Detailed Description
Example 1
As shown in fig. 1, the present embodiment 1 provides a PP-R high flow stop valve, the main body part of which is a hollow T-shaped main pipe;
the T-shaped main pipe consists of a direct current pipe 100 and an operation pipe 110 which is protruded from the surface of the direct current pipe and forms a T-shaped right angle with the direct current pipe;
a flow part 200 located inside the straight pipe 100 and facing the operation pipe 110;
a first blocking member 400 connected to the lower edge of the operation pipe is provided inside the straight flow pipe at one side of the flow part 200 in the direction of the water inlet;
a second blocking member 300 connected to a tube wall having a position opposite to the operation tube at the other side of the flow part 200, that is, at a position opposite to the first blocking member 400;
under the action of the two blocking pieces, water flow entering the straight-flow pipe from the direction of the inlet indicated by an arrow cannot directly pass through the second blocking piece and flow out of the pipe body; similarly, the reverse water flow can not pass through the first blocking piece to flow out from the inlet, so that the effect of controlling the water flow in a single direction is achieved.
The flow part 200 has a flow hole 210;
under the action of the flow part 200, the first blocking member 400 and the second blocking member 300, in the case that the flow hole is not closed, the water flow entering from the inlet direction can only proceed along a fluid passage like an S-shape in the straight pipe;
the flow passage 200 has a ring-shaped seal 220 that is formed in a protruding manner on the surface facing the operation pipe 110 at a position near the edge of the flow passage hole 210.
The inner wall of the operation tube 110 has an internal thread 111 in which the flow control valve 10 with adjustable depth is installed;
the flow control valve 10 has a cylindrical shape with a twist grip 11 at an end thereof and an external thread 12 on an outer surface thereof, the external thread 12 being matched with the internal thread 111, and when the flow control valve 10 is installed in the operation tube 110, a tight fitting effect can be achieved.
In consideration of the case where a part of the male screw structure is soaked in water for a long period of time, the male screw and the female screw are coated with a waterproof, antirust or similar protective coating.
In addition, when it is desired to control the flow rate, it is only necessary to rotate the handle to control the flow rate control valve 10 away from or close to the flow hole 210.
The end of the flow control valve 10 is also provided with a raised annular structure 13;
the raised annular structure 13 is matched with the annular sealing element 220, and when the flow control valve 10 is tightly attached to the circulation hole in a rotating mode, the raised annular structure 13 is just attached to the annular sealing element 220, so that the effect of thoroughly blocking the circulation hole is achieved.
In addition, considering the phenomenon that a large amount of water flow gushes out or gushes in to cause turbulence, a plurality of flow guide structures are arranged on the inner surface of the straight-flow pipe, such as: a flow guiding inclined plane or arc-shaped surface 310 at the water flow inlet end, a flow guiding inclined plane or arc-shaped surface 320 at the water flow outlet end and the like. Similar flow directing structures may be provided at a plurality of corner locations within the tube, as desired for use.
Example 2
As shown in fig. 2, the present embodiment 2 provides another PP-R high flow stop valve, the main body of which is a hollow T-shaped main pipe;
the T-shaped main pipe consists of a direct current pipe 100 and an operation pipe 110 which is protruded from the surface of the direct current pipe and forms a T-shaped right angle with the direct current pipe;
a flow part 200 located inside the straight pipe 100 and facing the operation pipe 110;
a first blocking member 400 connected to the lower edge of the operation pipe is provided inside the straight flow pipe at one side of the flow part 200 in the direction of the water inlet;
a second blocking member 300 connected to a tube wall having a position opposite to the operation tube at the other side of the flow part 200, that is, at a position opposite to the first blocking member 400;
under the action of the two blocking pieces, water flow entering the straight-flow pipe from the direction of the inlet indicated by an arrow cannot directly pass through the second blocking piece and flow out of the pipe body; similarly, the reverse water flow can not pass through the first blocking piece to flow out from the inlet, so that the effect of controlling the water flow in a single direction is achieved.
The flow part 200 has a flow hole 210;
the inner surface of the flow hole 210 has an inclination angle 211, i.e. the flow hole has the effect of having a small inlet and a large outlet;
under the action of the flow part 200, the first blocking member 400 and the second blocking member 300, in the case that the flow hole is not closed, the water flow entering from the inlet direction can only proceed along a fluid passage like an S-shape in the straight pipe;
the flow passage 200 has a ring-shaped seal 220 that is formed in a protruding manner on the surface facing the operation pipe 110 at a position near the edge of the flow passage hole 210.
The inner wall of the operation tube 110 has an internal thread 111 in which the flow control valve 10 with adjustable depth is installed;
the flow control valve 10 has a cylindrical body portion, one end portion of which is provided with a twist grip 11, and an outer surface of which is provided with an external thread 12, the external thread 12 being matched with the internal thread 111, so that a close fit effect can be achieved when the flow control valve 10 is installed in the operation tube 110.
In consideration of the case where a part of the male screw structure is soaked in water for a long period of time, the male screw and the female screw are coated with a waterproof, antirust or similar protective coating.
The other end of the flow control valve 110 has a trapezoidal boss 14, the structure and size of the trapezoidal boss 14 are the same as those of the flow hole 210, and when the flow is required to be controlled, the flow control valve 10 is only required to be controlled to be far away from or close to the flow hole 210 by rotating the handle. Due to the fact that the sealing structure is provided with the trapezoid contact surface, the sealing structure is easier to position when being close to the circulation hole, deviation and handwriting are avoided, and the sealing effect can be better achieved in the sealing process from large to small.
The flow control valve 10 is also provided with a raised annular structure 13;
the raised annular structure 13 is matched with the annular sealing element 220, and after the trapezoidal platform 13 of the flow control valve 10 is completely attached to the inner space of the flow hole 210 in a rotating mode, the raised annular structure 13 is just attached to the annular sealing element 220, so that the effect of completely blocking the flow hole is realized.
In addition, considering the phenomenon that a large amount of water flow gushes out or gushes in to cause turbulence, a plurality of flow guide structures are arranged on the inner surface of the straight-flow pipe, such as: a flow guiding inclined plane or arc-shaped surface 310 and a flow guiding surface 410 at the water flow inlet end, a flow guiding inclined plane or arc-shaped surface 320 at the water flow outlet end and the like. Similar flow directing structures may be provided at a plurality of corner locations within the tube, as desired for use.
In the above embodiment, the sealing surface of the stop valve is provided with a step, so that sealing can be achieved without the need of a valve which is closed by applying a forced force like a common stop valve. Compared with the common high-flow stop valve, the high-flow stop valve has the advantages of reasonable structural design, good sealing performance and convenient manufacture and maintenance; the liquid resistance is small, and the valve can be used for cutting off or connecting a medium and can adjust the flow rate.
In addition, the stop valve also has the following characteristics:
(1) the stop valve structure is simpler than the gate valve, and the manufacture and the maintenance are both more convenient.
(2) The sealing surface is not easy to wear and scratch, the sealing performance is good, and the valve clack and the sealing surface of the valve body do not slide relatively when the valve is opened and closed, so that the wear and the scratch are not serious, the sealing performance is good, and the service life is long.
(3) When the stop valve is opened and closed, the stroke of the valve clack is small, so that the height of the stop valve is smaller than that of the gate valve, but the structural length of the stop valve is longer than that of the gate valve.
(4) The opening and closing torque is large, the opening and closing are laborious, and the opening and closing time is long.
(5) The fluid resistance is large, and the power consumption is large because the medium channel in the valve body is more tortuous.
(6) When the nominal pressure PN in the medium flowing direction is less than or equal to 16MPa, forward flow is generally adopted, and the medium flows upwards from the lower part of the valve clack; when the nominal pressure PN is more than or equal to 20MPa, the reverse flow is generally adopted, and the medium flows downwards from the upper part of the valve clack so as to increase the energy of the sealing element. When the stop valve is used, the medium of the stop valve can only flow in one direction, and the flow direction cannot be changed.
(7) The valve flap is often eroded when fully open.
The axis of the valve rod of the stop valve is vertical to the sealing surface of the valve seat. The valve rod has a relatively short opening or closing stroke and a very reliable cut-off action, so that the valve is suitable for cutting off or adjusting media and throttling.
