Embodiment
Core of the present utility model is to provide a kind of diaphragm type one-way valve, and the reliability of this diaphragm type one-way valve is higher.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 2, Fig. 2 provides the structural representation of a kind of embodiment of diaphragm type one-way valve for the utility model.
In this embodiment, described diaphragm type one-way valve comprises valve body 10, has valve seat 20 and the diaphragm 50 of valve port.
Valve body 10 has fluid inlet 10a and fluid output 10b.
Valve seat 20 is fixedly arranged in valve body 10, and diaphragm 50 can move axially to open or close along valve body 10 valve port of valve seat 20.
Wherein, the valve seat that valve seat 20 is made for magnetic material, the diaphragm that diaphragm 50 is made for permeability magnetic material, diaphragm 50 can be shifted to valve seat 20 to seal described valve port under the adhesive effect of valve seat 20.
Because valve seat 20 is made by magnetic material, can replace the magnetic stripe in background technique, cancel the diaphragm type one-way valve of magnetic stripe, on the one hand, can increase circulation area, reduce flow resistance, under the prerequisite of valve body 10 size constancies, improve flow, on the other hand, valve seat 20 integral body have magnetic, and the suction-combining force that diaphragm 50 is subject to, than more even in background technique, makes the action of diaphragm 50 more stable; Meanwhile, there is not the come off risk of product failure of magnetic stripe yet, and, simplified technique, to compare with background technique, the reliability of this diaphragm type one-way valve is higher, and cost is lower.
In concrete scheme, valve seat 20 can be made by soft-magnetic stainless steel, certainly, also can select other magnetic materials.
Further, valve seat 20 is fixing by mode and the valve body 10 of cutting welding.
So, can be high in conjunction with cutting intensity, the reliable advantage of welded seal.
This means of fixation has been avoided simple groove structure, valve body 10 and valve seat 20 cause the difference of the rate of expanding with heat and contract with cold because of material difference, cause product to exist internal leakage bad when work, while also having avoided simple welding, adhesive strength is not enough simultaneously, has further improved the reliability of product.
In concrete scheme, valve seat 20 peripheries offer the first groove 20b and the second groove 20c, and wherein, the first groove 20b is for affixed by cutting mode with valve body 10, and the second groove 20c is for pre-slugging circle.
When fixed valve base 20 and valve body 10, first cutting, then weld by the weldering circle being embedded in the second groove 20c.Conventionally, choose the mode of soldering during welding.
Further, the outer circumferential face of valve seat 20 has the red copper of plating layer, so, facilitates valve seat 20 and valve body 10 welding.
Further, diaphragm 50 has PTFE (Polytetrafluoroethylene, teflon) coating for the sealing surface of the sealing valve port with valve seat 20.
Sealability in order to ensure diaphragm 50 with valve port, high for the planeness requirement of diaphragm 50 sealing surfaces, when diaphragm 50 is ground, because its milling area is larger, if amount of grinding is little, be difficult to polish, if amount of grinding is too large, cost is too high, and diaphragm 50 is easily out of shape.
As above,, in the sealing surface increase PTFE of diaphragm 50 coating, can reduce grinding difficulty; With rubber coating comparison conventional in prior art, wear resistance, the sealing of PTFE coating are better, can avoid rubber coating easily aging, High Temperature High Pressure position is prone to the shortcomings such as wear out failure, and, noise when PTFE coating can also effectively reduce product operation, in addition, the setting of PTFE coating makes the product can compatible different coolant media, and Applicable scope is wider.
This diaphragm type one-way valve also comprises the back-up ring 60 being fixedly arranged in valve body 10, and the movement that this back-up ring 60 is included as diaphragm 50 provides the guide portion of guiding, and the limited part of limiting diaphragm 50 displacement distances.
So, both stationarity and the reliability of diaphragm 50 actions can have been guaranteed, avoid diaphragm 50 to depart from and valve port described in cannot effective sealing, can also guarantee that diaphragm 50 is within the scope of the suction-combining force of valve seat 20, avoid diaphragm 50 because displacement distance is excessive, cannot shift to the described valve port of valve seat 20 sealing.
In concrete scheme, back-up ring 60 can by cutting or get mode ready and valve body 10 fixing, convenient reliable again.Certainly, during actual setting, also can adopt other reliable means of fixation.
This diaphragm type one-way valve also comprises net-filter assembly 30, and this net-filter assembly 30 is fixed in valve seat 20 near one end of fluid inlet 10a.
So, can filter the impurity in refrigerant, avoid entering of impurity to affect systematic function.
In concrete scheme, net-filter assembly 30 can be fixed on valve seat 20 by welding manner, easy to be reliable.Certainly, can also fix by other means, be not limited to welding.
During work, refrigerant flows into from the fluid inlet 10a of diaphragm type one-way valve, when the refrigerant flowing into makes the difference force of fluid inlet 10a one end and fluid output 10b one end be greater than valve seat 20 for the suction-combining force of diaphragm 50, diaphragm 50 is promoted by difference force, moves, and move to the limited part position of back-up ring 60 to the direction away from valve port, now, diaphragm type one-way valve is opened, and refrigerant can, by fluid inlet 10a through valve port effluent fluid outlet 10b, enter refrigeration system; When the difference force of fluid inlet 10a one end and fluid output 10b one end is less than valve seat 20 for the suction-combining force of diaphragm 50, diaphragm 50 is under the suction-combining force effect of valve seat 20, to valve seat 20 directions, move to and valve seat 20 adhesives, now, the valve port of the sealing surface seal valve seat 20 of diaphragm 50, diaphragm type one-way valve is closed, and refrigerant flows and is cut off.
Above diaphragm type one-way valve provided by the utility model is described in detail.Applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
