Abstract

The utility model discloses an energy-saving type full-bore three-way ball valve. The energy-saving type full-bore three-way ball valve comprises a valve body, a ball body, valve seats and valve covers, wherein the ball body is arranged in the valve body, and three paths of the valve body are respectively provided with a valve cover; and the valve seats are arranged in grooves of the valve covers, and the ball body is tightly held by the valve seats in four directions to form sealing. The energy-saving type full-bore three-way ball valve has the advantages that the valve seats can be interchanged, which is convenient for assembly and disassembly, the production efficiency is improved, and the inventory is reduced; the volume of the valve body is reduced, so that material waste is reduced, and the cost is effectively reduced; the torque of the valve is reduced, and the service life of the valve is prolonged; and the valve seats can be recycled, and effective energy conversation of production can be realized.

Description

A kind of energy-saving all-pass footpath tee ball valve

Technical field

The utility model relates to a kind of all-pass footpath tee ball valve, and particularly a kind of energy-saving all-pass footpath tee ball valve is mainly used in all kinds of pipe-work fields that need distribution and interflow.

Background technique

The tee ball valve of producing in the market all has several identical shortcomings basically: the one, and all be that the threeway diameter ball valve all is a undergauge owing to what have in the market, have a strong impact on the trafficability performance of pipeline; The 2nd, its spheroid of tee ball valve is bigger on the market, and also rational data of neither one of the gap between spheroid and the valve body, causes the waste of ball material; The 3rd, moment of torsion is big, and the size of moment of torsion is to influence a valve principal element in working life, and moment of torsion is too little, can leak during valves test, and moment of torsion is too big, and the intensity and the spheroid of valve rod are accelerated the wearing and tearing of valve seat, also occurs premature leakage easily; The 4th, it is unreliable to seal, and the high low pressure repeated test all can be leaked, and has a strong impact on the use occasion of valve; The 5th, the valve seat thickness disunity of four direction, valve body can't exchange, and can't satisfy the requirement of user's needs change later on valve seat; The 6th, end face or screw thread between adjacent two valve seats or adjacent two valve gaps interfere with each other, and make that assembling can not be once successful; The 7th, valve seat can not be reused, when valve seat causes and can not reuse through two problems occurring after the dismounting once, and the one, because valve seat cylindrical and valve gap groove cooperate very tight when beginning to assemble; Adding upper sphere to after the valve seat extruding; Valve seat is difficult to take out in the valve gap groove, also breaks down even if taken out repeatedly, so can not reuse; The 2nd, spheroid is too big to the compression surplus of valve seat; Make valve seat produce plastic deformation, and lose the due function of valve seat, can not reuse.

Summary of the invention

To the shortcoming of existing tee ball valve, the utility model provides a kind of novel energy-saving all-pass footpath tee ball valve.

To achieve these goals, the measure taked of the utility model:

A kind of energy-saving all-pass footpath tee ball valve comprises valve body, spheroid, valve seat, valve gap, is provided with spheroid in the valve body, is respectively equipped with valve gap on three latus rectums of valve body; Valve seat is located in the groove of valve gap, and the valve seat of four direction is all held spheroid formation sealing tightly.

Furtherly, the end face of valve gap is a chamfering.

Furtherly, described chamfering is 45 °.

Furtherly, the external diameter of valve seat is slightly less than the internal diameter of valve gap groove.

Furtherly, valve seat rear end and valve gap groove bottom plane fit and form the end face axial sealing.

Furtherly, valve gap links to each other through screw thread with valve body.

Furtherly, valve gap groove bottom plane all equates to the distance of ball centre.

Furtherly, be spaced from each other certain distance between the two adjacent valve seat front-end faces.

Furtherly, the front end of valve seat has an inclined-plane to contact with the cambered surface of spheroid.The beneficial effect of the utility model: valve seat can exchange, and is convenient to loading and unloading; Can satisfy the user and change the requirement of accessory later at any time, and change former principle, improve manufacturing efficiency, reduce quantity in stock by singly joining; Valve body diminishes, and reduces waste of material, effectively reduces cost; The moment of torsion of valve reduces, the working life of having improved valve; Valve seat can be reused, and that can realize producing is effectively energy-conservation.

Fig. 2 is that the screw thread and the end face of two adjacent valve seats, two adjacent valve cover do not produce the partial sectional view of interference.

Embodiment

A kind of energy-saving all-pass footpath tee ball valve, as shown in Figure 1, a kind of energy-saving all-pass footpath tee ball valve comprises valve body 1, spheroid 2, valve seat 3, valve gap 4, is provided with spheroid 2 in the valve body 1; Four direction is provided with valve seat 3 around the spheroid 2, and valve seat 3 tops are provided with triangle part 22; 1 of spheroid 2 and valve body are provided with first distance 11, are provided with second distance 32 between adjacent valve seat 3 front-end faces.In the actual implementation process of patent, first aspect, described spheroid 2 is held tightly by the valve seat 3 of four direction; Form sealing reliably, and the intensity of the triangle part on satisfy spheroid 2 22 and valve seat 3 satisfy under the all-pass situation directly with the seal pressure of spheroid 2 with runner, sphere size is designed into minimum; In that the distance 11 between spheroid 2 and the valve body 1 is got the most moderate position, valve body is reduced, thereby changed the raw-material problems of waste such as original spheroid is big, valve body is big, the gap is big; Make present valve become delicate structure; Full flow, high tenacity, and reduced raw material and reduced cost.Owing to seal f ace width is got minimum value satisfying under the situation of seal pressure, thereby it is moderate that the external diameter of valve seat is also got, and makes the certain distance 32 of maintenances between the two adjacent valve seat front-end faces, changed the problem that produces interference between former two valve seats; Second aspect, said valve seat 3 is located in the groove of valve gap 4, and at the bottom of its rear end and groove plane fits and forms end face 21 axial seal structures; And valve seat 3 external diameters are slightly less than groove and directly form Spielpassung, have changed the former structure of leaning on radial seal, and valve seat 3 can be exchanged; Be convenient to loading and unloading; The front of described valve seat 3 has an inclined-plane to contact with spheroid 2 cambered surface faces, makes spheroid even to the compression of valve seat, and changes the compression surplus of valve seat 3 into relative value from former absolute value; Make valve seat become resiliently deformable, thereby make valve seat reusable by original plastic deformation.The third aspect; Distance (L) 31 between the valve gap annular groove bottom plane of described valve seat 3 centers to the four direction all equates; Valve seat thickness on the four direction is all equated; Valve seat can be exchanged at any time, changed and leaned on the custom of singly joining and reduced quantity in stock originally, and satisfied the requirement of needs replacing accessory after the user.Fourth aspect; Described valve gap end face outer radius is established one chamfering 13; Make the certain distance 41 of maintenance between the two adjacent valve cover ends, changed the original situation that the appearance of two adjacent valve cover end faces is interfered that always when assembling, often occurs, under the reliable situation of connecting thread intensity that satisfies between valve gap 4 and the valve body 1; Regulation valve body length, thus the situation that occurs interference between the two adjacent valve cover screw threads changed.Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in related domain.
