Abstract

The utility model relates to a double adjusting temp.-controlled valve, comprising a valve seat 3, a pressing plate 10, a valve cap 1, a small shaft 4, a bimetallic strip 5, a sealing ring 11, and a sealing ring 12. The valve seat 3 is provided with two valve ports A9 and B7 which are arranged side by side, and a port cover 6 which can seal the valve ports. The small shaft 4 is fixed in the valve seat 3 through the pressing plate 10 and the valve cap 1. One end of the bimetallic strip 5 is fixed on the small shaft 4, and the other end of the bimetallic strip 5 is fixedly connected with the port cover 6. The sealing ring 11 is arranged between the pressing plate 10 and the valve seat 3. The sealing ring 12 is arranged between a shoulder 13 of the small shaft 13 and the pressing plate 10. The small shaft 4 is provided with a turn button 2. The utility model has the advantages of favorable regulation, reliability, high sensitivity and long service life.

Description

Temp controlled dual-regulation valve

The utility model relates to heating engineering device, and especially a kind of northern area heating Engineering Control radiator heat water flow that not only can be used for to keep suitable room temperature, also can be used for the temp controlled dual-regulation valve of southern area Refrigeration and Air-conditioning Engineering simultaneously.

It is the development trend of building energy conservation that heat supply heating charges by heat, is basic measures of various countries' energy-conserving and environment-protective.Heating is carried out and is pressed the heat charge, could realize reasonable heat supply under the prerequisite of setting up a comfortable thermal environment, and country is energy-conservation, and the user saves money.Implementation heating is that temperature control valve (TCV) is installed on radiator by an important prerequisite of heat charge, makes user's aperture of regulating valve voluntarily, and control flow rate is regulated room temperature.The more important thing is that when indoor acquisition solar radiation, indoor thermal source etc. are free when hot, room temperature is raise, the temperature control valve (TCV) on the radiator should be able to reduce the water yield of the radiator of flowing through automatically, keeps reasonable room temperature.

Heat supply heating is pressed the existing mature experience of heat charging abroad, but Radiator Thermostatic Controller is according to the two-pipe system design abroad, it can not be applied to the single tube forward flow system that China's convention is continued to use simply.The single-main distribution employing adds the method for crossing over pipe transforms, and just can install radiator thermostat valve additional, realizes regulating the room temperature separately.

The purpose of this utility model is to provide a kind of and not only can be used for northern area heating engineering, and can be used for the temp controlled dual-regulation valve of southern area Refrigeration and Air-conditioning Engineering by the heat charge for realizing.

The purpose of this utility model is achieved in that temp controlled dual-regulation valve described in the utility model comprises valve seat, pressing plate, valve gap, little axle, bimetallic strip and seal ring.Except that having liquid chunnel, also be provided with two valve openings side by side on the valve seat, and be provided with a port lid that can seal valve opening.Little axle is fixed in the valve seat by pressing plate and valve gap.One end of bimetallic strip is fixed on the little axle, and the other end and port lid are connected.Bimetallic strip is a memory alloy.Pressing plate and valve base chamber are provided with O-ring seal.Be shaped on a convex shoulder on the little axle, also be provided with O-ring seal between convex shoulder and the pressing plate.

When temp controlled dual-regulation valve was used for heating system, along with the rising of fluid temperature (F.T.), bimetallic strip was out of shape to a side, and port lid is shifted to valve opening A from the central position, and when reaching predefined temperature, port lid will cover valve opening A fully; When temp controlled dual-regulation valve was used for air-conditioning refrigeration system, along with the reduction of fluid temperature (F.T.), bimetallic strip was out of shape to opposite side, and port lid is shifted to valve opening B from the central position, and when reaching predefined temperature, dome will cover valve opening B fully.Be capped entirely from the valve opening that is open to entirely of valve opening, just realized flow control, the purpose of regulating temperature, saving the energy.

The utility model has the advantages that to have good modulability, reliability, and also highly sensitive, the life-span is long, and it not only can be used for the heating engineering, also can be used for Refrigeration and Air-conditioning Engineering.

Fig. 1 is the plan view of the utility model temp controlled dual-regulation valve;

Fig. 2 is the sectional view of Fig. 1;

Fig. 3 is the working principle schematic representation of the utility model temp controlled dual-regulation valve.

The utility model is described in further detail below in conjunction with embodiment shown in the drawings:

As shown in Figure 1 and Figure 2, temp controlled dual-regulation valve described in the utility model comprises valve seat 3, pressing plate 10, valve gap 1, little axle 4, bimetallic strip 5 and seal ring 11, seal ring 12.Except that having liquid chunnel, also be provided with two valve opening A9 and valve opening B7 side by side on the valve seat 3, and be provided with a port lid 6 that can seal valve opening A9 or valve opening B7.Little axle 4 is fixed in the valve seat 3 by pressing plate 10 and valve gap 1.One end of bimetallic strip 5 is fixed on the little axle 4, and the other end and port lid 6 are connected.Bimetallic strip 5 is a memory alloy.3 of pressing plate 10 and valve seats are provided with O-ring seal 11.Be shaped on a convex shoulder 13 on the little axle 4, be provided with O-ring seal 12 between convex shoulder 13 and the pressing plate 10.On the little axle 4 knob 2 can be set, turning knob 2 just can drive little axle 4 and regulate the tension force of bimetallic strip 5, thereby changes predefined temperature.For ease of operation, can be provided with the nameplate 8 of scale on the valve gap 1.
