Technical Field
The utility model relates to the technical field related to needle valves, in particular to a needle valve with double-side feeding.
Background
The needle valve is a fine tuning valve, and the valve plug is in a needle shape and mainly used for adjusting the air flow. The fine tuning valve requires a gradual increase in valve port opening, with continuous fine tuning from closed to open maximum. The needle valve plug can achieve this function. Needle valve plugs are typically made of hardened steel needles, while valve seats are made of soft materials such as tin, copper, etc. The sealing between the valve needle and the valve seat is achieved by means of the tight fit of the conical surfaces of the valve needle and the valve seat, the conical surfaces are subjected to fine grinding, and the sealing between the valve rod and the valve seat is achieved by means of a corrugated pipe, but most of valve cores of the existing needle valves always receive pressure in one direction and fluid flushing force, and the valve cores are easy to deflect and lose efficacy, so that a needle valve with double-side feeding is particularly needed.
The needle valve is a common fluid conveying component, can realize quick, accurate and reliable control of fluid circulation/closing, and most of needle valves are provided with a fluid inlet and a fluid outlet, so that the valve core of the needle valve always receives pressure and fluid flushing force in one direction, and the valve core is easy to deflect and lose efficacy.
Disclosure of Invention
The utility model aims to provide a needle valve with double-side feeding, which solves the problems that most of needle valves proposed in the prior art are provided with a fluid inlet and a fluid outlet, and the valve core of the needle valve always receives pressure and fluid flushing force in one direction, and the valve core is easy to deflect and lose efficacy.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a needle valve of two side feeding, includes valve body, feed joint-, ejection of compact joint-, feed bin, needle, cylinder, copper core and end cap, feed joint-, have been seted up to one side surface of valve body, ejection of compact joint-, have been seted up to one side surface of valve body, the inboard surface mounting of valve body has the feed bin, the inboard surface mounting of feed bin has the needle, one side surface mounting of valve body has the cylinder, the inboard surface fixedly connected with copper core of ejection of compact joint-, one side surface mounting of valve body has the end cap.
Preferably, the outer wall of the plug is identical to the inner wall of the valve body in size.
Preferably, the shape and size of the feeding connector are consistent with those of the discharging connector.
Compared with the prior art, the utility model has the beneficial effects that: the needle valve with double-side feeding adopts a double-side feeding scheme, so that the pressure and the scouring force born by the valve core are in an equilibrium state. The valve core deflection is prevented, the service life and reliability of the needle valve are improved, fluid enters the valve body 1 from 1-1, two material flows are divided into two material flows along the circumferential direction in the valve body 1, the two material flows rotate 90 degrees along the circumferential direction, and after entering the valve body, the two material flows bypass 90 degrees and enter the inner cavity of the valve body in opposite directions, and the fluid has little influence on the valve needle due to symmetrical distribution. The valve needle is not easy to deflect, thus completing a needle valve with double-side feeding.
Drawings
FIG. 1 is a schematic view of the overall appearance structure of the present utility model.
In the figure: 1. a valve body; 1-1, a feeding connector; 1-2, a discharging connector; 2. a storage bin; 3. a valve needle; 4. a cylinder; 5. a copper core; 6. and (5) plugging.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, the present utility model provides a technical solution: the utility model provides a needle valve of two side feeding, including valve body 1, feed joint 1-1, discharging joint 1-2, feed bin 2, needle 3, cylinder 4, copper core 5 and end cap 6, feed joint 1-1 has been seted up to one side surface of valve body 1, discharging joint 1-2 has been seted up to one side surface of valve body 1, the inboard surface mounting of valve body 1 has feed bin 2, the inboard surface mounting of feed bin 2 has needle 3, one side surface mounting of valve body 1 has cylinder 4, the inboard surface fixedly connected with copper core 5 of discharging joint 1-2, one side surface mounting of valve body 1 has end cap 6, through valve body 1, feed joint 1-1, discharging joint 1-2, feed bin 2, needle 3, cylinder 4, copper core 5 and end cap 6's setting, when using to valve body 1 when needs, fluid gets into valve body 1 by 1-1, in the inside along the circumferencial direction of valve body 1, divide two flows, respectively along the circumferencial direction, 90 after the fluid gets into the valve body, the flow gets into the inner chamber around 90 degrees, the flow gets into with the opposite direction, because the influence of fluid to the needle is very little. The valve needle is not easy to deflect, thus completing a needle valve with double-side feeding.
Further, the outer wall size of the plug 6 is identical to the inner wall size of the valve body 1, and the valve body 1 can be better sealed through the arrangement of the plug 6.
Furthermore, the shape and the size of the feeding connector 1-1 are consistent with those of the discharging connector 1-2, and the valve body 1 can be better injected through the arrangement of the feeding connector 1-1.
Working principle: the fluid enters the valve body 1 from 1-1, is divided into two material flows along the circumferential direction in the valve body 1, rotates 90 degrees along the circumferential direction, bypasses 90 degrees after entering the valve body, and the two material flows enter the inner cavity of the valve body in opposite directions, so that the influence of the fluid on the valve needle is small due to symmetrical distribution. The valve needle is not easy to deflect, thus completing a needle valve with double-side feeding.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
