Description of the Invention: [Technical Field] The present invention relates to a fluid controller for opening or blocking a fluid passage provided in a body to control fluid flowing in the same passage, particularly with respect to needs External heating or cooling fluid controller. [Prior Art] A fluid controller that uses a heat medium for heating or cooling has been known from the prior art, for example, as disclosed in Patent Document 1. [Problem to be Solved by the Invention] Heating using warm water as a heat medium is not necessary to use electric power, and high temperature can be utilized as compared with heating using a heater. The point of drainage or the like is advantageous. However, when compared with a heater, there is a problem that it is difficult to increase the temperature of the warm water, and thus an improvement in heating efficiency is desired. SUMMARY OF THE INVENTION An object of the present invention is to provide a fluid controller which can improve heating efficiency in the case of using warm water. [Means for Solving the Problem] The fluid controller according to the present invention includes: a body having a block portion in which a fluid passage is provided, a tubular portion extending from a top surface thereof, and an actuator for opening and closing a fluid passage in the body, and characterized in that The upper cover is covered on the top surface of the block portion of the body, and an upper heat medium space for holding the heat medium is formed between the top surface of the tubular portion and the outer peripheral surface of the tubular portion of the body; the bottom cover of the block portion of the body is covered with a lower cover, and the present cover is used with 201027017 A lower heat medium space for holding a heat medium is formed between the bottom surfaces of the block portions, and at least one piece connecting the upper heat medium space and the lower heat medium space is formed inside the block portion of the body so as to avoid the fluid passage. Thermal media path. In the present invention, the front end side of the tubular portion of the main body is the upper end, and the base end side (the block portion side) is the lower side. However, the "upper and lower" is used for convenience, and the vertical direction is also used. Towards the level, the situation is reversed upside down and used.流体 The fluid controller has a general opening and closing valve as well as a control valve. The configuration of the fluid controller is not limited in any case, and the configuration of the fluid controller can be made to have various configurations and various functions. In other words, with respect to the fluid controller including the main body having the fluid passage and the actuator for opening and closing (controlling) the fluid passage, the block portion of the main body is gripped by the upper cover from the upper side thereof, and the lower cover is held from the lower side. Between the main body and the upper cover and between the main body and the lower cover, heat medium spaces are respectively arranged, and the thermal medium passage connecting the heat medium spaces is disposed inside the main body, thereby causing The actuator is of a prior art and a heating or cooling configuration can be obtained. The heat medium flowing through the heat medium passage may be warm water (for heating), cooling water (for cooling), steam, or other liquid or gas (liquid or heat conductivity that is easy to vaporize) Good fluid, etc.). On the main body, a coating film is applied to a portion that contacts the heat medium in response to the need (in view of the type of the heat medium, etc.). The coating film is applied only to the surface of the body, and 201027017 can be applied not only to the surface of the body but also to the flow path of the heat medium passage (the entire surface of the heat medium contact). The heating means of the fluid controller, although the planar heater is used more often, but the power is necessary and difficult to adopt, and from the viewpoint of energy saving, it is also desirable to use the heating of the high-temperature drainage, the fluid of the present invention. The controller is suitable for such use. The body of the fluid controller, for example, is made of stainless steel such as SUS316 or 316L. Although the lower cover and the upper cover can be made of stainless steel such as SUS316, the present invention is not limited thereto. Since a plurality of thermal medium passages are disposed inside the body, the efficiency of heating or cooling becomes higher as compared with heating or cooling only from the outside of the main body. Further, by adjusting the number of the heat medium passages and the diameter of each passage, the pressure loss can be reduced. Further, when it is applied to an existing fluid controller, it is necessary to change the outer shape and the addition of the upper and lower covers. However, the internal configuration (the configuration other than the heat medium passage) can be used as it is, and the G can be easily used. Thermal media for fluid controllers that perform efficient heating or cooling. EFFECT OF THE INVENTION According to the fluid controller of the present invention, since the heat medium passage is formed inside the block portion of the body, the efficiency of heating or cooling becomes high, and by adjusting the number of the heat medium passages and the diameter of each passage , can reduce the pressure loss.

The outer circumference is formed as a regular square column, and the inner circumference is formed into a cylindrical surface. The top surface of the block portion 3 of the body 2 is attached to the bolt 13 inserted above the four turns. The lower cover 201027017 12 is formed with a lower heat medium space S2 for holding a heat medium between the bottom surface of the block portion 3 of the main body 2, and is formed as a seat body having a regular square column having a recess 25, and is used to be inserted into The bolts 14 below the four turns are mounted on the bottom surface of the block portion 3 of the body 2. The upper cover 11 is provided with a heat medium introduction joint 15 for introducing a heat medium therein, and the lower cover 12 is provided with a heat medium discharge joint 16 for discharging the heat medium from the inside. Here, although the joints 15 and 16 are formed as the lock joints using the φ metal ferrules 15a and 16a, it is of course possible to use other joints. As shown in Figs. 3 and 4, the cylindrical portion 4 of the main body 2 has a small diameter portion 21 connected to the top surface of the block portion 3, and a large diameter portion 22 connected thereto. The outer diameter of the large diameter portion 22 is formed to be smaller than the diameter of the top surface of the block portion 3 (the length of one side of the square), and the outer diameter of the small diameter portion 21 is formed to be larger than the large diameter portion 22. The outer diameter is smaller, whereby the upper heat medium ❿ space S 1 can be secured between the outer peripheral surface of the upper cover 11 and the inner peripheral surface of the upper portion of the small diameter portion 21. The inner diameter of the upper cover 11 is equal to the outer diameter of the large diameter portion 22 of the cylindrical portion 4, and the lower surface of the upper heat medium space S1 is defined by the top surface of the block portion 3, and the upper surface of the upper heat medium space S1. It is defined by the lower surface of the large diameter portion 22 of the cylindrical portion 4. The upper surface of the upper cover 11 and the upper surface of the large diameter portion 22 of the cylindrical portion 4 are formed in the same plane, and are pressed downward by the flange portion 6a of the sealing gland 6. An ankle ring 23 for sealing is provided between the outer peripheral surface of the lower end portion of the large diameter portion 22 of the cylindrical portion 4 and the inner peripheral surface of the upper cover 20102701711. The top portion of the block portion 3 has an outer diameter equal to the diameter of the inner peripheral surface of the upper cover 11, so that the lower end portion of the upper cover 11 can be fitted, between the outer peripheral surface of the top portion of the block portion 3 and the inner peripheral surface of the upper cover 11. There is also a ring 24 for sealing. A cylindrical recess 25 is formed in the top surface of the lower cover 12. The lower heat medium space S2 is formed by the circumferential surface and the bottom surface of the recess 25 and the bottom surface of the block portion 3 of the body 2. The diameter of the circumferential surface of the recess 25 is made smaller than the diameter of the inner circumferential surface of the upper cover 1 1 . An annulus 26 for sealing is present between the peripheral portion of the top surface of the lower cover 12 and the outer peripheral portion of the bottom surface of the block portion 3. In the block portion 3, a plurality of heat medium passages 27 for penetrating the block portion 3 up and down are provided so as to surround the pitch circle of the small diameter portion 2 1 of the cylindrical portion 4. The upper end of the heat medium passage 27 passes between the outer peripheral surface of the small diameter portion 21 and the inner peripheral surface of the upper cover 11, that is, passes through the upper heat medium space S1, and the lower end of the heat medium passage 27 passes through the recess 25 of the lower cover 12. That is, through the lower heat medium space S2. © In Fig. 5, in the block portion 3 of the main body 2, as shown by the broken line in the same figure, there are all fluid passages 3a from the left to the right of the figure, and the heat medium passage 27 does not interfere with the fluid passages 3a. In the manner of three, each of the three is disposed opposite to each other across the fluid passage 3a. Accordingly, the heat medium introduced from the heat medium introduction joint 15 of the upper cover 11 passes through the upper heat medium space S1, the plurality of heat medium passages 27, and the lower heat medium space S2, thereby forming the heat medium discharge joint 16 from the lower cover 12. Exhausted heat medium circulation path. The heat medium can also be introduced from the heat of the lower cover 12, the 201027017 medium discharge joint 16, and discharged from the heat medium introduction joint 15 of the upper cover 11. In the fluid controller 1, since the fluid is thermally expanded and cooled by the heat expansion from the high pressure to the low pressure, the main body 2 is cooled, so that the moisture in the ambient air is dew on the outer surface, and the condensation prevention is a problem. In this case, if warm water is used as the heat medium, the fluid controller 1 can be efficiently heated to prevent condensation. Further, if the cooling water is used as the heat medium φ body, the fluid controller 1 can be cooled. INDUSTRIAL APPLICABILITY According to the present invention, in a fluid controller requiring heating or cooling from the outside, if warm water is used as the heat medium, the fluid controller 1' can be efficiently heated to prevent condensation, for example, If the cooling water is used as the heat medium, the fluid controller can be cooled, so that a fluid controller that is effectively heated or cooled using the heat medium can be obtained.
