Description
Technical field
The present invention relates to field, especially a kind of two-position three-way valve suitable for low viscosity fluid.
Background technology
Two-position three-way valve of the prior art, the generally structure type that uses for:Including valve element and valve body, adopt between the two
With the sliding valve structure form of clearance seal mode, be typically only used for sealing the larger fluid of viscosity (such as hydraulic oil, lubricating oil,
Emulsion etc.).When used for the sealing less fluid of viscosity (such as seawater, fresh water, ethylene glycol), it usually needs use cone valve structure
Form, can only synthesize two-bit triplet valve group, so with two 2/2-way valves using the mode that pipeline or valve plate carry out parallel connection
Complex structure, high cost.
The content of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, there is provided a kind of two three suitable for low viscosity fluid
Port valve, it uses cone valve structure form, is capable of achieving the reliable sealing of small viscosity fluid.Valve is caused by the driving force of drive part
Body is conjugated, and realizes the function of two-bit triplet.
The technical solution adopted in the present invention is as follows：
A kind of two-position three-way valve suitable for low viscosity fluid, including valve body, are provided with valve element, institute in the middle part of the valve body
Bonnet is installed in the one end for stating valve body, and the outer circumference surface of the bonnet is described by the second O-ring and the second back-up ring and valve seal
The end face of bonnet is locked by screw with valve body；One end of the valve element is connected with valve body, the other end of the valve element with
Bonnet is connected, and is installed by the first O-ring and the first retaining ring sealing；And it is formed with input port and defeated at the two ends of valve body
Outlet；P1 mouthfuls and P2 mouthfuls is provided with the top of the valve body, the front end face two ends of the valve body are blocked and second with first respectively
Blocking is sealed, while being provided with P mouthfuls on the valve body of second blocking one side.
Phase, further technical scheme was：
The valve element across structure, is provided with installation the first O-ring and first gear on the horizontal component of the valve element
The groove of circle, the vertical component outer ring of the valve element is again provided with groove, the tapered knot in two ends termination of the horizontal component
Structure.
Beneficial effects of the present invention are as follows：
Compact conformation of the present invention, rationally, it is easy to operate, by use cone valve structure form, realize the function of two-bit triplet,
Two valves need not be used, space is greatlyd save, cost is reduced.
The present invention is mainly suitable for the two-position three-way valve of low viscosity fluid, it can be with traditional two-position three-way valve ratio, its
Using cone valve structure form, therefore the less fluid of viscosity can be sealed.

Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is illustrated.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the two-position three-way valve suitable for low viscosity fluid of the present embodiment, including valve
Body 1, the middle part of valve body 1 is provided with valve element 5, and bonnet 4 is installed in one end of valve body 1, and the outer circumference surface of bonnet 4 passes through the second O-ring 8
Sealed with the second back-up ring 9 and valve body 1, the end face of bonnet 4 is locked by screw 10 with valve body 1；Match somebody with somebody with valve body 1 one end of valve element 5
Connection is closed, the other end and the bonnet 4 of valve element 5 are connected, sealed by the first O-ring 6 and the first back-up ring 7 and installed；And
The two ends of valve body 1 are formed with input port and delivery outlet；The top of valve body 1 is provided with P1 mouthfuls 12 and P2 mouthfuls 13, the front end face of valve body 1
Two ends are sealed with the first blocking 2 and the second blocking 3 respectively, while being provided with P mouthfuls 11 on the valve body 1 of second 3 one sides of blocking.
The across structure of valve element 5, is provided with installation the first O-ring 6 and the first back-up ring 7 on the horizontal component 503 of valve element 5
Groove 502, the outer ring of vertical component 504 of valve element 5 is again provided with groove 502, and the two ends termination of horizontal component 503 is tapered
Structure 501.
Of the present invention first blocks technological requirement when the 2, second blocking 3 is processed for valve body 1.
P mouthfuls 11, input port and delivery outlet are the connector of low viscosity fluid, and P1 mouthfuls 12, P2 mouthfuls 13 is the drive of driving pressure
Open one's mouth.So, valve element 5 can P1 mouthfuls 12 or P2 mouthfuls 13 control pressure effect under left and right sidesing shifting.
Operation principle of the invention is as follows：When control pressure from P2 mouthfuls 13 input when, the position of valve element 5 as shown in FIG., P mouthfuls
11 and the connector between the input port of the left end of valve body 1 be closed, P mouthfuls 11 communicates with delivery outlet；When control pressure from P1
When mouth 12 is input into, clack box moves right, and the P mouthfuls of connector between 11 and delivery outlet is closed, and P mouthfuls 11 communicates with input port.It is logical
Crossing the input of control pressure carries out the transposition action of valve element 5, so as to realize the threeway cutoff function of this valve.Simultaneously as valve element 5
The hard seal form of cone mouth is used and valve body 1 between, therefore the less fluid of viscosity can be ended.
Above description is explanation of the invention, is not the restriction to inventing, and limited range of the present invention is referring to right
It is required that, within protection scope of the present invention, any type of modification can be made.
