Abstract
The invention discloses an extinguisher valve, which comprises a lower valve body 2, wherein the upper part of the lower valve body 2 is provided with an upper valve body 7 which is provided with a positioning pin 8 configured with a safety pin 9; one end of the positioning pin 8 is connected with a manual level 10; the other end of the positioning pin 8 is provided with one end of a spring 6 arranged in an inner cavity 11 formed by the upper valve body 7 and the lower valve body 3; the other end of the spring 6 is connected with a puncturing needle 5; the lower end of the puncturing needle 5and the inside of the inner cavity 11 are provided with a sealing membrane 4; when the safety 9 is removed, the manual level 10 can be handled to drive the positioning pin 8 to move right; the puncturing needle 5 is released to move downward quickly under the pre-action of the spring 6 to puncture the sealing membrane 4 to release extinguishing agent. The extinguisher valve has the characteristicsof high safety, simple maintenance, convenient use and effective prevention the leakage of the extinguishing agent.
Description
Technical field
The invention belongs to the fire-fighting equipment technical field, be specifically related to a kind of 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 invention provides a kind of safe, extinguisher valve of safeguarding employing seal membrane simple, easy to use, can effectively prevent the characteristics that extinguishing chemical leaks.
To achieve these goals, the technical solution used in the present invention is: a kind of 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 present invention 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 invention.
The specific embodiment
With reference to the accompanying drawings structural principle of the present invention and operation principle are described in further detail.
Referring to Fig. 1, a kind of 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 invention 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.
