Abstract
The utility model discloses a diaphragm deluge valve which is convenient in installation and reliable in sealing. The diaphragm deluge valve comprises a valve body and a valve cover, wherein the valve cover is arranged on the valve body, a sealing diaphragm is arranged in the valve body, a circular-arc bulge is arranged at the contacted part of the sealing diaphragm and the valve body, and circular-arc bulges are also arranged at the contacted part of the sealing diaphragm and the valve cover. The diaphragm deluge valve is applicable to fire-fighting systems.
Description
Technical field
The utility model relates to a kind of fire-protection equipment, relates in particular to a kind of barrier film drench valve that is used on the fire-fighting system.
Background technique
When fire alarm takes place in the zone of protection; by the fire alarm Fire extinguisher; directly open the solenoid valve of barrier film drench valve; the water of pressure chamber is discharged fast; because pressure chamber pressure release; thereby the hydraulic pressure that acts on the seal membrane bottom boosts seal membrane rapidly; thereby make current enter active chamber; flow to whole pipe network sprinkling fire; a part of pressure flow is to the warning pipe network simultaneously; making warning water system send the tinkle of bells reports to the police; the pressure switch action sends the signal indication or directly start fire service pump water supply to night shift room, thereby the barrier film drench valve is played important effect in fire-fighting system.And there is the installation requirement height in the seal membrane in the barrier film drench valve, is easy to generate deficiencies such as seepage.
The model utility content
The technical problems to be solved in the utility model provides a kind of easy for installation, reliable sealing barrier film drench valve.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises valve body, is located at the valve gap on the valve body, is provided with seal membrane in the described valve body, and described seal membrane and valve body contacting point are provided with the circular arc projection, and described seal membrane and valve gap contacting point also are provided with the circular arc projection.
The utility model compared with prior art has following obvious advantage and beneficial effect:
1, easy for installation.Because the seal membrane in the utility model is provided with the circular arc projection,, can influence sealing effect yet, thereby make easy for installation even seal membrane produces deflection during assembling.
2, sealing is reliable.Because the seal membrane in the utility model is provided with the circular arc projection, has guaranteed the excellent sealing with valve body, valve gap, thereby effectively improved operational reliability.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: the utility model comprises valve body 1, and valve body 1 is provided with valve gap 2, is provided with seal membrane 3 in the valve body 1, and seal membrane 3 is provided with circular arc projection 5 with valve body 1 contacting point, is provided with circular arc projection 6,7 with valve gap 2 contacting points.Owing to setting up of circular arc projection on the seal membrane, not only reduced the technical requirements of assembling, and guaranteed and the excellent sealing of valve body, valve gap, effectively improved operational reliability.
