Embodiment 1

[0037] Embodiment one is basically as attached figure 1 shown:

[0038] A one-way three-way valve, comprising a valve body 1, a housing 12 and a heater, the heater adopts a columnar heating rod 13, and the housing 12 is sleeved on the valve body 1 (the housing 12 is divided into two parts, front and rear, and two The two parts are connected by buckles, and the front and rear parts form a snap connection after being set on the valve body 1), and a storage slot is opened on the housing 12, and the heating rod 13 is located in the storage slot, and a fixing device is installed on the opening position of the storage slot. Part 14, the fixing part 14 is a plastic part, and the fixing part 14 is provided with an escape hole for the electric wire of the heating rod 13 to pass through, and the fixing part 14 is interference fit on the storage groove.

[0039] The number of heating rods 13 is three, and each valve port 2 of the one-way three-way valve is equipped with a heating rod 13...

Embodiment 2

[0048] Embodiment 2 On the basis of Embodiment 1, the following improvements have been made:

[0049] combine figure 2 , the valve port 2 on the left side of the one-way three-way valve is also connected with a connecting seat 111 (the connecting seat 111 and the valve body 1 are also integrally formed), and a spring 4 is also installed in the connecting seat 111, and the left end of the spring 4 is fixedly connected with a The plug 6 and the elastic force of the spring 4 can make the plug 6 block the through hole of the connecting seat 111 .

[0050] By adding a connecting seat 111, a plug 6, and a spring 4 on the left valve port 2 of the one-way three-way valve, the left valve port 2 can only be used as a fluid inlet, and the fluid can only flow in from the left valve port 2. Then the one-way flow function of the one-way three-way valve is satisfied.

[0051] In addition, if the valve port 2 on the left side of the one-way three-way valve is not used as a fluid inlet, suc...

Embodiment 3

[0054] Embodiment three is basically as image 3 and Figure 4 As shown, embodiment three has carried out following improvement on the basis of embodiment one:

[0055] It also includes an external thermostat and a relay. The housing 12 is also provided with a temperature sensor 15. The temperature sensor 15 is electrically connected to the input end of the thermostat, and the output end of the thermostat is electrically connected to the input end of the relay. It is electrically connected to the heating rod 13; the thermostat is used to disconnect the temperature controller control relay when the temperature sensor 15 detects that the temperature of the heating rod 13 exceeds 43°C, so that the heating rod 13 stops heating, and when the temperature sensor 15 detects heating When the temperature of the rod 13 is lower than 37° C., the temperature controller controls the relay to be connected, and the heating rod 13 starts heating.

[0056] The temperature sensor 15 adopts a t...

Abstract

The invention relates to the technical field of valves, and particularly discloses a one-way three-way valve which comprises a valve body. Three valve ports are formed in the valve body, a heater is arranged in the circumferential direction of the valve body, and the heater is located outside the valve body. An adjusting unit is arranged on one valve port, serving as a fluid outlet, of the valve body, an adjusting unit comprises a connecting base, a fluid channel communicated with the valve port is formed in the connecting base, and a through hole communicated with the fluid channel is formedin the connecting base. An elastic piece is arranged in the fluid channel, one end of the elastic piece abuts against the valve body, the other end of the elastic piece is connected with a plug capable of plugging the through hole, the other end of the plug abuts against an ejector block, and a communicating channel communicating with the through hole is formed in the ejector block. The one-way three-way valve in the scheme is used for solving the problems that in the prior art, a one-way three-way valve can only achieve the one-inlet two-outlet function and cannot be used as a one-way valve in actual production, and a heater in an existing one-way three-way valve is prone to being damaged.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a one-way three-way valve. Background technique [0002] Directional control valves are currently widely used in industries such as automobiles, oil refining, chemical industry, petroleum, natural gas, food, pharmaceuticals, instrumentation, etc. As more and more directional control valves are used, different types of directional control valves also appear. Such as one-way valve, one-way three-way valve, one-way four-way valve, etc. [0003] Taking the one-way three-way valve as an example, generally only one valve port is used as the fluid inlet, and the other two valve ports are used as the fluid outlet to realize the function of one in and two out; Two outlets are used, but only one of the outlet valve ports is required to have fluid flow, that is, the one-way three-way valve is used as a one-way valve; at this time, the staff generally tightens one of the pipes connected to t...
