Problems solved by technology

This setting of the nozzle position of the four-way valve makes it very inconvenient to install the four-way valve into the system. It is necessary to add elbows to cooperate with the four-way valve, which increases the difficulty of construction and increases the resistance of the pipeline. This installation This method not only increases design and manufacturing costs, but also increases system energy consumption

Embodiment 1

[0036] Such as Figure 1 to Figure 7As shown, a new multifunctional four-way reversing valve includes a valve seat 1 and a valve core 2, the valve seat 1 is cylindrical, the valve seat 1 includes 4 fluid connection ports, and the 4 fluid The connecting ports are horizontally connected with the valve seat 1 and communicated with the inner cavity of the valve seat 1, and the four fluid connection ports include a supply-side inlet 101 and a supply-side outlet 102 for connecting to the main supply-side system. The load-side inlet 103 and the load-side outlet 104 of the user-side system; the valve core 2 is sealed and rotatably assembled in the inner cavity of the valve seat 1, the rotation axis of the valve core 2 is in the up-down direction, and the upper rotation axis of the valve core 2 is provided with a useful At the connection part connected with the driving device, the upper part of the valve seat 1 is fixedly connected to the upper gland 3 by screw one 7, and the lower par...

Embodiment 2

[0048] The difference between this embodiment and embodiment 2 is that the third channel 203 and the fourth channel 204 on the valve core 2 have different structures. Such as Figure 12 As shown, the four passages on the spool 2 include a first passage 201, a second passage 202, a third passage 203 and a fourth passage 204, and the first passage 201 and the second passage 202 are formed by the through-spool 2 diameter straight holes, the first passage 201 is located above the second passage 202 and parallel to the second passage 202, the third passage 203 and the fourth passage 204 are formed by the passages arranged inside the valve core 2 Formed, the hole can be made of pipes, the third channel 203 and the fourth channel 204 are symmetrical to the center of the rotation axis of the valve core 2 .

Abstract

The invention discloses a novel multifunctional four-way reversing valve. The novel multifunctional four-way reversing valve comprises a valve seat and a valve element, wherein the valve seat comprises four fluid connecting ports, the four fluid connecting ports are horizontally connected with the valve seat and communicate with the interior of a valve body, the four fluid connecting ports comprise a supply side inlet, a supply side outlet, a load side inlet and a load side outlet, the supply side inlet and the supply side outlet are used for being connected with a main supply side system, andthe load side inlet and the load side outlet are used for being connected with a user side system; and the valve element is assembled in an inner cavity of the valve seat in a sealed and rotating mode, four channels are formed in the valve element, and when the valve element rotates relative to the valve seat, reversing, blocking and 0-100% flow adjusting functions of the valve are achieved through the valve element and the four fluid connecting ports. The novel multifunctional four-way reversing valve can have the functions of flowing reversing, blocking and controlling or flow adjusting offluids such as gas and liquid in a pipeline, the four-way valve can be conveniently installed on a connecting pipe in a system, the design and manufacturing cost is reduced, and the energy consumptionof the system is also reduced.

Description

technical field [0001] The present invention relates to the technical field of reversing valves, in particular to a flow reversing, flow regulation, blockage valve, which is easy to install and disassemble and is applied to fluid transmission and distribution pipeline systems, heating systems, cooling systems, refrigeration systems, or industrial heat exchangers. And temperature measurement, flow measurement multifunctional four-way reversing valve. Background technique [0002] Backwashing and / or reverse flow is essential for filter and heat exchanger cleaning as well as for specially engineered systems such as heat pumps. These functions are usually performed by so-called four-way valves or four-way cocks. A four-way valve or four-way cock is a fluid control valve with a body having four ports equally spaced around the valve chamber and a spool with two passages connecting adjacent ports. The spool can be cylindrical, conical or spherical. It has two flow positions, the...
