Description

A valve for regulating temperature}

The present invention relates to a temperature control valve, and more particularly, to a temperature control valve capable of opening and closing a flow path of a valve body by using a temperature difference of a fluid flowing inside a valve body with a simpler configuration.

The temperature control valve is a valve that controls the flow of fluid by sensing the temperature change of the fluid. It is necessary to control the heating by using hot water in general households or to control the flow of gas appropriately according to the temperature change in the industrial field , Or to cope with the temperature change of the cooling water of the automobile.

A typical example of such a temperature control valve is shown in Fig. As shown in the drawing, the conventional temperature control valve is configured such that one side of the space of the operation chamber 1a of the valve body 1 is partitioned by the diaphragm 7 to fill the wax 10, The disk 4 provided at the lower end of the slider 5 while the wax 10 is contracted or expanded when the valve body portion filled with the wax 10 is heated or cooled, Respectively.

However, since the conventional temperature control valve is provided with a wax as a power source for opening and closing the flow path of the valve body, the flow path opening and closing of the valve body is not limited to the temperature change of the fluid but the temperature change of the valve body itself . That is, the fluid is not directly sensed by operating the temperature change of the fluid flowing inside the valve body, but is operated by continuously transmitting the heat of the fluid that has exited through the discharge port 3a to the valve body. There is a problem in that it can not be applied when it is necessary to open and close the channel in real time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the technical features of the present invention, A detailed description thereof will be omitted.

1 is a schematic cross-sectional view of a temperature control valve according to the present invention. As shown in the drawings, a support 10 mounted on a valve body 1, an actuator 20 installed on a support 10, a shaft 30 and a spring 40, and a disk 50 . Hereinafter, each of these configurations will be described in detail.

The valve body 1 is a conventional means used for controlling the flow of fluid, in which a fluid inlet 2 is provided at one side and a fluid outlet 6 is provided at the other side. A working chamber 4 of a predetermined size is provided on the central portion of the valve body 1. The working chamber 4 communicates with the fluid inlet 2 and the fluid outlet 6, respectively.

The support body 10 is provided with a through hole 12 and a mount table 16 and is mounted in the operation chamber 4 of the valve body 1. [ The through hole 12 is provided on both sides of the support 10 as a passage through which the fluid moves. The holder (16) is provided radially on the lower central portion of the support (10) as a part for mounting the spring (40). As the cradle is formed radially, the fluid can pass freely through the cradle. Reference numeral 11 denotes a supporting end for supporting the upper end portion of the support body 10.

The actuating body 20 is a means for opening and closing the flow path of the valve body 1 and includes a guide end 22, a guide tube 24, a housing 26, an elastic film 28 and a wax 25 . The guide end 22 is provided at the upper end portion of the actuating member 20 and may be formed into a rod shape having a predetermined length. As a result, both end portions of the guide end 22 rise and fall vertically along the through-hole 12.

The guide tube 24 is a portion into which the shaft 30 is inserted. One end portion of the guide tube 24 extends through the central portion of the guide end 22, and the other end portion extends downward. As a result, the guide tube 24 is lifted vertically together with the guide end 22. The housing 26 is provided at the other end of the guide tube 24. The housing 26 is formed with an inner receiving space of a predetermined size, and the inner receiving space communicates with the other end of the guide tube 24.

The elastic membrane 28 divides the other end portion of the guide tube 24 and the upper end portion of the accommodating space in the housing 26, which are communicated with each other by an external force. Although the case where the elastic membrane 28 is formed in a plate shape is shown in the drawing, the present invention does not exclude the case where the elastic membrane 28 has a three-dimensional shape similar to the inside accommodation space of the housing 26. [

The wax 25 is filled in the housing space of the housing 26. The wax senses the temperature change of the fluid and expands and contracts. When the elastic membrane is formed into a three-dimensional shape, the wax is filled in the elastic membrane. The thickness of the housing 26 can be adjusted for proper temperature change detection of the wax.

The shaft 30 is inserted into the guide tube 24 as a pin having a predetermined length. The one end portion of the shaft 30 is supported by the central portion of the upper surface inside the support body 10 and the other end portion thereof is in contact with the upper surface of the elastic film 28. [ The shaft may be made of metal, in which case the elastic membrane may be damaged by the shaft. To this end, the present invention does not exclude the case where a synthetic resin pin is mediated between the other end portion of the shaft 30 and the elastic membrane 28.

The spring 40 surrounds the guide tube 24 as a means for providing a restoring force. One end of the spring 40 is in contact with the lower surface of the guide end 22, and the other end of the spring 40 is in contact with the cradle 16. The degree of restoring force of the spring is preferably determined in consideration of the degree of expansion of the wax.

The disk 50 is mounted on the lower end of the guide tube 24 and the upper end of the housing 26 as a means for opening and closing the flow path. As a result, the disk ascends and descends vertically together with the actuating member 20. [ It is preferable that the disc has a plate-like structure with a certain thickness.

A schematic operational configuration of the present invention having such a configuration will be described with reference to FIGS. 1 and 2, respectively.

First, when a fluid flows through the fluid inlet 2, the fluid presses the disk 50 and the lower portion of the housing 26 with a constant force, and a part of the heat of the fluid flows through the housing 26 into the wax 25 . By the heat transferred, the wax 25 pushes the elastic membrane 28 upward while expanding. When the temperature of the fluid is low and the heat transferred to the wax is not sufficient, the expansion force of the wax 25 is smaller than the elastic force of the spring 30, so that the flow path of the valve body maintains the closed state as shown in FIG.

2, the expansion force of the wax 25 is greater than the restoring force of the spring 30. As a result, as shown in FIG. 2, The upper side 29 is pushed up into the guide pipe 24. When the upper side 29 of the elastic membrane 28 is pushed up into the guide tube 24 because the shaft 30 has a predetermined length, the guide end 22 connected to the guide tube 24 is urged by the spring 40) while descending as shown in the drawing.

Since the guide end 22 and the guide tube 24 and the housing 26 are integrally connected and the disk 50 is mounted on the housing 26, Also falls. Thereby, the flow path of the valve body is opened, and the fluid moves through the holder 16 and the through hole 12, and then exits the valve body 1 through the fluid outlet port 6.

The valve opening of the valve body 1 continues until the temperature of the fluid exceeds a predetermined value and the expansion force of the wax 25 is greater than the restoring force of the spring 40. As the temperature of the fluid decreases and the heat transferred to the wax 25 decreases, the expansion force of the wax 25 becomes smaller than the restoring force of the spring 40, And returns to the state of Fig.

As described above, according to the present invention, the flow path of the valve body can be easily opened and closed through the simple structure of the support and the actuator, and the housing in which the wax is filled can be directly contacted with the fluid flowing in the valve body, And can immediately respond to the temperature change.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be apparent that the present invention can be practiced with added features.
