の助成に効果的な活用が図れる。 An object of the present invention is to provide a thermostatic steam trap having a valve hole consisting of a small diameter hole sandwiching a conical seat and a relatively large diameter hole, and a plurality of communication holes on the inner surface of the large diameter hole. The valve seat member provided includes a conical valve surface that is seated near the small diameter hole of the conical seat, a protruding leg that extends loosely in the small diameter hole, and a body that extends into the large diameter hole and has a conical collar facing the opening of the flow hole. The valve element is assembled, the valve element is fitted into the large diameter hole of the valve seat member, the body of the valve element is rotatably housed, and the bimetal column is locked to a stem that has a holding hole at one end that abuts against the conical brim. By holding the bimetal column in the set position with the inner end of the threaded adjustment tube, which loosely accommodates the other end of this stem,
This can be advantageously achieved by the protruding legs of the valve moving in the small diameter hole of the valve seat member each time the valve is opened and closed, thereby stimulating the cleaning and shedding of the adhered scale.
Here, since at least one of the protruding legs and the conical brim of the valve has a spiral cut, the swirling flow of the condensate flow due to the warping can be effectively utilized to assist the action of the movement of the protruding legs.

図ａ，ｂのような弁子５を組合わせる。 As shown in FIG. 2, the valve seat member 3 has a valve hole 4 consisting of a small diameter hole 3b sandwiching a conical seat 3a and a relatively large diameter hole 3c. The conical valve face 5a is seated closer to the small diameter hole 3b of the conical seat 3a, the protruding leg 5b extends loosely within the small diameter hole 3b, and the opening of the communication hole 3d is provided with a plurality of communication holes 3d opening on the inner surface of the Facing conical brim 5
c and a body 5d extending into the large diameter hole 3c.
Combine valves 5 as shown in Figures a and b.
弁子５はその突脚５ｂおよびまたは円錐つば５

８に保持する。 One end of the stem 7 is fitted into the large diameter hole 3c of the valve seat member 3 so as to be able to slide against it, and the stem 7 loosely accommodates the body 5d of the valve element 5 to the conical collar 5c and its back surface. A retaining hole 7a is made so that they meet, and the slightly enlarged head 7b at the other end of the stem 7 is held in a screw type adjustment tube 8 having a blind hole 8a in which it is loosely accommodated.

弁子５の変位として伝えるのである。 The stem 7 has a bimetal column 6 and a retaining ring 10.
The thermal expansion of the bimetal column 6 is applied as a displacement of the stem 7 and the valve element 5 via the retaining ring 10 under the reaction force support of the screw type adjusting cylinder 8. It is to convey it.
従つて入口１に到来した復水の温度が低いと
き、その復水は弁子５を排して弁孔４を通り抜
け、端部材１２のスパイダ開口１２ａから出口２
を流過する。 Therefore, when the temperature of the condensate that has arrived at the inlet 1 is low, the condensate discharges the valve 5, passes through the valve hole 4, and flows through the spider opening 12a of the end member 12 to the outlet 2.
flow through.

に達しない間にはこの例で復水の連続排出が行わ
れることとなる。 The gradual increase in the temperature of the condensate while being carried away by the succeeding steam thus causes a corresponding expansion of the bimetallic column 6, as already mentioned,
Finally, the valve element 5 closes the valve hole 4, and it is clear that the valve closing temperature can be arbitrarily set by adjusting the adjustment position of the screw-type adjustment tube 8, so that the valve closing temperature is not reached until this valve closing temperature is reached. In this example, condensate will be continuously discharged.

きる。 In this way, various impurities that may be contained in the condensate, especially fine particles of iron oxide generated due to corrosion of the piping, pass through the inlet side strainer 14 and accumulate around the valve hole, causing scale adhesion. However, when the valve element 5 moves forward and backward each time the valve is opened and closed, the projecting leg 5b of the valve element 5
moves within the small-diameter hole 3b of the valve seat member 3, thereby changing the flow situation, thereby causing fluctuations in the flow force that are useful for preventing scale deposition. That is, due to this change in flow, the accumulated scale is washed away before it can firmly adhere to the valve portion or the like. When the protruding leg 5b or the conical collar 5c is provided with spiral notches 5e and 5f as shown in FIG. However, more effective prevention of scale adhesion can be realized.

いを有利に軽減できる。 Thus, according to the invention, the condensate discharge flow is
By moving the protruding legs provided on the valve element in the small diameter part of the valve hole while the valve is in operation, scale stagnation that tends to adhere to the valve hole is swept away, and even when the valve hole is small. The problem of clogging can be advantageously reduced.
