Below with reference to accompanying drawing, describe in detail according to selector valve of the present utility model.
First to it should be noted that, in order realizing, to clean respectively the impeller of range hood and the object of oil network, two-way jet pipe need to be set, and the purging system of range hood comprises water tank, the water pump that is used for drawing water, be used for producing the steam generator of steam and/or hot water.If make two-way jet pipe connect respectively purging system, complex structure, increases cost.Therefore, the utility model is by providing a kind of selector valve to simplify the structure of range hood purging system.
As shown in Figures 1 to 5, according to selector valve of the present utility model, comprising: valve body 10, spool 20, connecting tube 30 and coil 40.
Specifically, valve body 10 has the first pipeline section 101, the second pipeline section 102 and the 3rd pipeline section 103.Wherein, under the first pipeline section 101, upper (as shown in Figure 1 top) end of (as shown in Figure 1 below) end and the 3rd pipeline section 103 is communicated with, and the right side of the second pipeline section 102 (right-hand as shown in Figure 1) held and be communicated with the lower end of the first pipeline section 101 and the upper end of the 3rd pipeline section 103 respectively.
Spool 20 is located in the second pipeline section 102 movably.
The right side of connecting tube 30 (right-hand as shown in Figure 1) end is removably connected with the left end of the second pipeline section 102.For example, the left end of the second pipeline section 102 has the first internal thread, and the right-hand member of connecting tube 30 has first outside thread suitable with described the first internal thread, and both are threaded.
As shown in Fig. 1 to 2, when coil 40 power-off, the upper end of spool 20 sealing the 3rd pipeline sections 103.As shown in Figure 3, when coil 40 energising, the right-hand member of spool 20 sealing connecting tubes 30.
Here it should be noted that, coil 40 is connected with spool 20, refers to and adopts electromagnetic induction to be connected between the two.As shown in Fig. 1 to 2, when coil 40 power-off, coil 40 does not generate an electromagnetic field, can be to spool 20 generation effects, and spool 20 is in original state.That is, now the upper end of spool 20 sealing the 3rd pipeline sections 103, makes the first pipeline section 101 be communicated with the second pipeline section 102 to disconnect the 3rd pipeline section 103, and then is communicated with connecting tube 30 by the second pipeline section 102.As shown in Figs. 3-4, when coil 40 energising, coil 40 generates an electromagnetic field, so that spool 20 is moved to the left from above-mentioned original state under the effect of electromagnetic induction, the right-hand member of final spool 20 sealing connecting tubes 30, makes the first pipeline section 101 be communicated with the 3rd pipeline section 103 to disconnect the second pipeline section 102.
According to selector valve of the present utility model, by coil, control spool and move to switch, simple in structure, switch reliable.
According to an example of the present utility model, described selector valve also comprises the elastic component 50 such as spring.Elastic component 50 is arranged in the second pipeline section 102 and between spool 20 and connecting tube 30.When coil 40 power-off, elastic component 50 promotes spool 20 to seal the upper end of the 3rd pipeline section 103, when coil 40 energising, spool 20 moves in interior past connecting tube 30 directions of the second pipeline section 102, the elastic component 50 that compression is connected with spool 20 simultaneously, elastic component 50 is shunk, until the right-hand member of spool 20 sealing connecting tubes 30.
In other words, as depicted in figs. 1 and 2, when coil 40 is during in off-position, elastic component 50 promotes the upper end that spools 20 move right to seal the 3rd pipeline section 103.That is to say, conducting the first pipeline section 101 and the second pipeline section 102, and disconnect the 3rd pipeline section 103.
As shown in Figure 3 and Figure 4, when coil 40 is during in "on" position, spool 20 is moved to the left to seal the right-hand member of connecting tube 30 under the control of coil 40, and spool 20 is by elastic component 50 compressions simultaneously.That is to say, conducting the first pipeline section 101 and the 3rd pipeline section 103, and disconnect the second pipeline section 102.
As shown in Figure 5, according to an example of the present utility model, on the outer wall of spool 20, have along the right-hand member of its axially extended groove 201 and spool 20 and be provided with sealing gasket 202.Thus, groove 201 can further increase the ducting capacity of the second pipeline section 102, and sealing gasket 202 can increase the sealing of 20 pairs of the 3rd pipeline sections 103 of spool.
As shown in figures 1 and 3, according to an example of the present utility model, described selector valve also comprises joint 60, the dismountable upper end that is arranged on the first pipeline section 101 of joint 60.For example, have the second internal thread on joint 60, the upper end of the first pipeline section 101 has second outside thread suitable with described the second internal thread, and both are threaded.Thus, can be connected with the pipeline of purging system by joint 60.
Range hood adopts according to after selector valve of the present utility model, can control respectively the break-make of two-way jet pipe, and then realizes the object of cleaning respectively impeller and oil network, has expanded clean range.
In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiments or example.
Although illustrated and described embodiment of the present utility model above, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can change above-described embodiment in the situation that not departing from principle of the present utility model and aim in scope of the present utility model, modification, replacement and modification.
