Abstract

The utility model provides an urgent release formula heat opens valve, which comprises the following components: a valve body, a valve cove, the valve clack, the rocker, valve gap and valve body fixed connection, set up the export of medium inlet and medium on the valve body, the valve clack articulates on the rocker end, the rocker root articulates on the valve body, the valve body outside is equipped with presses the valve clack device, but press the valve clack device to include split type handle and frit, the handle includes handle A and handle B, handle A and rocker fixed connection, turning handle A makes the valve clack reach the off -position, handle B insert in the shaft hole of handle A afterbody and with but the frit joint, but frit restriction rotate handle makes the valve clack valve keep at the off -position, but frit chance hot melt is separated. The beneficial effects of the utility model are that: when the conflagration not breaing out, but the frit is spacing each other with the handle for the valve clack keeps at the off -position, blocks the medium and flows, when the conflagration breaing out, but thermal dissolution is met to the frit, and the valve clack is opened under the effect of medium power, and the release medium supplies water rapidly.

Description

A kind of urgent release type heat opens valve

Art

This utility model is related to a kind of heat and opens valve, and more particularly to a kind of urgent release type heat opens valve.

Background technology

The valve of similar function is less in the market, does not supply water in time in fire-fighting domain Chang Yinwei and causes fire dangerous situation Become complicated.In prior art, in order that valve opens rapidly the pneumatic means generally using spring reset, when fire occurs When, the gas in cylinder is released and realizes spring reset, and under spring force, flap is opened, this complex structure, and is supplied Water is slow, does not far reach security against fire requirement.

The content of the invention

To overcome the drawbacks described above of existing fire valve, this utility model provides a kind of simple structure, supply water rapidly heat Open valve.

It is that a kind of urgent release type heat opens valve, including valve that this utility model solves the technical scheme of its technical problem employing Body, valve gap, flap, rocking bar, valve gap are fixedly connected with the valve body, and medium inlet and media outlet are arranged on valve body, and flap is hinged on On rocking bar end, rocking bar root is hinged on valve body, and pressure Valve clack device is provided with outside valve body, and pressure Valve clack device includes split type Handle and can frit, handle includes that handle A and handle B, handle A are fixedly connected with the rockers, and rotates handle A and flap is reached Off-position, handle B insertion handle A afterbodys axis hole in and with it is described can frit clamping, can frit limit handle rotate cause flap Off-position is maintained at, can the melting of frit heat.

The beneficial effects of the utility model are：When there is no fire, can frit it is mutually spacing with handle so that flap protect Hold in off-position, block media flow；Occur fire when, can frit heat dissolving, in the presence of medium power flap open, release Medium is put, it is rapid to supply water；Recover it is normal after close valve using handle, reinstalling can frit so that flap is continually maintained in Off-position.

Specific embodiment

As shown in Figure 1, 2, 3, a kind of urgent release type heat opens valve, including valve body 2, valve gap 1, flap 4, rocking bar 5, valve gap 1 It is fixedly connected with valve body 2, medium inlet 3 and media outlet 10 is set on valve body 2, flap 4 is hinged on 5 end of rocking bar, rocking bar 5 Root is hinged on valve body 2, is provided with pressure Valve clack device outside valve body 2, and pressure Valve clack device includes split type handle and fusible Block 6, handle include that handle A7 and handle B8, handle A7 are fixedly connected with rocking bar 5, rotate handle A7 and cause flap 4 to reach off-position, Handle B8 insertion handle A7 afterbodys axis hole 9 in and with it is described can 6 clamping of frit, can frit 6 limit handle rotate cause flap 4 Off-position is maintained at, can the melting of 6 heat of frit.

After valve is arranged on pipeline, flap 4 is in off-position, blocks flow of media, when fire condition is run into, can frit 6 Heat melts, and medium power is acted on flap 4, and flap is opened, and medium enters valve body by medium inlet 3, by media outlet 10 Flow out.

Claims (1)
