Description

A kind of improved enclosed ball-cock assembly

Technical field

This utility model relates to valve technology field, particularly relates to a kind of improved enclosed ball-cock assembly.

Background technology

People, in life and producing, are required for reservoir, including attemperater, the central heating of solar water heater The water tank of system, the water tower of industrial and mining establishment, fire cistern and boiler replenishing water case etc., application ball-cock assembly is mended in such devices Water can be saved artificial and prevent water resource waste.Existing ball-cock assembly is to be separated with ball float by valve, outside valve Crank arm and ball float is to control valve, exist and install and use the shortcomings such as inconvenience, easy to failure, service life is short, and valve plate or valve Core is to carry out closing in face of current or the hydraulic pressure direction of tap water, beating of the pressure action direction of tap water and valve plate or spool Evolution, to identical, easily causes the close shortcoming easily leaked that is not closed completely.

" the built-in ball float that open Chinese Patent Application No.: the CN201310319114.8 of current existing technology provides Valve ", particular content is: be mainly made up of valve body, main valve plate, pressure releasing valve core, ball float and valve casing, wherein, have in valve body uuper valve chamber, Lower valve chamber, center slideway and sealing surface a, center slideway, at the center of the top wall body of uuper valve chamber, main valve plate has circular through holes, The circular through holes of main valve plate constitutes pressure release passage, and the center of pressure releasing valve core upper end has connecting rod to pick out, and one end of valve body has and connects into water Mouthful, water inlet orifice is to lower valve chamber, and the other end of valve body has water outlet mouthpiece, water outlet mouthpiece to be communicated to uuper valve chamber；Valve casing connects In the upper end of valve body, the interior space of valve casing and valve body upper end constitutes hydroecium, and ball float is arranged in hydroecium, and there is aerofluxus on the top of valve casing Interface picks out, and the design of this structure can not only play closedown ball-cock assembly when water level puts in place, it may have from close effect, but it is close to leak outside Envelope uses single sealing, when bad seals or sealing surface occur that foreign body blocks, now seals and will lose effect, outside easily causing Leakage, causes often occurring that floods cause water source to waste in a large number, and its main valve plate uses up closedown without Design Orientation function, its main valve Below plate relatively big with the contact area of water, according to law of buoyancy, the most quickly that main valve plate top is the most stifled when hydraulic pressure is the biggest Live water stream channel, anhydrous in causing finding water tower during a large number of users urgent need water, not only have close according to above-mentioned built-in ball-cock assembly Envelope sex chromosome mosaicism, structure design is not the most quite reasonable, is now easily caused water according to market reaction said structure Shortcomings and overflows Pond, seals and easily blocks, and easily produces anhydrous phenomenon, easily causes water waste, causes economic loss, also can cause time serious The generation of floods, makes troubles to user, it is impossible to bring good economic benefit.

Summary of the invention

Therefore, for above-mentioned problem, the utility model proposes a kind of water lev el control accurate, simple in construction, there is filtration Function, ball float close seal without jam, service life is long, when ball float is inoperative do not result in yet water spilling pond modified model Closed ball-cock assembly.

For achieving the above object, this utility model have employed techniques below scheme: a kind of improved enclosed ball-cock assembly, main Valve body to be included, lower bonnet, valve rod and ball float, described valve body is provided with horizontal intake tunnel and exhalant canal, and described lower bonnet sets Below valve body, described valve body is positioned at intake tunnel and is provided with lower valve base at the friendship neighbour of exhalant canal, and described lower valve base is provided with The valve port being connected with intake tunnel and exhalant canal, described valve body exhalant canal is also arranged above upper valve base, described upper valve base Being additionally provided with outlet, described ball float is located at valve inner epicoele, and is connected with one end of valve rod, and the described valve rod other end passes Upper valve base and lower valve base, and be connected with seal receptacle, described valve rod is pinned by nut with seal receptacle, described lower valve base and sealing Being additionally provided with sealing gasket between Zuo, described drainage screen is located between lower valve base and lower bonnet, described location spring be located at upper valve base with Between seal receptacle, described protection cap is located at above valve body.

Improve further: be additionally provided with sealing gasket between described protection cap and valve body, between described protection cap and valve body Use threaded.

By use preceding solution, the beneficial effects of the utility model are: described drainage screen be located at lower valve base with under Between bonnet, use filter screen structure to be mainly designed to cross the foreign material in drainage, prevent the sealing gasket in seal receptacle different Thing blocks and loses sealing effectiveness, plays key effect in this is novel, and protection ball float is normally-open or closes, described location bullet Spring is located between upper valve base and seal receptacle, and Design Orientation spring its role is to water inlet to be kept unobstructed seal receptacle location, Preventing from not supplying water into being blocked by valve port seal receptacle moment during water, prevent unexpected anhydrous generation, this design is just right, very Rationally, solving all problems for user in use, described protection cap is located at above valve body, and its protection cap is in order to dust-proof, anti- Soil is fallen into, and can prevent again water from overflowing pond, it is to avoid to cause economic loss, it is ensured that supplies water normal, does not haves showing of floods As.

It is additionally provided with sealing gasket between described protection cap and valve body, uses between described protection cap and valve body and threaded, institute State valve body and be arranged over a venthole.
