Abstract
The utility model discloses a multifunctional check valve, including first valve body, set up second valve body and third valve body at the both ends of first valve body respectively, be equipped with the case in the first valve body, the case is connected with the valve rod, intaking of case and first valve body is equipped with the second packing ring between the end, is equipped with first packing ring between the play water end (W. E. ) of case and first valve body, be equipped with the check valve in the second valve body, the end of intaking of check valve moves towards first valve body, one end that first valve body and second valve body are connected is external to have at least one temperature probe jack. This application makes the valve installation in the pipeline more convenient through closing form as an organic whole with the check valve with multi -way valve, also more does benefit to the space requirement of adaptation erecting bed. And this application is still through setting up the temperature probe jack on the lateral wall of first valve body to temperature in to fluid pipeline is monitored.
Description
Technical field
This utility model relates to a kind of multi-functional check valve.
Background technology
When fluid conveyings such as various water deliverys and oil transportations, owing to pipeline in use can need to arrange check valve body because of system, market substantially uses check valve body to add the mode of other valve to control direction and the switch of fluid at present, the installation of multiple valves is often limited by the space of a lot of erecting beies, is not easy to install.
Utility model content
The purpose of this utility model is to provide a kind of multi-functional check valve, the problem being not easy to install to solve existing pipeline to be limited by space.
For solving above-mentioned technical problem, this utility model provides a kind of multi-functional check valve, including the first valve body, is separately positioned on the second valve body and the 3rd valve body at the two ends of the first valve body；Being provided with spool in first valve body, spool connects valve rod；It is provided with the second packing ring between the water inlet end of spool and the first valve body, between the water side of spool and the first valve body, is provided with the first packing ring；Being provided with check valve in second valve body, the water inlet end of check valve is towards the first valve body；It is equipped with at least one temperature probe jack outside one end that first valve body and the second valve body connect.
Further, in the first valve body passes through first, Threaded Connector Coupling and the second valve body connect；In first, Threaded Connector Coupling is fixed on the second valve body, and in first, the other end and first valve body screw thread of Threaded Connector Coupling connect.
Further, the first valve body is connected by Threaded Connector Coupling in nipple and second and the 3rd valve body；One end that first valve body and the 3rd valve body connect is provided with the external screw thread that the female thread with nipple matches；In second, one end of Threaded Connector Coupling is fixed on the 3rd valve body, and in second, the other end of Threaded Connector Coupling is threadeded with nipple.
Further, valve rod is provided with the valve handle being fixed on its top by securing member.
Further, the second valve body is provided with external screw thread away from the inner side of one end of the first valve body.
Further, the 3rd valve body is provided with external screw thread away from the outside of one end of the first valve body.
The beneficial effects of the utility model are: the application is more convenient by check valve and the changeover valve form of being integrated make the valve in pipeline install, and are also more conducive to adapt to the space requirement of erecting bed.Further, the application arranges temperature probe jack also by the sidewall of the first valve body, in order to the temperature of convection cell pipeline is monitored.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model.
Wherein: 1, the first valve body；11, spool；12, valve rod；13, valve handle；14, securing member；15, the first packing ring；16, the second packing ring；2, the second valve body；21, check valve；22, female thread；3, the 3rd valve body；31, external screw thread；4, Threaded Connector Coupling in first；5, nipple；6, Threaded Connector Coupling in second；7, temperature probe jack.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand this utility model; it is to be understood that; this utility model is not limited to the scope of detailed description of the invention; from the point of view of those skilled in the art; as long as various changes limit and in the spirit and scope of the present utility model that determine, these changes are apparent from appended claim, all utilize innovation and creation that this utility model conceives all at the row of protection.
Multi-functional check valve 21 as shown in Figure 1, including the first valve body 1, is separately positioned on second valve body 2 and the 3rd valve body 3 at the two ends of the first valve body 1, is described in detail each valve body separately below:
It is provided with spool 11 in first valve body 1, spool 11 connects valve rod 12, it is provided with the second packing ring 16 between spool 11 and the water inlet end of the first valve body 1, be provided with the first pad between spool 11 and the water side of the first valve body 1, valve rod 12 be provided with by the securing member 14 in securing member 14(the application again be bolt and screw) be fixed on the valve handle 13 at its top.
In second valve body 2 passes through first, Threaded Connector Coupling 4 is connected with the first valve body 1, and the second valve body 2 is provided with external screw thread 31 away from the inner side of one end of the first valve body 1.In first, Threaded Connector Coupling 4 is fixed on the second valve body 2, and in first, the other end and first valve body 1 of Threaded Connector Coupling 4 are threaded.Being provided with check valve 21 in second valve body 2, wherein, the water inlet end of check valve 21 is towards the first valve body 1.Additionally, be equipped with at least one temperature probe jack 7 outside one end of being connected with the second valve body 2 of the first valve body 1, in order to the temperature of convection cell pipeline is monitored.Obviously, the side in temperature probe jack 7 extends into the first valve body 1 herein is to seal, and is opening towards outer one end.
3rd valve body 3 is connected with the first valve body 1 by Threaded Connector Coupling 6 in nipple 5 and second, and the 3rd valve body 3 is provided with external screw thread 31 away from the outside of one end of the first valve body 1.One end that first valve body 1 is connected with the 3rd valve body 3 is provided with the external screw thread that the female thread with nipple 5 matches；In second, one end of Threaded Connector Coupling 6 is fixed on the 3rd valve body 3, and in second, the other end of Threaded Connector Coupling 6 is threadeded with nipple 5.
