Description
Technical field
This utility model belongs to vacuum drainage field, particularly relates to a kind of negative-pressure type pneumatic diaphragm valve and adopts the low-pressure drainage system of this diaphragm valve.
Background technology
Being usually used in the pneumatic diaphragm valve in vacuum wastewater and sewage collection system on market can only rely on malleation to drive or motorized motions, adopts this kind of type of drive to need to set up extra driving mechanism within the system, thus the raising of production cost can be caused. Additionally, pneumatic diaphragm valve is at a kind of valve common in modern industry at present. This type of valve is mainly by pneumatic actuator, barrier film and valve body three part composition, and therefore it exists the problems such as inner body is more, structure is complicated, sealing is poor.
In consideration of it, how to design a simple in construction, and the pneumatic diaphragm valve being applicable to low-pressure drainage system has become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Utility model content
For overcoming the problems referred to above, this utility model provides a kind of negative-pressure type pneumatic diaphragm valve on the one hand, solves existing Pneumatic diaphragm valve structure complicated, the problem that cost is high.
On the other hand, this utility model provides a kind of low-pressure drainage system adopting above-mentioned pneumatic diaphragm valve, and the pneumatic diaphragm valve in this vacuum system utilizes the negative pressure of system itself to drive, because without additional driving mechanism, reducing production cost.
This utility model solves its technical problem and be the technical scheme is that a kind of negative-pressure type pneumatic diaphragm valve, including base, this base is provided with the left opening and right opening that communicate with inside it, also include being placed in base and left opening and the barrier film of right opening can being cut off, this diaphragm is provided with the valve gap fixed with base by bolt, and the upper surface of this valve gap is further opened with the upper shed being connected with vacuum system. During work, upper shed connects formation vacuum with vacuum system, and then drives barrier film to move upward, it is achieved communicating of left opening and right opening.
For ensureing that barrier film operationally has sufficiently large space motion, the upper end inner surface of described valve gap is circular arc, and this structure still prevents barrier film and blocking occurs.
As further improvement of the utility model, upper shed and barrier film are arranged concentrically, and then ensure the uniform of barrier film stress.
As a kind of this theme of low-pressure drainage system, it includes above-mentioned negative-pressure type pneumatic diaphragm valve, also include the water inlet pipe being connected with left opening, the vacuum drainpipe being connected with right opening, and one end is connected with upper shed, the other end connects with vacuum drainpipe takes trachea. Taking the electromagnetic valve being also equiped with on trachea for controlling to take trachea gas path on-off. When electromagnetic valve is opened, the epicoele of diaphragm connects formation vacuum with vacuum drainpipe, and barrier film is jack-up upwards so that left opening and right opening communicate with each other, and is evacuated in the vacuum drainpipe of right side by the sewage of left side water inlet pipe by means of the suction of vacuum simultaneously. After electromagnetic valve power-off, logical air is to the epicoele of diaphragm, and diaphragm valve is closed, and completes a blowdown process.
The beneficial effects of the utility model: in this utility model, pneumatic diaphragm valve utilizes the negative pressure of vacuum system to drive the work of valve inner septum, greatly simplify the internal structure of pneumatic diaphragm valve, reduces manufacturing cost. Additionally, arrange in circular arc by the upper end inner surface of valve gap, it is ensured that the jack-up space of barrier film, effectively prevent the generation of barrier film clogging simultaneously. In this utility model, low-pressure drainage system has simple in construction, it is not necessary to set up the feature of extra driving mechanism, meets the energy saving requirement of actual production, life.
Below with reference to drawings and Examples, this utility model is described in detail.

Detailed description of the invention
Embodiment 1,
Seeing also Fig. 1 to 2, a kind of negative-pressure type pneumatic diaphragm valve 101, including base 1, barrier film 2 and valve gap 3.
Wherein, base 1 is provided with the left opening 4 and right opening 5 that communicate with inside it. Barrier film 2 is placed in base 1, and can cut off left opening 4 and right opening 5. At the valve gap 3 being provided above being fixed by bolt 6 with base 1 of barrier film 2, the upper surface of this valve gap 3 is further opened with the upper shed 7 being connected with vacuum system. Preferably, the upper end inner surface of valve gap 3 is circular arc, and upper shed 7 and barrier film 2 are arranged concentrically.
During work, upper shed connects formation vacuum with vacuum system, and then drives barrier film upwards jack-up, it is achieved communicating of left opening and right opening.
Embodiment 2,
Referring to Fig. 3, a kind of low-pressure drainage system, it includes negative-pressure type pneumatic diaphragm valve 101 as described in Example 1.
