Detailed Description
The utility model will be further described with reference to the accompanying drawings in which:
the first embodiment is as follows:
as shown in fig. 1 to 4, the solid-liquid self-gravity constant pressure valve comprises a hollow gravity kettle 2, a plurality of slide rods 7 are arranged at the bottom of the gravity kettle 2, in the embodiment, the number of the slide rods 7 is four, the slide rods 7 are slidably connected with a slide rod support 6, a support base 5 matched with the gravity kettle 2 is arranged at the top of the slide rod support 6, a sealing ring 4 is arranged between the support base 5 and the gravity kettle 2, the sealing ring 4 is a soft polytetrafluoroethylene sealing ring, a feed inlet 1 is arranged on the gravity kettle 2, liquid or powdery solid can be added into the gravity kettle 2 through the feed inlet 1, so that the weight of the gravity kettle 2 is increased, and the sealing pressure is adjusted.
As shown in fig. 5, the gravity kettle 2 is provided with a discharge opening 9 at the bottom, and the liquid or powdery solid material in the gravity kettle 2 can be easily discharged through the discharge opening 9.
Example two:
the support base 5 is of an annular structure, the pressing plate 3 is arranged at the bottom of the gravity kettle 2, an annular groove matched with the pressing plate 3 is formed in the support base 5, the sealing ring 4 is installed in the annular groove, the pulley base is arranged on the sliding rod 7, the pulley base is rotatably connected with the pulley 8, the sliding rod 7 is slidably connected with the sliding rod support 6 through the pulley 8, and the rest is the same as the embodiment I.
In order to ensure the sliding effect of the sliding rod 7, the number of the pulleys 8 on the sliding rod 7 is not less than two, the sliding rod 7 can drive the gravity kettle 2 to move up and down along the sliding rod support 6, and when the gravity kettle 2 descends to the lowest end along with the sliding rod 7, namely the gravity kettle 2 is in a sealing state, the pressure plate 3 on the gravity kettle 2 is sunk into the annular groove and is tightly matched with the sealing ring 4, so that the secondary sealing effect is achieved.
