Abstract
The utility model relates to a pressure-relief explosion-proof valve which is matched with an atmosphere pressure heating stove to be used. The pressure-relief explosion-proof valve is composed of an upper cover and a lower body to form a cavity which is divided into a top cavity and a bottom cavity by a seal ring holder, a sealing ring and a round clamp and is supported by a spring support installed in the top cavity. So the pressure-relief explosion-proof valve is made.
Description
Technical field
The utility model discloses a kind of and the matching used release explosion-proof valve of normal pressure air heating stove, belong to the daily living article technical field.
Background technique
The release explosion-proof valve is the indispensable parts of normal pressure air heating stove, is used to prevent boiler just in case the blast that builds the pressure.At present, on the market existing release explosion-proof valve be can only disposable release.
Summary of the invention
The purpose of this utility model provides a kind of with the spring pressure control, with round clamp and seal ring sealing, and under the situation of not changing parts, repeatedly the explosion-proof valve of release is promptly convenient again safely.
The purpose of this utility model is achieved in that it includes loam cake and lower body, and described loam cake and lower body are formed a main body.It is fixed with nut by screw rod and is in the same place, form unimpeded cavity up and down, by packing holder and seal ring and round pressing plate cavity is divided into two cavitys up and down, spring is contained in the upper plenum, by lower support on loam cake and the packing holder, seal ring is played a role, on be covered with pressure relief vent and be used for release.
Described spring upper-end surface is provided with round pressing plate, and the top of described loam cake is provided with a hole and screw mandrel, can be used for regulating the pressure that explosion-proof valve need bear.
The immovable point of described loam cake and lower body has 2～4.
Described pressure relief vent has 2～4.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is a sectional structure schematic representation of the present utility model.
Embodiment
As shown in Figure 3: the release explosion-proof valve is formed a main body by loam cake 1 and lower body 8, be fixed with nut 4 by screw rod 3 and be in the same place, form unimpeded cavity 7 up and down, by packing holder 6 and seal ring 5 and round clamp 9 cavity 7 is divided into two cavitys up and down again, spring 2 is contained in the upper plenum, by lower support on loam cake 1 and the packing holder 6, make seal ring 5 its seal actions of performance.Loam cake 1 is provided with pressure relief vent 10 and is used for release (as shown in Figure 1), makes the release explosion-proof valve like this.It is characterized in that: because seal ring 5 and round clamp 9 and spring 2 are independently movable body, so repeatedly release and not damaging, this release explosion-proof valve is installed on the body of heater, when boiler builds the pressure, pressure will be propped up spring 2 by the cavity 7 of explosion-proof valve, form automatic pressure-relieving, auto-closing again after the release can be removed the trouble of changing parts from.
