a first through hole transversely penetrating through the piston is formed in the position, close to the small opening end, of the piston; a second through hole is formed in the piston along the longitudinal direction, one end of the second through hole is communicated with the first through hole, and the other end of the second through hole penetrates through the piston; the pressure cap is provided with a vent hole communicated with the accommodating cavity.
Further, press the cap with press and be equipped with first sealing washer between the big open end.
Furthermore, the small opening end is provided with a convex part which is convex inwards and is propped against the piston.
Furthermore, the middle section cover of piston is equipped with the second sealing washer, the holding chamber corresponds the protruding convex wall that is equipped with of the interlude of piston, the second sealing washer supports on the convex wall.
Further, the piston is close to one pot head of cap is equipped with the third sealing washer, just the third sealing washer supports on the inner wall in holding chamber.
Further, a fourth sealing ring is installed at one end, far away from the valve body, of the pressure cap.
Compared with the prior art, the utility model discloses a container high-pressure valve is through setting up the piston activity in the valve body to make the piston need not to change the diaphragm after using, effectively save a large amount of manpowers and time.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings, there is shown in the drawings,
FIG. 1: the utility model discloses the schematic diagram of container high-pressure valve.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
As shown in fig. 1, the high-pressure valve for a vessel of the present invention includes a valve body 1, a piston 2, and a pressure cap 3; the cap 3 is detachably mounted to one end of the valve body 1, and the piston 2 is movably mounted in a space defined by the valve body 1 and the cap 3.
The method specifically comprises the following steps: the inside of valve body 1 is equipped with both ends open-ended holding chamber 101, and holding chamber 101 includes large opening end 102 and little open end 103, and the cap 3 is installed in large opening end 102, and 1 movable mounting of valve body is in holding chamber 101, and the maximum external diameter of valve body 1 is greater than the diameter of little open end 103, avoids valve body 1 to deviate from in holding chamber 101. Further, a first seal ring 4 is interposed between the cap 3 and the large opening end 102; the small opening end 103 is provided with a convex part 104 which is inwards protruded and is propped against one end of the piston 2; a spring 5 is pressed between the other end of the piston 2 and the cap 3.
In addition, the middle section cover of piston 2 is equipped with second sealing washer 6, and the protruding wall 105 that is equipped with is corresponding to the interlude of piston 2 to holding chamber 101, and second sealing washer 6 supports on protruding wall 105. One pot head that piston 2 is close to cap 3 is equipped with third sealing washer 7, and third sealing washer 7 supports on the inner wall in holding chamber 101.
Besides, a first through hole 201 transversely penetrating through the piston 2 is formed at the position of the piston 2 close to the small opening end 103; and the piston 2 is provided with a second through hole 202 along the longitudinal direction, one end of the second through hole 202 is communicated with the first through hole 201, and the other end penetrates through the piston 2. The vent 301 of intercommunication holding chamber 101 is seted up to cap 3, and cap 3 is far away from the one end of valve body 1 and is installed fourth sealing washer 8. In this embodiment, the first seal ring 4, the second seal ring 6, the third seal ring 7, and the fourth seal ring 8 are all nitrile rubber rings, and are all O-shaped seal rings.
To sum up, the utility model discloses a container high-pressure valve is through setting up piston 2 activity in valve body 1 to make piston 2 need not to change the diaphragm after using, effectively save a large amount of manpowers and time.
As long as the idea created by the present invention is not violated, various different embodiments of the present invention can be arbitrarily combined, and all the embodiments should be regarded as the content disclosed by the present invention; the utility model discloses an in the technical conception scope, carry out multiple simple variant and different embodiments to technical scheme and go on not violating the utility model discloses the arbitrary combination of the thought of creation all should be within the protection scope.
