This take through stop valve of pressure release function, including the valve body, the removal hole that is linked together with the valve body is inside seted up to the lower surface of valve body, the inside swing joint in removal hole has the ejector pin, the bottom fixedly connected with layer board of ejector pin, the last fixed surface of layer board is connected with the spring, the top of spring and the bottom fixed connection of valve body, and the pressure release hole that is linked together with the valve body is inside is seted up to the lower surface of valve body. This take through stop valve of pressure release function, through removing the hole, a spring, the layer board, the ejector pin, the horizontal pole, the sealed cowling, the sealing ring, supplementary ring and the mutual cooperation between the pressure release hole, reach and to release the water of end of intaking before the open and close valve, make and reduce water pressure, provide laborsaving effect for the switching valve from this, solved current through stop valve when closing and opening, because the end of intaking has water pressure, thereby the problem that can make when the switching valve more hard.
Description
Technical Field
The utility model relates to the technical field of valves, specifically be a take direct stop valve of pressure release function.
Background
The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so when the valve is closed, pressure must be applied to the valve clack to force the sealing surface not to leak. When the medium enters the valve from the lower part of the valve clack, the resistance to be overcome by the operating force is the friction force between the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod buckling can occur. The connection mode is divided into three types: flange connection, screw thread connection and welding connection. After the self-sealing valve appears, the medium flow direction of the stop valve is changed to enter the valve cavity from the upper part of the valve clack, at this time, under the action of medium pressure, the force for closing the valve is small, the force for opening the valve is large, and the diameter of the valve rod can be correspondingly reduced. Meanwhile, under the action of a medium, the valve in the form is also tighter, and when the existing straight-through stop valve is closed and opened, the water inlet end has water pressure, so that the valve is opened and closed more difficultly.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a take direct stop valve of pressure release function has solved current direct stop valve when closing and opening, because the end of intaking has water pressure to the more hard problem when can make the switching valve.
Technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a take through stop valve of pressure release function, includes the valve body, the removal hole that is linked together with the valve body is inside is seted up to the lower surface of valve body, the inside swing joint that removes the hole has the ejector pin, the bottom fixedly connected with layer board of ejector pin, the last fixed surface of layer board is connected with the spring, the top of spring and the bottom fixed connection of valve body, the pressure release hole that is linked together with the valve body is inside seted up to the lower surface of valve body, the inner diapire overlap joint of valve body has the sealing ring, the last fixed surface of sealing ring is connected with the sealed cowling, fixedly connected with horizontal pole between the left and right sides inner wall of sealing ring, the lower surface of horizontal pole and the top fixed connection of ejector pin.
Furthermore, the outer surface of the sealing ring is fixedly connected with an auxiliary ring, and the lower surface of the auxiliary ring is in lap joint with the inner wall of the valve body.
Furthermore, the number of the springs is two, and the two springs are symmetrically arranged by using the central axis of the supporting plate.
Furthermore, the number of the pressure relief holes is two, and the two pressure relief holes are symmetrically arranged by using the central axis of the sealing ring.
The utility model provides a take direct stop valve of pressure release function. The method has the following beneficial effects:
this take through stop valve of pressure release function, through removing the hole, a spring, the layer board, the ejector pin, the horizontal pole, the sealed cowling, the sealing ring, mutually support between supplementary ring and the pressure release hole, it can release the water of end of intaking before the open and close valve to reach, make and reduce water pressure, provide laborsaving effect for the open and close valve from this, solved current through stop valve when closing and opening, because the end of intaking has water pressure, thereby the problem that can make when the open and close valve more hard.
