Technical field
The utility model relates to a kind of control valve for fluids based on metallic seal.
Background technique
Control valve for fluids is mainly realized the control to the high-pressure liquid pipeline, and the function that has conducting and end has good sealing property when ending.At present, control valve for fluids mainly uses spherical valve core sealing and conical surface seal spool.When adopting spherical valve core sealing or conical surface seal spool, spool orders about down in driving force, closely contacts with valve body, reaches the purpose of sealing.When adopting spherical valve core sealing or conical surface seal spool, spool contact with valve body to line contacts, and when impurity falls between, can cause sealing defective tightness and produces leakage; In addition, under the situation excessive to valve core driving force, the line contact sealing between spool and the valve body is damaged easily.
The model utility content
The technical problems to be solved in the utility model provides a kind of control valve for fluids reliable, that seal arrangement is difficult for being damaged that seals.
In order to address the above problem, the utility model provides a kind of control valve for fluids based on metallic seal, comprises valve body and spool, and spool is installed in the inner chamber that valve inner offers; The flow of liquid inlet and the liquid flowing outlet that are conducted with described inner chamber are set on described valve body, it is stifled to be arranged with fixing seal in the described flow of liquid inlet, and described spool is provided with practises physiognomy with the stifled end face of described fixing seal that the described flow of liquid of may command that contact enters the mouth and the elastic packing conducting structure of liquid flowing outlet conducting or disconnection.
Preferably, described flow of liquid inlet is 2, and described flow of liquid inlet is symmetricly set on the described valve body, all is arranged with described fixing seal in described 2 flow of liquid inlet and blocks up.
Preferably, described spool is provided with fluid passage, and described elastic packing conducting structure is arranged on the position of offering described fluid passage on the described spool.
Preferably, described elastic packing conducting structure comprises that the T type sealing that cooperatively interacts is stifled and ring packing is stifled, described ring packing is stifled be sleeved on described T type sealing stifled on, in described T type sealing stifled and ring packing stifled relatively to end face between also be arranged with seal ring.
The utlity model has following advantage:
1, the utility model adopts the metal end face seal, and area of contact is big between spool and the valve body, and its sealability is better, more stable;
2, the utility model adopts the metal end face seal, be to realize the control valve conducting and end by the slip between the face, remaining between the sealing surface and contacting, therefore when sliding, uncleanly thing in the fluid can be turned down, guarantee the cleaning between the seal face, realize control unclean fluid;
3, the utility model adopts the elastic packing conducting structure, has played buffering, self-adjusting effect, has significantly reduced the wearing and tearing of metal end face, has guaranteed the sealability of control valve for fluids;
4, the utility model adopts the T type sealing cooperatively interact stifled and ring packing is stifled, and sealing is reliable, installs, dismounting is convenient;
5, the utility model adopts a plurality of seal ring sealings, makes that the utility model sealing is more reliable.
Description of drawings
Below in conjunction with accompanying drawing mode of execution of the present utility model is described further:
Fig. 1 show the utility model based on the control valve for fluids of metallic seal by the time structural representation;
Structural representation when Fig. 2 shows the utility model based on the control valve for fluids conducting of metallic seal.
Embodiment
As shown in Figure 1 and Figure 2, the utility model provides a kind of control valve for fluids based on metallic seal, comprises valve body 1 and spool 2, and spool 2 is installed in the inner chamber of offering valve body 1 inside 10; The flow of liquid inlet 31 and the liquid flowing outlet 11 that are conducted with inner chamber 10 are set on valve body 1, it is stifled 4 to be arranged with fixing seal in the flow of liquid inlet 31, and spool 2 is provided with the practise physiognomy may command flow of liquid that contact of the end face of fixing seal stifled 4 and enters the mouth 31 and the elastic packing conducting structure 9 of liquid flowing outlet 11 conductings or disconnection.
The utility model adopts the metal end face seal, and area of contact is big between spool 2 and the valve body 1, and its sealability is better, more stable; The utility model adopts the metal end face seal, be to realize the control valve conducting and end by the slip between the face, remaining between the sealing surface and contacting, therefore when sliding, uncleanly thing in the fluid can be turned down, guarantee the cleaning between the seal face, realize control unclean fluid.
Flow of liquid inlet 31 is 2, and flow of liquid inlet 31 is symmetricly set on the valve body 1, all is arranged with fixing seal stifled 4 in 2 flow of liquid inlets 31.Spool 2 is provided with fluid passage 22, and elastic packing conducting structure 9 is arranged on the position of offering fluid passage 22 on the spool 2.Elastic packing conducting structure 9 comprises that the T type sealing stifled 5 that cooperatively interacts and ring packing are stifled 6, and ring packing stifled 6 is sleeved in the T type sealing stifled 5, T type sealing stifled 5 and ring packing stifled 6 relatively to end face between also be arranged with seal ring 8.
The utility model adopts elastic packing conducting structure 9, has played buffering, self-adjusting effect, has significantly reduced the wearing and tearing of metal end face, has guaranteed the sealability of control valve for fluids; The utility model adopts the T type sealing stifled 5 cooperatively interact and ring packing stifled 6, and sealing is reliable, installs, dismounting is convenient; The utility model adopts a plurality of seal ring sealings 41,21, makes that the utility model sealing is more reliable.
Below the utility model is elaborated:
The utility model based on the seal face of the control valve for fluids of metallic seal be fixing seal stifled 4 with T type sealing stifled 5 between end face, fixing seal stifled 4 and ring-like sealing stifled 6 between end face and the sealing of T type is stifled 5, the 6 end faces compositions that contact with seal ring 8 are blocked up in ring-like sealing.In the present embodiment, seal ring is the O RunddichtringO.
