Abstract
The utility model discloses a liquid high-pressure pressure buffer which comprises a shell and a floating ball. Shoulders are arranged on two ends of an inner cavity of the shell, and the floating ball is arranged inside the inner cavity of the shell; and an external end of the shell is provided with a joint. The liquid high-pressure pressure buffer of the utility model is connected to a liquid pipe, and when an instant liquid high pressure is produced inside the pipe, the floating ball is rapidly raised in a high-pressure effect, which plugs mouths of the shoulders, therefore avoiding destructive impact of high pressure to a pressure meter, thus anti-impact protection to the pressure meter is obtained. The utility model has advantages of simple structure, low cost and good protecting effect, which is suitable for anti-impact protection for the pressure meters of various pressure pump systems such as factories and mines production, firewater and urban life water supply, etc.
Description
Technical field:
The present invention relates to manometer shock resistance protective device in a kind of liquid pressurized pump system, be specifically related to a kind of liquid high pressure pulsation dampener.
Background technology:
When deep well water pump, force (forcing) pump and each class I liquid I pump start-stop, because water hammer to the impact of pipe network, causes ductwork pressure instrument and pressure unit overload and damages.Conventional buffering way is to utilize U-shaped pipe and coiled pipe, but surge pressure does not have protective effect during greater than instrument range.For avoiding this damage, choose the big instrument of range usually, and measurement range is too big, can influence measuring accuracy, increase the cost of buying instrument simultaneously.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, and is with low cost, to the effective liquid high pressure pulsation dampener of instrument shock resistance protection.
Liquid high pressure pressure of the present utility model delays device, is connected on the highly pressurised liquid pipeline, is made up of housing, ball float, and housing inner chamber two ends have shoulder, and ball float is arranged in the housing inner chamber; The housing outer end has joint.
Fluid pressure impact damper of the present utility model; when producing moment in the pipeline during liquid high pressure, hollow ball rises under the high pressure effect rapidly, shutoff shoulder mouth; thereby stoped the damaging impact of liquid high pressure, realized shock resistance protection manometer to manometer or pressure unit.The utility model is simple in structure, and is with low cost, protects effectively, can be applicable to the protection of manometer and pressure unit in each class I liquid I pressurized pump system such as factories and miness production, fire demand water, urban life water supply.
Description of drawings:
Fig. 1 is a liquid high pressure pulsation dampener structural representation.
Embodiment:
As shown in Figure 1, pulsation dampener is made up of housing 1, ball float 2, and the housing outer end has joint 4, and the housing inner chamber has shoulder 3 near the two ends of joint, and ball float 2 is arranged in the housing inner chamber.Pulsation dampener inserts in the fluid pipeline by joint 4, and piping system has manometer.
Ball float weight is slightly less than the buoyancy of this hollow ball in water.
Ball float can be metal hollow ball, and the ball float of present embodiment is the stainless steel hollow ball.When the liquid pump start-stop in the pressurized pump system, produced the moment liquid high pressure by the A direction, high pressure makes ball float 2 rise rapidly, shutoff shoulder mouth has stoped the transmission of liquid high pressure, thereby has avoided the impact failure of high pressure to manometer.After the instantaneous pressure, the liquid that ball float 2 tops are urged can be given downward pressure of ball float, and ball float resets.
