Hole, guide rod is penetrated to be slided in pilot hole, simple in structure, guiding stablize it is smooth, when pressure is excessive, flap along be oriented to slide
Dynamic structure slide-open, again along guiding slide construction sliding closing after pressure release so that system pressure maintains within limits.
Further, described guide rod one end is connected with flap, and being additionally provided with the other end prevents guide rod from guiding
The block deviate from hole, improves stability in use, avoids pressure from crossing the impact of senior general's flap and flies out, improves the safe to use of valve
Property.
Further, device is dismountable between the block and pilot hole and both ends abut against block and guiding
The anti-moving part of transport in hole, will be transported in the ice chest safety valve of conveyer belt safeguard structure anti-follower arrangement block and pilot hole it
Between so that flap is resisted against on valve port, so as to prevent that flap is movable, ensures the security reliability of transport.
Further, the block is the nut of device on the guide bar, and the anti-moving part of the transport is led to be sleeved on
To the pipe fitting on bar, the both ends of pipe fitting are resisted against on block and pilot hole, simple in structure, and handling are easy to use.
Further, the bottom of the valve body is provided with connecting flange, convenient and simple for connection, good airproof performance.
Further, the bottom surface of the connecting flange is additionally provided with sealing plate.
Compared with prior art, the utility model advantage is：
Ice chest safety valve described in the utility model with safeguard structure realizes sealing using the weight of flap itself, can
Long-acting to ensure constant Opening pressure, service life length, stability is good, meets the needs of normally producing, and maintains system pressure to exist
Within a certain range, so as to effectively achieve the purpose that protective device, pipeline and system safety.
