Abstract
This utility model relates to a valve, especially an anti-block reversal valve in the conveying line that the liquid materials contain particle or mixed material of solid and liquid, this valve includes a valve body, a valve spool and a valve stem; the valve spool is inserted in valve body and forms circular rotated matching with the valve body; the circular side of valve body is provided with four through holes any two of which are vertical to each other, and the axial line of through hole is vertical to axial direction of valve body; the valve spool is equipped with two channels, 90 degrees angle is between two ports of each channel, the total four ports of two channels are relatively connected with four through holes on valve body. After the two relative through holes of this valve are connected with the pump, one of the other two relative through holes is an inlet of valve, the other is an outlet of valve; after the valve spool rotates 90 degrees, the previous inlet of valve will be changed to the outlet, and the previous outlet will be changed to the inlet, so as to implement reversing; the structure is simple and the operation is convenient.
Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of liquid material that is applicable to conveying contains the anti-plugging selector valve in the conveyor line of particle and solid, liquid mixed material.
Background technique
In the production process that product is made, because the purposes difference, a kind of material not only may carry out on same equipment repeatedly that positive and negative direction is carried but also may be also to other local conveying by pump.In order to finish this kind function, normally at inlet and delivery side of pump place configuration several valves and many pipelines of pump, this is the pipe arrangement complexity not only, and because elbow of pipeline and valve form the resistance increase, rate of flow of fluid is slack-off, and solid particle is deposited in before the pump and behind the pump, causes pipeline blockage.
Summary of the invention
The purpose of this utility model is to solve to need that a plurality of valves are set in above-mentioned and the sucker elbow is realized the deficiency of fluid reversing, and provides a kind of simple in structure, can realize the anti-plugging selector valve that commutates easily.
The purpose of this utility model is achieved by the following technical solution: a kind of anti-plugging selector valve, it is characterized in that: this valve includes valve body, spool and valve rod, described valve core housing is inserted in the valve body and with valve body and constitutes circumferential rotatable the cooperation, be provided with four in all sides of valve body and become 90 ° port between adjacent, the axis of port is axially vertical mutually with valve body, on spool, be provided with two passes, be mutually 90 ° between the two-port of every passage, totally four ports of two passages respectively with valve body on four relative connections of port.
The utility model further is set to: described valve body is a ring, and described spool is a disc, and the disc valve core housing is inserted in the endoporus of annulus valve body, and each closely is sealed with capping in the upper and lower both sides of valve body.
Respectively be provided with the convenient joint that is connected with pipeline on the described port.
The upper end of described valve rod is provided with the pneumatic actuating device that orders about the valve rod rotation.
The beneficial effects of the utility model are: with the two relative ports of this valve with after pump is connected, another is the import of valve to relative port one, another is the outlet of valve, behind the spool half-twist, then the original import of valve becomes outlet, and outlet becomes import, thereby has realized commutation, simple in structure, easy to operate.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
Extremely as can be known shown in Figure 3 by Fig. 1, the embodiment of a kind of anti-plugging selector valve of the utility model, include valve body 2, spool 6 and valve rod 8, described spool 6 covers are inserted in the valve body 2 and with valve body 2 and constitute circumferential rotatable the cooperation, be provided with four in all sides of valve body 2 and become 90 ° port 21 between adjacent, usually respectively be provided with the convenient joint 22a that is connected with pipeline on the port, 22b, 22c, 22d, the axis of port 21 is axially vertical mutually with valve body 2, on spool 6, be provided with two passes 61a, 61b, the two-port 611 of every passage 61, be mutually 90 ° between 612, two passage 61a, totally four port 611a of 61b, 611b, 611c, 611d respectively with valve body on four port 21a, 21b, 21c, 21d is communicated with relatively.With two opposing tabs 22a, the 22c of this valve with after pump is connected, another is the import of valve to relative joint one 22b, another 22d is the outlet of valve, and behind the spool half-twist, then the original import 22b of valve becomes outlet, outlet 22d becomes import, thereby realized the commutation of fluid, simple in structure, easy to operate, the commutation function that valve has promptly been realized needing a plurality of valves and a plurality of elbow of pipeline to realize in the past is difficult for stopping up.
In above-mentioned, described valve body 2 is a ring, and described spool 6 is a disc, and disc spool 6 covers are inserted in the endoporus 23 of annulus valve body 2, and each closely is sealed with capping 1,6 in the upper and lower both sides of valve body 2.Certainly, spool also can be sphere, and it is spherical that the inner chamber of valve body should be mutually, but spherical spool and body cavity difficulty of processing are bigger.The outside of valve body is not cylindrical yet in addition, also can be for square etc., but the inner chamber of valve body must be the solid of rotation die cavity, corresponding valve body core also must be solid of rotation (cylindrical or ball valve), just can make the spool rotation.
In this example, valve rod is a pneumatic drive, promptly is provided with the pneumatic actuating device 9 that orders about valve rod 8 rotation in the upper end of valve rod 8, can certainly be for manually, and perhaps hydraulic driving.
