Abstract

The utility model discloses a household maintenance-free double temperature faucet. A valve seat sealing pair assembly consists of four parts, namely a ceramic valve seat, a ceramic rotor, a spring and a valve rod. According to the utility model, the connection dimension of the conventional household double temperature faucet is not changed, seven parts in the valve element assembly in the prior art are omitted, only four parts of which the shapes and the structures are simple are adopted to adjust the water temperature and the flux, the rotation can be arbitrary and unfixed, and the action of poking the valve rod can be reduced; under the condition of keeping water supply, the valve rod can be pulled out to rotate a valve cover so as to adjust the spring pressure, namely the specific pressure of valve seat sealing pairs; the function of automatic compensation of loss of the valve seat sealing pairs is achieved, no part needs to be repaired and replaced, and the advantage of achieving the maintenance-free effect by a simple method is achieved.

Description

The two temperature taps of freedom from repairs

Technical field

The utility model relates to the two temperature taps of a kind of family expenses freedom from repairs, its valve base sealing vice president becomes to be made up of porcelain valve seat, porcelain rotor, spring, four parts of valve rod, there is the automatic compensation function of the secondary wear extent of valve base sealing, each part shape and simple in structure, can any direction rotation regulate water temperature and flow, without location, there is no plastic part, do not need repairing and change accessory, belonging to design and the manufacturing technology field of Household water tap.

Background technique

The two temperature taps of family expenses of prior art, its valve base sealing vice president become by valve rod, rotating shaft, rotation chute pipe, slip sheet cover, porcelain slide plate, porcelain valve seat, assembly box, lid, three cushion rubbers totally 11 parts form, wherein having 8 parts is plastic article, complex geometry mostly, manufactures and installation precision is had relatively high expectations, the specific pressure of valve base sealing pair is pressed on assembly box on the base plate in valve casing and obtains by the valve gap of water tap, valve rod stir and rotate slide plate repeatedly after, slide block on slip sheet cover, rotate the chute on chute pipe, stem head and rotary shaft hole all can wear and tear and occur room, because not possessing the automatic compensation function of wearing and tearing, the specific pressure of valve base sealing pair reduces, there is water clock, that location piece in assembly box is less again, firmly fragile slightly greatly, causing water outlet to diminish maybe can not use, the core hole dimension of each producer shell is variant, be difficult to general, replacing accessory can not repaired by general family, discarded unnecessary waste and the dismounting difficulty of causing of entirety, therefore be necessary existing The technology to improve.

Summary of the invention

The purpose of this utility model is to overcome the two temperature taps of family expenses of prior art, the part of Spool assembly is more, shape and structure is more complicated fragile, there is no the problem of auto-compensation wearing and tearing function, novel a kind of freedom from repairs pair temperature taps that provide, Spool assembly is by porcelain valve seat, porcelain rotor, spring, the very simple part composition of four geometrical shapies of valve rod, reduce by seven parts than prior art, and there is the automatic compensation function of the secondary wear extent of valve base sealing, the specific pressure of sealing pair is constantly provided by spring, and can be under spool opening state, pull-out valve rod, adjust the specific pressure of spool, reach the object of freedom from repairs, solve the problem that the two temperature taps of prior art family expenses need repairing.

The utility model completes by following technical proposal: the two temperature taps of a kind of freedom from repairs, formed by the porcelain valve seat in valve casing and valve gap, porcelain rotor, spring and valve rod, and porcelain valve seat and porcelain rotor are sealing pair; It is characterized in that there are three through holes on described porcelain valve seat, center hole is water outlet, another two holes are hot and cold water inlet hole, the sealing surface end of described porcelain rotor is provided with the dark groove of U-shaped half, align with the center hole of porcelain valve seat in the semicircle middle part of groove, two straight section top outer of U-shaped groove are respectively stretched out an elongated circular groove, and its upper end is communicated with U-shaped groove, and lower end reaches respectively the side of the cold and hot water inlet of porcelain valve seat; The axial the other end of porcelain rotor middle part is provided with square hole pipe; The square toes of described valve rod one end insert in the square hole pipe of porcelain rotor, and the other end and handle are connected as a single entity; Described spring housing, on the square hole pipe of porcelain rotor and the cylindrical of valve rod, is pushed down porcelain rotor by valve gap by spring and is adjacent on porcelain valve seat.

Working procedure of the present utility model: porcelain valve seat is fixed on the base plate in valve casing, three through hole positions are identical with the paddle hole position of valve casing, and center hole is osculum, and 7 positions are cold water inlet hole, and 5 positions are hot water inlet hole; Porcelain rotor is by spring compression on porcelain valve seat, and the perpendicular bisector of the U-shaped groove of porcelain rotor sealing surface end during just to 12 positions, is novel closed condition, aligns at any time with the center hole of porcelain valve seat in the semicircle middle part of groove; While porcelain rotor being turned left to 7 positions by valve rod, it is cold water standard-sized sheet, it while being rotated further 5 positions, is cold and hot mixing water standard-sized sheet, water temperature regulates and uninterrupted, area of contact by U-shaped groove and two elongated circular grooves and cold and hot water inlet determines, the perpendicular bisector that turns again porcelain rotor upper groove is got back to positive 12 positions, closes cold and hot water inlet simultaneously; Turn right U-shaped groove to 5 position of porcelain rotor is hot water standard-sized sheet, uninterrupted and water temperature regulate with turn left identical.

Novel sealing pair wear extent automatic compensation function and the working principle of freedom from repairs: the sealing pair being formed by porcelain valve seat and porcelain rotor, its specific pressure is constantly provided by spring, sealing pair weares and teares a bit, spring automatic impaction a bit, remain the state of being adjacent to, make it have the function of auto-compensation wear extent, the pressure of spring also can regulate by screwing valve gap; Valve rod is inserted in the square hole pipe of porcelain rotor, drives porcelain rotor to rotate not wearing and tearing, there is no other plastic cement part in valve casing; Stainless steel spring only produces static pressure, does not have fore and aft motion not fragile; The porcelain sealing pair durable wear of high hardness, the automatic compensation function of the secondary wear extent of novel existing valve base sealing, does not need again to repair the part of changing, and therefore can be described as the two temperature taps of freedom from repairs water.The utility model compared with prior art has following advantages and effect: adopt such scheme, the utility model does not change the Conncetion cimension of the two temperature taps of existing family expenses, reduce seven parts in prior art Spool assembly, only with four shapes and all simple part adjusting water temperature and flows of structure, rotate arbitrarily delocalization, reduce the action of stirring valve rod; Article two, elongated circular groove has the water saving effect of the fixing little water yield; In the situation that not cutting off the water, can pull out both specific pressures of valve base sealing pair of valve rod rotary valve cover Regulation spring pressure; Have the automatic compensation function of the secondary wear extent of valve base sealing, do not need to repair and change any Component, it is also advantageous in that the effect that just can reach freedom from repairs by simple method.
