Problems solved by technology

[0002] When flow distribution is required, two adjustment interlocking forms can generally be used, but this form may have inconsistent adjustment flow or inconsistent adjustment of the opening of the two valves, and the flow cannot be adjusted more accurately
[0003] Moreover, the general-purpose three-way flow distribution valve generally has a small caliber and a low pressure. Using it in a high-pressure state will result in laborious adjustment or pressure jamming

Embodiment Construction

[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0019] Such as figure 1 , 3 As shown in , 4, a three-way flow distribution valve includes a valve body 1, a valve cover 2, a valve stem 3 and a valve core 8, the valve body 1 is provided with a cavity 4, and the valve cover 2 is connected with the valve body 1 for To close the upper port of the cavity 4; the valve body 1 is also provided with an A port channel 5, a B port channel 6 and a P port channel 7, the A port channel 5 communicates with the upper part of the cavity 4, and the B port channel 6 communicates with the cavity. The lower part of the cavity 4 communicates, and the port P channel 7 communicates with the lower port of the cavity 4 . Such as Figure 4 As shown, the lower part of the cavity 4 is provided with a lo...

Abstract

The invention discloses a three-way flow distribution valve. The three-way flow distribution valve comprises a valve body, a valve deck and a valve rod. The valve deck is connected with the valve bodyand used for closing an upper port of a cavity of the valve body. The valve body is further provided with a port A channel, a port B channel and a port P channel. The port A channel communicates withthe upper portion of the cavity. The port B channel communicates with the lower portion of the cavity. The port P channel communicates with the cavity. The valve rod penetrates through the valve deckand is connected with a valve element arranged in the cavity. The valve element moves up and down to control the amount of a medium getting into the port A channel and the port B channel. The valve deck is provided with a balance piston cavity. Through the three-way flow distribution valve, the condition of non-uniformity of flow regulation is avoided; a balance mechanism is added so that the flow can be rapidly and conveniently adjusted under the high-pressure condition.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a three-way flow distribution valve. Background technique [0002] When flow distribution is required, generally two adjustment interlocking forms can be used, but this form may have inconsistent adjustment flow or inconsistent adjustment of the opening of the two valves, and the flow cannot be adjusted more accurately. [0003] Moreover, the general-purpose three-way flow distribution valve generally has a small caliber and a low pressure. Using it under high pressure will result in laborious adjustment or pressure jamming. Contents of the invention [0004] In order to solve the above problems, the present invention proposes a three-way flow distribution valve. [0005] Specifically, a three-way flow distribution valve includes a valve body, a valve cover and a valve stem. Channel, B port channel and P port channel, the A port channel communicates with the upper part of the ...
