As preferably, described spool is made up of silastic material.
As preferably, described inflow valve body right ports is set to taper hole.
As preferably, described set screw is high-head knurling screw.
The beneficial effects of the utility model:
(1) the utility model have rational in infrastructure simple, production cost is low, easy for installation; multiple functional; can effectively solving that metal spring protection is good easily gets rusty, it is easy to produce to pollute, also existing check valve can not carry out the problem that regulates according to the pressure of fluid.
(2) the utility model is provided with set screw, and set screw is high-head knurling screw, it is possible to aspect regulates, thus ensure that result of use.
(3) in the utility model, spring is positioned at spool right ports, ensure that spring does not contact with fluid, thus ensure that spring not easily gets rusty, and it also avoid simultaneously and produces to contact to affect result of use with fluid.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
1-flows into valve body; 2-valve seals; 3-flows out valve body; 4-flow pass; 5-lid body; 6-set screw; 7-set screw; 8-lid body sealing ring; 9-piston; 10-spring; 11-spool; 12-flow channel; 13-filtration unit.
Embodiment:
As shown in Figure 1, this embodiment is by the following technical solutions: a kind of blood purification patient's blood vessel intravenous administration two is led to, and comprises and flows into valve body 1, valve seals 2, flows out valve body 3, flow pass 4, lid body 5, set screw 6, set screw 7, lid body sealing ring 8, piston 9, spring 10, spool 11, flow channel 12 and filtration unit 13; Described inflow valve body 1 is fixedly connected on and flows out valve body 3 upper left side; It is provided with valve seals 2 between described inflow valve body 1 and described outflow valve body 3; Described flow pass 4 is arranged in and flows out valve body 3 lower-side hole; Described lid body 5 is fixedly connected on and flows out valve body 3 upper right side; It is provided with lid body sealing ring 8 on the left of described lid body 5 and between described outflow valve body 3; Described set screw 6 is movably connected in lid body 5 center of inside; Described piston 9 right-hand member is fixedly connected on set screw 6 left end by set screw 7, and described piston 9 outside surface is movably connected in and flows out in valve body 3 upper right side opening; On the right side of described spool 11, outside surface is movably connected in and flows out in valve body 3 right ports, and described spool 11 left end is connected with inflow valve body 1 inner right side hole, is connected with spring 10 in described spool 11 right ports; Described spring 10 right-hand member is connected with piston 9 left end; Described flow channel 12 is arranged in and flows into valve body 1 left hole; Described filtration unit 13 is positioned at flow channel 12 left end, and described filtration unit 13 is fixed on and flows into valve body 1 left end inner openings.
