Abstract

PURPOSE:To efficiently bury a stop cock by burying a stop cock having a packing gland and a spindle longer than the defined values into a building framework body, and adjusting these length according to the surface position of the framework body. CONSTITUTION:A packing gland 40 and a spindle 22 constituting a stop cock main body 10 are formed longer than customary ones, and the main body is buried in a building framework body 54. According to that the extreme end face of the trunk part 20 of the stop cock 10 is on the surface position 100 or 200 of the framework body, the length of the packing gland 40 and the spindle 22 are adjusted and cut off at the positions 101, 102 or 201, 202. Next, a wan seat 42 is fitted to the packing gland with a dish presser 44, hereafter a handle 50 is fitted to the spindle 22. Hereby, even though the extreme end position of the trunk part 20 of the stop cock main body 10 is a little different against the surface of building framework body, the stop cock fitting work can be easily executed.

In FIG. 2, an inlet 12 is provided at one end of the stopcock body 10.
is provided, and an outlet 14 is provided at the other end. Inside the stopcock body 10, there are an inlet 12 and an outlet 1.
A partition wall 16 is integrally provided to separate the
A valve hole 18 is formed in the partition wall 16 .

A body portion 20 extends from a side portion of the stopcock body 10. A spindle 22 is inserted into the body 20, and a valve body 24 is attached to the tip thereof. This valve body 24
The spindle 22 includes a piece 28 inserted into a shaft hole 26 drilled in the axial direction from the distal end surface of the spindle 22, and a piece packing 32 attached to the piece 28 via a piece nut 30.

A female screw is carved into the inner periphery of the tip of the body portion 20, and a cylindrical packing box 34 is screwed thereto.

Reference numeral 36 indicates a packing sandwiched between the flange 34a of the packing box 34 and the front end surface of the lugs 20.

The spindle 22 is inserted into the packing box 34, and a male screw carved on the outer peripheral surface of the spindle 22 and a female screw formed on the inner peripheral surface of the packing box 34 mesh with each other, so that the spindle 22 can move forward and backward in the direction of its axis.

A U packing 38 is interposed between the inner circumferential surface of the packing box 34 and the outer circumferential surface of the spindle 22.

A packing holder 40 is screwed into the packing box 34 in order to fix the packing 38. This packing holder 40 has a cylindrical shape, and a female screw carved on the outer peripheral surface is screwed into a female screw on the tip side of the packing box 34.

A female screw is engraved on the inner circumferential surface of the packing presser 40.

A dowel seat 42 is placed so as to cover the tip of the trunk 20, and the dowel seat 42 is fixed to the packing presser 40 by a dowel presser foot 44. The one-piece presser foot 44 is bolt-shaped with a center hole, and the male thread on the outer circumferential surface is screwed together with the female screw of the seal presser foot 40. The spindle 22 is inserted into the center hole of the one-piece presser foot 44.

The upper end portion of the spindle 22 in FIG. 2 has serrations 4.

In the long body water stop valve configured in this way, the building frame 5
A stopcock main body 10 is buried in the tank 4 so that the tip of the body part 20 is almost flush with the frame surface.

In addition, when this building frame is tiled, for example, the tile surface becomes the frame surface.

After the water stop faucet main body 10 is buried in a building frame 54, a dowel seat 42 is covered and fixed with a dowel holder 44, and then a handle 50 is fixed to the spindle 22 with an indicator screw 52.

Note that when you grab and turn the handle 50, the spindle 22
moves forward and backward in the direction of its axial center column, and the piece seal 3 of the valve body 24
2 is seated on the opening periphery of the valve hole 18 to shut off water. Moreover, when the top packing 32 separates from the opening periphery of the valve hole 18, water flows in an amount corresponding to the separation distance.

[Problems to be Solved by the Invention] In the above-mentioned conventional construction method for a long-body stop valve, construction is performed so that the surface of the building frame 54 (for example, the tile surface) is about ±5 mm from the tip surface of the body 20. There is a need to. That is, if the body part 20 retreats excessively from the building frame surface, the one-piece presser foot 44 may not be able to reach the female screw of the seal presser foot 40, or the handle 50 may not cover the spindle 22.

Conversely, if the trunk 20 protrudes excessively from the building frame surface, the dowel seat 42 will float off the building frame surface.

For this reason, in the conventional construction method for long-body water stop valves, it is necessary to construct the body part 20 so that its tip end surface is at an appropriate position with respect to the building frame surface, and the construction requires skill. It was easy to use, and the work time was long.

[Means for Solving the Problems] A method for constructing a long-body stopcock of the present invention includes an inlet provided at one end, an inlet provided at the other end, and a separation between the inlet and the outlet. A water stop valve main body comprising a partition wall, a valve hole provided in the partition wall, and a body protruding laterally, a cylindrical packing box screwed onto the tip side of the body, and a valve coaxial with the packing box. A packing holder screwed into the packing holder, a spindle inserted through the packing holder and the packing box and screwed onto the packing box so as to be able to be screwed into the packing box in an axial direction, and a handle attached to one end of the spindle. and a valve body for opening and closing the valve hole provided at the other end of the spindle. In a method of constructing a long-body stopcock in which the body of the stopper is buried in the building frame and a one-piece seat is mounted on the body, the stopper and spindle are set to a predetermined length or longer, and the stopcock is installed. After burying the main body and trunk in the building frame, the packing retainer and spindle are cut in line with the position of the building frame, and then the one seat is attached to the tip of the body and the handle is attached to the spindle. It is characterized by:

[Function] In the construction method of the long-body water stop valve of the present invention, the spindle and the seal retainer are cut according to the positions of the building body surface and the body end surface, so that the body is attached to the building body. The one seat and the handle can be reliably and properly attached even if the body protrudes considerably from the surface, or conversely, even if the body is considerably retreated from the building frame surface.

[Example code] Examples will be described below with reference to the drawings.

FIG. 1 is a procedure diagram illustrating an embodiment method of the present invention.

In this embodiment, the seal holder 40 and the spindle 22 are considerably longer than the conventional example shown in FIG. Note that other symbols in FIG. 1 indicate the same parts as in FIG. 2.

When constructing this long-body stop valve, the stop valve main body 10 is first buried in the building frame 54. Thereafter, the packing holder 40 and the spindle 22 are cut according to the surface 100 or 200 of the body 54.

In this case, for example, the front end surface of the body 2o is connected to the building frame surface 10.
0, the spindle 22 is cut near its tip, as shown by the reference numeral 101 in the figure, and the seal retainer 40 is also cut off, as shown by the reference numeral 102, in the same way.
Cut near the tip.

On the other hand, if the skeleton surface of the building is constructed as shown at 200 and the tip end surface of the body 20 protrudes considerably from the skeleton surface 200, the spindle 22 is moved far away from the tip side as shown at 201. Similarly, cut the packing presser 4o at a position M (code 202) quite far from its tip.
Cut with.

In this way, the surface position of the building frame 54 is 100.200.
After adjusting the lengths of the spindle 22 and the packing presser 40 according to the requirements, the one-piece seat 42 is attached to the packing press 4o with the one-piece presser 44, and then the handle 50 is attached to the spindle 22 with the indicator screw 52.

In this way, even if the surface position of the building frame 54 is significantly different from the normal finished position, the one seat 42 and the handle 50 can be properly attached. Of course, the dowel seat 42 is definitely connected to the surface 10 of the frame 54.
0 or 200, and the handle 50 is also very firmly attached to the tip of the spindle 22.

As shown in FIG. 1, the serrations 46 are extended long on the tip side of the spindle 22, and the serrations allow the handle 50 to be attached even if the spindle 22 is cut at any position. so that it remains in Further, a female thread is carved on the inner circumference of the packing presser 40 over a sufficiently long range, and the sealing presser 40 is
No matter where the 0 is cut, the one presser foot 44 is made to be able to fit securely.

[Effects] As described above, according to the construction method of the long body stop valve of the present invention,
To be able to securely and appropriately attach a one-piece seat and a handle even when the construction is performed so that the tip of the body section is considerably offset from the building frame surface. Therefore, the difficulty level of the work of embedding the stopcock body is alleviated, and the work is also speeded up.
