Abstract
The utility model provides an air film special pressure release of building and exhaust apparatus, including being used for the air guide piece of fixed mounting on the air film film body, the air guide piece is provided with the gland, the gland is connected with the casting die spring that sets up on the air guide piece. Air film special pressure release of building and exhaust apparatus can install it and use on the film body, rather than installing on other brick walls or rigidity structure. It can install additional as required at any time, tear open trade also very convenient. Also can select different capacity and aperture according to the size of discharge of fumes and gas during the alternative use. Effectively trade wind for the air film building, safe row presses and the accurate measurement air leakage provides effectual device.
Description
Technical field
The utility model relates to a kind of pneumatic membrane building device, especially relates to the special pressure release of a kind of pneumatic membrane buildingAnd exhaust apparatus.
Background technology
At present, China's pneumatic membrane building system does not also have building standard, in a lot of pneumatic membrane building projects all existPortion's ventilation volume is inadequate, and pressure relief capability does not have or the problem that pressure release is inadequate. Under such internal environment,The use of someone environment, just there will be, and personnel are uncomfortable in chest or supply the situation of unsaturated vapor dizziness to occur;The topmost aspect of another one is if the exhaust pressure discharge device of configure dedicated not, and pneumatic membrane building is in inflationThe danger that is easy in process pressure overload occurs and pneumatic membrane building explosive failure occurs.
Utility model content
The utility model provides the special pressure release of a kind of pneumatic membrane building and exhaust apparatus, has solved above askingTopic, its technical scheme is as described below:
A kind of special pressure release of pneumatic membrane building and exhaust apparatus, comprise for being fixedly mounted on air film film bodyAir-guide part, described air-guide part is provided with gland, described gland and the casting die spring phase being arranged on air-guide partConnect.
The top of described gland is provided with the space of restriction gland aperture.
Described air-guide part outer setting has neonychium lid, for fastening gland of used time not.
Described air-guide part is provided with through hole, is the reserving hole of placing sensor, and described sensor is used forMeasure external and internal pressure poor and perception gas flow and flow velocity, sensor is set if do not needed, this hole is closedState.
The special pressure release of described pneumatic membrane building and exhaust apparatus can be arranged on film body to be used, instead of mustMust be arranged on other brick walls or rigidity structure. It can install additional as required at any time, changes also non-Normal convenient. When choice for use, also can select different capabilities and aperture according to the size of capacity. For air filmBuilding is effectively changed wind, and safe row pressure and Measurement accuracy air leakage provide effective device.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the special pressure release of described pneumatic membrane building and exhaust apparatus comprise for fixing peaceBe contained in the air-guide part 1 on air film film body, described air-guide part 1 is provided with gland 3, described gland 3 with establishThe casting die spring 2 of putting on air-guide part 1 is connected, and described air-guide part outer setting has neonychium lid 4,Be used for not fastening gland 3 of used time.
The special pressure release of described pneumatic membrane building and exhaust apparatus can use ageing-resistant plastics or lightweight aluminium closesGold material is processed, and the upper casting die spring 2 of configuration. The elasticity of spring be according to pressure index design andProcessing, in the time of overpressure load, spring is opened gland 3 with regard to pressurized, has one at the top of glandThe space of restriction gland aperture, this restricted quarter both can limit capacity, and the gear snow of also can becalming is anti-Only rainwater pours in down a chimney.
The use state of the special pressure release of described pneumatic membrane building and exhaust apparatus shows as shown in Figure 3,4.
The center of described casting die spring is upright rod member, and the top of this rod member is a rubber packing, bottomFor spring collet, in the middle of rod member, be spring fastener, see Fig. 5 a, 5b, 5c, for the spring of different length is pressedPart, different capacities and different pressures are selected the casting die spring of different length.
In the time that pressure is greater than the elastic pressure of spring, will extrusion spring fastener, spring is tightened, as figure4 open the packing of spring fastener topmost, and the gas of pneumatic membrane building inside is by outward opening exhaust.In the time of internal and external pressure balance, spring reset, air bleeding valve reverts to Fig. 3 state.
When use, the connected mode of the special pressure release of pneumatic membrane building and exhaust apparatus and film body is to beat on film bodyGo out a circular hole, directly exhaust apparatus air-guide part 1 is inserted, then adopt the mode of spiral knob to screw, convenient and swift, quantity and position can increase as required or reduce, if do not need use only need byIt uses neonychium lid 4 to screw, safe ready, practicality and high efficiency.
In addition, if the gas of discharging need to be reclaimed or processes time, only need install connection additional in its outsideDevice and pipeline, can directed discharge and process like this.
Claims (4)
