Abstract

A ball core steady-flow water mixing valve is characterized in that a connecting pipe (15) is fixed outside a valve casing (13); a valve chamber (14) is arranged inside the valve casing (13); the connecting pipe (15) is communicated with the valve chamber (14); a spherical valve core (10) is fixed in the valve chamber (14); the spherical valve core (10) is connected with a valve shaft (8) upwards; the valve shaft (8) penetrates the middle part of an upper cover (2) through a shaft hole (1) upwards; the upper cover (2) is fixed above the valve chamber (14) in the middle of the valve casing (13); and an open-ended arc-shaped slot (11) is formed on one part of the outer edge of the spherical valve core (10). The purposes that the isometric rotary adjustment of the spherical valve core (10) and the flow rate of a water outlet connecting pipe (15) being adjusted to be close to the linear stable variation by adopting the structure of the spherical valve core (10) and the arc-shaped slot (11) can be realized, and at the same time, the water mixing valve device capable of being sealed and separated between a first cavity and a second cavity has obvious flow stabilization effect, thereby resulting in strong suitability, simple and practical structure, and convenient installation, control, maintenance and operation.

Description

Ball core current stabilization mixes water valve

Technical field:

The utility model relates to the water-mixing valve device that is connected on the pipeline, and especially ball core current stabilization mixes water valve.

Background technique:

At present, tradition is mixed the tabular spool of the general employing of water valve, because the cause of structure, water intake flows to the water flow of valve pocket with the relation between the valve plate rotation angle presents severe nonlinear through the valve plate branch, makes the output hot and cold water mix water water temperature or heterogeneous liquid and is mixed and is difficult to control; In addition, the valve shaft of traditional four-way valve and the sealing between the valve casing can only lean on axle and " O " type circle at valve casing place to seal, and be reliable not to the utmost, easily leaks; And can not seal isolation between chamber and the secondary chamber, causing water temperature or proportioning Control Failure, relevant improvement technology is rarely open.

Summary of the invention:

The purpose of this utility model provide a kind of spool equivalent rotate adjust with the flow that adjusts the mouth of a river near linear steady change, mixed water valve device that can seal isolation between chamber and the secondary chamber, the i.e. mixed water valve of ball core current stabilization simultaneously.

Realize that the measure of the present utility model purpose comprises: the valve casing outer fixing is taken over, there is valve pocket valve casing inside, take over and be communicated with valve pocket, valve pocket internal fixation spherical valve core, spherical valve core upwards connects valve shaft, valve shaft upwards passes the loam cake middle part through axis hole, and loam cake is fixed on valve pocket top, valve casing middle part, and the local outer rim of spherical valve core has open arc gap groove.

The utility model advantage: spherical valve core and arc gap groove structure, effectively realization spherical valve core equivalent is rotated and is adjusted and adjust the approaching linear steady change of the flow of taking at the mouth of a river, mixed water valve device that can seal isolation between chamber and the secondary chamber simultaneously, steady flow result is obvious, adaptability is strong, structure is concisely practical, is convenient to installation, control, maintenance and operation.

Description of drawings:

Fig. 1 is the utility model embodiment 1 a structural representation

Reference character comprises: axis hole 1, loam cake 2, press hole 3, bayonet socket 4, press skirt 5, on encircle 6, wheel shaft axle envelope 7, valve shaft 8, on seal 9, spherical valve core 10, short slot 11, lower seal 12, valve casing 13, valve pocket 14, take over 15, hold hole 16, water inlet internal orifice 17.

Embodiment:

Embodiment 1: valve casing 13 outer fixing take over 15, there is valve pocket 14 valve casing 13 inside, taking over 15 is communicated with valve pocket 14, valve pocket 14 internal fixation spherical valve cores 10, spherical valve core 10 upwards connects valve shaft 8, valve shaft 8 upwards passes loam cake 2 middle parts through axis hole 1, and loam cake 2 is fixed on valve casing 13 middle part valve pockets 14 tops, and spherical valve core 10 local outer rims have open arc gap groove 11.

Loam cake 2 edges are installed with presses hole 3, and valve casing 13 upper edge correspondences are installed with holds hole 16., by pressing hole 3 and holding hole 16 loam cake 2 is pressed solidly in valve casing 13 upper edges with bolt.

The fixedly connected tubular of loam cake 2 downsides is pressed skirt 5, presses skirt 5 lower limb outer walls to open bayonet socket 4, and bayonet socket 4 is corresponding with the opening of adapter 15 in valve pocket 14.

Spherical valve core 10 downside gasket ring shape lower seals 12, lower seal 12 is seated at valve pocket 14 inner bottom parts, seal 9 on the spherical valve core 10 upside casing pressure annulars, on encircle 6 and be socketed in and press skirt 5 upper edges and be close to loam cake 2 lower surfaces, wheel shaft axle envelope 7 is socketed in valve shaft 8 external compressions above spherical valve core 10 and axis hole 1 downside.

Four of valve casing 13 outer fixing take over 15.

Spherical valve core 10 local outer rim symmetries have two open arc gap grooves 11, on valve pocket 14 inwalls, be communicated with the position as the adapter 15 of water intake water inlet internal orifice 17 is set, water inlet internal orifice 17 ovalizes cooperate with arc gap groove 11, connect position formation sub-circular and pass through the hole.

Last ring 6, wheel shaft axle envelope 7, on seal 9, lower seal 12 is teflon seal ring.

When the utility model embodiment uses, utilize spherical crown, spherical valve pocket 14 and the teflon seal ring of spherical valve core 10 to match, fundamentally solved the sealing between chamber and secondary chamber and the sealing of rotatingshaft valve shaft 8.In addition, relative two the adapter 15 water intake flows of spherical valve core 10 effective adjusting in 90 ° of scopes have been guaranteed by the opening of adapter 15 in valve pocket 14 with the oval water intake that arc gap groove 11 forms, changed the non-linear relation between spherical valve core 10 corners and the inflow simultaneously, made basic retention wire sexual intercourse between the corner angle of spherical valve core 10 and the inflow.

Among the utility model embodiment, spherical valve core 10 and arc gap groove 11 structures, effective realization spherical valve core 10 equivalent are rotated and are adjusted and the approaching linear steady change of the flow that adjusts mouth of a river adapter 15, mixed water valve device that can seal isolation between chamber and the secondary chamber simultaneously, steady flow result is obvious, adaptability is strong, and structure is concisely practical, is convenient to installation, control, maintenance and operation.
