Problems solved by technology

[0007] The ball and the glass valve seat as the intermediate member are interposed between the valve core and the glass valve. However, if the stem portion is extended to the vicinity of the glass valve and the intermediate member is omitted, when the valve core is opened, the tip of the stem portion and the glass valve The stop screw collides and cannot move any further, and the valve part that stays inside the main body due to the lock may become a resistance to flowing water

[0048] The first embodiment ( Figure 1 to Figure 7 )

[0049] figure 1 The shown nozzle connection joint T1 has a main body 10 , a spool 20 , an outflow port 30 and a thermal decomposition part 40 .

[0050] The nozzle connection joint T1 is set at figure 2 Shown on sprinkler equipment. The main body 10 of the nozzle connection joint T1 is cylindrical, and the pipe P1 is connected to the one end side 11, and the thermal decomposition part 40 is attached to the other end side 12. An outflow port 30 is formed between the one end side 11 and the other end side 12 , and an open type shower head S2 is connected to the outflow port 30 via a pipe 31 .

[0051] An annular valve seat 13 is formed between the one end side 11 of the main body 10 and the outflow port 30 . The inside of the valve seat 13 is a flow passage, but a valve body 20 is provided on the surface of the other end side 12 of the valve seat 13 to block the flow passage.

[0052] The spool 20 has a disk-shaped d...

[0081] The second embodiment ( Figure 8 )

[0082] Next, refer to Figure 8The head connection joint T2 of the second embodiment will be described. In addition, the same code|symbol is attached|subjected to the same part as the structure of 1st Embodiment, and detailed description is abbreviate|omitted. Figure 8 The head connection joint T2 of the second embodiment shown is a structure without the screw 51 of the head connection joint T1 of the first embodiment.

[0083] The saddle 61 of the second embodiment has a U-shaped cross section and has two erected portions 61A. The surface between the erected portions 61A, 61A is a contact surface that contacts the lever 42 . The surface on the opposite side to the contact surface with which the lever 42 contacts is in contact with the rod 62 .

[0084] The tip of the rod 62 is processed into a spherical shape, and a mortar-shaped recess 63 is formed at a portion of the rod 62 that contacts the saddle 61 . The other end of th...

Abstract

The invention provides a spray head connecting joint, in a condition of long moving distance of a valve element, the length of a valve rod part is unlimited, and the valve element does not block the flow. The spray head connecting joint comprises a main body (10) which is in cylinder-shaped and of which one end side (11) is connected with a water supply piping and the other side (12) comprises a heat-sensitive decomposition part (40), an outflux (30) which is formed on the middle part of the main body (10), and the valve element (20) which blocks between one end side (11) and the outflux (30) and is opened through the movement of the heat-sensitive decomposition part (40), wherein the heat-sensitive decomposition part (40) can clip at a step part (53) which is arranged in the other end side (12) of the main body (10), a holding component is arranged between the valve element (20) and the heat-sensitive decomposition part (40), the holding component can hold the heat-sensitive decomposition part (40) on the step part (53) and can hold the valve element (20) on a closing position.

Description

technical field [0001] The present invention relates to a nozzle connection joint. The nozzle connection joint is a joint connected to a fire extinguishing equipment pipe, and a nozzle is connected to an outlet of the joint. Background technique [0002] In sprinkler installations, sprinklers are installed at predetermined intervals on or near the ceiling. However, if there is an obstacle such as a pipe under the portion where the shower head is installed, the pipe may hinder water spraying. For example, a head mounting tool described in Patent Document 1 may be used at such a location. [0003] The nozzle installation tool described in Patent Document 1 has: a main body with a pipe connection port at one end, a heat sensitive part installation port at the other end, and a nozzle connection port formed between the two ends; Blockage between the inner piping connection port and the nozzle connection port. The installation port is provided with a heat-sensitive part which s...
