Abstract
The utility model discloses a hand-operated high pressure stop valve comprising a valve seat, wherein a first fluid port, a second fluid port and a sealing head are arranged on the valve seat, the sealing head controls on-off of the first and second fluid ports, the end of the sealing head is in cone shape, and a conical groove matching with the end of the sealing head is arranged on the first fluid port. The hand-operated high pressure stop valve has the advantages that 1, the sealing head utilizes a conical surface which is easier to be processed as a main seal of the stop valve, which is used for sealing through mechanical deformation after axial linear extrusion and can bear 10000psi pressure, 2, by the anti-rotation pushing engagement structure of the nut and the sealing head, the stop valve can normally operate just by small torque, and poor sealing and compressive damage to O-shaped rings caused by rotation can be avoided during the linear movement of the sealing head of the stop valve, 3, by utilizing the double-sealing structure, the utility model not only is simple in structure but also can realize leakage prevention.
Description
Technical field
The utility model relates to a kind of high-pressure stop valve.
Background technique
At present most high pressure manual stop valves all is to adopt spherical rigid seal structure, though a lot of advantages is arranged, reliable etc. such as sealing, it is high to exist processing and assembly precision to require, repair behind the sealing surface wear difficult, the more high shortcoming of cost.
The model utility content
The technical problems to be solved in the utility model provide a kind of simple in structure, with low cost, be easy to safeguard the high pressure manual stop valve.
In order to address the above problem, the utility model provides a kind of high pressure manual stop valve to comprise: valve seat, valve seat is provided with the first fluid mouth and second fluid flow port, also be provided with the sealing head that the control first fluid mouth and second fluid flow port are communicated with or disconnect on the described valve seat, the termination of described sealing head is taper, and described first fluid mouth is provided with the cone tank that described termination matches.
Preferably, but on the described valve body also helical rotation be provided with control described sealing head the locknut of shaft pertaining in straight line is inserted into described cone tank.
Preferably, also be provided with the dead man that the termination of described sealing head can be extracted in the described cone tank on the described sealing head.
Preferably, described locknut is provided with rotatable handle.
Preferably, also be provided with the O circle that is sealed and matched with described valve seat formation on the described sealing head.
The utlity model has following advantage:
1, the conical surface of the easier processing of sealing head termination employing of the present utility model seals by the mechanically deformation after the axial straight line extruding as the primary seal of stop valve, can bear the pressure up to 10000psi;
2, the anti-rotation of the utility model by locknut and sealing head promotes cooperating structure, only needs less moment just can make the stop valve regular event, and the stop valve sealing head can not cause poor sealing and squeezes bad O and enclose in the straight line moving process because of rotation;
3, it is not only simple in structure that the utility model adopts double sealing structure, but also can realize anti-leak.
Description of drawings
Fig. 1 is the utility model structural profile schematic representation;
Fig. 2 is the utility model perspective view.
Embodiment
As shown in Figure 1, 2, the utility model comprises: valve seat 1, valve seat 1 is provided with the first fluid mouth 6 and second fluid flow port 7, valve seat 1 is provided with control first fluid mouth 6 and second fluid flow port 7 is communicated with or the sealing head 2 of disconnection, the termination 21 of sealing head 2 is taper, and first fluid mouth 6 is provided with the cone tank 61 that termination 21 matches.
But on the valve body 1 also the helical rotation termination 21 axial straight lines that are provided with control sealing head 2 be inserted into the interior locknut 3 of cone tank 61, locknut 3 is provided with rotatable handle 5.Specifically be as shown in Figure 1, sealing head 2 is provided with boss 22, rotation locknut 3 along sealing head 2 axially to valve seat 1 in when mobile, locknut 3 leans boss 22, thus promotion sealing head 2 vertically straight line move, in being inserted into conical surface 61.Because sealing head 2 does not rotate, therefore in the straight line moving process, can not cause poor sealing and squeeze bad O circle because of rotation.In addition, the utility model promotes cooperating structure by the anti-rotation of locknut 3 and sealing head 2, only needs less moment just can make the stop valve regular event.
As shown in Figure 1, 2, also be provided with the dead man 4 that the termination 21 of sealing head 2 can be extracted in the cone tank 61 on the sealing head 2.In the time the termination 21 of sealing head 2 need being extracted from cone tank 61, counter-rotating locknut 3, make locknut 3 along sealing head 2 axially withdraw from valve seat 1, by dead man 4 termination 21 of sealing head 2 is extracted from cone tank 61 then.
As shown in Figure 1, also be provided with the O circle 8 that is sealed and matched with valve seat 1 formation on the sealing head 2.Adopt the double sealing structure of sealing of O circle and sealing head 2 sealings, not only simple in structure, but also can realize anti-leak.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
