Embodiment
A kind of embodiment of two-bit triplet reversing globe valve is as shown in Fig. 1 ~ 4: comprise valve body 21, valve body is rotatably equipped with the spool 20 that rotation axis extends along the vertical direction, spool comprises body, body comprises the first cylindrical portion, spherical portion 8 and the second cylindrical portion that order is up and down arranged, the upper end of the first cylindrical portion is connected with handle by square shaft 1, first cylindrical portion coordinates with end cap 5 rotary seal on valve body, and the second cylindrical portion coordinates with valve body rotary seal.Valve body is provided with the first gas port 14, second gas port 15 and the 3rd gas port 16, second gas port 15 is positioned at the downside of spool 20, first gas port 14, the 3rd gas port 16 lay respectively at the left and right sides of spool, the lower end surface of valve body is a plane, and the first gas port is all arranged on the lower end surface of valve body away from one end of spool away from one end of spool, the 3rd gas port away from one end of spool, the second gas port.Spool has shutoff second gas port in rotation process, conducting first, first working position of the 3rd gas port and shutoff first gas port, conducting second, second working position of the 3rd gas port, the body of spool is provided with the first passage 18 that the second channel 17 that extends along the vertical direction is vertical with above-below direction with bearing of trend, first passage 18, second channel 17 is straight passage, first passage 18 is for realizing the first gas port 14 when spool is in the first working position, 3rd gas port 16 conducting, second channel 17 is for realizing the second gas port 15 when spool is in the second working position, 3rd gas port 16 conducting, the lower end of spool has spool plane, valve body is provided with the valve body plane 19 for coordinating with spool plane sealing in the downside of spool plane, the upper end-hole of the second gas port 15 to be arranged in valve body plane and with the rotation axis eccentric setting of spool, the upper channel mouth of second channel 17 is arranged on the conduit wall of first passage 18, second channel 17 have be arranged in spool plane with when spool is in the first working position and the upper end-hole of the second gas port stagger, the lower channel opening be communicated with the second gas port when spool is in the second working position, the lower channel opening of second channel and the rotation axis eccentric setting of spool, spool has been peripherally installed with seal ring 10 in the lower channel opening of second channel, being sealed and matched between spool plane and valve body plane can be realized by seal ring.The opposing both sides of the spherical portion of spool are provided with frustal plane 22, the passway, two ends of first passage 18 is arranged on corresponding frustal plane respectively, and frustal plane 22 is communicated with the communication gap 23 of the 3rd gas port and first passage 18 when spool is in the second working position with being formed between valve body.One end that first gas port closes on spool is provided with for coordinating with the spherical portion ball face sealing of spool with the valve base 11 of shutoff first gas port when spool is in the second working position, and valve base is made up of rubber material.Figure middle term 12 represents lead sealing; Item 2,3 all represents back-up ring; Item 4 represents locating studs; Item 6,7 and 13 all represents O-ring seals.
The using process of this two-bit triplet selector valve is: when needs first gas port, the 3rd gas port conducting, rotational valve core to the first working position, first passage conducting first gas port, the 3rd gas port, now the lower channel opening of second channel and the upper end-hole of the second gas port stagger mutually, by the seal action of seal ring, gas can not enter the second gas port through second channel, and therefore the second gas port is by shutoff; When needs second gas port, the 3rd gas port conducting, rotational valve core to the second working position, valve base coordinates with spherical portion ball face sealing, first passage is by shutoff, now the lower channel opening of second channel is communicated with the upper end-hole of the second gas port, gas enters first passage through the gap between frustal plane and valve body, then enters the second gas port through second channel.Being in the first working position at spool is adopt plane sealing structure to carry out shutoff to the second gas port, greatly reduce the making accuracy requirement of spool and valve body, and then reduce the fabricating cost of product, be easy to batch process make, simultaneously plane sealing can also ensure the reliable sealing characteristic of product, this product is compared be applicable to the rail vehicle worked in harsh environments; The upper channel mouth of second channel is arranged on the conduit wall of first passage, make second channel can be the straight passage extended along the vertical direction, second channel is facilitated to process like this, the outer circumferential face of spherical portion and valve body are no longer complete mating spherical surfaces, valve body only needs to process straight valve pocket, and the making of valve body is quite simple; First, second, third gas port is all arranged on the lower end surface of valve body away from one end of spool, is so conveniently installed on other parts valve body to realize the connection of pipeline; Valve base is soft sealing structure, can ensure sealing effect, has certain compensating action to the wearing and tearing of part simultaneously.
In other embodiment of this two-bit triplet reversing globe valve: seal ring also can not be established, now spool plane can directly contact with valve body plane the shutoff sealed to realize when spool is in the first working position to the second gas port; The upper channel mouth of second channel also can not be arranged on the conduit wall of first passage, such as is arranged on the outer circumferential face of spool, and now frustal plane and the communication gap between frustal plane and valve body all can not be established; Second channel and first passage may not be straight passage, such as having the angled channel at turning; Valve base also can not be established, and now the outer circumferential face of spherical portion can realize spool shutoff first gas port when the second working position by being sealed and matched with valve body sphere.
The embodiment of spool is as shown in Fig. 1 ~ 4: the concrete structure of spool is identical with the spool described in above-mentioned each two-bit triplet reversing globe valve embodiment, is not described in detail in this.
