An object of the utility model is to provide a three -way ball valve lies in the more effective sealing performance who guarantees the valve.
Description
Technical field
The utility model relates to a kind of valve, and more particularly it relates to a kind of tee ball valve.
Background technique
Tee ball valve refers to the ball valve with three circulation passages.In prior art application number be 032196172 Chinese patent document disclose a kind of tee ball valve, comprise valve body, valve seat, valve rod, spheroid and driving handle, valve rod one end is fixedly connected with spheroid, the other end is connected with driving handle, valve body is three-port structure, it is characterized in that valve seat is floating stack valve seat.
The valve body of tee ball valve of the prior art includes three passages that stretch out, and all seals and contacted valve seat between passway with spheroid.Existing valve seat mainly contains two kinds of forms, the fixed hard seal valve seat of a kind of valve seat, this valve base seal property is comparatively stable, but easily and produce rigidity between spheroid and wear and tear, another kind of as described in above-mentioned patent, usually the parts being provided with resilient pad and so between valve body and valve seat give valve seat stronger sealing, but because elastic member all can exist elastic fatigue failure phenomenon usually, after elastic member elasticity weakens, it weakens the supporting effect of valve seat, valve seat just easily produces skew thus causes valve seat cannot closely cooperate with ball valve, cause leaking.And be loaded in the valve pocket of valve body in valve seat of the prior art, changing elastic member just needs valve entirety taken apart and take out spheroid, very inconvenient.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of tee ball valve, is the sealability of more effective guarantee valve.
For achieving the above object, the utility model provides following technological scheme: a kind of tee ball valve, comprise valve body, spheroid, valve seat, valve rod and handle, valve body comprises valve gap and the valve pocket for installing spheroid, described valve body is connected with three runner pipes, runner pipe all communicates with valve pocket, the opening that described runner pipe is connected with valve pocket is equipped with valve seat, valve seat and spheroid fit tightly, described runner pipe is all threadedly connected to valve body, one end of the relative valve pocket of described runner pipe is provided with elastic cushion, and described runner pipe contacts at valve seat by elastic cushion.
The utility model effect is compared to existing technology, weaken and the problem causing valve seat to offset to overcome existing elastic member elastic force, the mode be connected with valve body screw thread is arranged to by runner pipe by the utility model, and its relative valve pocket one end is provided with elastic cushion, and contact at valve seat by elastic cushion.Under normal circumstances, elastic cushion can give valve seat certain elastic anchorage force, make the contact of valve seat and spheroid tightr, better tightness, avoid the rigidity between valve seat and spheroid to wear and tear simultaneously, when elastic cushion elasticity weakens, by screwing runner pipe to valve pocket direction, runner pipe is made to oppress elastic cushion, thus make up the flexibility missing of elastic cushion part, and then compressing valve seat, make valve seat still can realize closely cooperating with spheroid, after elastic cushion lost efficacy, can directly runner pipe be taken out and can change elastic cushion.By adopting technique scheme, effectively ensure that sealability and the wear resistance of this tee ball valve, facilitating the replacing of elastic cushion simultaneously, using more convenient.
The utility model is set to further: the threaded connection place of described runner pipe and valve body is equipped with seal ring.
By adopting technique scheme, the sealability of runner pipe and valve body screw thread joint can be improved.
The utility model is set to further: described elastic cushion is rubber pad, and described rubber pad is adhered to the opening edge of the relative valve pocket one end of runner pipe.
By adopting technique scheme, rubber pad not only have very strong elasticity also have resistance to wear, the characteristic such as corrosion, pretend as preferred consideration.
The utility model is set to further: the other end of the relative valve pocket of described runner pipe is equipped with ready-packaged joint.
By adopting technique scheme, being connected with other pipeline fast by clip by arranging ready-packaged joint in the outer end of runner pipe, installing quick and convenient.
Accompanying drawing explanation
Fig. 1 is the half sectional view of tee ball valve described in the present embodiment.
Description of reference numerals: 1, valve body; 2, spheroid; 3, valve seat; 4, valve rod; 5, handle; 6, elastic cushion; 7, seal ring; 11, valve gap; 12, runner pipe; 13, threaded connection place; 14, ready-packaged joint.
Embodiment
With reference to Fig. 1, the utility model embodiment is described further.
Tee ball valve described in the present embodiment, as shown in Figure 1, comprise valve body 1, spheroid 2, valve seat 3, valve rod 4 and handle 5, valve body 1 comprises valve gap 11 and the valve pocket for installing spheroid 2, described valve body 1 is connected with three runner pipes 12, runner pipe 12 all communicates with valve pocket, the opening that described runner pipe 12 is connected with valve pocket is equipped with valve seat 3, valve seat 3 and spheroid 2 fit tightly, described runner pipe 12 is all threadedly connected to valve body 1, one end of the relative valve pocket of described runner pipe 12 is provided with elastic cushion 6, and described runner pipe 12 contacts at valve seat 3 by elastic cushion 6.Described elastic cushion 6 is preferably rubber pad, described rubber pad is adhered to the opening edge of the relative valve pocket one end of runner pipe 12, rubber pad not only have very strong elasticity also have resistance to wear, the characteristic such as corrosion, pretend as preferred consideration, but other softness has flexible material also can be used as consideration, as leather etc.
Effect of the present utility model is, weaken to overcome existing elastic member elastic force and cause the problem that valve seat 3 offsets, the mode be threaded with valve body 1 is arranged to by runner pipe 12 by the utility model, and its relative valve pocket one end is provided with elastic cushion 6, and contacts at valve seat 3 by elastic cushion 6.Under normal circumstances, elastic cushion 6 can give valve seat 3 certain elastic anchorage force, make valve seat 3 tightr with the contact of spheroid 2, better tightness, avoid the rigidity between valve seat 3 and spheroid 2 to wear and tear simultaneously, when elastic cushion 6 elasticity weakens, by screwing runner pipe 12 to valve pocket direction, runner pipe 12 is made to oppress elastic cushion 6, thus make up the flexibility missing of elastic cushion 6 part, and then compressing valve seat 3, make valve seat 3 still can realize closely cooperating with spheroid 2, after elastic cushion 6 lost efficacy, can directly runner pipe 12 be taken out and can change elastic cushion 6.By adopting technique scheme, effectively ensure that sealability and the wear resistance of this tee ball valve, facilitating the replacing of elastic cushion 6 simultaneously, using more convenient.
Further, described runner pipe 12 is equipped with seal ring 7 with the threaded connection place of valve body 1.As shown in Figure 1, seal ring 7 is arranged at the opposite exterior lateral sides of threaded connection place, at the flange of arranged outside one radial protrusion of runner pipe 12 opposite thread section, seal ring 7 is sheathed on the side of flange opposite thread section, when runner pipe 12 is threaded with valve body 1, seal ring 7 is pressed between valve gap 11 and runner pipe 12, thus the effective sealing of thread section.
Further optimization, the other end of the relative valve pocket of described runner pipe 12 is equipped with ready-packaged joint 14.Be connected with other pipeline fast by clip by arranging ready-packaged joint 14 in the outer end of runner pipe 12, install quick and convenient.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
