Abstract

The utility model relates to a plane sealing valve which is composed of a valve body, a sealing gasket, a pin, a valve core assembly, a thrust bearing, a retainer, a pressing screw plug, a fastening screw plug, a valve rod, a hand wheel, etc. The valve core assembly is composed of a fixed body and a rolling body and the contact surface between the fixed body and the rolling body is a smooth plane surface. The fixed body is provided with a fluid flow inlet and a fluid flow outlet. The rolling body is provided with corresponding fluid flow passages. A relative position of the fixed body and the valve body is fixed by the pin. The pressing screw plug presses the retainer, the thrust bearing, the valve core assembly and the sealing gasket on the valve body tightly and is fastened and released by the fastening screw plug. The fixed body and the valve body are sealed by the seal gasket. The valve core assembly is sealed by a smooth plane surface. The utility model has the advantages of good sealing performance and convenient operation.

Description

The plane sealing valve

The utility model relates to valve, particularly is a kind of plane sealing valve.

The kind of valve is a lot, and gate valve, stop valve, ball valve etc. all are widely used, but at present at all kinds of valves of usefulness, all has problems such as sealing is poor, reliability is low, operation inconvenience.

The purpose of this utility model just is to provide a kind of plane sealing valve, to overcome at present in the deficiency with valve.

Above-mentioned purpose of the present utility model is realized by following technical proposals:

This valve by valve body, sealing gasket, pin, mangetic core assembly, thrust-bearing, retainer, compress screw plug, fastening screw plug, valve rod, handwheel etc. and form.Mangetic core assembly is made of fixed body and rotor, and both surface of contact are smooth flat, seal, fluid inlet and outlet are arranged on the fixed body, corresponding fluid passage is arranged on the rotor,, realize the circulation of fluid and close by the variation of rotor and fixed body relative position.Fixed body is determined relative position with valve body by pin in the mangetic core assembly, compressing screw plug is pressed on retainer, thrust-bearing, mangetic core assembly, sealing gasket on the valve body, and it is fastening locking by fastening screw plug, like this, fixed body and valve body are sealed by sealing gasket, and mangetic core assembly is then realized the smooth flat sealing.

Accompanying drawing is an overall structure schematic representation of the present utility model.

In conjunction with the accompanying drawings embodiment is described below:

In the accompanying drawing, the 1st, valve body, the 2nd, pad, the 3rd, fixed body, the 4th, rotor, the 5th, thrust-bearing, the 6th, retainer, the 7th, compress screw plug, the 8th, fastening screw plug, the 9th, protecting cover, the 10th, valve rod, the 11st, handwheel, the 12nd, nut, the 13rd, spring washer, the 14th, plain washer, the 15th, pin, A are pollutant exhaust holes.

In this valve, pollutant exhaust hole A is arranged on the valve body 1, in order to discharge inner dirt, fixed body 3 constitutes mangetic core assembly with rotor 4.Different according to use occasion and circulation medium, fixed body, rotor can adopt different materials in the mangetic core assembly, also can apply special material at its contact surface, to improve its corrosion-proof wear.

In the use, drive valve rods 10 by handwheel 11 rotor 4 is turned over certain angle, the passage on the rotor 4 is communicated with import and export on the fixed body 3: on the contrary both sealings of staggering can realize the switching of valve.

Because in this structure, the switching of valve only need turn over certain angle, has adopted thrust-bearing 5 so rapid operation, convenient, fast in the hold-down mechanism in addition.
