Abstract
The invention discloses a sleeve type valve. The sleeve type valve comprises a valve body and a valve core, wherein the valve core is arranged in the valve body; the valve body comprises a front valve body and a rear valve body; a liquid cavity is formed inside the rear valve body; the outer wall of the valve core is provided with a liquid cavity baffle ring; the liquid cavity baffle ring of the valve core is positioned in the liquid cavity of the rear valve body and partitions the liquid cavity into an open valve liquid cavity and a close valve liquid cavity; the rear valve body is provided with at least one open valve liquid inlet hole and at least one close valve liquid inlet hole; the open valve liquid inlet hole is communicated with the open valve liquid cavity; and the close valve liquid inlet hole is communicated with the close valve liquid cavity. The sleeve type valve is easy to open and is labor-saving and has long service life.
Description
Technical field
The present invention relates to a kind of valve, specifically a kind of shell type valve that is used for reservoir.
Background technique
Existing Reservoir valve is opened effort, damages easily.
Summary of the invention
The objective of the invention is to design a kind of shell type valve.
What the present invention will solve is existing Reservoir valve, opens effort, easily the problem of damaging.
Technological scheme of the present invention is:
The present invention includes valve body and spool, spool is located in the valve body.Valve body comprises front valve shell and rear valve body, back valve
The body inboard is provided with sap cavity, and the spool outer wall is provided with the sap cavity barrier ring, and the sap cavity barrier ring of spool is positioned at the sap cavity of rear valve body and sap cavity is separated into out the valve sap cavity and closes the valve sap cavity; On rear valve body, be provided with at least one and open valve inlet opening and at least one and close the valve inlet opening, open the valve inlet opening and open the valve sap cavity and be communicated with, close the valve inlet opening and close the valve sap cavity and be communicated with.
Advantage of the present invention is: open simply laborsavingly, service time is long, is particularly suitable for using in the reservoir.
Description of drawings
Fig. 1 is the structural representation under the opening state of the present invention.
Fig. 2 is the structural representation under the closed condition of the present invention.
Fig. 3 is a perspective view of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in the figure, the present invention includes valve body and spool 2, spool 2 is located in the valve body.Valve body comprises front valve shell 1 and rear valve body 3, and rear valve body 3 inboards are provided with sap cavity, and spool 2 outer walls are provided with sap cavity barrier ring 10, and the sap cavity barrier ring 10 of spool 2 is positioned at the sap cavity of rear valve body 3 and sap cavity is separated into out valve sap cavity 9 and closes valve sap cavity 11.Being provided with at least one on rear valve body 3 opens valve inlet opening and at least one and closes the valve inlet opening.The valve inlet opening of opening of present embodiment is two, is respectively out valve inlet opening A and opens valve inlet opening B, opens valve inlet opening A, opens valve inlet opening B and open valve sap cavity 9 to be communicated with.The valve inlet opening that closes of present embodiment is two, is respectively to close valve inlet opening C and close valve inlet opening D, closes valve inlet opening C, closes valve inlet opening D and close valve sap cavity 11 to be communicated with.Opening on valve inlet opening A and the B behind the external liquid-adding device, can realize pressurized liquid injection in opening valve sap cavity 9.Similarly, closing on valve inlet opening C and the D behind the external liquid-adding device, can realize to closing valve sap cavity 11 pressurized liquid injections.
Front valve shell 1 is provided with fluid input 6 and sealing cover body 7, and the inboard of sealing cover body 7 is provided with sealing surface 8.Sealing cover body 7 is the cone seal cover body.
Opening the valve inlet opening and can being one of present embodiment similarly closed the valve inlet opening and also can be one.
Working principle of the present invention is:
When the present invention works, combines with front valve shell 1 sealing surface 8 by spool 2 left ends and to realize sealing, thereby the blocking-up upstream fluid enters passage 12 in the middle of the spool 2 from fluid input 6, this moment valve closing.When opening, behind the external liquid-adding device, by opening valve inlet opening A or/and B pressurized liquid injection in opening valve sap cavity 9 on the rear valve body 3, piston valve core 2 is opened the promotion of fluid pressure in the valve sap cavity 9 and is moved right, make the seal failure of spool 2 and front valve shell sealing surface 8, valve is opened, and upstream fluid enters passage 12 in the middle of the spool 2 from fluid input 6, then flows to the downstream.Open the position that the liquid measure may command spool 2 in the valve sap cavity 9 is opened by control, thereby realize purpose by valve controlling liquid flow.
If want throttle down, behind the external liquid-adding device, or/and D 11 pressurized liquid injections in closing the valve sap cavity promote spool 2 to left movement, and finally withstand the sealing surface 8 of front valve shell 1 by closing valve inlet opening C, realize sealing, valve is closed.
