Abstract
The utility model discloses a gate valve with a valve rod rotating display function and gate plate opening and closing functions. The gate valve comprises a valve cover, a valve rod penetrates through the valve cover, the valve rod is provided with an external thread, a nut is screwed on the valve rod, an indicating sleeve is fixedly arranged on a valve seat, a pointer is arranged on a spiral ring, the indicating sleeve is provided with a vertical chute, and the pointer is arranged in the chute in a sliding mode. The gate valve is reasonable in structural design and easy to disassemble, assemble and maintain, can be installed at any position, and is simple and compact in structure, small in operating torque, quick in rotation and opening, linear in flow rate property and good in adjusting performance; and the position of the pointer moving vertically along the chute displays the rotating angle of the valve rod in real time.
Description
Technical field
The utility model relates to the gate valve field, specifically belongs to a kind of gate valve that shows the flashboard opening and closing that rotates with valve rod.
Background technique
At present, butterfly valve obtains using very widely in many fields such as oil, chemical industry, metallurgy, water power as a kind of parts that are used for realizing pipe-line system break-make and flow control.In known gate valve technology, its seal form adopts sealing configuration more, and sealing material is rubber, teflon etc.Because the restriction of structure characteristic, be not suitable with high temperature resistant, high pressure and corrosion-resistant, the industry such as resistance to wear, the rotation angle of valve rod can't show in real time simultaneously.
The model utility content
The purpose of this utility model provides a kind of the rotation with valve rod and shows valve opening and the gate valve of closing, reasonable in design, easily dismounting and maintenance, and can install at an arbitrary position, simple in structure, compact, the operation moment of torsion is little, and pointer shows the position of flashboard opening and closing in real time along the position that chute moves up and down.
The technical solution of the utility model is as follows:
A kind of gate valve that shows the flashboard opening and closing that rotates with valve rod, include valve seat, passed valve rod in the valve seat, on the valve rod with outside thread, be screwed with spiral ring on the valve rod, be fixed with indicating sleeve on the valve seat, on the spiral ring with pointer, have vertical chute on the indicating sleeve, pointer is slidingly mounted in the chute.
Described indication shroud places outside the valve rod.
Reasonable in design of the present utility model, easily dismounting and maintenance, and can install at an arbitrary position, simple in structure, compact, the operation moment of torsion is little, and 90 degree revolutions are opened rapidly, the Flow characteristics straight line that becomes, adjusting function is good, and pointer shows the valve rod rotation angle in real time along the position that chute moves up and down.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of gate valve that shows the flashboard opening and closing that rotates with valve rod, include valve seat 1, passed valve rod 2 in the valve seat 1, on the valve rod 2 with outside thread 3, be screwed with spiral ring 4 on the valve rod 2, be fixed with indicating sleeve 5 on the valve seat 1, with pointer 6, have vertical chute 7 on the indicating sleeve 5 on the spiral ring 4, pointer is slidingly mounted in the chute 7, and the indication shroud places outside the valve rod.
Claims (2)
1. gate valve that rotate to show the flashboard opening and closing with valve rod, include valve seat, it is characterized in that: passed valve rod in the valve seat, on the valve rod with outside thread, be screwed with spiral ring on the valve rod, be fixed with indicating sleeve on the valve seat, on the spiral ring with pointer, have vertical chute on the indicating sleeve, pointer is slidingly mounted in the chute.
2. a kind of gate valve that rotate to show the flashboard opening and closing with valve rod according to claim 1, it is characterized in that: described indication shroud places outside the valve rod.
