Technical Field
The invention relates to a valve, in particular to a multi-hole flow-regulating shut-off valve, which belongs to the technical field of valve.
Background
Valves are control components in fluid transfer systems, with the functions of cut-off, regulation, diversion, prevention of counter-flow, pressure stabilization, division and overflow pressure relief. Valves include a butterfly valve, ball valve, gate valve, stop valve, throttle valve, shut-off valve and the like. In particular, the shut-off valve with flow regulation requirements needs to regulate the water flow when it is opened and closed. It is very important to use the flow- regulating shut-off valve if the water flow needs to be adjusted to half of the water flow when the valve is in a fully open state.
In practical use, the traditional flow-regulating shut-off valve is controlled by a single water channel and a single ball. and the opening and closing of the valve are easily controlled. However, the rotation angle of the ball needs to be changed by rotating the stem during flow regulation. This method only plays the role of flow regulation, and it is difficult to regulate the water flow to half of the water flow when the valve is in a fully open state, so the accuracy of flow regulation is greatly reduced. In this regard, a multi-hole flow-regulating shut-off valve should be designed.
Summary of the Invention
The invention provides a multi-hole flow-regulating shut-off valve, which can solve the above-mentioned problems that it is difficult for the valve with a single water channel and a single ball to regulate the water flow to half of the water flow when the valve is in a fully open state, so the accuracy of flow regulation is greatly reduced.
To solve the above-mentioned technical problems. the invention provides the following technical solution:
A multi-hole flow-regulating shut-off valve, comprising a valve body, wherein, a water inlet is fixed at one end of the valve body, a water outlet is fixed at the end of the valve body away from the water inlet, a first stem is installed in a rotatable way at the top end of the valve body, a first knob is fixed at the end of the first stem away from the valve body, a second stem is installed in a rotatable way at the bottom end of the valve body, a second knob is fixed at the end of the second stem away from the valve body, a water channel is formed in the valve body, the water inlet is communicated with the water outlet through a water channel, a solid part is welded at the inner wall of the water channel, two circular through holes are formed symmetrically in the solid part in parallel, a ball is fixed at the end of the first stem away from the first knob, a ball is fixed at the end of the second stem away from the second knob, both balls are installed in a rotatable way in the correspondingly arranged circular through holes. a ball hole is formed in each ball, and both of the two ball holes are arranged in parallel with the correspondingly arranged circular through holes.
As a preferred technical solution of the invention, stoppers are fixed symmetrically on the first stem and the second stem in the valve body, and the two stoppers are embedded in a rotatable way in the valve body.
As a preferred technical solution of the invention, two seals are fixed symmetrically in each of the two circular through holes, and the two seals in the same circular through holes are arranged at the opposite sides of the balls.
As a preferred technical solution of the invention, the first stem. the second stem and the two balls are on the same vertical axis.
As a preferred technical solution of the invention, the two balls are of the same specification, and the two ball holes are of the same diameter.
The invention has the following beneficial effects: The invention provides a multi-hole flow- regulating shut-off valve which has the characteristic of accurate flow regulation. In specific use, compared with the traditional flow-regulating valve, the multi-hole flow-regulating shut-off valve has the following arrangements:
A solid part is fixed in the water channel of the valve body, and two circular through holes with an equal diameter are formed in the solid part. By rotating the first knob and the second knob, the two balls can be driven to rotate in the correspondingly arranged circular through holes, thus controlling the opening and closing of the two circular through holes. When both of the two circular through holes are regulated to a closed state, the valve is fully closed. When both of the two circular through holes are regulated to the open state, the valve is fully open, and the flow rate is maximized.
When one circular through hole is open and the other circular through hole is closed, the flow is half of the flow when the valve is fully open, which facilitates more accurate flow regulation and greatly improves the accuracy of flow regulation.

Detailed Description of the Preferred Embodiments
The technical solution in the embodiments of the invention is described clearly and completely below in combination with the drawings in the embodiments of the invention.
Obviously, the embodiments described are only a part but not the whole of the embodiments of the invention. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without any creative work are within the protection scope of the invention.
Embodiment
As shown in FIG. 1-3, the invention provides a multi-hole flow-regulating shut-off valve, comprising a valve body 1, wherein, a water inlet 4 is fixed at one end of the valve body |, a water outlet 7 is fixed at the end of the valve body 1 away from the water inlet 4, a first stem 3 is installed in a rotatable way at the top end of the valve body 1, a first knob 2 is fixed at the end of the first stem 3 away from the valve body 1, a second stem 5 is installed in a rotatable way at the bottom end of the valve body 1, a second knob 6 is fixed at the end of the second stem 5 away from the valve body 1, a water channel 13 is formed in the valve body 1, the water inlet 4 is communicated with the water outlet 7 through a water channel 13, a solid part 11 is welded at the inner wall of the water channel 13, two circular through holes 12 are formed symmetrically in the solid part 11 in parallel, a ball 14 is fixed at the end of the first stem 3 away from the first knob 2, a ball 14 is fixed at the end of the second stem 5 away from the second knob 6, both balls 14 are installed in a rotatable way in the correspondingly arranged circular through holes 12, a ball hole 15 is formed in each ball 14, and both of the two ball holes 15 are arranged in parallel with the correspondingly arranged circular through holes 12. The first stem 3 is driven to rotate through the first knob 2, the second stem 5 is driven to rotate through the second knob 6, and then the two balls 14 are driven to rotate. When the ball holes 15 in the two balls 14 are in parallel with the correspondingly arranged circular through holes 12, water can enter from the water inlet 4 into the valve body 1 and come out from the water outlet 7. At this time, the water flow reaches the maximum value. When the ball holes 15 in the two balls 14 are in vertical crossing with the correspondingly arranged circular through holes 12, water cannot pass through the valve body 1. When one ball hole 15 is in parallel with the correspondingly arranged circular through hole 12 while the other ball hole 15 is in vertical crossing with the correspondingly arranged circular through hole 12, water can still pass through the valve body 1 at this time, and the flow at this time 1s half of the maximum water flow.
Two seals 17 are fixed symmetrically in each of the two circular through holes 12, and the two seals 17 in the same circular through hole 12 are arranged at the opposite sides of the balls 14.
The sealing performance of connection between the two balls 14 and the correspondingly arranged circular through holes 12 can be ensured by four seals 17, effectively avoiding water leakage which will affect the performance of the valve. The first stem 3, the second stem 5 and the two balls 14 are on the same vertical axis. The two balls 14 are of the same specification, the two ball holes 15 are of the same diameter. Stoppers 16 are fixed symmetrically fixed on the first stem 3 and the second stem 5 in the valve body 1, and the two stoppers 16 are embedded in a rotatable way in the valve body 1. The first stem 3 and the second stem 5 can be stopped through the stoppers 16 embedded in arotatable way in the valve body 1 to prevent the first stem 3 and the second stem 5 from driving the two balls 14 to rotate in the process of rotation and prevent the two balls 14 from being disengaged from the original position and further affecting the water stopping effect.
Specifically, when in use, the operator can hold the first knob 2 and the second knob 6, rotate the first knob 2 and the second knob 6 to drive the first stem 3 and the second stem 5, and then the two balls 14 are driven to rotate. When the ball holes 15 are in vertical crossing with the circular through holes 12, the circular through holes 12 are in a closed state, so that water can be stopped.
When the ball holes 15 and the circular through holes 12 are in a parallel superposition state, the circular through holes 12 are in an open state, so that water can enter from the water inlet 4, pass through the water channel 13 in the valve body 1, and finally come out from the water outlet 7. As two circular through holes 12 are formed in the solid part 11, when the operator regulates and controls the valve, the valve is fully closed with the two circular through holes 12 in a closed state, which effectively plays the role of complete cut-off. When both of the two circular through holes 12 are in an open state, the valve is fully open to ensure the maximum flow. When one circular through hole 12 is in an open state and the other circular through hole 12 is in a closed state, water can still pass through the valve. But at this time, the flow rate is half of flow when the valve is in a fully open state, so that the flow of the valve can be effectively regulated. When in use, the valve avoids the drawback that it is difficult to accurately control the rotation angle of the ball 14 and greatly improves the accuracy of flow regulation as compared with the traditional valve which has a single channel and a single ball 14 only and which changes the water flow by adjusting the rotation angle ofthe ball 14.
Though the embodiments of the invention are given and described, those skilled in the art may understand that various changes, modifications, substitutions and variations of these embodiments could be made thereto without departing from the principles and spirits of the invention, and the scope of the invention is defined by the claims attached and their equivalents.
