Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 and 2, the present embodiment provides a stainless steel angle seat valve, including a valve body 100 having an inlet and an outlet and a valve 101, wherein a valve rod 200 is disposed above the valve 101, and a valve core 300 for opening and closing the valve 101 is disposed at a lower end of the valve rod 200; a stop channel 102 engaged with the valve 101 is arranged on the valve body 100, and the valve core 300 is positioned in the stop channel 102; the side part of the cut-off channel 102 is also provided with a detection hole 103, and a plug 400 is arranged in the detection hole 103.
When the valve rod 200 is rotated, the valve rod 200 is withdrawn upwards relative to the valve 101, the valve element 300 is pulled upwards, the valve element 300 is separated from the valve 101, at this time, the valve 101 is in an open state, and liquid can enter the stop passage 102 from the inlet of the valve body 100 through the valve 101 and then flow out from the outlet of the valve body 100, as shown in fig. 2.
When the valve stem 200 is rotated in the reverse direction, the valve stem 200 moves downward to block the valve 101 with the valve body 300, and at this time, the valve 101 is in a closed state, and liquid cannot enter the stop passage 102 or flow out from the outlet of the valve body 100, as shown in fig. 3.
When the conditions such as the flow rate of liquid in the valve body 100 need to be detected, the plug 400 is opened, the detection device is screwed into the detection hole 103, the detection head of the detection device is positioned in the stop channel 102, and the liquid is contacted with the detection head when flowing through the stop channel 102, so that the detection can be carried out, and the detection precision is high.
Specifically, the plug 400 is a bolt, and the seal ring 500 is disposed in the detection hole 103.
The plug 400 is detachably arranged, so that different detection devices can be conveniently installed, and different detection of liquid in the valve body 100 can be conveniently carried out. Meanwhile, when detection is not needed, the plug 400 is used for blocking and sealing the detection hole 103, and internal liquid is prevented from leaking from the detection hole 103.
In this embodiment, the valve 101 is located between two openings of the valve body 100, and the blocking passage 102 is disposed obliquely to the valve body 100.
To facilitate the operation of the valve stem 200, a knob 600 is coupled to an upper end of the valve stem 200. The knob 600 is rotated to drive the valve rod 200 to rotate relative to the valve body.
Referring to fig. 2, a joint of a valve body 100 is provided on the valve body 100, and a lower end of the joint of the valve body 100 is screwed to the cut-off passage 102; the valve body 100 is provided with a through hole capable of accommodating the valve rod 200, and the valve rod 200 is movably arranged in the through hole.
In this embodiment, the through hole of the valve body 100 is a threaded hole, and the valve stem is threadedly connected to the through hole and is capable of moving relative to the valve body 100 by rotation.
Preferably, in this embodiment, the detection hole 103 is located below the joint of the valve body 100, and when it is necessary to install the detection device, the knob 600 is pulled to pull up the valve stem 200, and the detection is performed when the valve body 300 is separated from the valve 101. When the valve body 300 blocks the valve 101, liquid cannot enter the shut-off passage 102, and detection cannot be performed.
In order to prevent liquid from leaking from the gap between the valve stem 200 and the valve core 300, a sealing cavity 701 is formed inside the valve body 100, and the through hole is formed through the sealing cavity 701; a sealing packing 800 is disposed in the sealing cavity 701, and fills and seals a gap between the valve stem 200 and the sealing hole.
When a small amount of liquid enters the seal cavity 701 through the gap between the valve stem 200 and the bore, it contacts the packing 800 and is blocked from further extravasation.
Preferably, the sealing packing 800 includes a plastic sealing ring 810 and a rubber sealing ring 820, and the plastic sealing ring 810 and the rubber sealing ring 520 are alternately stacked in sequence to form a plurality of sealing packing.
Preferably, the plastic sealing ring 810 and the rubber sealing ring 820 are oil sealing rings with V-shaped cross sections, and the V-shaped opening faces the valve plug 300.
When liquid enters the sealing cavity 701 and contacts with the sealing packing 800, the liquid is blocked by the sealing packing 800, part of the liquid enters the V-shaped groove along the surface of the oil seal ring, and the two sides of the V shape are extruded, so that the oil seal ring, the valve rod 200 and the inner wall of the sealing cavity 701 are matched more tightly.
The upper end of the joint of the valve body 100 is provided with an opening, a joint cover 710 is arranged at the opening, and an avoidance hole 711 which can accommodate the valve rod 200 to pass through is arranged on the joint cover 710; a spring 900 is arranged in the joint of the valve body 100 to compress the sealing filler 800.
The upper end of the spring 900 abuts against the inner wall of the joint cover 710, and the lower end contacts and applies pressure to the uppermost oil seal ring, pressing the entire packing 800 downward. In the process of pressing down the oil seal ring, the inclination angles of the two inclined planes of the V-shaped groove are increased, and the inclined planes of the V-shaped groove are in interference fit with the inner walls of the valve rod 200 and the sealing cavity 701, so that the contact is tighter, and the sealing effect is better.
In this embodiment, a gasket 1 and a sealing cushion block 2 are further stacked and disposed below the sealing packing 800 in the sealing cavity 701.
The usage of this embodiment is the same as the angle seat valve in the prior art, and will not be described herein.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
