Abstract
The utility model relates to a diaphragm seal fire extinguisher valve which comprises a lower valve body 2, wherein an upper valve body 7 is arranged on the upper part of the lower valve body 2, a positioning pin 8 is arranged on the upper valve body 7 and is provided with a safety pin 9, one end of the positioning pin 8 is connected with a hand lever 10, and the other end of the positioning pin 8 is connected with one end of a spring 6 in an inner cavity formed by the upper valve body 7 and the lower valve body 2; a piercing needle 5 is connected to the other end of the spring 6, and seal diaphragms 4 are respectively arranged on the lower part of the piercing needle 5 and in the inner cavity 11; and the purpose of releasing extinguishing agents can be achieved by plucking the safety pin 9, removing a hand lever 10 to drive the positioning pin 8 to move rightwards and releasing and causing the piercing needle 5 acted by the preact force of the spring 6 to downwards and fast move to pierce the seal diaphragms 4. The utility model has the advantages of high safety, easy maintenance, convenient use and effective control of the leakage of the extinguishing agents.
Description
Technical field
The utility model belongs to the fire-fighting equipment technical field, is specifically related to a kind of diaphragm seal formula extinguisher valve.
Background technology
Extinguisher valve is the important composition parts of fire extinguisher, form by valve body, spool, valve rod, pressure handle and carrying handle etc., valve rod is installed in the valve body, pressure handle is fixed on the valve body with bearing pin, have the insurance pin-and-hole on the pressure handle, carrying handle is fixed on the valve body with bearing pin, at present, extinguisher valve generally adopts spring guiding and container self air pressure push-tight spool to contact with sealing surface and seals, but, on generation vibration and place of jolting such as naval vessel, be easy to generate spool and depart from, thereby cause extinguishing chemical to leak, so that influence the serviceability of fire extinguisher.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provide a kind of safe, safeguard diaphragm seal formula extinguisher valve simple, easy to use, can effectively prevent the characteristics that extinguishing chemical leaks.
To achieve these goals, the technical solution adopted in the utility model is: a kind of diaphragm seal formula extinguisher valve, comprise valve body 2, be provided with upper valve body 7 on following valve body 2 tops, upper body valve 7 is provided with alignment pin 8, is furnished with safety pin 9 on the alignment pin 8, one end of alignment pin 8 connects hand lever 10, the other end is connected with a end of spring 6 in being arranged on upper valve body 7 and inner chamber 11 that following valve body 2 is formed, be connected with on the other end of spring 6 and puncture pin 5, in the bottom that punctures pin 5, inner chamber 11, be provided with seal membrane 4.
Bottom at following valve body 2 also is provided with filling valve 3.
Said seal membrane 4 is threaded with upper valve body 2.
Because the utility model adopts seal membrane to seal preact that extinguishing chemical, lever principle start retracting spring up for safekeeping and tries hard to recommend and puncture the acupuncture envelope diaphragm of decoding, discharge extinguishing chemical, so have safe, safeguard simply, easy to use, and can effectively prevent the characteristics that extinguishing chemical leaks.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to the accompanying drawings structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, a kind of diaphragm seal formula extinguisher valve, comprise valve body 2, be provided with upper valve body 7 on following valve body 2 tops, upper body valve 7 is provided with alignment pin 8, is furnished with safety pin 9 on the alignment pin 8, one end of alignment pin 8 connects hand lever 10, the other end is connected with a end of spring 6 in being arranged on upper valve body 7 and inner chamber 11 that following valve body 2 is formed, is connected with on the other end of spring 6 and punctures pin 5, is provided with seal membrane 4 in the bottom that punctures pin 5, inner chamber 11.Bottom at following valve body 2 also is provided with filling valve 3.The bottom of following valve body 2 siphon component 1 that also has been threaded.Siphon component 1, filling valve 3, upper valve body 7 all are connected by thread seal with following valve body 2, and seal membrane 4 compresses diaphragm with upper valve body 2 by being threaded and seals extinguishing chemical up for safekeeping.
Operation principle of the present utility model is:
When breaking out of fire, pull out safety pin 9 earlier, outwards move hand lever 10 then rapidly, hand lever 10 drives alignment pin 8 and moves right, thereby release punctures pin 5 makes its downward rapid movement under the elasticity preact power effect of spring 6 puncture seal membrane 4, thereby extinguisher valve is opened, in the container extinguishing chemical flow into down valve body 2 by siphon component 1 after down the outlet of valve body 2 discharge.
Filling valve 3 is the assemblies that are used for the can extinguishing chemical.
