Abstract
The utility model relates to a high-temperature high-pressure temperature-pressure-reducing valve comprising a valve body, a valve seat, a valve clack, a valve rod, a valve cover, a water injector, an executive device, a sealing element and an installation part, wherein a valve body cavity at the outlet side of the valve seat is internally provided with a cage-type draft tube; and the valve clack is provided with a balance hole which communicates the cavity at the upper side of the valve clack and the valve body cavity at the lower side of the valve clack. The key point of the valve is that a sealing ring is arranged between the valve clack and a guide sleeve, thus increasing the sealing reliability between the valve clack and the guide sleeve, improving the valve sealing property, and being especially applicable to the temperature-pressure-reducing device on a high-temperature high-pressure steam system.
Description
Technical field
The utility model relates to a kind of decrease temperature and pressure device of vapour system, specifically about a kind of steam converter valve of high temperature and high pressure steam.
Background technique
Steam converter valve is the device that the high temperature and high pressure steam medium is converted to lower, low piezodielectric, mainly constitute by valve body, valve seat, flap, valve rod, valve gap, water spray projector system, actuating device etc., be provided with the cage guide shell in the valve body chamber of valve seat outlet side, flap is provided with equalizing orifice, this equalizing orifice is communicated with the cavity of flap upside and the valve body chamber of flap downside, pressure with both sides about the balance flap reduces valve operation power.Its major defect is: by flap excircle and guide sleeve inner circumference fitted seal, after in use wearing and tearing between the two, leak easily between the cavity of flap upside and the valve body import, sealability is unreliable.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides a kind of sealability reliable High Temperature High Pressure steam converter valve.
The technological scheme that realizes the utility model purpose comprises valve body, valve seat, flap, valve rod, valve gap, water spray projector system, actuating device, Sealing and assembling set, be provided with the cage guide shell in the valve body chamber of valve seat outlet side, flap is provided with equalizing orifice, this equalizing orifice is communicated with the cavity of flap upside and the valve body chamber of flap downside, mainly is between flap and guide sleeve seal ring to be set.
The utility model beneficial effect compared with prior art is to be provided with seal ring between flap and guide sleeve, increases the sealing reliability between flap and the guide sleeve, improves the valve seal performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now further describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments.
High Temperature High Pressure steam converter valve as shown in Figure 1, structure comprises valve body 1, valve seat 4, flap 6, valve rod 7, valve gap 11, water spray projector system, actuating device, Sealing and assembling set, be provided with cage guide shell 3 in the valve body chamber of valve seat 4 outlet sides, improve the stationarity of media flow, reduce vibration and noise.Flap 6 is provided with equalizing orifice 5, and this equalizing orifice 5 is communicated with the cavity of flap 6 upsides and the valve body chamber of flap 6 downsides, makes pressure balance on the flap 6, reduces valve operation power.Flap 6 bottoms are the cage throttling element, and in the centre cage guide shell are set, and this cage guide shell is enclosed within the top of water spray projector system water pipe 2, accelerate the atomizing of current.Between flap 6 and guide sleeve 10 seal ring 8 is set, sealing circle 8 is fitted on the flap 6 by gland 9.
