Abstract

The utility model discloses an expansion valve gas tank head inner drive piece guide structure, comprising a gas tank head subassembly which is assembled together by a drive piece, a membrane, a gas tank cover and a gas tank seat. A guiding elastic element positioned below the drive piece and fixed on the gas tank seat or the drive piece is arranged between the drive piece and the gas tank seat. For the guiding elastic element is installed between the drive piece and the gas box seat, the utility model assures the coaxiality of the shaft center of the membrane and the shaft center of the drive piece to be in required range. In the process of transferring the force, an upper drive rod does not generate avertence, the steady force transferring makes upward or downward movement of a steel ball become more reliable and much steadier to control flow quantity. The utility model has advantages of simple structure, reasonable design, good use effect, etc.

Description

The guide structure of driver blade in the expansion valve air tank head
Technical field
The utility model relates in a kind of expansion valve air tank head parts, the motion of driver blade can keep coaxality with diaphragm, makes motion driver blade guide structure more reliably, belongs to the internal structure of expansion valve air tank head parts.
Background technique
In the prior art, expansion valve air tank head parts mainly cover 3 gentle blocks 4 by driver blade 1 and diaphragm 2 with gas tank and are assembled, wherein driver blade 1 is in unfixed moving position in air tank head, this just causes product after assembling is finished easily, the position meeting Off center of driver blade, driver blade makes the drive link deflection easily in the process of transmitting pressure, cause the temperature-sensitive power of air tank head inside to transmit instability, directly have influence on the air-conditioning system reliability of operation.As shown in Figure 1, under perfect condition, diaphragm 1, driver blade 1, last drive link 5, underdrive bar 6, steel ball 7 should be on the same axis.When air tank head is experienced the degree of superheat at evaporator outlet place, the inner medium of enclosing of air tank head produces a power can for diaphragm 2, this power is transmitted by driver blade 1, last drive link 5, underdrive bar 6, act on then on the steel ball 7, the motion that steel ball 7 is produced up or down, thereby the size of control orifice flows in the vaporizer suitable refrigerant; And actual because driver blade in air tank head relative to moving with diaphragm, the axle center of driver blade and the axle center of Nong sheet are not overlapped, cause the drive link deflection, thereby it is unstable to exert all one's strength in transmittance process, steel ball 7 can't be reliably, the size of control orifice stably.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and driver blade guide structure in a kind of improved, expansion valve air tank head of driver blade being carried out leading role is provided.It comprises by driver blade and diaphragm covers the air tank head parts that gentle block is assembled into gas tank, is provided with the guiding elastic element between driver blade and gas tank seat.
Described guiding elastic element is positioned at the below of driver blade, and is fixed on gas tank seat or the driver blade.
The utility model is owing to be equipped with a guiding elastic element between driver blade and gas tank seat, the coaxality that has guaranteed diaphragm axle center and driver blade axle center is in claimed range, in the process of the power of transmission, last drive link can not produce deflection, the transmission of power is stable, makes steel ball motion up or down become more reliably, more stably control cold medium flux; Have simple in structure, reasonable in design, characteristics such as using effect is good.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the structural representation that guiding elastic element of the present utility model is fixed on the gas tank seat.
Fig. 4 is the structural representation that guiding elastic element of the present utility model is fixed on driver blade.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 2, the utility model mainly includes by driver blade 1 and diaphragm 2 and covers the air tank head parts that 3 gentle blocks 4 are assembled into gas tank, is provided with guiding elastic element 8 between driver blade 1 and gas tank seat 4.
Described guiding elastic element 8 is positioned at the below of driver blade 1, and is fixed on gas tank seat 4 or the driver blade 1.The utility model only moves up and down the motion of driver blade 1 in gas tank seat 4 owing to increased guiding elastic element 8, has guaranteed the coaxality requirement of driver blade 1 with diaphragm 2.When air tank head is experienced the degree of superheat at evaporator outlet place, the inner medium of enclosing of air tank head produces a power F can for diaphragm 2, this power is transmitted by driver blade 1, last drive link 5, underdrive bar 6, acts on then on the steel ball 7, makes steel ball generation motion up or down.In the process of the power of transmission F, last drive link 5 can not produce deflection, and power F transmits stable, and steel ball 7 motion is up or down become reliably, makes in the suitable refrigerant inflow evaporator.Shown in Figure 3, guiding elastic element 8 described in the utility model is fixed on the gas tank seat 4; Shown in Figure 4, described guiding elastic element 8 is fixed on the driver blade 1.The utility model is owing to be equipped with a guiding elastic element between driver blade and gas tank seat, the coaxality that has guaranteed diaphragm axle center and driver blade axle center is in claimed range, in the process of the power of transmission, last drive link can not produce deflection, the transmission of power is stable, makes steel ball motion up or down become more reliably, more stably control cold medium flux.

Claims (2)

1, driver blade guide structure in a kind of expansion valve air tank head, it includes by driver blade and diaphragm and covers the air tank head parts that gentle block is assembled into gas tank, it is characterized in that being provided with between driver blade (1) and gas tank seat (4) guiding elastic element (8).
2, driver blade guide structure in the expansion valve air tank head according to claim 1 is characterized in that described guiding elastic element (8) is positioned at the below of driver blade (1), and is fixed on gas tank seat (4) or the driver blade (1).
