Abstract

The utility model relates to a stainless steel ball valve which mainly comprises a valve seat, a valve core, a pin, a fixing nut, a hexagonal bolt and a switch handle, wherein the valve core is arranged in the middle of the valve seat lumen and controlled by the hexagonal bolt and a project; the lower end of the pin is inserted in a groove of the valve core; the pin is fixed on the valve seat by the fixing nut; a plastic washer is arranged between the pin and the valve seat; the upper end of the pin is sheathed in the switch handle and is fixed by the fixing nut. Because the plastic washer is arranged between the pin and the valve seat and fixed by the fixing nut, the utility model effectively avoids the phenomena of air leakage and water penetration on the contact point.

Description

Stainless Steel Ball Valve (1)

The utility model relates to waterway fitting.

The various ball valve sealing performances of using are bad at present, after use a period of time, and not only gas leakage, but also cause percolating water phenomenon, waste water resource on the other hand, after oozing for a long time, leaking, very easily forms the scale vestige on the one hand, brings inconvenience to family.

The purpose of this utility model is the Stainless Steel Ball Valve of a kind of good seal performance of design and non-leakage water.

The technological scheme of the utility model design: formed by valve seat, spool, pin, hold-doun nut, hex head bolt and switch handle, spool is in the central authorities of valve seat tube chamber, and control about it by hex head bolt and mound movable, then, pin inserts in the spool groove, fix pin with hold-doun nut, simultaneously, install switch handle in the pin upper end, and get final product with set screw nut is fixing, when switch handle horizontally rotates, pin rotating band movable valve plug horizontally rotates, thereby it is unobstructed to open or close tube chamber.

Described valve seat, bobbin chamber, a garden, the two ends inwall made by stainless steel are provided with screw thread, and mound at one end also is set, the outside, two ends corresponding surface is whittled into flat horizontal surface, and a draw-in groove is set above two ends, and the centre is provided with hole, a garden, the Qi Yuan hole communicates with valve base cavity, and inwall place, hole, garden is provided with screw thread.

Described spool is a steel ball body, in the medial axis tube chamber is set, groove of spheroid arranged outside.

Described pin, with the Cylinder that stainless steel is made, the upper end is provided with screw thread, makes flat horizontal surface in corresponding both sides, and the lower end is whittled into flat horizontal surface, and intermediate section and jointing place, lower end are provided with along the limit, stop plastic washer toward gliding.

Described hold-doun nut, centre are got the Cheng Yuan hole, and size and pin coincide, and arranged outside screw thread, shade are hexagonal.

Described switch handle is made flat strip by stainless steel, and the centre is provided with a microscler square hole, and size and pin upper end coincide, and an end is provided with trip, an end is a handle, has trip one end to turn right slightly and departs from.

The utility model adopts above-mentioned measure, and compared with prior art, this model utility has excellent sealing performance, and can effectively prevent percolating water, characteristics such as growth in working life.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 4. the planimetric map of switch handle in the Stainless Steel Ball Valve of the present utility model.

The figure number explanation:

1 valve seat, 11 mounds, 12 draw-in grooves, 2 spools

21 tube chambers, 22 grooves, 3 pins, 31 set screw nuts

32 hold-doun nuts, 33 plastic washers 34 are 4 switch handles along the limit

41 handles, 42 trips, 43 microscler square hole 5 hex head bolts

6 packing rings, 7,8 plastic washers

With reference to Fig. 1～Fig. 4, can find out, Stainless Steel Ball Valve of the present utility model is by valve seat 1, spool 2, pin 3, hold-doun nut 32, hex head bolt 5 and switch handle 4 are formed, valve seat 1 is a stainless steel garden tubular tube chamber, on central authorities' body wall the hole, garden is set, spool 2 is installed in the middle of the tube chamber of valve seat 1, a plastic washer 7 is each side arranged, 8, at plastic washer 7 and 5 of hex head bolts stainless steel packing ring 6 is set also, with hex head bolt 5 screw extrusion and mound 11 spool 2 is controlled then, make spool 2 can not about movable, and the hole, garden that the groove 22 on the spool 2 is aimed in the valve seat 1, then in the groove 22 on the pin 3 insertion spools 2, and pin 3 is controlled on the valve seat 1 with hold-doun nut 32, sealing of hold-doun nut 32 and pin along a plastic washer 33 is set between the limit, be inserted in the upper end that microscler square hole on the switch handle 4 43 is aimed at pin 3 at last, and get final product with set screw nut 31 is fixing, like this, as long as people hold handle 41 and move horizontally, and with trip 42 and draw-in groove 12 Joystick angle of swing, thereby open or close the unobstructed of tube chamber 21 in the spool 2.
