Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 2-3: a kind of three-way diverter valve, comprise valve body 4, a side perpendicular to axial direction on the valve body 4 is provided with water intake 1, opposite side is provided with main water outlet 2, is parallel to an axial end on the valve body 4 and is provided with bypass outlet 3, and the other end is installed end cap 5 hermetically, in the described valve body 4 main valve stem E3 is installed slidably, the end towards end cap of described main valve stem E3 connects linear shuttle mechanism, and described linear shuttle mechanism is linear electric motor, and described main valve stem E3 goes up and connects Returnning spring E6; Described main valve stem E3 goes up the main valve plug E1 of suit one hollow, be provided with the primary sealing area B and the secondary sealing area A that cooperate respectively with the two ends of main valve plug E1 in the described valve body 4, the end towards end cap of described main valve plug E1 cooperates formation to be communicated with the primary valve of water intake 1 and main water outlet 2 with primary sealing area B, and the end away from end cap of described main valve plug E1 is communicated with water intake 1 with secondary sealing area A cooperation formation and exports 3 bypass valve port with bypass; The passage that described water intake 1, main valve plug inner chamber, body cavity three are communicated with is arranged on the described main valve plug E1; Described main valve plug E1 is provided with opening at the end away from end cap, described main valve stem E3 connects pressure releasing valve core D1 at the end away from end cap, described pressure releasing valve core D1 goes up and connects pressure release spring D2, and the exterior edge face of described pressure releasing valve core D1 cooperates formation to be communicated with the pressure release valve port D4 of main valve plug inner chamber and bypass outlet 3 with the outer rim of described opening.
Described main valve stem E3 goes up return spring holder E7 is installed, and described Returnning spring E6 is resisted against between valve interior wall and the described return spring holder E7.
Described pressure releasing valve core D1 goes up suit pressure release spring seat D3, and described pressure release spring D2 is installed on the described pressure release spring seat D3.
Described main valve stem E3 is located on the described end cap 5, seals by y-type seal ring C between main valve stem E3 and the end cap.
Be set with buffer casting E4 on the described main valve stem E3, damping spring E2 is resisted against between buffer casting E4 and the described return spring holder E7.
O RunddichtringO E5 is equipped with at the two ends of described main valve plug E1.
The working principle of present embodiment is as follows:
Adopt single main valve plug E1 sealed at both ends to reach the triplet commutation function, simple in structure, commutation is reliable; Do sky in the middle of the main valve plug E1 and process a pressure release valve port D4 at the end face of safety relief valve direction, pressure release valve port D4 is communicated with the inner chamber of main valve plug, also directly communicates with water intake 1; Main valve plug E1 has played the triple functions of threeway sealing commutation, Decompression valves valve port and flow pass.Carry safety relief valve D in the three-way diverter valve, the default elastic force size of safety relief valve D is by pressure release spring D2 decision, and pressure release valve port D4 size is relevant with the pressure release spring force, precise control; And be connected with the Returnning spring E6 of return action on the main valve plug E1, pressure release spring D2 and Returnning spring E6 independently open fully, can get required separately elasticity coefficient respectively, reliability and the not high defective of Security in the time of can avoiding existing bypass spring to hold concurrently pressure release and the two function of answer.
First working state: as shown in Figure 2, linear electric motor are when being returned to the end, and under Returnning spring E6 effect, main valve plug right-hand member and primary sealing area B sealing make water intake 1 communicate with bypass outlet 3, and main water outlet 2 disconnects; Pressure releasing valve core D1 among the safety relief valve D with main valve stem E3 telemechanical to the right, vacates bigger circulation section in advance and guarantees that water intake 1 and bypass export 3 and communicate the dependable flow size fully under the effect of pressure release spring D2.
Second working state: as shown in Figure 3, linear electric motor are when being pushed to the end, and main valve plug E1 left end and primary sealing area B seal, and water intake 1 communicates with main water outlet 2, and bypass outlet 3 disconnects; Safety relief spool D1 moves to left with main valve stem E3, and the pressure release spring D2 of safety relief valve is pressed onto the working position of requirement.Under this state, when load was stopped up, pressure raise in water intake 1 and the passage that main water outlet 2 communicates, is the proper functioning that guarantees whole system, safety relief valve D overcomes the pressure release spring pressure medium is overflowed a part from bypass outlet 3, reaches safe and reliable work purpose.
Seal by y-type seal ring C between main valve stem E3 and the end cap.Under the situation of y-type seal ring C wearing and tearing, because external and internal pressure has difference, interior pressure effect makes y-shaped ring C to main valve stem center tensioner, the effect of automatic compensation is arranged, compare with the mode that only adopts O-ring seals to seal uncompensated effect in the past, sealing effect is better, and the long journey reliability improves, and valve increases working life.
