Abstract
The utility model relates to a novel sand control valve, which is composed of a locking nut 1, a regulating screw 2, a connecting base 3, a valve body 4, a valve plate 5, a post rod 6, a connecting plate 7, an electric magnetic head 8, a rolling wheel 9, a sand guiding pipe 10, a spring 11, an impedance screw A12, a valve cap 13, a connecting pipe 14, the impedance screw B15, etc. The rectilinear motion of the valve stem of the electric magnetic head is used to push the valve plate 5 to rotate and make the opening and closing of the sand control valve realized. The sand flow is controlled by the impedance screw A12 and the impedance screw B15, and the vacuum degree of the valve body is regulated by the regulating screw 2 and the locking nut 1. The utility model has the advantages of reasonable structure, convenient operation, reliable performance, long service life, etc., and is used for cutting off machines of superhigh pressure water.
Description
The utility model is the sand controlling valve that is used for high-pressure water cutting machine control amount of sand size and open and close.
Domestic existing sand valve, its movement parts that is used to control for the sand open and close is a spool, the motion of spool is a rectilinear motion.This class sand valve has the following disadvantages:
(1) since during the open and close of sand valve the motion of spool be rectilinear motion, be easy to sand grains etc. is brought among spool and the valve body, valve core movement is obstructed, cause the open and close of sand valve malfunctioning.
(2) because such sand valve does not have the second throttle device, the control ratio of amount of sand size is difficulty, causes disconnected sand or sand amount excessive often.
The utility model purpose is the problem that exists at above-mentioned sand valve arrangement pattern, design a kind of rational in infrastructure, reliability height, and can control the new structure of amount of sand.Sand controlling valve is made up of lock nut 1, adjustment screw 2, Connection Block 3, valve body 4, valve plate 5, push rod 6, connecting plate 7, Electrical heads 8, roller 9, sand-guiding tube 10, spring 11, impedance screw A12, valve gap 13, tube connector 14 and impedance screw B15 as shown in drawings.
Sand controlling valve structure and operation principle are as follows, and Connection Block 3 upper ends and sand bucket (not drawing among the figure) link, and lower end and valve body 4 link; Sand-guiding tube 10 is contained in the centre of valve body 4; Valve plate 5 is made by sheet metal, is installed on the valve body 4, and its profile is four faces, wherein on two faces an axis hole 5-1 is arranged respectively, and valve plate 5 can rotate around axis hole 5-1; Spring 11 left ends and valve body 4 link, and right-hand member and valve plate 5 link; Connecting plate 7 left ends and valve body 4 link, and right-hand member and Electrical heads 8 link; The valve rod (not drawing among the figure) of push rod 6 right-hand members and Electrical heads links; Roller 9 is installed in the left end of push rod 6, and link with valve plate 5, the left end of valve body 4 has an aperture and a screwed hole, and adjustment screw 2 is made up of external screw thread, the face of cylinder, the conical surface and two apertures of working hard in glove with mutually, and adjustment screw 2 and lock nut 1 are installed in the left end of valve body 4; Valve gap 13 links with the lower end of valve body 4; Tube connector 14 is contained in the lower end of valve gap 13, and the external diameter of impedance screw A12 and impedance screw B15 is a screw thread, and internal diameter is a via hole, is installed in the lower end of sand-guiding tube 10 and tube connector 14 respectively.When Electrical heads 8 when electric, the valve rod of Electrical heads promotes push rod 6 to left movement, and make valve plate 5 clockwise rotate certain angle around its axis hole 5-1 by roller 9, sand controlling valve is opened, and the sand grains in the sand bucket enters shower nozzle by Connection Block 3, sand-guiding tube 10, impedance screw A12, tube connector 14, impedance screw B15, plastic tube.When Electrical heads 8 dead electricity, valve plate 5 is under the effect of spring 11, and 5-1 rotates counterclockwise certain angle around its revolution axis hole, and sand flow is blocked by valve plate 5, and sand controlling valve is closed.The effect of impedance screw A12 and impedance screw B15 is the size that sand flow amount is wherein passed through in control.The effect of adjustment screw 2 and lock nut 1 is the size of vacuum in the regulation valve body, to guarantee supplying sand to connect, does not interrupt.
The utility model is compared with the technology of existing product, has following advantage:
(1) rectilinear motion that changes spool is the gyration of valve plate, is used for the switch of sand valve.Thoroughly changed the traditional structure of sand valve, novel.
(2) adopted the dual throttling arrangement of sand flow amount, the sand flow amount is controlled, the switch of sand valve and the control of sand flow amount have effectively been combined.
(3) increased the vacuum-ness regulator of valve body, guaranteed for the sand continuity.
(4) have characteristics such as rational in infrastructure, easy to use, dependable performance, life-span length.
Claims (1)
1, a kind of novel sand controlling valve is made up of lock nut (1), adjustment screw (2), Connection Block (3), valve body (4), valve plate (5), push rod (6), connecting plate (7), Electrical heads (8), roller (9), sand-guiding tube (10), spring (11), impedance screw A (12), valve gap (13), tube connector (14), impedance screw B (15) etc.It is characterized in that:
The open and close of a, described sand controlling valve are that the rotation by valve plate (5) realizes that valve plate (5) is made by sheet metal, and it has four faces, wherein on two faces an axis hole (5-1) is arranged, and rotate around it during valve plate (5) action;
B, described sand controlling valve are controlled the sand flow amount with impedance screw A (12) and impedance screw B (15).The impedance screw external diameter is a screw thread, and internal diameter is a via hole;
