Abstract
The utility model relates to a cam rapid opening and closing valve which is formed by sequentially connecting a cam handle, an ejector pin, a base, a valve base, a valve core and an end cover and is characterized in that threaded holes are respectively formed in left and right ends of the base, the left end of the base is connected with a liquid inflow pipe and the right end of the base is connected with a liquid outflow pipe. When the handle is rotated with the rotating angle being 0-90 degrees, the ejector pin gradually moves upward in the vertical direction, so as to control the valve core to gradually open; and the flow is gradually increased along with the increase of the rotating angle during the process, and the fluid gradually flows in from the port A and flows out from the port B. When the handle is rotated with the rotating angle being 90-180 degrees, the ejector pin gradually moves downward in the vertical direction due to the elastic force action of a small spring, the valve core is gradually closed due to the elastic force action of a large spring; and the flow is gradually decreased along with the increase of the rotating angle, and the port A is finally closed.
Description
Affiliated technical field
The utility model relates to the cam snap switch control valve unit of using on a kind of biological medicine equipment, especially can be fast, safety, easily the flow of the fluid in the system is controlled.
Background technique
At present; The basic structure of known valve mainly comprises the Effector that spool, valve body and driving spool do relative motion in valve body; Realizing driving spool, in valve body, to make the device of relative movement can be spring, electromagnet, and some occasion also adopts hydraulic action to drive.But a lot of biological medicine occasions then require fast, make things convenient for, safe realization is to the control of fluid in the system, and the complex structure of general valve will realize that the control of convection cell is comparatively loaded down with trivial details.And the utility model adopts the cam acceleration switching valve; This device can be fast, safety, adjusting and the control easily flow direction, pressure height and the flow size of fluid in the system expected; Fluid flows uniformly in can the realization system, further satisfies the specific (special) requirements of this occasion of biological medicine equipment.
Summary of the invention
Can not be fast in order to overcome existing valve, safety, the deficiency easily fluid in the system controlled, the utility model provide a kind of cam acceleration switching valve can be fast, safety, adjusting and the control expected of flow direction, pressure height and the flow size of convection cell easily.
The utility model solves the technological scheme that its technical problem adopted: a kind of cam acceleration switching valve; Constitute by cam handle, push rod, matrix, valve seat, spool, end cap; Wherein end has a tapped hole respectively about matrix, and left end connects liquid inlet pipe, and right-hand member connects drain pipe.Be connected with the cam mechanism that push rod and cam are formed in the bottom of matrix, when rotating counterclockwise handle, at corner in the scope of 0 to 90 degree; Cam promotes push rod and moves upward gradually in vertical direction, and the control spool is opened gradually, and the augmented flow along with rotation angle in this process increases gradually; Fluid realizes that flowing into the B mouth gradually from the A mouth flows out; Be connected with spool, valve seat and end cap at the top of matrix, wherein end cap is connected by big spring with spool, when clockwise rotating handle; Push rod is in vertical direction owing to move downward under the resilient force of little spring gradually; Spool is because the resilient force of big spring is closed gradually, and the augmented flow along with rotation angle in this process reduces gradually, final plant closure A mouth.The concrete structure shape is seen Figure of description 4.

Embodiment
Structure erection drawing and Fig. 5 cam acceleration switching valve and liquid inlet and outlet pipe installation diagram according to Fig. 4 cam acceleration switching valve.Cam (2) on matrix, leans on the effect of little spring (11) through finger setting, and push rod (8) keeps contacting all the time with cam (2).Use scyewed joint between end cap (5) and the matrix (3).Because the effect of big spring (6), valve seat (4) contacts with matrix (3), spool (7) and valve seat (4) all the time.The liquid-inlet A of matrix (3), outlet B have internal thread and have externally threaded liquid inlet pipe (12) to be connected with drain pipe (13).Wherein the place of scyewed joint must add sealer and prevents heads.Owing to be used for medical equipment, before using, must carry out disinfection.At first using concentration is the sterilization of 75% medicinal alcohol, and the solution in the reusing system cleans then, reexamines then whether leakage is arranged.Guarantee that sterilization accomplishes and do not have after the leakage, in the connecting system.When corner 0 to 90 the degree scope in, when rotating counterclockwise handle (1), push rod (8) moves upward in vertical direction gradually, control spool (7) open gradually.Augmented flow along with rotation angle in this process increases gradually, and fluid realizes that flowing into the B mouth gradually from the A mouth flows out.When clockwise rotating handle (1), owing to move downward gradually under the resilient force of little spring (11), spool (7) is owing to flow in the resilient force realization system of big spring (6) reduces push rod gradually, and final plant closure in vertical direction.
Claims (2)
1. cam acceleration switching valve, it is to be linked in sequence by cam handle, push rod, matrix, valve seat, spool, end cap, it is characterized in that: the left and right end of matrix has a tapped hole respectively, and left end connects liquid inlet pipe, and right-hand member connects drain pipe.
2. cam acceleration switching valve according to claim 1; It is characterized in that: matrix bottom cam handle through finger setting on matrix; Lean on the effect push rod of little spring to keep contacting all the time with cam; Because the effect valve seat of big spring contacts with matrix, spool and valve seat all the time, use scyewed joint between end cap and the matrix on matrix top, push rod and cam profile surface contact and contact for line.
