Abstract
The utility model belongs to the technical field of stop valves and in particular relates to a novel integrated stop valve. The novel integrated stop valve comprises a valve rod, a valve clack, a valve body, a hand wheel component, a bearing device and a valve rod rotation prevention device, wherein the valve clack and a valve seat part of the valve body are sealed; one end of the valve rod is connected with the valve clack, and the other end of the valve rod penetrates through the bearing device to be connected with the hand wheel component; and the valve body and the valve rod are connected and positioned through the valve rod rotation prevention device. The valve body, the valve clack and the valve rod are made of type 316 stainless steel, and the strength and hardness of the valve are guaranteed. The traditional valve rod rotation prevention device is improved, the integrated dissociation of the valve rod is realized, the machining process is simplified, and the production cost is greatly reduced; and meanwhile, due to the additional arrangement of the bearing device, the operating stability of a product is improved, and the torque force required in the process of opening and closing the valve is greatly reduced.
Description
Technical field
The utility model belongs to stop valve manufacturing technology field, particularly relates to integral cut-off valve.
Background technique
Stop valve is to utilize the valve rod lifting to drive flap, thereby the distance that changes between flap and the valve seat reaches the valve that switch is controlled.It is little that stop valve has working stroke, good airproof performance, and wear resistance is good, the advantages such as long service life.Especially integral cut-off valve, because it is simple in structure, reliable and be widely used in the industries such as machinery, chemical industry, oil.
The motion mode of integral cut-off valve valve rod is divided into lifting rotation rod-type (being that handwheel is with the valve rod rotation and lifting) and elevating lever-type (being the valve rod lifting, not lifting of handwheel).In adopting elevating lever-type stop valve, flap is only done straight line motion, effectively reduces the friction between flap and valve body in the switching process.But in traditional elevating lever-type stop valve, anti-valve rod slewing gear complicated structure, processing technology is had relatively high expectations, and is not easy to inspection and maintenance.Simultaneously, the larger torsion of needs when complicated structure causes the stop valve switch, feel is relatively poor.
The model utility content
The utility model provides a kind of simple in structure, easy to operate and novel integrated stop valve that cost of production is lower for solving the problems of the technologies described above.
For achieving the above object, technical solution adopted in the utility model is as follows:
Described novel integrated stop valve comprises: valve body, flap, valve rod, hand wheel component, bearing means, anti-valve rod slewing gear.The valve seat part of described flap and described valve body seals, and described valve rod one end is connected with described flap, and the other end passes described bearing means and is connected with described hand wheel component, and described valve body is connected the location with described valve rod by described anti-valve rod slewing gear.
Described anti-valve rod slewing gear comprises: pressing plate, gland, flat key, Packing seat, full tooth double-screw bolt, hexagon nut.Gland needs to be divided into two along gland endoporus symmetry axis equalization before installing with rectangle ear shape structure, so that install.Pressing plate is convenient to gland installation and location with ear shape groove.The gland endoporus is connected by flat key with valve rod, prevents that effectively valve rod from rotating, and the gland end is connected the location with Packing seat, and gland is connected by ear shape structure with pressing plate, and pressing plate is connected with hexagon nut by full tooth double-screw bolt with stop valve body.
Described hand wheel component comprises: handwheel, dust cover, thrust-bearing, hole back-up ring, Stem Mut, handwheel flat key, shaft block ring.Stem Mut is connected by thrust-bearing with valve body, and Stem Mut one end is connected by flat key with handwheel, and this end arranges the hole back-up ring simultaneously, dust cover, and shaft block ring prevents that dust from entering valve rod, affects the stop valve service behaviour.
Described bearing means comprises: bearing nut, needle bearing, plate, interior hexagonal circle thread screw.Bearing nut is connected by screw thread with valve body, and the built-in needle bearing of bearing nut is connected by interior hexagonal circle thread screw with plate.
The beneficial effects of the utility model are:
(1) takes above-mentioned design, improved traditional anti-valve rod slewing gear, simplified processing technology, significantly reduce production costs.
The integral type that (2) can realize valve rod in repair and maintenance detaches, and maintains easily personnel's maintenance.
(3) improve traditional somewhat complex design, simplified product structure, beautified product appearance.
(4) add bearing means, strengthen the stability of product operation, required torsion when greatly reducing switch valve has improved the feel of operation.

Embodiment
Valve body 1 is connected to form hard sealing surface with flap 2, and flap 2 the other ends are connected with valve rod 3 by T-slot, and valve rod 3 is provided with keyway.Packing seat 17 and stuffing box packing 18 location and installation are on valve body 1.Be installed in the gland 16 of Packing seat 17 tops, with rectangle ear shape structure, need to be divided into two along gland endoporus symmetry axis equalization before installing, so that install.Gland 16 endoporus are connected by flat key 6 with valve rod 3, prevent that effectively valve rod from rotating.Pressing plate 7 is convenient to gland 16 and is installed and the location with ear shape groove.Pressing plate 7 and valve body 1 are connected with hexagon nut by full tooth double-screw bolt 5 and are connected.Valve rod 3 the other ends and Stem Mut 9 are threaded connection, and Stem Mut 9 the other ends are connected by handwheel flat key 11 with handwheel 12.Bearing nut 10 is connected with needle bearing 15, and is threaded connection with valve body 1.
The utility model further is set to: valve body 1, the material of flap 2 and valve rod 3 is 316 stainless steels, guarantees intensity and the hardness of valve.Screw thread on valve rod 3 and the Stem Mut 9 is left-handed thread.Working procedure is as follows: handwheel 12 rotates, and drives Stem Mut 9 rotations, and Stem Mut 9 band ovable valve stems 3 are done straight line motion, and valve rod 3 drives flap 2 and does straight line motion, finishes the opening and closing of sealing surface.
