Description
Technical Field
The utility model relates to an air regulation valve field specifically is an airtight governing valve of amount of wind of preventing leaking.
Background
At present, air volume adjusting valves arranged on air supply, air return, air exhaust and fresh air system pipelines in the domestic air purification industry and the ventilation industry have the phenomenon of air volume leakage, so that the energy consumption of system operation is wasted, and the production cost is increased; in addition, some industries need to discharge organic solvent in the production process, but the air volume regulating valve arranged on the organic solvent exhaust pipeline has a leakage phenomenon, and when the organic solvent is gathered to a certain concentration in a specific environment, explosion accidents and personal poisoning accidents can occur; therefore, a leakage-proof air quantity closed regulating valve is needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem of the prior art, the utility model provides a prevent airtight governing valve of amount of wind of leakage, concrete content is as follows:
a leakproof air volume closed regulating valve comprises a rectangular frame shell, a valve leaf arranged in the rectangular frame shell, a valve seat detachably arranged outside the rectangular frame shell, a valve rod connecting the valve leaf and the valve seat, and a transmission mechanism connecting the valve rod; the sealing device also comprises a first sealing ring and a second sealing ring; the rectangular frame shell and the valve seat are respectively provided with a first positioning hole and a second positioning hole at corresponding positions; the valve rod can be matched with the first positioning hole and the second positioning hole to connect the rectangular frame shell, the valve seat and the transmission mechanism; the first sealing ring is sleeved on the valve rod; the valve seat can press the first sealing ring on the rectangular frame shell to block the first positioning hole; the second sealing ring is sleeved on the valve rod; the transmission mechanism can press the second sealing ring on the valve seat to block the second positioning hole.
Further, the valve seat is detachably connected with the rectangular frame shell through a threaded bolt.
Further, the valve seat is arranged above the rectangular frame shell; the second sealing ring is arranged above the valve seat; the transmission mechanism is arranged above the second sealing ring.
Furthermore, a valve cover is arranged above the transmission mechanism.
Has the advantages that:
the first sealing ring is sleeved on the valve rod and pressed on the rectangular frame shell by the valve seat, so that a gap left when the valve rod is matched with the first positioning hole is sealed by the first sealing ring; the second sealing ring is sleeved on the valve rod and pressed on the valve seat by the transmission mechanism, so that the second sealing ring seals a gap left when the valve rod is matched with the second positioning hole; when the air volume adjusting valve works, the air is effectively prevented from leaking due to the gap left between the first positioning hole and the second positioning hole when the air volume adjusting valve is matched with the valve rod.
Drawings
FIG. 1 is a schematic view of an embodiment;
FIG. 2 is an enlarged view taken at A in FIG. 1;
wherein: 1. the valve comprises a rectangular frame shell, 11 parts of a first positioning hole, 2 parts of a valve leaf, 3 parts of a valve seat, 31 parts of a second positioning hole, 4 parts of a valve rod, 5 parts of a transmission mechanism, 6 parts of a valve cover, 7 parts of a first sealing ring and 8 parts of a second sealing ring.
Detailed Description
One of the embodiments of the present invention is as follows:
a leakproof air volume closed regulating valve comprises a rectangular frame shell 1, a valve leaf 2, a valve seat 3, a valve rod 4, a transmission mechanism 5, a valve cover 6, a first sealing ring 7 and a second sealing ring 8.
The rectangular frame shell 1 is integrally square, and a square valve leaf 2 is arranged in the rectangular frame shell; the upper surface of the outer side of the rectangular frame shell 1 is provided with a valve seat 3; the valve seat 3 is connected with the rectangular frame shell through a bolt; a first positioning hole 11 and a second positioning hole 31 are respectively arranged at corresponding positions on the rectangular frame shell 1 and the valve seat 3 for the valve rod 4 to pass through; the valve rod 4 passes through the first positioning hole 11 and the second positioning hole 31 and is connected with the valve leaf 2. The valve seat 3 is provided with a transmission mechanism 5; the transmission mechanism 5 is provided with a valve cover 6; the transmission mechanism 5 and the valve cover 6 are both connected with the valve rod 4. After the first positioning hole 11 and the second positioning hole 31 are engaged with the valve stem 4, there may be a gap, causing leakage. In order to solve the leakage problem, a first sealing ring 7 is sleeved on the valve rod 4; the first sealing ring 7 is positioned outside the rectangular frame shell 1, the valve seat 3 presses the first sealing ring 7 on the rectangular frame shell 1 to block a gap, and the problem that the gap exists at the position of the second positioning hole 31 to cause leakage when the rectangular frame shell 1 is connected with the valve rod is solved; the valve rod 4 is also sleeved with a second sealing ring 8; the second sealing ring 8 is pressed on the valve seat 3 by the transmission mechanism 5, and the problem of leakage caused by a gap existing at the position of the first positioning hole 11 when the valve seat 3 is connected with the valve rod is solved by blocking the gap. Further, the first sealing ring 7 and the second sealing ring 8 are made of a material having elasticity, such as rubber.
