Abstract
The utility model relates to an integral abrasion-resistant metal sealing ball valve, which comprises a valve body, a valve seat, a ball, a valve stem, a sealing part and a mounting part, wherein the lower end of the valve stem is fixedly connected with the ball. The integral abrasion-resistant metal sealing ball valve is mainly characterized in that the valve body is made of abrasion-resistant materials by means of integral forging and forming, the diameter of an inlet channel of the valve body is larger than that of an outlet channel, a flow guide sleeve in a flared shape is arranged in the inlet channel of the valve body, a flared small end of the flow guide sleeve is connected with the valve seat on an inlet side of the valve body, and the diameter of the flared small end is equal to that of a flow channel of the valve seat and the ball. Washing of media to the valve seat can be decreased, the sealing performance of a sealing surface of the valve seat is protected, and the integral abrasion-resistant metal sealing ball valve has the advantages of washing resistance, abrasion resistance, fine sealing performance, long service life and the like, and is applicable to a drain valve of a high-pressure heater system in a power station.
Description
Technical field
The utility model relates to valve field, specifically about a kind of metal seal ball valve.The utility model is applicable to the high-pressure heater drain valve.
Background technique
The high-pressure heater drain valve is the critical component in the high-pressure heater system of power station, the valve inlet outlet pressure differential is big, its inlet pipeline bore is greater than the outlet conduit bore, the common metal seal ball-valve uses when the high-pressure heater system, the import medium washes away very big to valve seat, sealing surface of seat can be washed away very soon and lose sealing function.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides a kind of and anti-ly washes away, the integral type wear-resistant metal seal ball valve of wear-resistant, good seal performance, long service life.
The technical solution of the utility model comprises valve body, valve seat, spheroid, valve rod, Sealing and assembling set, fixedly connected with spheroid in the lower end of valve rod, mainly be that valve body adopts high-abrasive material solid forging moulding, valve body inlet passage diameter is greater than the outlet passage diameter, in the valve body inlet passage, establish a water conservancy diversion cover, this water conservancy diversion cover is the horn mouth shape, and its horn mouth small end is connected with the valve seat of valve body suction side, and the horn mouth end diameter equates with the Flow diameter of valve seat, spheroid.
In above technological scheme, the valve outlet channel outer wall has bottleneck formula structure.
The utility model has the advantages that at valve body and adopt high-abrasive material solid forging moulding; in its inlet passage, be provided with the water conservancy diversion cover of horn mouth shape; the big runner of valve body import is pursued excessively to the runner that equates with valve seat, spheroid; reduce medium to valve seat wash away; the sealability of protection sealing surface of seat, have anti-ly wash away, characteristics such as wear-resistant, good seal performance, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Integral type wear-resistant metal seal ball valve as shown in Figure 1, comprise valve body 1, valve seat 3, spheroid 2, valve rod 9, Sealing and assembling set, fixedly connected with spheroid 2 in the lower end of valve rod 9, the upper end of valve rod 9 is connected with driving mechanism 12, has the metallic sealing section that cooperatively interacts between valve seat 3 and the spheroid 2.Valve body 1 adopts high-abrasive material solid forging moulding, the inlet passage diameter of valve body 1 is greater than the outlet passage diameter, in the inlet passage of valve body 1, establish water conservancy diversion cover 5, this water conservancy diversion cover 5 is the horn mouth shape, its horn mouth small end is connected with the valve seat 3 of valve body 1 suction side, and the diameter of horn mouth small end equates with the Flow diameter of valve seat 3, spheroid 2.Between the valve seat 3 of water conservancy diversion cover 5 and suction side, be provided with butterfly spring 4, absorb the thermal expansion between valve seat 3 and the spheroid 2.
Have bottleneck formula structure at valve body 1 outlet passage outer wall, this bottleneck formula structure plays the effect of pipe stress by valve body 1 solid forging moulding.Be provided with separation sleeve 6 and stuffing box packing 7 between valve body 1 and the valve rod 9, stuffing box packing 7 is installed between valve body 1 and the valve rod 9 by Gland 8.Driving mechanism 12 is fixedly installed on the valve body 1 by heat radiation rack 11 and support 10.
