Abstract

A novel ceramic chip valve mainly comprises a valve body, a handle, a mandrel combination, a lower ceramic chip and a lower sealing gasket. The novel ceramic chip valve has the advantages that the valve has simple and compact structural design; moreover, a mandrel is formed by components and parts through movable assembly, thereby ensuring reliable performance and eliminating the possibility that a valve core is separated from the valve body; a compression screw-thread cover is of a hollow cylinder shape, and does not have an end edge as compared with a screw-thread cover with an end edge in the prior art; moreover, the entire compression screw-thread cover can be screwed in the valve body, and is adhered to a platform at the lower end of the internal thread of a valve body cavity, thereby reducing occupied space; therefore, the volume of the valve can be relatively minimized under the condition of identical use effect so as to save materials and increase economic benefits.

Description

A kind of new ceramics sheet valve

Technical field

The utility model relates to valve, particularly a kind of new ceramics sheet valve.

Background technique

At present, the spool of used ceramic plate valve is to consist of an absolute construction by ceramics, mandrel, valve core case and seal ring on the market, and this valve core structure is comparatively complicated.Its limit stoper is located in the valve core case, does not contact directly with valve body, and when undue force, whole spool just may break away from valve body, causes valve to damage.

The model utility content

The purpose of this utility model is to overcome above-mentioned deficiency, disclose a kind of simple in structure, compact, mandrel to society and assembled by the component activity, reduced the possibility of spool disengaging valve body, under identical using effect situation, volume is less, can reach economical with materials, improve the new ceramics sheet valve of economic benefit.

This new ceramics sheet valve comprises valve body, handle, mandrel combination, following ceramic chip, lower seal rubber cushion.Described mandrel makes up by mandrel, collet threaded lid, last ceramic chip, upward seal rubber pad is formed.Unlike the prior art be: end face is being provided with more than one limiting stopper at the top in valve body chamber, its height greater than more than the 1mm, width greater than more than the 2mm, the thickness of limiting stopper is greater than more than the 1mm.The positive stop that intracavity of handle is provided with is corresponding with the position of the limiting stopper that the top end in valve body chamber is provided with, and the maximum rotating range that makes handle is 90 degree.The end face of lower end and water intake jointing place is being put the lower seal rubber cushion in the valve body chamber, have that ceramic chip clamps the top that fits over the lower seal rubber cushion under the circle of two fan shape holes, direct-axis on the mandrel to an end on be provided with step, last seal rubber pad and being on the successively supporting end face that is contained in this step of the collet threaded lid of hollow cylinder tubular, offer into the notch of semi-open-type in the bottom of step, the ceramic chip that is butterfly-shaped shape is installed in the bayonet socket of the end face that protrudes on the notch both sides.The mandrel combination vertical is fitted in the valve body chamber, and the collet threaded lid screws mandrel and valve body, and ceramic chip and following ceramic chip are fitted tightly, and does not have water clock when guaranteeing valve closes.The collet threaded lid is the hollow cylinder tubular, relatively it is no ora terminalis with prior art the ora terminalis threaded cap, upper end portion perpendicular to the valve body accent is provided with 3 limits with upper ejector lever screens or hole clipping groove, can whole precession valve body, reduced occupation space, reduced valve volume relatively.

The utility model ceramic valve mainly is made up of valve body, handle, mandrel combination (contain the collet threaded lid, go up seal rubber pad, go up ceramic chip and mandrel), following ceramic chip, lower seal rubber cushion.When Open valve turn handle, mandrel drives goes up the ceramic chip rotation, the step bottom that fan shape hole that current have by lower seal rubber cushion and following ceramic chip and mandrel are provided with is clamping the notch of butterfly-shaped shape ceramic chip, water outlet through valve body flows out, when valve opening arrived maximum, the positive stop of intracavity of handle was blocked by the limiting stopper that the valve body upper-end surface is provided with.When throttle down turn handle, the other end of the positive stop of intracavity of handle is blocked by the other end of the limiting stopper that the valve body upper-end surface is provided with, or another positive stop of intracavity of handle is blocked by another limiting stopper that valve body is provided with, because limiting stopper and valve body are one, reasonable in design, stopped the situation that spool breaks away from valve body.

Because the utility model ceramic valve mainly is by valve body, handle, the mandrel combination, following ceramic chip, it is simple in structure that the lower seal rubber cushion is formed, compact, mandrel is assembled by the component activity, reliable performance, stopped the possibility of spool disengaging valve body, its collet threaded lid is the hollow cylinder tubular, relatively it is no ora terminalis with prior art the ora terminalis threaded cap, can whole precession valve body, fit with the platform of internal thread lower end, valve body chamber, reduced occupation space, thereby can be under the situation of identical using effect, volume can be accomplished minimum relatively, save material, improved economic benefit.
