod as the manual tune cap 3 of the action do-part of temp controller; Inner chamber 12 and last exocoel 14 are arranged in the valve body, between inner chamber 12 and the last exocoel 14 upper water-out mouth 11 is arranged, make inner chamber 12 and last exocoel 14 communicate, inner chamber 12 also communicates with the water intake 7 of valve body; The bottom surface of last flap 5 is fixed with the rubber band 6 of ring-type, and all greater than the diameter of upper water-out mouth 11, when last flap 5 moved down, the rubber band 6 on the last flap 5 can cover upper water-out mouth 11 to the outer diameter of the diameter of last flap 5 and rubber band 6; The below of inner chamber 12 also has a lower outlet 9, and described lower outlet 9 is on the same shaft axis with upper water-out mouth 11; The underpart of valve rod 8 is fixed with lower Disc 10, and described lower Disc 10 is arranged in the following exocoel 13 of lower outlet 9 belows.The diameter of lower Disc 10 is slightly less than the diameter of lower outlet 9, and when mobile, lower Disc 10 can enter lower outlet 9 by following exocoel 13 on lower Disc 10.
