Description
Technical field
The utility model relates to pipeline valve and makes the field, especially relates to a kind of high leak tightness and takes over soon trap valve.
Background technique
In the pipelines such as the oil of tap water or industrial application, gas, water, metal tube is the higher and defective such as easily get rusty, easily be corroded due to its price, is eliminated gradually.And aluminium-plastic pipe and plastic tube have good physics characteristic, Economy, practicability and Security and make advanced piping compatibility be widely used in hot and cold water in industry, civil engineering, combustion gas, pressurized air, heating, food and industrial liquid pipeline system, become most popular a kind of tubing.Because pipeline valve generally can not directly be connected with these tubing by screw thread, need to valve be connected by a link not only troublesome poeration, and the poor sealing of a lot of links self with tubing, and the position sealing that link is connected with valve body is not high yet, easily leaks.
The model utility content
The utility model provides a kind of good airproof performance in order to overcome the deficiencies in the prior art, and is simple in structure, the trap valve of taking over soon easy to use.
To achieve these goals, the utility model is by the following technical solutions: a kind of high leak tightness is taken over trap valve soon, comprise valve body, valve body is provided with feed-water end and waterexit end, inner chamber between water end (W.E.) and waterexit end is provided with the cavity of an outside projection, and the opening end of cavity connects a plug, is provided with a filter screen in cavity, in filter screen insertion inner chamber, as filter member, the top of filter screen extends to the opening of cavity; The feed-water end of valve body and/or waterexit end connect a joint for plastic tube by locking nut, the junction of joint for plastic tube and valve body is provided with a seal ring, contact segment with locking nut on the outer wall of described joint for plastic tube is provided with an annular convex shoulder, and the inboard of locking nut is provided with the gear edge that coordinates with annular convex shoulder; Described seal ring is circular cone shape, and valve interior wall is provided with the seal ring contact segment conical surface that matches with the circular cone table top, and seal ring opening's edge and annular convex shoulder end face are conflicted.
As preferably, described annular convex shoulder is positioned at the end of joint for plastic tube, and the annular convex shoulder front end is provided with an annular boss, and seal ring is sheathed on this annular boss.
As preferably, described joint for plastic tube is PP-R pipe or PE pipe.
As preferably, the end of described valve body radially is provided with hexagonal tangent plane or anistree tangent plane.
In sum, this filter tap has the following advantages: the end of this valve body plastics Tube to tube fittings that directly is tightly connected, during use, only need tubing is connected with plastic pipe joint hot melting to get final product, and very convenient; And seal ring and valve body area of contact are large, good seal performance, and serviceability is high.

Fig. 2 is partial structurtes schematic diagram of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out clear, complete description.
As shown in Figure 1, a kind of high leak tightness is taken over trap valve soon, comprise valve body 1, valve body 1 is provided with feed-water end 11 and waterexit end 12, inner chamber 13 between feed-water end 11 and waterexit end 12 raises up and forms a cavity 14, be provided with a filter screen in cavity 14, filter screen inserts inner chamber 13 as the filter member of filter tap from cavity, and the top of filter screen extends to the opening of cavity 14; Plug 2 disengaging lids are placed in the opening of cavity 14, and filter screen is sealed and placed in cavity 14.
On valve body, feed-water end 11 is connected with the waterexit end by locking nut 7 connection one PPR joint for plastic tubes 5, two end part on valve body are provided with outside thread, the inwall of locking nut 7 is provided with the internal thread that matches with this outside thread, and joint for plastic tube 5 is provided with a seal ring 8 with the junction of valve body; As shown in Figure 2, contact segment with locking nut 7 on the outer wall of joint for plastic tube 5 ends is provided with an annular convex shoulder 51, the inboard of locking nut 7 is provided with the gear that coordinates with annular convex shoulder 51 along 71, seal ring 8 is circular cone shape, be provided with the seal ring contact segment conical surface 61 that matches with circular cone table top 81 on valve body 1 inwall, the conical surface 61 is conflicted with the end face of annular convex shoulder 51.Annular convex shoulder 51 front ends are provided with an annular boss 9, and seal ring 8 is sheathed on this annular boss 9; Joint for plastic tube 5 is the PP-R pipe, obviously, also can be for PE manages, the outer surface at the two ends of valve body is positioned at the outside thread inboard along radially being provided with the anistree tangent plane that coordinates with spanner, also is provided with anistree tangent plane at the outer surface of locking nut, conveniently screws.
During use, only need tubing is connected with plastic pipe joint hot melting to get final product, very convenient; The seal ring area of contact of this sealing configuration is large, and good seal performance is difficult for leaking, and very durable, when filter tap damages, only need back out locking nut, changes filter tap and gets final product.
