Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a fire sprinkler head convenient for detecting the blockage of a fire protection system comprises a nipple 1 and a yoke arm frame 2, wherein the nipple 1 is fixed on a water supply pipeline of the fire protection system through a thread at the top end, the top ends of two support arms of the yoke arm frame 2 are fixedly connected with an annular plate 201, an expansion pipe 3 is fixedly connected between the top of the annular plate 201 and the bottom of the nipple 1, referring to fig. 2-3, the inner diameter of the expansion pipe 3 is larger than that of the annular plate 201, the inner diameter of the annular plate 201 is larger than that of the nipple 1, a positioning bolt 4 is sleeved in the middle of the bottom end of the yoke arm frame 2 through a thread, a glass tube 5 positioned between the two support arms of the yoke arm frame 2 is movably connected to the top end of the glass tube 5, a lower sealing plate 6 is movably connected to the top of the lower sealing plate 6, and the bottom of the annular plate 201, and the diameter value of the lower sealing plate 6 is larger than that of the annular plate 201, positioning bolt 4 through 2 bottoms of yoke cantilever crane is used for 2 threaded sleeve joints of yoke cantilever crane for glass tube 5 supports next shrouding 6, and then make the inboard of next shrouding 6 stable to annular plate 201 seal, the equal threaded sleeve in both sides at annular plate 201 top is equipped with back shaft 7, and two back shafts 7 are located the outside of expansion pipe 3, the first magnetic ring of top fixedly connected with of two back shafts 7, the outer second magnetic ring that is located first magnetic ring top of following fixedly connected with of 1 bottom of nipple, and the bottom of second magnetic ring is opposite with the top magnetic pole of first magnetic ring, the magnetic attraction of second magnetic ring to first magnetic ring is greater than normal water pressure in the water supply pipe.

After the fire sprinkler head is installed, the two magnetic rings are in an adsorption state through the magnetic attraction of the second magnetic ring to the first magnetic ring, at the moment, the expansion pipe 3 is in a compression state, the glass tube 5 enables the lower sealing plate 6 to be only attached to the bottom of the annular plate 201 for sealing through the supporting force of the lower sealing plate 6, when whether a water supply pipeline in a fire fighting system is blocked or not is detected, the water supply pressure of the fire fighting water pump is improved, the water pressure in the water supply pipeline overcomes the magnetic attraction of the two magnetic rings of the upper sealing plate 8, the first magnetic ring breaks away the magnetic attraction of the second magnetic ring, under the action of the water pressure, the annular plate 201, the yoke arm support 2, the lower sealing plate 6 and the glass tube 5 move down integrally, at the moment, the expansion pipe 3 is in a stretching state, then the initial water supply pressure of the fire fighting water pump is recovered, a detector only needs to push the long rod above the annular plate 201, if the annular plate 201 can be pushed up integrally, the first magnetic ring at the top of the supporting shaft 7 and the second magnetic ring at the bottom of the threaded connection pipe 1 are adsorbed together again, so that the situation that the fire sprinkler head and a water supply pipeline communicated with the fire sprinkler head are not blocked can be judged, if the annular plate 201 cannot be pushed to move upwards integrally, namely the first magnetic ring is not separated from the second magnetic ring, the expansion pipe 3 is still in a compression state, the situation that the fire sprinkler head and the water supply pipeline communicated with the fire sprinkler head are blocked can be judged, and therefore detection of the water supply pipeline of the fire sprinkler system and each fire sprinkler head by detection personnel is facilitated, the overall detection efficiency is improved, compared with the existing fire sprinkler head which is detected through water spray exercise, and an electronic detection device or an airflow detection device is additionally arranged, the problems that manual investigation consumes much time, manpower is large, the efficiency is low, wiring is unchanged, the cost is high and the like are solved effectively.

The bottom of the screwed pipe 1 is movably connected with an upper sealing plate 8, the diameter value of the upper sealing plate 8 is smaller than the inner diameter value of the annular plate 201, the upper sealing plate 8 is positioned at the inner side of the expansion pipe 3, a spring 9 is arranged between the bottom of the upper sealing plate 8 and the top of the lower sealing plate 6, the upper sealing plate 8 is used for plugging the bottom of the screwed pipe 1 under the elastic force action of the spring 9, the bottom of the annular plate 201 is plugged under the supporting force action of the glass pipe 5 of the lower sealing plate 6, under the condition of not influencing normal use and detection, double sealing is formed, the sealing effect when the fire sprinkler head is not used is improved, after the fire sprinkler head is not used due to long-term placement, if the sealing part of the lower sealing plate 6 and the annular plate 201 has a leakage problem, water in the expansion pipe 3 flows out, so that a detector can timely know, and excessive water in a water supply pipeline is avoided, causing waste of water resources and causing soaking damage to indoor objects.

Be equipped with telescopic link 10 between the middle part on 6 tops of lower shrouding and the middle part of last shrouding 8 bottoms, telescopic link 10 is located spring 9's inboard, connects last shrouding 8 and lower shrouding 6 through telescopic link 10 for go up shrouding 8 and only can be relative down 6 longitudinal movement of shrouding, ensure that go up shrouding 8 can not be relative down 6 level malposition of shrouding, the influence is to the condition of 1 shutoff of nipple.

When whether the water supply pipeline and the fire sprinkler head are blocked is detected, the water supply pressure of the fire pump ensures that the water pressure value in the water supply pipeline can enable the first magnetic ring and the second magnetic ring to break away, the initial water supply pressure of the fire pump is recovered after a certain time, then, a detector holds the long rod to the fire sprinkler head, and pushes the yoke arm frame 2 or the lower closing plate 6 upwards by the long rod from the lower part, so that whether the fire sprinkler head is blocked is judged according to whether the yoke arm frame 2 can be pushed upwards integrally and whether the expansion pipe 3 is in a stretching state or not; when the conflagration appears, the high temperature of flame makes the organic solvent inflation in the glass pipe 5, thereby break glass pipe 5, lose glass pipe 5's support back, under water pressure effect in the water supply pipe, make next shrouding 6, upper shrouding 8, spring 9, the whole whereabouts of telescopic link 10, with the separation of fire sprinkler head, water in the water supply pipe lasts the lower current, and through the splash box homodisperse of yoke arm frame 2 bottoms, act on the flame of below, realize the fire extinguishing effect, can.
