Description
Technical field
The utility model relates to the valve be arranged on bottom tomography devices, particularly relates to a kind of top extending type two channel valve be arranged in tomography devices.
Background technique
At present, chromatographic technique is widely used in chemical industry, food and field of biological pharmacy as the technology of separating substances purifying.Tomography devices is the key equipment of chromatographic technique application, usually need to load solid-phase adsorbent in tomography devices, during chromatographic runs, material containing material to be separated enters tomography devices, material to be separated is by adsorbent, the material do not adsorbed, through sorbent, through the screen cloth of equipment bottom, is discharged from device bottom.Then get off by the material elutes adsorbed with eluent, finally regeneration process is carried out to sorbent and enter next cycling.When sorbent changed by needs, need the end cap of equipment to open and could take out, operate very inconvenient.Chemical industry equipment there are top extending type and bottom open type tank bottom valve, because valve is for only having a passage, discharging liquid when can not meet chromatography normal running and retain solid-phase adsorbent.
Existing valve is adopted to there is following problems: 1, single channel valve can not realize the discharge respectively of liquid (loading material, wash water, eluent, regenerated liquid) and sorbent; 2, upper exhibition multi-channel reversing valve and chemical industry equipment used or bottom open type valve can not realize the discharge respectively of liquid and sorbent; There is complex structure in 3, can realize that sorbent and liquid discharges respectively two logical or triple valves, it is inconvenient to install, with the shortcoming such as the sealing of screen cloth is unreliable.
Model utility content
The purpose of this utility model is the problems referred to above overcoming prior art existence, proposes a kind of top extending type two channel valve.The utility model passes through runner and the seal form of particular design, solves the problem that in tomography devices, sorbent is discharged, solves the sealing between lower screen and valve, throttle down simultaneously, liquid in chromatography course of normal operation is discharged separately; Open valve, sorbent can be discharged by valve passage.
The utility model realizes by the following technical solutions:
A kind of top extending type two channel valve, it is characterized in that: comprise valve body, valve seat and elbow', one end of described elbow' is arranged in valve body, the other end of elbow' is output terminal, described valve seat embeds in the turn of bilge of elbow', described valve body is provided with fluid passage I and at least one fluid passage II, described fluid passage I and fluid passage II mutually through, described elbow' and the corresponding position of fluid passage II offer the hole be communicated with fluid passage II, described fluid passage I is all communicated with elbow' with fluid passage II, also comprise construction of switch, described construction of switch comprises lifting bar, handwheel and the sealed cap for fluid-encapsulated passage I, described sealed cap is arranged on fluid passage I, described valve seat is provided with valve seat through-hole, described handwheel is arranged on one end of lifting bar, the other end of lifting bar is successively through valve seat through-hole, behind elbow' and fluid passage I and sealed cap fix, handwheel drives opening or closing of sealed cap elevating control fluid passage I by lifting bar.
Described fluid passage II is multiple, and multiple fluid passage II is along the circumferential direction evenly distributed on valve body.
Be provided with groove in described valve seat through-hole, in groove, down has Sealing.
Described valve seat through-hole and lifting bar screw-thread fit.
The sealed end of described fluid passage I is concave surface.
Described sealed cap has groove, and in groove, down has Sealing.
Described construction of switch also comprises lock screw, and described sealed cap is fixed by lock screw and lifting bar.
