Description
Technical field
The utility model relates to valve technology field, particularly a kind of stopcock with switching function between multiport.
Background technique
Stopcock is a kind of throughway valve of snap switch, move with wiping action, and can prevent the contact with flowing medium when standard-sized sheet completely, therefore it also can be used for the medium with suspended particulate usually owing to revolving between sealing surface.Another key property of stopcock is that it is easy to adapt to multi-channel structure, so that a valve can obtain two, three, even four different runners.The design of pipe-line system can be simplified like this, reduce some connection fittings needed in valve consumption and equipment.
Many logical stopcocks have multiple port, the port of how logical stopcock conventional on the market is generally arranged along cock axes normal direction, such as some three way cock, two side ports lay respectively at the both sides of a middle port, due to this set, middle port can only be communicated with in the middle of two side ports by the structure of cock respectively, can not be interconnected between two side ports.Therefore may can increase pipeline equipment when being applied in use occasion, bring cost increase.
Therefore, be necessary to provide a kind of new stopcock structure to solve the problems referred to above.
Model utility content
Main purpose of the present utility model is to provide a kind of stopcock with switching function between multiport.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of many logical stopcocks, comprise the valve body with cavity, there is the cock in shank and tapering and described tapering is accommodated in the valve gap in described cavity, the tapering of described cock has the conical surface and bottom surface, mutual disconnected first passage and second channel is provided with in described tapering, described first passage is from penetrating described tapering perpendicular to described cock axial direction and two outlet is all positioned at the described conical surface, described second channel is oblique penetrates described tapering and two outlet lays respectively in the described conical surface and in described bottom surface.
Concrete, be provided with in described valve body be communicated with described cavity to port and some side ports, described opposition position port being positioned to described cavity exit, described side port is located at described to port side.
Further, be provided with flange outside described side port, described flange is provided with scaffold towards described valve gap direction, described scaffold offers not through the mounting hole of described flange.
Further, described side port has 2-4.
Concrete, described shank is provided with turning handle.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: by being provided with twin-channel cock, makes it in 180 ° of angle ranges, just can regulate the switching between two of leading between each port of stopcock more.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As Fig. 1, shown in Fig. 3 and Fig. 5, the how logical stopcock of one of the present utility model, comprise the valve body 1 with cavity 11, there is the cock 2 in shank 21 and tapering 22, the turning handle 4 tapering 22 being accommodated in the valve gap 3 in cavity 11 and being installed on shank 21, be provided with in valve body 1 be communicated with cavity 11 to port 121, first side port 122 and the second side port 123, port 121 is positioned to the opposition position of cavity 11 outlet, first side port 122 and the second side port 123 are divided into port 121 both sides, first flange 131 is provided with to port 121 outer vent, first side port 122 outer vent is provided with the second flange 132, second side port 123 outer vent is provided with three-flange edge 133, be connected with the first joint 141 between first flange 131 with the second flange 132, first flange 131 is connected with the second joint 142 with between three-flange edge 133.Three flange (131,132,133) are connected to each other by two joints (141,142), and valve outlet structure is supported mutually, sound construction, not easily creep, extend the working life of valve.
As shown in Figure 4, the second flange 132 and three-flange edge 133 are provided with a pair scaffold 15 towards valve gap 3 direction, each scaffold 15 offer not through the mounting hole 151 of flange (132,133).Can be directly fixed on scaffold 15 when being also provided with complicated driving mechanism above stopcock, valve gap 3 position is not affected when driving mechanism is by fixing through the fixed block of mounting hole 151, also do not affect the agent structure of flange (132,133), location is convenient and firm; Even if scaffold 15 brings flange (132,133) to bear a heavy burden, valve body 1 structure also not easily creep under the reinforcing of joint (141,142).
As shown in Figure 5, the tapering 22 of cock 2 has the conical surface 221 and bottom surface 222, mutual disconnected first passage 223 and second channel 224 is provided with in tapering 22, first passage 223 is from penetrating tapering 22 perpendicular to cock 2 axial direction and two outlet is all positioned at the conical surface 221, and second channel 224 is oblique penetrates tapering 22 and two outlet lays respectively in the conical surface 221 and in bottom surface 222.This cock 2 can coordinate existence one port 121 to be positioned at the stopcock valve body 1 of cavity 11 outlet opposition position, makes valve body 1 realize multichannel conversion function.
As shown in Figure 1 to Figure 3, when turning handle 4 turns to the first using state, the second channel 223 of cock 2 is communicated with port 121 and the first side port 122, can realize flow of fluid between port 121 and the first side port 122; When turning handle 4 turns to the second using state, the first passage 223 of cock 2 is communicated with the first side port 122 and can realizes flow of fluid between the second side port 123, first side port 122 and the second side port 123; When turning handle 4 turns to the 3rd using state, the second channel 223 of cock 2 is communicated with port 121 and the second side port 123, can realize flow of fluid between port 121 and the second side port 123.This cock 2 just can regulate the switching between two between each port of threeway plug valve in 180 ° of angle ranges like this.
Above-described is only mode of executions more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
