Abstract
The utility model relates to a diaphragm valve, and belongs to the technical field of valves. The diaphragm valve comprises a diaphragm, a valve body and a valve bonnet, the valve bonnet is arranged on the valve body, and the diaphragm is placed between the valve body and the valve bonnet. The diaphragm valve is characterized in that a groove is arranged on a flange surface, which is connected with the valve bonnet, of the valve body, and a flange is disposed on the valve bonnet and is matched with the groove. The diaphragm valve has the advantages that the peripheral edge of the diaphragm is placed between the valve bonnet and the valve body, so that the peripheral edge of the diaphragm is completely isolated from the outside, the possibility that a fire source contacts with the flammable diaphragm is stopped thoroughly, requirements on sealing are met, the diaphragm valve is prevented from being burnt down, safety use of the valve is guaranteed, and whether the diaphragm is damaged or not can be monitored in real time through a drainage hole.
Description
Technical field
The utility model relates to valve technology field, especially relates to a kind of membrane valve.
Background technique
Membrane valve is mainly used in the pipe-line system of carrying Korrosionsmedium, and its working principle is to utilize rubber or plastic diaphragm that the driver part of medium and valve is isolated, and the driver part that prevents valve receives the corrosion of medium, the just use of assurance valve.
Because the self-characteristic of membrane valve, the easy damage rupture of long-time improper use barrier film pad can't visual discovery directly perceived after the damage.Though according to using regulation will regularly open and inspect the barrier film pad, the damage that how in the inspection phase, can monitor the barrier film pad in real time still is a blind area so far.The barrier film periphery of membrane valve is by valve gap it to be pressed abd fixed on the flanged surface of valve body in addition, so the outer side surface of barrier film Zhou Jun is exposed to the external world.In case the place breaking out of fire at membrane valve place, big fire will be roasted the barrier film exposed parts, makes its damage and loses due function, and flare is located to scurry in the valve from the crack of valve body and valve gap, finally is directed at valve leak.
The model utility content
The utility model is to provide a kind of membrane valve for solving the problems of the technologies described above.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of membrane valve; Comprise barrier film, valve body and valve gap; On said valve body, be provided with valve gap, said barrier film places between said valve body and the said valve gap, it is characterized in that: on said valve body and said valve gap flange connecting card, be provided with a groove; On said valve gap, be provided with a flange, said flange and said groove are complementary.
Top at said valve gap also is provided with a discharge orifice.
In said groove, also be provided with the fire prevention packing ring.
The beneficial effect of the utility model; The barrier film edge placed be arranged between valve gap and the valve body; The barrier film periphery is not contacted with the external world fully, thoroughly stopped the approach that burning things which may cause a fire disaster contacts with inflammable barrier film, not only reach seal request but also prevented its burning damage; Guarantee the safe handling of valve, can monitor barrier film in real time through discharge orifice simultaneously and whether damage.
Description of drawings
Fig. 1 is the utility model: a kind of membrane valve structural representation;
Fig. 2 is a K portion enlarged view among Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
With reference to shown in Figure 1, a kind of membrane valve comprises barrier film 3, valve body 1 and valve gap 2; On valve body 1, be provided with valve gap 2, barrier film 3 places between valve body 1 and the valve gap 2, on valve body 1 and valve gap 2 flange connecting cards, is provided with a groove 5; On valve gap 2, be provided with a flange 6; Flange 6 is complementary with groove 5, in groove 5, also is provided with fire prevention packing ring 7, also is provided with a discharge orifice 4 at the top of valve gap 2.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
