Description
Technical field
The present invention relates to a kind of high-precision voltage stabilizing combination valve, belong to air pressure field, change width especially suitable for inlet pressure
Larger, the metastable baric systerm of export requirement pressure is spent, and there is pressure overload protection function and buffer brake to cut simultaneously
Only function.
Background technology
Existing pneumatic actuator system volume is larger, weight weight.Certain pressurized fuel tank is manufactured using composite, but composite
Intensity is relatively low, and system inlets range of pressure fluctuations is larger, and 15 times of tank design intensity have been reached during inlet pressure maximum.
Therefore need that the annexes such as pressure-reducing valve, safety valve, check valve are installed in pipeline.To ensure that boost pressure is steady in composite fuel tank
It is fixed.
Baric systerm small volume, in light weight is currently required that, but has pressure-reducing valve, safety valve, unidirectional in known baric systerm
Valve three's weight is larger, seriously occupies system weight index, influences overall performance.There is an urgent need to a kind of integrated level height, weight
Gently, decompression, safety valve function, the product of non-return valve function can be had concurrently.
The content of the invention
The task of the present invention is to propose a kind of a kind of compact-sized, high-precision voltage stabilizing combination valve of small volume.
The task of the present invention, which is done in such a way that, is characterized in that：Voltage stabilizing combination valve be by a safety valve, one it is unidirectional
Valve, housing and joint are formed, and are connected through a screw thread between each other, and being put in safe valve core has safety valve, in safety valve
Storing has spring, and the upper ends of the spring have pad, and connect and compose safety by the screw thread in adjusting screw and inserts
Valve, the safety valve are fixedly connected with the casing by screw thread.The air inlet of the housing upper end is integrated with a throttle orifice mouth,
Being put in the valve element of the check valve has check valve, and being put in check valve has spring, passes through being threadedly secured on joint
On housing, the other end of joint is connected with system.Relief hole is machined with the adjusting screw, adjusts the Opening pressure of safety valve
It is to be realized by the thickness of adjust pad.The safety valve is identical with the physical dimension of check valve, safety valve and list
Steel shape is formed to valve using bulb valve and inserts to seal.
The present invention has the following effects that：The technical program is compact-sized, small volume, disclosure satisfy that inlet pressure fluctuation range
It is larger, and outlet pressure will aspire for stability, while there is pressure overload protection function and buffer brake cutoff function, to system pressure
Accurate adjustment, pressure regulation spectrum is big, the high voltage stabilizing combination valve of degree of regulation.
Brief description of the drawings
Fig. 1 is the structural representation of the technical program.
Drawing explanation：1st, throttle orifice mouth, 2, housing, 3, inserts, 4, spring, 5, adjusting screw, 6, sealing ring, 7, safety it is living
Door, 8-6, sealing ring, 9, joint, 10-4, spring, 11, check valve.
Embodiment
The voltage stabilizing combination valve that the technical program is related to is made up of a safety valve, a check valve, housing and joint, phase
Mutually between be connected through a screw thread, it is therefore an objective to space is saved, using combining structure, it is desirable at the same have pressure overload protection function and
The baric systerm of buffer brake cutoff function.
Embodiment is described in detail with reference to the figures above, being put in safe valve core has safety valve 7, is put in safety valve
There is spring 4, the upper ends of the spring 4 have pad, and connect and compose peace by the screw thread 104 in adjusting screw 5 and inserts 3
Full valve, relief hole is machined with the adjusting screw, the Opening pressure for adjusting safety valve is come real by the thickness of adjust pad
It is existing.
The safety valve is to be fixedly connected by screw thread 103 with housing 2.
The air inlet of the upper end of housing 2 is integrated with a throttle orifice mouth 1, and being put in the valve element of the check valve has unidirectionally
Valve 11, putting in check valve has spring 10-4, is fixed on by the screw thread 105 on joint 9 on housing, joint 9 it is another
End is connected with system.
The safety valve is identical with the physical dimension of check valve, and safety valve and check valve are lived using bulb
Door forms steel shape with inserts 3 and sealed, and ensures sealed reliable and life.
The throttle orifice mouth is to play metering function, and the sealing ring 6 and another sealing ring 8-6 be when being used to seal,
Throttle orifice mouth pore size is determined by the combination property of safety valve and check valve.
Product is imported and exported uses I serial screw connection structures of HB4-3-2002 with the connected mode of system（101 in figure,
102nd, 103,104,105 be screw thread sequence number）.
During work, air is by throttle orifice mouth current limliting before valve, and stable air-flow enters in combination valve, when system pressure is low
When, one-way cock opens the fuel-tank pressurization to system, and when pressure is excessive, while check valve is opened, safety valve 7 is also beaten
Open, by the outwardly pressure release of the relief hole on screw, so as to ensure that the pressure after combination valve is the steady pressure of system requirements.
