Description

A kind of multiple channel ball core valve

The present invention relates to the multichannel ball core valve of a kind of may command.

Existing multiple channel ball core valve, in life, be extensive use of, Chinese patent ZL 93238897.3 (CN2161789Y) disclosed a kind of " spring precompressed turn valve " for example, comprise valve body, valve ball, handle, top cover, stage clip, top board, turning handle, its deficiency is that the joint on the valve body is too much; Body cavity is that polymorphic structure is so that processing difficulties, manufacture cost height are caused in the valve ball location therefore; The multi-orifices apron of the O-ring seal of valve ball and water outlet is difficult for adjusting, and leaks easily.

The object of the present invention is to provide that a kind of valve body upper connection is less, the body cavity shape is simpler.Easy processing, the multiple channel ball core valve of good airproof performance.

The object of the present invention is achieved like this; A kind of multiple channel ball core valve comprises valve body, ball core, core bar, handle, O-ring seal, pressing plate, loaded spring, ball core positioning rib.Core bar joint, water intake and water outlet are arranged on the valve body, and body cavity is cylindrical, at intracavity bottom ball core positioning rib is set, and the ball core is located.The ball core is contained in the body cavity bottom surface, is connected core bar upper end dress handle with core bar with the groove on it.The ball core can be two and connects the ball core, and the ball in-core has central blind hole, on the last ball of ball core and the surface of following ball a hole that communicates with center hole is arranged respectively, differs several angle between last ball and the following ball surface holes, can connect with upper water-out mouth and lower outlet respectively.On upper water-out mouth and lower outlet, with the last ball and the following ball touching position of ball core, respectively adorn an O-ring seal, make its good seal, water-tight.Pressing plate and loaded spring are pressed on the ball core by packing in the water intake, give the ball core certain precompression.Precompression chamber and water intake are integrated, and have therefore reduced the piece-ups on the valve body.The roating sphere core can be connected upper and lower water outlet respectively and close, and be closed simultaneously.

Also can open 2 on two surfaces that connect a ball of ball cores and differ 180 ° and the hole that communicates with center hole; The hole of opening 90 ° in 2 mutual angles of cut and communicating with center hole on another ball surface, and a hole on the sphere of one of them hole and an aforementioned ball is positioned at same angle.Adopt this two to connect the ball core, can connect, close upper and lower water outlet separately, also can connect and close two water outlets simultaneously.

Also can adopt three to connect the ball core, middle water outlet is set between upper water-out mouth and lower outlet, on the middle ball surface between last ball and the following ball, a hole that communicates with center hole is arranged, and this hole and last ball and the lip-deep hole of following ball differ 90 ° of angles, can connect and close the upper, middle and lower water outlet respectively.

The present invention compared with prior art, it is less to have a valve body upper connection, cavity shape is simple, the advantage of easy processing, low cost of manufacture, good airproof performance, antileaking.

Fig. 1 is a structural drawing of the present invention.Fig. 1 is described as follows: 1 is valve body, and 2 is the ball core, and 3 is core bar, 4 is handle, and 5 is O-ring seal, and 6 is pressing plate, 7 is loaded spring, and 8 is ball core positioning rib, and 9 is the core bar joint, 10 is the core bar collar nut, 11 is water intake, and 12 is the water intake nut, and 13 is the upper water-out mouth, 14 is lower outlet, and 15 are the circle of obturaging.

Fig. 2 analyses and observe circle for the two company's ball cores that can connect and close simultaneously two water outlets simultaneously.

Fig. 3 connects ball core sectional view for connecting, close three of three water outlets in upper, middle and lower separately.

Below in conjunction with Fig. 1 and embodiment, the present invention is further illustrated: core bar joint 9, water intake 11, upper water-out mouth 13 and lower outlet 14 are arranged on the valve body 1.Valve body 1 inner chamber is cylindrical, at intracavity bottom 6 ball core positioning ribs 8 is set, and with ball core 2 location, inner chamber is compared easier processing with the special-shaped inner chamber of prior art.Ball core 2 is contained in the inner chamber bottom surface, is connected with core bar 3 with the groove on it.Core bar 3 is contained in the core bar joint 9, overcoat core bar collar nut 10, the upper end dress handle 4 of core bar 3.Ball core 2 is two company's ball cores, in the ball core 2 central blind hole is arranged, on the last ball of ball core 2 and the surface of following ball a hole that communicates with center hole is arranged respectively, angle differs 180 ° between last ball surface holes and the following ball surface holes, can be communicated with upper water-out mouth 13 and lower outlet 14 respectively.On upper water-out mouth 13 and lower outlet 14, with ball on the ball core 2 and following ball touching position, respectively adorn an O-ring seal 5, to guarantee good sealing property, water-tight.Pressing plate 6 and loaded spring 7 are packed into by water intake 11, are pressed on the ball core 2, and overcoat water intake nut 12 adds certain precompression for ball core 2, and compared with prior art, precompression chamber and water intake are combined into a place.When ball core 2 is on the home position shown in Figure 1, connect lower outlet 14, close upper water-out mouth 13; Ball core 2 is from the home position, and when rotating 90 °, two water outlets are all closed, and rotate 90 ° again, then close lower outlet 14, connects upper water-out mouth 13.

Adopt two company's ball cores shown in Figure 2, when ball core 2 is in home position shown in Figure 2, connect upper water-out mouth 13, close lower outlet 14; When looking from top to bottom when clockwise rotating 90 ° in ball core, two water outlets are all closed; Rotate 90 ° again when spending, two water outlets are all connected; When rotating 90 ° again, upper water-out mouth 13 is closed, and lower outlet 14 is communicated with.

Adopt shown in Figure 3 three to connect the ball cores, when on the home position shown in the ball core is on the figure, connect the upper water-out mouth, in closing, lower outlet; When looking 90 ° in clockwise direction roating sphere core from top to bottom, three water outlets are all closed; Rotate 90 ° again, lower outlet is communicated with, and upper water-out mouth and middle water outlet are closed; Rotate 90 ° again, then middle water outlet is communicated with, and upper water-out mouth and lower outlet are closed.
