Abstract
This utility model relates to a pressure gauge damper, consisting of a casing, a connecting pipe, a communication valve and a cock joint. The casing is a cylindrical container, on top of which the connecting pipe communicated with the pressure gauge is connected by insertion, and at the bottom of which is a seal inclined board, which is paralleled with a damping separator at the lower part of the cylindrical container divided into upper and lower chamber by the damping separator. Blind pipes with holes on the side are welded onto the seal inclined board and the damping separator, and the blind pipes on the seal inclined board are connected with the cock joints welded on the water supply pipe through the communication valve. When the water pump starts and stops and the pressure fluctuate suddenly, the pressure indication of the electro connecting pressure gauge fluctuates stably and in consistence with the actual pressure in the main pipeline, ensuring the lasting and stable operation of the automatic control system of water source wells.
Description
Technical field: the utility model relates to a kind of pressure ga(u)ge damper, belongs to industrial automation control instrument instrument, especially slows down the snubber assembly technical field of tensimeter meter compression shock.
Background technology: oil is distinguished opening automatically, stopping of water supply well, normally rely on the pressure of water system pipeline to control, its control principle is: at the bottom of water system pressure in setting lower limit be, contactor gets electric adhesive, pump starts, when water system pressure is higher than capping, and the auxiliary reclay adhesive, the contactor outage discharges, and pump stops.Because the water supply well pump opens, the stopping time, in the well head pipeline, be easy to generate water hammer, and impact the electro connecting pressure gauge meter rapidly, make the table meter fluctuation of control system pressure bigger, be difficult to accurately control, setting pressure table buffering device between tensimeter meter and systematic pipeline for this reason.Be bourdon tube with pressure buffer device at present, this device has the cock joint, being communicated with valve and bourdon tube forms, this device has slowed down the fluctuation imagination of table meter to a certain extent, but because the water attack of liquid is to transmit to all directions with the form of ripple, and speed is very fast, the wave phenomenon of liquid can be directly reflected on the electro connecting pressure gauge when water attack and pressure frequent fluctuation appear in system, make pressure indicator left and right sides frequent swing, cause the motor frequent start-stop, thereby cause pump and circuit to damage, be difficult to guarantee the operate as normal of automatic start-stop system, realization of automatic control is made a big impact.
Summary of the invention: the purpose of this utility model is can not well alleviate because water attack to the defective that electro connecting pressure gauge impacts, designs a kind of pressure ga(u)ge damper that guarantees pump automatic start-stop system operate as normal at the bourdon tube of prior art.
The utility model is made up of housing, communicating pipe, connection valve, cock joint, housing is a hydrostatic column, its upper end is plugged with the connecting pipe that communicates with tensimeter, the bottom is the sealing swash plate, Lower Half in hydrostatic column is provided with and seals the buffering dividing plate that swash plate is parallel to each other, the buffering dividing plate is divided into upper and lower two chambers with hydrostatic column, be welded with the blind pipe of side perforate on the dividing plate respectively in sealing swash plate and buffering, the blind pipe on the sealing swash plate is connected with cock joint on being welded on water supply line through being communicated with valve; On the bottom shell of sealing swash plate and buffering dividing plate, also be separately installed with blowoff valve.
Invention effect: when the utility model opens, stops with rapid pressure fluctuation at water pump, the electro connecting pressure gauge indicated pressure is steadily lifting all the time, and remain consistent with the main line normal pressure, avoided because of the impact of water attack and pressure jump fluctuation electro connecting pressure gauge, thus guaranteed the water supply well automatic control system for a long time, operation reposefully.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The utility model is by housing 7, communicating pipe 8, be communicated with valve 2, cock joint 1 is formed, housing 7 is a hydrostatic column, its upper end is plugged with the connecting pipe 8 that communicates with tensimeter 16, the bottom is sealing swash plate 4, Lower Half in hydrostatic column is provided with and seals the buffering dividing plate 5 that swash plate 4 is parallel to each other, hydrostatic column is divided into, following two chambers, on sealing swash plate 4 and buffering dividing plate 5, be welded with the blind pipe 3 and 12 of side perforate respectively, liquid in buffering dividing plate 5 and the hydrostatic column will be divided into steady liquid zone 13 at hydrostatic column, 15 3 districts in hydrodynamic district 14 and pressurized air district, the blind pipe 3 of sealing on the swash plate 4 is connected with cock joint 1 on being welded on water supply line through being communicated with valve 2; On the bottom shell 7 of sealing swash plate 4 and buffering dividing plate 5, also be separately installed with blowoff valve 9 and 10.
Embodiment
The water attack that produces in the pipeline 17, successively through cock joint 1, be communicated with valve 2, the side opening of blind pipe 3 enters the steady liquid zone 13 of lower chamber, shock wave to water attack has carried out one-level filtering, the side opening of the blind pipe 12 on buffering dividing plate 5 enters upper chamber hydrodynamic district 14 again, shock wave to water attack has carried out secondary filtering, transmit distance and passing time to prolong fluid, increase the linear loss of current, weaken the water attack energy, the liquid that reduces communicating pipe 8 is subjected to the influence of water system pressure surge, just pressure is passed to electro connecting pressure gauge 16 by communicating pipe 8 then, thereby eliminate water attack electro connecting pressure gauge is impacted, guarantee that the pump automatic start-stop system is long-term, operation reposefully.
