Abstract

The utility model relates to a temperature balance control valve for heat supply and hearting, which is a self-control valve which is arranged in a heating backwater pipeline and used for controlling and maintaining the temperature of each building and living room. A valve body is a tubular housing in which a control valve spool is arranged; an inwards convex annular valve seat 2 is arranged in a front valve body 1, and an adjustable telescoping valve 3 is arranged in the control valve spool; when the adjustable telescoping valve 3 reaches a definite temperature because of heating, the adjustable telescoping valve 3 is outwards extended and shrunk because of the action of an expander 10, and the space between the adjustable telescoping valve 3 and the valve seat 2 is closed; when the temperature descends, a return spring 6 makes the adjustable telescoping valve 3 return. In this way, the quantity of the backwater of a heater can be controlled, and the heat quantity entering a heat supply pipe is influence so as to achieve the requirements of controlling and maintaining the temperature of the living rooms.

Description

Temp balance controlling valve for supplying heat and heating

Heat supply heating temperature balance control valve is the water return pipeline that is used for heat supply heating, the control valve that each building and user's serviceability temperature are automatically adjusted.It is to realize its international Patent classificating number: F28F13/08 by the size that changes circling water flow rate.

In the reality, the adjustment control problem of the serviceability temperature of the heat supply heating of producing and living, have plenty of and undertaken by the size of heat supply caliber, most cases is that the heating worker carries out flow-dividing control by manually-operated gate to the shunting heating tube, manually-operated gate does not have automatic control function, and certain building and unit can not in time be regulated and control with hot temperature variation.Now, the more advanced automatically controlled automatic valve of a kind of technology is arranged, it has liberated artificial adjustment problem, can in time control automatically, but its problem is just to work when a certain specified temp, or close or Open valve, lack gradually preface control procedure of temperature range, the temperature control action is undesirable, and the reliability of Shi Yonging is relatively poor in addition, safeguard inconvenience, therefore fail to be widely adopted.

The purpose of the utility model development, provide a kind of being installed on the heating reclaim line, make the effect of the excessive heat supply function of its existing minimizing, energy saving, can keep the indoor temperature can be not low excessively again, can realize gradually preface control in the uniform temperature interval, use reliably, carry out the control valve of temperature balance regulation and control automatically.

The technical characteristics of this control valve is that it comprises valve body and two parts of spool.Valve body is divided into front valve shell 1 and rear valve body 9, the front and back valve body connects into the articulated pipe sandwich type element by attaching nut 11, be provided with screw thread at the right-hand member of the left end of front valve shell 1 and rear valve body 9 and be convenient on pipeline, install, receive the place, footpath at the inner chamber of front valve shell 1 and be provided with convex ring-type valve seat 2.Spool partly constitutes one by the hot swollen device 10 that rises of valve 3, valve lever 7 and interior dress paraffin expansion material makes the overhanging mechanism of valve, constitute one by return spring 6, spring front stall 4, spring back seat 8 and valve core frame 5 and make the valve return mechanism, valve 3 cooperates with valve seat 2 and works, and restriction circling water flow rate or closed valve seat are by backwater.Make gap smaller between it and the valve seat until sealing during valve 3 elongation.Valve 3 overhanging be to realize that by the swollen effect of rising of the hot swollen device 10 that rises that fills the wax expansion material its retraction is when temperature reduces by valve lever 7, the return by the compression of return spring 6.Valve 3, return spring 6, the swollen device that rises of heat etc. are positioned on the valve core frame 5 altogether, and valve core frame 5 inlay cards are between preceding shoulder 12 and back shoulder 13.

Advantage of the present utility model:

This control valve is positioned on the water return pipeline, and excessive heat supply, temperature of equilibrium and the energy-conserving action of minimizing arranged.When return water temperature reached 75 ℃, control valve was in closed condition, forced heat supplying pipeline to suspend heat supply, when backwater during 60 ℃ of left and right sides, the backwater amount can reduce to 1/2, and heat supply is restricted, by the time 40 ℃ the time, valve 3 basic standard-sized sheets, a large amount of backwater of return pipe, the amount that supplies of heat supply pipeline strengthens;

This control valve is simple in structure, directly connects by screw thread with water return pipeline, and installation and maintenance are convenient, and operational safety is good.

Use this control valve particularly suitable to central heat supply and boiler heat supplying user.It can prevent each building and each room, unit overheatedly can prevent coldly again, promptly can in the holding chamber a suitable temperature of equilibrium be arranged.

Embodiment:

This control valve can be selected different types for use according to the caliber specification that is used in concrete water return pipeline, and existing is example by the 1 inch water return pipeline that is used in the household heater sheet, and the narration embodiment is as follows:

The cylinder iron part processing of valve body part, front valve shell 1 and rear valve body 9, both are connected by attaching nut 11,140 millimeters of the back length overalls of joining.Valve cavity will be done the processing of several places, valve seat 2 will guarantee the footpath mouth of 25 millimeters of diameters, to be processed with the inner conical surface of 45 degree in a side of corresponding valve, inner chamber turning processing to front valve shell 1 particle size place makes internal diameter keep 50 millimeters, and reach 39 millimeters in processing length and locate to form a spacing shoulder, shoulder 12 promptly, to guarantee the installation of valve core frame 5, the small end of front valve shell (front end) car is shaped on the internal thread that joins with water return pipeline; The back shoulder 13 of an installing and locating valve core frame 5 of rear valve body 9 left ends processing, also car has screw thread in the right-hand member of rear valve body 9, makes it to join with the water return pipeline of the other end.

Spool part, valve 3 are mounted in the domed cap on the valve lever 7, and are provided with screw thread, can do the temperature adjustment, it stretch out or bounce back changing and valve base between the space, thereby changing the flow of backwater, reach the purpose of control heating temperature; The paraffin temperature sensing material is equipped with in swollen device 10 the insides of rising of heat, and the paraffin temperature sensing material was swollen when water temperature increased rises and to promote valve 3 close to valve seat 2, and return spring 6 is to make valve 3 return gradually when return water temperature reduces.This control valve is realized temperature adjusting between 40 ℃～75 ℃ of return water temperatures.

Claims

1, heat supply heating temperature balance control valve, comprise two parts of valve body and spool, it is characterized in that valve body is to be constituted tubular shell with rear valve body 9 and adopted movable joint nut 11 to be connected by front valve shell 1, the receipts that are positioned at front valve shell 1 at body cavity directly locate to be provided with convex ring-type valve seat 2, the overhanging mechanism of spool is made of the hot swollen device 10 that rises of extension valve 3, valve lever 7 and interior dress paraffin expansion material, the return mechanism of spool is by return spring 6, spring front stall 4, spring back seat 8 and valve core frame 5 constitute, and inlay card is installed between preceding shoulder 12 and back shoulder 13 by valve core frame 5 by spool mechanism.
