Abstract
The utility model discloses a diaphragm valve which belongs to the technical field of valve body design and manufacture. The diaphragm valve comprises a valve body (1) and a valve cap that is hermetically connected with the valve body (1), wherein a diaphragm (7) is arranged between the valve body (1) and the valve cap (2); the two ends of the diaphragm (7) are linear; and a middle section of the diaphragm (7) is a cambered rubber diaphragm. The diaphragm valve solves the technical problem that the diaphragm of the diaphragm valve cracks easily.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of membrane valve.
Background technique
The barrier film of existing membrane valve all is flat, and in valve closing and the process opened, barrier film is easy to deformation fracture, and working life is short, and the valve rod of existing membrane valve and valve body be connected as a single entity, maintenance and change all inconvenient.
Summary of the invention
For this reason, technical problem to be solved in the utility model is that the barrier film of membrane valve breaks easily, and then provides that a kind of barrier film is not easy to break, the service-strong membrane valve.
For solving the problems of the technologies described above, the utility model discloses a kind of membrane valve, and it comprises valve body, with the valve gap that described valve seal is connected, is provided with barrier film between described valve body and the described valve gap, and described barrier film is that two ends are lineal shape, and intermediate section is the diaphragm of rubber of arc.
The upper end of described valve gap is provided with the knob of the described membrane valve flow of control, and described knob is threaded with described valve gap; The inside of described valve gap is provided with the pushing block that is fitted and connected on described barrier film, is provided with valve rod between described pushing block and described knob.
Be provided with Returnning spring between described knob and the described valve rod.
Described knob and described valve rod are provided with blind hole at its junction surface respectively, and described Returnning spring is arranged in the described blind hole.
Technique scheme of the present utility model has the following advantages compared to existing technology:
Barrier film in the membrane valve of the present utility model is that two ends are lineal shape, and intermediate section is the diaphragm of rubber of arc, the distortion that it can have certain space, the working life of having improved barrier film; And, being flexibly connected between valve rod and the described valve gap, its installation and maintenance are convenient.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model, wherein according to specific embodiment of the utility model also by reference to the accompanying drawings
Fig. 1 is the structural representation of membrane valve of the present utility model.
Reference character is expressed as among the figure:
The 1-valve body, 2-valve gap, 3-knob, 4-Returnning spring, 5-valve rod, 6-pushing block, 7-barrier film.
Embodiment
Be illustrated in figure 1 as membrane valve of the present utility model, it comprises valve body 1, valve gap 2 and the knob 3 of controlling described membrane valve flow.Wherein, described valve body 1 is tightly connected with described valve gap 2, and described knob 3 is threaded with described valve gap 2; Be provided with barrier film 7 between described valve body 1 and the described valve gap 2, described barrier film 7 two ends are lineal shape, and intermediate section is the diaphragm of rubber of arc.
The inside of described valve gap 2 is provided with the pushing block 6 that is fitted and connected on described barrier film 7, is provided with valve rod 5 between described pushing block 6 and described knob 3.Described knob 3 is flexibly connected with described valve rod 5, and it is provided with the blind hole of placing Returnning spring 4 at its junction surface respectively.By rotation knob 3, promote described valve rod 5 and move up and down, and then the pushing block 6 that drive is attached thereto moves the distortion of control barrier film 7, the final flow of controlling by membrane valve.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the invention.
