As a further improvement of the utility model, the valve clack is formed by combining a cylinder and a cone, the cone is coaxially fixed on the lower end face of the cylinder, the upper end face of the cylinder is connected with the valve rod, when the valve clack descends, the side face of the cylinder blocks the left channel, and the lower end of the cone blocks the right channel.
As a further improvement of the utility model, the valve rod comprises an inner valve rod and an outer valve rod, the outer valve rod is connected to the valve body in a threaded manner, the inner valve rod is arranged in the outer valve rod in a penetrating manner and is connected with the outer valve rod in a threaded manner, and the lower end of the inner valve rod is connected with the valve clack.
As a further improvement of the utility model, the upper end of the valve rod is fixedly connected with a handle, and one end of the handle is provided with a tool groove for inserting an external tool.
The valve has the beneficial effects that through the arrangement of the circulating channels formed by the left channels and the right channels which are staggered up and down, the effect of reducing the flow rate of liquid flowing through the valve body can be effectively realized, and the problem of larger valve clack abrasion caused by too fast liquid flow rate is effectively avoided.
Drawings
Fig. 1 is an overall construction view of the high pressure needle valve of the present utility model.
Detailed Description
The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.
Referring to fig. 1, a high-pressure needle valve of this embodiment includes valve clack 91 and valve body 92 and valve rod 94, valve rod 94 and valve clack 91 linkage to drive valve clack 91 and go up and down in valve body 92, circulation passageway 93 has been seted up in the valve body 92, circulation passageway 93 is formed by left passageway and right passageway combination, and left passageway and right passageway are crisscross setting from top to bottom, connect through a valve clack passageway between, valve clack 91 goes up and down in the valve clack passageway to seal or open left passageway and right passageway, through the combined action of left passageway and right passageway of crisscross from top to bottom, can effectually realize carrying out the deceleration to the high-pressure liquid that flows, reduce the wearing and tearing to valve clack 91, increase life.
As a specific implementation manner of improvement, the valve clack 91 is formed by combining a cylinder and a cone, the cone is coaxially fixed on the lower end face of the cylinder, the upper end face of the cylinder is connected with the valve rod 94, when the valve clack 91 descends, the side face of the cylinder plugs the right channel, the lower end of the cone plugs the left channel, through the arrangement of the structure, the conical surface of the cone contacts with high-pressure liquid in the opening process, so that the abrasion can be effectively reduced, and in addition, the conical surface structure mode is adopted, and under the condition of certain abrasion, the tightness of the switch valve can be ensured by utilizing the mode that the integral valve clack 91 descends a little again.
As an improved specific embodiment, the valve rod 94 includes an inner valve rod 941 and an outer valve rod 942, the outer valve rod 942 is screwed on the valve body 92, the inner valve rod 941 is threaded in the outer valve rod 942 and is connected with the outer valve rod 942 by screw, and the lower end is connected with the valve clack 91, so that the effect of double adjustment can be achieved, and when the valve clack 91 wears, the tightness in the valve opening and closing process can be effectively ensured by adjustment.
As a modified specific embodiment, the upper end of the valve rod 94 is fixedly connected with a handle 95, one end of the handle 95 is provided with a tool slot for an external tool to insert, the torque for screwing the valve rod 94 can be effectively increased through the arrangement of the handle 95, and the torque for screwing the valve rod 94 can be further increased through the arrangement of the tool slot in a tool inserting manner.
In summary, the high-pressure needle valve of the present embodiment can effectively reduce the flow velocity flowing through the valve body 92 by forming the flow passage 93 by the left passage and the right passage which are staggered up and down, thereby effectively reducing the wear of the valve flap 91.
