Abstract
The utility model discloses a kind of gate valve of detachable valve seat, belong to valve field.The gate valve of this detachable valve seat comprises valve rod, valve seat, flashboard, and valve body is divided into one-level valve body and secondary valve body, and flashboard is arranged in one-level valve body; Described valve seat is embedded in seat ring, and valve seat and flashboard both sides all seal laminating; Described seat ring is arranged in one-level valve body fluid passage, and seat ring and one-level valve body joint are provided with seal ring; Described secondary valve body is threaded with one-level valve body, and one end puts in one-level valve body and props up seat ring.Adopt the utility model to achieve the convertibility of valve seat, do not need gate valve entirety to scrap, save financial cost.
Description
Technical field
The utility model relates to valve field, specifically a kind of gate valve of detachable valve seat.
Background technique
Gate valve makes open-shut device with flashboard and move along valve seat axes normal direction, to realize the valve of switching motion.Gate valve can only standard-sized sheet and complete shut-down, and open-shut device is flashboard, moving direction and flow direction perpendicular, square I-shaped gate valve two sealing surfaces form wedge shapes, key groove is different with valve parameter.
In the prior art, the valve seat of most gate valve processes through butt welding processing in the chamber of valve body, do not have special instrument to be very difficult to take out, and once there is poorly sealed defect, many users only have replacing gate valve, then scrap with the gate valve changed.The economic loss caused is large, cost of idleness.
Model utility content
The utility model provides a kind of gate valve of detachable valve seat, is intended to the dismounting and change realizing valve seat, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A gate valve for detachable valve seat, comprises valve rod, valve seat, flashboard, it is characterized in that: valve body is divided into one-level valve body and secondary valve body, and flashboard is arranged in one-level valve body; Described valve seat is embedded in seat ring, and valve seat and flashboard both sides all seal laminating; Described seat ring is arranged in one-level valve body fluid passage, and seat ring and one-level valve body joint are provided with seal ring; Described secondary valve body is threaded with one-level valve body, and one end puts in one-level valve body and props up seat ring.
Further, described secondary valve body and one-level valve body joint are provided with the protective metal shell of banding.
Further, described secondary valve body and the one-level valve body connecting thread end are also provided with seal ring near one-level valve body port.
Further, described seal ring is the sealing O shape circle of nitrile rubber material.
The beneficial effects of the utility model are: valve body is divided into one-level valve body and secondary valve body, and connects with screw thread, achieve the detachability of valve body, split type valve body is also more easily produced.Use the joint of protective metal shell banding one-level valve body and secondary valve body again, make its structure more stable.Be embedded in by valve seat in seat ring, seat ring is arranged in one-level valve body, and when dismounting valve seat changed by needs, secondary valve body of only need dismantling, takes out seat ring and can change in one-level valve body, simple to operate, easily realizes.
Accompanying drawing explanation
Fig. 1 is the gate valve structure schematic diagram of the detachable valve seat that the utility model provides.
Mark in figure: 1 be secondary valve body, 2 be one-level valve body, 3 be protective metal shell, 4 be seat ring, 5 be valve seat, 6 be flashboard, 7 be valve rod, 8 be sealing O shape circle.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of gate valve of detachable valve seat, comprises valve rod 7, valve seat 5, flashboard 6, and valve body is divided into one-level valve body 2 and secondary valve body 1, and flashboard 6 is arranged in one-level valve body 1; Described valve seat 2 is embedded in seat ring 4, and valve seat 2 and flashboard 6 both sides all seal laminating; Described seat ring 4 is arranged in one-level valve body 2 fluid passage, and seat ring 4 and one-level valve body 2 joint are provided with seal ring 8; Described secondary valve body 1 is threaded with one-level valve body 2, and one end puts in one-level valve body 2 and props up seat ring 4, secondary valve body 2 and one-level valve body 1 joint protective metal shell 3 banding.Described secondary valve body 2 is also provided with seal ring 8 with the one-level valve body 1 connecting thread end near one-level valve body 2 port, and seal ring 8 is the sealing O shape circle of nitrile rubber material.
When needs are dismantled, first unclamp for the protective metal shell 3 of banding one-level valve body 2 with secondary valve body 1 joint.Outwards twist screw thread again, make secondary valve body 1 not hold out against seat ring 4, seal failure between valve seat 5 and flashboard 6.Dismantle after secondary valve body 1, smear the fluid passage of one-level valve body 2 with lubricant grease, then seat ring 4 is carried out with changing from the taking-up of one-level valve body 2 fluid passage.Adopt the utility model structure simple, easily realize, only need change valve seat, no longer need that entirety is carried out to gate valve and scrap, save financial cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
