Description
Technical field
The utility model relates to the technical field of valve, more particularly relates to the technical field of stop valve.
Background technique
Valve is the device being used for controlling the direction of fluid, pressure and flow in fluid system, it mainly includes gate valve, stop valve, safety check, membrane valve, ball valve, stopcock, dish valve, plunger valve and ball valve etc., the sealability of valve refers to that each sealed department steric hindrance of valve stops the ability of dielectric leakage, and it is the most important technical performance index of valve.Three-way cut-off valve is the type in valve, belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.Three-way cut-off valve and two-way stop valve the most obvious difference are in appearance exactly many runner mouths.Three-way cut-off valve can flow to by control media, and it is except import and outlet, and commutate mouth usually in addition, and two-way stop valve does not possess to change MEDIA FLOW to function.But, current existing three-way cut-off valve is when control media flows to, medium can only flow out from an outlet usually, another outlet is in closed state, can not accomplish that two outlets have medium to flow out simultaneously, use in part industry and place and be often subject to various restriction, thus bring inconvenience to production.
Model utility content
The purpose of this utility model provides a kind of structural design very reasonable to solve above-mentioned deficiency exactly, MEDIA FLOW is to controlled flexibly, two outlets can be opened simultaneously, also only can open an outlet, the three-way cut-off valve that very convenient various industry and place use.
The technical solution that the utility model adopts to solve the problems of the technologies described above is as follows:
Three-way cut-off valve, it mainly includes valve body, valve gap, valve rod and flap, described valve bonnet seal lid is put on valve body, valve handle activity is arranged on valve gap, the lower end of this valve rod is positioned at valve body, it also includes valve clack cover, the middle part of described valve body is provided with import, upper outlet and lower outlet is respectively arranged with in the upper side and lower side of this valve body, the valve seat be connected with lower outlet with upper outlet in this valve body is equipped with cemented carbide, described flap entirety is in I-shaped, this flap offers screw, the center of valve clack cover offers center hole, arranged outside has screw thread, the lower end of described valve rod is plugged in the screw of flap, valve clack cover is nested with on valve rod by its center hole, be located in the screw of flap by the screw thread outside it, the upper side and lower side of described flap is corresponding with the upper lower valve base inside valve body respectively.
The upper side and lower side of described flap is equipped with cemented carbide.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: structural design is very reasonable, MEDIA FLOW is to controlled flexibly, two outlets can be opened simultaneously, also one of them outlet can only be opened, very convenient various industry and place use, because stop valve is two-way valve, the import on its valve body and outlet can exchange use flexibly, the flow direction of such medium and blocking more flexible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, three-way cut-off valve, it mainly includes valve body 1, valve gap 2, valve rod 3, flap 4 and valve clack cover 5, described valve gap 2 sealing cover is put on valve body 1, valve rod 3 is movably arranged on valve gap 2, the lower end of this valve rod 3 is positioned at valve body 1, the middle part of described valve body 1 is provided with import 6, upper outlet 7 and lower outlet 8 is respectively arranged with in the upper side and lower side of this valve body 1, the valve seat 9 be connected with lower outlet 8 with upper outlet 7 in this valve body 1 is equipped with cemented carbide, described flap 4 entirety is in I-shaped, this flap 4 offers screw 10, the center of valve clack cover 5 offers center hole, arranged outside has screw thread, the lower end of described valve rod 3 is plugged in the screw 10 of flap 4, valve clack cover 5 is nested with on valve rod 3 by its center hole, be located in the screw 10 of flap 4 by the screw thread outside it, valve rod 3 lock is put on flap 4 by valve clack cover 5, the upper side and lower side of described flap 4 is corresponding with the upper lower valve base 9 inside valve body 1 respectively, in order to effectively improve the working life of flap 4 and the sealability with valve seat 9, also cemented carbide is equipped with in the upper side and lower side of flap 4.
