Abstract
The utility model provides a knobby suction valve and relates to the filed of bidirectional plunger pump accessories. The knobby suction valve comprises a first valve body and a second valve body, wherein the first valve body is connected with the second valve body in series. An O-shaped stop ring, a spring, a sealing bead and an alloy valve seat are arranged on each of the first valve body and the second valve body, the spring is arranged between the O-shaped stop ring and one end of the sealing bead, and the other end of the sealing bead is matched with the alloy valve seat. When the knobby suction valve works in material lifting stage, liquid flow pressure overcomes spring strength to push the sealing bead fully open and liquid is sucked. After a direction is changed, the sealing bead is pressed by the spring strength and sealing speed is accelerated. The knobby suction valve is used and a plurality of similar ball valve sealing systems are used in series so as to further improve sealing speed of the ball valve sealing systems and effectively solve the problem of suction material reflux caused by slow sealing speed when high viscosity suction materials are used. Meanwhile, the problem of difficult suction caused by the suction material reflux is solved, and working efficiency of a pump is improved.
Description
Technical field:
The utility model relates to two-way function plunger pump fitting field, is specifically related to be used for the more piece suction valve on the two-way function plunger pump.
Background technique:
Plunger pump is an important device of hydraulic system.Its relies on plunger to-and-fro motion in cylinder body, the volume of seal operation cavity volume is changed realize oil suction, presses oil.Plunger pump has advantages such as rated pressure height, compact structure, efficient height and Flow-rate adjustment convenience, is widely used in the occasion that high pressure, big flow and flow need be regulated, in hydraulic press, engineering machinery and boats and ships.Therefore traditional suction valve all adopts single-unit, all can't well suck the pump housing to what high viscosity liquid material such as full-bodied butter class, building putties, polyurethane, latex paint used self-priming mode, causes the pump can not omnidistance effectively work, causes unloaded phenomenon.In case wearing and tearing occur, will influence pump efficiency, lower the life-span of pump.
The model utility content:
The purpose of the utility model provides a kind of more piece suction valve, and it efficiently solves the phenomenon that the use high viscosity sucks the suction material backflow that sealing causes slowly when expecting, the while has also solved the problem of the absorption difficulty that sucking expects to flow backwards causes, the working efficiency of raising pump.
In order to solve the existing problem of background technique, the utility model is to adopt following technological scheme: it comprises first valve body 1, second valve body, 2, the first valve bodies 1 seal with second valve body 2 and are in series.
Described first valve body 1 and second valve body 2 are by O type back-up ring 1-1, spring 1-2, sealant beads 1-3, alloy valve seat 1-4; Be provided with spring 1-2 between the end of O type back-up ring 1-1 and sealant beads 1-3, the other end of sealant beads 1-3 and alloy valve seat 1-4 are sealed and matched.
During the utility model work, carry the material stage, flow stream pressure overcomes spring force and backs down sealant beads 3, and liquid is sucked, and after the switching-over, pushes down sealant beads 3 by spring force, accelerates sealing speed, and sealant beads 3 and alloy valve seat 4 are closely cooperated.Re-use the more piece suction valve, the ball valve sealing system series connection that several covers are similar is used, and further improves ball valve system sealing speed.
The utlity model has following beneficial effect: efficiently solve the phenomenon that the use high viscosity sucks the suction material backflow that sealing causes slowly when expecting, the while has also solved the problem of the absorption difficulty that sucking expects to flow backwards causes, the working efficiency of raising pump.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technological scheme: it comprises first valve body 1, second valve body, 2, the first valve bodies 1 and 2 sealings of second valve body and is in series.
Described first valve body 1 and second valve body 2 are by O type back-up ring 1-1, spring 1-2, sealant beads 1-3, alloy valve seat 1-4; Be provided with spring 1-2 between the end of O type back-up ring 1-1 and sealant beads 1-3, the other end of sealant beads 1-3 and alloy valve seat 1-4 are sealed and matched.
During the work of this embodiment, carry the material stage, flow stream pressure overcomes spring force and backs down sealant beads 3, and liquid is sucked, and after the switching-over, pushes down sealant beads 3 by spring force, accelerates sealing speed, and sealant beads 3 and alloy valve seat 4 are closely cooperated.Re-use the more piece suction valve, the ball valve sealing system series connection that several covers are similar is used, and further improves ball valve system sealing speed.
This embodiment efficiently solves the phenomenon that the use high viscosity sucks the suction material backflow that sealing causes slowly when expecting, the while has also solved the problem of the absorption difficulty that sucking expects to flow backwards causes, the working efficiency of raising pump.
