Description
Technical field
The utility model belongs to fluid technique field, particularly relates to a kind of heat exchange-type fluid buffer, for having high and low temperature, under tightness and high corrosion-resistant operating mode fluid voltage stabilizing and eliminate pulsation, also can be used as the plate type heat exchanger with buffer function.
Background technique
Buffer is a kind of energy savings device in fluid pneumatic system, it is in due course the energy conversion in system is that compression energy or potential energy store, when system needs, again compression energy or potential energy changed into the energy such as fluid or air pressure and discharge, again supply system is mended, when system instantaneous pressure increases, it can absorb this part energy, ensures that whole system pressure is normal.Buffer also can be used to the fluid shock pressure produced in the pressure pulsation of absorption fluids pump or absorption system.The structure that existing buffer is conventional has bellows, diaphragm type and piston type buffer, but the diaphragm element of these three kinds of buffers all be unable to do without capsule material, all by the method buffer isolated component of cooperation, gas, liquid are isolated, inevitably there is certain seepage, the compatibility of diaphragm element and medium also has certain limitation in addition, temperature is also roughly the scope of-40/+120 DEG C, and exceeding above-mentioned condition just can not normal use.
Model utility content
The utility model provides a kind of heat exchange-type fluid buffer, has high and low temperature, under tightness and high corrosion-resistant operating mode fluid voltage stabilizing and eliminate pulsation, also can be used as the plate type heat exchanger with buffer function.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of heat exchange-type fluid buffer, for having height, low temperature, under tightness and high corrosion-resistant operating mode fluid voltage stabilizing and eliminate pulsation, also can be used as the plate type heat exchanger with buffer function, it is characterized in that: comprise cylindrical shell, end cap, blind plate, adapter, bellows, dividing plate and pipeline, described cylindrical shell two ends respectively with described end cap, blind plate connects, form a seal container, described cylindrical shell is provided with adapter, bellows is provided with in cylindrical shell, described bellows one end and described end cap assemble, the other end is connected with described dividing plate, described dividing plate opposite side is provided with pipeline, described end cap there are two perforates, coordinate with the adapter of bellows respectively.
Described dividing plate is equipped with wear ring.
Described bellows material is stainless steel and titanium alloy.
Buffer bellows makes with the material adapted with working medium and operational condition, and as stainless steel and titanium alloy etc., be characterized in having good elasticity and toughness, its manufacture method is welded into the high-energy such as laser, plasma.The bellows of buffer be one with the element of adapter, there is good tightness.The adapter of buffer bellows and end cap are connected and ensure its sealing.Buffer bellows is connected with dividing plate, and dividing plate ensures that buffer bellows keeps it be not subject to the situations such as stuck or torsion and cause buffer bellows to damage in cylindrical shell in movement process.The internal surface of dividing plate and cylindrical shell has certain gap, ensures that guide sleeve moves freely.Buffer is divided into two liquid container by buffer bellows, and two chambeies are different fluids plays liquid stabilizing and heat exchange effect by buffer bellows.
The beneficial effects of the utility model are:
1 the technical program has the fluid cushion voltage stabilizing under higher temperature, and namely he can be used as buffer, also can be used as the plate type heat exchanger with buffer function.The technical program uses the sealing of metal separator,
2. make buffer have good tightness, helium leak test can reach very high rank, can do the application of exigent high-end system.Bellows makes the fluid of both sides have good isolation performance, and helium leak test can reach 10
-7sCC/sec (cubic centimetre per second).The diaphragm element long service life of buffer.
3 cylindrical shells and buffer bellows adopt stainless steel, and antiseptic property is good, and the difference according to medium can select corresponding material, to ensure most effectively and the compatibility of medium, can be used in the system of high corrosion.
4 buffer bellowss are connected with guiding element, effectively can keep separator, ensure the life-span of product.
5 due to all-metal, can adopt the method for welding, avoids the restriction that rubber material causes barrel soldering.
The pressure balance of 6 metal diaphragm elements on either side, can do frivolous by buffer bellows, namely alleviate weight, is conducive to again the ability improving antifatigue.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure: 1-blind plate, 2-seal rubber pad, 3-bolt, 4-nut, 5-flange plate, 6-pipeline, 7-dividing plate, 8-wear-resistant strip, 9-bellows, 10-cylindrical shell, 11-takes over, 12-end cap.
Above is a kind of assembling mode, also can adopt the method for flange or welding (no longer describing in detail).
The present embodiment cylindrical shell 10 is opened two holes and pass through assemble welding with adapter 11.End cap 12 there are two perforates, coordinate with the adapter of the bellows 9 of buffer, undertaken by the method for assembling or welding.Blind plate 1 and cylindrical shell 10 link together, an airtight container is formed with end cap 12, form a complete buffer shell. play the role of pressure, bellows 9 is assembled together with end cap 12 below and has seal request. and its other end is connected with dividing plate 7, as the guiding of bellows 9, move at cylindrical shell 10 internal surface.Dividing plate 7 is equipped with wear ring 8, level and smooth with guiding to ensure the life-span of leading, cylindrical shell 10 inner diameter is greater than the external diameter of wear ring 8, and the external diameter of wear-resistant strip 8 is greater than the external diameter of kicker baffle 7, and kicker baffle 7 is greater than the external diameter of buffering bellows.Cylindrical shell 10 two ends are provided with flange plate 5, be connected with blind plate 1, end cap 12 respectively by bolt 3, nut 4, seal rubber pad 2 is provided with between cylindrical shell 10 and blind plate 1, end cap 12, by end cap 12, metal diaphragm 9 and kicker baffle 8 form a complete buffer bellows, buffer is divided into two parts, has possessed the function of buffering and heat exchange.
