Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Below with reference to Fig. 1 and Fig. 2, the utility model is described.
A kind of bellows stop valve, comprise valve body 1 and be located at the valve gap 2 on valve body 1, valve rod 3 is equipped with in the middle part of described valve gap 2, described valve rod 3 lower end is provided with flap 4, described valve body 1 left end offers feed pathway 5, described valve body 1 right-hand member offers liquid outlet channel 6, between described feed pathway 5 and liquid outlet channel 6, valve body is provided with channel partition 7, described channel partition 7 upper end is provided with the connecting port 8 being communicated with feed pathway 5 and liquid outlet channel 6, described connecting port 8 lower end is installed with filter screen 9, described feed pathway 6 internal face lower end is provided with arc-shaped concave 10, and valve body 1 be positioned at arc-shaped concave 10 medium position offer collection dirty groove 11, and collect dirty groove 11 lower end and be provided with drain outlet 12, described drain outlet 12 external port is provided with sealing nut 13, sealing nut 13 and drain outlet 12 screw-thread fit, described flap 4 is made up of elastic caoutchouc, and the upper plane of described connecting port 8 and the lower plane of flap 4 form sealing surface, and the upper plane of described connecting port 8 is provided with annular projection 130, described connecting port 8 is taper wide at the top and narrow at the bottom, and described flap 4 lower plane is provided with the frustum 14 stretched in connecting port 8, and the sidewall of described frustum 14 and the inwall of connecting port 8 are formed and be sealed and matched.
The cross section of protruding 130 is semicircle, and this setting can reduce the frictional force between protruding 130 and flap 4, reduces the wearing and tearing of flap 4.
Protruding 130 are arranged near connecting port 8 edge, this setting can increase the sealing of flap 4 further, when the projection 130 that close connecting port 8 edge is arranged forces flap 4 that elastic strain occurs, deformation can occur with side, frustum 14 place indirectly make the sealing of flap 4 and frustum 14 and connecting port 8 tighter outside flap 4.
