Abstract

The utility model discloses a tap, which comprises a handle, a valve cover, a valve rod, a valve seat, and a valve body. A membrane valve part which is made of rubber and can isolate a flow passage of the valve body from an inner cavity of the valve cover is arranged between the combined end faces of the valve cover and the valve body; the membrane valve part can also be a closing element, the membrane valve part can be compressed and clung with the sealing surface on the valve seat by the control of the valve rod, and the tap can be closed. The utility model has the advantages that the structure is novel and compact, the sealing performance is good, sealing does not need between the valve rod and the valve cover, and the external leakage of medium does not exist can be used for conveying water or other liquid in the industry.

Description

A kind of tap

The utility model is the tap that terminal is used on a kind of fluid circuit.

Existing tap is to utilize handle to drive valve rod as water tap, the folding on valve seat of control closure member opens and closes the break-make that realizes stream, the tap inner flow passage is full of whole inner chamber, because valve rod is in valve gap screws in tap, guarantee that both have the sealing under the relative movement situation, need to adopt the movable sealing structure form,, and seal unreliable easy leakage as employing stuffing box packing apparatus structure complexity.Closure member and valve seat adopt the scratch easy to wear of plane sealing form sealing surface usually in addition.

The utility model purpose is that the leading inner flow passage of a kind of energy partition of design is communicated with the valve gap inner chamber, thereby the valve rod valve cover chamber need not made the novel tap of Seal Design.

The utility model is following realization, is equipped with between the valve body valve gap connects in valve body and can produces deflection, elastically-deformable barrier film valve member.It separates leading inner flow passage and valve gap inner chamber, simultaneously again can be with sealing disjunction in chamber before and after the valve body inner flow passage as closure member.Drive valve rod by rotatable handle and control above-mentioned barrier film valve member and separate with sealing surface on the valve seat or compress applying, make leading open and close.The bending elasticity deformation of barrier film valve member can adopt ductility and flexible material and corresponding structure design to realize.

Accompanying drawing has provided the brief configuration of the utility model tap.

This novel tap contains following chief component: handle 1, valve gap 2, valve rod 3, barrier film valve member 4, valve seat 5, valve body 6, valve gap and valve body adopt scyewed joint, the barrier film valve member be contained in they in conjunction with between end face, the barrier film valve member is made of rubber material, has the V-shaped section shape, the central cone top die is pressed into pad 7, valve rod roof pressure on pad, make valve member with the vertex of a cone with the pressing of the valve base sealing conical surface or separate.

The utility model tap structure is compact novel, tap inner flow passage and valve gap inner chamber cut off, the valve rod valve cover chamber need not have fluid as Seal Design and leaks, when valve member and valve base chamber adopt as embodiment's conical surface seal, there is sealing surface to be difficult for scratch than plane sealing and weares and teares better tightness, the effect that prolong working life, operate nimblely again, make easy to maintenancely, can be widely used in industry or civilian transporting water and other liquid.

Claims

1, a kind of tap contains handle (1), valve gap (2), valve rod (3), valve seat (5), valve body (6), it is characterized in that valve gap, valve body connect in conjunction with end face between be equipped with by producing deflection, elastically-deformable barrier film valve member (4), this barrier film valve member can be formed by the valve rod control and the sealing surface of valve seat (5) to separate or unlatching, the closed state of pressing.

2, by the described tap of claim 1, it is characterized in that barrier film valve member (4) by the rubber making, has the V-arrangement section configuration, the top, center is molded into pad (7) valve rod roof pressure pad (7), and valve member is fitted with the sealing cone on cone top part and the valve seat.
