Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, it is provided that the vertical storm valve of self-action that a kind of structure is simpler.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of vertical storm valve of self-action, there is valve body, valve gap, there is in valve body valve seat, water stream channel, and the valve pocket being made up of valve body and valve gap, valve seat is additionally provided with locating shaft, it is characterized in that, the arm of force being mutually connected to each other and lever it is provided with in described valve body, one end of described lever is hinged with described locating shaft, the described arm of force is provided with sealing gasket, described sealing gasket is located close to the position of water stream channel, lever is located close to the position of valve pocket, described lever is provided with balancing weight, when there is no current in water stream channel, the gravity relying on balancing weight makes to be close between sealing gasket and valve seat sealing.
Preferably, being also associated with spring between the inwall top of described lever and valve gap, when not having current in water stream channel, the active force of lever is made to seal between sealing gasket and valve seat by described spring.
Preferably, being also associated with spring between the inwall sidepiece of the described arm of force and valve gap, when not having current in water stream channel, the active force of the arm of force is made to seal between sealing gasket and valve seat by described spring.
This utility model has the advantages that
Compare traditional storm valve, good backflow effect can be played, also simplify structure simultaneously, reduce production and use cost.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model is not limited solely to embodiment.
Shown in Fig. 1, Fig. 2, a kind of vertical storm valve of self-action, has valve body 1, valve gap 11, has valve seat 2, water stream channel 9 and the valve pocket 10 being made up of valve body 1 and valve gap 11 in valve body 1, being additionally provided with locating shaft 7 on valve seat 2, locating shaft 7 is physically located in valve pocket 10.Being provided with the arm of force 3 and lever 4 that are mutually connected to each other in valve body 1, one end of lever 4 is hinged with locating shaft 7, and lever 4 can rotate centered by locating shaft 7.Being provided with sealing gasket 6 on the arm of force 3, sealing gasket 6 is arranged on the arm of force 3 surface by assemblies such as bolts.Sealing gasket 6 is located close to the position of water stream channel 9, and lever 4 is located close to the position of valve pocket 10, and lever 4 is provided with balancing weight 5, and balancing weight 5 is arranged on lever 4 by bolt 8.When not having current in water stream channel 9, relying on the gravity of balancing weight 5 to make to be close to sealing between sealing gasket 6 and valve seat 2, make water stream channel 9 closed center, current up can not reflux from little.Working as water drain, sewage, from the top of water stream channel 9 toward dirty, relies on the impulsive force of water, and sealing gasket 6 and valve seat 2 depart from, and the arm of force 3 and lever 4 all rotate counterclockwise；After sewage discharge, relying on the gravity of balancing weight 5, the arm of force 3 and lever 4 rotate clockwise, until being close to sealing between sealing gasket 6 and valve seat 2.
Shown in Fig. 3, for embodiment 2 of the present utility model, it is also associated with spring 12 between the inwall top of lever 4 and valve gap 11, when there is no current in water stream channel 9, the active force of lever 4 is made to seal between sealing gasket 6 and valve seat 2 by described spring 12, and namely now lever 4 is applied downward active force by spring 12.When sewer, lever 4 rotates and makes spring 12 be compressed, and discharges complete rear spring 12 and discharges downwards so that between sealing gasket 6 and valve seat 2, the moment is held against sealing.
Shown in Fig. 4, for embodiment 4 of the present utility model, it is connected to spring 12 between the inwall sidepiece of the arm of force 3 and valve gap 11, when there is no current in water stream channel 9, the active force of the arm of force 3 is made to seal between sealing gasket 6 and valve seat 2 by described spring 12, and namely now the arm of force 3 is applied active force upwards by spring 12.When sewer, the arm of force 3 rotates and makes spring 12 be compressed, and discharges complete rear spring 12 and upwards discharges so that between sealing gasket 6 and valve seat 2, the moment is held against sealing.
Last it is noted that above example only in order to this utility model is described and and technical scheme described by unrestricted this utility model, therefore, although this utility model is had been carried out describing in detail by this specification with reference to each above-mentioned embodiment, but, it will be understood by those within the art that, still this utility model can be modified or equivalent replacement, and all are without departing from the technical scheme of spirit and scope of the present utility model and improvement thereof, it all should be encompassed in right of the present utility model.
