Description

A kind of Novel threaded plug-in type triple valve

Technical field

The utility model relates to the triple valve field, is specially a kind of Novel threaded plug-in type triple valve.

Background technique

At present, the T-shaped ball valve of common threeway on the market, can realize the basic switching port function in the triple valve, but the connectivity of three ports is relatively poor, especially the port that does not combine with the SF6 density monitor, and adopt the separately design of connecting port and valve body, cause its poor in processability, complex structure, unsuitable field-strip; In actual use, mostly need to be connected with other pipe joints cooperations, owing to cooperate other pipe joint criteria of right and wrong parts that connected, need to carry out customized according to the requirement of self, will greatly increase cost, in particular for the triple valve of SF6 density monitor, demand is large, actual uses the mounting point variation many, and the T-shaped ball valve of existing threeway can't satisfy the needs of actual use at all.

The model utility content

The technical problem that the utility model solves is to provide a kind of Novel threaded plug-in type triple valve, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

A kind of Novel threaded plug-in type triple valve, comprise valve body, control spanner, its valve body is integrated, and valve body is provided with three ports, respectively A port, B port, P port, be provided with seal ring in three ports, be provided with outer-hexagonal outward, the outer-hexagonal lower end is provided with outside thread, the outside thread lower end surface is provided with boss, the outside thread lower end surface cooperates boss that all kinds of plug-in units are installed, and the P port comes source port to be connected by connecting thread and medium, is provided with internal thread in A port and the B port and disposes all kinds of plug-in units; Be provided with spool and three passages in the valve body, spool has intercommunicating pore, and the outside is provided with valve core seal ring, and three passages connect by intercommunicating pore and spool; The control spanner is installed on the spool, shown in the arrow on the control spanner, pulls up and down to realize different break-make operating modes.

In the utility model, described spool is cylindrical body.

In the utility model, described control spanner is installed on the spool by locking nut.

In the utility model, described A port and all kinds of plug-in units of B port arrangement comprise SF6 density monitor, equipment pipe and plug etc.

In the utility model, by adjusting the control spanner, control spool passage switching state, and then detection is finished in the another port when finishing a port fed sheet of a media; Again adjust control spanner spool, close P port medium and come source channels, finish one way ports and detect; When P port medium comes source channels to connect the B port, if the B port connects the SF6 density monitor, then only medium is detected, do not carry to the A port; If the B port is taken over the road, then only to B port fed sheet of a media, do not detect, reduce the utilization rate to the SF6 density monitor, increase the service life.

Beneficial effect: the utility model valve body adopts integral structure, and sealability is excellent, and is by pulling the control spanner, to realize different break-make operating modes, easy to operate; Port adopts the standard piece structure, has reduced cost of production, and all kinds of Sealings of port arrangement are finished medium transport and detection and unidirectional detection and conveying simultaneously, effectively increase the service life.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of Novel threaded plug-in type triple valve of Fig. 6 comprises A port intercommunicating pore 1, B port intercommunicating pore 2, P port intercommunicating pore 3, control spanner 4, A port outer-hexagonal 5, locking nut 6, scabble opposite side 7, P port outer-hexagonal 8, P port connecting thread 9, B port outer-hexagonal 10, valve body 11, plug 12, A port internal thread 13, A port sealing circle 14, A port subchannel 15, valve core seal ring 16, spool 17, P port medium comes source channels 18, P port sealing circle 19, B port sealing circle 20, B port internal thread 21, SF6 density monitor 22, B port subchannel 23, equipment pipe 24.

In the present embodiment, valve body 11 is integrated casting, and P port outer-hexagonal 8, A port outer-hexagonal 5 and B port outer-hexagonal 10 are used for installing fastening; A port internal thread 13 and B port internal thread 21 are the machining moulding, are used for connecting SF6 density monitor 22, external equipment pipeline 24 or plug 12, and P port connecting thread 9 is used for the installation of valve body 11 and pipeline fork offtake or block joint and supports fastening; A port sealing circle 14, B port sealing circle 20 and P port sealing circle 19 are installed on respectively the bottom end of A port internal thread 13, B port internal thread 21 and P port connecting thread 9; Control spanner 4 is installed on the spool 17 by locking nut 6, and by scabbling opposite side 7 transferring power to spool 17; The P port medium of valve body 11 interior settings comes source channels 18 with the control mouth of medium transfer to spool 17, and spool 17 distributes as required, is sent to respectively A port, B port through A port subchannel 15 and B port subchannel 23; Valve core seal ring 16 interference are compressed in the valve body 11, and spool 17 and valve core seal ring 16 are adjacent to cooperation, guarantee sealing reliability, and spool 17 can change the flow direction of medium in valve core seal ring 16 interior rotations, and valve core seal ring 16 relative valve bodies 11 are static; SF6 density monitor 22 can be according to the needs that surrounding space environment is installed, be contained in A port or B port, vacant A port or B port be available plug 12 sealings according to actual needs, prevent that medium leaks when rotation control spanner 4, also can install to connect other equipment pipes 24.

When control spanner 4 mediated as shown in Figure 1, spool 17 passage switching states were finished detection at A port in B port fed sheet of a media as shown in Figure 4, and A port intercommunicating pore 1, B port intercommunicating pore 2 are opened at this moment; When control spanner 4 is rotated down 90 when spending, spool 11 passage switching states are closed P port medium and are come source channels 18 as shown in Figure 5, and P port intercommunicating pore 3 is closed, and SF6 density monitor 22 stops to detect or B port medium being detected; When control spanner 4 rotates up 90 when spending, spool 11 passage switching states as shown in Figure 6, P port medium comes source channels 18 to connect the B ports, if the B port connects SF6 density monitor 22, then only medium is detected, and does not carry to the A port, A port intercommunicating pore 1 is closed; If the B port connects equipment pipe 24, then only to B port fed sheet of a media, do not detect, B port intercommunicating pore 2 is opened, and reduces the utilization rate to SF6 density monitor 22, increases the service life.
