Abstract
The utility model relates to a memory alloy one-way valve. A memory alloy pressing spring is arranged at the left side of an inner cavity of a valve body, a valve plug is arranged at the right side, back springs are arranged at the right side of the valve plug and an inner cavity of a valve cover, and the valve cover is fixedly arranged at the right end of the valve body. The utility model uses the temperature-sensing function of the memory alloy pressing spring of the valve to open and close the valve.
Description
Technical field
The utility model relates to a kind ofly controls the device of fluid motion automatically with temperature, especially be applicable in the oil hydraulic circuit of chemical-process, and the memory alloy one-way valve of the part of the hydraulic control in the heavy industry machinery.
Background technique
At present, known one-way valve, only relevant with the pressure of fluid in the pipeline, and temperature independent, the constant pressure in pipeline like this, and under the situation that temperature raises can cause pipeline wearing and tearing, the overheated medium influential environment that both consumed energy, even hurt sb.'s feelings.Domestic still do not have in chemical-process this temperature of use, pressure fluid control valve, an one-way valve that more useless memory alloy material is made.
Summary of the invention
In order to overcome the deficiency that existing one-way valve can not temperature control, the utility model provides a kind of memory alloy one-way valve that can pilot pressure can control temperature again.
The technological scheme that its technical problem that solves the utility model adopts is: the inner chamber left at valve body is equipped with the memory alloy stage clip, at its right-hand valve plug that is equipped with, inner chamber at the right-hand and valve gap of valve plug is equipped with back of the body spring, and valve gap is packed in the valve body right-hand member, constitutes the memory alloy one-way valve.Utilize this valve memory alloy stage clip to control the keying of memory alloy one-way valve according to the temperature variation of fluid in the pipeline.The memory alloy stage clip adopts NiTi, NiTiCu, and the CuAlBeX alloy is made.
The beneficial effects of the utility model are, install easily, and are easy to use, and reliable operation is simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structure diagram.
Embodiment
In Fig. 1, at the inner chamber left of valve body 1 memory alloy stage clip 5 is housed, at its right-hand valve plug 4 that is equipped with, back of the body spring 3 is housed at the inner chamber of the right-hand and valve gap 2 of valve plug 4, valve gap 2 is packed in valve body 1 right-hand member and constitutes the memory alloy one-way valve jointly.
When the fluid temperature (F.T.) in the pipeline surpassed 50 ℃ ± 2 ℃, memory alloy stage clip 5 stretched automatically, overcame making a concerted effort of back of the body spring 3 and hydrodynamic pressure, made it promote valve plug 4 right laterals, and throttle down stops media flow; When the temperature of fluid was lower than 50 ℃ ± 2 ℃, memory alloy stage clip 5 was softening, the making a concerted effort of back of the body spring 3 and hydrodynamic pressure promoted valve plug 4 left lateral greater than the elastic force of memory alloy stage clip 5, opened valve.By the temperature-sensitive effect of memory alloy stage clip 5, throttle down again when guaranteeing that fluid temperature (F.T.) surpasses 50 ℃ ± 2 ℃.
Claims (2)
1. memory alloy one-way valve, it is characterized in that: the inner chamber left at valve body is equipped with the memory alloy stage clip, at its right-hand valve plug that is equipped with, at the inner chamber of the right-hand and valve plug of valve plug back of the body spring is housed, and valve gap is packed in the valve body right-hand member and constitutes this valve.
2. according to claims 1 described one-way valve, it is characterized in that: the memory alloy stage clip adopts NiTi, and CuAlBeX or CuAlMnX alloy are made.
