Problems solved by technology
The disadvantages of this kind of ball valve are: 1. The valve switch is not sensitive, and it is difficult to adapt to high-speed jet weaving; 2. The flow rate of this kind of ball valve is small, and it is difficult to adapt to heavy fabric weaving.
[0003] The applicant once proposed a one-way valve for water jet loom on August 29, 2008. The patent number is ZL200820163723.3. Although it can effectively solve the problem of water flow, the structure is relatively complicated and it is quite inconvenient to install and use

Embodiment Construction
[0016] Such as figure 1 , figure 2 As shown, the large-flow water jet loom check valve of the present invention includes a valve seat 3, a valve cover 1 with a water hole 7 is installed on the valve seat 3, and a gasket is sandwiched between the valve cover 1 and the valve seat 3 2. It is used to seal and block water. There is a cavity inside the valve seat 3. The movable valve core 4 is movably installed in the inner cavity of the valve seat 3, and can move up and down along the inner cavity wall of the valve seat 3. The bottom of the seat 3 is provided with several water holes 6 .
[0017] In the present invention, the movable spool 4 is mainly composed of a switch part 41 at the top, a connecting part 42 at the middle, and a mounting part 43 at the bottom. Tightly matched with the valve cover 1, the cross section of the switch part 41 is preferably arc-shaped, so as to achieve a better sealing effect. The connecting part 42 is in contact with the inner cavity wall of the...

The invention discloses a one-way valve of a high-flow water-spraying loom, belonging to the technical field of textile machineries and comprising a valve seat, wherein a valve cover with drain holes is installed on the valve seat. The one-way valve is characterized in that the valve seat is internally provided with a hollow cavity, a moving valve plug is movably arranged in the inner cavity of the valve seat and can move up and down under the guidance of the inner cavity wall of the valve seat, a plurality of drain holes are arranged at the lower part of the valve seat, the moving valve plug is mainly composed of a switch part, a connection part and an installation part, the switch part is matched with the drain holes of the valve cover, the connection part is in contact with the inner cavity wall of the valve seat, the contact face between the connection part and the valve seat is provided with a plurality of arc-shaped dents, a water flow channel is formed in a gap between the dents and the inner cavity wall of the valve seat, and a spring is sleeved on the installation part. The invention has the advantages of simple structure, convenient installation and use and flexible action and is applicable to the high-flow water-spraying looms.
Description
Technical field: [0001] The invention relates to a water-jet loom, in particular to a one-way valve for a large-flow water-jet loom, which belongs to the technical field of textile machinery. Background technique: [0002] The one-way valve of existing water-jet loom is common ball valve. The valve switch is placed in the concave spherical valve body through the ball. When there is no water pressure, the ball falls into the concave spherical valve body of the valve body. When there is water pressure in the water hole facing the valve cover, the water pressure pushes the ball away from the concave spherical valve. The water flows out from the gap between the sphere and the concave spherical valve body, flows out through the water hole at the bottom of the valve body, the valve opens, and when there is water pressure facing the water hole at the bottom of the valve body, the sphere is blocked by the water The water hole of the bonnet, the water is blocked, and the valve is cu...
