Abstract
The utility model discloses a valve clack of a stop valve. The technical scheme is characterized in that the valve clack of the stop valve comprises a body and a seal head which are integrated, wherein the body is cylindrical; the seal head is conical; the body is provided with a cylindrical groove for accommodating a valve rod; one end of the seal head opposite to the end connected with the body is provided with a hollowed part; and the hollowed part forms a cushion chamber. According to the valve clack of the stop valve, the structural design of the seal head of the valve clack is improved, so that an elastic seal is formed between the seal head and a valve seat, and the leakproofness of the stop valve is improved.
Description
Technical field
The utility model relates to valve field, and more particularly, it relates to a kind of stop valve clack.
Background technique
The open-shut device of stop valve is the flap of stopper, and sealing surface is plane conventionally, and flap is done straight line motion along the center line of valve seat.The sealing of flap and valve seat is particularly important, and Chinese utility model patent number is 201220663857 to disclose a kind of stop valve and flap, and described flap comprises interconnective main body 1 and sealing head 2, and described sealing head 1 is cone shape.Between the design flap of this stop valve clack and valve seat, sealing contact as firmly sealing, and sealability is poor.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of stop valve clack, and the design that this stop valve clack has improved sealing configuration has improved the sealing of stop valve.
For achieving the above object, the utility model provides following technological scheme: a kind of stop valve clack, comprise and be main body and the sealing head being wholely set, described main body is cylindrical shape, described sealing head is cone shape, described main body is provided with for the cylinder shape groove of valve rod is installed, and one end that described sealing head connects main body relatively arranges hollow part, and described hollow part forms buffer cavity.
By adopting technique scheme, in sealing head end, hollow part is set, hollow part forms a buffer cavity, makes to make while coordinating between sealing head and valve seat sealing head to have the space of a distortion, causes and between sealing head and valve seat, forms the sealability that elastic packing has improved stop valve.
The utility model is further set to: in described buffer cavity, be provided with buffer part, described buffer part is cone shape, and the large end face of described buffer part is connected with buffer cavity bottom.
By adopting technique scheme, the buffer part of a cone shape is set in buffer cavity, make the stressing conditions of stop valve clack have obvious change, the pressure of liquid is resolved into positive force has increased the sealing force between stop valve clack and valve seat, thereby has improved sealability.
The utility model is further set to: described buffer part and sealing head are and are wholely set.
By adopting technique scheme, buffer part and sealing head are wholely set, and can improve the intensity of stop valve clack.
The utility model is further set to: described sealing head electroplating anticorrosion zinc layer.
By adopting technique scheme, in sealing head electroplating anticorrosion zinc layer, the working life that can improve stop valve clack.
Accompanying drawing explanation
Fig. 1 is the utility model stop valve clack embodiment 1 structural representation;
Fig. 2 is the utility model stop valve clack embodiment 2 structural representation;
Fig. 3 is the structural representation of stop valve clack of the prior art.
Reference character: 1, main body; 11, cylinder shape groove; 2, sealing head; 21, buffer cavity; 211, buffer part.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model stop valve clack embodiment is described further.
A kind of stop valve clack, comprise and be main body 1 and the sealing head 2 being wholely set, described main body 1 is cylindrical shape, described sealing head 2 is cone shape, described main body 1 is provided with for the cylinder shape groove 11 of valve rod is installed, one end that described sealing head 2 connects main body 1 relatively arranges hollow part, and described hollow part forms buffer cavity 21.
By adopting technique scheme, in sealing head 2 ends, hollow part is set, hollow part forms a buffer cavity 21, makes to make while coordinating between sealing head 2 and valve seat sealing head 2 to have the space of a distortion, causes and between sealing head 2 and valve seat, forms the sealability that elastic packing has improved stop valve.
In described buffer cavity 21, be provided with buffer part 211, described buffer part 211 is cone shape, and the large end face of described buffer part 211 is connected with buffer cavity 21 bottoms.
By adopting technique scheme, the buffer part 211 of a cone shape is set in buffer cavity 21, make the stressing conditions of stop valve clack have obvious change, the pressure of liquid is resolved into positive force has increased the sealing force between stop valve clack and valve seat, thereby has improved sealability.
Described buffer part 211 is and is wholely set with sealing head 2.
By adopting technique scheme, buffer part 211 is wholely set with sealing head 2, can improve the intensity of stop valve clack.
Described sealing head 2 electroplating anticorrosion zinc layers.
By adopting technique scheme, in sealing head electroplating anticorrosion zinc layer, the working life that can improve stop valve clack.
