Description

Double connecting cold and hot water temp. regulator

A kind of duplex hot water or cold water's thermoregulator relates to a kind of indoor water-supply temperature adjustment control gear.

Existing duplex hot water or cold water's thermoregulator is to be regulated hot water or cold water's flow and met in the metallic water pipe by the cold water control valve on the hot and cold water pipe, hot water control valve, chews through overflow water then to flow in the basin.Manual flange plate on the control valve is brass or stainless steel, or metal-plated is coated with goods, and the color harmony structure is single, and brass and stainless steel consumption are big, and plating is coated with expensive, the cost height, and coating easily peels off, and do not fitted into modern decoration level.When particularly control valve is closed, often, reduction of service life, increase maintenance load because manual flange plate overtorquing causes the rubber seal piece on the valve core often to surpass limit of elasticity and cause fatigue damage.

Task of the present utility model is to provide a kind of melts that precious metal consumptions such as ceramic shell is in one, profile and damp look attractive in appearance, brass are few, hot water or cold water's thermoregulator of good airproof performance, long service life.

Task of the present utility model is achieved like this: make a housing with pottery, hot water or cold water's valve is packed into wherein, after the mixing chamber of hot water or cold water in housing mixes again the ceramic water on housing chew outflow.In addition, the valve seat of hot water or cold water's tube valve is processed into the concentric boss of a hollow, descending stroke when closing in order to the restriction valve core, promptly spacing, like this, just guaranteed that the rubber seal piece on the valve core carries out work in elastic limit, thereby prolong its working life, because being embedded in the cylinder of valve core body ［ 9 ］, rubber seal piece ［ 11 ］ is transition fit, when the rubber seal piece is pressed in valve seat ［ 12 ］ upward to limit of elasticity, sealing block will form an envelope limit in the end face excircle part of valve seat boss, so more guarantees good sealing property.

Major advantage of the present utility model is, whole hot water or cold water's thermoregulator melts ceramic package in one, and damp look elegant in appearance, and brass stainless steel consumption is few, good airproof performance, the long service life of rubber seal piece.

Concrete structure of the present utility model is shown in the following drawings:

Fig. 1 is hot water or cold water's thermoregulator overall structure figure.

Fig. 2 is hot water or cold water's thermoregulator housing figure.

Fig. 3 is the enlarging section component among Fig. 1.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

As shown in the figure, hot water or cold water's thermoregulator is made of housing ［ 1 ］ and hot water or cold water's valve ［ 16 ］ two-part.As shown in Figure 2, the thermoregulator housing is made an integral body with pottery, respectively there is a round tube hole at two ends, inner chamber has hot water or cold water's mixing chamber A, the channel C of its both sides communicates with the circular hole at two ends, and the passage D that makes progress is warm water and chews ［ 15 ］, the housing appearance of thermoregulator, can be processed into various needed colors according to different requirements, spilling water is chewed and can be made different profiles.As shown in Figure 1, the hot water or cold water's control valve in the hot and cold water thermoregulator, the extension lever on it ［ 2 ］, lifting screw ［ 3 ］, gland ［ 4 ］, filler ［ 5 ］, nut ［ 6 ］ and structural principle are known.The manual flange plate of pottery ［ 17 ］ also can be processed into various profiles, and two symmetrical radial grooves in the endoporus cooperate with extension lever ［ 2 ］.Nut ［ 6 ］ and connecting sleeve ［ 8 ］ are with being threaded, offer a through hole B on the cylndrical surface of connecting sleeve ［ 8 ］, must link up with the channel C of hot water or cold water's mixing chamber side in the thermoregulator housing inner chamber during assembling, the middle part that connects trepanning is a unthreaded hole, constitute Spielpassung with valve core body ［ 9 ］, add sealing gasket ［ 7 ］ between nut ［ 6 ］ and thermoregulator housing.As shown in Figure 3, the valve core of hot water or cold water's control valve is made up of valve core body ［ 9 ］, rubber seal piece ［ 11 ］ and screw ［ 10 ］, and wherein screw and rubber seal piece are known.Valve core body ［ 9 ］ is made with copper or engineering plastics, monnolithic case is as the circular enclosure of a band handle, the structural principle that handle and lifting screw ［ 3 ］ cooperate and known the same, inclusion cavity on the valve core body or circular enclosure, be a cylinder in fact, the rubber seal piece is gone in the cylinder hole with regard to setting-in and is become transition fit, is screwed at the bottom of the cylinder.The degree of depth of cylinder hole can equal the thickness H of rubber seal piece, also can be greater than H, this with the concentric boss two planar annular P of valve seat ［ 12 ］ hollow, M between distance dependent.Valve seat ［ 12 ］ is one section male-pipe, its end relative with valve core is processed into a concentric boss of hollow, the top is a smooth ring plain P, the valve seat planes that engages with rubber seal piece ［ 11 ］ when being valve closing, the step surface M of boss is the contact plane with valve core body cylinder end face N, be used for limiting valve core and close stroke in the process, boss two planar annular P, distance between the M, as previously mentioned, relevant mutually with the degree of depth of valve core body cylinder, promptly, if tube is dark when equating with rubber seal piece thickness, two planar annular P then, distance between the M is the 5-10% of close thickness of rubber, and is dark in the rubber seal piece as tube, then adds the 5-10% of rubber seal piece thickness for tube dark and difference rubber seal piece thickness.This value of the 5-10% of so-called rubber seal piece thickness is that the rubber seal piece is compressed subtracts the amount that falls during to limit of elasticity Value, that is rigidly connect when touching to valve seat planes P when the rubber seal piece
