Description

Magnetic locking gate valve

Technical Field

The utility model belongs to the technical field of the valve, a gate valve is related to, especially, relate to a magnetism locking gate valve.

Background

In daily life, the opening height of the magnetic locking valve is not large, the magnetic locking valve is convenient to open, can be opened remotely, and is convenient to maintain, so that the magnetic locking valve is widely used. The magnetic locking valve in the existing market has the defects that the connection strength of a magnetic locking structure for locking the valve rod is not high enough, and the valve body is easily opened by external force to be damaged. And the magnetic locking can not be well used in a pipeline with large flow rate. The valve body is required to have higher integral structural strength due to the fact that larger water flow impact force can be generated in a large-flow pipeline. Especially, when the magnetic locking valve is used on a water pipe in front of a meter, the strength of the structure locking structure of the magnetic locking valve is not enough, so that a user intentionally defaulting water charge can easily detach the valve cap maliciously to control the opening and closing of the valve, and unnecessary loss is caused. If the valve cap is fixedly connected with the valve rod directly at one time, for example, the valve rod and the valve cap are provided with pin holes at the side direction, and then the connecting pin is inserted, the pin is difficult to be detached after entering the pin hole. The valve cap which is possibly damaged under the condition of gas burst failure cannot be detached by users, so that the whole valve body is scrapped, and the cost for replacing the magnetic locking valve is greatly increased compared with the cost of the conventional valve body. And when the valve is damaged or the valve cap is partially damaged by a conventional user, the valve can be replaced only by replacing the whole valve, so that the cost is increased linearly. Therefore, the problem to be solved is that we are not reluctant to solve the problem.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a magnetic locking gate valve. The magnetic locking valve solves the technical problems that a common magnetic locking valve is low in safety and inconvenient to maintain.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a magnetism locking gate valve, includes that the upper end is fixed with the valve body of disk seat, is equipped with in the disk seat can circumferential direction's valve rod and valve rod upper end expose outside the disk seat, its characterized in that, the disk seat up end is equipped with the valve cap, the valve rod upper end is square and is equipped with the screw hole on the valve rod up end, the valve cap lower extreme is equipped with the square groove that matches with the valve rod, and the valve rod upper end is located the square groove and forms the side direction with the square groove cell wall and support, the valve cap upper end is equipped with runs through the valve cap and fixes with screw hole threaded connection, and theftproof screw up end is equipped with two and is sectorial and symmetrical arch each other, forms two mutual symmetrical fan-shaped grooves between arch and the arch, and the disk seat up end has seted up four column slots around the valve rod, is equipped with the gliding cylindric lock, the magnetic steel is fixed in the positioning hole, and the upper end of the valve cap can be detachably fixed with a hand wheel which can enable the cylindrical pin to always keep leaning against the bottom of the cylindrical groove.

The valve cap forms the side direction through square groove and valve rod upper end and supports and keep off and can drive the valve rod to rotate together when making valve cap circumferential direction. The setting of antitheft screw links into an organic whole with valve cap and valve rod for can only dismantle through corresponding instrument when dismantling or installing the valve cap, make the security of valve cap installation obtain promoting. The theftproof screw up end is equipped with two and is sectorial and mutual symmetrical arch, forms two mutual symmetrical fan-shaped grooves between arch and the arch, sets up like this and can only use the instrument that corresponds with two fan-shaped grooves and just can rotate the theftproof screw, has avoided under many domestic conventional instruments and the possibility of matcing, and the security obtains promoting. In addition, due to the connection mode, when the valve cap is damaged accidentally and needs to be replaced, the valve cap can be replaced only by disassembling the valve cap through a special tool, the problem of cost increase caused by directly replacing the whole valve body like a conventional magnetic locking valve is solved, and the valve cap is convenient to disassemble and maintain.

Four cylindrical grooves are formed in the upper end face of the valve seat around the valve rod, and cylindrical pins capable of sliding relative to the cylindrical grooves are arranged in the cylindrical grooves. The lower end face of the valve cap is also provided with a positioning hole corresponding to the cylindrical groove, and magnetic steel is fixed in the positioning hole. The upper end of the valve cap can be also detachably fixed with a hand wheel which can enable the cylindrical pin to always keep leaning against the bottom of the cylindrical groove. When the hand wheel is not fixed on the valve cap, the cylindrical pin and the magnetic steel attract each other, then the upper end of the cylindrical pin can stretch into the positioning hole, and the lower end of the cylindrical pin is located in the cylindrical groove, so that the circumferential rotation of the valve cap is limited, and the effect of limiting the rotation of the valve rod is achieved to lock the valve rod. When the hand wheel is connected, the hand wheel can eliminate the magnetic force of the magnetic steel and act on a reverse magnetic field to give a force to the cylindrical pin to move towards the bottom of the cylindrical groove, so that the cylindrical pin is completely positioned in the cylindrical groove, the limit of the valve cap is relieved, and the valve rod is rotated to realize opening and closing.

The strong magnetic area can eliminate the magnetic force of the magnetic steel and simultaneously give a reverse magnetic field to enable the cylindrical pin to abut against the bottom of the cylindrical groove.

In the magnetic locking gate valve, a spring capable of keeping the cylindrical pin moving towards the positioning hole is further arranged between the cylindrical pin and the cylindrical groove.

When the strong magnetic area of the hand wheel is removed and disappears, the spring can give the cylindrical pin a force moving towards the direction of the positioning hole, so that the cylindrical pin is more easily attracted by the magnetic steel and the upper end of the cylindrical pin extends into the positioning hole.

In the magnetic locking gate valve, the valve body is internally provided with a positioning groove which cuts off the water passing channel along the radial direction, the positioning groove is internally provided with a truncated cone-shaped valve core, the left end surface and the right end surface of the valve core are respectively abutted against the groove walls on the two sides of the positioning groove to cut off the water passing channel, the valve core is provided with a mounting hole penetrating through the peripheral surface of the valve core, and the lower end of the valve rod extends into the mounting hole and is in circumferential.
