Abstract
The invention provides a vertical type one-way combination valve for a reciprocating type gas-liquid two-phase mixture conveying pump, which mainly comprises a valve body, a valve inlet, a valve outlet, an inlet chamber and an outlet chamber, wherein the valve outlet is arranged at an inner ring of the valve body, the valve inlet is arranged at an outer ring of the valve body, a valve ring is arranged in the inlet chamber, a through hole is arranged in the valve body between the inlet chamber and the outlet chamber, and the valve outlet is provided with a valve plate. In the vertical type one-way combination valve for the reciprocating type gas-liquid two-phase mixture conveying pump, as the valve outlet is arranged at the inner ring of the valve body, and the valve inlet is arranged at the outer ring of the valve body, the flow path area of the valve inlet is increased, and the flow rate of a medium at the valve inlet is decreased, so that energy waste can be reduced, and the suction performance of the pump can be improved; and meanwhile, as a flow dividing hole is arranged in the valve body between the inlet chamber and the outlet chamber, a double-flow path structure is realized, and the flow rate of the medium at the valve inlet is further decreased, so that the opening height of the valve ring can be reduced, a lag angle of closing the valve ring can be reduced, and the pressure loss and the energy waste can be reduced.
Description
Technical field
The present invention relates to the reciprocating pump combination brake switch and proporting, especially a kind of reciprocating type gas-liquid two-phase mixes defeated pump with vertical unidirectional combination brake switch and proporting.
Background technique
Reciprocating pump is an indispensable series products in the industrial pump, and its performance does not change with the change of head pressure and fed sheet of a media viscosity.Its active chamber is isolated from the outside by seal arrangement, to-and-fro motion in fluid cylinder makes working chamber volume produce cyclically-varying by piston, utilizing pump valve (suction valve, expulsion valve) and pipeline connection or closure to inhale, arrange medium, is a kind of very important fluid machinery.Its employed suction valve, expulsion valve are reciprocating pump special valve groups.But existing combination brake switch and proporting exists area of passage little, and especially the area of snout cavity and valve import causes the flow velocity of medium in the valve body big, can cause the lot of energy loss when medium enters the pump housing, reduces the suction performance of pump.Velocity of medium is excessive simultaneously, cause the Lift of valve collar and valve plate too high, it is closed retardation angle and increases, the backflow of medium increases thereupon, reduce the volumetric coefficient of pump, caused the medium partial pressure to run off energy dissipation, and valve group vibration noise increases the working life of having reduced the valve group during pump operation.In addition, traditional combination brake switch and proporting is unfavorable for the discharge of gas phase media for being horizontally disposed with, and cause and can't carry, even pump lost efficacy.
Summary of the invention
The objective of the invention is provides a kind of area of passage big for the deficiency that solves above-mentioned technology, and the low reciprocating type gas-liquid two-phase of velocity of medium mixes defeated pump with vertical unidirectional combination brake switch and proporting.
In order to achieve the above object, the designed reciprocating type gas-liquid two-phase of the present invention mixes defeated pump with vertical unidirectional combination brake switch and proporting, it mainly comprises valve body, the valve import, valve outlet port, snout cavity and outlet plenum, described valve body vertically is arranged on the cavity hatch place of the pump housing, valve outlet port is arranged on the valve body inner ring, the valve import is arranged on the valve body outer ring, in snout cavity, be provided with valve collar, valve collar is provided with stage clip, stage clip is spacing by the baffle ring that is arranged on the valve body, valve body between snout cavity and the outlet plenum is provided with tap hole, be provided with valve plate at valve outlet port, valve plate is connected with an end of vertical rod, and the end of vertical rod in outlet plenum is provided with the convex edge, is provided with stage clip between the convex edge of vertical rod and valve body.This result's characteristics are: the valve import are arranged on the valve body outer ring, obtain the Flow area of bigger valve import, and the setting of tap hole, the runner that makes medium enter the pump housing is snout cavity and tap hole double flow channel, reaches the purpose of the flow velocity that reduces valve inlet medium.On the other hand, the vertical setting of valve body utilizes the gas natural law different with liquid specific gravity, makes gas phase media than the first discharge of liquid phase medium, improves the compression ratio of pump and to the adaptability and the passing ability of medium.
In order to increase the area of passage of valve body, described valve import, snout cavity and outlet plenum are annular, thereby effectively reduce velocity of medium.
In order further to increase the area of passage of valve body import, the tap hole on the valve body between described snout cavity and the outlet plenum is for evenly arranging.Thereby reach mild velocity of medium, reduce energy loss.
The resulting reciprocating type gas-liquid two-phase of the present invention mixes defeated pump with vertical unidirectional combination brake switch and proporting, and valve outlet port is arranged on the valve body inner ring, and the valve import is arranged on the valve body outer ring, increased the Flow area of valve import, reduce the velocity of medium of valve inlet, can reduce energy loss, improve the suction performance of pump.Valve body between snout cavity and the outlet plenum is provided with tap hole simultaneously, realized the double flow channel structure, further reduce the velocity of medium of valve inlet, can reduce the Lift of valve collar, dwindle the retardation angle that valve collar is closed, reduce the waste of loss of pressure and energy, the vibration noise of combination brake switch and proporting in the time of can also reducing pump operation simultaneously, prolong the working life of combination brake switch and proporting, improve the overall operation performance of pump.
