Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of portable water base fire extinguishing device, as shown in Figure 1-2, mainly comprises cylinder assembly 1, jet hose 2 and device head 3.Cylinder assembly 1 comprises cylindrical shell and is located at valve seat 11 on this cylindrical shell, cylindrical shell specifically comprise set gradually from top to bottom upper cover 12, stack shell 13, low head 14 and foundation ring 15.Be equiped with medicament in cylindrical shell, be inserted with the siphon pipe 4 be connected with device head 3 in cylindrical shell, device head 3 establishes pressure indicator.
The inwall of described cylinder assembly 1 comprises cylindrical shell and valve seat 11 two parts inwall, and this two parts inwall is smooth curved surface, and is coated with anticorrosive coat.The outer wall of cylinder assembly 1 is also coated with anticorrosive coat.The lateral wall of valve seat 11 is provided with the external screw thread 111 engaged, and device head 3 is provided with the internal thread 31 be bonded with each other with external screw thread 111.This novel dexterously convert engagement threads relation is set, overcoming with this existingly makes the inwall of valve seat 11 can not apply anticorrosive coat due to thread seal problem, namely the whole inner wall section of cylinder assembly 1 is coated with anticorrosive coat, guarantees cylinder body of fire extinguisher Corrosion Protection with this.
Preferably, described jet hose 2 comprises rubber tube 21 and a plastic nozzle, and this plastic nozzle comprises nozzle casing 22 and a playpipe 23.Nozzle casing 22 is provided with and lays respectively at this nozzle casing 22 its cover outer connector 221 of medial and lateral and interior connector 222, and this outer connector 221 and interior connector 222 inside are interconnected setting.Nozzle casing 22 is connected with rubber tube 21 by outer connector 221, and one end of playpipe 23 is connected to interior connector 222.On playpipe 23, the corresponding position circumference near its link is distributed with several internal gas pressure holes 230 (being positioned at nozzle casing 22), and on nozzle casing 22, circle distribution has several outer pressure holes 220 in corresponding several internal gas pressure holes 230 described.Provide internal gas pressure hole 230 and outer pressure hole 220 in specific embodiment and be respectively equipped with six, by fit in this inside and outside pressure hole structure, play the effect of balance nozzle ambient air pressure, strengthen jet performance.
