Abstract
The invention discloses a simple flow control switch. The flow control switch consists of a valve body, a valve seat and an elastomer, wherein two joints which are connected with an inlet and an outlet of a fluid are formed in the valve body; the valve seat is fixed in the valve body and is positioned between the two joints of the valve body; and the elastomer is fixed on the valve body and can open or seal the valve seat according to the undulatory motion of pressure change in the valve body. The flow control switch has the elastomer which can be retracted by the change of the pressure in a flow channel, so that the elastomer (or a valve core) and the valve seat are pressed tightly or separated from each other to play a role of opening/closing. The flow control switch has a simple structure, is small in size and low in cost, and acts reliably.
Description
Technical field
The present invention relates to be specially a kind of flow control switch by bellows or bellows, control Fluid Flow in A field.
Background technique
The condenser for refrigerator pressure-retaining system has two kinds at present.A kind ofly be comprised of solenoid valve and one-way valve, when compressor shutdown, these two valves cut out together, the refrigeration agent in the condenser are enclosed in the condenser, until during the next time start.This solenoid valve price is high, and reliability is low.Another kind is comprised of float valve and one-way valve, and this float valve volume is large, complex structure.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, reliability is high, volume is little reduced form flow control switch.
The present invention solves the problems of the technologies described above the technological scheme that adopts: a kind of reduced form flow control switch, formed by valve body, valve seat and elastomer, be shaped with 2 on the valve body and be used for two interfaces being connected with import and the outlet of fluid, it is interior and in valve body between two interfaces that valve seat is fixed in valve body; Be fixed with elastomer on the valve body, and elastomer changes phugoid motion realization opening or sealing valve seat according to the pressure in the valve body.
The present invention can have following four kinds of concrete distressed structures under above-mentioned thinking:
1, the valve body middle part is shaped with the cavity for containing fluid, and elastomer is diaphragm and is fixed in this cavity one opening end.Valve seat is the pipe that an end is shaped with connecting ring, and an end is connected on the valve interior wall by connecting ring, and an other end withstands on the elastomer.
2, valve seat is that a centre is shaped with fluid by the disk in hole, valve rod is installed at fluid in by the hole, and valve rod withstands on the elastomer, promotes valve rod by elastomer and is pressed in the valve seat fluid by realizing the sealing of fluid valve on the hole.
3, be connected with spring at valve rod, the other end of spring is fixed on the valve body.
4, valve body middle part is shaped with the cavity for containing fluid, and valve seat is that a centre is shaped with fluid by the disk in hole, and elastomer is that bellows or other plastomer and an end are fixed on the valve interior wall, and the other end of elastomer withstands on that sealing fluid passes through the hole on the valve seat.
The present invention is owing to having an elastomer, and this elastomer is owing to the variation of pressure in the runner stretch, thereby makes elastomer (or spool) compression or disengaging valve seat, plays on-off action.Have simple in structure, reliable in action, volume is little, cost is low characteristics.

Embodiment:
A kind of flow control switch, it has the switch that is comprised of valve body, valve seat and elastomer; Be shaped with 2 on the valve body and be used for the interface that is connected with import and the outlet of fluid, have an elastomer, this elastomer is owing to the variation of pressure in the runner is stretched, thereby makes elastomer (or spool) compression or disengaging valve seat, plays on-off action.
1-4 is described in further detail the present invention below in conjunction with accompanying drawing.
Embodiment one
As shown in Figure 1, the present embodiment flow control switch, it has diaphragm 3, valve body 1 and valve seat 2, connects in addition two interfaces of fluid circuit on the valve body.When having high-pressure liquid to come in the runner, diaphragm 3 is upspring and is lifted off a seat 2, valve open; When pressure drop, diaphragm 3 is pushed down valve seat 2, valve closing.Described elastomer is diaphragm, and diaphragm directly is pressed on the valve seat; When having high-pressure liquid to come in the runner, diaphragm is upspring, and breaks away from valve seat, valve open; When not having pressure in the runner, diaphragm compresses valve seat, stops and leaks.
Embodiment two
As shown in Figure 2, the present embodiment flow control switch, it has diaphragm 3, valve body 1, valve rod 4 and valve seat 2, connects in addition two interfaces of fluid circuit on the valve body 1.When having high-pressure liquid to come in the runner, diaphragm 3 is upspring, and valve rod 4 falls lifts off a seat valve open; When pressure drop, diaphragm 3 promotes valve rod 4 and pushes down valve seat, valve closing.Described elastomer is diaphragm, and pressing diaphragm is on valve rod, and valve rod is pressed on the valve seat; When having high-pressure liquid to come in the runner, diaphragm is upspring, and valve rod falls, valve open; When not having pressure in the runner, diaphragm promotes valve rod and compresses valve seat, stops and leaks.
Embodiment three
As shown in Figure 3, the present embodiment flow control switch, it has diaphragm 3, valve body 1, valve rod 4, and spring 5 and valve seat 2 connect two interfaces of fluid circuit in addition on the valve body 1.When having high-pressure liquid to come in the runner, diaphragm 3 is upspring, and valve rod 4 breaks away from valve seat 2, valve open under spring 5 effects; When pressure drop, diaphragm 3 promotes valve rod 4 and pushes down valve seat, valve closing.Described elastomer is diaphragm, and pressing diaphragm is on valve rod, and valve rod is pressed on the valve seat, and spring is pressed in valve rod on the diaphragm when diaphragm is upspring; When having high-pressure liquid to come in the runner, diaphragm is upspring, and spring is pressed in valve rod on the diaphragm, valve open; When not having pressure in the runner, diaphragm promotes valve rod and compresses valve seat, stops and leaks.
Embodiment four
As shown in Figure 4, the present embodiment flow control switch, it has elastomer 3, valve body 1 and valve seat 2, connects in addition two interfaces of fluid circuit on the valve body.Elastomer 3 one ends are fixed on the valve body 1.When having high-pressure liquid to come in the runner, elastomer 3 is out of shape by compression and shortens, and lifts off a seat 2, valve open; When pressure drop, valve seat 2, valve closing are pushed down in elastomer 3 elongations.Described elastomer is bellows (perhaps other plastomer), and bellows directly is pressed on the valve seat, and the other end is fixed on the valve body; When having high-pressure liquid to come in the runner, bellows (perhaps other plastomer) shortens by compression, breaks away from valve seat, valve open; When not having pressure in the runner, bellows (perhaps other plastomer) thus elongation compresses valve seat, stop to leak.
