(Partition wall 26)

The partition walls 26 are disposed transversely with a predetermined angle (? In this embodiment) on both sides and the upper surface of the cylindrical body 25 to determine the position of the main valve body 27.

The partition wall 26 has a predetermined thickness and is formed into a door shape by the side portions 26a and the upper portion 26b to form a rectangular opening 26c in the door shape. The bottom of the opening 26c serves as the inner surface of the cylindrical body 25 and has a curved surface shape.

Thus, the main valve body 27 is kept in the closed state at the predetermined position and is pivotally closed (valve closed, closed valve) through the pin in the opening 26c. Therefore, the first pin holding body 33 is provided so as to protrude from the front portion of the partition wall 26 so as to protrude from the front of the partition wall 26, and on the upper portion of the main valve body 27, (34) are provided so as to protrude, and a pin (35) is pivotally mounted therebetween.

(Main valve body 27) (see Figs. 4 and 5)

The main valve body 27 closes the opening 26c of the partition 26 at the valve closing position and opens the valve 35 forward to open the valve. The lower end of the main valve body 27 forms an arc and seats on the front end face 25a of the cylindrical body 25. [ The stop position of the main valve body 27 is determined. Also, the lower end of the main valve body 27 is not projected beyond the front end face 25a of the cylindrical body 25. The lower end of the main valve body (27) may be seated in the cylindrical body (25).

A stopper 37 is attached to the partition wall 26 along both side edges of the front portion of the main valve body 27 and is attached to the front of the partition 26 (Sitting). The stop of the main valve body 27 is determined by abutting against the front end surface 25a of the cylindrical body 25 at the tip end and abutting against the partition wall 26 of the stopper 37. [

A cut recessed portion (38) having a rectangular shape is formed at the upper edge of the main valve body (27). It may also be in the form of a window.

The position of the pin 35 of the main valve 27 in the present embodiment is such that when the deodorizing device S for the present sewer pipe is installed in the pipe 6, Take the water depth position. When the distance between the attachment pipe 6 and the cylindrical body 25 can be ignored, it is 80% of the length of the pipe body of the cylindrical body 25.

(The sub-valve body 28) (see Figs. 4 to 6)

The auxiliary valve body 28 is arranged to close the upper recessed portion 38 of the main valve body 27 from the rear surface of the main valve body 27 and operates in the valve opening direction of the main valve body 27, But the valve is opened against excessive wind pressure from the sewer pipe.

As a result, the sub-valve body 28 swings about the pin 41.

A frame body portion 42 protrudes from the notched recessed portion 38 on the rear surface of the main valve body 27. The frame body portion 42 is composed of a lower face plate 42a of the lower face which is opposed to the cut recessed portion 38 and a side wall portion 42b which faces the cut recessed portion 38. The inner surface of the lower end of the sub-valve body 28 abuts against the end surface 42c of the lower plate portion 42a and serves as a stopper of the sub-valve body 28. In other words, the valve closing position of the sub-valve body 28 is determined. The side wall portion 42b forms a triangular shape and closes the lateral direction of the sub-valve body 28 in the valve closed state of the sub-valve body 28. [

The sub-valve body 28 is preferably made of a hard material and closes the frame portion 42 with its own weight and does not move under a weak wind pressure.

In this embodiment, the valve closing angle? (Inclination angle of the main valve body 27) of the sub-valve body 28 is 2?, That is? = 20 占 and? = 40 占 when? = 20 占.

Therefore, when α = 20 °, the valve closes 20 ° to the forward direction of the main valve body 27, and the subsidiary valve body 28 assumes the valve closed state to the reverse 20 °. Due to this, the sub-valve body 28 can maintain the valve closed state until the main valve body 27 assumes a valve-closed state of 20 °. In other words, if? Is in the range of? To 2? (20 to 40), the valve closed state of 0 to? (0 to 20) is maintained.

The sub-valve body 28 can take the following aspects in addition to the above-described configuration.

1. A rectangular window is formed on the upper portion of the main valve body 27 and the respective constituent members 39, 40, 41 and 42 of the sub-valve body 28 corresponding to the window, .

2. The window 1 is provided on the partition wall 26 and serves as a sub-valve body 28. In this embodiment, the sub-valve body 28 needs to obtain a sealing action in a vertical state.

3. The partition wall 26 is attached to the main valve body 27 at an appropriate position (for example, at a water depth of 8%) with only the two side portions 26a without the upper portion 26b, And serves also as a sub-valve body 28.

4. A weight for imparting a backward force to the sub-valve body 28 is additionally provided and is operated in accordance with the valve opening direction of the main valve body 27 to close the valve However, the valve is opened for excessive wind pressure in the sewer pipe.

The spacer ring (spacer ring) 31 is a cylindrical body having a predetermined thickness and flexibility, and is fitted to the rear portion of the cylindrical body 25 of the body portion 12. The thickness of the spacer ring 31 is sufficient to close the gap between the spacer ring 31 and the attaching tube 6 to be set, and is appropriately determined by the inner diameter of the attaching tube 6.

Thus, the spacer ring 31 maintains the watertightness of the cylindrical body 25 and the attaching pipe 6, while maintaining the center of the cylindrical body 25. The spacer ring 31 may also be omitted.

The link portion 14 (see Figs. 2 and 9)

The link portion 14 is mounted as a one-node link on both sides of the inlet frame portion 10 and the main body portion 12.

The connecting plate 50 is disposed between the bracket 21 of the inlet frame portion 10 and the rear portion of the cylindrical body 25 of the main body portion 12. The connection plate 50 is bent between the opposite ends of the connection plate 50 because the proper spacing between the opposite sides of the connection plate 50 is different.

Material ( material )

A rigid and watertight material is used for the material of the deodorizing device (excluding the spacer ring 31). Synthetic resin materials meet this requirement and are recommended to be recommended in light weight, but they do not exclude other materials such as metals.

Installation mode

In this embodiment, in particular, it is assumed that the mounting angle? Of the mounting tube 6 is about 20 deg., And as described above, the angle of the valve corresponding to the angle?, I.e., the valve closing angle? , The valve closing angle? Of the sub-valve body 28 is set. However, it is not limited to this.

5, X represents a horizontal reference line, and Y represents an axial center of the attachment pipe 6, and furthermore, the axial center of the cylindrical body 25. [

In addition, the configuration of the present deodorizing apparatus S is changed in accordance with aspects of the sewage pipe conduit M, the pipe 6, and the like.

That is, when the sewer pipe M is sewn into a rectangular shape, the inlet frame portion 10 takes the form of a flat frame instead of the curved frame described above.

(Operation of the present embodiment)

The present deodorizing apparatus S having the above-described configuration is attached to the pipe 6 from the sewage pipe M in the following manner, and exhibits a drainage and a deodorizing function as a scavenging function.

In the embodiment, the deodorizing device S is formed by integrally combining the inlet frame portion 10, the link portion 14, and the main body portion 12.

Mounting (裝着) (see Fig. 2)

The main body portion 12 of the deodorization apparatus S is placed in the drainage port 5 of the installation pipe 6 and the main body portion 12 is positioned at the head of the installation pipe 6 And the main body portion 12 is pushed in by manual operation with or without an operating mechanism. The attaching tube 6 is inclined downward at a predetermined angle?, And the attaching tube 6 Is a small diameter and the guide ring 30 mounted on the front end of the main body portion 12 smoothes the insertion operation. In other words, the engaging portion 45a of the tapered portion 45 of the guide ring 30 is inserted into the drain port 5 of the attaching tube 6, So that insertion can be smoothly performed. The center of the attaching tube 6 is held by the pressing action of the pressure-receiving portion 46 to the inner wall of the attaching tube 6 at the pushing-in of the body portion 12. [

The main body part 12 is further pushed in and the main body part 12 pulls the inlet frame part 10 through the link part 14. [

The inlet frame portion 10 comes close to the drain port 5 and the frame 20 and the inserting portion 23 are inserted into the drain port 5. Further, the flange portion 22 of the frame body 20 is engaged with the drain hole 5. Due to this, the inlet frame portion 10 is attached at a predetermined position.

The main body part 12 is connected to the inlet frame part 10 and the link part 14 in a flexible manner so that the body part 12 can be freely moved corresponding to the inclination of the attaching pipe 6. [ (6).

Valve closing action ㆍ deodorizing action

The deodorizer (S) is attached in a predetermined state in the pipe (6) and always maintains the valve closed state.

That is, in the main body 12, the main valve body 27 closes the opening 26c of the partition 26 in a vertical state. This valve closing action is free of dead movement due to the self weight of the main valve body 27. [

Further, the sub-valve body 28 closes the opening of the main valve body 27, that is, the cut recessed portion 38, in a vertical to inclined state. Due to the magnetic weight of the valve closing member 28, there is no idle operation. The gap between the attachment tube 6 and the body portion 12 is sealed by the spacer ring 31. [

The odor of the sewerage main pipe P is blocked by the valve closing of the main valve body 27 and the sub valve body 28. [

Drainage

The deodorizer (S) is attached to the pipe (6) in the above-described state, and drains when the water flows in.

Now, in the case of rain, the rainwater flows into the drainage pipe (M) of the sewage pipe as the rainwater, is filled in the drainage port (5), and is discharged from the installation pipe (6) to the sewerage main pipe (P).

The water flows easily by opening and lowering the main valve body 27 with water pressure. The auxiliary valve body (28) operates in accordance with the valve opening operation of the main valve body (27). When the water flow rate is small, the opening of the main valve body 27 is also small, so that the sub valve body 28 maintains the valve closed state with respect to the notch recessed portion 38 as the opening. Therefore, the above-mentioned deodorizing action continues.

In this embodiment, the caulking portion of the main valve body 27 substantially occupies 80% of the diameter of the pipe 6 and is efficiently drained to a large amount of water.

Reverse wind pressure action

When the air pressure in the sewer main pipe P becomes abnormally high, in the main deodorization apparatus S, the auxiliary valve body 28 opens and this air pressure is lost. This operation also takes place in the drainage of the main valve body 27.

(Effects of the present embodiment)

According to the deodorizing apparatus S of the present embodiment, the insertion operation can be easily performed in the mounting operation on the mounting tube 6, the working effect can be improved, and the angle of the mounting tube 6 can be easily And it is not necessary to manufacture it every time according to the angle of the attaching pipe 6, and it is freed from the limitation of manufacturing. In addition, after the attachment, the valve is always closed so that the deodorizing action and the influx of the flowing water and the reverse wind pressure action can be reliably coped with.

The hinge pipe 76 is the same as the engaging means of the previous embodiments. The arm portion 75 is concentric with the cylindrical body 25A and has the same radius (curvature). The arm portion 75 is inclined at a predetermined inclination angle? Downward from the tube axis of the cylindrical body 25A in the vertical projection plane in the present embodiment, but may be the same as the tube axis. The diameter of the hinge pipe 76 is larger than the diameter of the drain hole 5 of the mounting pipe 6 to be mounted and is caught around the drain hole 5.

 Further, since the arm portion 75 is inclined downward from the tube axis of the cylindrical body 25A, there is a margin for the engagement of the hinge pipe 76 with the drain hole 5. In this embodiment, the inclination angle &thetas; is about 15 DEG. In the drawing, 76a is an inner hole of the hinge pipe 76. In the ceramics, the inner hole 76a is a through hole, but it is not necessary to have a blind hole or a hole.

An annular protruding ring 77 is formed in the circumferential direction on the outer side of the cylindrical body 25A and the position of the spacer ring 31 fitted and fixed to the outer circumference of the cylindrical body 25A is determined . The function of the spacer ring 31 is as described above. In other words, the spacer ring 31 distinguishes the hardness by color, and the ceramic ring of the attachment pipe 6, It corresponds to a vinyl pipe. That is, the pottery tube has no slip compared to the vinyl chloride tube, and the spacer ring 31 is made of soft material. In the cylindrical body 25A, the main valve body 27A is disposed in such a manner that the main valve body 27A is covered on the entire surface of the partition wall 26, in spite of the structure of the foregoing embodiment.

In addition, ABS resin is preferably adopted as the material of the cylindrical body 25 and the partition wall 26.

(Design change items in each embodiment)

The present invention is not limited to the above-described embodiment, and various design changes are possible within the scope of the basic technical idea of the present invention. That is, the following aspects are included in the technical scope of the present invention.

 1) The partition wall 26 provided in the cylindrical body 25 of the main body part 12 is protruded in the cylindrical body 25 and becomes water resistance. This is conspicuous when the inclination angle alpha of the attachment pipe 6 is gentle (gentle slope).

18, it is preferable to form the water supply wall portion 80 on the upstream side of the partition wall 26, in other words, on the rear portion of the partition wall 26. [ The drawing is shown with respect to a central cross-sectional portion, and a water-resistant wall portion 80 is provided extending vertically. Reference numeral 80A denotes a water supply wall portion formed to the middle of the opening 26c, and 80B denotes a water supply wall portion formed just before the opening 26c. The surface 80a of the waterproof wall portion 80 is flat in the drawing, but may be curved.

In the drawing, the main valve body 27 is opened and the flowing water flowing in the Z direction smoothly flows into the opening 26c along the surface 80a of the water supply wall portion 80. [

Needless to say, the water supply wall portion 81 can be provided on the downstream side of the partition 26, that is, on the front portion of the partition 26, as indicated by the chain line in Fig.

2) The sub-valve body 28 can take the following aspects in addition to the configuration of the foregoing embodiment.

a. A rectangular window is formed on the upper portion of the main valve body 27 and the respective constituent members 39, 40, 41, 42 of the above-described sub-valve body 28 corresponding to the window portion ).

b. A window of the a is provided on the partition wall (26) and serves as a sub-valve body (28). In this embodiment, it is only necessary that the sub-valve body 28 can obtain a sealing action in a vertical state.

c. A weight for imparting a reverse force to the sub-valve body 28 is added to the valve body 28 and the valve body 28 is operated along the valve-opening direction of the main valve body 27 to give a valve closing action. Fig. 19 shows an embodiment of such an example. Reference numeral 38 denotes an opening formed in the main valve body 27, that is, a valve hole for the sub-valve body; and 39, a pin holding body projected from the main valve body 27. The sub-valve body 28 rotates around the pin 85 held by the pin retainer 39 and is always energized in the valve closing direction by the weight 86 at the end, .

3) In each of the above-described embodiments, the main valve body 27 is attached in correspondence with the angle? Of the attachment pipe 6 and the design attachment angle? Of the main valve body 27 (normally? The main valve body 27 which maintains the vertical state is in contact with the partition wall 26 when the angle? Of the attachment pipe 6 is higher than the attachment angle? A gap is created between the valve seat 26c and the valve seat 26c and the valve closed state can not be maintained. Therefore, the desired action (deodorizing action) can not be achieved.

In order to prevent this, as shown in Figs. 20 to 22 again in the third embodiment, a mode of the valve closing power applying means for adding a spring body 90 that gives a power distribution action to the main valve body 27A .

That is, the spring body 90 serving as the valve closing force adjusting means is a spring portion 90a and an attaching base portion 90b. Through the bolt insertion hole 90c of the attaching base portion 90b, Bolt body, adhesive, etc.) to the upper portion 27a of the main valve body 27A. The spring portion 90a constitutes a functional portion and is disposed over the V-shaped groove 27c of the main valve body 27A. The spring portion 90a forms a circular arc in a cross-sectional shape, and its thickness is reduced (decreased) as it approaches the tip. That is, when the thickness of the attaching base portion 90b is h, the thickness of the base portion near the base of the spring portion 90a is i, and the thickness close to the tip is j, h > The distal end of the arc portion of the spring portion 90a projects beyond the extension of the attachment base 90b.

The spring member 90 has a trapezoidal shape in plan view. (Fig. 22). However, the present invention is not limited to this embodiment. A change in the thickness and width of the spring body 90 contributes to the adjustment of the elastic force.

The material of the spring body 90 may be a polyvinyl chloride resin (soft) or an ABS resin because of the characteristics (workability, economical efficiency, corrosion resistance, etc.) , Metal, or the like.

In a natural state, that is, in a no-load state, the distal end of the arcuate portion protrudes beyond the extension line of the attachment base 90b. However, in the state of maintaining the valve closing, the spring body 90 is bent, And abuts on the upper surface of the main body portion 27b. Therefore, when the spring body 90 does not have running water at all times, the main valve body 27A is pushed and held to maintain the valve closed state.

4) The structure of the main valve body 27A in the third embodiment also includes the matters described in 3) above, and can be applied to the first and second embodiments. The rear configuration of the third embodiment is also applicable to the second embodiment.
