detailed description

The utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model.

As shown in Figures 1 to 4, a valve with a water separator includes a valve body 1, the valve body 1 is provided with a water inlet 2, a water outlet, and a control port 3, and a water diverter is installed at the control port 3 The water distributor 4 includes an upper valve stem 5, and the upper valve stem 5 is fixedly connected with a handwheel 6 through the control port 3. The handwheel 6 is made of plastic material, and the lower end of the upper valve stem 5 Connected with the lower valve stem 7 that can move up and down by turning the handwheel 6, wherein the upper valve stem 5, the lower valve stem 7 and the handwheel 6 constitute the water separator 4, and the lower limit of the lower valve stem 7 moving down is to enable The position where the water distributor 4 closes the water outlet, that is, the lowermost end of the lower valve stem 7 can completely close the water outlet, the upper end of the upper valve stem 5 is provided with a ring of valve stem buckle grooves 8, and the corresponding handwheel 6 is provided with There is an elastic buckle 9 that matches the valve stem buckle groove 8. When installing, you only need to press the handwheel 6 to press the elastic buckle 9 into the valve stem buckle groove 8. At this time, the elastic buckle 9 cannot come out, realizing The locking function of upper valve stem 5 and handwheel 6 is realized.

The upper end 10 of the upper valve stem 5 is a hexagonal surface, and the joint between the hand wheel 6 and the upper valve stem 5 is provided with an inner hexagonal surface 11 matching the upper end 10, and the upper valve stem 5 passes through the hexagonal surface. The upper end 10 is inserted into the inner hexagonal surface 11 and fixedly connected, so that it can be ensured that the upper valve stem 5 rotates together with the handwheel 6 when it rotates, and there will be no idling phenomenon of the handwheel 6, because the handwheel 6 and the upper valve stem 5 are tightly connected. In contact, so there is less wear on each other, which improves the service life of the product.

Described lower valve stem 7 and upper valve stem 5 joints are provided with external thread 12, and upper valve stem 5 is provided with internal thread 13 matching with external thread 12, and lower valve stem 7 is connected with upper valve stem 5 by thread, and described The lower valve stem 7 is provided with a six-sided nut 13 that restricts the rotation of the lower valve stem 7. The six-sided nut 13 is installed in the control port 3. When the handwheel 6 is turned, the upper valve stem 5 rotates synchronously, so that the upper valve stem 5 pairs The lower valve stem 7 exerts a force of synchronous rotation. Since the six-sided nut 13 restricts the rotation of the lower valve stem 7, the lower valve stem 7 will not rotate synchronously with the upper valve stem 5. Valve stem 7 rotates relatively, because lower valve stem 7 and upper valve stem 5 are connected by thread, lower stem 7 will move up and down relative to upper valve stem 5, so as to reach the effect of closing or opening the water outlet.

The lower end of the lower valve stem 7 is provided with a soft sealing ring 14 and a hard sealing ring 15 for sealing the water outlet when the water outlet is closed. When the lower valve stem 7 closes the water outlet, double sealing can be realized to avoid water leakage.

The control port 3 is provided with a constriction 16, and the upper end of the upper valve stem 5 is also provided with a sealing ring baffle 17, and the outer diameter of the sealing ring baffle 17 is larger than the internal diameter of the constriction 16, avoiding the valve body 1. The internal water pressure is too high, and the water separator 4 is flushed out. In addition, the upper valve stem 5 can be provided with sealing ring baffles 17, and the sealing ring baffles 17 are used to arrange sealing rings.

To sum up the structure of the utility model, it can be known that the valve with a water separator of the utility model is provided with a fixing mechanism between the hand wheel and the valve stem, that is, the upper end of the upper valve stem is provided with a ring of valve stem buckle grooves, so that The elastic buckle matching the valve stem buckle groove is correspondingly arranged on the hand wheel, and the elastic buckle cannot come out after being pressed into the valve stem buckle groove corresponding to the upper valve stem, so as to realize the locking function and abandon the threaded connection , to ensure that the connection between the valve stem and the handwheel will not be loose, and the handwheel does not need to be replaced frequently, which reduces the cost and improves the work efficiency.
