The first passage outside body, the side wall of first valve body are provided with the second passage, when second valve body drives described the
When two valve heads are with the described first sealing valve head depressurization, second passage turns on above-mentioned chamber and the second sealing valve head institute
In chamber.By said structure, make releasing pressure automatically and manual pressure release each control corresponding to valve port, so as to reduce manual pressure release
External force requirement, facilitates manual pressure discharge operations.
In above-mentioned exhaust pressure relief valve, first valve body stretches out the partial threads connection regulation spiral shell of the case top
Cap.By rotating regulating nut, so as to adjust the expanding force of the first spring on the first valve body, realize to the first sealing valve head and valve
Sealing regulation between plate valve mouth.In addition, the structure can also realize that emergency pressure relief operates.
In above-mentioned exhaust pressure relief valve, the case top snapping protective cover.Protective cover is set, prevented to the second valve body
Hand push button maloperation.
In above-mentioned exhaust pressure relief valve, the case top sets seal, institute for the hole position that first valve body stretches
State one section of set in the second valve body above the second spring be equipped with first valve body formed flexible sealing coordinate it is close
Sealing.By setting seal, the security of exhaust apparatus pressure release exhaust is improved.

Embodiment
As shown in figure 1, the exhaust pressure relief valve includes housing 1, from pressure release part, manual pressure release part, wrapped from pressure release part
Include the first valve body 3 of the first spring 4 and end with the first sealing valve head 301, manual pressure release part includes second spring 6, the
Two valve bodies 5, second seal valve head 501.The expansion fit of first valve body 3 is flexible for the first valve body 3 in the top of housing 1, the top of housing 1
Hole position set seal.Integrated in housing 1 close to top and be provided with the valve plate 101 with valve port, the first spring of overcoat of the first valve body 3
4, the tensioner of the first spring 4 is limited between the inner top of housing 1 and the first sealing valve head 301, and the first sealing valve head 301 is first
The lower sealing valve port with valve plate 101 of the effect of spring 4.The overcoat second spring 6 of second valve body 5, it is in stretch that both, which are placed in the first valve body 3,
Contracting coordinates, and second spring 6 is limited between the first valve body 3 and the second valve body 5, and the one end of the second valve body 5 is under the effect of second spring 6
Stretch out the top of the first valve body 3 and be used as hand push button, the other end of the second valve body 5 stretches out the first sealing valve head 301 of the first valve body 3
And the second sealing valve head 501 is fixedly connected with, the second sealing valve head 501 seals valve head 301 under the effect of second spring 6 with first
