The utility model discloses a control valve which comprises a valve body, a middle partition plate and an upper cover. Water inlets are formed in side walls of the valve body, a cavity is arranged inside the valve body, a central column and a plurality of reinforcing ribs are arranged in the cavity inside the valve body, one end of each reinforcing rib is connected with the central column, the other end of each reinforcing rib is connected with the corresponding side wall of the valve body, and each two adjacent reinforcing ribs, the central column and the inner wall of the valve body form a chamber. Both the middle partition plate and the upper cover are arranged in the cavity of the valve body, the middle partition plate is positioned on the upper sides of the chambers, and the upper cover is positioned on the upper side of the middle partition plate. The control valve has the advantages that a structure comprising the middle partition plate and the upper cover are arranged in the valve body, so that the pressure resistance and the sealing performance of the control valve are further improved; the reinforcing ribs are arranged in the valve body, accordingly, the problem of furcating flow of water is solved, and the pressure resistance and the fatigue resistance of the integral valve body are improved.
Description
Technical field
The utility model relates to control valve, is specifically related to a kind of control valve in water treatment system.
Background technique
Plastics water treatment multifunctional control valve processed is the core component in the former water treatment system now, the stability of this assembly directly has influence on whole system operation efficient, because the restriction of the strength of materials of plastics itself, make that having valve body now can occur quality problems because compressive strength and fatigue resistance are not high always.Secondly, because being a valve, multifunctional control valve realizes the function that 3～4 ordinary ball valve combinations produce simultaneously, so must go out at least 4 chambers in internal structure, but it is enough big to make that just because of the formation of these chambers valve body must be done, and excessive diameter has caused the not resistance to compression of valve body and fatigue resistance not indirectly.
Existing plastics water treatment multifunctional control valve processed internal chamber structure adopts double-deck socket pattern to connect, and namely valve body separates with the structure of formation chamber in the valve body, forms the structure of a big casing keg, and the gap of drum and keg is as water intake.1., adopt the bottom to place special-shaped O type circle this mode has following defective:, two parts extruding mutually seal, because the plastics core mostly is hollow, pressure distribution is inhomogeneous, causes the crossfire of water between each chamber of bottom easily; 2., the sleeve seal of two parts adopts glue bonding, complex process and defect rate height during machine shaping, in a single day glue can not evenly cover, then also cause crossfire between the outboard chambers easily, and glue forms tiny water channel easily after having done, and also causes the crossfire of water; 3., the compressive strength of valve body is not high, reach corresponding pressure test, requiring must be by the thickened sides wall thickness, waste material increases cost of production virtually.
The model utility content
The purpose of this utility model is for the control valve that provides a kind of anti-pressure ability and anti-fatigue ability to strengthen, good seal performance, and the adhesive strength between the parts increases.
In order to reach the purpose of this utility model, technological scheme is as follows:
A kind of control valve, comprise valve body, also comprise central diaphragm and loam cake, described central diaphragm and described on cover and be provided with the perforation that several run through upper and lower surface, the sidewall of described valve body is provided with water intake, described valve inner has cavity, be provided with newel and some stiffening ribs in the cavity of described valve inner, one end of described stiffening rib is connected with described newel, the other end of described stiffening rib is connected with the sidewall of described valve body, and the inwall of every adjacent two stiffening ribs and described newel and described valve body forms a chamber.
Described central diaphragm and described loam cake all are arranged in the cavity of described valve body, and described central diaphragm is positioned at the upside of described chamber, and described loam cake is positioned at the upside of described central diaphragm.
Further, the quantity of described stiffening rib is 4～8, and further, the quantity of described stiffening rib is 5.
Further, described valve inner cavity forms chamber A, chamber B, cavity C, chamber D and chamber E.
Further, described chamber A is communicated with described water intake.
Further, the central angle of described chamber A is 60 °～110 °, and preferably, the central angle of described chamber A is 70 °.
Further, the external diameter of described central diaphragm is identical with the internal diameter of described valve body.
Further, the external diameter of described loam cake is identical with the internal diameter of described valve body
In the utility model, the central angle of chamber A, the inwall that refers to valve body is arranged in the number of degrees of the segmental arc of chamber A.
The beneficial effect that the utlity model has:
Adopt the structure that central diaphragm and loam cake are set in the valve body, further strengthened anti-pressure ability and the seal of control valve.
By stiffening rib is set in valve body, chamber utilizes stiffening rib to form, and makes valve body become integrated structure, does not need to apply mechanically formation with two structures again.This has not only been avoided bonding with glue, has simplified production technology, has improved yield rate, has also solved the crossfire problem of water simultaneously; In addition, constitute the stiffening rib of each chamber, the sidewall of valve body has also been played the effect of supporting, strengthened anti-pressure ability and the anti-fatigue ability of whole valve body.
